Tax extension services in Las Vegas for individuals, couples and businesses
Quick answer: A federal tax extension is, for most filers, an automatic extra six months to file the return. iQTAXX prepares and e-files federal tax extensions for Las Vegas individuals and businesses: Form 4868 for personal returns (extended to October 15), Form 7004 for partnerships, S corporations, C corporations, estates and trusts, and Form 8868 for nonprofits. An extension gives you more time to file, never more time to pay, so we also estimate what you owe and help you pay it by the original due date to keep penalties and interest as low as the rules allow.
By the iQTAXX tax team, 6360 S Rainbow Blvd, Suite 101, Las Vegas. Updated October 30, 2026. Every federal rule on this page was checked on October 30, 2026 against the 2025 Form 4868, the Instructions for Form 7004 (December 2025), the IRS pages for Form 8868, the 2025 instructions for Forms 1065, 1120-S, 1120, 1041 and 990, Publication 509, and the IRS penalty and interest pages. Nevada facts were checked against the Nevada Constitution and the Nevada Department of Taxation.

For married couples filing jointly who want to save on taxes
Most of our extension clients are married couples filing jointly, and the main reason they extend is not laziness. It is a missing Schedule K-1 from a rental partnership, a corrected 1099 from a brokerage, a business that closed its books late, or a decision that deserves more thought, like whether to file jointly or separately. One Form 4868 covers both spouses on a joint return, and the IRS form has a box for your spouse's Social Security number for that reason (Form 4868).
An extension is a filing tool, not a tax-saving tool. What can lower a couple's tax legally is the work done with the extra time: checking that every deduction and credit is supported, reviewing joint versus separate filing before you file (Publication 501 says that once you file a joint return, you can't choose separate returns for that year after the due date), and planning the next year's estimated payments. We do that work all year, not just in tax season, and we never promise a result, because the outcome depends on your numbers. See our tax planning service for the year-round side.
| What couples usually need | How the extension helps | What it does not change |
|---|---|---|
| Waiting on a K-1 from a rental or business partnership | Gives you until October 15 to file once with the real numbers | Tax you owe is still due April 15 |
| Comparing married filing jointly with married filing separately | Time to run both versions before choosing | Once you file jointly, you generally can't switch to separate after the due date |
| One spouse self-employed (trucking, rideshare, real estate) | Time to finish the Schedule C or Schedule E records | Self-employment tax and income tax are still due April 15 |
| Funding a SEP-IRA for a self-employed spouse | SEP contributions can be made up to the extended due date | Traditional and Roth IRA contributions are still due in April |
| A new baby, marriage, divorce or death in the family | Time to gather documents and get the filing status right | Your filing status is still based on December 31 |

Key facts about tax extensions (checked October 30, 2026)
- Extensions are automatic. You don't have to explain why you're asking, and the IRS contacts you only if the request is denied (Form 4868). For business extensions, the IRS "will no longer send a notification that your extension has been approved" and notifies you only if it is disallowed (Instructions for Form 7004).
- No extension of time to pay. "An extension of time to file is not an extension of time to pay" (IRS: When to file). Form 7004 says the same: it "does not extend the time to pay tax" (Instructions for Form 7004).
- Personal returns: Form 4868 gives six more months, to October 15. For tax year 2026 the dates are Thursday, April 15, 2027 and Friday, October 15, 2027.
- Partnerships and S corporations: returns are due the 15th day of the 3rd month (March 15 for calendar-year filers), and Form 7004 gives an automatic 6-month extension (Publication 509).
- Estates and trusts (Form 1041): the extension is 5½ months, not 6 (Instructions for Form 1041).
- Nonprofits (Form 990): due the 15th day of the 5th month (May 15 for calendar-year filers) and extended 6 months with Form 8868 (Instructions for Form 990, IRS exempt organization extensions).
- One form per return. "File a separate Form 7004 for each return for which you are requesting an extension" (Instructions for Form 7004).
- Nevada has no personal income tax, so there is no Nevada individual extension (Nevada Constitution, Art. 10, Sec. 1). Larger businesses that owe the Nevada Commerce Tax have a separate 30-day state extension form (Nevada Department of Taxation).
- Interest runs from the original due date even with an extension; the IRS underpayment rate for individuals is 7% a year, compounded daily, for the quarter that began October 1, 2026 (IRS interest rates).
Who do we file tax extensions for?
We file extensions for people and businesses whose return we are preparing, or will prepare, at our Las Vegas office. The table below shows the clients we see most often and the extension each one needs.
| Client | Return | Extension form | Typical reason to extend |
|---|---|---|---|
| Married couple filing jointly | Form 1040 | Form 4868 (one form for both spouses) | Waiting on K-1s, brokerage corrections or a filing-status decision |
| Single filer or head of household | Form 1040 | Form 4868 | Missing W-2, 1099 or records after a move or job change |
| Owner-operator trucker | Form 1040 with Schedule C | Form 4868 | Per-diem, fuel and depreciation records not finished |
| Rideshare or delivery driver | Form 1040 with Schedule C | Form 4868 | Mileage log and 1099-K or 1099-NEC still being reconciled |
| Rental property owner | Form 1040 with Schedule E | Form 4868 | Property-manager statements, depreciation or a 1031 exchange |
| Single-member LLC (default) | Form 1040 (Schedule C or E) | Form 4868 | The LLC is disregarded, so the owner's personal extension covers it |
| Multi-member LLC (default) or partnership | Form 1065 | Form 7004 | Partner K-1s can't go out until the books close |
| S corporation (including an LLC taxed as an S corp) | Form 1120-S | Form 7004 | Year-end payroll, reasonable salary and shareholder K-1s |
| C corporation | Form 1120 | Form 7004 | Year-end close, depreciation and estimated tax reconciliation |
| Estate or trust | Form 1041 | Form 7004 (5½ months) | Valuations, final distributions or a late K-1 |
| Nonprofit or exempt organization | Form 990, 990-EZ, 990-PF or 990-T | Form 8868 | Audit or board review not finished |
Sources: IRS: Limited liability company, Instructions for Form 7004, About Form 8868, Instructions for Form 1041.
The IRS treats a domestic LLC with at least two members as a partnership unless it elects to be taxed as a corporation, and treats a one-member LLC as "disregarded as separate from its owner" unless it elects otherwise (IRS: Limited liability company). That is why the right extension form depends on how your LLC is taxed, not on the word "LLC" in its name. If you aren't sure how your Nevada LLC files, our business tax service and incorporation service pages explain the choices, and our post on the financial advantages of forming a Nevada LLC covers the state side.
Which extension form do you need? Forms 4868, 7004 and 8868 compared
| Feature | Form 4868 | Form 7004 | Form 8868 |
|---|---|---|---|
| Who uses it | Individuals (Forms 1040, 1040-SR, 1040-NR, 1040-SS) | Partnerships, S corporations, C corporations, estates, trusts and many other business and information returns | Exempt organizations (Forms 990, 990-EZ, 990-PF, 990-T and others) and trusts filing Form 1041-A or 5227 |
| Length of extension | 6 months (4 more months for U.S. citizens and residents out of the country, who already have an automatic 2) | Generally 6 months; 5½ months for estates and trusts on Form 1041 | 6 months |
| Must explain why? | No | No | No |
| Extends time to pay? | No | No | No |
| One form covers | Your whole return (both spouses on a joint return) and also extends the gift tax return, Form 709, for the same year | One return only; a separate Form 7004 for each return | One return for one tax year |
| How to file | E-file, a paper form, or an electronic payment marked as an extension | E-file for most returns, or paper | E-file (except some requests, such as for Form 8870) or paper |
| IRS approval notice | Only if denied | Only if disallowed | Only if denied |
Sources: Form 4868, About Form 4868, Instructions for Form 7004, About Form 7004, About Form 8868, Form 8868, IRS exempt organization extensions.
Form 8868 can't be used to extend a Form 990-N (the e-Postcard), and an organization is allowed only one 6-month extension for a return for a tax year (IRS exempt organization extensions). Trusts that file Form 1041-A must use Form 8868 instead of Form 7004 (Instructions for Form 7004).
When are extended returns due in the 2027 filing season (tax year 2026)?
These are the dates for calendar-year 2026 returns. When a due date falls on a Saturday, Sunday or legal holiday, it moves to the next business day (IRS: When to file). The IRS confirms each year's dates in its filing-season announcements, so we recheck these every January.
| Return | Original due date (file the extension by) | Extended due date | Extension form |
|---|---|---|---|
| Form 1065 partnership or multi-member LLC | Monday, March 15, 2027 | Wednesday, September 15, 2027 | Form 7004 |
| Form 1120-S S corporation | Monday, March 15, 2027 | Wednesday, September 15, 2027 | Form 7004 |
| Form 1040 individual or couple | Thursday, April 15, 2027 | Friday, October 15, 2027 | Form 4868 |
| Form 1040 for U.S. citizens and residents abroad | Tuesday, June 15, 2027 (automatic 2 months) | Friday, October 15, 2027 | Form 4868 (check the out-of-country box) |
| Form 1120 C corporation | Thursday, April 15, 2027 | Friday, October 15, 2027 | Form 7004 |
| Form 1041 estate or trust | Thursday, April 15, 2027 | Thursday, September 30, 2027 | Form 7004 (5½ months) |

| Form 709 gift tax | Thursday, April 15, 2027 | Friday, October 15, 2027 | Extended by your Form 4868 (or Form 8892) |
Sources: Publication 509, Instructions for Form 1065, Instructions for Form 1120-S, Instructions for Form 1120, Instructions for Form 1041, Instructions for Form 990, Form 4868. Dates for 2027 are the statutory dates applied to the 2027 calendar.
Still open right now (October 30, 2026): a calendar-year nonprofit that filed Form 8868 for its 2025 Form 990 has until Monday, November 16, 2026 (November 15 falls on a Sunday). Every other 2025 extended deadline on this table has passed. If your 2025 personal or business return is still not filed, call us and see what to do about a missed deadline below.
Which business extension dates catch Las Vegas owners?
Business owners get caught by the March date more than any other. A partnership or S corporation return is due a month before your personal return, and the IRS late filing penalty for those returns is charged per owner, so a small LLC with several members can run up a penalty even when the business owes no tax at all.
| Return | Late filing penalty (from the 2025 IRS instructions) | Late payment penalty | Who pays the tax |
|---|---|---|---|
| Form 1065 partnership | 255 dollars for each month or part of a month late (up to 12 months), multiplied by the number of partners | None at the entity level for ordinary income tax | Partners, on their own returns |
| Form 1120-S S corporation (no tax due) | 255 dollars per month or part of a month (up to 12 months), multiplied by the number of shareholders | Not applicable when no tax is due | Shareholders, on their own returns |
| Form 1120-S S corporation (tax due) | The per-shareholder amount plus 5% of unpaid tax per month, up to 25%; minimum for a return over 60 days late is the smaller of the tax due or 525 dollars | ½ of 1% of unpaid tax per month, up to 25% | The corporation, for entity-level taxes |
| Form 1120 C corporation | 5% of unpaid tax per month, up to 25%; same minimum for a return more than 60 days late | ½ of 1% of unpaid tax per month, up to 25% | The corporation |
Sources: Instructions for Form 1065, Instructions for Form 1120-S, IRS failure to file penalty, Instructions for Form 7004. These are IRS penalty figures, not iQTAXX fees.
A corporation that gets an extension avoids the late payment penalty for the extension period if the tax it paid by the regular due date is at least 90% of the tax on its return and it pays the balance by the extended due date (Instructions for Form 7004). Interest still runs from the original due date. Estates and trusts are treated a little differently: a trust filing Form 1041 "will be granted an extension even if it cannot pay the full amount," but it should pay as much as it can to limit penalties and interest.
A few more Form 7004 details we handle so you don't have to:
- Name and number must match IRS records. If the name on Form 7004 doesn't match the IRS database or the identifying number is wrong, "you will not have a valid extension" (Instructions for Form 7004). We use the name exactly as it appeared on last year's return.
- A new address on Form 7004 doesn't update your IRS record. A move needs Form 8822-B for a business.
- Paper extension plus e-filed return can cause a penalty notice, because the return may be processed before the paper extension is. We e-file both.
- Consolidated groups file one Form 7004 through the parent, with a list of every member.
How does the iQTAXX extension process work?
We keep the process simple and in person or by phone. Here is what happens from your first call to the day your return is filed.
| Step | What happens | Who does it | When |
|---|---|---|---|
| You call 702-871-7884 and tell us which returns you need extended (personal, business or both) | You | As early as possible, and before the original due date |
| You bring or send the basics: names, Social Security numbers or EIN, last year's return, and this year's income so far | You | A few days before the deadline at the latest |
| We estimate your total tax for the year and subtract withholding and estimated payments already made | iQTAXX | Before the original due date |
| You decide how much to pay with the extension; we show you the IRS payment options (Direct Pay, EFTPS, or electronic funds withdrawal with the e-filed form) | You, with our help | By the original due date |
| We e-file Form 4868, 7004 or 8868 and keep the IRS acknowledgment in your file | iQTAXX | By the original due date |
| We prepare the full return as your missing documents arrive | iQTAXX and you | Before the extended due date |
| We set next year's estimated payments or withholding so you don't have to extend again for the same reason | iQTAXX and you | When the return is filed |
The Form 4868 instructions say you should "properly estimate your 2025 tax liability using the information available to you" and enter it on the form (Form 4868). A wild guess can make the extension invalid, which is why we build the estimate from real numbers: last year's return, year-to-date pay stubs, business profit and loss, and any 1099s you already have.
The IRS also lets you get a personal extension just by paying all or part of your estimated tax electronically and marking it as an extension payment; in that case "you don't have to file Form 4868" (Form 4868). Businesses don't get that shortcut: Form 7004 must be filed for each return. Most entities must make federal tax deposits by electronic funds transfer, usually through EFTPS (Instructions for Form 7004). Individuals can use IRS Direct Pay.
What to bring for a tax extension appointment
You don't need every tax document to file an extension. You need enough to make a reasonable estimate. Bring what you have; we will tell you what is missing for the full return later. Our items to bring page has the full checklist for the return itself.
| For a personal extension (Form 4868) | For a business extension (Form 7004 or 8868) |
|---|---|
| Names, Social Security numbers and dates of birth for you, your spouse and dependents | Legal business name exactly as on last year's return, and EIN |
| Last year's federal return | Last year's business return and K-1s |
| Year-end pay stubs or W-2s received so far | Profit and loss and balance sheet through year end, even if not final |
| 1099s, 1099-K and 1099-NEC forms received so far | Payroll reports (Forms 941 and W-3) for S corporations |
| Records of estimated tax payments made for the year | Estimated tax payments made by the business (for C corporations) |
| A list of what is still missing (K-1s, corrected 1099s, property statements) | Names of all partners or shareholders and their ownership share |
| Bank account and routing number if you want to pay electronically | The bank account the business uses for IRS payments |
What extension issues come up in trucking, rideshare and real estate?
Three industries make up a large share of our extension clients, and each one has a predictable reason to extend.
| Industry | Common reason to extend | What the extension doesn't cover | Related page |
|---|---|---|---|
| Trucking (owner-operators) | Per-diem, fuel, maintenance and truck depreciation records not finished by April | Form 2290 heavy highway vehicle use tax is a separate return with its own due date (generally August 31 for vehicles first used in July) | Self-employed tax preparation |
| Rideshare and delivery | Reconciling 1099-K and 1099-NEC income with a mileage log and app summaries | The income tax and self-employment tax are still due April 15 | Rideshare and gig driver taxes |
| Real estate (landlords and investors) | Waiting on partnership K-1s, property-manager statements, or a depreciation schedule | The 1031 exchange identification deadline (45 days) doesn't move | Real estate investor taxes |
| Real estate agents | Commission 1099s and business expense records | Quarterly estimated taxes for the new year | Personal tax service |
Sources: Instructions for Form 2290, Instructions for Form 8824, IRS: When to file.
For real estate investors doing a 1031 exchange late in the year, the extension can matter more than people expect. The replacement property must be received within 180 days of the transfer or by the due date (including extensions) of your return for that year, whichever comes first, so a return filed on April 15 can cut the 180-day window short (Instructions for Form 8824). Extending the return keeps the full window available. If your extension is tied to an S corporation you own, see our S corporation tax preparation page too.
Do you need a Nevada or other state extension?
| Situation | State extension needed? | Notes |
|---|---|---|
| Nevada resident individual or couple | No | Nevada has no personal income tax, so there is no Nevada individual return or extension |
| Nevada LLC, partnership or corporation (income tax) | No | Nevada has no corporate income tax; the federal Form 7004 is the only income tax extension |
| Business with Nevada gross revenue over 4 million dollars a year | Only if it can't file the Commerce Tax return on time | The Commerce Tax return is due 45 days after the June 30 fiscal year end (August 14, 2026 for the 2025-2026 year); the state has a separate 30-day extension of time to file and pay |
| Business owner with income from another state | Possibly | That state's rules apply; some states accept the federal extension and some need their own form |
| Former California resident in a move year | Possibly | California has its own automatic extension rules, and payment is still due in April |
Sources: Nevada Constitution, Art. 10, Sec. 1, Nevada Department of Taxation, Commerce Tax, California FTB due dates.
The Nevada 30-day Commerce Tax extension is a separate state form filed with the Nevada Department of Taxation, and it is an extension of time to file and pay, which is different from federal extensions (Nevada Department of Taxation).
What penalties and interest apply if you file or pay late?
The penalties are where an extension earns its keep. The federal late filing penalty is ten times the late payment penalty per month, so filing on time (or extending on time) matters even when you can't pay.
| Charge | Rate | Starts | Stopped by an extension? |
|---|---|---|---|
| Failure to file penalty | 5% of unpaid tax per month or part of a month, up to 25% | The day after the due date, including extensions | Yes, while the extension lasts |
| Minimum penalty, return more than 60 days late (filed in 2026) | The smaller of 525 dollars or 100% of the unpaid tax | 60 days after the due date, including extensions | Yes, if you file by the extended date |
| Failure to pay penalty | 0.5% of unpaid tax per month, up to 25% | The day after the original due date | Only if you meet the 90% rule and pay the rest by the extended date |
| Both penalties in the same month | The 5% is reduced by the 0.5%, so 5% in total | Same month | Partly |
| Interest | Set by the IRS each quarter; 7% a year for individuals for the quarter starting October 1, 2026, compounded daily | The original due date | No |
Sources: IRS failure to file penalty, IRS failure to pay penalty, IRS interest, IRS interest rates for the fourth quarter of 2026, Form 4868. The 525-dollar figure is an IRS minimum penalty, not an iQTAXX fee.
For individuals, the 90% rule works like this: if at least 90% of your total tax is paid by the original due date through withholding, estimated payments and the extension payment, and you pay the rest with your return by the extended date, the IRS treats you as having reasonable cause for the late payment during the extension (Form 4868). That is why our estimate step matters.
Penalty relief is changing in 2026. The IRS is moving from First Time Abate to a new Automatic Exemption from Penalty (AEP) that begins with 2025 tax year returns. If you file or pay late but filed and paid on time for the three prior years, the IRS won't assess the failure to file, failure to pay or failure to deposit penalties, and it sends a letter saying relief was applied. It covers Forms 1040, 1065 and 1120, among others. Interest and the unpaid tax are still owed (IRS administrative penalty relief). If you don't qualify, reasonable cause relief may still apply.
Can't pay the tax? Extend anyway
If you owe and can't pay, the worst choice is to do nothing. File the extension on time (or file the return), pay what you can, and set up an IRS payment plan for the rest (IRS payment plans). An on-time extension keeps the late filing penalty from starting while it lasts, and the IRS lets many people and businesses apply for a payment plan online. If you already have IRS letters, our IRS resolutions service can help you answer them.
| If you... | Do this by the original due date | Then |
|---|---|---|
| Can pay in full | File the extension and pay your estimate | File the full return before the extended date |
| Can pay part | File the extension and pay what you can | Apply for a payment plan for the rest once the return is filed |
| Can't pay anything yet | File the extension anyway | Pay as soon as you can; interest and the 0.5% penalty run until paid |
| Expect a refund | An extension is optional, but it protects you if your estimate is wrong | Penalties are a percentage of unpaid tax, so with nothing owed there is no penalty |
| Are in a federally declared disaster area | Check whether the IRS has postponed your deadline | IRS disaster relief can move filing and payment dates automatically |
Sources: IRS payment plans, IRS failure to pay penalty, IRS: Tax relief in disaster situations.
Missed the extended deadline? What to do now
An extension can't be filed after the original due date has passed. If your extended deadline has already gone by, the extension no longer helps, but filing quickly still does, because the failure to file penalty keeps adding 5% a month until it reaches 25%. We prepare past-due returns, figure the penalty, and check whether you may qualify for AEP, First Time Abate or reasonable cause relief. Call us at 702-871-7884; we are open in November and December too, not only in tax season.
| Missed date | What to do |
|---|---|
| October 15, 2026 for a 2025 personal return | File the 2025 return as soon as possible and pay what you can |
| September 15, 2026 for a 2025 partnership or S corporation return | File now; the per-owner penalty adds up each month (up to 12) |
| September 30, 2026 for a 2025 trust or estate return | File now and pay as much as possible |
| You never filed an extension for 2025 | Same answer: file now; there is no late extension |

Why do Las Vegas clients use iQTAXX for extensions?
- Open year-round, not seasonal. We have served Las Vegas since 2008 and we answer the phone in July and November, when extended returns are due, not only in April.
- Personal and business extensions under one roof. A couple with an S corporation needs a Form 7004 in March and a Form 4868 in April; we track both and finish the business return first so the K-1 is ready for the personal one.
- Estimates built from your real numbers, so your extension is valid and your payment is as close as possible to what you will owe.
- Featured industries: trucking, rideshare and real estate, the three groups whose records most often take extra time.
- Fees depend on the forms your return needs. Call 702-871-7884 for a quote. Booking is by phone call only.
We can't promise a refund or a penalty outcome, because those depend on your facts and the IRS. What we can do is file your extension correctly and on time, explain what you owe and why, and prepare the full return before the extended date.
What do clients say about iQTAXX?
These are real reviews from our public Google and Yelp profiles, quoted word for word (typos included). They describe iQTAXX as a company, not this specific topic, and no review predicts the outcome of your return. As of October 30, 2026, iQTAXX is rated 4.7 out of 5 from about 149 Google reviews and 4.3 out of 5 from 188 Yelp reviews.
★★★★★ 5 out of 5. “I’ve been with IQtaxx for over 14 years, and I honestly can’t imagine trusting anyone else with my taxes. Krystal has been my go-to tax preparer from day one—she’s sharp, professional, and always makes sure everything is done right. She handles both my personal and business taxes, and every year, she makes a stressful process feel smooth and manageable. Krystal takes the time to explain things, answers all my questions, and I always feel confident that I’m in great hands.

Frequently asked questions
What does iQTAXX's tax extension service include?
We estimate your tax for the year, show you how much to pay by the original due date, e-file the right extension form (Form 4868, 7004 or 8868), keep the IRS acknowledgment, and then prepare the full return before the extended deadline. Our fees depend on the forms your return needs. Call 702-871-7884 for a quote.
How long does a tax extension last?
Form 4868 gives individuals six more months, to October 15. Form 7004 gives most business returns six months, except estates and trusts on Form 1041, which get 5½ months. Form 8868 gives nonprofits six months.
What is the deadline to file a business tax extension in 2027?
For calendar-year 2026 returns, partnerships and S corporations must file Form 7004 by Monday, March 15, 2027. C corporations, estates and trusts must file it by Thursday, April 15, 2027.
Does a tax extension give me more time to pay?
No. An extension gives you more time to file, not more time to pay. Tax not paid by the original due date is charged interest from that date, and usually a late payment penalty of 0.5% a month.
Do married couples need two extensions?
No. If you file a joint return, one Form 4868 covers both spouses. If you plan to file separately, each spouse files their own Form 4868.
Which extension form does my LLC use?
It depends on how the LLC is taxed. A single-member LLC that hasn't elected corporate treatment is part of the owner's personal return, so Form 4868 covers it. A multi-member LLC is a partnership by default and uses Form 7004. An LLC taxed as an S corporation or C corporation also uses Form 7004.
Does Nevada require a state tax extension?
Not for income tax. Nevada has no personal or corporate income tax. Businesses with Nevada gross revenue over 4 million dollars a year file the Nevada Commerce Tax return, which has its own 30-day extension form.
Do I need an extension for my S corporation and my personal return?
Usually yes, two of them. The S corporation files Form 7004 by March 15, and you file Form 4868 by April 15 for your personal return. The S corporation extension doesn't extend your personal return.
What happens if my business misses the extension deadline?
The extension can't be filed late. A partnership or S corporation that files late can be charged 255 dollars for each month or part of a month (up to 12 months) times the number of partners or shareholders. An S corporation that owes tax can also owe 5% of the unpaid tax a month. File as soon as possible and ask us about penalty relief.
Can you file a tax extension if I haven't started my return?
Yes. An extension needs a reasonable estimate, not a finished return. Bring last year's return and what you have for this year, and we will build the estimate from that.
Is it too late to file an extension for 2025?
Yes for most returns. The 2025 extension deadlines were in March and April 2026, and the extended personal deadline was October 15, 2026. If your 2025 return isn't filed, file it as soon as possible to stop the late filing penalty from growing.
Do truckers, rideshare drivers and real estate investors need a different extension?
No. Self-employed people and landlords who file on their personal return use Form 4868. Truckers should know that the Form 2290 heavy vehicle use tax is a separate return with its own due date.

This page is general information only and is not legal or tax advice. IRS rules and deadlines change, so check the linked IRS sources and consult a qualified tax professional about your own situation before you act. An extension gives you more time to file, not more time to pay, and is not a promise of any result.
