TAX FILING DEADLINE 2026

Tax deadline 2026: the extension deadline is October 15.

If you filed an extension back in April, your return is due October 15. The extension moved the paperwork and nothing else. Whatever you owed was due on April 15, and it has been sitting there ever since.

Those are the federal dates for calendar-year filers, and your state keeps a calendar of its own. The rest of them sit below, with the part no deadline page tells you.

This goes to us and nowhere else, only so we can reply about your Second Look.

The dates, plainly

The extension date is the live one, so it goes first. Confirm any of these on the IRS site for the year you are filing, and remember your state runs a calendar of its own.

Extended individual returns: October 15

The extension is automatic and it runs six months from the April date, which puts the finished return due on October 15. The IRS is blunt about what that buys you: an extension of time to file is not an extension of time to pay. If you owed in April, the extension did nothing about that part, and October is simply when the paperwork stops being optional.

Individual returns: April 15

April 15 in a normal year, moving to the next business day when that date falls on a weekend or a holiday. Quarterly estimated payments sit on their own schedule through the year, so if nobody ever set those up for you, April is where four manageable payments arrive as one uncomfortable number.

S corporations and partnerships: mid March

A calendar-year S corporation or partnership files a month ahead of you, with an extension that runs into September. Your personal return waits on that one, which is how a date in March that nobody was watching becomes the week you are having right now. Twenty minutes on the phone will tell you what you are actually looking at.

How you got to this week

  • December closed with nobody asking what the year would owe
  • The return went to someone who called you once, for documents
  • An extension filed to buy time, with the payment still sitting there
  • A real tax plan quoted separately, at $15,000

How the next one goes

  • Someone watching the March and April dates so they stop ambushing you
  • Books closed every month, so April holds no surprises
  • Decisions made while the year is still open and they still count
  • Twenty minutes on last year's return before you commit to anything

What people ask in the last week before a deadline

I filed an extension. What is actually due in October?

The return itself, finished, with every schedule attached. October 15 is a filing date and it touches nothing about the money. The IRS says it plainly: an extension of time to file is not an extension of time to pay, and you were meant to pay what you owed by the April date. So if the April estimate came up short, that shortfall has been outstanding since spring and now the paperwork has to arrive as well. Bring what you have to the twenty minutes and we will tell you which of those two problems you are really dealing with.

What if I miss the October date?

You file anyway, and you file as soon as you can. That is the IRS position in its own words for anyone who has not filed for this year or for prior years. The charge for filing late and the charge for paying late are separate things, and both keep running while a return sits unfiled, so waiting is neither free nor flat. We will not promise you relief from any of it. People in federally declared disaster areas sometimes have a later date than everyone else, so the IRS website is worth a look before you assume the worst. Then book the twenty minutes and let us get the thing filed.

My deadline is in a few days. Is it too late to call?

No, and the order of operations matters more than the speed. The first job is getting the filing handled correctly, which sometimes means extending and paying a carefully estimated amount rather than rushing a return nobody has read. We will not tell you that what is already late stops being late, because nobody can do that. Book the twenty minutes and you will at least know exactly where you stand today.

Nothing is filed and my books are behind. Where do we start?

With what is due first, and with whatever records actually exist. You do not need clean books to have this conversation. You need them to have a plan, and telling you which of the two you are dealing with is part of the call. Steven Palmieri will say what can be rebuilt quickly and what waits until the filing is off your desk.

Why does this happen every single year?

Because filing and planning are separate jobs and most people only ever buy the first one. A return records decisions you already made. The decisions themselves live in the months before the year closes, while an entity election, a retirement contribution or the timing of a large purchase can still move. If the only contact you get is a request for documents in March, the outcome was settled long before anyone opened your file.

Is the plan a separate fee?

No. Sold on its own, a tax plan is a $15,000 project with a deliverable and an end date. Here it comes with the monthly work and gets revisited as the year moves, because a plan written once in February has stopped matching your business by September.

Do you file the returns, and do you handle audits?

We prepare and file business and personal returns, and we keep the books behind them. We do not perform audits, reviews, or compilations, and we do not take collection cases. If a lender needs audited or reviewed statements, a licensed accounting firm does that piece. Bring your return to the twenty minutes and you will see how the rest of it works.
