Filing
The return goes in. March for a calendar-year S corporation or partnership. April for an individual or a calendar-year C corporation.
One phrase is doing the work of two acts. This site is not the IRS. The return has a day, and the balance can have a different one. The gap is the point.
People hear a single deadline and picture one circle on a calendar. That wish is reasonable. A return and a payment are still two acts, and they only share a date when the instructions for that form put them together. Wanting one day is how the second day gets missed.
There is no countdown and no penalty percent on this page.
Filing
The return goes in. March for a calendar-year S corporation or partnership. April for an individual or a calendar-year C corporation.
Paying
The balance is a second act. It can share the filing day, or it can stay on the original day when the return moves.
Sources. IRS Publication 509 for calendar-year filers, read 3 October 2026. An individual and a calendar-year C corporation file on the 15th day of the fourth month. A partnership and an S corporation file on the 15th day of the third month. When that day is a Saturday, a Sunday, or a legal holiday, the next business day is used. A named year's weekday is kept on the year list, not in this gap. Sources. Texas Comptroller franchise tax page, comptroller.texas.gov/taxes/franchise/, read 3 October 2026. The report is due 15 May, or the next business day when the 15th is a weekend or a holiday. The no tax due line on that rates page is 2,650,000 dollars for reports due in 2026 and 2027. A public or ownership report can still be required underneath it. Sources. IRS estimated taxes page for small businesses and the self-employed, irs.gov/businesses/small-businesses-self-employed/estimated-taxes, read 3 October 2026. An estimate is a payment on its own slip. Harbor percentages are left off this page on purpose.
No one here holds a CPA license. This desk does not sign an audit, a review, or a compilation, and it does not pitch a settlement of a penalty.
Payroll deposits are not the filing day of an income tax return. The full statement of that limit is on the disclosures page.
Once the two acts are named, the useful want is a month that has already closed, so the filing day can be met without a scramble. Controller work is the closed month and the return on its day. The CFO work is noticing the payment day while you can still meet it.
Breadth is the books, the return, and both dates from one desk. Height is seeing the gap before the spring date is behind you. A Tax CFO holds that seat. The gap stays the answer to the phrase you came with.
I was looking for the tax filing deadline. I want the filing day and the payment day, even when they are not the same.
You will be talking to the Steven Palmieri practice.
