What matters now
- Calendar-year filers must file federal income tax returns by April 15, 2026.
- Fiscal-year filers file by the 15th day of the fourth month after their tax year ends.
- If the deadline falls on a weekend or legal holiday, the IRS shifts it to the next business day.
- This article covers only the federal filing deadline, not state deadlines or payment due dates.
If you file taxes on a calendar-year basis, the IRS deadline to file your federal individual income tax return is April 15, 2026 (irs.gov). If you file on a fiscal year instead, your deadline is the 15th day of the fourth month after your fiscal year ends (irs.gov). In either case, if that date falls on a Saturday, Sunday, or legal holiday, the IRS pushes the deadline to the next business day (irs.gov).

Key points
- Calendar-year filers: the IRS states, “File on: April 15, 2026” (irs.gov).
- Fiscal-year filers: the IRS states, “File on: The fourth month after your fiscal year ends, day 15.” (irs.gov).
- Weekend/holiday rule: “If day 15 falls on a Saturday, Sunday or legal holiday, the due date is delayed until the next business day” (irs.gov).
- This article covers only the federal filing deadline — not disaster relief, state deadlines, or the payment due date.
Calendar-year deadline
For most individual taxpayers, who report income on a calendar-year basis, the IRS is explicit about the date: “File on: April 15, 2026” (https://www.irs.gov/filing/individuals/when-to-file). In practical terms, this is the standard, published due date for the current filing season, and it requires no calculation on the taxpayer’s part.
This article reports the federal filing date shown on the cited IRS page. It does not address any other filing requirement.
Fiscal-year filing rule
Not every filer uses the calendar year. For those who file on a fiscal year, the IRS describes the rule this way: “File on: The fourth month after your fiscal year ends, day 15.” (https://www.irs.gov/filing/individuals/when-to-file). In practice, this means a fiscal-year filer counts four months forward from the close of their tax year and files by the 15th day of that fourth month.
IRS Publication 509’s tax calendar table also lists a due date of “the 15th day of the 4th month after the end of your tax year” (irs.gov) for one of the forms in that table. The publication’s own quoted line does not identify which form the entry covers, so this article treats it only as a similar due-date pattern appearing elsewhere in the IRS tax calendar rather than as separate confirmation of the individual fiscal-year rule described above.
This article does not address payment timing or any other obligation associated with a return.
Weekend and holiday rule
Both calendar-year and fiscal-year deadlines are subject to the same weekend-and-holiday rule. The IRS states: “If day 15 falls on a Saturday, Sunday or legal holiday, the due date is delayed until the next business day.” (https://www.irs.gov/filing/individuals/when-to-file). In practical terms, this means the filing deadline can shift forward by a day or more depending on the calendar in a given year, and filers should check the current published date rather than assume the 15th always applies.
This article does not address any other reason a filing date might differ.
