Federal and Nevada due dates for individuals, self-employed professionals, and businesses — all in one place. Filter by what applies to you, see what's coming up next, and add deadlines straight to your calendar.
Key concepts that affect when you need to file and pay.
Tax year vs. filing year
The tax year is the period your income and expenses cover — for most people and businesses, January 1 to December 31. The filing year is when you report it. For example, income earned during 2025 is reported on returns filed in 2026. Each deadline on this page shows both its calendar date and the tax year it relates to.
Filing deadlines vs. payment deadlines
A filing deadline is the date a return or form must be submitted. A payment deadline is the date tax must be paid. They are often the same day, but not always: an extension gives you more time to file, never more time to pay. Estimated tax installments are payment-only deadlines, while many information returns are filing-only. Each deadline here is labeled Filing, Payment, or Filing & Payment.
How tax extensions work
Individuals can get an automatic 6-month extension to file by submitting Form 4868 by the April deadline; businesses use Form 7004. An extension only moves the filing date. You should still estimate and pay what you owe by the original deadline to avoid interest and failure-to-pay penalties.
Calendar-year vs. fiscal-year businesses
Most businesses use a calendar year, and the dates on this page assume one. Fiscal-year businesses use a 12-month period ending in a month other than December, so their deadlines shift: partnerships and S corporations file by the 15th day of the 3rd month after year-end, and C corporations generally by the 15th day of the 4th month. Nevada's Commerce Tax always follows the state's July 1 – June 30 fiscal year.
Weekend, holiday, and disaster adjustments
When a due date falls on a Saturday, Sunday, or legal holiday, it moves to the next business day. This calendar applies that rule automatically and notes when a date has moved. The IRS also postpones deadlines for taxpayers in federally declared disaster areas — check IRS disaster relief announcements if you live or do business in an affected area.
