Frequently Asked Questions
When is the 2026 federal individual tax return due?
The 2025 tax year return (filed in 2026) is due on April 15, 2026. If you file for an extension using Form 4868 by April 15, you get until October 15, 2026 to file. Important: an extension gives more time to FILE, not more time to PAY โ any tax owed is still due by April 15.
When are 2026 quarterly estimated tax payments due?
The four 2026 estimated tax payment deadlines are: April 15, 2026 (Q1, covering JanโMar income); June 16, 2026 (Q2, covering AprโMay income); September 15, 2026 (Q3, covering JunโAug income); and January 15, 2027 (Q4, covering SepโDec 2026 income). Self-employed individuals and investors typically need to make these payments.
When is the S-Corp and partnership tax return due?
S-Corporation (Form 1120-S) and partnership (Form 1065) returns are due March 16, 2026 (the 15th falls on Sunday). With an extension, the deadline moves to September 15, 2026. These are flow-through entities โ partners and shareholders need the K-1 to complete their personal returns, hence the earlier deadline.
What is the deadline for employers to send W-2 and 1099 forms?
Employers must furnish W-2 forms to employees by January 31, 2026. Businesses must furnish 1099-NEC forms to independent contractors by January 31, 2026. The IRS filing deadline for employers is also January 31, 2026 for W-2s (to SSA) and 1099-NECs.
Are there special deadlines for US taxpayers living abroad?
US citizens and resident aliens living outside the US automatically receive a 2-month extension to June 16, 2026 for filing and paying tax (no Form 4868 required). You must attach a statement to your return explaining that you qualify. You can request an additional extension to December 15, 2026 by writing to the IRS.
