2026 Tax & Payroll
Deadline Calendar.

Federal, Maryland, Virginia, and DC tax due dates for 2026 — including payroll deposit and filing deadlines. Bookmark this page, or let us track every date for you.

An extension to file is not an extension to pay. State deadlines don't always match the IRS. Missed estimated or payroll deposits trigger penalties that compound quickly. Below is a full-year view of what's due and when — and if you're already a client, there's nothing here you need to personally remember.

January 2026

Winding down 2025.

Q4 estimates, year-end W-2s and 1099s, payroll filings, and FUTA annual reports all land in January.

February 2026

Payroll deposits & 1099 corrections.

A quieter month — but payroll deposits continue on their regular schedule.

March 2026

Pass-through entities file first.

S-corps and partnerships are due a full month before individual returns — give us your documents early so we can make that deadline.

April 2026

The big one.

Individual returns, C-corp returns, Q1 estimates, IRA contributions, MD/VA state filings, and Q1 payroll returns — all in April.

May & June 2026

Q2 estimate & payroll deposits.

Payroll deposits continue monthly. The second quarterly estimate is due in June.

July 2026

Q2 payroll return.

The second quarterly payroll return and summer payroll deposits.

August & September 2026

Q3 estimate & extended business returns.

Extended S-corp and partnership returns have a hard September 15 deadline — no further extensions available.

October 2026

Final extended deadlines.

If you extended your individual or C-corp return in April, October 15 is the absolute last date to file. No more extensions.

November & December 2026

Year-end planning window.

The last chance to take actions that reduce your 2026 tax bill — before December 31 closes the door on this tax year.

January 2027

Looking ahead.

The calendar resets — Q4 estimates, year-end payroll filings, and the W-2/1099 cycle begin again.

Payroll — Quick Reference

Deposit schedules & recurring deadlines.

Your payroll tax deposit schedule is determined by your lookback period. Most small businesses are monthly depositors; larger payrolls may be semi-weekly.

Disclaimer: This calendar is for general informational purposes only. Deadlines shift when they fall on a weekend or federal holiday — verify final dates with the IRS or your state tax authority. State deadlines are subject to change. This is not tax or payroll advice — contact us for guidance specific to your situation.

"
Extensions give you more time to file — not more time to pay. That distinction costs clients more in penalties than almost anything else we see.
