Need More Time for Federal Taxes?
Washington Has No State Income Tax.
Washington doesn't tax individual income, so you only need to file a federal extension. File Form 4868 to get until October 15 for your federal return.
What is a Washington Tax Extension?
Washington state does not have a personal income tax, so there's no state tax extension needed. You only need to file a federal extension (Form 4868) to get more time for your federal return. This gives you until October 15 to file your federal taxes.
Extension to File ≠ Extension to Pay
A tax extension gives you more time to file your return — not more time to pay any taxes owed. If you expect to owe taxes, you should estimate and pay by April 15 to avoid interest and penalties.
You Should File an Extension If…
Missing Key Documents
Still waiting on W-2s, 1099s, or K-1s and can't file accurately yet.
Major Life Event
Marriage, divorce, new baby, or home purchase has changed your situation.
Complex Income
Self-employment, freelance, investments, or rental property to organize.
Living Abroad
Living or traveling abroad and need more time to coordinate.
Business Financials
Waiting on partnership returns or business P&L statements.
Just Need More Time
Collect receipts, organize records, and breathe. That's perfectly okay.
Filing an extension is completely normal. Millions of Americans — from individuals to large corporations — do it every year.
Creator Tip: Washington has no state income tax, making it one of the most tax-friendly states for individuals. Your main focus is filing your federal Form 4868 or 7004 through Otto. If you have a business, you may need to deal with Washington's B&O tax instead.

What If You Miss the Federal Filing Deadline?

- Failure-to-Pay Penalty 0.5% of unpaid taxes / mo
- Maximum Penalty 25% of total taxes owed
- IRS Scrutiny Increased audit risks
If You File an Extension
- Failure-to-File Penalty $0 (Completely Avoided)
