Tax deadlines are easier to manage when they are part of your calendar—not a last-minute surprise. Use this 2026 guide to organize federal filing, extension, and estimated-payment dates, then carry the same planning rhythm into future years.
Deadlines can shift when they fall on a weekend or federal holiday, and state due dates may differ. Confirm the final date that applies to your return before filing.
Key federal tax dates for 2026
January 15, 2026
Fourth-quarter 2025 estimated tax payment. This generally applies to self-employed people, freelancers, investors, and others whose withholding did not cover enough tax during 2025.
April 15, 2026
Individual income-tax return and payment deadline. This is also the typical deadline to request an automatic filing extension and to make the first-quarter 2026 estimated tax payment. An extension gives more time to file—not more time to pay.
June 15, 2026
Second-quarter 2026 estimated tax payment. Qualifying U.S. citizens and resident aliens living and working abroad generally receive an automatic two-month filing extension, though interest may apply to tax unpaid after April 15.
September 15, 2026
Third-quarter 2026 estimated tax payment. This is also the typical extended filing deadline for calendar-year partnerships and S corporations.
October 15, 2026
Extended individual return deadline. Taxpayers who requested a valid six-month extension generally must file by this date.
January 15, 2027
Fourth-quarter 2026 estimated tax payment. Add this date to your calendar now so the 2026 tax year closes smoothly.
Dates business owners should track
- March 16, 2026: typical filing deadline for calendar-year partnerships and S corporations because March 15 falls on a Sunday.
- April 15, 2026: typical deadline for calendar-year C corporations and sole proprietors filing Schedule C.
- Quarterly payroll filings: employers should track Form 941 and deposit deadlines throughout the year.
- January 31 obligations: because January 31, 2026 falls on a Saturday, some information-return deadlines shift to the next business day. Verify the exact Form W-2 and 1099 due dates that apply.
A system that works every year
- Schedule reminders 30 days and seven days before each deadline.
- Close bookkeeping monthly and reconcile every bank and payment-processor account.
- Review estimated payments whenever income changes significantly.
- Send documents to your tax professional early instead of waiting for the deadline.
- Check the IRS calendar annually for weekend, holiday, and disaster-relief changes.

November–December 2024: Year-End Tax Prep Tips
1. Organize Your Financial Records
Why It’s Important: Gather documents now to avoid a scramble in the new year. Freelancers and small business owners should focus on tracking income and deductible expenses, like business-related travel, equipment, and professional services.
Action Steps:
- Organize receipts and invoices by category.
- Review bank statements for business expenses you may have overlooked.
- Use accounting software or consult with a professional to streamline this process.
2. Maximize Tax-Deferred Contributions
Why It’s Important: Contributions to tax-deferred accounts reduce your taxable income. Consider topping off your contributions to accounts like a 401(k), traditional IRA, or Health Savings Account (HSA) before the year-end deadline.
Action Steps:
- Check your current contribution levels and see how much room you have before hitting annual limits.
- Make a final contribution to your IRA or HSA by December 31 to potentially reduce your 2024 tax bill.
Quick Tip: Not sure how much to contribute to see a meaningful tax benefit? Schedule a tax planning session with DownieTax to get a tailored strategy.
3. Complete Year-End Tax Planning
Why It’s Important: Year-end tax planning is essential to make sure you’re not leaving any potential savings on the table. A professional review can identify deductions, credits, and strategies tailored to your specific situation—whether you’re a freelancer, a small business owner, or an individual taxpayer.
Action Steps:
- Review your taxable income and plan for adjustments (like accelerating certain expenses or deferring income).
- Check eligibility for credits like the Earned Income Tax Credit or American Opportunity Credit.
- Evaluate whether to make additional charitable donations before December 31 for a tax deduction.
