Staying ahead of all your tax deadlines in 2026 is essential if you want to avoid unnecessary penalties, fees, and IRS hassles. With shifting tax rules, administrative turnover, and ongoing legislative changes, many taxpayers are asking a simple question: Are taxes still due in 2026?
The short answer: Absolutely.
Even though the tax landscape has been turbulent—marked by rapid commissioner changes, government staffing cuts, and the introduction of a new GOP tax and spending bill that created some temporary tax breaks while permanently removing others—the IRS still enforces an extensive calendar of filing and payment deadlines. Missing any of those dates can trigger penalties, interest, or both.
For example, failing to file a federal income tax return on time typically results in a 5% penalty per month (or part of a month) on the unpaid tax. Failure-to-pay penalties usually run 0.5% per month, up to 25% of the outstanding balance. Interest accrues on top of those penalties, and many other IRS obligations also carry their own consequences if ignored.
With at least one required deadline nearly every month, keeping everything straight can feel overwhelming. To simplify your year, here is a comprehensive breakdown of the major 2026 federal income tax deadlines for individuals—organized month by month.
Tax Deadlines
January 12
- Report December 2025 tips to your employer.
January 15
- Make your fourth-quarter 2025 estimated tax payment.
• Farmers and fishermen also make their estimated 2025 payment on this date.
January kicks off the new filing season and brings a few obligations right away. Tips earned in December must be reported early in the month, and the final 2025 estimated tax payment is due for most taxpayers. If you prefer not to make this quarterly payment, you can skip it only if you file and fully pay your 2025 tax bill by February 2, 2026 (adjusted because January 31 falls on a weekend).
Taxpayers affected by federally declared natural disasters may have different timelines depending on their extended IRS tax deadlines.
February 2
- Deadline to file and pay your 2025 taxes in full if you did not make the January estimated payment.
February 10
- Report January 2026 tips to your employer.
February 16
- File Form W-4 to reclaim your withholding exemption for 2026 (if eligible).
As usual, tip reporting continues on the 10th of the month—this time for January. The February 2 deadline applies only to individuals relying on full payment instead of a January installment. And if you previously qualified for exemption from income tax withholding, you must file a new W-4 by the 16th.
March 2
- Farmers and fishermen must file their 2025 tax return to avoid penalties if no January estimated payment was made.
March 10
- Report February 2026 tips.
March 16
- S-Corporations and partnerships must file their 2025 business tax returns.
March is relatively light but includes the business filing deadline for S-Corps and partnerships. Monthly tip reporting remains standard.
April 1
- First required minimum distribution (RMD) for individuals who turned 73 in 2025.
April 10
- Report March 2026 tips.
April 15 (Major Deadline Day)
- File your 2025 federal income tax return and pay any taxes due.
• File Form 4868 to request a six-month filing extension (tax payments still due April 15).
• File Schedule H and pay taxes for household employees, if applicable.
• Make first-quarter 2026 estimated tax payment.
• Make 2025 IRA and HSA contributions.
• Withdraw any excess IRA contributions for 2025 (if not filing an extension).
• Self-employed taxpayers can contribute to a solo 401(k) or SEP plan for 2025 (if not filing an extension).
• File a 2022 tax return to claim an unclaimed refund.
April is the busiest month of the tax year. Beyond your federal return, this month also handles retirement contributions, HSA funding, employer tax responsibilities for household workers, and RMD obligations. Anyone turning 73 must take their first RMD by April 1, while inherited IRAs follow different rules.
May 11
- Report April 2026 tips.
May 15
- Calendar-year tax-exempt organizations must file applicable Form 990 series returns unless they filed an extension.
Only two deadlines appear in May. Tip reporting continues, and nonprofit organizations must meet their filing requirements unless they requested the automatic extension.
June 10
- Report May 2026 tips.
June 15
- Make second-quarter 2026 estimated tax payment.
• U.S. taxpayers living abroad must file their 2025 return.
• Same deadline for expats to file Form 4868 for a four-month extension (tax not extended).
• Military personnel stationed outside the U.S. also must file their 2025 return or request an extension.
June is particularly important for individuals working overseas or serving abroad, as they receive an automatic two-month extension to file.
July 10
- Report June 2026 tips.
This is a quiet month for tax obligations unless you earned tips over the $20 threshold.
August 10
- Report July 2026 tips.
The only deadline this month relates to tip reporting.
September 10
- Report August 2026 tips.
September 15
- Make third-quarter 2026 estimated tax payment.
Keep track of both your quarterly estimated tax payments and employer tip reports this month.
October 12
- Report September 2026 tips.
October 15
- File your extended 2025 tax return (Form 1040).
• Withdraw excess 2025 IRA contributions if you filed an extension.
• Self-employed taxpayers who filed an extension may contribute to a solo 401(k) or SEP for 2025.
October primarily impacts taxpayers who filed for an extension in April.
November 10
- Report October 2026 tips.
Only a single deadline applies—tip reporting if your income exceeded $20 from any employer during the month.
December 10
- Report November 2026 tips.
December 31
- Make final 2026 contributions to employer-sponsored retirement plans (401(k), 403(b), 457, TSP).
• Take your annual RMD if you are 73 or older by year-end.
December marks the close of the tax year, and retirement contributions and RMD compliance are the most important tasks to complete before the calendar resets.
