Paying your estimated taxes is a critical requirement for anyone whose income isn't subject to automatic withholding, such as freelancers, small business owners, and those with significant investment income. If you expect to owe $1,000 or more when you file your return, the IRS generally requires you to make these payments in four installments throughout the year to avoid penalties.

Determining Your Payment Amount

To calculate your payment, you must estimate your adjusted gross income, taxable income, and deductions for the year. The IRS provides Form 1040-ES , which includes a worksheet to help you find this total. You can avoid underpayment penalties by paying at least 90% of your current year's expected tax or 100% of the tax shown on last year's return.

EFTPS| Electronic Federal Tax Payment System 15.| Recurring payments and business users.
IRS2Go App| Mobile application for tax payments 9.| Payments on the go via mobile devices.

2026 Deadlines

Quarterly payments are due on specific dates throughout the year. If a deadline falls on a weekend or legal holiday, the payment is typically due the next business day.

  • April 15, 2026 : Payment for income earned Jan 1 – March 31.
  • June 15, 2026 : Payment for income earned April 1 – May 31.
  • September 15, 2026 : Payment for income earned June 1 – Aug 31.
  • January 15, 2027 : Final payment for income earned Sept 1 – Dec 31.

Important Considerations

  • Penalties and Interest : Failing to pay enough throughout the year can result in an underpayment penalty, and the IRS also charges interest on unpaid balances—currently around 7% compounded daily.
  • State Taxes : Most states also require estimated tax payments; be sure to check your specific state's Department of Revenue for their rules and portals.
  • Safe Harbor : If your adjusted gross income was over $150,000 last year, you must pay 110% of your prior year's tax to meet the "safe harbor" requirement.
