Frequently asked questions
- How do I calculate a quarterly tax payment?
- Estimate your annual federal income tax plus self-employment tax, subtract any withholding, then divide the remainder by four. This calculator does that from your income and expenses.
- When are 2026 quarterly tax payments due?
- April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If a date lands on a weekend or holiday it shifts to the next business day.
- Who has to make quarterly payments?
- Anyone expecting to owe $1,000 or more after withholding and credits — most 1099 contractors, drivers, creators, and freelancers.
- What happens if I skip a quarter?
- The IRS charges an underpayment penalty computed as interest on the shortfall from that quarter's due date. Paying late still reduces the penalty, so never skip a payment entirely.
- How do I actually pay?
- IRS Direct Pay is free and instant — choose 'Estimated Tax' and the 2026 tax year. EFTPS and the IRS2Go app also work.
- What if my income is uneven?
- You can use the annualized income installment method on Form 2210 Schedule AI to match payments to when you actually earned the income.
