If you work for yourself, no employer is withholding tax from your pay, so the IRS expects you to pay as you earn, in four estimated payments a year. Missing them can mean penalties, and a big bill at tax time is a shock. This checklist walks you through setting up, each quarterly payment for the 2026 tax year, and filing. Tick each step as you go. Your progress is saved in your own browser.

The dates and rules here are for United States federal taxes and the 2026 tax year. State rules differ. This is general information, not tax advice, so if your situation is complicated, such as multiple states, a business entity or large income swings, talk to a qualified tax professional.

Set up once 0 of 6

Do these first and the rest of the year is easier.

  1. Keeping business income apart from personal spending makes your profit easy to see. A separate savings account just for taxes makes it easy to set money aside as you are paid.

  2. Record income from every client and platform. You owe tax on self-employment income even if you never receive a 1099 form. Forms such as the 1099-NEC and 1099-K are reports, not the source of your obligation.

  3. Keep receipts and records for ordinary and necessary business costs. If you drive for work, keep a mileage log. Tax is charged on profit, so accurate expenses directly lower your tax.

  4. On top of income tax, you pay 15.3% self-employment tax (Social Security and Medicare) on 92.35% of your profit. Half of it is deductible. Run your numbers to see the total.

  5. Most states that have an income tax also expect estimated payments from self-employed people. Find your state revenue department's rules and due dates, which are often the same as the federal ones.

  6. For 2026, federal estimated payments are due April 15, June 15 and September 15, 2026, and January 15, 2027. Set reminders a week ahead.

Quarter 1: January to March, due April 15, 2026 0 of 3

Covers income earned from January 1 through March 31.

  1. Add up income and subtract business expenses for the period. If income is uneven, use your best estimate for the whole year.

  2. You can pay for free with IRS Direct Pay or your IRS online account, use EFTPS, or mail a check with a Form 1040-ES voucher. Save the confirmation.

  3. Use your state's own payment system and keep the confirmation with your records.

Quarter 2: April and May, due June 15, 2026 0 of 3

This period is only two months long, which surprises many people.

  1. Update your year-to-date profit and your estimate for the full year.

  2. Pay the same way as before and save the confirmation.

  3. Check the due date for your state, which can differ from the federal date.

Quarter 3: June to August, due September 15, 2026 0 of 3

Covers income earned from June 1 through August 31.

  1. Check your year-to-date profit against your estimate. Adjust your payment if your income has changed a lot.

  2. If you missed an earlier payment, pay as soon as you can. Penalties are based on how much was owed and for how long.

  3. Keep the confirmation with your other records.

Quarter 4: September to December, due January 15, 2027 0 of 3

Covers income earned from September 1 through December 31.

  1. Now you can see your whole year. Compare your actual profit with what you estimated.

  2. The IRS says you can skip this payment if you file your return and pay the full balance by the end of January. Otherwise pay by January 15.

  3. Check your state's due date and whether it matches the federal one.

Turn the year of records into a return.

  1. Clients and payment platforms may send Forms 1099-NEC, 1099-K or 1099-MISC. Compare them with your own records, and report all your income even if a form is missing.

  2. Total your income and subtract your deductible expenses. This is the profit reported on Schedule C.

  3. A SEP IRA or Solo 401(k) can lower your taxable income while you save for retirement. Contribution rules and deadlines differ by plan, so check them before the year ends.

  4. Schedule C reports your profit, and Schedule SE calculates self-employment tax. Compare your total tax with what you paid in estimates and pay any balance or claim any refund.

  5. A common safe harbor is to pay at least 90% of this year's tax, or 100% of last year's (110% if last year's adjusted gross income was above $150,000). Use last year's return to set a starting amount.

Common mistakes to avoid

  • Setting aside only an income-tax percentage. Self-employment tax is a second bill. At $80,000 of profit, the two together come to about a quarter of your profit. Run your numbers instead of guessing.
  • Waiting for a 1099 before reporting income. Income is taxable whether or not a form arrives. Track your own payments all year.
  • Forgetting that quarters are uneven. The second payment covers only April and May, and the fourth covers four months. Look at the dates, not just "every three months".
  • Mixing business and personal money. It makes profit hard to calculate and expenses hard to prove. A separate account solves both.
  • Ignoring state estimated taxes. Many states want estimated payments too, and they can have their own penalties.
  • Paying late without paying at all. A late payment is usually better than none, because penalties depend on how much was owed and for how long.

Frequently asked questions

When are quarterly estimated taxes due?

For the 2026 tax year the federal due dates are April 15, June 15 and September 15, 2026, and January 15, 2027. If a date falls on a weekend or holiday it moves to the next business day. State due dates can differ.

Do I have to pay quarterly taxes?

Generally, if you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and credits, the IRS expects estimated payments. If you also have a job, you can often raise your paycheck withholding on Form W-4 instead. Check the current IRS rules or ask a tax professional.

How do I know how much to pay?

Estimate your profit for the year, then calculate self-employment tax and income tax on it. The self-employment tax calculator on this site does that and shows a suggested quarterly payment. Many people pay a quarter of the yearly total each time and adjust if their income changes.

What is the safe harbor rule?

You generally avoid an underpayment penalty if you pay at least 90% of this year's tax or 100% of last year's tax, whichever is smaller. The prior-year percentage rises to 110% if last year's adjusted gross income was above $150,000. Ask a tax professional which rule suits you.

How do I pay the IRS?

The common ways are IRS Direct Pay (free, from a bank account), your IRS online account, the Electronic Federal Tax Payment System (EFTPS), a card through an approved processor (which charges a fee), or a check with a Form 1040-ES voucher.

What if I missed a quarterly payment?

Pay as soon as you can. The penalty is figured separately for each payment period, based on how much you underpaid and for how long, so paying late is better than not paying. You may also be able to reduce the penalty when you file. Ask a tax professional if the amount is large.
