Quarterly Estimated Taxes, Explained (2026 Dates + How to Pay)
Short answer: Quarterly estimated taxes are advance payments the IRS expects from self-employed people who will owe $1,000 or more for the year. For the 2026 tax year, the four due dates are April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. You can pay online in minutes through IRS Direct Pay or EFTPS, and paying enough on time protects you from underpayment penalties.
The U.S. tax system is pay-as-you-go. W-2 employees satisfy that through paycheck withholding; 1099 workers satisfy it by making estimated payments themselves. Here is how the system works and how to stay penalty-free.
What are quarterly estimated taxes?
Quarterly estimated taxes are periodic prepayments of the income tax and self-employment tax you expect to owe on income that has no withholding. This includes freelance and gig income, contractor pay, business profit, and often investment or rental income.
Each payment is not a separate bill. It is an installment toward one annual total, credited against what you owe when you file. The IRS overview is at irs.gov.
Who has to pay quarterly estimated taxes?
You generally must pay estimated taxes if both of these are true:
- You expect to owe at least $1,000 in tax for the year after subtracting withholding and refundable credits, and
- Your withholding and credits will be less than the smaller of 90% of this year’s tax or 100% of last year’s tax (110% if your prior-year adjusted gross income was over $150,000).
You typically do not need to make estimated payments if you had no tax liability last year, you were a U.S. citizen or resident for the whole year, and your prior tax year covered 12 months.
What are the 2026 quarterly estimated tax due dates?
The four federal deadlines for the 2026 tax year are below. If a date lands on a weekend or legal holiday, the deadline shifts to the next business day.
| Quarter | Income period covered | 2026 tax year due date |
|---|---|---|
| Q1 | January 1 – March 31, 2026 | April 15, 2026 |
| Q2 | April 1 – May 31, 2026 | June 15, 2026 |
| Q3 | June 1 – August 31, 2026 | September 15, 2026 |
| Q4 | September 1 – December 31, 2026 | January 15, 2027 |
Note that these “quarters” are not equal three-month blocks — Q2 covers two months and Q4 covers four. Mark all four dates now so none sneaks up on you.
How do I calculate what to pay each quarter?
There are two reliable approaches.
- The safe harbor method (simplest). Pay 100% of last year’s total tax (110% if your prior-year AGI exceeded $150,000), split into four equal payments. Do this and you generally avoid penalties even if you earn more this year.
- The current-year method. Estimate this year’s net profit, calculate the tax with Form 1040-ES, and pay 90% of it across the four installments. This fits better when your income is rising or falling sharply.
If your income is uneven, you can pay based on what you actually earned each period (the annualized income installment method), though it requires more bookkeeping.
How do I pay the IRS?
Paying is faster than filing. Your main options:
- IRS Direct Pay — pay directly from a checking or savings account with no fee, at irs.gov.
- EFTPS (Electronic Federal Tax Payment System) — free, lets you schedule payments in advance, and keeps a payment history.
- Debit or credit card — accepted through IRS-approved processors, but they charge a fee.
- Mail a check with a Form 1040-ES voucher, if you prefer paper.
Whatever method you choose, keep the confirmation. Your records are your proof the payment was made and on time.
Regional note: In the UK, self-employed people do not pay quarterly. HMRC uses Self Assessment with a balancing payment due January 31 and two “payments on account.” In Canada, the CRA may require quarterly instalments (due March 15, June 15, September 15, and December 15) when your net tax owing exceeds a set threshold.
What happens if I miss a quarterly payment?
The IRS can charge an underpayment penalty, calculated like interest on the amount you should have paid for the period you were short. Paying the full balance in April does not erase a penalty for missing earlier installments.
If you missed a quarter, do not wait for the next one — pay as soon as you can to stop the penalty from growing. Meeting the safe harbor over the year can reduce or eliminate the penalty.
How does staying organized make quarterly taxes painless?
Quarterly taxes are only stressful when you scramble to reconstruct your numbers four times a year. If your income, receipts, and mileage are already logged, each deadline becomes a quick review instead of a fire drill.
Keel: Invoice Maker & Receipts keeps those numbers current between deadlines. It creates invoices so your income is clear, captures receipts on your iPhone (the app proposes details from a scan and you approve), and tracks mileage at the 2026 IRS rate of 72.5¢ per mile. Everything stays encrypted on your device — no bank connection, no cloud, no account — and exports as one file when you calculate each payment or file your return. Keel is not a bank-linked automated all-in-one; the honest tradeoff for that privacy is a bit of manual entry, which many solo workers happily accept. Get Keel on the App Store.
Frequently asked questions
When are 2026 quarterly estimated taxes due? For the 2026 tax year, payments are due April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. Weekend or holiday dates shift to the next business day.
What is the safe harbor rule for estimated taxes? If you pay at least 100% of last year’s total tax (110% if your prior-year AGI was over $150,000), you generally avoid an underpayment penalty even if you owe more when you file.
Can I skip the January payment? You may skip the January 15, 2027 payment if you file your 2026 return and pay the balance in full by February 2, 2027. Otherwise, make the January installment on time.
Do I have to pay exactly one-quarter each time? No. You can pay unequal amounts based on when you earn, using the annualized income installment method. Most people pay equal amounts because it is simpler.
Do quarterly payments cover state taxes too? No. Federal estimated payments go to the IRS. If your state has income tax, it usually has its own separate estimated-payment schedule and portal.
