When you work for an employer, taxes come out of every paycheck without you lifting a finger. When you freelance, nobody does that for you. The IRS still expects to be paid as you earn, and the way you do that is through quarterly estimated tax payments.
This guide explains who has to pay, when the payments are due, how to work out how much to send, and exactly how to pay, with a worked example so you can see the numbers.
The short answer
- Who pays: if you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and credits, you generally need to make estimated payments.
- When (tax year 2026): April 15, June 15, September 15, and January 15, 2027.
- How much: enough to hit a “safe harbor” (see below), which for most freelancers means either 90% of this year’s tax or 100% of last year’s tax, divided into four payments.
- How to pay: online through IRS Direct Pay or your IRS Online Account, through EFTPS, or by mailing a check with a Form 1040-ES voucher.
- A rough rule of thumb: many freelancers end up setting aside about 20-30% of net profit for federal taxes. Your real number depends on your income, filing status and deductions, so calculate it rather than guessing.
Who needs to pay quarterly estimated taxes?
You generally need to make estimated payments if both of these are true:
- You expect to owe at least $1,000 in tax for the year after subtracting your withholding and refundable credits.
- Your withholding and credits will be less than the required annual payment (the safe harbor amounts below).
This applies to sole proprietors, independent contractors, gig workers, partners, and S corporation shareholders. It also applies to anyone with significant income that has no tax withheld: freelance work, side-hustle profits, rental income, interest, dividends, or capital gains.
Do you have a day job too? Then you might avoid estimated payments by increasing the withholding on your paycheck (Form W-4). Withholding is treated as paid evenly through the year, even if you change it late, which makes it a handy fix. Our guide to [internal link: side hustle taxes with a W-2 job] covers this.
First year freelancing? If you had no tax liability last year, one of the safe harbors may let you owe nothing in estimated payments this year. Check the rule in the FAQ below.
2026 estimated tax due dates
The tax year is split into four payment periods that are not equal quarters. That surprises a lot of people.
| Payment | Income earned | Due date (2026 tax year) |
|---|---|---|
| Q1 | January 1 – March 31 | April 15, 2026 |
| Q2 | April 1 – May 31 | June 15, 2026 |
| Q3 | June 1 – August 31 | September 15, 2026 |
| Q4 | September 1 – December 31 | January 15, 2027 |
When a due date falls on a weekend or legal holiday, it moves to the next business day.
Good to know: if you file your 2026 return and pay the full balance by the end of January (the IRS date for 2027 is a few days later because January 31 falls on a Sunday), you can skip the fourth payment. Confirm the exact date on IRS.gov.
Already missed a payment? Pay as soon as you can. The penalty works like interest on the amount you were short, so every day matters. See the section on missing or underpaying below.
Step-by-step: how to calculate your estimated payments
Step 1: Estimate your net profit for the year
Start with the income you expect from freelancing, minus your business expenses. That figure is your net profit, and it is the number your taxes are based on, not your gross revenue.
If you’re new and unsure, use last year’s numbers, or take your first two or three months and annualize them. Revisit the estimate each quarter. It’s far easier to adjust a payment than to explain a large bill in April. Not sure what counts as a deductible expense? See our checklist of [internal link: self-employed tax deductions].
Step 2: Calculate your self-employment tax
Self-employment (SE) tax is how freelancers pay Social Security and Medicare, the same taxes an employer and employee would split on a paycheck.
- The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.
- It applies to 92.35% of your net profit.
- For 2026, the Social Security portion applies only to the first $184,500 of earnings. The Medicare portion has no cap, and high earners may owe an Additional Medicare Tax on top.
- You can deduct half of your SE tax when calculating your income tax.
For a deeper explanation, read [internal link: Self-Employment Tax Explained].
Step 3: Estimate your federal income tax
Take your net profit, subtract half of your SE tax, then subtract your deductions, usually the standard deduction ($16,100 for single filers and $32,200 for married couples filing jointly in 2026) and the Qualified Business Income (QBI) deduction if you qualify. Then apply the tax brackets to the result.
This is where most freelancers want help. Form 1040-ES includes a worksheet, and the IRS offers a Tax Withholding Estimator, or you can use our [internal link: quarterly tax calculator].
Step 4: Pick your target (the safe harbor)
You avoid an underpayment penalty if you pay at least the smaller of:
- 90% of your tax for the current year, or
- 100% of your tax for the prior year (or 110% if last year’s adjusted gross income was above $150,000, or $75,000 if married filing separately).
The prior-year option is popular because you know the number in advance. The trade-off: if your income jumps, you will owe more in April, but you will not be penalized for it. If your income drops, the 90% route may mean paying less. Our full guide to the [internal link: safe harbor rule] shows how to choose.
Step 5: Divide by four and set the dates
Divide your target amount by four and put the four due dates in your calendar. If your income is uneven, you can use the annualized income installment method instead (more on that below).
Step 6: Pay and keep proof
Make each payment by the due date, using the methods in the next section. Save the confirmation. Record the payment as a tax payment, not a business expense, in your bookkeeping.
A worked example
Meet Sam, a single freelance designer who expects $60,000 in net profit in 2026 and has no other income. These figures are rounded and for illustration only.
| Item | Amount |
|---|---|
| Net profit | $60,000 |
| Self-employment tax: $60,000 × 92.35% × 15.3% | about $8,478 |
| Half of SE tax (deduction) | about $4,239 |
| Adjusted gross income | about $55,761 |
| Standard deduction (single, 2026) | $16,100 |
| QBI deduction (about 20% of $39,661) | about $7,932 |
| Taxable income | about $31,729 |
| Federal income tax (2026 brackets) | about $3,559 |
| Total federal tax (income tax + SE tax) | about $12,037 |
| Per quarterly payment (current-year method) | about $3,009 |
In this example Sam’s federal tax is about 20% of net profit, before any state tax. If Sam’s tax last year was $9,000, the prior-year safe harbor would require only $9,000 in total ($2,250 per quarter), as long as last year’s AGI was under $150,000. Sam would then owe the difference when filing. Sam might choose whichever approach fits cash flow better.
Your own numbers will differ, particularly with other income, a spouse’s income, health insurance deductions, retirement contributions or credits.
How to pay your estimated taxes
- IRS Direct Pay. Free. Pay straight from a checking or savings account at IRS.gov/payments. Choose “Estimated Tax” as the reason and select the correct tax year. You can schedule payments in advance.
- Your IRS Online Account. Lets you pay, see payment history, and manage scheduled payments.
- EFTPS (Electronic Federal Tax Payment System). Free, but you must enroll first, which can take a few days. Good for scheduling all four payments ahead of time.
- Debit or credit card. Possible through approved payment processors, which charge a fee. Usually not worth it unless you want card rewards or need short-term cash flow.
- Check or money order with Form 1040-ES. Mail it with the voucher to the address for your state, with your name, Social Security number, and “2026 Form 1040-ES” on the check. Allow plenty of mailing time.
Tip: always select the right tax year and payment type. A payment applied to the wrong year or labeled as a balance due is a common and avoidable headache.
What if your income is uneven?
Many freelancers earn most of their income in a few months, so equal payments can mean overpaying early. The annualized income installment method (Form 2210, Schedule AI) bases each payment on what you actually earned up to that point. It requires more paperwork, but it can lower or eliminate a penalty when your income is lumpy. This is a good moment to ask a tax professional. See [internal link: should you hire a CPA as a freelancer].
Don’t forget state estimated taxes
Most states with an income tax also expect quarterly payments, often on similar dates, though some use different rules. A few states, such as Texas, Florida, and Washington, have no broad income tax. Check your state’s tax agency website. Cities and a few localities may also levy their own taxes.
What happens if you miss or underpay?
There is no flat fine. Instead, the IRS charges an underpayment penalty that works like interest on the amount you were short, for the number of days it was unpaid. The rate is set quarterly and changes over time. You report it on Form 2210 when you file, or the IRS may calculate it and send you a bill.
A few points to keep in mind:
- The penalty is usually modest if you’re only slightly short, but it grows the longer the shortfall lasts.
- Paying late is better than not paying. Catch up as soon as you can.
- Limited waivers exist, for example after a casualty or disaster, or certain situations involving retirement or disability. Don’t assume you qualify; check the Form 2210 instructions.
- The penalty is separate from any late-filing or late-payment penalties on your return. Those can be more expensive. See [internal link: what happens if you don’t pay quarterly taxes].
Common mistakes to avoid
- Treating the quarters as equal. The four periods are 3, 2, 3, and 4 months.
- Basing payments on revenue instead of net profit. Subtract business expenses first.
- Forgetting self-employment tax. It’s often the largest surprise, especially at lower incomes.
- Spending the tax money. Move your set-aside amount into a separate savings account every time you get paid.
- Skipping state taxes. Many freelancers pay the IRS faithfully and then discover a state bill.
- Never updating the estimate. If your income changes, change your payments. Don’t wait for April.
Tools that make it easier
- The IRS Tax Withholding Estimator and the Form 1040-ES worksheet: free and authoritative.
- Accounting software that tracks income, expenses, and an estimated tax figure as you work. [Affiliate placement: link to best accounting software for freelancers.]
- A separate savings account for taxes, so the money is out of sight.
- A calendar reminder two weeks before each deadline.
FAQ
Do I need to pay estimated taxes if I only freelance part-time? Possibly. What matters is whether you expect to owe $1,000 or more after withholding and credits, not whether freelancing is your main job. Many people with a day job avoid quarterly payments by raising their paycheck withholding.
What if I don’t know my income yet? Use a reasonable estimate or last year’s figures, then adjust as the year goes on. Using the prior-year safe harbor gives you a clear target when income is unpredictable.
Can I pay more than the required amount? Yes. Overpayments are credited to your return and refunded or applied to next year. You won’t receive interest on money you overpay, so there’s no benefit in over-saving beyond avoiding surprises.
Do I pay estimated taxes if I’m a new freelancer with no tax last year? If you owed no tax last year and were a U.S. citizen or resident for the whole year, you may not need to make estimated payments this year under the prior-year safe harbor. The rule has conditions, so confirm it in Publication 505.
What’s the difference between estimated taxes and a tax return? Estimated payments are advance payments toward your annual tax bill. You still file a tax return after the year ends, where your actual tax is calculated and your payments are credited against it.
Key takeaways
- If you’ll owe $1,000 or more, pay quarterly. The 2026 dates are April 15, June 15, September 15 and January 15, 2027.
- Base the amount on net profit, include self-employment tax, and choose a safe harbor.
- Pay for free through IRS Direct Pay, your IRS Online Account or EFTPS.
- Revisit the estimate every quarter and don’t forget your state.
- Move your tax money into a separate account the day you get paid.
