How to Pay Quarterly Taxes When You Are Self-Employed

Learning how to pay quarterly taxes is the biggest administrative jump between employment and working for yourself. Nobody withholds anything for you anymore, so the IRS asks you to send money four times a year instead.

After walking dozens of freelancers through their first year on their own, I can tell you the payment itself takes about ten minutes. What trips people up is the math and the calendar, not the mechanics.

This guide covers who owes estimated payments, the exact due dates, three ways to calculate what you owe, five ways to send it, and what it costs you if you get it wrong.

Who has to pay estimated taxes

The threshold is simple. If you expect to owe at least $1,000 in tax for the year after subtracting withholding and refundable credits, the IRS expects estimated payments.

That $1,000 covers everything, not just income tax. Self-employment tax counts toward it, which is why most freelancers clear the threshold on fairly modest revenue.

The IRS lays out the full rules on its estimated taxes page. Worth ten minutes if this is your first year on your own.

Two ways out of quarterly payments

You can skip estimated payments entirely if you had no tax liability in the prior year, you were a US citizen or resident for that whole year, and the prior tax year covered twelve months.

There is also a workaround if you have a W-2 job alongside freelance income. Withholding is treated as paid evenly across the year no matter when it happens, so bumping up withholding on the W-2 can cover the whole obligation without a single estimated payment.

I have used that second approach with several clients who freelance on the side. It converts four deadlines into one form filed with an employer.

Quarterly tax due dates

There are four dates and they are not evenly spaced. The second period is only two months long, which surprises people every single year.

Notice the last row. January 15, 2028 lands on a Saturday and the following Monday is a federal holiday, so that payment shifts to Tuesday, January 18.

Deadlines always move to the next business day when they fall on a weekend or holiday. Check the date each year rather than assuming the 15th.

One useful escape hatch on the January payment: you can skip it entirely if you file your return and pay the full balance by February 1 of the following year.

How to pay quarterly taxes: five methods

Every one of these stays open until 11:59 p.m. Eastern on the due date. I have listed them roughly in the order I recommend them.

1. IRS Direct Pay

This is what I tell almost everyone to use. IRS Direct Pay debits your bank account with no fee and no registration.

You verify your identity against a prior-year return, select “estimated tax” and the correct tax year, enter the amount, and confirm. Save the confirmation number, because it is your proof of timely payment.

You can schedule payments ahead of the due date. I have clients who set all four the moment they finalize their numbers in January.

2. EFTPS

The Electronic Federal Tax Payment System is also free and it keeps a permanent record of every payment you have made.

The catch is enrollment. The IRS mails you a PIN, so plan for it to take a week or more before your first payment can go through.

EFTPS is the better choice if you make many payments a year or want a single place to pull your full payment history at filing time.

3. Your IRS online account

An IRS online account lets you pay and see your balance, payment history, and prior-year figures in one place.

That last part matters more than people expect. If you use the safe harbor method, your prior-year total tax is the only number you need, and this is where you look it up.

4. Debit or credit card

The IRS uses third-party processors for card payments and each charges a fee. Debit is a small flat fee, credit is a percentage of the payment.

It is worth it in exactly two situations. You are chasing a signup bonus that exceeds the fee, or you need to hit the deadline today and a bank transfer will not clear in time.

5. Mail a check with Form 1040-ES

Form 1040-ES includes four payment vouchers, one per period. Mail the voucher with a check or money order to the address listed for your state.

Write your Social Security number, the tax year, and “Form 1040-ES” on the check itself. If it gets separated from the voucher, that is the only way the IRS can apply it correctly.

Mail it early. This is the slowest method and the only one where a postal delay can actually cost you.

How much to send: three calculation methods

The amount is not arbitrary. The IRS gives you three ways to arrive at it, and choosing the right one is where most of the savings hide.

Method 1: the prior-year safe harbor

This is the simplest and the one I recommend to anyone whose income is growing. Take your total tax from last year’s return, divide by four, and pay that.

Pay 100% of last year’s total tax and you are protected from underpayment penalties no matter what this year brings. If your prior-year adjusted gross income was over $150,000, the requirement rises to 110%.

The appeal is certainty. You are working from a number that already exists on a filed return instead of forecasting income you have not earned yet.

The downside is cash flow. If you expect to earn less this year, the safe harbor overpays and you are lending the IRS money interest-free until you file.

Method 2: current-year estimate

Here you project this year’s income and pay 90% of the resulting tax. It is more work and it is the right call when your income is dropping.

The process runs in five steps. Estimate net self-employment income, calculate self-employment tax, calculate federal income tax on your projected total, add state tax if your state has one, then divide by four.

Accuracy matters here. Underestimate badly and you land back in penalty territory, so I usually pad the projection by 5% to 10%.

Method 3: the annualized income installment method

This one is for seriously lumpy income. Instead of four equal payments, you calculate what you owe based on what you actually earned through each period.

If you close a large contract in the first quarter and go quiet in the second, this method lets your payments follow that shape. It requires Schedule AI on Form 2210 and careful records.

I only recommend it when the swings are large enough to justify the paperwork. For most freelancers with variable income, the prior-year safe harbor gets you the same protection for a fraction of the effort.

A worked example

Meet Sarah, a freelance copywriter. She is single, has no dependents, lives in a state with no income tax, and expects $85,000 in net self-employment income for the 2026 tax year.

Step 1, self-employment tax. Only 92.35% of net earnings are subject to it. That is $78,497.50, and 15.3% of that comes to about $12,010.

Step 2, the deduction for half. She deducts roughly $6,005 of that self-employment tax, bringing her adjusted gross income to about $78,995.

Step 3, deductions. The 2026 standard deduction for a single filer is $16,100, leaving $62,895. The qualified business income deduction removes another $12,579, for taxable income of about $50,316.

Step 4, federal income tax. Using the 2026 brackets for single filers, 10% applies to the first $12,400 and 12% to the remainder. That works out to roughly $5,790.

Step 5, the quarterly number. Add $12,010 and $5,790 for a total near $17,800. Divided by four, Sarah sends roughly $4,450 per period.

This is illustrative and ignores credits, retirement contributions, and any state tax. It does show why the self-employment tax portion is usually the larger half of the bill.

What you are actually paying

A quarterly payment is not one tax. It bundles at least two and often three, which is why the total feels heavier than people expect.

Self-employment tax

Self-employment tax funds Social Security and Medicare. It runs 15.3%, split as 12.4% for Social Security and 2.9% for Medicare.

The Social Security portion applies only up to an annual wage base, which is $184,500 for 2026. Medicare has no cap, and an additional 0.9% Medicare tax applies to earnings above $200,000 for single filers or $250,000 for joint filers.

A W-2 employee sees 7.65% withheld because the employer pays the other half. You pay both halves, though you deduct the employer-equivalent portion against your income tax.

Federal income tax

On top of self-employment tax you owe ordinary income tax on your profit. The rate depends on your total taxable income and your filing status.

Deductions matter enormously here because they reduce both taxes at once. Our guide to Schedule C expenses covers what is claimable line by line.

State income tax

Most states levy their own income tax and many run their own estimated payment schedule with their own deadlines. Eight states have no individual income tax at all.

Rates and rules vary sharply. If you are in a high-tax state, our California self-employment tax guide shows how much a state obligation can add to a quarterly payment.

What happens if you underpay

The IRS charges interest on any shortfall, calculated from the due date of each period until you pay it. This applies even if you end up getting a refund at filing time, which catches people off guard.

The rate resets quarterly. For the quarter beginning October 1, 2026, the IRS set the individual underpayment rate at 7% per year, compounded daily.

Take a $2,000 shortfall on an April payment that you do not settle until you file the following April. At that rate you are looking at roughly $140 in additional interest.

There is a separate failure-to-pay penalty of 0.5% of the unpaid balance per month once a tax bill is due and unpaid. The IRS explains how both work on its penalties page.

None of this is catastrophic on small amounts. It is simply an avoidable cost, which is the whole argument for using the safe harbor.

How to pay quarterly taxes without thinking about it

The freelancers who never stress about these deadlines all built the same handful of systems. None of them require discipline in the moment.

Set aside a percentage of every payment

The day a client payment lands, move a fixed percentage into a separate account. Most solo business owners land somewhere between 25% and 35% of gross.

This works because it does not depend on forecasting. Whatever you earn, the same slice comes off the top.

Use a dedicated tax savings account

Keep the money somewhere you will not casually spend it. A separate high-yield account creates just enough friction to stop you dipping into it.

It also makes payment day trivial. You transfer from one clearly labeled account and you are done.

Automate the transfer

If your income is steady, skip the per-payment step and set a fixed monthly transfer instead. Expect $60,000 and set aside 30%, and that is $1,500 on the first of every month.

By each deadline you will have roughly a quarter of your annual obligation sitting there. No decisions required.

Track deductions year-round

Estimated payments are based on net profit, so every legitimate deduction lowers what you send. Waiting until April to reconstruct them costs real money.

Keep running records of mileage, home office, software, professional development, health insurance premiums, and retirement contributions. Our step-by-step bookkeeping guide covers a workflow that takes about twenty minutes a week, and our QuickBooks best practices for the self-employed covers the software side.

Use retirement contributions deliberately

A SEP-IRA or solo 401(k) contribution reduces your income tax and therefore your quarterly payments. It is the rare move that shifts money from the IRS to your own balance sheet.

Note that it does not reduce self-employment tax. Plan the contribution before year end rather than discovering it at filing time.

Frequently asked questions

Do I have to pay quarterly taxes in my first year of self-employment?

Yes, if you expect to owe $1,000 or more for the year. First-year projections are guesswork, so estimate conservatively and adjust in later periods as your actual income becomes clear.

What if I miss a quarterly deadline?

Pay as soon as you can, because interest accrues from the original due date until you pay. There is no separate late-filing penalty for an estimated payment, so a payment a few days late costs very little.

Are quarterly taxes the same thing as self-employment tax?

No. Self-employment tax is the 15.3% that funds Social Security and Medicare. A quarterly estimated payment bundles that together with federal income tax and, in most states, state income tax.

Which form do I use to pay quarterly taxes?

Form 1040-ES if you are mailing a check, since it contains the payment vouchers. If you pay electronically through IRS Direct Pay, EFTPS, or your IRS online account, you do not file anything. You report the year’s income and payments on your annual Form 1040 with Schedule C and Schedule SE.

Can I skip a payment if I earned nothing that period?

Under the current-year method, yes, since your payment tracks actual income. Under the prior-year safe harbor you would still send the scheduled installment, because that method divides last year’s total tax into four equal parts.

How much should I set aside for quarterly taxes?

Most self-employed people I work with set aside 25% to 35% of gross income. Lean toward the higher end if you are in a state with income tax or your profit margin is high relative to revenue.

Do I need to pay state estimated taxes too?

In most states, yes, and the deadlines do not always match the federal ones. Check your state revenue department, since eight states have no individual income tax and several others set their own schedule.
