Quarterly taxes for the first time, in one sentence: if you expect to owe $1,000 or more for 2026 and nobody withholds from your pay, you send the IRS four payments during the year instead of one in April. The dates never move, the amount is simple math, and the penalty for getting it wrong is interest-sized, not catastrophe-sized.

Here is the whole system — the same one our self-employed and 1099 tax planning team sets up for first-year 1099 workers every spring.

Do I have to pay quarterly taxes my first year self-employed?

You have to make estimated payments for 2026 if you expect to owe at least $1,000 in federal tax after withholding and credits, and your withholding will cover less than the smaller of 90% of your 2026 tax or 100% of your 2025 tax. That two-part test comes straight from Form 1040-ES (2026), and it exists because 1099 and gig income has no withholding — the IRS still wants its money as you earn it.

One exception matters a lot for first-timers. No 2026 estimated payments are required if all three of these are true:

• You had no tax liability for 2025 — your total tax was zero, or you weren't required to file.
• You were a U.S. citizen or resident alien for the whole year.
• Your 2025 tax year covered a full 12 months.

Read that carefully, though. “No tax liability” means zero tax on the return, not “I got a refund.” A W-2 worker who got a refund last year still had tax on line 24 of their 2025 Form 1040, and that number becomes their safe-harbor target. And even if you qualify for the exception, the full 2026 bill is still due with your return by April 15, 2027 — the exception waives the installments, not the tax.

When are the 2026 quarterly estimated tax payments due?

For 2026, the four estimated tax payments are due April 15, June 15, September 15, 2026, and January 15, 2027. You can also pay the whole year's estimate in one shot by April 15, 2026.

Two things trip up first-timers here:

• The periods are uneven on purpose. The second “quarter” covers only April and May — two months — while the fourth covers four. Don't assume each payment covers three months of income.
• There's an escape hatch on the last one: you can skip the January 15, 2027 payment entirely if you file your 2026 return by February 1, 2027 and pay the full balance with it.

If you mail a payment, the postmark date counts as the payment date. And if it's easier to pay weekly or monthly, the IRS says that's fine — as long as each period's total is in by its due date.

How much should each quarterly tax payment be?

The simplest safe target is last year's total tax — line 24 of your 2025 Form 1040 — divided by four. Pay that and the underpayment penalty is off the table no matter how much you end up owing for 2026. If your 2025 adjusted gross income was over $150,000 ($75,000 if married filing separately), use 110% of last year's tax instead.

If you had no 2025 tax liability, the prior-year test is 100% of zero — so nothing is required, as covered above. But “nothing required” and “nothing due in April” are different things, so most first-timers should estimate this year's actual bill and pay 90% of it across the four dates. Here's what that looks like for a single filer with $30,000 of 2026 freelance profit:

• Self-employment tax: $30,000 × 92.35% = $27,705 of net earnings, taxed at 15.3% ≈ $4,239. (That 15.3% is both halves of Social Security and Medicare, charged on 92.35% of profit — the mechanics are in our guide to how self-employment tax works.)
• Income tax: after the deductible half of SE tax, the $16,100 standard deduction for 2026, and the qualified business income deduction ≈ $943.
• Total federal ≈ $5,182, or four payments of about $1,296. Pay 90% ($1,166 each) and the penalty question is settled even if your estimate is off.

Notice the split: over 80% of that bill is self-employment tax, not income tax. That's the surprise that hits every first-year gig worker, and it's why we built a walkthrough on figuring out what you owe on 1099 income before you commit to a number. If you drive for a delivery app, the mileage deduction changes this math significantly — our DoorDash taxes guide covers that side.

“I am a first-time consultant and filing my 1st quarterly self-employed taxes. Which tax form should I use to pay estimated taxes, and how can I best calculate the estimated deductions to determine my income?” — one first-time consultant asked on the TurboTax community. The answer: Form 1040-ES is the worksheet, but you don't mail a “return” each quarter — you just pay.

How do I actually pay the IRS each quarter?

The fastest way is IRS Direct Pay: free, straight from your checking or savings account, no sign-in required, and you can change or cancel within two days of a scheduled payment. You choose an estimated-tax payment for tax year 2026, enter the amount, and keep the confirmation number — that is the whole transaction.

Your other options:

• IRS Online Account — requires an ID-verified sign-in, but it shows up to five years of payment history, including every estimated payment. That history is where you check your total at filing time, because nobody sends you a year-end form for estimated payments.
• EFTPS — free, from your bank account, but you have to enroll first.
• Debit card, credit card, or digital wallet — works, but the processor charges a fee.
• Mail — a check with the Form 1040-ES voucher, postmarked by the due date.

One payment covers everything. There's no separate quarterly payment for self-employment tax versus income tax — estimated tax is one combined amount, and the IRS sorts it out when you file.

What happens if I miss a quarterly estimated tax payment?

The penalty is interest, not a fine: it runs at the federal underpayment rate — 7% a year for the quarter that began October 1, 2026 — on each shortfall, for the days it stays unpaid. On $1,000 underpaid, that is about 19 cents a day. It's figured separately for each installment under §6654, and the IRS computes it and bills you — most people never touch Form 2210.

Run the numbers on the $30,000-profit example above. Skip all four $1,296 payments and pay everything with the return on April 15, 2027, and the total penalty works out to roughly $238 on a $5,182 bill — about 4.6%, using the published 2026 rates (6% for the second quarter, 7% for the third and fourth) and assuming the rate holds into early 2027. One payment made 61 days late costs about $13. This is a cost of money, not a catastrophe.

Two real cases put the proportions in perspective. In Fussell v. Commissioner (T.C. Memo. 2025-131), a California software consultant was paid $128,999 of nonemployee compensation for his 2018 tax year, filed no return, and sent in no estimated payments. The court walked through the §6654 math — four installments, each 25% of the smaller of 90% of the year's tax or 100% of the prior year's — and sustained a $1,254 estimated-tax addition. That's about 3% of his $38,662 tax. What actually buried him was not filing and not paying: those two additions came to $8,699 and $8,892 — fourteen times the quarterly penalty. A Tax Court Memo decides one taxpayer's facts, but the shape of it is the lesson: the quarterly penalty is the small one. File on time, pay what you can, and start the installments the day you know you owe.

And in Clark v. Commissioner (T.C. Memo. 2025-13), a 30-year freelancer told the court he simply never makes estimated payments and eats the penalty each year — for his 2019 year, that was $134 on $4,369 of tax, again about 3%. We're not recommending his system. We're telling you the honest size of the problem so you stop losing sleep over it and start paying.

One caution: “I didn't know” is not a waiver ground. The IRS waives this penalty for casualty or disaster situations, or for taxpayers who retired after 62 or became disabled with reasonable cause — not for first-year confusion. The real fix is that each installment's clock stops the day you pay it, so a late start is always better than no start.

How do I turn quarterly taxes into a habit instead of a scramble?

Our standing advice to first-year 1099 workers: sweep 25–30% of every net dollar into a separate tax account the day the money lands — 25% in no-income-tax states, 30% in California, more in an unusually profitable year. Always net, never gross. That single habit makes the four due dates boring, which is the goal. The full system is in our guide on how much to set aside for taxes.

Then pick a rhythm that matches how you get paid. The IRS explicitly allows more than four payments, so weekly or monthly transfers from that tax account are fine — many gig workers pay monthly and treat the quarterly date as a check-in rather than an event. If your income is lumpy — a slow spring and a huge fall — the annualized income installment method on Form 2210 (Schedule AI) lets later, larger payments match when the income actually arrived.
