Tax already withheld from a W-2 job counts toward your total for the year, so entering it cuts the quarterly payment you actually need to send. Skipping this is the single biggest reason freelancers overpay estimated tax.

The IRS will not charge an underpayment penalty if you pay the smaller of 90 percent of this year's tax or 100 percent of last year's total tax, rising to 110 percent if last year's income was above $150,000. Fill these in and the calculator picks the cheaper legal target.

Quarterly payment schedule
If you are paid on a 1099-NEC or a 1099-K instead of a W-2, nobody withholds tax for you. You are responsible for sending it to the IRS yourself four times a year, and you pay both halves of Social Security and Medicare, the employee half and the half an employer would normally cover.
This self employment tax calculator works out what you actually owe as a freelancer, independent contractor or gig worker, then turns it into the two numbers you can use straight away. The percentage to hold back from every client payment, and the amount to send the IRS each quarter.
A W-2 employee earning $80,000 pays 7.65 percent in FICA. A freelancer with $80,000 of net profit pays 15.3 percent, because there is no employer to split it with. That extra 7.65 percent is roughly $6,100 a year, and it lands on top of ordinary income tax rather than instead of it.
Three things soften the blow and this calculator applies all of them.
Every dollar of legitimate business expense saves you your marginal income tax rate plus 15.3 percent SE tax. For someone in the 22 percent bracket that is roughly 37 cents saved for every dollar spent. The deductions people leave on the table most often:
| Quarter | Income period | Payment due |
|---|---|---|
| Q1 | January 1 to March 31 | April 15, 2026 |
| Q2 | April 1 to May 31 | June 15, 2026 |
| Q3 | June 1 to August 31 | September 15, 2026 |
| Q4 | September 1 to December 31 | January 15, 2027 |
Notice the quarters are not equal. Q2 covers two months and Q3 covers three. An equal quarters schedule still works, but naively dividing by four each calendar quarter can leave you short. If a due date falls on a weekend or a federal holiday it moves to the next business day.
You are protected from the underpayment penalty if your payments for the year total at least the smaller of these two amounts.
The prior year route is the practical one for anyone whose income moves around. If you made $60,000 last year and $150,000 this year, paying 100 percent of last year's tax keeps you penalty free even though you will owe a lot more in April. Enter last year's figures above and the calculator tells you which target is cheaper.
There is also a de minimis rule. If you end up owing less than $1,000 after withholding and credits, there is no penalty at all.
If you or your spouse also has a W-2 job, you can skip quarterly payments entirely by raising the withholding on that job using Form W-4 Step 4c. Withholding counts as paid evenly across the whole year no matter when it actually happens, which means a December adjustment can still fix an underpayment from January. Estimated payments do not get that treatment, so a late estimated payment cannot undo an early shortfall.
The common advice of 25 to 30 percent is only a rough average. In reality it ranges from about 15 percent for a lower earner in a state with no income tax to over 45 percent for a high earner in California. The percentage at the top of this page is worked out from your own numbers, which is far more useful than a rule of thumb.
Take your net profit, which is gross income minus business expenses, multiply it by 92.35 percent, then apply 15.3 percent to the result. The 15.3 percent splits into 12.4 percent Social Security, which stops above $184,500 of net earnings in 2026, and 2.9 percent Medicare, which has no ceiling. Half of the total is then deductible against your income tax.
You can pay it all in April but you will owe an underpayment penalty, charged as interest on the amount you should have paid each quarter. The only exceptions are if you owe under $1,000 after credits, or you had no tax liability at all in the prior year. The penalty is not huge but it is pure waste.
You are charged interest on the shortfall from the date it was due until you pay it. Nothing dramatic happens immediately and there is no separate late filing penalty on estimated payments. Pay as soon as you realise, because the charge accrues daily. If you have a W-2 job, raising withholding there can also cure it.
For most sole proprietors, single member LLCs and partnerships, yes, up to 20 percent of qualified business income. It gets restricted for specified service businesses such as consulting, law, accounting and health once your taxable income passes the threshold, and wage and property limits apply at higher incomes. If that is you, set QBI to not claimed for a conservative estimate and speak to a CPA.
Yes. Any income on a 1099-NEC or 1099-K, and in fact any self employed income even where no form was issued, is business income. Platform commissions and fees are deductible, and for driving work mileage is normally the largest deduction by a wide margin. Track every mile including between deliveries, not just while a passenger or order is in the car.
Self employment tax kicks in once your net earnings reach $400, which is a much lower threshold than people expect. Income tax depends on your total income and the standard deduction, which is $16,100 for a single filer in 2026, so you can often have several thousand dollars of profit with no income tax but still owe SE tax.
Effectively yes, at the same gross figure, because you pay both halves of FICA rather than one. That is why a $60 per hour 1099 contract is not equivalent to a $60 per hour W-2 job. You also lose employer benefits, paid leave and unemployment cover. As a rough guide a 1099 rate needs to be somewhere around 25 to 40 percent higher to match a W-2 offer, depending on the benefits involved.
Yes, they are separate deductions and both are allowed if you genuinely qualify. Mileage covers business driving at the IRS standard rate. The home office deduction needs a space used regularly and exclusively for business, and the simplified method pays $5 per square foot up to 300 square feet. Having a home office can also make more of your driving deductible.
No. A sole proprietor deducts exactly the same expenses on Schedule C without any registration. An LLC provides liability protection and can change how you are taxed if you elect S corporation treatment, but it does not by itself unlock any extra deductions.
The simplest route is IRS Direct Pay on irs.gov, choosing Estimated Tax and the correct tax year. You can also use EFTPS, the IRS2Go app, or post Form 1040-ES with a cheque. State estimated payments go to your own state revenue department and are a completely separate transaction.
Two good options. Use the prior year safe harbor, which fixes your payments at a known amount regardless of what this year does. Or use the annualised income instalment method on Form 2210, which lets you pay in proportion to when you actually earned the money. The second is more work but better if your income is heavily weighted to the end of the year.
In most states yes, and it is a separate payment to your state revenue department with its own form and sometimes different due dates. Nine states have no income tax on earned income, so if you are in one of those you only send federal payments. Check whether your state also has a business or franchise tax on top.

It uses the published 2026 federal brackets and standard deduction, the Social Security wage base, the standard SE tax formula and each state's own 2026 rate schedule, so it is close for a typical sole proprietor. It does not model the alternative minimum tax, net investment income tax, QBI wage and property limits, city income tax, or S corporation salary planning.
