Do I Have to Pay Quarterly Taxes? The $1,000 Rule Explained

You generally must pay 2026 quarterly estimated tax only if two things are true: you expect to owe at least $1,000 after withholding and refundable credits, and your withholding will be less than the smaller of 90% of your 2026 tax or 100% (or 110%) of your 2025 tax. Zero 2025 tax is a full exception.

Last reviewed September 23, 2026

"Do I have to pay quarterly taxes?" is one of the most common questions freelancers and side-hustlers ask. The answer is a two-part test from the 2026 Form 1040-ES, plus one exception. Once you see how the parts fit together, you can usually answer it for yourself in a few minutes.

What is the $1,000 rule for estimated taxes?

The $1,000 figure is the first half of the test. Under the 2026 Form 1040-ES, you generally must pay estimated tax for 2026 if both of these apply:

1. You expect to owe at least $1,000 in federal tax for 2026, after subtracting your withholding and refundable credits.
2. Your withholding and refundable credits will be less than the smaller of:
   • 90% of the tax on your 2026 return, or
   • 100% of the tax on your 2025 return (110% if your 2025 AGI was more than $150,000, or more than $75,000 if you file married filing separately for 2026). The 2025 return must cover a full 12 months.

The same $1,000 line appears in the penalty rules. IRC §6654(e)(1) says there is no underpayment penalty if the tax on your return, less withholding, is under $1,000.

"Tax" means your total federal tax. For self-employed people that includes self-employment tax (15.3% on 92.35% of net profit, with the Social Security part capped at the 2026 wage base of $184,500). It is easy to cross $1,000 on SE tax alone. A single freelancer with $50,000 of profit and no other income would owe about $7,065 in SE tax before any income tax.

Is there an exception if I owed nothing last year?

Yes, and it is a full one. You don't have to pay 2026 estimated tax if:

• you were a US citizen or resident alien for all of 2025, and
• you had no tax liability for the full 12-month 2025 tax year.

The 1040-ES says you had no tax liability if your total tax was zero or you didn't have to file a return. Note that a refund is not the same as zero tax. If tax was withheld from a job and you got some of it back, your total tax may still have been more than zero.

This exception matters most for people who are new to working, including many first-year freelancers. We cover that case in First Year Freelancing: How to Handle Estimated Taxes.

How does the test work with a W-2 job and a side business?

Withholding from a job counts toward both parts of the test. Here are three single filers, each with a $60,000 W-2 job and $6,000 of federal tax withheld. We ran each one through our Quarterly Estimated Tax Calculator using the standard deduction.

The arithmetic for C: 90% × $8,028.34 = $7,225.50. Subtract $6,000 of withholding and $1,225.50 is left. Divided over four installments, that is $306.38 each.

Person B shows why the second test matters. B will owe about $2,028 when they file. That is over $1,000, but their withholding meets the prior-year safe harbor, so estimated payments are generally not required and no penalty should apply. They still need to have the $2,028 ready by April 15, 2027.

What if I'm a full-time freelancer with no withholding?

Then the first test is usually the one that decides it. With no withholding, everything you owe counts toward the $1,000. A few 2026 examples (single, profit only, standard deduction):

The $10,000 row is all self-employment tax: 15.3% × $9,235 of net earnings ($10,000 × 92.35%) = $1,412.96. There is no income tax because the $16,100 standard deduction covers the rest. Even a modest side business can pass $1,000 through SE tax alone.

Unless the zero-tax exception applies, most full-time freelancers need to pay. How much depends on the safe harbor. See Estimated Tax Safe Harbor: 100% vs 110% Rule.

Can I avoid quarterly payments by changing my withholding?

Often, yes, if you or your spouse (on a joint return) has a W-2 job. The 2026 Form 1040-ES suggests filing a new Form W-4 to have more tax taken out of your pay, and points to the IRS Tax Withholding Estimator.

There is also a timing advantage. Under IRC §6654(g), withholding is generally treated as paid in equal parts on the four due dates, whatever the date it was actually withheld. So extra withholding in October, November or December can generally cover earlier quarters. Estimated payments count only from the day you make them.

What happens if I should have paid and didn't?

The IRS may charge an underpayment penalty. It works like interest on each late installment, at the IRS underpayment rate. That rate is 7% a year for October 1 to December 31, 2026 (IR-2026-98). You figure it on Form 2210. As of September 23, 2026, three of the four 2026 due dates have passed. The last one is January 15, 2027. Paying what you can now generally reduces the penalty. The full rules are in our pillar guide to quarterly estimated taxes.

If your records are behind and you're not sure what your profit is, that's the first thing to fix. RAHA's bookkeeping team can get your numbers current and work out your quarterly payments with you. The Bookkeeping + Quarterly Estimates service is a fixed price, quoted upfront.

Frequently asked questions

Is the $1,000 threshold before or after withholding?

After. You compare the tax you expect to owe with your withholding and refundable credits already subtracted. If what's left is under $1,000, estimated payments are generally not required.

Does self-employment tax count toward the $1,000?

Yes. The test uses your total tax, which includes self-employment tax as well as income tax.

I only started freelancing in the fall. Do I owe for the earlier quarters?

Maybe not. If a large change after March 31 means you need to start paying, the 2026 Form 1040-ES points to the annualized income installment method (Form 2210, Schedule AI). It may lower or remove the required payment for periods before your income started.

Do married couples apply the $1,000 rule jointly?

If you file jointly, the test applies to your joint tax and joint withholding. You can make joint estimated payments, with some exceptions listed in the 1040-ES (for example, if either spouse is a nonresident alien).

Do I need to file anything if I don't have to pay estimated tax?

No separate filing is needed. You report your income and pay any balance with your 2026 return, due April 15, 2027.

Does my state follow the same $1,000 rule?

Not necessarily. Many states with a personal income tax set their own thresholds and due dates. Check your state tax agency's estimated tax instructions. Our calculator covers federal tax only.
