What is Estimated Tax?
Quarterly tax payments made by freelancers to cover income and self-employment tax when no employer withholding applies.
Definition
Estimated tax is the method the IRS uses to collect income and self-employment taxes from freelancers, independent contractors, and others who do not have taxes withheld from their income by an employer. Instead of a single annual payment, estimated tax requires four quarterly payments throughout the year — on April 15, June 15, September 15, and January 15. Each quarterly payment is intended to cover roughly 25% of your expected annual tax liability.
Who Must Pay Estimated Tax
Any freelancer or self-employed individual who expects to owe $1,000 or more in federal taxes for the year must make estimated tax payments. This includes sole proprietors, partners in partnerships, S-corporation shareholders, and LLC members. Even if you also have W-2 income, if your freelance income results in an additional tax liability of $1,000 or more after withholding, you may owe estimated taxes. State taxes follow similar rules and must typically be paid quarterly as well.
How to Calculate Quarterly Payments
The most straightforward method is to estimate your annual freelance income, subtract your expected business expenses and deductions, calculate the resulting taxable income and tax liability (including self-employment tax), and divide by four. A simpler shortcut used by many freelancers: set aside 25–30% of every freelance payment received. This is a rough guideline — your actual rate depends on your total income and bracket. Using last year's tax return as a baseline is a practical starting point, adjusted for any expected changes in income.
Avoiding Underpayment Penalties
The IRS charges penalties if you underpay estimated taxes, unless you meet one of the safe harbor exceptions. The basic safe harbor rule: you will not be penalized if you pay at least 100% of last year's total tax liability (or 110% if your adjusted gross income was over $150,000) in estimated payments throughout the year. This means even if you owe more than last year, you can avoid penalties by paying last year's amount in quarterly installments. However, you will still owe the full amount when you file your return.
How to Pay Estimated Taxes
Federal estimated taxes can be paid through the IRS Direct Pay website (free, immediate), the Electronic Federal Tax Payment System (EFTPS, requires enrollment), or by mailing a check with Form 1040-ES. State estimated taxes are paid through your state's Department of Revenue website or equivalent. Most freelancers find it easiest to set up a separate savings account and transfer 30% of each payment they receive into it throughout the year — then use those funds to make quarterly payments.
