If you earn income that isn’t subject to withholding, from self-employment, freelancing, investments, or a business, the IRS expects you to pay tax on it as you earn it, through quarterly estimated tax payments.
Who has to pay
Individuals generally need estimated payments when they expect to owe at least $1,000 after withholding and refundable credits and expect those payments and credits to be less than the applicable safe-harbor amount. Corporations use different rules. Review your facts under IRS Publication 505.
How much to pay
The general individual safe-harbor comparison is the smaller of:
- 90% of the current year’s tax liability, or
- 100% of the prior year’s tax, provided that return covered 12 months. Higher-income taxpayers generally substitute 110%; the threshold is based on prior-year AGI and differs for married filing separately.
Timing matters: sufficient total payments can still leave an installment-period underpayment. Farming, fishing, uneven income, casualty/disaster, retirement/disability, and other exceptions or waiver rules may change the result. See the IRS underpayment penalty guidance.
The schedule
See our 2026 estimated-tax calendar for current dates. The statutory payment periods are not evenly spaced.
Tips to stay ahead
- Set aside a percentage of every payment you receive (many freelancers reserve 25-30%).
- Recalculate mid-year if your income changes significantly.
- Pay electronically through IRS Direct Pay or EFTPS for instant confirmation.

Prepare a projection that reflects your household
Gather current profit figures, wages from other work, your spouse's income if relevant, withholding, and payments already made. Keep the payment confirmations with the tax year and payment type selected. When income changes, bring the new information to your preparer instead of reusing the same amount without review. A freelancer's payment plan should reflect the full return, not just one platform's revenue.
General educational information, not an individual tax opinion. The applicable year, jurisdiction, and facts must be reviewed before acting.
