When clients pay you without withholding taxes, part of that money may need to fund federal tax payments during the year. The challenge is larger than picking a percentage: your freelance profit, other income, deductions, credits, and existing withholding all affect the answer. Use a simple reserve habit to protect cash, then use an actual tax projection to determine payments.
Check whether estimated payments are needed
Individuals generally need estimated payments when they expect to owe at least $1,000 after withholding and refundable credits, and those prepayments are below the applicable required amount. The general comparison uses 90% of current-year tax or 100% of prior-year tax, whichever is smaller. Higher prior-year income can raise that second percentage to 110%. The prior-year return generally must cover twelve months.
Those percentages compare tax amounts, not business revenue. Start with your prior return and a current income projection rather than multiplying this year’s invoices by last year’s tax bracket.
Include more than income tax
Estimated payments can cover self-employment tax as well as federal income tax. If you also earn wages, additional employer withholding may help cover the total requirement. Your household’s full situation matters; a freelance-only calculation cannot determine the whole return.
Create a worksheet that separates projected annual profit, other income, withholding, payments already made, and remaining cash reserved. Revisit it when a major contract starts or ends. Mark estimates clearly so a hoped-for project does not quietly become assumed income.
Use the dates for the year you are planning
For calendar-year 2026 estimated payments, the standard dates are April 15, June 15, and September 15, 2026, followed by January 15, 2027. These are 2026 planning dates, separate from filing a 2025 return. Special rules and applicable disaster relief can change an individual deadline.
The payment periods are not four equal calendar quarters. Put reminders before the relevant deadlines and save payment confirmations with the selected tax year and payment type. A transfer into your own savings account is a reserve, not a payment to the IRS.
Adjust when income is uneven
An annualized income installment method may help determine payments when earnings arrive unevenly. Underpayment penalties can depend on the timing of payments, so sending a large amount late in the year does not automatically resolve earlier shortfalls.
Suppose a writer collects little during the first half of the year and receives a large project payment in September. Preserve monthly income and expense totals. Those records make it possible to evaluate the appropriate installment calculation instead of guessing that each payment must equal one quarter of the final annual tax.
Keep your reserve and payment calculation connected
Choose a workable saving routine, such as transferring part of each client payment to a dedicated tax reserve. Then compare the reserve against a reviewed projection. The saving percentage may need to change as profitability or household income changes.
Before each payment, reconcile what has actually been paid and retain the confirmation. Bring your open questions to a qualified preparer, especially after a sharp income change. An online illustration can help you plan cash; the relevant IRS worksheet and your full tax information determine the appropriate payment.
THE IDEA TO TAKE WITH YOU
Save consistently, project the complete tax picture, and verify the amount and timing of actual IRS payments.
