Annualized Income Method: Uneven Freelance Income

Checked October 17, 2026 · Educational summary

General information, not tax, legal or financial advice. We are not the IRS. Check IRS.gov or a qualified tax professional. Sources read on October 17, 2026. Dates for 2027 and later are expected. Examples use made-up numbers. This page contains no affiliate links.

Publication 505 says that if you don't receive income evenly through the year, your required estimated payment for one or more periods may be less than under the regular method (annual tax divided by 4). The annualized income installment method annualizes your tax at the end of each period based on a reasonable estimate of income, deductions and other items from January 1 through the end of that period.

How it works (per Pub. 505)

• Complete the 2026 Estimated Tax Worksheet through line 14b, then the 2026 Annualized Estimated Tax Worksheet (Worksheet 2-9).
• The periods build: each includes all earlier periods. After each period ends, complete that column to figure the payment due.
• Use the result on line 32 of Worksheet 2-9 for your payments and vouchers.
• If you have self-employment income, complete Section B first and use line 41 for expected AGI in Section A, line 1.
• You must file Form 2210 with your 2026 return if you use this method (see Schedule AI in the Form 2210 instructions).

When the regular method fits

The regular installment method (divide the annual amount by 4) is for when income is "basically the same throughout the year."

Made-up illustration

A seasonal business earns most of its income in summer. Under the regular method a first-quarter payment of one quarter of the annual tax is required; under the annualized method the first-period required amount reflects only income through March 31, so it can be lower. Actual amounts depend on the worksheet.
