Updated October 19, 2026. Quick answer: Part III of Form 8839 figures how much employer-provided adoption benefit can be left out of income, on lines 19 through 31. For 2025 the limit is $17,280 per child, the benefits should appear in box 12 of Form W-2 with code T, and any amount that cannot be excluded flows to line 1f of the return.

What Part III is for
The instructions describe the purpose: “Use Form 8839, Part III, to figure the employer-provided adoption benefits you can exclude from your income on Form 1040, 1040-SR, or 1040-NR, line 1f.” The plan matters: “A qualified adoption assistance program is a separate written plan set up by an employer to provide adoption assistance to its employees.”
The benefit itself is described this way: “In most cases, employer-provided adoption benefits are amounts your employer paid directly to either you or a third party for qualified adoption expenses under a qualified adoption assistance program.” “Employer-provided adoption benefits should be shown in box 12 of your Form(s) W-2 with code T.”
Order matters when the credit is also claimed. The instructions say “you must complete Form 8839, Part III, before you can figure the credit, if any, in Part II.” The credit side is covered on the Form 8839 Part II page.
Lines 19 to 24: the cap and the benefits received
Line 19 states “The maximum amount that can be excluded from income for employer-provided adoption benefits is $17,280 per child.” “If you and another person (other than your spouse if filing jointly) each received employer-provided adoption benefits in connection with the adoption of the same eligible child, the $17,280 limit must be divided between the two of you.”
Line 20 covers earlier years: “If you received employer-provided adoption benefits in a prior year for the same child, enter on line 20 the total of the amounts shown on lines 20 and 24 (or corresponding lines) of the last Form 8839 you filed for the child.” Line 21 is “Subtract line 20 from line 19”. Line 22 is “Employer-provided adoption benefits you received in 2025.”
Line 24 is the smaller of lines 21 and 22, with an exception printed on the form: “But if the child was a child with special needs and the adoption became final in 2025, enter the amount from line 21”. The instructions condition that on the plan: “If your employer has no qualified adoption assistance program, you must enter the smaller of line 21 or line 22.”
Lines 25 to 30: the income phase-out
Line 25 uses its own worksheet. “Use the Modified Adjusted Gross Income (MAGI) Worksheet to figure your modified adjusted gross income.” Line 26 asks “Is line 25 more than $259,190?” and the answer path begins with “No. Skip lines 26 and 27, and enter -0- on line 28.”
Line 27 is a decimal: “Divide line 26 by $40,000. Enter the result as a decimal (rounded to at least three places). Do not enter more than 1.000”. Line 28 is “Multiply each amount on line 24 by line 27”. Line 29 is “Excluded benefits. Subtract line 28 from line 24”.
The instructions give a caution about this MAGI: “Your MAGI for the adoption credit may not be the same as the MAGI figured in the above worksheet.”
Line 31 and what happens to taxable benefits
Line 31 is titled “Taxable benefits.” The first path reads “No. Subtract line 30 from line 23.” “Also, include this amount, if more than zero, on line 1f of Form 1040, 1040-SR, or 1040-NR.”
The instructions use a reimbursement example. “Under a qualified adoption assistance program, your employer reimbursed you for $4,000 of those expenses.” “The $4,000 reimbursement may be excluded from your income.”
Foreign child timing and withholding
A foreign adoption that is not final changes the treatment. “If your employer makes adoption assistance payments in a year before the adoption of a foreign child is final, you must include the payments in your income in the year of the payment.”
The instructions also say “Your employer isn’t required to withhold income tax on payments for qualifying expenses under an adoption assistance program.”

Common mistakes
- Assuming every employer benefit is excluded. Line 31 sends taxable amounts to “line 1f of Form 1040, 1040-SR, or 1040-NR.”
- Skipping Part III first. The instructions say “you must complete Form 8839, Part III, before you can figure the credit, if any, in Part II.”
- Assuming no plan is needed in the special needs case. The instructions say “only if your employer has a qualified adoption assistance program”
- Assuming withholding covers a foreign adoption that is not final. The instructions warn that “your withholding may not be enough to cover the tax on those payments.”
