What is the adoption tax credit?

The federal adoption tax credit is a tax benefit for eligible adoptions and qualified expenses, but expenses for adopting your spouse's child are excluded. An ordinary stepparent adoption of your spouse's child therefore does not qualify for this credit.

The IRS sets eligible-child, expense, income and filing requirements. Credit amounts and income limits depend on the tax year; use the IRS guidance for the return you are preparing rather than treating an old dollar amount as current.

Three separate questions matter:

• Is this adoption eligible? The spouse-child exclusion applies even if you pay court or document preparation fees.
• Is the expense eligible? For an otherwise eligible adoption, the expense rules and any reimbursement need their own review.
• Does your return qualify? Your tax preparer can assess the tax-year filing and income requirements.

Unmarried partners need a separate analysis. The IRS identifies a possible route for registered domestic partners in states permitting second-parent adoption, subject to the other eligibility conditions. This does not mean every unmarried partner's adoption qualifies.

A dependent claim or another child-related credit is a different issue. Our dependent-tax answer explains why adoption is not automatically required for a stepchild to meet the relationship test.

For planning, our stepparent adoption credit answer distinguishes the document budget from tax eligibility. We prepare adoption documents; a qualified tax professional can apply the tax rules to your return.
