Employer Adoption Assistance

Employer adoption assistance is money an employer pays or reimburses for an employee's qualified adoption expenses under a written plan, which Internal Revenue Code section 137 excludes from the employee's gross income up to an annual limit. Section 137(c) requires the arrangement to be "a separate written plan of an employer for the exclusive benefit of such employer's employees" that provides adoption assistance and meets requirements similar to several of the educational assistance rules in section 127(b), which in practice means it cannot discriminate in favor of highly compensated employees.

The Code heads section 137 "Adoption assistance programs" and Publication 15-B heads its section simply "Adoption Assistance". This entry adds the word employer for a reason worth knowing: "adoption assistance" is also the name of the state subsidy that Title IV-E of the Social Security Act, at 42 U.S.C. section 673, authorizes states to pay to the adoptive parents of children with special needs under an "adoption assistance agreement". The two are unrelated. One is a workplace benefit and a tax exclusion; the other is an ongoing public payment negotiated with a state child welfare agency.

The exclusion and the credit are two provisions, not one, and the difference is where most of the confusion lives. Section 23 gives a tax credit for qualified adoption expenses the family paid. Section 137 excludes from income what an employer paid. They carry the same dollar figures because section 137(f) indexes from the same 2001 base as the credit does, which makes them look like one rule stated twice. They are not, and a family can benefit from both in the same adoption.

What they cannot do is cover the same expense twice, and the mechanism is worth naming precisely. Section 23(d)(1)(D) defines a qualified adoption expense as one "not reimbursed under an employer program or otherwise", so a dollar your employer reimbursed is simply not an eligible expense for the credit. Section 137(d) borrows section 23(d)'s definition for the exclusion but adds "determined without regard to reimbursements under this section", so that the reimbursement does not disqualify itself. The Instructions for Form 8839 turn this into an ordering rule: complete Part III, the exclusion, before you can figure the credit in Part II.

The payroll-tax asymmetry is the page's most useful practical fact. Publication 15-B states it in two sentences: "You must exclude all payments or reimbursements you make under an adoption assistance program for an employee's qualified adoption expenses from the employee's wages subject to federal income tax withholding. However, you can't exclude these payments from wages subject to social security, Medicare, and FUTA taxes." So the benefit behaves unlike a pre-tax health premium, which escapes both, and more like a traditional 401(k) deferral, which escapes income tax only. Anyone sizing the benefit at their full combined rate has overstated it by the Social Security and Medicare component.

Everything is reported, whether or not it is excludable. The employer reports all qualifying adoption expenses paid or reimbursed for the year in box 12 of the Form W-2 using code T, including amounts above the exclusion. Seeing a code T figure larger than the exclusion is not an error; it is the form doing what it is supposed to do, and Form 8839 is where the excludable and taxable halves get separated.

The special-needs rule is a genuine departure from how the rest of the section works. Section 137(a)(2) provides that where the adoption of a child with special needs becomes final during the year, qualified adoption expenses for that year are increased by the excess of the statutory amount over the actual expenses incurred for that adoption across all years. In plain terms, the full amount is treated as spent even if it was not. The Instructions for Form 8839 confirm that the exclusion "may be available, even if you or your employer didn't pay any qualified adoption expenses, provided the employer has a written qualified adoption assistance program". A child with special needs is a defined term under section 23(d)(3) and turns on a state or Indian tribal government determination, not on a medical diagnosis.

The income limit is a proportional phase-out, not a cliff. Section 137(b)(2) reduces the excludable amount by the fraction that the excess of modified adjusted gross income over the phase-out start bears to the width of the phase-out range. At the top of the range the exclusion is gone entirely; in the middle, part of it survives.

Two edge cases worth knowing before you rely on the benefit. First, a more-than-2-percent shareholder of an S corporation cannot use the exclusion, because the Code treats such a shareholder as a partner for fringe benefit purposes. Second, for a foreign adoption, the Instructions for Form 8839 provide that employer payments made in a year before the adoption becomes final must be included in income in the year of payment, with the exclusion taken by adjustment on the return for the year the adoption becomes final. Because the employer is not required to withhold income tax on those payments, the instructions warn that withholding may not be enough to cover the tax in that first year.

1. The employer adopts a separate written plan meeting section 137(c), including the requirement that it not favor highly compensated employees.

2. The employee incurs qualified adoption expenses and submits them under the plan.

3. The employer pays or reimburses them and excludes the amount from wages subject to federal income tax withholding, but includes it in Social Security, Medicare and federal unemployment wages.

4. The employer reports the full amount in box 12, code T of the Form W-2, whether or not all of it is excludable.

5. The employee files Form 8839, completing Part III first to compute the excludable amount, then Part II to compute the credit on whatever expenses the employer did not reimburse.

A hypothetical illustration. Dana adopts a child and incurs $20,000 of qualified adoption expenses. Her employer's plan reimburses $12,000 of them. Her modified adjusted gross income is well below the phase-out range, and the reimbursement is under the annual exclusion limit, so the whole $12,000 is excludable.

What that is worth, and what it is not worth: the $12,000 is kept out of her wages for income tax withholding, but it stays in her Social Security and Medicare wages. At the combined 7.65 percent employee rate, that is 12,000 × 0.0765 = $918 of payroll tax she still pays on money she never sees as cash.

The credit side then works on what the employer did not cover. $20,000 − $12,000 = $8,000 of expenses were not reimbursed under an employer program, so they remain qualified adoption expenses under section 23(d)(1)(D) and can support the credit, subject to the credit's own limit, phase-out and timing rules on the adoption tax credit entry. Both provisions applied to one adoption; neither applied to the same dollar. All figures are illustrative.

Pros

• The exclusion is worth its face value in income tax, on a benefit most employees would otherwise pay for entirely with after-tax money.
• It stacks with the adoption tax credit across one adoption, as long as no single expense is counted for both.
• For a special-needs adoption finalized in the year, the full statutory amount can be excluded whether or not that much was actually spent.
• The plan requirements bar discrimination in favor of highly compensated employees, so where the benefit exists it is broadly available.

Cons

• It does not escape Social Security, Medicare or federal unemployment tax, so the saving is smaller than a pre-tax health premium of the same size.
• The exclusion phases out entirely above a modified adjusted gross income threshold, which reaches two-earner households more often than the figure suggests.
• A more-than-2-percent S corporation shareholder is shut out of it.
• For a foreign adoption not yet final, the payment is taxable in the year received and the exclusion has to be recovered later, with no withholding to cover the interim tax.
• The benefit exists only if the employer has adopted a written plan; nothing requires one.
