Child Support vs. Alimony: Tax Differences
Child support and alimony are both common post-divorce payments, but they're treated very differently for tax purposes.
Child Support vs. Alimony: Tax Treatment
Alimony
Pre-2019 Divorces
- Payer: Deducted from AGI (above-the-line deduction)
- Recipient: Included as taxable income
Post-2018 Divorces
- Payer: NOT deductible
- Recipient: NOT taxable
If a pre-2019 divorce agreement is modified after 2018, it could be treated under the new rules if both parties agree.
Child Support
Regardless of when the divorce occurred:
- Payer: NOT deductible
- Recipient: NOT taxable income
Why This Matters for Negotiations
In divorces prior to 2019, designating payments as alimony rather than child support benefited both parties (payer got a deduction, recipient received more tax-efficient income at a lower rate).
Post-2018, there's no longer an incentive to characterize payments as alimony.
Dependency Exemptions
Child support payer cannot claim the child as a dependent unless the custodial parent signs Form 8332 releasing the exemption.
Lump Sum vs. Periodic Payments
A one-time property settlement is generally not alimony and not taxable/deductible.
Navigating divorce taxes? The rules depend heavily on when your divorce was finalized.
