The Critical Tax Law Change: Pre-2019 vs. Post-2019

The Tax Cuts and Jobs Act of 2017 (TCJA) fundamentally changed the tax treatment of alimony for all agreements finalized after December 31, 2018.

✅

The Old Rule (Pre-2019 Agreements)

For agreements executed on or before Dec 31, 2018, alimony is **deductible** by the person paying it and is considered **taxable income** for the person receiving it.

❌

The New Rule (Post-2018 Agreements)

For agreements executed on or after Jan 1, 2019, alimony is **not deductible** by the payor. Consequently, it is **not considered taxable income** for the recipient.

Alimony Tax Rules: Frequently Asked Questions

The change was part of the Tax Cuts and Jobs Act of 2017 (TCJA). The primary goal was to simplify the tax code and increase federal tax revenue. By removing the deduction, the government no longer loses the tax revenue from the higher-earning payor's tax bracket.

If you have a pre-2019 divorce agreement and it is modified after 2018, the original tax rules (deductible/taxable) generally still apply. However, if the modification explicitly states that the new tax rules should apply, then the payments would become non-deductible. It is crucial to consult a tax professional in this scenario.

No. The tax rules for child support have not changed. Child support is not, and has never been, tax-deductible for the payor or considered taxable income for the recipient. The TCJA changes only apply to alimony (spousal support).
