Quick Answer
For divorces finalized before 2019, alimony payments are deductible as an above-the-line deduction even when taking the standard deduction. However, for divorces after December 31, 2018, alimony payments are not deductible at all. In 2026, this affects roughly 600,000 taxpayers with pre-2019 divorce agreements.

Best for taxpayers paying alimony under divorce agreements executed before January 1, 2019
Yes, but only for pre-2019 divorce agreements
Alimony deductibility depends entirely on when your divorce was finalized. If your divorce agreement was executed before January 1, 2019, alimony payments are deductible as an above-the-line deduction on Schedule 1, Line 18. This works perfectly with the standard deduction because it reduces your adjusted gross income (AGI) before you choose between standard ($15,000 for single filers in 2026) or itemized deductions.
Key rule: According to IRS Publication 504, alimony paid under pre-2019 agreements remains deductible for the life of the agreement, even though the Tax Cuts and Jobs Act eliminated the deduction for new agreements.
Example: Executive paying $36,000 annual alimony
Let's say you're divorced in 2017 and pay $3,000/month ($36,000/year) in alimony under a pre-2019 agreement:
2026 Tax Impact:
Tax savings: In the 22% bracket, the $36,000 alimony deduction saves you $7,920 in federal taxes annually — regardless of whether you itemize.
Requirements for the deduction (pre-2019 agreements only)
To qualify for the alimony deduction, payments must meet all these requirements:
Comparison: Pre-2019 vs. Post-2018 divorce tax treatment
*Pre-2019 agreements modified after 2018 may lose deductibility if modification specifically references the TCJA changes.
Special situations and planning opportunities
Modification of pre-2019 agreements: Be extremely careful when modifying alimony terms. If your modification specifically references the Tax Cuts and Jobs Act or the elimination of the alimony deduction, you could lose the deductibility of all payments going forward.
Temporary vs. permanent alimony: Both types are deductible if they meet the requirements above. Lump-sum settlements generally don't qualify unless structured as periodic payments.
State tax considerations: Most states follow federal treatment, but some (like California) have different rules. Check your state's conformity with federal alimony deduction rules.
What you should do
1. Verify your divorce date: If finalized before January 1, 2019, you can likely deduct payments
2. Review your agreement language: Ensure payments meet all IRS requirements
3. Keep detailed records: Document all payments with dates, amounts, and methods
4. Coordinate with your ex-spouse: They must report as income for your deduction to be valid
5. Use our return scanner to ensure you're claiming this valuable above-the-line deduction
Red flag: If you're paying alimony but your ex-spouse isn't reporting it as income, the IRS may disallow your deduction and assess penalties.
Key takeaway: Pre-2019 alimony payments can save $5,000-10,000+ annually in taxes when combined with the standard deduction. Post-2018 divorces get no federal alimony deduction regardless of filing method.

Key Takeaway: Alimony under pre-2019 agreements is deductible above-the-line with standard deduction, saving thousands annually. Post-2018 agreements offer no federal deduction.
Alimony deduction treatment based on divorce agreement date and tax filing method
| Divorce Date | Alimony Deductible? | Works with Standard Deduction? | Annual Tax Savings (22% bracket, $30k alimony) |
|---|---|---|---|
| Before 2019 | Yes (above-the-line) | Yes | $6,600 |
| 2019 or later | No | Not applicable | $0 |
| Pre-2019, modified after 2018 | Depends on terms | If deductible, yes | $0 to $6,600 |

Best for high-income taxpayers with substantial alimony obligations who typically itemize
For high earners, alimony deduction provides massive AGI reduction
If you're in the top tax brackets and paying substantial alimony under a pre-2019 agreement, the above-the-line alimony deduction is incredibly valuable because it reduces AGI before other calculations.
Strategic tax benefit: High-income taxpayers typically itemize anyway, but the alimony deduction reduces AGI, which:
Example: Attorney paying $60,000 annual alimony
With $300,000 income and $60,000 alimony:
Estate planning consideration
For high earners, consider the interaction between alimony obligations and estate planning. Alimony typically terminates at death, but the tax savings during your lifetime can be substantial enough to affect insurance and estate planning decisions.
Key takeaway: High earners with pre-2019 alimony get both the above-the-line deduction and itemized deductions, potentially saving $20,000+ annually in taxes.
Key Takeaway: High-income taxpayers can stack alimony deductions with itemizing, creating substantial tax savings and helping avoid high-income penalties.

Best for taxpayers divorced after 2018 who need to understand the current rules
Unfortunately, post-2018 divorces get no alimony deduction
If your divorce was finalized on or after January 1, 2019, alimony payments are not deductible — period. This was a major change in the Tax Cuts and Jobs Act that affects all new divorce agreements.
The tax burden shift: Under current law:
Planning around the loss: Since you can't deduct alimony, consider:
Exception: Modifications of pre-2019 agreements
There's one narrow exception: If you had a pre-2019 agreement that you're modifying, you might preserve deductibility if the modification doesn't specifically reference the TCJA changes. However, this is complex and requires careful legal drafting.
Standard vs. itemized still matters
Even without alimony deductibility, you should still optimize your standard vs. itemized decision based on your other expenses (mortgage interest, state taxes, charity, etc.).
Key takeaway: Post-2018 divorces cannot deduct alimony payments regardless of filing method. Focus on other tax-reduction strategies instead.
Key Takeaway: Divorces finalized after 2018 cannot deduct alimony payments under any circumstances — a costly change affecting thousands of taxpayers annually.
