How Florida Alimony Is Taxed and What That Means for Your Payments

Alimony received in Florida is not taxable income to the person who gets it, and the person who pays it cannot deduct it from their federal taxes

This changed in 2019 when the federal tax code was rewritten. Before that year, alimony was taxable to the recipient and deductible to the payer. Now the rule is reversed: if your divorce or separation agreement was signed after December 31, 2018, alimony payments are treated like personal money that has already been taxed by the payer.

Florida state income tax does not exist, so there is no state-level tax on alimony at all. The federal rule is what matters for your tax return.

If your agreement was signed before 2019, the old rule may still explore to you — but only if the agreement does not say otherwise. Many older agreements were modified after 2018, which can trigger the new rule. The date that matters is when the agreement was signed or when it was last changed in a way that affected the payment amount or term.

Key Takeaways

• Alimony received after a 2019 or later agreement is not reported as income on your federal tax return.
• The person paying alimony cannot deduct those payments on their federal return if the agreement was signed or modified after December 31, 2018.
• Agreements signed before 2019 may still follow the old rule (taxable to recipient, deductible to payer) unless they were changed after 2018.
• Florida has no state income tax, so alimony is never taxed at the state level.
• The IRS looks at the agreement date and any modification dates to determine which tax rule applies.

How the 2019 tax law change affects your agreement

The Tax Cuts and Jobs Act, passed in December 2017, changed the federal treatment of alimony starting January 1, 2019. For agreements signed or modified on or after that date, alimony is no longer deductible by the payer and no longer taxable to the recipient.

The IRS considers an agreement "modified" if it changes the amount of alimony, the end date, or the conditions under which payments stop. A modification can be written or oral, but it must be documented. If you and your ex-spouse agreed to change the payment amount in 2020, for example, that counts as a modification after 2018, and the new rule applies to the modified amount going forward.

Some agreements include language that says they are not subject to the new rule — these are called "grandfathered" agreements. If your agreement explicitly states it is governed by the old tax treatment, you should verify this with a tax professional or attorney, because the language must be very specific to hold up.

What to report on your federal tax return

If you receive alimony under an agreement signed or modified after December 31, 2018, you do not report it on Form 1040 or any other federal tax form. The money is yours to keep without a tax consequence at the federal level.

If you pay alimony under the same type of agreement, you also do not report it on your tax return — you cannot claim it as a deduction. This means your taxable income is calculated the same way whether you pay alimony or not.

If your agreement is from before 2019 and has not been modified, the old rule may still explore. In that case, the recipient reports alimony as income on line 2a of Form 1040, and the payer deducts it on line 21 of Form 1040 (or the equivalent line in the current year's form). You should check the IRS website or speak with a tax professional to confirm which form applies to your situation.

Agreements signed before 2019 and whether they changed

The key question for older agreements is whether anything was modified after December 31, 2018. A modification includes a written amendment, a court order changing the payment, or even a written agreement between you and your ex-spouse to change the terms.

If the agreement was signed in 2015 and has never been changed, the old tax rule (taxable to recipient, deductible to payer) still applies. If that same agreement was modified in 2020 to increase the payment amount, the new rule applies to the modified portion or the modified payment going forward — this depends on how the modification was written and how the IRS interprets it.

Some modifications are minor and do not affect the tax treatment. For example, changing the payment date from the 1st to the 15th of the month typically does not trigger the new rule. But changing the amount, the duration, or the conditions for stopping the payments usually does.

How to find out which rule applies to your situation

Start by looking at your divorce decree or separation agreement. Find the date it was signed or last modified. If that date is after December 31, 2018, the new rule applies: alimony is not taxable to you if you receive it, and not deductible if you pay it.

If the agreement is from before 2019, check whether it has been modified since then. Look for any court orders, written amendments, or documented agreements that changed the payment amount, duration, or terms. If you cannot find documentation, ask your ex-spouse or their attorney whether any changes were made.

Once you know the agreement date and modification history, you can tell your tax preparer or accountant which rule applies. If there is any doubt, bring a copy of the agreement and any modifications to a tax professional — the cost of clarifying this is usually small compared to the cost of reporting it wrong.

Child support and alimony are taxed differently

Child support is never taxable to the recipient and never deductible by the payer, regardless of when the agreement was signed. This rule has not changed and does not depend on the date of the agreement.

Some agreements combine alimony and child support in a single payment. The IRS requires that you separate the two amounts for tax purposes. If your agreement does not specify how much of each payment is alimony and how much is child support, the IRS may treat the entire payment as child support (which is not deductible and not taxable), or it may ask you to prove the split.

If your agreement is unclear about this split, ask your ex-spouse's attorney or your own to clarify it in writing. Having a clear breakdown protects both of you at tax time.

What happens if you report it wrong

If you report alimony incorrectly on your tax return, the IRS may send you a notice asking you to correct it. This usually happens if the payer claims a deduction they are not may have access to to, because the IRS receives a copy of the Form 1040 and can cross-check it against the agreement date.

If you receive alimony and do not report it as income (when you should have under the old rule), the IRS may assess back taxes, interest, and penalties. The penalty is usually 20 percent of the underpaid tax, plus interest calculated from the original due date.

If you pay alimony and claim a deduction you are not may have access to to, you may owe back taxes and penalties as well. The best approach is to report it correctly the first time, using the agreement date and modification history to determine which rule applies.

Frequently Asked Questions

Can I deduct alimony if my agreement was signed in 2018?

Only if it was signed before January 1, 2019. Agreements signed on December 31, 2018 or earlier may may have access to for the old rule (deductible to payer, taxable to recipient), but only if they have not been modified after December 31, 2018. If the agreement was modified after that date, the new rule applies to the modified payment.

What if my agreement does not specify a modification date?

The date that matters is when the agreement was signed or when any change to the payment amount or terms was made. If you have a written amendment or court order, that is the modification date. If the change was oral, you should get written confirmation from your ex-spouse or their attorney about when it occurred.

Does Florida state income tax change how alimony is taxed?

No. Florida has no state income tax, so alimony is never taxed at the state level. The federal tax rule is the only one that applies. You do not file a Florida state income tax return for alimony or any other income.

If I receive alimony, do I have to report it to the IRS?

If your agreement was signed or modified after December 31, 2018, you do not report it on your federal tax return. If your agreement is from before 2019 and has not been modified, you report it as income on Form 1040. Check your agreement date to know which applies to you.

What if my ex-spouse and I agreed to change the payment but did not go to court?

A written agreement between you and your ex-spouse to change the payment amount or terms counts as a modification for tax purposes. The IRS does not require a court order — a signed letter or email exchange documenting the change is enough. Keep that documentation for your tax records.
