Tax Mistakes to Avoid in an Alabama Divorce Settlement

The Tax Changes Most People Miss

Divorce settlements involve tax rules that do not come up in normal financial life. Most people learn about them only when the mistake has already been made — and by then, the property division is locked into a final decree that cannot be reopened just because you overlooked a tax consequence.

The 2017 Tax Cuts and Jobs Act fundamentally changed the tax treatment of alimony for any agreement executed after January 1, 2019. Before the change, alimony was deductible by the payer and taxable to the recipient. After the change, alimony is tax-neutral — no deduction, no income recognition. Alabama state tax law conforms to the federal rule under Alabama Code Section 40-18-15(a)(17).

This change means the old strategy of structuring a larger alimony payment (benefiting the payer through deductions) no longer works. For divorces finalized after 2018, alimony is a straight cash transfer with no tax leverage for either party. If you are reading older divorce guides or receiving advice based on pre-2019 rules, the tax analysis is wrong.

For agreements executed before December 31, 2018, the old rules still apply. But if you modify a pre-2019 agreement and the modification explicitly states that the post-TCJA rules apply, the tax treatment switches. Routine modifications to the amount or duration do not trigger the switch — the parties must affirmatively elect the new treatment.

Filing Status Traps

Your marital status as of December 31 determines your filing status for the entire year. If your divorce is finalized on December 30, you file as single (or head of household if you qualify) for the full year — even if you were married for the preceding 364 days.

This timing matters because the tax brackets for married filing jointly are significantly wider than for single filers. A couple with combined income of $180,000 pays substantially less tax filing jointly than each spouse pays individually on $90,000. If your divorce will be finalized near year-end, it may be worth coordinating the timing with your spouse to optimize the joint filing benefit for one more year — assuming you can agree on splitting the tax savings equitably.

If you are separated but not yet divorced as of December 31, you have options. You can file married filing jointly (requires both spouses' agreement and shared liability for the return), married filing separately (no cooperation needed, but narrower brackets and phase-out of many credits), or head of household (if you maintained a home for a dependent child for more than half the year and lived apart from your spouse for the last six months).

Head of household status provides wider brackets than married filing separately and does not require your spouse's cooperation. If you qualify, it is almost always the better option during the separation period.

Retirement Account Withdrawal Penalties

Retirement accounts divided in divorce follow specific rules to avoid taxes and penalties — and getting the procedure wrong is irreversible.

For employer-sponsored plans (401(k), 403(b), pension), a Qualified Domestic Relations Order allows a tax-free transfer to the receiving spouse's own retirement account. Without a QDRO, any distribution is treated as a taxable withdrawal and may trigger the 10 percent early withdrawal penalty if the account owner is under 59½.

One exception: under IRC Section 72(t)(2)(C), distributions from a 401(k) or 403(b) made to an alternate payee under a QDRO are exempt from the 10 percent early withdrawal penalty, even if the recipient is under 59½. This exception applies only to employer-sponsored plans and only to the initial QDRO-directed distribution. If the alternate payee rolls the funds into their own IRA and later withdraws before 59½, the penalty applies.

For IRAs, there is no QDRO. The division is executed as a "transfer incident to divorce" — a direct trustee-to-trustee transfer authorized by the divorce decree. The decree must explicitly name the IRA, the custodian, and the amount or percentage to be transferred. If the receiving spouse simply withdraws funds from the IRA rather than executing a proper transfer, the full amount is taxable and potentially penalized.

The Cost Basis Transfer

Under IRC Section 1041, all property transfers between spouses incident to divorce are tax-free. But "tax-free" means tax-deferred — the receiving spouse inherits the original cost basis.

This matters most for appreciated assets:

• Stock or brokerage accounts: If your spouse purchased stock at $20 per share and it is now worth $100 per share, you inherit the $20 basis. When you sell, you owe capital gains tax on $80 per share.
• Real estate: If you receive the marital home in the divorce, your cost basis is the original purchase price (plus improvements), not the current market value. When you eventually sell, your gain is measured from that original basis.
• Business interests: If you receive a share of a business, your basis is whatever your spouse's basis was — often the original capital contribution, which could be nominal.

The practical impact: two assets with the same face value can have dramatically different after-tax values. A $100,000 stock portfolio with a $20,000 basis carries an $80,000 embedded gain — at a 15 percent capital gains rate, that is $12,000 in future taxes. A $100,000 savings account has no embedded gain. Treating them as equal in the settlement gives the stock recipient $12,000 less in real value.

Dependent Exemptions and Child Tax Credits

Only one parent can claim each child as a dependent. The default rule is that the custodial parent (the parent with whom the child lives for more than half the year) claims the child. But the custodial parent can release the exemption to the non-custodial parent by signing IRS Form 8332.

This release is often used as a negotiating tool in settlement agreements. If the non-custodial parent is in a higher tax bracket, the child tax credit is worth more to them. The custodial parent can agree to release the exemption in exchange for other concessions — higher child support, a larger property share, or other benefits.

Include the specifics in the PSA: which parent claims which child, whether the release is permanent or alternates years, and whether the release is contingent on current child support obligations being met.

The Alabama Divorce Financial Split Guide includes a pre-tax versus post-tax asset comparison worksheet that calculates the real after-tax value of each asset in your settlement — so you know what you are actually getting before you agree.
