You reviewed the settlement and ran the numbers. The split looked fair. But what you may not have realized was what those assets are worth after the IRS is done with them.
The tax implications of divorce are real, specific, and frequently misunderstood. Here’s what to know.
Your Filing Status Changes (and It Costs More Than You’d Expect)
Once your divorce is finalized, you’ll file your taxes as a single filer or as head of household if you have qualifying dependents living with you. On the surface, this sounds like a minor administrative change. In practice, it can meaningfully increase your tax bill.
The married filing jointly brackets are wider, which means more income is taxed at lower rates. When you shift to single filing, those brackets compress. Income that was taxed at 22% when you filed jointly may now fall into the 24% or even 32% bracket, depending on your earnings.
The head of household status offers somewhat better bracket thresholds than single filing and a higher standard deduction. But it only applies if you meet specific IRS criteria, including that your home was the primary residence of a qualifying child for more than half the year.
The bracket shift alone can add thousands to your annual tax bill and be a major factor in your cash flow planning. This change also affects how you think about Roth conversions, timing of capital gains, and retirement account withdrawals. Strategies that were tax-efficient for a married couple may no longer make sense for a single filer.
Alimony and Child Support Have Very Different Tax Treatments
These two forms of support are often discussed together during settlement negotiations, but they’re taxed in slightly different ways.
Child support is tax-neutral for both parties. The paying spouse receives no deduction, and the receiving spouse reports no income. It’s simply a transfer of funds.
Alimony is more complicated. For divorces finalized after Dec. 31, 2018, the paying spouse can no longer deduct alimony payments, and the receiving spouse doesn’t report them as income. If your divorce was finalized before 2019, the old rules — deductible for the payer, taxable for the recipient — still apply to your federal taxes. And while some states follow federal rules, many have their own requirements for alimony-related taxes.1
Under the current rules, higher-earning spouses have less incentive to agree to large alimony payments, since there’s no tax offset on their end. This dynamic is worth understanding if the parties are still negotiating alimony.
The Family Home Carries Tax Risk
Deciding whether to keep the family home is one of the most emotionally charged decisions in a divorce. It can also have significant tax consequences.
When a married couple sells a primary residence, they can exclude up to $500,000 of capital gains from federal income tax. Once you’re single, that exclusion drops to $250,000.2 That’s a meaningful gap, especially if the home has appreciated significantly.
If you accept the home in the settlement and plan to sell it later, you’ll be selling as a single filer with a $250,000 exclusion. You could owe capital gains on anything over that amount, potentially at the 15% or 20% federal rate, plus any applicable state taxes.
If both spouses agree to sell the home before the divorce is finalized, you may be able to take advantage of the full $500,000 married exclusion, provided you meet the ownership and use tests. This is worth exploring with a tax advisor before the settlement is structured.
Stock-Based Compensation Requires Its Own Analysis
For executives, partners, and business owners, compensation often includes equity in the form of restricted stock units (RSUs), stock options, carried interest, or deferred compensation. Each of these carries its own tax treatment, and divorcing couples who don’t address them specifically could leave value on the table.
RSUs that vest after the separation date may still be considered partially marital property depending on when they were granted and what state you’re in. The portion that is marital property will be divided, but the tax treatment on vesting and sale is not equally shared. The spouse who receives the RSUs bears the tax liability when they vest and when the underlying shares are eventually sold.
Stock options are more complex. Incentive stock options (ISOs) and non-qualified stock options (NQSOs) are taxed differently, and transferring options in a divorce can trigger immediate tax events depending on how the transfer is structured. Options that look valuable in a settlement may be worth less after factoring in the tax due on exercise.
Deferred compensation and carried interest present similar challenges. These assets are often hard to value precisely, and the tax burden on future distributions can be substantial. Getting an independent analysis of the after-tax value (not just the face value) is critical before agreeing to any division.
When Equal on Paper Isn’t Equal in Practice
Perhaps the most important thing to know is that two assets with the same stated value are rarely worth the same amount after taxes.
Let’s say Spouse A receives a $400,000 traditional IRA. Spouse B gets a $400,000 taxable brokerage account with a low cost basis. On paper, it’s a 50/50 split. In reality, Spouse A will owe income taxes on every dollar withdrawn from the IRA, reducing the real value significantly after taxes. Spouse B, meanwhile, will owe capital gains taxes when selling positions, but at the lower long-term capital gains rate and only on the gain above their cost basis.
The gap between stated value and after-tax value runs through every major type of asset in a divorce:
- Traditional retirement accounts carry full income tax liability on withdrawal.
- Roth accounts have already been taxed and are generally more valuable dollar-for-dollar.
- Taxable accounts with low cost basis carry embedded capital gains liability.
- The family home may carry a reduced capital gains exclusion for a single filer.
- Deferred compensation and equity awards may trigger ordinary income tax rates on receipt.
A settlement that doesn’t account for these differences isn’t actually equal. Once it’s finalized, it’s extraordinarily difficult to revisit.
Get the Tax Analysis Before You Sign
Most people engage an attorney to negotiate the terms of a divorce. Fewer bring in a financial advisor with tax expertise before the settlement is finalized.
A financial advisor who works with divorcing clients can model the after-tax value of different settlement scenarios and help you understand what you’re agreeing to before it becomes permanent.
If you’ve recently finalized a divorce and are concerned about the tax consequences, there’s still meaningful planning that can be done. The decisions made in the first year or two around Roth conversions, asset sales, and timing of income can significantly offset the tax drag from a settlement that didn’t fully account for these dynamics.
