Tax Implications of Divorce in New York: What You Need to Know

The Tax Cuts and Jobs Act of 2017 changed the tax treatment of spousal maintenance for agreements or judgments executed after December 31, 2018:

• The paying spouse can no longer deduct maintenance payments from their federal taxable income.
• The receiving spouse no longer includes maintenance in their federal taxable income.

This is a significant change. Before 2019, maintenance was deductible for the payor and taxable to the recipient. The new rules can affect negotiations — particularly the effective cost of maintenance for high-earning payors who previously received a deduction. New York State, however, did not follow the federal change — see the next section.

This is the single most misunderstood point in New York divorce tax planning, and it is worth stating plainly: New York decoupled from the federal repeal. For New York State income tax purposes, maintenance paid under an instrument executed after December 31, 2018 is still deductible by the payor and still taxable to the recipient — the pre-2019 treatment New York has kept.

Because the federal return no longer accounts for it, New York implements this through two modifications on Form IT-225, New York State Modifications:

• S-136 — a subtraction from federal adjusted gross income for applicable alimony or separate maintenance payments paid.
• A-119 — an addition to federal adjusted gross income for applicable alimony or separate maintenance payments received.

Two practical consequences follow. First, the state deduction has real settlement value: a payor in a high New York bracket still gets a state-level benefit that simply does not exist federally, and a recipient should understand that the money is not tax-free at the state level even though it is federally. Second, the paperwork is reciprocal — the payor must attach a statement giving the recipient’s Social Security number or ITIN, and the recipient must furnish that number to the payor. Building that obligation into the settlement agreement avoids an awkward exchange the following April.

The same treatment can be extended to a pre-2019 agreement that is later modified, but only if the modification expressly says the Tax Law § 612(w) addition and subtraction modifications apply. If you are modifying an older agreement, that language should be a deliberate drafting decision rather than an afterthought. See our spousal maintenance calculator and our guide to New York’s maintenance guidelines for how the underlying number is calculated in the first place.

Transfers of property between spouses as part of a divorce are generally not taxable events at the time of transfer under IRC § 1041. You do not pay capital gains tax when you transfer the house, investment accounts, or other assets to your spouse as part of the divorce.

However, the spouse who receives the property takes it at the original cost basis. If they later sell it, they will owe capital gains taxes based on that original basis — which may be significantly lower than the current value. This means an asset worth $200,000 on paper may have very different after-tax value depending on its basis. Always consider embedded tax liability when dividing assets.

When the marital home is sold as part of the divorce, each spouse may be able to exclude up to $250,000 in capital gains from federal income tax ($500,000 if filing jointly), provided they meet the ownership and use tests.

If one spouse keeps the home and later sells it, they may only be able to exclude $250,000 — not the joint $500,000. The timing of when you sell matters significantly.

Your tax filing status for a given year is determined by your marital status on December 31 of that year. If your divorce is finalized on December 30, you cannot file jointly for that year. This can have a significant impact on your tax liability, particularly regarding tax bracket and deduction eligibility.

If you are separated but not yet divorced, you may still be able to file jointly — or may prefer to file as "married filing separately." The choice depends on your financial situation; a tax professional can run the numbers.

The parent who has the child for more than half the year (the custodial parent) generally claims the child tax credit by default. However, this can be allocated differently by agreement or by signing IRS Form 8332, which transfers the right to claim the child to the non-custodial parent.

This is a negotiating point in divorce settlements, and the number went up. The child tax credit is now worth up to $2,200 per qualifying child (raised from $2,000 by the 2025 federal tax law and indexed for inflation going forward), with up to $1,700 of it refundable through the Additional Child Tax Credit for parents whose tax liability is low. The full credit phases out above $200,000 of income for a single filer and $400,000 for joint filers. That is real money — and in a multi-child family, alternating or splitting the children between the parents is a routine and worthwhile settlement term.

Dividing retirement accounts via QDRO is not a taxable event at the time of transfer. However, if the receiving spouse takes a distribution rather than rolling the funds into their own retirement account, income taxes and potential penalties apply. Plan ahead to avoid unnecessary tax costs when dividing retirement assets.

Many newly separated parents default to "single" once their divorce is finalized — but the Head of Household status is often more favorable and is available even before the divorce is final, provided you meet the IRS tests. To qualify generally requires: (a) being unmarried or considered unmarried on the last day of the year (which can include being separated and living apart from your spouse for the last six months of the year), (b) paying more than half the cost of keeping up a home for the year, and (c) having a qualifying child or other dependent live with you for more than half the year.

Head of Household offers a larger standard deduction than single filers and more favorable tax brackets. For tax year 2026 the standard deduction is $24,150 for a head of household versus $16,100 for a single filer — roughly $8,000 of additional income shielded from federal tax, before the more favorable bracket structure is even counted. For a parent newly running a household on a single income, the difference can be meaningful. Two practical implications worth surfacing in any divorce involving children: (1) the parties should think early about which parent will meet the "more than half the year" residency test before the school calendar locks in, and (2) the right to claim Head of Household is separate from the right to claim a child as a dependent (which can be released via IRS Form 8332), so the two should be addressed independently in the settlement.

Two benefit accounts that frequently get overlooked in a mid-year separation are Health Savings Accounts (HSAs) and Dependent Care Flexible Spending Accounts (FSAs). HSAs are owned individually but contribution limits depend on the type of high-deductible health-plan coverage in place during each month of the year — moving from family to self-only coverage mid-year changes the maximum, and a "last-month rule" testing period can create unexpected income inclusion if the coverage isn't maintained. Dependent Care FSAs, in contrast, are use-it-or-lose-it employer-tied accounts that don't transfer between spouses and are tied to a specific custody arrangement; what was a useful benefit while filing jointly may not be reimbursable after separation if the day-care expenses fall on the spouse who isn't the FSA holder.

Neither account is a settlement deal-breaker, but both belong on the divorce financial worksheet alongside retirement accounts and the marital home — particularly when changes in health insurance, day-care arrangements, or dependent claims are happening at the same time.

The tax implications of your divorce settlement can rival the face value of the assets themselves. A divorce settlement that looks equal on paper may be very unequal after taxes. Involving a CPA or financial planner alongside your divorce attorney — especially in complex or high-asset divorces — is money well spent.

One structural point worth understanding as of 2026: the 2017 Tax Cuts and Jobs Act provisions that reshaped divorce taxation are no longer scheduled to expire. The 2025 federal tax law made the individual provisions permanent, raised the child tax credit, and began indexing it for inflation. In practical terms that means the post-2018 maintenance treatment is not a temporary regime you can plan around outlasting — it is the baseline. Dollar figures still move each year with inflation, so confirm the current-year numbers with a CPA before you sign, but the underlying architecture is now stable.
