New York Divorce Financial Planning: Equitable Distribution, 2026 Maintenance, IRMAA at $300K

The single most important fact about a New York divorce is that New York is an equitable-distribution state, not a community-property state. Under NY Domestic Relations Law §236(B)(5)(c), the court is instructed to divide marital property "equitably" — which means based on the 14 statutory factors at §236(B)(5)(d), not on a presumption of 50/50. In practice, New York courts often arrive at near-equal splits for long marriages with comparable contributions, but the analysis is fact-specific. A stay-at-home spouse who supported a Wall Street career may receive more than 50% of the marital estate. A spouse who entered the marriage with significantly greater premarital wealth and kept assets separate may end up retaining more than 50%.

For a New York couple with $300K combined AGI, $2M of investable assets, a marital home in White Plains or on the Upper East Side, and 12 to 20 years of marriage, the planning problem is layered: federal QDRO rules govern the retirement asset split, federal §121 exclusion governs the home, New York DRL §236(B) governs the equitable allocation of everything else, and New York Tax Law §612 governs the state income-tax treatment of any payments between the spouses. Get any one of these wrong and the after-tax outcome shifts by six figures.

Equitable distribution under NY DRL §236(B): the 14 factors that drive the split

New York's equitable-distribution statute is one of the most factor-heavy in the country. The court must consider (paraphrased from §236(B)(5)(d)):

• The income and property of each party at the time of marriage and at the commencement of the divorce
• The duration of the marriage and the age and health of both parties
• The need of a custodial parent to occupy or own the marital residence
• The loss of inheritance and pension rights upon dissolution of the marriage
• The loss of health insurance benefits
• Any award of maintenance
• Any equitable claim to, interest in, or direct or indirect contribution to the acquisition of marital property by the party not having title
• The liquid or non-liquid character of all marital property
• The probable future financial circumstances of each party
• The impossibility or difficulty of evaluating any component asset or interest in a business, corporation, or profession
• The tax consequences to each party
• The wasteful dissipation of assets by either spouse
• Any transfer or encumbrance made in contemplation of a matrimonial action without fair consideration
• Any other factor which the court shall expressly find to be just and proper

The "tax consequences" factor at §236(B)(5)(d)(11) is the lever New York financial planners use to justify allocating different asset types to different spouses. A $500K Roth IRA and a $500K Traditional IRA are not equivalent: after federal tax at a 22% bracket, the Traditional IRA is worth $390K to the spouse who eventually withdraws. Allocating the Roth to one spouse and the Traditional to the other without an after-tax adjustment violates the spirit of equitable distribution.

Worked example: $2M marital estate in Westchester, 16-year marriage, $300K AGI

Consider an Albany-area or White Plains couple, 16 years married, with the following marital balance sheet:

• Primary residence in Scarsdale: $1.4M (mortgage $400K, equity $1M)
• His 401(k) at JPMorgan: $850K (entirely marital, contributions began during marriage)
• Her Roth IRA: $180K (entirely marital)
• Joint Schwab brokerage: $320K ($180K basis, $140K unrealized gain)
• Joint cash: $80K
• His pension at JPMorgan: $14K/month at age 65 (joint life value approximately $2.1M)
• Total liquid + retirement assets (excl. pension): $2.43M; equity in home: $1M; combined marital estate: ~$3.43M including pension value

His income: $240K. Her income: $60K (returned to part-time work after children).

A near-equal split under §236(B)(5)(c) might look like:

• She takes the house ($1M equity) plus an additional $200K from the Schwab brokerage
• He keeps the 401(k) ($850K) and his pension ($2.1M present value)
• She keeps her Roth IRA ($180K)
• Joint cash split 50/50 ($40K each)
• He pays her $56,400/year in maintenance for approximately 4–6 years under the guideline formula

The after-tax math is where most New York attorneys stop and a CDFA® picks up. His $850K 401(k) is pre-tax — when he withdraws at retirement, federal + NY state + NYC tax of approximately 32% reduces the after-tax value to about $578K. Her Roth IRA at $180K is fully tax-free. Her $1M home equity is largely tax-free if she sells later and qualifies for the §121 exclusion ($250K for single filers post-divorce). His pension, at full payout, will be ordinary income taxed at his then-current bracket.

On a strict gross-asset basis, the split is roughly 50/50. On an after-tax basis, she comes out slightly ahead because her assets are taxed less harshly. The equitable adjustment usually flows through the maintenance award and the duration — and the §236(B)(5)(d)(11) tax-consequences factor explicitly permits the court to deviate from a strict 50/50 to reflect this.

The 2024/2026 New York maintenance guideline formula

New York's maintenance guideline at §236(B)(6)(c) is formulaic — but only up to the income cap of $228,000 of payor income (2026 figure under §236(B)(6)(b)(4), adjusted biennially by the Office of Court Administration). For payor income above the cap, the court has discretion under the §236(B)(6)(e)(1) factors.

The formula has two cases:

• With child support order in effect: maintenance = (20% × payor income) − (25% × payee income), capped at 40% of combined income minus payee's income.
• Without child support: maintenance = (30% × payor income) − (20% × payee income), same cap.

For the example above (no children at home, husband $240K, wife $60K):

• Payor income capped at $228K
• Maintenance = (30% × $228K) − (20% × $60K) = $68,400 − $12,000 = $56,400/year

Duration is also formulaic under §236(B)(6)(e):

• Marriage 0–15 years: 15–30% of length
• Marriage 15–20 years: 30–40% of length
• Marriage 20+ years: 35–50% of length

A 16-year marriage yields 4.8 to 6.4 years of maintenance under the guideline. The court retains discretion within the range.

Critical TCJA interaction: under the Tax Cuts and Jobs Act, alimony executed after 2018-12-31 is no longer deductible by the payor or taxable to the payee for federal income tax purposes. New York did NOT decouple — under NY Tax Law §612(c)(1), New York follows the federal treatment. So $56,400/year of maintenance is paid with after-tax dollars by the payor. At a 32% federal + 6.85% NY State + 3.876% NYC marginal rate, the pretax-equivalent cost to the payor is about $90,000. This is the single largest economic shift in modern New York divorce, and many guideline calculations still implicitly assume the old tax regime — leaving payors materially worse off than the formula suggests.

The New York estate tax cliff: a divorce-as-estate-planning consideration

New York imposes a separate estate tax distinct from the federal estate tax. The 2026 exemption is $7.16M, but the structure is a cliff, not a phase-out: estates exceeding 105% of the exemption ($7.518M) lose the exemption entirely and are taxed on the full value from the first dollar. This is codified at NY Tax Law §952(b).

For divorcing couples whose combined marital estate is between $7M and $14M, the divorce itself becomes an estate-tax planning event. Two individual $4M estates owe $0 in New York estate tax. A single $8M estate owes approximately $696,000 in New York estate tax (the cliff erases the exemption and applies the 3.06% to 16% rate schedule on the full $8M). The divorce mechanically separates the estates and eliminates the cliff exposure — but only if the planning is done correctly and each spouse maintains separate residence and estate-plan documents post-divorce.

New York's estate tax rate schedule under Tax Law §952(c):

• $0 to $500K: 3.06%
• $500K to $1M: 5%
• $1M to $1.5M: 5.6%
• $1.5M to $2.1M: 6.4%
• $2.1M to $2.6M: 7.2%
• Top bracket above $10.1M: 16%

For couples whose combined estate is approaching or exceeding $7M, the divorce attorney and the estate planner should be in the same room.

IRMAA coordination at $300K AGI post-divorce

Medicare Part B and Part D premiums increase with income via the Income-Related Monthly Adjustment Amount (IRMAA). The surcharge tiers are based on MAGI from two years prior — so 2026 premiums use 2024 MAGI. The tiers under CMS regulations:

• Single ≤ $103K / MFJ ≤ $206K: $185/mo Part B, no Part D surcharge
• Single $103K–$129K / MFJ $206K–$258K: $259/mo Part B, +$13.70 Part D
• Single $129K–$161K / MFJ $258K–$322K: $370/mo Part B, +$35.30 Part D
• Single $161K–$193K / MFJ $322K–$386K: $480.90/mo Part B, +$57.00 Part D
• Single $193K–$500K / MFJ $386K–$750K: $591.90/mo Part B, +$78.60 Part D
• Single $500K+ / MFJ $750K+: $628.90/mo Part B, +$85.80 Part D

The divorce changes the filing status, which changes the IRMAA tier. Pre-divorce MFJ at $300K MAGI falls in the $258K–$322K tier ($370/mo Part B + $35.30 Part D each = about $9,720/year per couple over the base). Post-divorce, two singles each at $150K MAGI fall in the $129K–$161K tier (same $370/mo Part B + $35.30 Part D each = same $9,720/year — no change). But if the income concentrates: a single filer at $240K is in the $193K–$500K tier ($591.90 + $78.60 = $670.50/mo), while the other ex-spouse at $60K is below all surcharge tiers. The combined household post-divorce IRMAA bill drops to about $8,046/year — a modest savings, but it changes which spouse bears the cost.

For divorcing couples approaching Medicare age (both spouses 63 to 65), the IRMAA tier the lookback year falls into has a real cash impact. A spouse who takes a lump-sum payment of $200K in 2024 — for example, a 401(k) rollover characterized as alimony, or a capital-gain harvest to fund the property settlement — can spike that spouse's 2024 MAGI and trigger IRMAA tier increases two years later. Planning around the IRMAA lookback is one of the most underused levers in pre-65 divorce settlements.

QDRO mechanics for the JPMorgan 401(k) under federal and New York law

The federal QDRO statute is at ERISA §206(d)(3) and IRC §414(p). The basic mechanics — pre-approval by the plan administrator, designation of the alternate payee, division as a percentage or dollar amount — are entirely federal. But the divorce decree that drives the QDRO must come from a New York court under DRL §236(B). The sequence:

• The New York Supreme Court (the trial-level court in matrimonial actions) issues the divorce decree allocating the 401(k) — for example, "50% of the marital portion as of date X."
• The QDRO is drafted, typically using the plan's pre-approved model language (Fidelity, JPMorgan, Vanguard, and Schwab all have model QDROs).
• The QDRO is submitted to the plan administrator for pre-approval. The administrator either approves or returns it with required changes.
• The New York judge signs the approved QDRO.
• The plan administrator implements the division. The alternate payee can leave the funds in the plan, roll to an IRA, or take a distribution (the 10% early-withdrawal penalty under IRC §72(t)(2)(C) is waived for QDRO distributions to an alternate payee).

The malpractice trap: the QDRO must be drafted, approved by the plan, and signed by the judge before the divorce decree is final. If the decree is final but the QDRO is never executed, the non-employee spouse has a paper claim against an asset they cannot actually access. We have seen New York cases where 5+ years passed before the alternate payee realized there was no QDRO on file with the plan, and by then the employee spouse had remarried and updated the beneficiary. Recovery becomes litigation, not paperwork.

For the example above — his $850K JPMorgan 401(k), her 50% award — the QDRO should specify: (a) the dollar amount or percentage as of the valuation date, (b) the treatment of investment gains/losses between the valuation date and the actual division date, (c) whether the alternate payee takes a separate accounting within the plan or a rollover to an IRA, and (d) the survivor benefit treatment if the participant predeceases the alternate payee.

The marital home: §121 exclusion and the New York mansion tax

Federal IRC §121 allows a $250K exclusion of capital gain on the sale of a primary residence ($500K for MFJ), provided the seller has owned and used the home as a primary residence for 2 of the last 5 years. After divorce, each ex-spouse is a single filer with a $250K exclusion. For the example above (Scarsdale home, $1.4M value, $400K mortgage, $1M equity, original purchase price $700K), a sale immediately after the divorce by the spouse who keeps the home (assuming she meets the use/ownership test) would realize $700K of gain. Her single-filer $250K exclusion leaves $450K of taxable gain. At 15% LTCG + 3.8% NIIT (because her MAGI post-divorce exceeds $200K with maintenance plus earned income) + 6.85% NY state + 3.876% NYC = approximately $135,000 in tax on the sale.

The §121 timing trick: if the spouses sell the home BEFORE the divorce is final and while still filing jointly, they can use the $500K MFJ exclusion. $700K gain − $500K exclusion = $200K taxable at the same rates above = about $60,000 in tax. The decision of when to sell — before or after the decree — swings the tax bill by $75,000 in this example.

New York mansion tax: New York State imposes an additional 1% transfer tax on residential property sales of $1M or more, codified at Tax Law §1402-a. New York City layers on a graduated mansion tax from 0.25% (sales of $2M+) to 4.15% (sales of $25M+) under NYC Administrative Code §11-2102. For the Scarsdale home at $1.4M, the New York State 1% mansion tax adds $14,000 to the buyer's closing costs (though by contract this can shift between buyer and seller). For a Manhattan or Brooklyn marital home over $2M, the mansion tax can exceed $40,000. This belongs on the settlement spreadsheet.

Pension valuation under NY DRL §236(B)(5)(d)(5)

New York courts have specifically held that defined-benefit pensions are marital property to the extent they accrued during the marriage. The standard valuation methods are:

• Present-value method: an actuary calculates the present value of the future pension stream using current mortality tables and a discount rate. The non-employee spouse receives an offsetting share of other marital assets equal to half the marital portion of the present value.
• Deferred-distribution method (the "Majauskas formula" from the 1984 NY Court of Appeals decision in Majauskas v. Majauskas): the non-employee spouse receives a percentage of each pension payment when it is eventually paid. The formula is: (months married during pension accrual) ÷ (total months of pension accrual) × 50% × each monthly payment.

For the JPMorgan pension above ($14K/month at 65, $2.1M present value, 16 years of marriage during a 22-year work history at JPMorgan): the Majauskas share would be (16 × 12) ÷ (22 × 12) × 50% = 36.4% of each future pension payment. At $14K/month, that is approximately $5,090/month to the ex-wife starting at his age 65, for as long as the pension is paid.

The decision between present-value and deferred-distribution methods is one of the largest variables in New York divorce. Present-value gets the non-employee spouse cash now (via offsetting other assets) but exposes her to the actuarial assumptions used. Deferred-distribution preserves her interest in the actual pension stream but ties her to the employee spouse's longevity and the plan's solvency.

Tax-loss harvesting and asset selection in the New York divorce

For the joint Schwab brokerage with $140K of unrealized gain: which spouse receives which positions matters. New York follows federal tax treatment for capital gains under Tax Law §612 — no preferential state rate, but no surcharge either. A position with a built-in loss has different post-divorce value than one with a built-in gain. The transferring spouse's basis carries over to the receiving spouse under IRC §1041 (the divorce-related transfer rule that suspends recognition of gain or loss on transfers between spouses incident to divorce). So if she takes a position with $50K of unrealized gain, she inherits the basis — and the tax bill if she sells.

The planning move: in a 50/50 brokerage split, allocate the higher-basis positions (small unrealized gain) to the spouse in the higher post-divorce tax bracket, and the lower-basis positions (large unrealized gain) to the spouse in the lower bracket. For the example above, if she will be in the 22% federal bracket post-divorce and he will be in the 32% bracket, she should take the heavy-gain positions — she will pay 15% LTCG vs. his 15% LTCG, but the NIIT bite changes (her MAGI may be below $200K single, eliminating the 3.8% surcharge; his MAGI well above $200K triggers the full 3.8%). The net difference: roughly $5,300 of tax savings on every $140K of gain by allocating to the lower-MAGI spouse.

Key takeaways

• New York is an equitable-distribution state under NY DRL §236(B)(5)(c) — not 50/50, but the 14 factors at §236(B)(5)(d) often produce near-equal splits for long marriages with comparable contributions.
• The 2026 New York maintenance guideline formula caps at $228K of payor income; above that, judicial discretion applies. For a $300K-AGI couple with no children, the guideline payment is around $56,400/year — paid with after-tax dollars post-TCJA, costing the payor ~$90K pretax-equivalent in a 32%+ NYC bracket.
• The New York estate tax has a $7.16M exemption and a brutal cliff at $7.518M — estates above the cliff lose the exemption entirely. For couples with combined estates between $7M and $14M, divorce is an estate-tax planning event.
• IRMAA coordination matters at $300K AGI. The lookback uses MAGI from two years prior, so divorce-related cash events (401(k) rollovers, capital-gain harvests) can spike a single year's MAGI and trigger Medicare surcharges two years later.
• QDRO mechanics are federal (ERISA §206(d)(3), IRC §414(p)) but require the New York court's approval. The QDRO must be drafted, plan-approved, and judge-signed BEFORE the decree is final — this is the single largest preventable error in New York divorce.
• The §121 exclusion timing on the marital home swings the tax bill by tens of thousands. Sell while still MFJ ($500K exclusion) vs. after divorce as single ($250K exclusion) is a major planning lever for Westchester, Manhattan, and Long Island homes over $1M.
• New York has specific pension-division precedent under Majauskas v. Majauskas — the deferred-distribution formula is the default, but present-value offsets are common. The choice between methods is one of the largest variables in NY divorce.
