Keep the House or Take the 401(k)? How California, Texas, New York, and Pennsylvania Rules Change a $400K vs. $400K Divorce Split by $66K

Here is a scenario I see constantly. A couple has been married 14 years. One spouse earns $140,000 and the other earns $60,000. The marital estate is a house worth $600,000 with a $200,000 mortgage, plus a $400,000 401(k) in the higher earner's name. The offer on the table: one spouse keeps the house ($400K of equity), the other keeps the 401(k) ($400K). Sounds equal?

After taxes and selling costs, on the assumptions below, there is a $66,400 gap between those two "$400K" assets. Whether that gap is a problem, a bargaining chip, or already baked into what a court would do depends on your state, your income gap, and how long you were married.

Below I'll run the numbers, show how four states change the starting point, and point out where the other variables (insurance, debt terms, alimony) can move the answer further. Your numbers will differ. That is the point of the exercise.

This is educational math, not legal advice. Consult your attorney for legal questions.

Step 1: Convert both assets to what you could actually spend

A pre-tax retirement account and home equity are different animals. Every dollar withdrawn from a traditional 401(k) is taxed as ordinary income. Home equity is taxed only on the gain, and the first $250,000 of gain is excludable for a single filer under IRC §121 if you meet the ownership and use tests.

Worked example assumptions (all illustrative):

House value: $600,000. Mortgage: $200,000. Equity: $400,000.
Original purchase price plus improvements (tax basis): $250,000.
Selling costs: 6% of $600,000 = $36,000.
401(k): $400,000, pre-tax, taxed at a blended 28% federal-plus-state rate on withdrawal.
Long-term capital gains rate: 15% federal. State tax on the gain is ignored, which favors the house.

The house, if sold:

Line	Amount
Sale price	$600,000
Less selling costs	($36,000)
Amount realized	$564,000
Less basis	($250,000)
Gain	$314,000
Less §121 exclusion (single)	($250,000)
Taxable gain	$64,000
Federal tax at 15%	$9,600
Equity after mortgage: $400,000 − $36,000 − $9,600	$354,400

The 401(k), if fully cashed out: $400,000 × (1 − 0.28) = $288,000.

Total after-tax estate: $642,400. A true 50/50 split is $321,200 each.

Instead, the "equal" offer hands one side $354,400 and the other $288,000. That is a $66,400 spread. Put another way, the house side is holding about 55.2% of the after-tax estate.

If you want to see how the retirement side gets taxed and split in the first place, our post on IRA transfer in divorce vs. QDRO covers the mechanics and penalty traps. Our house vs. 401(k) analysis at 7% mortgage rates covers the financing side.

This is the kind of analysis Sevaryn runs for you, so you don't have to build the spreadsheet yourself.

Step 2: Why "who gets the higher number" isn't the whole story

The house holder looks ahead by $66,400 on paper. But several things pull the other way:

The tax on the house is latent. It only appears if you sell. If you stay 20 years and prices rise, the §121 exclusion may not cover the larger gain. If you die holding it, the rules change again. The 401(k)'s tax bill is more predictable.
Liquidity. You can't buy groceries with drywall. The 401(k) holder can draw from the account (with taxes, and potential penalties depending on age and how the money is moved). The house holder needs a sale or a loan to access equity.
Carrying costs. Property taxes, insurance, and maintenance continue. On a $60,000 income, the spouse keeping the house may face a bigger monthly burden than the 401(k) spouse.
Growth. The 401(k) can be invested in diversified assets. Home equity depends on one property in one market.

Nothing here says one side "wins." It says the label "$400K each" tells you almost nothing until you model it.

Step 3: Check the insurance before you accept the house

CNBC Personal Finance reported that many homeowners have a homeowners insurance coverage gap and don't know it, putting them at financial risk. In a divorce this matters twice.

First, if you take the house, you take the risk that the policy wouldn't fully cover a rebuild or a major loss. A $600,000 market value is not the same thing as a rebuild cost, and policy limits, deductibles, and exclusions vary. Ask for the declarations page and have the dwelling coverage limit checked before you sign.

Second, a policy with both names on it will need to be rewritten when title changes. Make sure the new policy is in place at the transfer date, not weeks after.

I'd treat an unexamined policy as a hidden liability on the house side of the ledger. It won't appear on any asset schedule, but it can cost real money.

Step 4: How your state changes the starting split

The same $642,400 after-tax estate doesn't start from the same place everywhere. Here's how the four states in my example frame the division. These are general descriptions and your attorney will tell you how they apply to your case.

State	System	Starting point	Residency to file (general)
California	Community property	Presumptive equal division of community property (Family Code §2550)	6 months in state, 3 months in county (Family Code §2320)
Texas	Community property	Court divides the community estate in a "just and right" manner, so unequal splits are possible (Family Code §7.001)	6 months in state, 90 days in county (Family Code §6.301)
New York	Equitable distribution	Fair, not necessarily equal, based on statutory factors (DRL §236(B)(5))	Generally 1 to 2 years depending on the circumstances (DRL §230)
Pennsylvania	Equitable distribution	Fair division after weighing factors including income, marriage length, and each spouse's future needs (23 Pa.C.S. §3502)	6 months (23 Pa.C.S. §3104)

Residency matters more than most people realize. If you moved recently, the state where you can file, and sometimes how property acquired elsewhere is treated, may change your outcome. Our post on moving states before filing for divorce walks through a $138,750 swing.

Step 5: The same offer under three split assumptions

Here is what the lower-earning spouse (the one who would keep the house) receives after tax under three illustrative outcomes. I'm not predicting what any court would do. I'm showing the sensitivity.

Scenario	House-side spouse	401(k)-side spouse	Difference from 50/50
A. Offer as written (house vs. 401(k))	$354,400 (55.2%)	$288,000 (44.8%)	$33,200
B. True 50/50 after-tax	$321,200	$321,200	$0
C. 55/45 favoring lower earner	$353,320	$289,080	$32,120
D. 60/40 favoring lower earner	$385,440	$256,960	$64,240

Look at Scenario A against Scenario C. The "equal" offer is nearly identical to a 55/45 after-tax split. If your state's starting rule is equal division and there's no strong argument for deviating, the offer above gives the house side about $33,200 more than a 50/50 after-tax split. If your state weighs income disparity and a 14-year marriage, the offer might already be close to where a negotiation would land. And if the disparity argument is stronger in your case, Scenario D shows the offer may be short for the house side.

To equalize Scenario A to 50/50, the house-side spouse would owe about $33,200, which could be a cash payment or a cash-out refinance. At a 7% rate, borrowing $33,200 costs roughly $2,324 per year in interest. If the numbers can't support the loan, you may be looking at a sale.

You can model this for your specific situation at Sevaryn. Change the state, the basis, the tax rate, and the split percentage, and see how the gap moves.

Step 6: Layer in income disparity and alimony

In my example, one spouse earns $80,000 more than the other. That gap can feed into alimony, and alimony is where people accept the first number most often.

Suppose the settlement includes $1,800 per month for 7 years. Total payments: $151,200. But money later is worth less than money now. Discounting at 4% compounded monthly gives a present value of about $131,800. A lump-sum buyout below that figure costs the recipient value. A lump sum above it costs the payer.

Two notes on tax. For divorce instruments executed after 2018, alimony is not deductible by the payer and not taxable to the recipient (the TCJA repealed the old IRC §71 treatment). And modification risk differs by state and by how the agreement is written. Our post on alimony for 7 years vs. a $185K lump sum walks through the discounting step by step.

The interaction matters. Suppose the lower earner takes the house and a smaller alimony stream. Their carrying costs are higher and their cash flow is thinner. Suppose instead they take more of the 401(k) and higher alimony. Their cash flow is stronger but their growth asset is taxable on the way out. The right mix depends on income, age, and how long each spouse expects to work.

Step 7: Debt terms can move the answer, too

If one spouse takes on student loans as part of the deal, don't just look at the balance. Look at the payment structure. NerdWallet's guide to refinancing student loans notes that stretching your repayment term lowers the monthly payment but increases the interest you pay over the life of the loan.

Example: $60,000 at 6.5%.

Term	Monthly payment	Total interest
10 years	about $681	about $21,756
20 years	about $447	about $47,376

Stretching to 20 years lowers the payment by about $234 a month but adds roughly $25,600 in interest. If you're offered a "lower payment" through refinancing after the divorce, that isn't free money. It's a trade of cash flow now for cost later. It's also worth knowing that refinancing federal loans into a private loan can mean losing federal protections, so check the terms.

When you compare settlement offers, put the debt on the ledger at what it will actually cost you, not just its balance.

Step 8: Why the small details are worth the trouble

Tax Foundation estimates that Americans will spend 6.9 billion hours complying with IRS filing and reporting requirements in 2026, costing about $387 billion in lost productivity. Add $157 billion in out-of-pocket costs and the total exceeds $544 billion. That's the national picture for people with stable filing situations.

A divorce piles more onto it: a new filing status, dividing basis records, a QDRO, alimony under post-2018 rules, and possibly a home sale with §121 paperwork. Missing a basis record can cost real money. In my example, an extra $50,000 of documented improvements would reduce the taxable gain from $64,000 to $14,000 and cut the federal tax by $7,500. Documenting basis is dull work with a measurable payoff.

Our post on IRC §1041 carryover basis and filing status covers what happens to basis when property moves between spouses.

A checklist before you accept any "equal" offer

Convert everything to after-tax values. Use your actual marginal rate, not a guess.
Confirm your state's starting rule. Community property, equitable distribution, and any residency issue.
Get the tax basis on the house in writing. Include documented improvements.
Check the homeowners policy limits if you're keeping the house.
Model the cash flow, not just the balance sheet. Can you carry the house on your income after alimony and child support?
Price debt by total cost, not monthly payment.
Discount alimony to present value before comparing it with a lump sum.
Ask your attorney how the state rules apply to your facts, and whether a QDRO or transfer is needed to move the retirement money without penalties.

The bottom line

A $400K house and a $400K 401(k) are not equal. In my worked example they differ by $66,400 after taxes and selling costs, and the offer amounts to a 55/45 split. In a community property state with a presumption of equal division, that's one conversation. In an equitable distribution state weighing a 14-year marriage and an $80,000 income gap, it's a different conversation. Insurance gaps, debt terms, and alimony present value can push the answer in either direction.

The only way to know where your offer lands is to run your own numbers. Before you sign anything, model your state, your basis, your tax rate, and your income gap at Sevaryn, then take the results to your attorney.
