When a divorcing couple sells the family home, property tax touches the sale in three places: the closing statement, the buyer’s first bills and the seller’s own exemption. This page follows the tax through a sale so nothing is a surprise. It is general information; your attorney and tax professional advise on your case.
Divorce and Property Tax
Selling the Home in a Divorce: Property Tax and Closing
What happens to the property tax when a divorcing couple sells the family home: the buyer’s new value, prorations at closing, the exemption and the bills that follow.
A sale is a change in ownership
When the home is sold to a third party, the county reassesses it at the price the buyer pays. The seller’s tax bill, which may reflect a value set decades ago, does not carry over. That is why the buyer’s bill can be much higher than yours was, and why buyers ask about it during negotiations. If it helps, you can show them how it works with the property tax estimator.
Worked example

How a supplemental bill is worked out
The example buys at $930,785 (the typical home value in the San Diego metro area) a home the seller’s bill valued at $370,000, a made-up figure. Tax is figured at 1.15%. The assessor’s own math governs.
| Step | Result |
|---|---|
| New value at purchase | $930,785 |
| Old assessed value | $370,000 |
| Supplemental assessed value (difference) | $560,785 |
| Annual tax on the difference at 1.15% | $6,449 |
| Closing | Months taxed | Approximate supplemental tax | Why |
|---|---|---|---|
| Closing in October | 8 months | $4,299 | From the first of the following month (November) to the end of the fiscal year on June 30 |
| Closing in March | 15 months | $8,061 | The rest of the current fiscal year (April to June, 3 months) plus the whole next fiscal year (12 months) |
The supplemental bill does not replace the regular bill; it is added to it. A lender’s escrow account usually pays the regular installments, and a supplemental bill often comes to the owner by mail, sometimes a few months after closing. It is worth asking your lender and title company who will receive and pay yours.
What happens at closing
Escrow prorates the property tax between the seller and buyer according to the closing date, so each side pays for the days they owned the home. The bill for the current installment period may be paid at closing, or credited to the buyer, depending on what has been paid. The escrow officer prepares a statement showing each line, and it goes to both spouses along with the rest of the closing figures.
Rudy’s article on divorce home-sale timelines lays out how long each step usually takes.
Your homeowners’ exemption and the next bill
- The exemption: if you had the $7,000 homeowners’ exemption, tell the assessor when you no longer qualify, and file a new claim for the next home you own and live in (Form BOE-266).
- Your mailing address: give the county your new address so notices reach you.
- After the sale: if a supplemental or corrected bill arrives for a period when you owned the home, escrow’s statement and your attorney can help you sort out who is responsible.
The data
Where San Diego values sit
Typical values across the metro area now and at earlier points, for context on pricing.
Today against the last five years
Zillow typical value for the San Diego metro area. A temporary reduction under Prop 8 depends on a home’s own market value on January 1, not on an area average.
| When | Typical value | Compared with now |
|---|---|---|
| Latest (Aug 2026) | $930,785 | — |
| A year ago | $926,328 | −0.5% vs now |
| Two years ago | $950,559 | +2.1% vs now |
| Highest in the last five years (Jul 2024) | $951,005 | +2.2% vs now |
The typical value today is about 2.1% below its highest point of the last five years ($951,005 in Jul 2024). An owner who bought near that point and whose own home’s market value on January 1 was below its assessed value could ask the assessor to review it.
Common questions
Do we pay the property tax until the sale closes?
Whoever owns the home is responsible for it. Escrow divides the current bill between seller and buyer at closing.
Can the buyer’s tax bill affect the sale price?
Buyers consider the monthly cost, including tax. The price and terms are negotiated, and your agent can help with the numbers.
Does selling change my own tax situation?
There can be income tax questions about the sale itself. Those belong with your tax professional.
What if we disagree about when to sell?
That is for the spouses, attorneys or the court. Rudy’s options article lays out the choices neutrally.
