The seller's property tax exemption is not your tax bill

If the county record shows a senior or disabled property tax exemption, the tax figure on the listing belongs to the seller, not to you. The exemption freezes the seller's assessed value and ends at closing; your bill resets to full value. Read it as a budget item and as a clue about who is selling.

1. What the exemption does

Washington RCW 84.36.381 (checked 2026-08-26). Income thresholds are set per county as a share of median household income (RCW 84.36.383); most states run a version of this program.

To qualify in Washington, the owner must be 61 or older (or retired on disability, or a qualifying veteran), live in the house as a principal residence, and stay under the county income threshold.

2. The frozen value is the part buyers miss

Illustrative. Under RCW 84.36.381 the value is frozen at the assessment year the owner first qualified, so a long hold can mean a wide gap.

The exemption does not only trim the rate; it locks the taxable value at the year the owner first qualified. A seller who qualified fifteen years ago is still being taxed on a fifteen-year-old number. You will be taxed on this year's.

3. How it looks on the county record

Labels vary by county. The tell is a taxable value that sits below the assessed value plus an exemption code.

How

Open the parcel on the county assessor site and go to the tax or assessment tab. Compare taxable value with assessed value, then compare the bill with two similar houses on the same block.

Red flag

Listing pages copy last year's bill. If that bill was exempt, the number is not yours and any monthly budget built on it is wrong.

4. What your bill becomes

Seller's bill (exempt) frozen value × reduced levies Your bill (after closing) full value × full rate Reference: non-exempt Tacoma house (sample report), $588,900 assessed, $6,410 tax in 2026 (~1.1%).

Rebuild the number yourself: current assessed value times the local levy rate, then check the county's tax calculator if it has one. In Washington the exemption is personal to the claimant, so the year after closing the county bills the house at full value and full levies. Put that figure in the holding-cost line of your flip model and in the monthly payment if you plan to rent.

5. What it says about the seller

Long-term occupant deferred maintenance likely Fixed or low income little cash for repairs Downsizing or estate clean title, patient timeline Deferred (not exempted) taxes: the lien is paid from the seller's proceeds at closing (RCW 84.38.130).

A pattern, not a rule. Verify the story against the deed date, the mailing address, and the permit history.

An exemption usually means a long-held, owner-occupied house with a limited repair budget. That is often the raw material of a fair flip: dated inside, honest outside, no lender pressure.

Before you write the offer

  • Pull the parcel and note assessed value, taxable value, and any exemption code.
  • Recompute the bill at full value and put it in your holding-cost line.
  • Ask the title company whether a tax deferral lien exists and who pays it.
  • Check the seller disclosure for the same long-hold items: roof, sewer, electrical.

Why we check this on every deal. A tax bill copied from the listing is one of the quiet ways a flip model goes wrong. Our methodology reads the county tax page directly and flags exemptions and deferrals before any number reaches the profit line.

FAQ

Does a senior property tax exemption transfer to the buyer?

No. In Washington the exemption under RCW 84.36.381 is personal to the claimant: they must be 61 or older or retired due to disability, own and occupy the home as their principal residence, and stay under the county income threshold. When the home changes hands the new owner does not inherit it, and the county returns the property to full assessed value and full levies.

How much will my property taxes go up after buying an exempt house?

It depends on how long the seller's value was frozen and which income tier they were in. The frozen value dates to the year they first qualified, so a decades-long exemption can mean a large gap. Model your bill as current assessed value multiplied by the local levy rate, then confirm with the county assessor before you write the offer.

Where do I see the exemption on county records?

Open the county assessor's parcel page and look at the tax or assessment section. Typical signs are an exemption code or a line such as Senior/Disabled Exemption, a taxable value lower than the assessed value, and a tax bill that is well below similar houses on the same street.

What is the difference between an exemption and a deferral?

An exemption reduces the bill. A deferral under chapter 84.38 RCW postpones it: the state pays the tax and records a lien, and the deferred amount becomes due when the property is sold. A deferral is a seller-side debt cleared at closing; an exemption is a discount that disappears with the seller.
