Property taxes complicate every real estate transaction — and most buyers and sellers don’t fully understand how they work at closing. Who owes what? How are taxes prorated? What happens to your assessment after you buy? Will your taxes jump? This guide answers all of it.
How Property Taxes Are Handled at Closing
Property taxes are almost always prorated at closing — responsibility is divided between buyer and seller based on how many days each owned the property during the tax year. If paid in arrears (most common), the seller owes taxes from January 1 through closing — a credit given to the buyer at settlement. Your closing disclosure will show exactly how taxes were prorated.
As a Buyer: Will Your Taxes Increase?
This is one of the most important questions any buyer should ask — and one agents frequently get wrong. The answer depends entirely on your state’s assessment rules.
- States that reassess at sale: Many states reassess at or near the sale price when a property transfers. A seller who paid $3,000/year might be replaced by a buyer paying $7,000/year for the same property (Michigan is a notable example).
- Florida: The Save Our Homes cap resets when a property sells. A buyer pays taxes based on the full current assessed value with no cap benefit until they’ve owned for a year.
- California: Proposition 13 sets your base assessed value at your purchase price. Your taxes are predictable and low relative to future appreciation.
Research Before You Buy
Before making an offer, verify the actual property tax history and understand what your bill will likely be after purchase. Do not rely on the listing agent’s representation of “current taxes” — that number may reflect a long-term owner’s capped assessment that will increase significantly when the property sells.
Exemptions: What You Lose and Need to Re-Apply For
When you buy a property, any exemptions the previous owner had — homestead, senior, veteran — do not transfer to you. You need to apply for your own exemptions after closing. Make applying for your homestead exemption part of your post-closing checklist.
Challenging Your First Assessment as a New Buyer
If your first assessment notice seems too high relative to what you paid, you have the right to appeal. In many states, the purchase price itself is strong evidence of market value. See our complete guide on how to appeal your property tax assessment.
