Frequently Asked Questions
See exactly how much property tax credit you're owed at closing. Our free property tax proration calculator helps you protect every dollar of your savings.
A: Property tax proration is the process of splitting the annual property tax bill between the buyer and seller based on how many days each party owns the home during the tax year. The seller pays for the days they owned the property; the buyer covers the rest. This adjustment typically appears as a credit on the closing disclosure (CD).
A: The formula is straightforward:
Daily Tax Rate = Annual Tax ÷ Total Days in Tax Period
Seller's Share = Daily Tax Rate × Number of Days Seller Owned the Property
Enter your annual tax amount, tax period start/end dates, and closing date into the calculator — it handles the rest instantly.
A: It depends entirely on the closing date. If a home closes on June 29 in a standard January–December tax year, the seller is responsible for 179 days (January 1 through June 28, assuming the buyer pays for closing day). Every day earlier or later directly changes the seller's dollar amount owed.
A: - Paid in Arrears (most common in the U.S.): Taxes are paid after the period they cover. The seller credits the buyer at closing because the seller hasn't yet paid taxes for the days they occupied the home.
- Paid in Advance: Taxes are paid before the period. The buyer reimburses the seller for the prepaid days the buyer will occupy the home.
Your state's payment method determines which direction the credit flows on your settlement statement.
A: This is a negotiable convention, not a legal rule. The two most common approaches are:
- Buyer pays closing day (industry default in most markets)
- Seller pays closing day (sometimes negotiated in buyer's market conditions)
Our calculator lets you toggle between both options so your proration reflects the actual agreed terms.
A: The closing date is the single biggest variable in the calculation. Moving the closing date by just one week can shift hundreds of dollars between seller and buyer. A later closing date means the seller owes more days; an earlier date means the buyer absorbs more of the annual bill. Run multiple closing date scenarios in the calculator before finalizing your timeline.
A: Yes. The calculator works for any state or county — you input the actual tax period dates and annual tax amount, so local calendars and fiscal year variations are already accounted for. Note that actual escrow figures may vary slightly based on local title underwriting rules or individual purchase agreements. Always confirm final numbers with your escrow officer.
A: Absolutely. For buyers pursuing financial independence, an accurate proration calculation means you're not leaving money on the table at closing. A $6,000 annual tax bill on a mid-year close represents roughly $3,000 in seller credits — real money that belongs in your investment account, not lost in a miscalculated settlement.
