Prorated Property Tax Calculator

About this calculator

In most real estate transactions, property taxes are billed annually or semi-annually, but ownership of the home changes hands mid-period — so at closing, the tax bill has to be split fairly between buyer and seller according to how many days each of them actually owned the property during that billing cycle. This process, called proration, ensures neither party pays for taxes covering time they didn't own the home.

This calculator prorates the annual property tax based on the number of days the seller owned the home, giving the seller's and buyer's respective shares. It's a routine step performed by real estate agents, title companies, and closing attorneys when preparing a settlement statement, and buyers and sellers commonly use a calculator like this to sanity-check the proration figures on their own before signing.
