How do you prorate property taxes at closing?
Prorations allocate costs fairly based on ownership time. Property tax proration: divide annual property tax by 365 days (or sometimes 360) to get daily tax rate, multiply by the number of days the seller owned the property, and deduct from seller's proceeds as a credit to buyer. Example: $3,650 annual tax divided by 365 equals $10 per day; seller owned for 100 days equals $1,000 owed by seller to buyer.

Real Estate Math on the Real Estate Exam
Property taxes run the entire calendar year (January through December in most states). When property changes hands mid-year, both buyer and seller have occupancy periods. The seller should pay tax only for the days they owned the property; the buyer should pay only for their ownership days. Prorational calculations ensure fairness and proper cash flow at closing. Exam questions frequently test whether you can set up and execute proration math correctly.
Understanding Real Estate Math: Key Concepts
What It Means
A proration is the allocation of ongoing costs (and sometimes income) based on ownership period. Property taxes are the most common proration on a residential real estate exam. Taxes are assessed annually, usually for the full calendar year (January 1 through December 31). When a property changes ownership mid-year, both the seller and buyer are responsible for a portion of the annual tax bill.
How It Works
The proration calculation follows these steps: First, determine the annual property tax amount. For example, annual tax might be $3,650. Second, convert annual tax to a daily rate by dividing by the number of days in a year. In the US, exams typically use 365 days per year for tax prorations (some jurisdictions use 360 for other calculations). Daily rate: $3,650 divided by 365 equals $10 per day.
Third, determine how many days the seller owned the property. If closing occurs on July 15th, and the property tax year runs January 1 through December 31, the seller owned the property from January 1 through July 14 (the day before closing, because ownership transfers at closing). Count: January (31 days) plus February (28 days) plus March (31 days) plus April (30 days) plus May (31 days) plus June (30 days) plus July 1-14 (14 days) equals 195 days.
Additional Considerations
Fourth, calculate the seller's property tax obligation: 195 days times $10 per day equals $1,950. The seller owes this amount for their occupancy. At closing, this appears as a debit to the seller (money owed) and a credit to the buyer (money the buyer receives, because the seller pays the full annual tax on the buyer's behalf, then the buyer reimburses the seller for the buyer's portion).
Alternatively, you can calculate the buyer's portion: total days minus seller's days equals buyer's days. 365 minus 195 equals 170 days. Buyer's obligation: 170 days times $10 equals $1,700. This adds up: $1,950 plus $1,700 equals $3,650 (the full annual tax).
Common variations: Some exams use a 360-day year for proration (divide by 360 instead of 365); always check the problem statement. Some properties have property tax amounts quoted as quarterly or monthly installments rather than annual amounts; you must convert to annual before prorating. Some problems include other prorations simultaneously (rent, insurance, HOA fees); treat each independently using the same daily rate methodology.
Real Estate Math Rules by State
Each state has its own rules when it comes to real estate math. Here are a few examples of how requirements differ:
California
California uses a July 1 to June 30 fiscal year for property taxes (not the calendar year). Prorations are calculated using 365-day year. The annual tax bill is paid in two installments (November and February for the fiscal year). Exam questions may reference 'fiscal year' or show tax amounts that differ from a calendar year basis; adjust your calculation accordingly.
Texas
Texas uses the calendar year (January 1 to December 31) for property tax assessments. Prorations use 365-day year. Property taxes are paid in two installments (typically October and January). Exam questions test accurate day counting and the impact on closing statements; be careful with month-end and year-end closings.
Florida
Florida uses the calendar year for property taxes (January 1 to December 31). Prorations are calculated using 365-day year. County assessors may use different bases (homestead exemptions, etc.), but the proration calculation methodology remains the same. Exam questions focus on the proration method rather than state-specific tax rates.
Always verify: (1) which fiscal/calendar year is being used for taxes, (2) whether to use 365 or 360 days, (3) which day closing occurs (ownership typically transfers at end of closing day), and (4) whether the problem asks for seller's tax owed or buyer's tax owed. A common mistake is counting the closing day in the wrong period; clarify from the problem whether the seller pays through the closing day or up to (but not including) the closing day. Double-check your day count by adding seller days plus buyer days; they should equal 365 (or 360).
