Texas Real Estate Closing Proration Calculator

BLUF (Bottom Line Up Front): Property taxes and rental income are prorated at closing so each party is financially responsible only for their specific days of ownership. Under Texas customs, the seller owns the property through the day of closing.

Core Principles

What does this calculate?

Calculators provide immediate verification, but licensing exams require you to reconstruct this arithmetic by hand on paper. Understanding the core financial boundaries, variables, and statutory margins of this formula is critical to securing your Texas licensing credentials.

The Official Formula
Daily Rate = Annual Bill ÷ Calendar Days (360 or 365)
Seller Days = Total Days Owned from Jan 1 through Closing
Seller Share = Daily Rate × Seller Days
Adjustment = Taxes are in arrears, meaning Seller Debited and Buyer Credited.
The Student Trap

Under Texas custom, the seller owns the day of closing (meaning the closing day counts as a seller day). Many national-style exams mistakenly attribute closing day to the buyer. Additionally, check the exam question carefully: it will state whether to use a 360-day statutory year (30 days/month) or a 365-day calendar year.

Texas Case Study

Worked Texas Exam Example

Active Case Study Walkthrough
A property in Austin closes on April 18. The annual county taxes are $6,000, paid in arrears. Using a statutory 360-day year: 1. Month Days: Jan (30) + Feb (30) + Mar (30) = 90 days. April days = 18. Total seller days = 108. 2. Daily Tax Rate = $6,000 ÷ 360 = $16.67 per day. 3. Seller Tax Share = 108 days × $16.67 = $1,800. 4. Adjustment: $1,800 is Debited to the Seller, and Credited to the Buyer.
