How Do Property Taxes Get Prorated When I Sell in Union County?
When you sell a home in Union County, property taxes do not just vanish at the closing table. They get prorated, split between you and the buyer based on how much of the tax year each of you owned the home, and the math shows up as a line on your settlement statement.
Here is how North Carolina's property tax year works, what proration means for your closing, and how to check that your statement got it right.
How Property Taxes Work in North Carolina
North Carolina property taxes run on the calendar year, January through December, and they are assessed against whoever owns the property. Union County bills annually, with bills going out in the second half of the year, and the amount comes from your property's assessed value multiplied by the combined tax rates of the county and, if your home sits inside one, a municipality like Waxhaw, Weddington, Indian Trail, Monroe, or Marvin.
Because the bill covers a full calendar year but arrives partway through it, a mid-year sale always leaves the question: who owes which part? Proration is the answer.
What Proration Means
Proration divides the year's tax bill between seller and buyer in proportion to their days of ownership. The seller is responsible for the portion of the year up to the closing date, and the buyer for the rest. Your closing attorney, who handles settlements in North Carolina, calculates the split and enters it on the settlement statement as a credit or debit to each side.
The mechanics depend on timing. If you close before the year's bill has been issued or paid, the seller typically credits the buyer for the seller's share of the year, and the buyer pays the full bill when it arrives. If the bill has already been paid, the credit runs the other way, with the buyer reimbursing the seller for the buyer's share. Either way, the standard purchase contract in North Carolina provides for taxes to be prorated at closing, so each side pays only for their time.
A Clear Example
Here is a purely hypothetical illustration of how the math works. Say the annual tax bill on a Union County home is 3,650 dollars, which conveniently makes it 10 dollars a day, and the sale closes at the end of June, after the seller has owned the home for 181 days of the year.
| LINE ITEM | HYPOTHETICAL AMOUNT |
|---|---|
| Annual tax bill | $3,650 (for easy math: $10 per day) |
| Seller's days of ownership | 181 days (January 1 through late June) |
| Seller's prorated share | $1,810 |
| Buyer's prorated share | $1,840 (remaining 184 days) |
| At closing | Credit moves the seller's share to whoever pays the bill |
The seller's share covers January through the closing date, the buyer's share covers the rest of the year, and the settlement statement moves the money so the party who actually pays the county is made whole. Your actual numbers will differ, but the structure of the calculation is exactly this.
Union County Notes
A few local wrinkles are worth knowing. If your home is inside town limits, your bill includes both county and municipal taxes, and both get prorated the same way. Like all North Carolina counties, Union County periodically conducts a countywide revaluation that updates assessed values, so the bill being prorated can change from one year to the next, sellers closing near a revaluation should make sure the proration uses the correct year's figures.
Also confirm any special items on your bill, such as fees or district charges, and how your contract treats them. Your closing attorney and your agent will walk through this, but it is your money, and five minutes of understanding beats a surprise at the table.

Before closing day, review the tax proration line on your settlement statement: the annual amount used, the closing date it is calculated from, and which direction the credit flows. If anything looks off, ask, adjustments are routine before signing and painful after.
