Tax bills and payment options
Union County’s Tax & Property page links users to property bill, payment, listing, search, and foreclosure information. Annual property tax bills were mailed to property owners in mid-August 2025.
Payment options include mail, drop box, phone, online payment, and in-person payment at the Tax Collector’s office on the first floor of the Union County Government Center. In-person payments are accepted Monday through Friday between 8:00 a.m. and 5:00 p.m.

Important property tax dates
Union County lists these timing rules for property taxes, listings, and reappraisal.
| Topic | Timing | User note |
|---|---|---|
| Property taxes | Due September 1 | Must be paid by January 5 to avoid interest charges. |

Appraisal and valuation records
The Appraisal Division is responsible for appraising all real property in Union County. It also defends valuation appeals before the Union County Board of Equalization and Review and the North Carolina Property Tax Commission.
Union County’s last reappraisal was effective January 1, 2025. Current assessments must reflect the market as it existed on that date. For 2026, new notices are sent only when a property’s value changes, such as for new construction, additions, demolition, renovation, rezoning, or acreage changes.
For valuation guidance, use the Union County Appraisal & Valuation page.
Appealing a property value
Property owners may appeal a valuation when they believe the assessed value is above market value as of January 1, 2025, or inconsistent with similar properties. North Carolina law places the burden on the property owner to prove the value is incorrect.
The 2026 appeal window closed on May 6, 2026, when the Board of Equalization and Review adjourned. The 2027 appeal window opens January 1 and closes when that Board adjourns its session.
Appeal information is available through the Union County notification and appeal process.
