How property tax works in North Carolina
- Rates: counties and cities each set a rate per $100 of assessed value. Inside a city you pay both; outside, the county rate only.
- Reappraisal: counties revalue all property at least every eight years. Between reappraisals assessed values can drift below market value, which is why the state also publishes an effective rate adjusted by each county's sales assessment ratio.
- When it's due: bills are mailed in summer and due September 1, but can be paid without interest until January 5. After that, interest starts at 2% and adds 0.75% each month.
- Exemptions: there is no general homestead exemption. Owners 65+ or totally and permanently disabled with income under the state limit can exclude the greater of $25,000 or 50% of their home's value; apply by June 1.
How to lower your property tax in Onslow County
- Check your assessed value after each county reappraisal. You can ask for an informal review, then appeal to the county board of equalization and review — usually in the spring of a reappraisal year.
- Apply for the elderly or disabled exclusion (65+ or totally and permanently disabled, under the state income limit) by June 1: it excludes the greater of $25,000 or half of the home's value.
- Pay by January 5 to avoid interest — bills are due September 1, but interest only starts on January 6.
