Updated September 5, 2026. Quick answer: North Carolina brands its program a ‘circuit breaker,’ but it works like a deferral: it caps your bill at 4% or 5% of income depending on which income tier you fall in, and if you disqualify, only the preceding three years of deferred tax come due, not the whole accumulated balance.
A ‘circuit breaker’ that is legally a deferral, and only claws back three years
North Carolina’s Property Tax Homestead Circuit Breaker, G.S. 105-277.1B, is named like a credit program but works like a deferral: homeowners 65 or older, or totally and permanently disabled, who have owned and occupied the home for five consecutive years, have their tax bill capped at 4% of income if income is at or below $38,800 for the 2026 tax year, or 5% of income if it falls between that figure and $58,200 (150% of the base limit). The state covers the rest as a deferral, not a forgiven credit, and if the owner later disqualifies; by transferring the home (other than to a co-owner or spouse who keeps living there), dying, or ceasing to use it as a permanent residence; only the preceding three fiscal years of deferred tax become due, with interest, not the entire accumulated history. Annual reapplication is required every year.
An interest mechanism that is confirmed, but not a fixed number, and a silent lien
The statute does not state a flat interest percentage; instead G.S. 105-277.1F says interest accrues on deferred taxes as if they had originally become due on their original due dates, which functionally routes to the state’s general delinquent-tax schedule of 2% for the first month and three-fourths of one percent (3/4%) a month after that; though that link is an inference from the ‘as if originally due’ language rather than an explicit named cross-reference to that specific schedule. A lien for the deferred difference attaches under the state’s general lien-attachment statute, but that statute fixes only when the lien attaches, not how it ranks against a mortgage or deed of trust; the statute is silent on priority. It does clarify one adjacent point: a mortgage holder who elects to pay the deferred tax does not thereby gain any foreclosure right.
When it comes due, and how to apply
Beyond the disqualifying events above, the annual application must be filed with the county tax assessor by June 1 preceding the tax year, on Form AV-9, with prior-year income documentation and, for applicants under 65, a separate disability certification on Form AV-9A. The state’s own form spells out the consequence in plain language: only the last three years of deferred taxes and interest come due on a disqualifying event.
