Deferral programs, available in some form in a number of states, let qualifying homeowners — usually seniors, sometimes people with disabilities or limited income — stop paying their property tax bill year to year. It sounds like an exemption. It isn't.
It's a Loan, Not a Discount
When you enroll in a deferral program, the state or county pays your property tax bill on your behalf and records that payment as a loan against your home, typically as a junior lien. Nothing is forgiven — the amount deferred each year adds up, and it's secured against your property the same way a second mortgage would be.
The Interest Adds Up
Most programs charge interest on the deferred balance, and it compounds the longer you stay enrolled. Rates vary by state — Illinois charges 3% simple interest on deferred amounts each year they're carried, while Washington's program accrues 5% simple interest until the balance is repaid. A modest annual tax bill deferred for a decade or more can turn into a meaningful lien by the time it comes due.
What Actually Triggers Repayment
The deferral doesn't run forever. Repayment typically comes due when the home is sold or transferred, when the homeowner passes away, or when the home stops being the person's primary residence. When a sale happens, the deferred balance (plus accrued interest) is paid out of the proceeds at closing, the same way a mortgage payoff works — it comes off the top before the seller sees any money. Some states let a surviving spouse continue the deferral rather than forcing immediate repayment, but usually only if that spouse is above a minimum age, often somewhere between 55 and 62 depending on the state, and continues living in the home.
Whether It's Worth It
Deferral makes the most sense for someone who's genuinely cash-poor but home-equity-rich — someone whose income can't cover a rising tax bill but who has no intention of selling anytime soon and isn't worried about leaving less behind for heirs. It makes less sense for someone who might sell in the next few years, since the deferred balance and interest come straight out of the sale proceeds, or for someone counting on passing the home on debt-free. Worth checking your state's specific program rules before assuming it's free money — it isn't, it's a loan with your house as collateral.
