What Is a Property Tax Deferral Versus an Exemption?

FairAppeal Editorial Team · August 21, 2026 · 2 min read

A property tax deferral postpones tax that is still owed later, often for seniors. It is not an exemption that subtracts value, and it is not an appeal.

A property tax deferral, which varies by state, postpones tax that is still owed later, often for seniors, instead of erasing the charge or rewriting the assessed value. The bill is delayed. The debt remains. An exemption subtracts from taxable value. A property tax appeal challenges the printed number.

What is a property tax deferral versus an exemption?

IAAO's Standard on Property Tax Policy says deferrals delay, but do not excuse, taxes, which accrue as a lien until the property is sold or the estate is settled. An exemption, in the IAAO glossary, excludes part or all of a category of property from taxation. One parks the bill. The other shrinks the base millage multiplies.

Example: 10 mills on $200,000 is a $2,000 yearly tax. A deferral can park that $2,000, plus later years, against the house until a sale. That running total is an example, not a state's interest table.

Look up if you are overpaying.

Is a property tax deferral the same as an appeal?

No. A deferral leaves the printed value in place and postpones collection. A property tax appeal asks that printed value to come down. The property tax glossary keeps postpone, subtract, and challenge in separate drawers.
