Massachusetts homeowners who are 65 or older and meet an income limit can put off paying the whole property tax bill until the house is sold or the owner dies. The program is Clause 41A of the state’s property tax law, and it is a deferral, not a discount. The application is due April 1, or three months after the town mails the tax bills, whichever date comes later. Every dollar put off comes due later with interest added.

A deferral is a loan against the house

Nothing is forgiven under Clause 41A. The town records a statement at the Registry of Deeds, and that statement becomes a lien on the home to secure the deferred taxes and the interest, according to the state Division of Local Services. The owner keeps living in the house, and the balance is settled only when it is sold or the taxpayer dies.

Owners do not have to defer everything. The Department of Revenue says an owner can defer the full tax or only part of it, for as long as the owner continues to qualify. A household that can cover half the bill can defer the other half and hold down the interest.

The state’s Department of Revenue says an owner may defer payment of all or part of the taxes owed each year. The cost is the interest. It accrues at 8 percent a year unless the city or town votes a lower rate, and the rate jumps to 16 percent after the repayment date. On a $6,000 tax bill, 8 percent works out to $480 a year. Owners deciding whether to defer or pay need that rate first, and the local assessors can say what their town charges.

Who qualifies, and where the income limit moves

Applicants must be 65 as of July 1, according to the Division of Local Services guidance on the program. The statewide income limit is $20,000 in gross receipts for the previous calendar year, and a spouse’s receipts count toward it, the Department of Revenue says. Cities and towns can raise the limit by vote, up to the state circuit-breaker credit amount, which is adjusted each year.

That local option changes the answer a lot. Milton’s assessors list a limit of $93,000 in gross annual income for the preceding year. A retiree who is turned away under the $20,000 rule in one town can fit under the cap in another, so the town where the house sits decides.

Milton’s page repeats the same core terms. An individual must be 65 or older as of July 1 of the tax year, interest charges accrue, and the deferred amount must be repaid to the town when the property is sold or the taxpayer dies.

Only the local board of assessors can decide whether an applicant qualifies, the state fact sheet says. The first-year agreement is State Tax Form 97-1, and the Division of Local Services says all co-owners and any mortgage holders must sign it.

The April 1 date is the later of two

The Department of Revenue puts the deadline this way: the application is due on April 1, or three months after the actual tax bills are mailed, whichever is later. The fact sheet adds that assessors cannot waive or act on a late application. Milton’s page is stricter in plain terms, saying applications must be filed with the assessors every year, no later than April 1.

The three-month rule matters in towns that mail bills late. A bill mailed in mid-January, for example, would carry a filing date in mid-April, because that is three months later and it falls after April 1.

The filing repeats annually. Owners have to apply again each year and keep meeting the age and income tests, because the deferral covers one tax year at a time, the state says. A deferral approved this year is not a standing arrangement.

Boston, the state’s largest city, posts its own personal exemptions page for homeowners there. Forms and local rules come from the city or town where the house sits, not from one state office.

The 50 percent ceiling

The deferral has a cap. The Department of Revenue says the total of deferred taxes and accrued interest cannot be more than 50 percent of the owner’s share of the property’s full and fair cash value. The Division of Local Services describes the same test. For a home valued at $400,000, that ceiling is $200,000 in taxes and interest combined.

Because interest counts toward the 50 percent, a long run of deferred years uses up room faster than the tax bills alone would suggest. The balance also falls due when the owner dies, which means an estate or heirs inherit the repayment along with the house.

The open question for each owner is whether 8 percent interest, rising to 16 percent after repayment comes due, costs more than the cash that stays in the household each year. The town’s assessors set the rate that decides it.

Tax bill bigger than the monthly income?

A deferral that looks painless in the first year can leave a heavy balance and a lien on the house years later. The April 1 date, the town’s income limit and the interest rate are all set locally, and a missed filing cannot be fixed after the fact.

The Senior Property Tax & Home-Cost Relief Kit lays out the 5 kinds of property-tax relief side by side, so a deferral can be weighed against freezes and credits that carry no lien. It runs 64 pages, with Part 7, The Yearly Routine, and an application log and renewal calendar for tracking each filing date.
