Homeowners must register with New York State to keep their Basic STAR exemptions, with the registration requirements to prevent millions in fraud, according to Gov. Andrew M. Cuomo’s office.

Basic STAR saves homeowners $700 every year, on average, but is only available on the primary residence of owners with incomes below $500,000, Cuomo said.

The registration deadline is Dec. 31.

Homeowners must register even if they initially applied for Basic STAR with their local assessors.

Seniors receiving Enhanced STAR are not impacted.

To register visit www.tax.ny.gov or call 518-457-2036.

The Tax Department has extended call center hours for STAR Registration from 8:30 a.m. to 8 p.m. Monday through Friday and 9 a.m. to 1 p.m. Saturdays.

A study by the Department of Taxation and Finance last year found that thousands of individuals with multiple properties were receiving more than one STAR exemption. The registration requirement is designed to ensure that homeowners only receive one STAR exemption, said Cuomo.

“In just six weeks, more than one million homeowners have registered for their STAR exemptions, a huge boost in our efforts to protect New Yorkers from fraud in the program while ensuring eligible homeowners continue to receive the tax relief they deserve,” Cuomo said.

“I encourage all New Yorkers who are eligible for STAR to follow the lead of these homeowners by registering for this tax exemption today.”
