Many Southampton Town property owners were in shock in late April after opening their annual tax assessment notification and discovering that their home’s assessed value has changed dramatically.

Southampton Town has done a major reassessment this year, and though you won’t be able to calculate whether your property taxes will increase until the new tax rate figures are revealed with the town budgets late this fall, the tax grievance process, which allows you to challenge your assessment, is well underway.

If you would like to discuss your reassessment with the town assessor, you can call 631.283.6020 Monday through Friday from 8:30 a.m. to 4 p.m., or visit their office at town hall at 116 Hampton Road in Southampton.

The tax assessor’s office says that reasons for assessment increases range from changes in market condition (the new assessments are based on comparable sales between July 1 2017 and June 30, 2018), new construction and renovation, missing or incomplete inventory from a prior year or expired prior year court decisions.

The town has instituted an online tax grievance portal on the home page of its website at Grievances will be accepted through May 21. 

On May 21, the town’s Board of Assessment Review will be hearing grievances in person in the upper auditorium of St. Rosalie’s Church, 31 East Montauk Highway in Hampton Bays from 9 a.m. to 12:30 p.m., from 2 to 4 p.m. and from 6 to 8 p.m.
