- Once per year, around the second week in December.
When is my payment due?
- Your taxes are due and payable in full on or before January 10th. If you are unable to pay in full, then, to avoid penalty, the 1st half must be paid on or before January 10th and the 2nd half, on or before May 31st.

When I look at my Tax Bill, it shows the former owner. Why is that? Should I be worried?
- When you purchase a property, depending on the time of year, it can take up to 6 months for it to change ownership on our system.
What if I didn’t receive my tax bill in the mail, do I have to pay my property taxes or any late fees?
- Yes. If you are the owner of a property, you are responsible for your taxes even if you do not receive your bill.
How do I obtain a copy of a Tax Bill?
- If you are the property owner and you have lost or misplaced your tax bill, please visit our Payment Portal site, Tax.IslipNY.gov. Create an account and you can download/print an un-official copy of your tax bill. Otherwise, you can visit us in person for an official copy. There is no charge to the property owner for a duplicate copy.
- If you are NOT the property owner you can request an official copy in person or by mail. The cost is $5.00 p/parcel.
I am a friend, attorney, banker, broker etc., and am working on behalf of the owner, do I have to pay the $5.00 duplicate bill fee?
- Yes. Only the owner of the property is exempt from the $5.00 duplicate bill fee. If you are working on behalf of the owner, you are a 3rd party and are subject to that fee.
If I am selling my house and the closing date is in January (end of), should I pay the first half of the taxes or just the amount owed for December and January?
- As long as you own your property, you are responsible for the property taxes on that property including any penalties that may occur during the collection season (Dec.–May). Every seller has different wants/needs. We recommend you consult with your attorney as to the right decision that fits your circumstances.
The payment coupon asks for my telephone number, why do you need it?
- Sometimes there may be an issue with your payment. In lieu of mailing the paperwork back to you, leaving a contact telephone number gives us the ability to potentially solve a problem over the phone. We do not share your telephone number.
How do I change my mailing address?
