Property Tax Proration and Assessment Risk in NYS Closings

Overview

Property tax proration - the allocation of property taxes between seller and buyer at closing - is more complex in New York than in many other states due to varying fiscal years, assessment calendars, and exemption programs across municipalities. Errors in proration calculations result in one party subsidizing the other, and sellers who lose their STAR exemption upon sale may face additional liability. Understanding the proration methodology and exemption transfer rules for your specific municipality is essential for accurate closing cost projections.

Key Strategy

Confirm the exact fiscal year and tax payment schedule for your municipality, school district, and any special districts before calculating your closing costs. Different entities have different fiscal years - NYC runs July 1 to June 30, Westchester towns typically follow January 1 to December 31, and Long Island school districts have their own cycles. If you are receiving STAR (Basic or Enhanced), understand that the exemption does not transfer to the buyer, which means the buyer's school taxes will be higher than yours. Factor this into your pricing and buyer communication.

What To Do

Work with your closing attorney to calculate prorations based on the daily tax rate: annual tax divided by 365, multiplied by the number of days you owned the property in the current tax period. Determine whether taxes have been paid in advance or are in arrears - if you prepaid beyond the closing date, the buyer credits you for the unused portion; if taxes are unpaid, the amount is deducted from your proceeds. If you are receiving STAR, understand that the buyer must apply separately. If you registered for the STAR credit (check rather than bill reduction), proration must account for this. Alert your attorney to any pending tax grievance proceedings, which can trigger post-closing adjustments.

Common Mistakes

Not confirming whether taxes are paid in advance or in arrears for your specific municipality, which leads to proration errors. Failing to account for different fiscal years across municipality, school district, and special districts, each of which requires a separate proration calculation. Not communicating STAR exemption status to the buyer, who may be surprised by higher school tax bills. Ignoring pending tax grievance results that could trigger post-closing adjustments requiring refund coordination between parties.

Frequently Asked Questions

How are property taxes split between buyer and seller at closing?

Property taxes are prorated at closing based on each party's ownership period. If you prepaid the full year, you receive a credit for the buyer's portion. If taxes are in arrears, you owe a debit for your share. In New York, tax years and payment schedules vary by municipality, so your attorney must calculate the exact proration based on local rules. Resolve the proration method in the contract to avoid disputes.

How does property tax proration work at closing?

Property taxes are prorated between seller and buyer based on the closing date. The seller pays through the closing date, and the buyer pays from closing forward. If the seller has prepaid beyond the closing date, they receive a credit. If taxes are unpaid, the amount is deducted from proceeds. Watch for pending tax grievance results, which can trigger post-closing adjustments requiring coordination between parties.

Does my STAR exemption transfer to the buyer?

No - STAR exemptions are personal to the homeowner and do not transfer with the property. The buyer must apply separately and may not qualify (Enhanced STAR requires age 65+ with income limits). This means the buyer's school tax bill will be higher than yours by the STAR amount - typically $800 - $1,500+ annually. Communicate this to buyers early so they budget accurately and are not surprised after closing.

What happens if I have a pending tax grievance when I sell?

If your tax grievance is still pending at closing, include a provision in the contract addressing how any future refund will be handled. Typically, the refund is split based on ownership periods, with the seller receiving the portion attributable to their ownership. Without this provision, the refund goes to whoever is the property owner when it is issued - which may be the buyer. Your attorney should draft specific language addressing this scenario.
