How to pay OnGov property taxes without using the wrong link

Outside City of Syracuse
Use the Onondaga County tax payment route for town properties outside Syracuse. RPTS says those properties can view/print bills and receipts or pay online.
City of Syracuse
Use the separate City of Syracuse tax payment route. Do not use the outside-city county/town route for Syracuse properties.
Delinquent county/town tax
After the local collection window, delinquent non-Syracuse county/town taxes go to Onondaga County Finance/RPTS collection.

Confirm city or town before payment
This is the biggest wrong-link mistake.

| Date / Window | What It Means | Action |
|---|---|---|
| March 1 | Common taxable status date and exemption application deadline in most NY communities; Onondaga RPTS says March 1 is the exemption deadline for county properties outside Syracuse City limits. | Check STAR, senior, disability, veteran and other exemption status before deadline. |
| May 1 | Tentative assessment roll is made public in most communities. | Check assessment, exemptions and property data as soon as the roll opens. |

| July 1 | Final assessment roll in most communities. | Tax bills are based on the final assessment roll. |
| September | School tax bills mailed in the beginning of September in most NY communities. | Confirm district, STAR benefit and school tax due date. |

How Onondaga County property tax is generally calculated
Use this for understanding the bill. The exact amount depends on your municipality, school district, special districts, exemptions and final roll value.
Simple estimate path
Estimated tax = taxable assessed value × applicable tax rates, plus special district charges or unpaid prior-year amounts if any.
Assessment is not always market value
New York uses a uniform percentage of market value. A municipality may assess at 100% of market value or another uniform percentage.
Exemptions change taxable value
STAR may apply only to school tax, while other exemptions may affect different taxing jurisdictions differently.
Special districts matter
Fire, sewer, water and other district charges can make two nearby properties have different bills.
Delinquent tax can include prior years
Onondaga County says unpaid tax may represent delinquent county/town taxes and could include unpaid school/village taxes from prior years.
What to do if your OnGov tax bill or assessment looks wrong
Payment offices collect bills. They usually do not fix value, exemptions, STAR, property classification or ownership-condition issues.
| Problem | Call / Use First | Prepare Before Contacting |
|---|---|---|
| Assessed value too high | Town/city assessor before Grievance Day. | Comparable sales, photos, appraisal, repair estimates, SBL and tentative roll value. |
| STAR missing or wrong | Assessor / NYS Tax STAR route. | Owner details, income/age status if relevant, property address and tax bill. |
| Owner name or mailing address wrong | Assessor/RPTS address update route. | Deed/closing documents, mailing address and SBL. |
| Payment not posted | Town receiver if current; county RPTS/Finance if delinquent. | Receipt, confirmation, check copy, amount, date and tax year. |
| Inside Syracuse but using county route | City of Syracuse finance/tax payment route. | Property address, SBL, city bill and payment confirmation if already paid. |
| Auction or foreclosure concern | Onondaga County RPTS / Finance. | All tax years owed, notices, owner information and property SBL. |
Check early, not after bills
Assessment challenges usually happen after the tentative roll and before Grievance Day, not after the tax bill arrives months later.
Only total assessment is grieved
New York’s assessment roll guide explains land and improvement values appear separately, but the total assessment is what is reviewed.
March 1 is critical
Most exemption applications are tied to taxable status date. Onondaga RPTS says March 1 is the outside-Syracuse county property exemption deadline.
