Property taxes in Sullivan County can be very confusing to new buyers. If you’re from New York City, they can seem high, and there seems to be wide variations between townships, and even between similar houses within townships.
I’ve tried to answer the most common questions I get about property taxes here. Please keep in mind that the following information is not “definitive”. It’s based on my experience with property taxes and assessments here for more than a decade. For example, while clients of mine to my knowledge have not had ‘spot reassessments’ of houses after purchase, there are scenarios where that could happen to you.
The property tax system, particularly the assessment process, in New York State is very complex, even Byzantine. Some of the most seasoned Realtors don’t even really understand how it works. While the theory and law regarding assessments is standard throughout New York state (with the exception of New York City, which has a more complex system), the reality of how it plays out in practice varies from jurisdiction to jurisdiction. So YMMV (your mileage may vary)
Please note that I don’t handle assessment grievance filings, although people ask about hiring me to do it all the time. I sit on the Board of Assessment Review for my town (Delaware), so am not able to attend grievance hearings in other towns.
