If you are comparing Henrietta, Pittsford, Brighton and Penfield, you have probably already had the moment. Two houses, same square footage, same year built, same asking price. One listing shows a tax figure that is roughly double the other. Nobody explains why.

This post explains why. You will learn what a New York tax bill is actually made of, why assessment is not the same thing as price, which five variables cause two comparable houses to cost hundreds a month apart, and exactly where to pull verified numbers for any specific address. I am not going to quote you a tax rate table. Rates change by tax year, they change by district, and a stale number in a blog post is worse than no number at all. What I will give you is the method I use with buyers, and the places I send them to check my work.

What a New York property tax bill is actually made of

Here is the first thing most buyers from out of state get wrong. There is no single Monroe County property tax. There are several separate taxing bodies billing the same parcel, and they do not coordinate with each other.

For most buyers, the school portion is the largest single piece. That matters, because school district lines do not follow town lines. This is the part that surprises people most.

Assessment is not your purchase price

Your bill is your assessed value multiplied by the combined rates, minus any exemptions. So the assessment drives everything.

Each town assesses independently. Some towns assess at or near full market value. Some carry assessments that lag the market, and the state applies an equalization rate to keep county and school levies fair across town lines. The practical consequence: you cannot compare a raw tax rate in one town to a raw tax rate in another and learn anything useful. A lower rate applied to a higher assessment can produce a larger bill than a higher rate applied to a lower one.

Two more things buyers miss:

• The seller's exemptions are not yours. A tax figure on a listing may reflect a STAR exemption or another exemption tied to the current owner. Your bill after closing can be different. Basic and Enhanced STAR have their own eligibility rules and application steps through New York State, and Enhanced STAR carries income and age requirements. Confirm what applies to you rather than assuming the number on the listing carries over.
• Assessments get revisited. A town reassessment, or a sale that establishes a new market value for the parcel, can change the assessed figure. Ask the assessor when the town last did a townwide update.

The five variables that move two identical houses hundreds apart

When I walk two similar houses in different towns and the tax lines are far apart, it is almost always one or more of these.

1. School district. Different districts, different voted budgets, different levies. A house in West Henrietta and a house in Pittsford can be a ten minute drive apart and sit in districts with entirely separate budgets. Districts also cross municipal boundaries, so two houses on the same Henrietta street can fall into different districts. I check the district on the parcel record, not on the listing description.
2. Assessed value versus what you are paying. A house assessed well below its current market price will show a low current tax figure. That figure is describing the past, not your future.
3. Village status. A parcel inside the Village of Pittsford or the Village of Honeoye Falls carries a village tax that a comparable parcel in the surrounding town does not. Village services come with a village line on the bill.
4. Special districts. Fire, sewer, drainage and lighting districts vary parcel to parcel. A newer subdivision with its own sewer district can carry line items that an older parcel on the next road does not.
5. Lot and improvements. Assessors value land and structures. Acreage, a detached garage, a finished basement counted as living area, an in ground pool: all of it can sit in the assessed value even when two houses look identical from the road.

Pittsford vs Henrietta property taxes: how to compare them honestly

The only comparison worth making is address to address, not town to town. Here is the sequence I run for buyers looking at property taxes in Henrietta, NY against a Pittsford or Brighton alternative.

• Pull the parcel on the Monroe County real property portal. Get the assessed value, the school district, and the current tax figures by component.
• Read the components separately. County and town, school, village if applicable, special districts. Write them down as separate lines, because that is how you will see where the difference actually comes from.
• Call or email the town assessor's office. Ask when the town last reassessed, whether an update is planned, and what exemptions are currently reducing this parcel's bill.
• Ask what happens to the assessment after a sale at your offer price.
• Do the same thing for the competing address. Then compare the totals, not the rates.

That process takes maybe twenty minutes per house. It replaces every guess in this decision with a number you can defend.

Turn the difference into a monthly figure before you fall for a house

Taxes usually go into escrow with your mortgage payment, so a tax gap shows up in your monthly cost the same way a rate change does. The arithmetic is simple: annual tax difference divided by twelve. A gap of $2,400 a year is $200 a month. A gap of $3,600 a year is $300 a month.

For scale on the other side of the payment, Freddie Mac's Primary Mortgage Market Survey put the 30 year fixed rate at 6.65% on August 20, 2026, against 6.58% a year earlier. Rates moved seven basis points over twelve months. A tax difference between two towns can move your monthly payment more than that rate change does, and unlike a rate, you cannot refinance out of it.

One more piece of context on what you are buying into. The National Association of Realtors reported a Rochester metro median sales price of $252,800 in the first quarter of 2026, up 7.2% year over year, which the Rochester Business Journal noted was the 10th largest first quarter increase among the nation's 235 largest markets. Prices in the south and southeast towns run their own course, and I do not trust aggregator town level medians for this. One national site published a Pittsford median sale decline of 38.6% for December 2025 built on three closed sales. Three. That is noise printed as a headline.

The questions to ask before you sign

• What is the current assessed value, and what is the full market value the town is using?
• Which school district bills this exact parcel?
• Is the parcel inside a village?
• Which special districts appear on the bill, and what does each cost?
• Which exemptions are on the bill now, and which of them will end at closing?
• When are the tax bills due, and will my lender escrow both of them?
• Has the owner ever grieved the assessment, and what happened?

New York property taxes explained properly are not complicated. They are just assembled from parts that nobody hands you in one place. Once you have the parts for two specific addresses, the choice between towns usually gets clearer, not harder.

If you want help pulling parcel records and running the real monthly numbers on the houses you are weighing in Henrietta, Pittsford, Brighton, Penfield or the Honeoye Falls and Mendon area, book a time with me and bring your shortlist. We will go address by address.
