New York Property Tax Calculator (Assessed Value & Millage Rates)

Nationally, New York's #5 ranking and 1.45% average effective rate put it well above the national median. That is meaningfully above the national average of roughly 1.0%, based on the average effective rate across all 50 states. Compared with the rest of the Northeast, which averages roughly 1.61%, New York lands modestly below its neighbors.

New York's STAR (School Tax Relief) program trims the school-tax portion of the bill for owner-occupied homes, though it does not offset the state's generally high overall rates. Local governments, school districts, and county services in New York still depend on the resulting revenue to fund day-to-day operations, so the mechanism changes the trajectory of a bill more than the starting rate does.

Assessments are handled at the county level in New York, where local appraisers periodically revalue residential and commercial parcels and apply the applicable millage rates; homestead exemptions and formal appeals remain the main levers available to individual owners looking to manage the bill, alongside any local bond measures voters approve along the way.

New York is really several property tax systems sharing a border. New York City and Nassau County sort property into four classes with their own assessment ratios and growth caps, while the rest of the state runs town-by-town assessments at locally chosen ratios. At 1.45% the statewide effective rate ranks fifth in the country.

None of that detail is asked for here. This calculator works one level up, applying New York's average effective property tax rate of 1.45% to the value you enter. That rate is the ratio of property taxes actually paid to home value across the state, so the assessment ratios, caps, and exemptions described above are already baked into it.

Working through it in order:

1. Start from the assessing unit's value. Towns and cities assess at their own uniform percentage of market value, and the state publishes an equalization rate to compare them.
2. Apply STAR. The School Tax Relief benefit arrives as an exemption for long-standing recipients and as a check for newer ones, plus enhanced STAR for qualifying seniors.
3. Multiply by the effective rate. At 1.45%, a $400,000 home in New York comes to $5,800 a year before any exemption you enter above.
4. Divide by twelve for escrow. That same home works out to $483.33 a month set aside in a mortgage escrow account.
5. Compare it against your own bill. Because assessment ratios vary by town, a nominal New York tax rate means little without the equalization rate beside it. Your county's number is the one that governs; this figure tells you whether it is roughly where a New York home of that value ought to land.

Using this calculator's baseline inputs: a $400,000 home in New York, taxed at the state's 1.45% average effective rate (rank #5 of 50 states).

1. Start with the assessed value. The home is assessed at its full $400,000.00 market value, with no homestead exemption applied in this baseline scenario.
2. Apply the effective rate. $400,000.00 × 1.45% = $5,800.00 in annual property tax, New York's statewide average effective rate.
3. Convert to a monthly escrow. Lenders typically collect property tax in twelve equal installments alongside principal and interest: $5,800.00 ÷ 12 = $483.33 per month.
4. Project a five-year hold. At a flat rate, five years of ownership totals $5,800.00 × 5 = $29,000.00, before any reassessment, exemption change, or millage increase.

At 1.45%, New York ranks among the highest in the nation, at #5 of 50 states. That is a substantial carrying cost for homeowners.

New York's 1.45% is applied as a single statewide effective rate, so the twelve-row value sweep is a straight line and every question worth asking is about slope, direction, and what the line leaves out.

Ten thousand dollars of valuation, priced. Raising the assessed value from $400,000 to $410,000 moves the annual tax from $5,800.00 to $5,945.00. Every additional $10,000 of New York valuation costs exactly $145.00 a year, at every value the calculator accepts. Doubling the value to $800,000 doubles the tax to $11,600.00 to the cent.

The sweep, row by row. The table steps the value in increments of $66,666.67, from $66,666.67 in row one to $800,000 in row twelve, and the tax column rises by exactly $966.67 on every row without a single break. Row six carries the $5,800.00 baseline; row twelve carries $11,600.00, which is precisely double it.

Running it backwards from the bill. Divide by 0.0145. A $10,000 annual bill corresponds to $689,655.17 of assessed value, and the $400,000 baseline is the value that produces the $483.33 monthly escrow line. Because the relationship is exactly linear with no cap, no cliff and no minimum, there is no valuation at which the arithmetic bends.

Following the exemption from headline to row six. Entering a $25,000 exemption reduces the taxable assessed value to $375,000 and the annual tax to $5,437.50, a saving of $362.50 a year against the $5,800.00 the page returns with the field at zero. That reduction reaches the headline, the monthly escrow figure and the twelve-row schedule alike. With $25,000 entered, row six prices $400,000 of value at $5,437.50, the same figure as the headline, and row one falls from $966.67 to $604.17. Because every row nets the same exemption off before applying the 1.45% rate, the table can be read straight across against the result above it rather than being treated as a separate gross-value answer.

The escrow figure, and the comparison that misleads. The escrow figure is where the common error lives. The monthly line the engine reports is $483.33, being $5,800.00 divided by twelve. Lenders frequently collect a cushion of up to two months on top, so a servicer's actual monthly draw on this property can run above $483.33 without any of the tax figures on this page being wrong. Comparing a servicer's escrow line directly against $483.33 and concluding the assessment is wrong is the mistake this page most often provokes.

What the rate is standing in for. New York's 1.45% is a statewide average of county-level effective rates that range from under 1% in parts of the state to well over 2% in Westchester and Nassau. The engine holds no county table, so the $5,800.00 is a state-level benchmark and not a bill. The STAR school tax relief credit, which is the single largest reduction most New York owner-occupiers receive, is not applied either: it reduces the school portion of a bill this page does not itemise.

• Specific hyper-local county and municipal millage district variations within New York.
• Town and county special district charges. New York towns commonly create special districts for water, sewer, lighting, fire protection, or drainage under General Municipal Law and bill the resulting charge alongside the general property tax bill; these vary block by block and aren't captured in this calculator's statewide average.
• Commercial vs residential assessment classification differentials.
• Property tax appeal reductions or localized board of equalization adjustments.

• Confusing Market Fair Value with Assessed Basis: Some jurisdictions assess property at fractional ratios rather than 100% of market value.
• Failing to File Homestead Paperwork: Homestead exemptions are rarely automatic; homeowners must file timely paperwork with the county appraisal district.
• Underestimating Post-Sale Supplemental Assessments: Purchasing a newly constructed or reassessed property often triggers catch-up supplemental tax bills.
• Ignoring Property Tax Appeal Windows: Missing the annual 30-to-60 day statutory protest window forfeits the right to challenge over-assessed property values for that tax year.
