NYC property assessments begin with the Department of Finance valuing each property and establishing the assessment information used in the property-tax system. DOF issues an annual Notice of Property Value (NOPV), generally mailed in January, for the coming tax year. The NOPV is not a tax bill and does not require payment. It is the notice that explains the property information, valuation, assessment, tax class, and related figures that can affect later tax calculations.
Owners should review the NOPV even when the property tax is paid through a mortgage servicer. A valuation issue, incorrect building description, wrong tax class, missing exemption, ownership-record problem, or other inconsistency can affect later filings or tax treatment. The correct response depends on what is wrong because DOF valuation review, property-information updates, administrative corrections, and NYC Tax Commission appeals are different procedures.

A change in market value does not automatically produce the same percentage change in the final tax bill. Assessment limits, exemptions, abatements, the applicable tax rate, and other account items can affect the amount ultimately billed.
A Request for Review is the DOF procedure used when an owner believes the tentative assessed value or valuation is incorrect. DOF opens the annual RFR period after the tentative assessment roll is issued, and the filing deadline varies by tax class and tax year. The current DOF assessment-and-valuation forms page should be checked before filing because prior-year dates should not be reused.
A Request to Update is used when descriptive property information on the NOPV is incorrect or outdated. Examples can include property characteristics, classification, or other descriptive information. An RTU addresses the property record and is not the same as a valuation appeal.
DOF also provides an administrative-review procedure for certain clerical or factual errors in the assessment or tax record. It is intended for eligible ministerial or factual errors rather than a disagreement with valuation methodology or interpretation of law.
The NYC Tax Commission is separate from DOF. A Tax Commission application can be used to challenge the assessed value, tax class, or certain exemption decisions within that agency’s jurisdiction. Filing a DOF Request for Review does not replace a Tax Commission filing, and the two processes can have different deadlines, standards, and consequences.
SLK Buildings is available to coordinate NOPV review, DOF property-assessment research, Request for Review filings, property-information updates, administrative corrections, supporting records, related property-tax account issues, and multi-agency property-record coordination.

NYC Department of Finance (DOF) requirements can affect property owners, boards, managing agents, developers, business operators, and project teams when a property assessment, tax account, annual filing, tax benefit, land record, tax map, or property debt issue needs to be reviewed or coordinated. DOF values and assesses real property, bills and collects property taxes, administers many exemptions and abatements, maintains City Register records and ACRIS, and manages tax-map and tax-lot records.
Before relying on a DOF record or filing path, owners and project teams should confirm the property tax class, market and assessed values, taxable value, current tax-account status, exemptions or abatements, required annual filings, ownership and deed records, BBL information, tax-lot configuration, and any related DOB, HPD, DEP, OATH, or other agency conditions.

No. The NOPV is the annual assessment notice for the coming tax year. It explains valuation and assessment information. The property tax bill is a separate account statement that shows amounts due and other account activity.
An RFR asks DOF to review the property’s tentative assessment or valuation. An RTU is used to correct or update descriptive property information shown on the NOPV. The correct filing depends on what information is wrong.
No. The NYC Tax Commission is a separate agency. A Tax Commission application can challenge assessed value, tax class, or certain exemption decisions, while a DOF RFR is a DOF review procedure. Filing one does not automatically satisfy the other.
Yes. Assessment information is part of the property-tax calculation, but the final bill also depends on tax class, applicable assessment limits, exemptions, abatements, the tax rate, credits, and other account items.
Yes. SLK can compare DOF records with DOB, ACRIS, tax-map, ownership, and project records, identify the inconsistency, and coordinate the appropriate correction or related agency filing within the agreed scope.
