NYC Department of Finance (NYC DOF) Property Tax and Property Services
The New York City Department of Finance (DOF) is the City agency that values and assesses real property, bills and collects property taxes, administers many property tax exemptions and abatements, maintains City Register land records and ACRIS, and manages the City’s digital tax maps and tax-lot records. For a property owner, board, managing agent, developer, or business operator, DOF can affect both the financial record of a property and the documents used for ownership, development, renovation, refinancing, or other transactions.
This page focuses on DOF property matters that SLK Buildings assists with. Those services include property valuation and annual assessment review, property tax bills and account issues, RPIE and Storefront Registry filings, exemptions and abatements, property-improvement tax benefits, ICAP applications, ACRIS and City Register research, tax-map and tax-lot changes, and property debt or lien-sale coordination. Other DOF programs, such as parking and certain business-tax functions, are outside the purpose of this property-focused resource.
For a topic-by-topic guide to these services, use the NYC DOF Property Tax and Property Services resource center.

When NYC DOF Assistance May Be Needed

- Your property tax account contains a balance, credit, refund issue, payment-plan question, delinquent charge, or other account condition that needs to be researched and coordinated.
- Your property is required to file an RPIE statement, Storefront Registry filing, or related supplemental registration.
- You are applying for, renewing, correcting, or documenting a property tax exemption or abatement.
- A construction, modernization, expansion, rehabilitation, green-roof, solar, MCI, or other eligible property improvement may affect a tax-benefit filing or require coordination with DOB, HPD, DHCR, or another agency.
- An industrial or commercial project may qualify for ICAP and the filing must be coordinated with the building-permit and construction schedule.
- You need deeds, recorded documents, BBL information, or other City Register records from ACRIS for a filing, transaction, ownership review, or project record.

- Unpaid property taxes or other eligible property charges create collection, payment-plan, lien-sale, or related project risks.
NYC DOF Property Services
Property Assessments and Notice of Property Value
DOF values property every year and issues the annual Notice of Property Value. The NOPV is not a tax bill. It explains DOF’s valuation and assessment information for the coming tax year and can affect later tax calculations, exemptions, and review options. SLK Buildings assists with assessment research, NOPV review, Request for Review coordination, property-information corrections, and related records. Detailed SLK guide: NYC DOF Property Assessments and NOPV.
Property Tax Bills, Payments, Credits, Refunds, and Payment Plans
Property tax bills show current and past-due charges, property-related charges, exemptions or abatements, account credits, and other billing information. Billing frequency and due dates depend on the property account. SLK Buildings assists with account research, payment and balance coordination, credits, refund requests, payment-plan documentation, and related agency follow-up. Detailed SLK guide: NYC Property Tax Bills and Payments.
RPIE Statements and Storefront Registry Filings
Qualifying income-producing properties may have annual RPIE filing obligations, and qualifying storefront premises have separate registry requirements. Filing obligations depend on tax class, assessed value, use, ownership, and other criteria. SLK Buildings assists with filing coordination, supporting records, property information, occupancy or vacancy details, and follow-up. Detailed SLK guides: NYC RPIE Filings and NYC Storefront Registry.
Property Tax Exemptions, Abatements, and Property Improvements
DOF administers or implements a range of tax benefits for qualifying properties and owners. These include homeowner and nonprofit exemptions, co-op and condo abatements, ICAP, MCI, green-roof and other improvement-related benefits, and programs coordinated with other agencies. SLK Buildings assists with eligibility research, application and renewal coordination, supporting documentation, agency follow-up, and related permit or project dependencies. Detailed SLK guides: Property Tax Exemptions and Abatements, Property Improvement Tax Abatements, and ICAP Tax Abatement.
ACRIS, City Register Records, and Tax Maps
ACRIS provides access to many recorded land records for Manhattan, Bronx, Brooklyn, and Queens, while the DOF Tax Map Office maintains tax-lot mapping and processes lot changes. SLK Buildings assists with ACRIS research, recorded-document review, BBL verification, tax-lot mergers, apportionments, condominium tax-map filings, and related DOB or OATH dependencies. Detailed SLK guides: ACRIS Property Records and Tax Lot Mergers and Apportionments.
Property Debt and Lien-Sale Matters
Unpaid property taxes and certain other property-related charges can create collection issues and may place a property at risk of lien-sale action when applicable eligibility rules are met. SLK Buildings assists with account and debt research, payment-plan coordination, agency documentation, and project dependencies involving DOF, DEP, HPD, OATH, or other agencies. Detailed SLK guide: NYC Property Debt and Lien Sales.
NYC Debt Demolisher ~ ECB Amnesty (2026-2027)
The NYC Department of Finance offers temporary relief for qualifying unpaid Environmental Control Board (ECB) judgments adjudicated through OATH. Judgments generally must have been docketed by July 15, 2026. Some matters also require accepted corrective action and timely confirmation to DOF, not just payment. The program ends January 10, 2027. Learn more in the NYC Debt Demolisher guide.
How SLK Buildings Helps
- Review DOF property records, tax class, assessments, account history, benefits, recorded documents, tax-map information, and project objectives before selecting a filing or coordination path.
- Coordinate NOPV and assessment review, property-information updates, RPIE and Storefront Registry filings, property tax account matters, exemptions, abatements, ICAP, and improvement-related benefit applications within the agreed project scope.
- Research ACRIS and City Register documents, BBL history, deeds, tax maps, tax-lot configuration, and other records needed for transactions, filings, development, or compliance work.
- Coordinate tax-lot mergers, apportionments, condominium tax-map submissions, DOF objections, supporting surveys or documents, and related DOB approval requirements.
- Organize property debt, payment-plan, refund, credit, or lien-sale records and coordinate related agency follow-up when those issues affect the property or project.
- Keep DOF work aligned with DOB permits, HPD programs, OATH or ECB judgments, DEP charges, construction schedules, and other multi-agency requirements where jurisdiction overlaps.
Important DOF Filing and Property Tax Considerations
- The NOPV is an assessment notice, not a property tax bill. Assessment review, property-information corrections, Tax Commission appeals, and later billing are related but different processes.
- Deadlines can be tax-year, tax-class, filing-type, or program specific. RPIE, Storefront Registry, exemption, abatement, ICAP, assessment-review, and other deadlines should be verified for the current filing cycle before relying on an older date.
- Property tax bills can include taxes, other property-related charges, exemptions or abatements, credits, and past-due balances. A change in one part of the property record can affect later account activity.
- ICAP is timing-sensitive. DOF currently requires the preliminary ICAP application before the first building permit is obtained, or before construction starts if no permit is required.
- Some property-improvement tax benefits are administered by DOF but depend on eligibility or approvals from another agency. For example, certain green-roof benefits involve DOB, and MCI benefits depend on qualifying DHCR-approved improvements.
- Tax-map changes may require coordination with both DOF and DOB. DOF also states that certain outstanding ECB judgment summonses must be resolved before an owner applies to divide or merge lots.
- Lien-sale eligibility can involve property taxes, water and sewer charges, and other eligible property-related charges. The type of debt and the agency that originated the charge should be identified before choosing the resolution path.

🚧 Seeking Professional Guidance on NYC Department of Finance Property Tax, Assessments, Filings, and Property Records
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.

Frequently Asked Questions
What is the difference between the NOPV and a property tax bill?
The NOPV explains DOF’s annual valuation and assessment information for the coming tax year. It is not a bill and does not require payment. A property tax bill is the later account statement showing taxes, other property-related charges, credits, exemptions or abatements, and amounts due.
Can SLK Buildings assist with property tax bills, credits, refunds, and payment plans?
Yes. These are confirmed SLK Buildings DOF service areas. SLK can research the property account, organize supporting records, coordinate refund or credit issues, assist with payment-plan documentation and agency follow-up, and identify related project dependencies within the agreed scope.
Does SLK Buildings handle RPIE and Storefront Registry filings?
Yes. SLK assists with RPIE and Storefront Registry filing coordination for qualifying properties, including property information, supporting records, occupancy or vacancy information, filing review, and agency follow-up.
Does SLK Buildings assist with tax abatements for property improvements?
Yes. SLK assists with qualifying property-improvement tax benefit matters, including ICAP and other applicable abatement programs. Some programs involve another agency for eligibility or project approval, so the filing path must be coordinated with the agency that controls that part of the process.
What can ACRIS be used for?
ACRIS allows users to search many recorded property documents and document images for Manhattan, Bronx, Brooklyn, and Queens from 1966 to the present. It can be used to review deeds, ownership records, BBL information, and other recorded documents needed for property or project research.
Can a tax-lot change require both DOF and DOB approval?
Yes. DOF states that property owners and project professionals may need approval from both DOF and DOB to divide or merge lots. The filing should be coordinated with surveys, property records, tax-map requirements, DOB approvals, and any outstanding conditions that affect acceptance.
What is a property tax lien sale?
A lien sale transfers eligible unpaid property debt to an authorized buyer. It is not a sale of the property itself, but unresolved debt after the sale can lead to additional charges and possible foreclosure proceedings. Current eligibility and sale status should be verified with DOF for the specific property.
