1. Which Agency Handles Your Tax Dispute?
Start with the issuing agency and tax listed on the notice. A city address does not establish jurisdiction, and some taxes bearing the city’s name follow state procedures.
City Business Taxes and Property Assessments
The NYC Department of Finance (DOF) administers several business taxes, including the Business Corporation Tax and Unincorporated Business Tax. The NYC Tax Appeals Tribunal hears eligible disputes involving city-administered taxes, excluding real property tax.
Challenges to a property’s assessed value generally follow the NYC Tax Commission process. Real Property Transfer Tax disputes concern a separate tax and may fall within the Tribunal’s jurisdiction.
State and Federal Tax Notices
New York State administers city personal income tax and sales and use taxes. Eligible protests proceed through the state’s Bureau of Conciliation and Mediation Services (BCMS) or Division of Tax Appeals.
IRS notices follow federal procedures, including U.S. Tax Court review where authorized. Neither the federal court nor the state administrative system replaces the city Tribunal for a DOF dispute.
2. What Does the Notice Require?
A request for records differs from a formal assessment or refund denial. The document’s title, tax period, and protest instructions help establish what response is available and when it is due.
Audit Requests and Formal Determinations
During an audit, taxpayers can explain discrepancies and provide supporting records. A proposed adjustment does not necessarily carry the same appeal rights as a statutory notice.
Once a formal notice arrives, further discussions with the examiner should not be treated as extending the protest deadline. Sending documents to an auditor is also different from filing a formal challenge.
Disputing Liability or Arranging Payment
A liability dispute challenges whether tax applies or how the agency calculated it. Accepting the balance but needing time to pay raises a separate collection issue.
Identify disputed tax, penalties, and interest individually. A payment arrangement does not itself decide the merits, and penalty relief does not necessarily reduce the underlying tax.
3. Challenging a City Tax Determination
Eligible DOF disputes may proceed through conciliation or a Tribunal hearing. The tax and notice determine the available deadline; filing and service rules determine how to submit the challenge.
Conciliation and Direct Tribunal Review
A DOF conciliation conference allows taxpayers to present arguments and documents in an informal settlement setting. Taxpayers may instead petition the Tribunal directly, so conciliation is not a mandatory first step.
An unresolved conference does not automatically become a Tribunal case. A taxpayer seeking further review must submit a timely petition under the applicable rules.
Notice-Specific Deadlines
DOF generally allows 90 days from mailing a Notice of Determination to request conciliation. Certain overseas circumstances qualify for a longer period.
Refund denials follow different rules. DOF provides a two-year conciliation request period for specified corporation and unincorporated business tax refund denials, while other refund denials generally carry 90 days. Check the Notice of Disallowance before choosing a refund challenge.
Filing, Service, and Further Review
Follow the petition instructions for filing with the Tribunal and serving the Commissioner of Finance. Under 20 RCNY §1-17, petitions filed by mail require certified or registered mail; retain the postal receipt and submission copy.
After an administrative law judge issues a determination, either party generally has 30 days to file an exception for Appeals Division review. A taxpayer may seek review of a final Commissioners’ decision through a CPLR Article 78 proceeding in the Appellate Division, First Department, subject to the applicable judicial-review requirements.
4. Records That Explain the Disputed Amount
Organize evidence around each adjustment rather than submitting an unexplained collection of documents. Show the agency’s calculation, your position, and the records supporting the difference.
Reconcile Returns with Transactions
Relevant records may include filed returns, general ledgers, bank statements, invoices, contracts, and income-allocation schedules. Explain why those documents support a deduction, different taxable amount, or other disputed position.
If a return and the books disagree, address the discrepancy directly. Identify missing records and reliable alternative evidence rather than leaving the agency to infer an explanation.
Keep Proof of Notices and Submissions
Preserve notices, envelopes, correspondence, mailing receipts, and delivery confirmations. These records can establish the notice’s mailing history and whether a response met filing and service requirements.
Careful evidence preservation also keeps earlier explanations available for comparison. Before signing a settlement or consent, check which periods and issues it covers.
5. Frequently Asked Questions
Parallel proceedings and representation choices can affect how a taxpayer responds. These questions help identify obligations beyond the immediate disputed amount.
Not automatically. A federal adjustment may affect another tax calculation or trigger a reporting obligation, but it does not complete a separate city proceeding.
Check whether another agency requires an amended filing or response. Agreement with the IRS should not be assumed to settle a DOF assessment.
Ask which deadline applies, what evidence supports the challenge, and whether representation covers conciliation, Tribunal proceedings, or judicial review. Clarify whether payment and collection issues require separate work.
Bring the complete notice and prior correspondence. Those documents help an attorney assess the available procedure before evaluating the disputed tax.
