Nys Tax Audit Notices, Required Records, and Potential Costs

Review the notice for the tax category, examination period, requested documents, and auditor's contact information. Sales tax, corporation tax, and other state taxes have different reporting requirements and assessment rules.

New York Tax Law §§ 683 and 1083 generally provide a three-year assessment period for covered income and corporation taxes. Certain substantial omissions may trigger a six-year period, while unfiled or fraudulent returns and other statutory exceptions may permit assessment beyond the ordinary deadline.

Sales tax follows separate rules under Tax Law § 1147(b). Its general three-year period has exceptions for unfiled returns, willfully false or fraudulent returns, and certain fraudulent exemption documents. Written extensions may also affect the assessment deadline.

Desk audits usually involve returns, correspondence, or supporting records submitted to the Department of Taxation and Finance. The examination may concern discrepancies identified through other information sources, including federal tax data.

Field audits involve more extensive record examinations, sometimes including interviews or visits to business premises. The department generally schedules the initial appointment at least 15 days in advance and identifies the records to be made available.

Auditors may compare invoices, point-of-sale data, bank deposits, and exemption certificates with reported taxable receipts. These records can help establish whether transactions were properly classified and reported.

Exemption certificates must satisfy applicable requirements. Missing or invalid documentation may create exposure when the business cannot otherwise substantiate an exemption.

Corporation tax reviews may examine revenue reconciliation, deductions, and apportionment records. Supporting schedules should connect disputed transactions to the corresponding returns.

For sales and use tax, Tax Law § 1138(a)(1) permits the department to determine tax using available information when a return is incorrect or insufficient. An estimated assessment must use a reasonable method supported by the circumstances and information available.

A business challenging an estimate should examine whether its records justified the method and whether the sampling period, calculations, and assumptions support the assessment. Once the department establishes a proper basis for estimation, the taxpayer generally bears a substantial evidentiary burden to show that the method or resulting assessment is erroneous.

Bank statements, vendor invoices, and existing transaction data may help explain incomplete records. Reconstructed schedules should identify their sources and assumptions rather than appear to be original documents.

Differences between accounting records and tax returns may result from timing or classification rules. Supporting evidence should explain those differences without altering underlying transactions.

A proposed assessment may include unpaid tax, statutory interest, and penalties, each calculated under different rules.

Interest generally accrues on unpaid tax until payment. Certain penalties may qualify for reasonable-cause relief, although that relief ordinarily does not eliminate the underlying tax or interest.

Preparing documents, reconciling transactions, and answering audit requests may consume substantial employee time. Outside accounting or legal assistance can add to the expense.

Private professional fees depend on the number of periods examined, the condition of the records, and whether a formal dispute develops.

An adjustment to reported sales or income may raise questions about related returns. The department may refer findings for examination under another tax category when they affect separate reporting obligations.

A sales tax adjustment, however, does not itself establish corporation tax liability. Each tax obligation requires analysis under its own statutory rules and supporting facts.

A Statement of Proposed Audit Changes sets out adjustments that taxpayers may dispute with explanations or supporting records. The business can review the calculations, transaction classifications, and legal grounds before deciding whether to agree.

Auditors may reconsider disputed findings based on additional information. Before signing an agreement, businesses should determine which periods, issues, and amounts it resolves.

A Notice of Determination or Notice of Deficiency may provide access to the Bureau of Conciliation and Mediation Services or the Division of Tax Appeals. Many qualifying notices require a formal protest within 90 days of the date the department mails the notice, although the applicable deadline depends on the tax and notice involved.

Taxpayers may request an eligible conciliation conference online or submit Form CMS-1-MN. A qualifying petition to the Division of Tax Appeals generally uses Form TA-100.

Continuing discussions with an auditor does not extend a statutory protest deadline. Certain matters have different procedures or restrictions on prepayment hearings, so the notice and applicable law determine the available route.
