How Does a New York Corporate Tax Attorney Review State Tax Exposure?

Start with the company’s legal form and tax classification. An LLC taxed as a partnership follows different filing rules from an LLC taxed as a corporation. A federal S election does not automatically establish state S corporation treatment.

Check:

• Where the corporation was formed.
• Where employees work and what they do.
• Where the business holds inventory or other property.
• When those activities began.

A New York corporate tax attorney can use these records to identify affected tax years. Businesses operating across several jurisdictions may also need a broader state and local tax review.

For tax years beginning in 2026, the economic nexus threshold is $1,283,000 in New York receipts. Nexus means a connection that permits the state to impose a tax obligation.

Receipts below that amount do not establish an exemption. Physical operations or other connections may create liability. Certain related corporations must also apply group aggregation rules.

Federal Public Law 86-272 limits certain state net income taxes when in-state activity consists of qualifying solicitation of orders for tangible goods. Orders must be approved and filled from outside the state. Service revenue does not generally qualify for this protection.

A company should not assign its entire revenue stream using one customer address. Different transactions can require different location evidence.

Digital products, financial transactions, and certain industries have separate rules. Classify the receipt before choosing its location.

A billing address may differ from the delivery location or the place where a customer receives a service’s benefit. The employee’s work location does not automatically control service-receipt sourcing.

Useful checks include:

• Matching invoices to delivery records.
• Reading contracts to identify the service and its users.
• Reviewing customer use across several locations.
• Recording inquiries made to resolve missing location information.

Follow the required order of sourcing methods. Where the rules permit reasonable approximation, keep the records and assumptions supporting that approach.

Compare the filed return with the worksheets used to prepare it. Identify which entry changed the amount due.

Review:

• State receipts and total receipts used in apportionment.
• Adjustments between federal income and the state tax base.
• Credits, estimated payments, and account balances.
• Entities included in a combined return, where applicable.

When an auditor changes these figures, request the supporting workpapers. Explain the disputed entry and connect each objection to a record or legal rule.

If the company overpaid, corporate tax refund review requires a separate claim and deadline analysis.

Use the forms and rules for the year under review. A payment rule that applies now may differ from the rule governing an earlier return.

For tax years beginning in 2026, Article 9-A C corporations generally must make quarterly estimated payments if expected tax after credits reaches $5,000. Mandatory first installments use a separate historical-tax test.

Article 9-A S corporations have no estimated franchise tax payment requirement for these years. Separate shareholder payment duties may still apply.

Also check for an MTA surcharge. Activity and receipts within the Metropolitan Commuter Transportation District require their own analysis.

An auditor’s proposed adjustment differs from a formal Notice of Deficiency. An objection made during the audit does not replace a required formal protest.

For a notice carrying protest rights:

• Check the mailing date and stated deadline.
• Identify the tax years and amounts disputed.
• Keep the notice, envelope, and filing confirmation.

The protest period is generally 90 days, subject to the applicable notice and statute. Further discussions with the auditor do not extend that deadline. Not every bill provides a right to a hearing before payment.

A business with protest rights may request a conference through the Bureau of Conciliation and Mediation Services, known as BCMS. Alternatively, it may petition the Division of Tax Appeals.

Eligible BCMS requests can be submitted through Online Services or Form CMS-1-MN. A formal tax appeals hearing generally proceeds before an administrative law judge, with further review available through the Tax Appeals Tribunal.

Judicial review of a Tribunal decision goes to the Appellate Division, Third Department. The four-month period runs from the decision’s issuance and notice to the parties. Payment or bond requirements also need review.

A separate IRS collection letter follows federal procedures. Review IRS bank levy notices separately from the state assessment.

Yes. A business loss does not necessarily eliminate franchise tax. Depending on the corporation and tax year, a capital-based tax or fixed dollar minimum may still apply.

No. City liability requires a separate analysis. Federal S corporations may owe the city’s General Corporation Tax even when they receive S corporation treatment at the state level.
