How to File Your Business Closure and Auction Proceeds with New York Tax Authorities

When a New York business concludes operations through an auction, the process of formally closing the company and reporting proceeds to state tax authorities becomes a critical final step. Compliance with the New York State Department of Taxation and Finance (DTF) ensures that outstanding obligations are cleared and that the business avoids future penalties or audits.

After the auctioneer—such as Rosen Systems, Auction Advisors, or Tiger Group—finalizes the sale, sellers receive a detailed settlement statement outlining gross proceeds, commissions, and expenses. These figures must be reported as part of the business’s final state tax filings, including sales tax, income tax, and, where applicable, corporate franchise tax. The reporting process varies based on the entity type—LLC, corporation, or sole proprietorship—but each must notify the DTF of its intent to cease operations.

For most businesses, the first step is filing a Final Sales Tax Return (Form ST-100 or ST-101), even if no taxable sales occurred in the last period. The DTF requires a final report of all taxable assets sold through the auction, including equipment, fixtures, and inventory. Auctioneers who collect sales tax on behalf of sellers—common in full-service auctions conducted by firms like Hilco Global or Apex Auctions—submit the tax directly to the state, but business owners remain responsible for ensuring all filings match reported proceeds.

Next, the business must file its final state income or corporate tax return, designating it as a final filing. For corporations, this includes submitting Form CT-3 (General Business Corporation Franchise Tax Return) or Form CT-3-S for S corporations. Partnerships and LLCs file Form IT-204 or IT-204-LL, depending on structure. The filings should reflect all income derived from the auction, including gains or losses on the sale of depreciated assets.

If the auction involved real estate or large machinery, sellers may also owe capital gains tax under New York State guidelines. These transactions must be reported on both the state and federal levels to ensure compliance with IRS Form 4797 and corresponding state adjustments.

Once all taxes are filed and paid, businesses must formally dissolve or cancel their registration with the New York Department of State (Division of Corporations). This involves filing a Certificate of Dissolution for corporations or Articles of Cancellation for LLCs. Proof of tax clearance may be required before dissolution can be accepted, particularly for entities with outstanding franchise tax liabilities.

Additionally, employers must submit final withholding reports and remit any remaining payroll taxes using Form NYS-45 through the state’s Online Services for Business portal. Businesses that maintained resale or withholding certificates must return or deactivate them to prevent future tax assessments.

For many owners, professional guidance from accountants or tax attorneys familiar with New York’s business dissolution procedures ensures a smooth transition. Firms such as Marks Paneth LLP, EisnerAmper LLP, and Grassi Advisors & Accountants frequently assist former business owners in reconciling final tax liabilities tied to liquidation or auction outcomes.

Completing these filings marks the formal close of a business’s financial and legal existence in New York. As auction-based closures continue to rise across retail, hospitality, and manufacturing sectors, proper documentation and tax reporting remain essential for ensuring compliance and protecting owners from post-closure liabilities.
