Form IT-663 Instructions: Commercial Security Credit (Tax Year 2025) Explained

Form IT-663 is the instructional companion to New York State’s Commercial Security Credit, a tax credit designed to help small businesses offset the cost of installing security equipment at their retail locations. The New York State Department of Taxation and Finance issues this form each year, and the IT663I version covers claims filed for tax year 2025. If you run a store, pharmacy, or other retail operation in New York and spent money on cameras, alarm systems, or other loss-prevention equipment, this is the guidance document you need before you sit down with the actual credit form.

The credit itself responds to a real problem many retailers have faced in recent years: rising costs tied to theft and vandalism. Rather than leaving business owners to absorb those costs alone, New York allows eligible taxpayers to claim a credit against qualified security investments. The instructions in IT663I walk through exactly what counts as a qualifying expense, how the credit is calculated, and what documentation you should keep on hand if the Tax Department ever asks for proof.

Who Needs This Form

This form is aimed at small business owners operating a retail location in New York State. If your business installed or upgraded security systems, purchased surveillance cameras, added alarm monitoring, or made other qualifying security improvements during the tax year, you likely need to review these instructions before completing the corresponding credit claim form. The instructions clarify eligibility rules, including business size limits, the types of retail operations that qualify, and caps on the total credit amount a single taxpayer can claim.

Sole proprietors, partnerships, and corporations that meet the retail business definition under New York tax law can all potentially claim this credit, though the instructions spell out different reporting requirements depending on your business structure. Partners and shareholders in pass-through entities will find specific guidance on how the credit flows through to their individual returns.

When and How the Credit Applies

The Commercial Security Credit applies to qualifying purchases and installations made during the applicable tax year, in this case 2025. The instructions explain the calculation method, which is typically based on a percentage of qualified expenditures up to a set dollar limit. They also cover carryover rules in case your credit exceeds your tax liability for the year, and they note any recapture provisions that could apply if equipment is removed or the business closes shortly after claiming the credit.

Because this is a paper-only form, you’ll need to print it and complete it by hand rather than filling it in digitally. That means gathering your receipts, invoices, and any vendor documentation before you start, so you can transfer the correct figures onto the form without having to stop and search for records midway through.

Getting and Completing the Form

You can download the official instructions directly from the New York State Department of Taxation and Finance website. Once printed, read through the eligibility section first to confirm your business and expenses qualify before working through the calculation worksheets. Keep a copy of everything you submit, along with your supporting documentation, in case the department requests verification later.

New York offers several other targeted business credits worth reviewing alongside this one. Businesses investing in workforce development, for example, may want to look at the Form IT-669 instructions for the Semiconductor Manufacturing Workforce Training Program Credit, while employers offering childcare benefits should check the Form IT-652 instructions for the Employer-Provided Childcare Credit. Media companies, meanwhile, may find relevant details in the Form IT-665 instructions for the Newspaper and Broadcast Media Jobs Credit. Reviewing these related credits can help you spot other opportunities to reduce your New York State tax liability beyond just security improvements.
