Form IT-611I: Instructions for Form IT-611 Claim for Brownfield Redevelopment Tax Credit (Tax Year 2025)

Form IT-611I is the instruction booklet the New York State Department of Taxation and Finance publishes alongside Form IT-611, Claim for Brownfield Redevelopment Tax Credit. This credit exists to reward taxpayers who take on the cost and risk of cleaning up and redeveloping contaminated sites in New York State. If you’re a business or individual taxpayer who participated in the state’s Brownfield Cleanup Program (BCP) and received a Certificate of Completion for a qualified site, this is the form that lets you claim the tax benefit tied to that work.

The brownfield credit isn’t a single flat amount. It’s actually made up of three components: the site preparation credit component, the on-site groundwater remediation credit component, and the tangible property credit component. Each one covers different costs related to remediating and redeveloping a brownfield site. Form IT-611 walks you through calculating each component separately before combining them into your total credit claim. The instructions in IT-611I explain exactly which costs qualify for each component, how to apply the applicable percentages, and how site preparation costs differ from tangible property costs for credit purposes.

Who Needs This Form

This form is specifically for taxpayers whose brownfield sites were accepted into the Brownfield Cleanup Program under an agreement executed before June 23, 2008, and where remediation was substantially complete by a certain date under the older program rules. New York has revised its brownfield credit rules multiple times over the years, and IT-611 corresponds to the original BCP framework rather than the newer BCP tax credit rules used for later site acceptances. If your Brownfield Site Cleanup Agreement was executed on or after June 23, 2008, you’ll likely need a different form (such as IT-611.1 or IT-611.2, depending on your acceptance date), so it’s worth double-checking your Certificate of Completion date and agreement date against the eligibility notes in the instructions before you start filling anything out.

Typically, this applies to corporations, partnerships, and individual taxpayers who were directly involved in remediating and developing a qualified brownfield site, either as the original applicant or as a taxpayer who acquired an interest in the site after remediation. Partners, shareholders, and members of pass-through entities that hold the credit will also use related schedules referenced in the instructions to claim their share.

When You’d Use It

You file Form IT-611 for the tax year in which you’re claiming the credit, which generally follows the year you received your Certificate of Completion from the Department of Environmental Conservation, though the credit can be claimed over multiple years depending on when qualifying costs were incurred. Because brownfield redevelopment projects often span several tax years, taxpayers frequently need to reference this form repeatedly as different phases of a project are completed and different cost categories become eligible for the credit.

How to Get and Complete the Form

Form IT-611 and its instructions are available directly from the New York State Department of Taxation and Finance’s forms library as a PDF. Importantly, this form is not fillable online — there are no digital form fields to type into. You’ll need to print the PDF and complete it by hand, then attach it to your New York State income tax return when you file. Make sure you’re using the version specific to tax year 2025, since credit calculation percentages and cost caps can change from year to year.

Before filling it out, gather your Certificate of Completion, records of remediation and development costs, and any prior-year credit carryforward information if you’re continuing to claim the credit from an earlier project phase. The instructions include worksheets for each credit component, so it helps to organize your expense documentation by category (site preparation, groundwater remediation, tangible property) before you start writing numbers on the form.

If you’re also researching other New York State credits and adjustments, you might find it useful to look at Form IT-604I for the QEZE Tax Reduction Credit, which covers a different type of economic development incentive, or Form IT-270I for the NYC Income Tax Elimination Credit if you’re filing a New York City return alongside your state return. Taxpayers dealing with other specialized New York credits or relief provisions, such as the special rules covered in Form IT-59 instructions for 9/11 victim tax forgiveness, may also want to keep that reference handy since brownfield credit claims sometimes intersect with other state tax relief filings depending on a taxpayer’s overall situation.

Once completed, attach Form IT-611 to your applicable New York State tax return (IT-201, IT-203, or a corporate franchise tax return, depending on your filing type). Keep copies of your Certificate of Completion and all supporting cost documentation, since the Department of Taxation and Finance can request this backup if your claim is reviewed.
