Form IT-612: Claim for Remediated Brownfield Credit for Real Property Taxes (Tax Year 2025)

Form IT-612 is used by New York State property owners who have completed cleanup of a contaminated site to claim a credit against the real property taxes they pay on that site. The credit is part of New York’s Brownfield Cleanup Program, which encourages private investment in cleaning up and redeveloping polluted or underused industrial land. If you own qualified property that has received a Certificate of Completion under the Brownfield Cleanup Program, this form lets you recover a portion of the real property taxes paid during the tax year.

The New York State Department of Taxation and Finance issues this credit as an incentive tied directly to remediation work, not just ownership. You’re not eligible simply because you own land in a designated brownfield area — the property must have gone through the formal cleanup process administered by the Department of Environmental Conservation, and you need documentation confirming that the site meets the required cleanup standards.

Who Needs to File Form IT-612

This form applies to individuals, corporations, partnerships, and other business entities that own real property within a qualifying brownfield site in New York State. Typically, the filers are developers, manufacturers, or investors who purchased contaminated land at a reduced price, funded the environmental remediation, and now own or lease property that generates real property tax liability.

To claim the credit, you generally need to show:

• A valid Certificate of Completion issued by the Department of Environmental Conservation for the qualified site
• Real property tax payments made during the tax year for the eligible property
• The site remains within the compliance period specified for continued credit eligibility

Because brownfield credits are often claimed alongside other environmental and business incentive credits, some filers also work with forms like Form IT-613, which covers environmental remediation insurance costs. If your remediation project involved multiple phases of tax incentives, reviewing both forms together can help you avoid missing eligible credits.

When This Form Is Used

You file Form IT-612 with your New York State income tax return for the tax year in which the real property taxes were paid on the qualified site. The credit is calculated based on a percentage of eligible real property taxes, and the percentage can vary depending on when the site received its Certificate of Completion and which compliance period applies. Since brownfield credits phase out over time and rules have been updated across different legislative sessions, it’s worth double-checking the specific year’s instructions attached to the 2025 version of the form rather than relying on older guidance.

Property owners typically file this form annually for as long as the site remains within its eligible compliance period, which can span multiple tax years depending on when remediation was completed.

How to Fill Out and File Form IT-612

The 2025 version of Form IT-612 is a fillable PDF, so you can complete it digitally before printing or attaching it to your electronic return. The form asks for identifying information about the property, the site’s BCP (Brownfield Cleanup Program) site number, the Certificate of Completion date, and a breakdown of the real property taxes paid during the year. You’ll need to calculate the credit percentage based on the applicable compliance period and apply it to the qualified tax amount.

Supporting documentation — including your Certificate of Completion and property tax bills — should be kept with your records in case the Department of Taxation and Finance requests verification. The form itself doesn’t require you to submit these documents upfront, but you’ll want them on hand.

If your business has claimed other New York tax credits related to workforce or facility investment, it may also be worth reviewing programs such as the credit covered in Form IT-607 or the training-related credit described in Form IT-631, since businesses undergoing redevelopment often qualify for more than one incentive in the same filing year.

Once completed, Form IT-612 is submitted along with your applicable New York State tax return — not filed separately. Make sure the credit amount calculated on this form is carried over correctly to the appropriate line on your main return, since errors in transferring totals are one of the most common reasons these claims get delayed or adjusted by the state.
