About NYC tax forms
Anyone who owns rent-producing property in New York City and believes their assessment may be incorrect will likely encounter forms in this category. A key example is the TC201, an income and expense schedule that must accompany a formal assessment appeal. Landlords, real estate investors, and property managers typically need these documents when challenging a property's assessed value, reporting rental income and operating expenses, or responding to Tax Commission requirements for a given assessment year.
Because these forms often require two or more years of detailed financial data and must be completed with precision, errors or omissions can undermine an appeal entirely. Tools like Instafill.ai use AI to fill these forms in under 30 seconds, helping property owners submit accurate, complete information without the usual hassle of navigating complex PDF documents.

How to Choose the Right Form
With only one form in this category, the decision is straightforward — but it's important to confirm this is the right document for your specific situation before you begin.
Who Should Use Form TC201
TC201, Income and Expense Schedule for Rent-Producing Property is designed for:
- Landlords and property owners who earn rental income from residential or nonresidential tenants in New York City
- Anyone filing an assessment appeal with the NYC Tax Commission for the 2026/27 tax year who owns income-producing real estate
- Property owners who need to provide two years of detailed financial data — including lease terms, occupancy rates, and operating expenses — to support their appeal
When TC201 Is Required
This form is not a standalone filing. You must attach TC201 to your main assessment appeal application. Do not submit it separately — it will not be accepted.
You'll need TC201 if your property:
- Generates rental income (apartments, retail spaces, mixed-use buildings, etc.)
- Is being appealed for an incorrect or over-assessed property value
- Falls under the NYC Tax Commission's jurisdiction for the current assessment cycle
When TC201 May Not Apply
- If your property is owner-occupied and does not produce rental income, a different schedule may be required for your appeal
- If you are filing for a prior assessment year (not 2026/27), confirm you are using the correct version of the form
Getting Started
TC201 requires precise financial reporting, so accuracy matters. Using an AI-powered tool like Instafill.ai can help you complete the form correctly, especially if you're working from a non-fillable PDF version that needs to be converted into an interactive format first.

Tips for NYC tax forms
The TC201 is not a standalone form — it must be filed together with your assessment appeal application to the NYC Tax Commission. Submitting it separately will render it invalid and could jeopardize your appeal. Double-check that all required attachments are included before finalizing your submission.
TC201 requires detailed income and expense figures for two consecutive years, so pulling together your records before you start filling out the form will save significant time. Have rent rolls, operating expense statements, and lease summaries on hand. Incomplete financial data is one of the most common reasons appeals are weakened or delayed.
The Tax Commission uses the figures you report on TC201 to judge whether your property's assessed value is fair, so underreporting or overreporting can hurt your case. Make sure income figures reflect actual collected rent, not just scheduled rent, and that expenses are properly categorized. Inaccurate data can undermine an otherwise valid appeal.
TC201 requires you to break out income and occupancy data by residential and nonresidential use, so mixed-use property owners should organize their records by unit type before starting. Lumping these figures together is a common mistake that can raise red flags with reviewers. Clear separation also makes your appeal easier to evaluate favorably.
AI-powered tools like Instafill.ai can fill out complex forms like TC201 quickly and accurately, saving you the time and frustration of manually working through dense financial schedules. Your data stays secure throughout the process, making it a practical choice whether you're handling one property or several. This is especially useful when working against appeal filing deadlines.
TC201 asks for specific lease information, including term lengths and tenant types, so reviewing your current leases before you begin will help you answer these sections confidently. Outdated or estimated lease data can create inconsistencies that reviewers may question. Having executed lease agreements nearby as a reference is a simple way to avoid errors.
Always save a completed copy of your TC201 and your main appeal application for your own records before submitting. If questions arise during the review process, having your submitted figures on hand lets you respond quickly and consistently. Digital copies stored securely are easiest to retrieve if needed later.
