How to Choose the Right Form
Income and expense forms are critical legal documents used to provide a snapshot of your financial health. Because these forms are specific to certain jurisdictions and legal matters, choosing the right one depends entirely on your current situation.
Family Law and Support Obligations
In matters of divorce, child support, or spousal maintenance, courts require a detailed breakdown of your finances to ensure fair rulings. These forms are used to determine ability to pay and the necessity of support orders.
- California Cases: You should use Form FL-150, Income and Expense Declaration. This is the standard Judicial Council form used across California to declare income, assets, and monthly living expenses under penalty of perjury.
- Ohio Cases: If your case is in the Ohio Court of Common Pleas, you will need the Uniform Domestic Relations Form – Affidavit 1 (Affidavit of Basic Information, Income, and Expenses) for a sworn statement of your financial data.
New York City Property Tax Assessments
Property owners in New York City often need to report financial data to appeal property tax valuations. This helps the Tax Commission evaluate if a property's assessed value is appropriate.
- NYC Property Owners: Use Form TC201, Income and Expense Schedule for Rent Producing Properties. This form is a mandatory attachment for assessment appeal applications and covers detailed income and expense data for both residential and non-residential rent-producing properties for the 2026/27 assessment year.
Student Loan Management
If you are dealing with defaulted federal student loans, specific forms are required to negotiate payment terms based on what you can actually afford.
- Federal Student Loan Borrowers: Choose the Loan Rehabilitation: Income and Expense Information form. This is used for the William D. Ford Federal Direct Loan or FFEL programs to help establish an affordable, alternative payment plan based on your documented income and expenses rather than a standard formula.

Tips for income expense forms
To ensure accuracy, have your most recent pay stubs, tax returns, and bank statements ready. These forms often require precise figures for utilities, insurance, and miscellaneous expenses that are difficult to estimate from memory.
A frequent error on forms like the FL-150 is reporting take-home pay instead of gross income. Always check the instructions to see if the court or agency requires the amount before or after taxes and deductions to avoid filing errors.
AI-powered tools like Instafill.ai can complete these complex income and expense forms in under 30 seconds with high accuracy. Your sensitive financial data stays secure during the process, making it a highly efficient and safe way to handle multiple filings.
For forms like the NYC TC201, ensure you itemize all operating costs, including repairs, management fees, and utilities. Accurate reporting is essential for the Tax Commission to evaluate property assessments and potentially lower your tax burden.
Ensure the income figures you report match your most recent state or federal tax returns. Discrepancies between these forms and your tax history can trigger audits or cause delays in court proceedings and loan rehabilitation approvals.
Many family law and loan rehabilitation forms require you to list income or financial contributions from other adults in the household. Omitting this information can lead to a rejection of the form or a loss of credibility during legal hearings.
