NY Tax Form IT-203F: Multi-Year Allocation Form


Tax obligations may become especially challenging for individuals who have relocated between states, especially when dealing with complex income sources such as stock options and other forms of equity compensation. For part-year residents or nonresidents of New York State who have received income from such sources, the NY Tax Form IT-203F is an essential document. This form is specifically designed to ensure that income earned from equity compensation while a person resided or worked in New York is appropriately allocated to the state, even if the actual payment is received after moving.

Equity compensation often spans multiple years, creating a need for precise income allocation to comply with state tax laws. Proper completion of Form IT-203F is vital for taxpayers to meet their legal obligations and avoid potential penalties. 

New York State Tax Law, specifically Section 601(e), outlines the requirement for taxpayers to allocate income derived from services performed within the state. This regulation applies regardless of the taxpayer’s residency status at the time of income receipt, emphasizing the need for accurate income reporting on Form IT-203F.

NY Tax Form IT-203F

Form IT-203F is used by part-year residents and nonresidents of New York State to allocate income over multiple years. This form is particularly relevant for individuals who have received compensation in the form of stock options, restricted stock, or stock appreciation rights that span several tax years. The form ensures that New York State receives its fair share of taxes on income that was earned while the taxpayer resided in the state, even if the income is received after moving out.

The regulation governing the multiyear allocation of equity compensation is detailed in the New York State Tax Law, Section 601(e). This law mandates that income earned while performing services in New York State must be taxed by New York, regardless of the taxpayer’s residency status when the income is actually received.

Form IT-203F should be completed by:

  • Individuals who were part-year residents of New York State.
  • Nonresidents who earned income in New York State from stock options, restricted stock or stock appreciation rights.
  • Taxpayers who moved out of New York State but received compensation for work performed while they were residents or working in New York.

Process Steps for NY Tax Form IT-203F

Filing NY Tax Form IT-203F involves several detailed steps to ensure proper allocation of multiyear income. Here’s an in-depth guide to each stage of the process:

  1. Gathering Relevant Information
    • Equity Compensation Documentation: All relevant documents related to the stock options, restricted stock and stock appreciation rights should be collected. This includes grant agreements, vesting schedules and exercise records.
    • Employment Records: Records that specify the periods the taxpayer worked in New York State and the nature of the employment must be obtained. This is important for determining the allocation period and ensuring accurate reporting.
  2. Determining the Allocation Period
    • Identifying Service Periods: The specific periods during which the equity compensation was earned versus when it was received should be established. Equity compensation such as stock options, often spans multiple years and may include pre-grant, vesting and post-vesting periods.
    • Residency Status: The residency status during these periods should be determined. The dates the taxpayer was a part-year resident or nonresident of New York State should be determined.
  3. Completing Schedule A: Allocation of Non-Stock Option Income
    • Income Allocation: Schedule A is used to allocate non-stock option income related to employment in New York State. This includes compensation from termination agreements or covenants not to compete.
    • Income Breakdown: A breakdown of income earned during the period the taxpayer was a resident and a nonresident of New York must be provided. The proportion of income attributable to New York State based on the days worked in New York versus other locations must be calculated.
  4. Completing Schedule B: Allocation of Stock Option and Equity Compensation Income
    • Stock Option Allocation: Schedule B focuses on income from stock options, restricted stock and stock appreciation rights. The portion of this income attributable to services performed in New York State should be calculated.
    • Formulas and Methods: The formulas and methods provided in the IT-203F instructions should be used to allocate stock option income. This typically involves prorating the income based on the number of days worked in New York during the vesting period.
  5. Calculating the Taxable Income
    • Combining Schedules A and B: The allocated income from Schedules A and B should be added to determine the total income attributable to New York State.
    • Adjusting for Deductions and Credits: The allocated income should be adjusted for any applicable deductions and credits specific to New York State. This might include state-specific adjustments that differ from federal deductions
  6. Filing the Form
    • Attaching Form IT-203F to IT-203: Once Form IT-203F is completed, it should be attached to Form IT-203, Nonresident and Part-Year Resident Income Tax Return. It should be ensured that all required schedules and supporting documents are included.
    • Electronic Filing: E-filing the return must be considered for faster processing and confirmation. Approved tax software must be used to file both forms electronically.
  7. Professional Assistance
    • Consulting a Tax Professional: Given the complexities involved in allocating multiyear income, consulting a tax professional is advisable. A CPA or tax advisor can help ensure accuracy and compliance with the tax laws.

Example Calculation and Application

To illustrate the process, consider an example where an individual worked in New York State for three years before moving to another state. The individual received stock options during their employment, which vested over a four-year period, extending into the time after they relocated.

  1. Determine the Allocation Period: Identify the specific dates the stock options were granted and vested. Suppose the options were granted on January 1, 2020, and vested annually over four years.
  2. Calculate Days Worked in NY: Calculate the number of days worked in New York during the vesting period. For instance, if the individual worked in New York for two years before moving and the options vested over four years, 50% of the income from these options would be attributable to New York.
  3. Allocate Income: Use the proportion of days worked in New York to allocate the income from the stock options. If the total income from the options was $100,000, $50,000 would be reported on Form IT-203F as attributable to New York State.
