Form IT-205-A Instructions: New York Fiduciary Allocation (Tax Year 2025)

Form IT-205-A is the New York State schedule that fiduciaries use to allocate income among resident and nonresident beneficiaries, and between New York and non-New York sources, when an estate or trust has a mix of both. The IT205AI document is simply the official instruction booklet published by the New York State Department of Taxation and Finance to help preparers fill out that schedule correctly for tax year 2025. If you’re already working on the main return, it pairs directly with the fiduciary income tax filing itself.

These instructions are not a form you fill in yourself — they’re the guide that walks you through completing Form IT-205-A, line by line. They explain how to compute each beneficiary’s share of federal distributable net income, how to separate New York source income from income earned outside the state, and how to handle situations where a trust has both resident and nonresident beneficiaries during the same tax year.

Who needs this form

Fiduciaries — meaning executors, administrators, or trustees — are the ones responsible for this filing. You’ll need Form IT-205-A, and therefore these instructions, if the estate or trust you’re managing has at least one nonresident beneficiary and the trust or estate has income from New York sources. It also applies when a resident trust becomes a nonresident trust (or vice versa) partway through the year, since income has to be allocated between the two periods.

If every beneficiary is a New York resident and all income is New York source income, this allocation schedule generally isn’t necessary. The complexity only kicks in once beneficiaries or income sources cross state lines.

When it’s used

This allocation is completed as part of the annual fiduciary income tax filing, alongside Form IT-205, the New York State Fiduciary Income Tax Return. The instructions in IT205AI are meant to be referenced while preparing that return, not filed on their own. Fiduciaries typically pull together trust accounting records, K-1 equivalents, and income source documentation before sitting down to work through the allocation calculations described in the booklet.

Because the allocation affects how much each beneficiary reports as New York source income on their own personal returns, getting this schedule right matters beyond just the fiduciary return. Beneficiaries rely on the fiduciary’s allocation when preparing forms like IT-201 for residents or the nonresident equivalent, so accuracy here has downstream consequences.

How to get and complete it

The IT205AI instructions are available directly from the New York State Department of Taxation and Finance as a PDF. This is not a fillable digital form — there are no interactive fields to type into. You’ll need to download and print the document, then complete the corresponding Form IT-205-A schedule by hand using the guidance provided.

Working through it usually involves these steps:

• Gather the estate or trust’s full income statement, broken out by source (New York vs. non-New York).
• Identify each beneficiary and their residency status for the tax year, noting any changes in residency that occurred mid-year.
• Follow the line-by-line instructions to calculate each beneficiary’s proportional share of distributable net income.
• Transfer the completed allocation figures onto Form IT-205-A, and then onto the main IT-205 return.
• Keep a copy with the trust’s records, since beneficiaries may request supporting documentation for their own filings.

If the fiduciary situation is complicated — multiple beneficiaries, partial-year residency changes, or income from several out-of-state sources — it’s worth reading through the full instructions booklet slowly rather than skipping to the form itself. The examples in the New York guidance often clarify allocation methods that aren’t obvious just from the form’s column headers. For fiduciaries who also handle estimated tax obligations for the trust, it can help to cross-reference this with Form IT-2105.9 guidance to avoid underpayment issues tied to misallocated income.
