Oregon Fiduciary Income Tax: Form OR-41 Guide for Estates

The moment a person dies in Oregon, their estate becomes a separate taxpayer. Until the estate is fully distributed and closed, any income those assets earn — rental income, dividends, capital gains — doesn't belong to the deceased person and doesn't go on their final individual return. It belongs to the estate, and the estate must report it on Form OR-41, the Oregon Fiduciary Income Tax return.

Most personal representatives don't know this return exists until a brokerage statement arrives addressed to the estate of their loved one. By then, deadlines may already be pressing.

What Is a Fiduciary Income Tax Return?

A fiduciary income tax return reports the taxable income earned by a trust or estate during administration. In Oregon, the form is OR-41. It's the state equivalent of the federal Form 1041.

The personal representative (executor) acts as the fiduciary — the person legally responsible for collecting income, paying expenses, and reporting everything to the Oregon Department of Revenue. This is a separate obligation from:

• The deceased person's final individual return (Form OR-40, covering income up to the date of death)
• The Oregon estate transfer tax return (Form OR-706, if the gross estate exceeds $1,000,000)

Form OR-41 covers the income generated by estate assets after the date of death, during the probate administration period.

When Must Oregon Estates File Form OR-41?

An Oregon probate estate must file Form OR-41 if:

• The estate (or ancillary Oregon estate) has federal gross income of $600 or more during the tax year, or
• A nonresident estate generates $600 or more from Oregon sources

If the estate earns less than $600 in a given year — say, only modest interest on an estate checking account — the return is not mandatory. However, one important exception overrides this threshold: the Oregon kicker credit (more on this below).

There is also a practical trigger: if the personal representative elects a fiscal tax year for the estate rather than a calendar year, they must file Form OR-41 to establish that election, even if the estate earns nothing in its first abbreviated tax period. Choosing a fiscal year end (for example, January 31) gives the estate up to 11 months of flexibility for deferring income distributions to beneficiaries and managing their personal tax exposure.

What Income Goes on Form OR-41?

Everything the estate's assets earn from the day after the date of death until the estate is closed:

• Interest and dividends from bank and brokerage accounts
• Rental income from real property the estate holds during administration
• Capital gains from selling estate assets (a house, investments, a vehicle)
• Business income if the decedent owned a pass-through entity that the estate continues to operate
• Refund of the decedent's overpaid income taxes, if the refund arrives after death

Oregon's fiduciary income tax rates are compressed — income retained in the estate is taxed at higher rates than it would be in the hands of most individual beneficiaries. This creates an incentive to distribute income to heirs rather than accumulate it in the estate. When income is distributed, the estate issues Oregon-adjusted Schedule K-1 statements to each beneficiary, shifting the tax obligation to their personal returns.

Key Oregon-Specific Adjustments on Form OR-41

Oregon follows federal tax law as of December 31, 2023. This creates several disconnects that fiduciaries must address using Schedule OR-ASC-FID (additions and subtractions):

The Qualified Business Income (QBI) deduction must be added back. If the estate claims the federal Section 199A QBI deduction on Form 1041, that deduction is disallowed for Oregon purposes. The personal representative must add it back using addition code 185. Failing to do this is a common audit trigger.

Section 529 plan withdrawals. If the decedent or the estate withdraws from an Oregon 529 college savings plan for K-12 tuition — and those prior contributions were subtracted from Oregon taxable income — the withdrawal must be added back using code 117.

IRC Section 645 election. Oregon recognizes the federal Section 645 election, which lets a qualified revocable trust be treated as part of the probate estate for tax purposes. If the decedent had a revocable living trust, the personal representative and trustee can make this election (using Form 8855 at the federal level) so they file a single combined return rather than separate returns. To make the Oregon election, check the "trust filing as an estate" box on Form OR-41 and attach a copy of Form 8855 and the death certificate.

Nonresident fiduciaries. If the estate is a nonresident estate (the decedent was not an Oregon resident but owned Oregon property), the fiduciary must prepare a "pro forma" mock federal Form 1041 using only Oregon-source income and deductions, labeled "Oregon-source income" across the top. The Oregon taxable income is derived from this document.

The Oregon Kicker Credit — Don't Miss It

Oregon's "kicker" is a surplus refund the state pays to taxpayers when revenue exceeds forecasts. For the 2025 tax year, the kicker is set at 9.863% of the estate's 2024 Oregon tax liability before credits.

This credit is fully refundable — the estate can receive a cash payment even if it owes zero tax in 2025. The key is that a personal representative must actively file a 2025 Form OR-41 to claim the credit on line 19, even if the estate closed before year-end or earned less than $600 during 2025.

An estate that generated $2,000 in 2024 Oregon fiduciary income and paid $100 in Oregon tax would be eligible for a kicker refund of roughly $10. That's a small example — but for estates with significant income in 2024 and that have since closed or reduced activity, the refund can be meaningful.

The personal representative also has the option to irrevocably donate the kicker refund to the Oregon State School Fund. To do this, enter zero on line 19 and check the donation box.

Distributing Income to Beneficiaries: The K-1 Process

When the personal representative distributes estate income to heirs, that income shifts from the estate's tax return to the beneficiaries' personal returns. The distribution is reported on:

• The estate's Form OR-41 (deducted from estate income)
• Oregon Schedule K-1 issued to each beneficiary (showing their share of distributed income and Oregon-specific adjustments)

Beneficiaries receiving an Oregon Schedule K-1 must report that income on their personal Oregon tax return for the year, regardless of what state they live in (for Oregon-source income). Non-Oregon beneficiaries should check with their home state's tax authority about whether they also owe state income tax on distributed estate income from Oregon.

Filing Deadline and Extension

Form OR-41 is due on the 15th day of the fourth month following the close of the estate's tax year. For a calendar-year estate, that's April 15. For an estate with a fiscal year ending January 31, the return would be due May 15.

Oregon accepts a federal extension for fiduciary returns — if you file a federal Form 7004 extension, Oregon automatically grants a corresponding extension. The extended deadline is typically the 15th day of the tenth month following the tax year close.

When to Get a CPA Involved

Form OR-41 is not a simple return. The addition/subtraction adjustments, the decision about fiscal year elections, the QBI add-back, and the mechanics of issuing Oregon-adjusted K-1s to beneficiaries all require attention to Oregon-specific rules that differ from the federal return.

If the estate holds income-generating assets — any real estate, a business interest, a significant investment portfolio — bring in an Oregon CPA early. The cost of professional preparation is typically deductible on the estate's return, and the risk of errors that trigger penalties or audits is significantly reduced.

The Oregon Final Tax & Estate Tax Guide covers Form OR-41 in sequence alongside the final OR-40 and Form OR-706, with a chronological checklist for managing all three filings during the administration period.
