When the estate itself owes income tax

After · 8 min read

Once someone dies, anything their property earns belongs to the estate rather than to them, and the estate becomes a separate taxpayer. If the estate takes in more than $600 of gross income in a year, it must file Form 1041, the income tax return for estates and trusts. Before you can file, the estate needs its own employer identification number, which is free and can be obtained from the Internal Revenue Service online. The estate may use a calendar year or a fiscal year, and a five month extension is available on Form 7004. Income the estate passes out to beneficiaries is reported to them on a Schedule K-1 and is generally taxed to them rather than to the estate.

Why it exists

An estate is a temporary legal person. It exists from the death until the final distribution, and during that window the house may be rented, the portfolio may pay dividends, and the savings account may earn interest. That income has to be taxed to someone, and the estate is who.

Separating the estate from the individual also protects the accounting. Once the employer identification number exists and the estate has its own bank account, every dollar in and out is traceable. That record is what the beneficiaries and the probate court will eventually want to see.

The $600 threshold exists to keep small estates out of the system. Many estates that close quickly never earn that much and never file. The threshold is about the estate's gross income, though, not about the size of the estate, so a large estate that is distributed fast may file nothing while a modest one that stays open for two years may file twice.

How it actually works

Get an employer identification number for the estate first. It is free from the Internal Revenue Service, available online, and nothing else can proceed without it: not the estate bank account, not the brokerage retitling, not the return. Then file Form 56 to notify the Internal Revenue Service of the fiduciary relationship, which Publication 559 directs the representative to do as soon as the necessary information including the employer identification number is available.

Work out whether the threshold is met. Form 1041 is required where the estate has more than $600 of gross income for the year. Gross income means what came in before deductions, so a rental property grossing above the threshold triggers a filing even where expenses swallow the profit.

Choose the tax year. An estate may adopt a calendar year or a fiscal year, which is an option individuals do not have and which can be genuinely useful for spreading income across two tax years. For a calendar year estate, the return is due on April 15 following the year the income was earned. For a fiscal year, it is due the fifteenth day of the fourth month after the tax year closes. Form 7004 gives an automatic five month extension.

Distribute and report. Where the estate pays income out to beneficiaries during the year, it generally takes a deduction and issues each beneficiary a Schedule K-1 showing their share, which they report on their own return. This is why beneficiaries sometimes receive a tax form for money they thought was simply an inheritance. The inheritance itself is not taxable income to them, but income the estate earned and passed on is.

Where you stand

You are entitled, as personal representative, to pay the estate's taxes from estate funds before distributing anything. That is not merely permitted, it is the order the law expects. Distributing first and discovering a tax bill later is how representatives end up personally exposed.

You are entitled to choose the fiscal year. This is one of the few genuinely useful discretionary choices in estate administration, and it is worth a conversation with an accountant before the first return, because it cannot easily be undone afterward.

You are entitled to notice and to correspondence. Filing Form 56 makes you the person the Internal Revenue Service writes to about the estate. Without it, notices may go to the deceased person's last known address, which is often a house that has been emptied and sold.

State rules vary. States with an income tax generally have their own fiduciary return with their own thresholds and deadlines, and a few tax the estate based on where the beneficiaries live rather than where the deceased person lived. Confirm with your state department of revenue rather than assuming the federal answer applies.

What to do

The mistakes that cost people

  • Using the deceased person's Social Security number for estate accounts. The estate needs its own employer identification number, and the mismatch produces notices that take months to unwind.
  • Missing the threshold because you measured net income. The test is gross income, so a property that grosses above $600 triggers a filing even when it loses money.
  • Distributing everything before the final return is filed, then discovering the estate owes tax and the money is gone.
  • Surprising a beneficiary with a Schedule K-1 in February. Telling them in advance costs one phone call and avoids a difficult conversation.

Words you will meet

form 1041
The federal income tax return an estate or trust files on income it earned after the death.
employer identification number
The estate's own federal tax number, free from the Internal Revenue Service, needed before the estate can open accounts or file returns.

fiscal year
A tax year ending on the last day of a month other than December, which an estate may adopt but an individual may not.

What this does not cover

This module does not cover trust income tax returns, which use the same form but follow different distribution rules, or the federal estate tax, which is a tax on the transfer of wealth rather than on income. Both are separate.
