How to Get an EIN for an Estate (Indiana Executor's Guide)

For post-death estate activity, the decedent's Social Security number is not the estate's tax identifier. The estate is a separate tax entity and needs its own Employer Identification Number (EIN). Banks commonly require that EIN to open an estate account, and it is required before filing the Indiana fiduciary income tax return.

The good news: getting an EIN is free and takes about fifteen minutes online. The bad news is that dozens of third-party websites charge $60–$200 to do exactly what you can do yourself at no cost. This guide walks you through the process and explains exactly where the EIN gets used once you have it.

Why the Estate Needs Its Own EIN

An EIN is a nine-digit tax identification number the IRS assigns to entities — businesses, trusts, nonprofits, and estates. The estate of a deceased person is legally a separate entity from the person who died, and it needs its own tax ID for two core reasons.

First, income the estate earns after the date of death belongs to the estate, not the decedent. If the decedent owned a rental property and rent keeps coming in after they pass, that income flows into the estate. The estate must report that post-death estate income under its own EIN rather than the decedent's SSN.

Second, financial institutions commonly require an EIN to open an account titled in the estate's name. Estate funds such as rent, dividends, and asset-sale proceeds should be routed through that account rather than a personal account.

In Indiana specifically, the EIN is also required for filing Form IT-41, the Indiana Fiduciary Income Tax Return. You'll list the estate's EIN on every page of that form, so obtain it before filing.

Where to Apply: IRS.gov Only

Go directly to IRS.gov/ein. There is no fee. Do not use any other website.

Third-party services that charge to obtain an EIN are acting as filing agents — they submit the same IRS online form on your behalf and mark up the service. There is nothing they do that you cannot do yourself in fifteen minutes. Some of these sites have confusing names that imply government affiliation. They are not government sites. IRS.gov is the only official source.

The online EIN application is available Monday through Friday, 7 a.m. to 10 p.m. Eastern time. Once you submit, you get the EIN immediately on screen and can download an EIN confirmation letter. Print or save that letter — banks and the Indiana Department of Revenue will ask for it.

Step-by-Step: Applying Online

Step 1 — Select "Estate" as the entity type.

When the IRS application asks you to identify the type of entity, choose "Estate." Do not choose "Trust" (that applies to a separate trust arrangement) or any business entity type. The estate of a deceased individual is its own category.

Step 2 — Enter the decedent's information.

You will be asked for the legal name of the decedent exactly as it appears on their Social Security card, their Social Security number, and their date of death. This ties the EIN to the correct underlying estate.

Step 3 — Enter the responsible party.

The "responsible party" for the estate is the executor (also called personal representative). Enter your full legal name and your own SSN. You are not applying for an EIN in your name — you are identifying yourself as the person responsible for managing the estate's tax affairs.

Step 4 — Enter a mailing address.

Use the address where the IRS should send correspondence. This is typically the executor's address, since the estate itself doesn't have a physical location.

Step 5 — Complete the reason-for-application questions.

Follow the current IRS prompts for an estate's purpose. The application wording can change; do not select a business entity type for the estate.

Step 6 — Download your confirmation.

At the end, the IRS will display your new EIN immediately. Download the confirmation PDF. The number will also arrive by mail, but the online confirmation is what you need to start opening accounts and filing returns.

If you prefer to apply by fax or mail using Form SS-4, the IRS accepts those too, but the turnaround time is 4–5 business days for fax and 4–5 weeks for mail. For most estates, the online method is the right choice.

What to Do With the EIN Once You Have It

Open an estate checking account. Take the EIN confirmation letter and the decedent's death certificate to a bank. Ask to open an account titled in the name of the estate — for example, "Estate of Jane Smith." All incoming funds (asset sales, incoming rent, insurance proceeds payable to the estate) should flow through this account. All creditor payments and distributions to beneficiaries go out from it. Keeping estate funds strictly separate from your personal funds protects you as executor from personal liability claims.

File Form IT-41 with the Indiana Department of Revenue. If the estate earns $600 or more in gross income after the date of death, Indiana requires a fiduciary income tax return. You list the estate's EIN on the form. Income retained by the estate is taxed at Indiana's flat fiduciary rate of 3.23%; distributed income may pass through to beneficiaries at their individual rate, 2.95% in Indiana for 2026. The return is due by the 15th day of the fourth month following the close of the estate's taxable year.

File federal Form 1041. The federal fiduciary income tax return also requires the estate's EIN. Indiana IT-41 instructions direct you to complete the federal Form 1041 first, then attach a copy to your Indiana state filing. Having a single EIN that flows through both forms keeps everything consistent.

Pay creditors and beneficiaries. When you write checks from the estate account, having a proper EIN-registered account creates a clear paper trail. This matters if any beneficiary later disputes a distribution, or if a creditor challenges the timing of payment.

If the estate owns multiple assets — real estate, brokerage accounts, rental income, business interests — the EIN consolidates that post-death activity under one tax identity. As accounts are retitled, ask institutions to report estate income under the EIN; transition statements may still reflect the decedent's SSN.

If you're handling an Indiana estate that involves an IT-41 filing, a final IT-40 individual return for the decedent, and potential federal estate tax considerations, working through all three simultaneously takes careful coordination. The Indiana Final Tax & Estate Tax Guide at /us/indiana/estate-tax/ walks through each step in sequence — including how the EIN connects to both state and federal filings.

Common Mistakes to Avoid

Paying a third-party service. There is no legitimate reason to pay for an EIN. The IRS charges nothing, and the application takes fifteen minutes. If you land on a website asking for $79 to "process your EIN application," leave immediately.

Using the decedent's SSN for new estate activity. Some executors try to use the decedent's SSN to open estate accounts or report post-death estate income because it's easier. Use the estate's EIN for that activity; the final individual return remains a separate filing under the decedent's SSN.

Applying for the wrong entity type. If you accidentally select "Trust" instead of "Estate," you'll get a different kind of EIN. The IRS can correct this, but it creates delays. Always select "Estate" for a decedent's estate.

Applying too early or losing the confirmation. You can apply for the EIN on the day of death or any time after. There's no waiting period. Once you have it, store the confirmation letter somewhere permanent — you will reference it throughout the administration of the estate, potentially for years.

Bottom Line

Getting an EIN for an Indiana estate is free, fast, and something you can do yourself at IRS.gov in about fifteen minutes. Once you have it, everything else opens up: the estate bank account, the IT-41 fiduciary return, and the federal Form 1041. Without it, you're blocked at nearly every step of estate administration.
