What does it mean when the IRS says a tax bill is a proposed amount due based on a substitute return? - North Carolina

Short Answer

In a North Carolina probate matter, an IRS notice showing a proposed amount due based on a substitute return usually means the IRS believes the decedent did not file a required income tax return, so the IRS estimated the tax using records available to it. The amount is not necessarily final, and it may be too high if the IRS did not credit all withholding, deductions, filing status information, or other records. The personal representative should treat the notice as time-sensitive and work with a tax attorney or CPA before the response deadline.

Understanding the Problem

This question asks what a North Carolina personal representative should understand when an IRS notice for a decedent’s older tax year lists a proposed balance based on a substitute-for-return. The decision point is whether the estate should treat that IRS amount as final or investigate and respond before estate funds are distributed or the probate file is closed.

Apply the Law

A substitute-for-return is an IRS-prepared return. It usually comes up when the IRS has third-party income records, such as wage statements or retirement distribution forms, but does not have a filed return from the taxpayer for that year. In probate, the personal representative must confirm what the notice covers, whether the IRS has assessed the tax yet, and whether the estate has authority and records to respond.

The key probate point is that the IRS proposal may not reflect the decedent’s full tax picture. Missing W-2s, retirement forms, withholding records, state tax records, deductible expenses, and prior payments can change the result.

Key Requirements

IRS proposal: The notice is based on information the IRS has, not necessarily every document the decedent would have used to prepare a complete return.
Estate authority: The North Carolina personal representative should have letters from the Clerk of Superior Court and should notify the IRS of the fiduciary relationship, often by using IRS Form 56.
Record reconstruction: The estate may need IRS wage and income transcripts, account transcripts, bank records, retirement records, and state withholding information before deciding how to respond.
Deadline control: If the notice is a statutory notice of deficiency, the Tax Court deadline is commonly 90 days after the notice is mailed, and missing it can limit options.

What the Statutes Say

26 U.S.C. § 6020(b) (Returns prepared by the IRS) - allows the IRS to prepare a return using available information when a required return has not been filed.
26 U.S.C. § 6213(a) (Restrictions on assessment after deficiency notice) - generally gives 90 days, or 150 days if the notice is addressed to a person outside the United States, to petition the U.S. Tax Court after a notice of deficiency is mailed.
N.C. Gen. Stat. § 28A-19-3 (Estate claims deadlines) - sets deadlines for many claims against a North Carolina estate, although federal tax issues can involve separate federal rules.
N.C. Gen. Stat. § 105-240 (Taxes and fiduciary accounts) - addresses tax payment or security issues before a fiduciary’s final account is allowed for North Carolina tax purposes.

Analysis

Apply the Rule to the Facts: The estate has received an IRS notice for an older year and may be missing wage and retirement distribution records. That fits the common substitute-return problem: the IRS may have income reports but not the decedent’s full return information. If withholding forms, deductions, or state tax records are missing, the proposed amount should not be assumed correct until a tax attorney or CPA reviews the records and transcripts.

The personal representative should also separate the decedent’s personal income tax issue from the estate’s own tax filings. A substitute return for an older year usually concerns the decedent’s individual Form 1040. The estate may also have its own fiduciary income tax filing duties if estate income or distributions meet filing thresholds, so the response should not blur those separate returns.

Process & Timing

Who files: The duly appointed personal representative, often with help from a tax attorney or CPA. Where: The IRS office, address, fax number, or online response method listed on the notice; probate filings remain with the Clerk of Superior Court in the North Carolina county where the estate is administered. What: Letters of appointment, IRS Form 56, transcript requests, copies of available W-2s, retirement distribution forms, withholding records, and any corrected or delinquent return prepared by a tax professional. When: Follow the notice deadline; if it is a notice of deficiency, the key deadline is often 90 days after the notice is mailed.
Gather records: Request IRS account and wage-and-income transcripts, contact payors for replacement tax forms, review bank and retirement account records, and check whether any North Carolina or other state withholding appears on available documents. This step can take weeks, so it should start quickly.
Respond before distribution: The estate should respond to the IRS notice before treating the proposed balance as final, paying heirs, or closing probate. The expected outcome may be an IRS adjustment, an accepted filed return, an assessed balance, or a dispute that needs further tax representation.

Exceptions & Pitfalls

Proposed does not always mean final: Some notices invite a response before assessment. Others show that the IRS has already assessed a balance. The notice title and deadline matter.
Substitute returns may omit favorable items: Filing status, deductions, credits, basis information, and withholding can be incomplete when the IRS prepares the return from third-party reports alone.
Missing Form 56 can cause notice problems: The IRS may keep sending letters to the decedent’s last known address unless the fiduciary relationship is properly reported.
Do not rely only on family records: IRS transcripts can show income documents that the family never found, but transcripts may not prove every deduction or state withholding issue.
Do not distribute too early: Paying beneficiaries before resolving a known tax issue can create problems for the personal representative and may complicate the final probate accounting.
Do not treat this as a do-it-yourself tax decision: The estate should ask a tax attorney or CPA to decide whether to file an original return, amend a filing, request reconsideration, petition Tax Court, or pay an assessed amount.

Conclusion

When the IRS says a tax bill is a proposed amount due based on a substitute return, it means the IRS estimated the decedent’s tax from available records because it did not have a filed return for that year. In a North Carolina estate, the personal representative should not assume the amount is correct. The next step is to file a written response and any professionally prepared return or records with the IRS by the notice deadline, often 90 days after mailing for a deficiency notice.
