Here is a question that sounds technical but decides cases: when the IRS denies equitable innocent spouse relief and you go to the Tax Court, does the judge decide the question fresh, or just check whether the IRS was unreasonable? Porter v. Commissioner is where the Tax Court answered that it decides fresh.
The Facts
Suzanne Porter lived in Maryland. She held a business administration degree, married John Porter in 1994, and had two children with him. In 2002 she was wrongfully discharged from a federal government job and worked for a time as a bus driver.
The couple kept separate checking accounts and credit cards. She did not review his bank statements or pick up the mail. He paid the mortgage and car insurance; she paid everything else, including groceries, with her credit cards. In 2003 she received $24,285 in wages and unemployment compensation. He earned $12,765 in nonemployee compensation and took a $10,700 distribution from his IRA. He refused to tell her about his 2003 income, and she did not know about the distribution when it was made.
He prepared their joint 2003 return. It reported the IRA distribution and her income but not his nonemployee compensation. He handed it to her to sign on April 15, 2004, the due date, pressing her to sign quickly. She checked that her own income was right and signed. Six days later, on April 21, 2004, they legally separated.
The IRS issued notices of deficiency adding his $12,765 and a 10 percent additional tax of $1,070 on the early IRA distribution under IRC § 72(t)(1). She requested innocent spouse relief. Appeals granted relief under § 6015(c) on the unreported compensation, but denied relief on the $1,070 additional tax, finding she knew or had reason to know it was not reported. In January 2007, because of debt from the marriage, she filed for bankruptcy.
The Issue
In a § 6015(f) case, should the Tax Court review the IRS's denial for abuse of discretion or decide the question de novo? And was Porter entitled to relief?
The Holding
Judge Haines wrote: "in cases brought under section 6015(f) we now apply a de novo standard of review as well as a de novo scope of review." Applying that standard, the Court held Porter was entitled to equitable relief and entered decision for her.
The Reasoning
Why the old standard existed
When Congress enacted § 6015 in 1998, subsection (e) gave the Tax Court jurisdiction to determine relief under subsections (b) and (c) but was silent on (f). In an earlier case, the Tax Court held it could review (f) denials, but only for abuse of discretion, because (f) says the Secretary "may" grant relief. The Court said that was appropriate "[u]nder the statutory framework provided by Congress at the time."
Congress changed the framework in 2006
In 2006 Congress amended § 6015(e)(1) to give the Tax Court jurisdiction "to determine the appropriate relief available" to an individual who requests equitable relief under subsection (f). The Court read the word "determine" as signaling de novo review, as it does elsewhere in the Code, such as the deficiency jurisdiction in § 6213. Nothing in the amended statute suggested deference. When Congress wants abuse of discretion review, it says so, as it did for interest abatement in § 6404. And the Court had always applied de novo review under subsections (b) and (c). "[T]here is no longer any reason to apply a different standard of review under subsection (f) than under subsections (b) and (c), and we shall no longer do so."
Applying the factors
The Court then worked through the factors in the IRS revenue procedure then in effect. Porter and her husband were divorced, which favored relief. Paying would cause economic hardship: she had modest income, two children, and had filed for bankruptcy because of marital debts. That favored relief. She did have reason to know about the item, which weighed against her. But she did not receive a significant benefit beyond normal support, she complied with tax laws in later years, and the Court weighed all the facts and circumstances. On balance, she was entitled to relief from the $1,070.
What Changed After Porter
This is the part most people miss. Porter's companion ruling, earlier in the same case, had also held that the Tax Court conducts a trial de novo and can consider evidence outside the administrative record. In the Taxpayer First Act of 2019, Congress addressed both points. New IRC § 6015(e)(7) provides that any review of a § 6015 determination "shall be reviewed de novo by the Tax Court and shall be based upon (A) the administrative record established at the time of the determination, and (B) any additional newly discovered or previously unavailable evidence." It applies to petitions or requests filed or pending on or after July 1, 2019.
So Porter's core holding, de novo review, is now in the statute. Its broader premise that the Tax Court can hear any evidence at trial has been narrowed. That is why later Tax Court opinions cite Porter as "superseded in part by statute."
What It Means for Taxpayers Today
You get a real second look
If the IRS denies equitable innocent spouse relief, the Tax Court does not defer to that decision. It decides for itself whether it is inequitable to hold you liable. That is a meaningful advantage compared with the abuse of discretion standard that governs most collection decisions.
But the record is mostly made at the IRS
Because § 6015(e)(7) limits the Tax Court to the administrative record plus newly discovered or previously unavailable evidence, your Form 8857 and supporting documents are your trial exhibits. Submit the financial records, the separation and divorce papers, the evidence of who controlled the money, any evidence of abuse, and proof of hardship when you file with the IRS. Do not plan to save your best evidence for court.
Knowledge is not the end of the story
Porter had reason to know about the IRA distribution, and she still won. Under (f), knowledge is one factor. Hardship, divorce, lack of significant benefit and later compliance can outweigh it. Contrast Cheshire v. Commissioner, where knowledge plus significant benefit sank the claim.
The IRS guidance has moved too
The Court in Porter applied the threshold conditions and factors in the IRS revenue procedure in effect at the time. The IRS has since replaced that revenue procedure with updated guidance, and later Tax Court opinions apply the newer factors. In Porter, the Court worked through the revenue procedure's factors while considering all the facts and circumstances, as § 6015(f) directs. When you prepare a request, address each current factor directly, and then tell the rest of the story.
Small dollars, big principle
The tax at stake was $1,070. Porter shows that innocent spouse relief is not only for large liabilities, and that the Tax Court will take a small case seriously when the equities are real. Our overview of innocent spouse relief explains how to start the process.
The Bottom Line
Porter moved equitable innocent spouse relief from deference to decision. Congress agreed and wrote it into the Code, while telling taxpayers to put their evidence in front of the IRS first. Read together, the case and the statute say this: you get a fresh hearing in the Tax Court, but you build the record at the IRS.
