A widower’s estate lost about $3.7 million of federal exemption last summer because his late wife’s Form 706 listed her property and left every value blank. That is Estate of Rowland v. Commissioner, T.C. Memo. 2025-76 (July 15, 2025): a return filed for no reason except portability is still held to the completeness standard in Treas. Reg. § 20.2010-2(a)(7).
In California that runs into a common assumption. The state has no estate tax, and community property gets a full basis step-up at the first death under 26 U.S.C. § 1014(b)(6), the survivor’s own half included. Both true, and neither touches the exemption the survivor will need later.
Short answer: if a couple’s community estate approaches half the federal basic exclusion amount, $15,000,000 for deaths in 2026, file at the first death, and prepare the return as though the IRS will read every schedule.
What did the Tax Court actually hold in Estate of Rowland?
Fay Rowland died in April 2016, her husband Billy in January 2018. No return was required, but her executor filed one to elect portability, six months late, though inside the two-year window then allowed by Rev. Proc. 2017-34. The return listed real property, closely held stock, and bank accounts, entered “$0” for each category, reported $3 million as the estimated value of assets subject to the special rule, and claimed a DSUE amount of $3,712,562.
Her trust gave twenty percent to a family charitable foundation, gave Billy one-fourth of her gross estate, and poured the residue into trusts for grandchildren. Treas. Reg. § 20.2010-2(a)(7)(ii) lets an executor describe rather than value marital and charitable deduction property, but not where that value “relates to, affects, or is needed to determine, the value passing from the decedent to a recipient other than the recipient of the marital or charitable deduction property.”
The grandchildren took the residue, so those figures controlled. Chief Judge Urda granted partial summary judgment to the Commissioner and turned away both substantial compliance and equitable estoppel.
Doesn’t California community property already take care of this?
It takes care of a different tax. Section 1014(b)(6) gives a new basis to the surviving spouse’s half of the community, not just the decedent’s, so long as at least half the community interest was includible in the decedent’s gross estate. That is an income tax rule about a later sale. Portability is a transfer tax rule, and 26 U.S.C. § 2010(c)(5)(A) gives the survivor none of the DSUE amount defined in § 2010(c)(4) unless the executor “files an estate tax return on which such amount is computed and makes an election on such return.”
No state tax makes this worse. California’s estate tax at Rev. & Tax. Code § 13302 is a pick-up tax pegged to the federal credit for state death taxes, gone since January 1, 2005, and the State Controller says no California estate tax return has been required since. A gross estate under the exclusion means no federal return is required under § 6018(a). Not required and not worth filing are different things.
How long does a California surviving spouse have to fix a missed election?
Nine months from death, plus six more if a Form 4768 goes in on time. The automatic extension comes from Treas. Reg. § 20.6081-1(b) under 26 U.S.C. § 6081, and Treas. Reg. § 20.2010-2(a)(1) ties the election to that date.
After that, Rev. Proc. 2022-32 is the rescue. Effective July 8, 2022, it lets an executor file by the fifth anniversary of death if the decedent was a citizen or resident who died after December 31, 2010 survived by a spouse, the estate was not required to file under § 6018(a), and no timely return went in. The return must carry a statement at the top: “FILED PURSUANT TO REV. PROC. 2022-32 TO ELECT PORTABILITY UNDER § 2010(c)(5)(A).”
If the gross estate plus adjusted taxable gifts turns out to have exceeded the exclusion, the relief is null and void ab initio, leaving only a § 9100 letter ruling. Section 4.01 also demands a “complete and properly prepared Form 706” under Treas. Reg. § 20.2010-2(a)(7), the sentence the court applied in Rowland. A late return that is still wrong buys nothing.
Did your spouse die in the last five years with no Form 706 filed? The Rev. Proc. 2022-32 window is probably still open, it closes for good on the fifth anniversary, and having an attorney and CPA look at the trust and the asset values together now costs far less than a letter ruling later.
What goes on a portability-only Form 706 when the estate is community property?
Only the decedent’s half. Cal. Fam. Code § 760 makes property acquired during marriage while domiciled here community property, and Cal. Prob. Code § 100(a) provides that on death “one-half of the community property belongs to the surviving spouse and the other one-half belongs to the decedent.” The survivor’s half stays outside the gross estate and still takes a new basis, so the return still has to show the property was community.
The estimate rule can apply here, and often does when everything pours into a survivor’s trust. Subparagraph (a)(7)(ii) lets the executor describe marital and charitable property without valuing it, so long as the executor uses due diligence to estimate the gross estate and reports the matching range from the Instructions for Form 706 under penalties of perjury.
The exceptions catch California trusts. The rule is off the table when a value affects what a non-spouse, non-charitable beneficiary receives, when it is needed for § 2032 or § 2032A or another estate or generation-skipping provision, when only a partial interest qualifies, or on a partial disclaimer or QTIP election. A formula bypass share, a disclaimer trust, a QTIP marital trust, or a carve-out for children of a prior marriage lands on the Rowland side of that line.
What does “complete” mean for a house and a closely held business?
Date-of-death fair market value, asset by asset, on the right schedule. The home goes on Schedule A with a real appraisal. S corporation stock goes on Schedule B with an actual valuation and discounts that are supported, not asserted. Where a value is genuinely hard to pin down, the answer is a defensible estimate with the methodology in the file, not a blank.
The return does two jobs: it elects portability, and it is the contemporaneous record behind the stepped-up basis the survivor claims on a later sale. There is a fiduciary dimension too: a trustee who lets the nine months lapse, or signs a return with zeros in the value column, hands the surviving spouse a claim to weigh against the preparer or the fiduciary.
What does this look like for a Redlands couple with a $9 million community estate?
Assume a Redlands couple, all community property: a home in the historic district at $1.4 million, a Riverside fourplex at $1.6 million, stock in their HVAC S corporation at $4.5 million, and $1.5 million in retirement, brokerage, and cash. He dies in March 2026 and it all stays in trust for her. The figures are illustrative; future indexing is unknown, so the example freezes the exclusion at 2026.
His gross estate is his half, $4.5 million, and the marital deduction takes his taxable estate to zero, so the DSUE is the full $15,000,000 and her applicable exclusion becomes $30,000,000. Separately, all $9 million takes a new basis under section 1014(b)(6).
Say she dies in 2036 and assets grew 7 percent a year, taking $9 million to roughly $17.7 million. With no return ever filed, her exclusion is $15 million, her taxable estate about $2.7 million, and the tax at the 40 percent top rate under 26 U.S.C. § 2001(c) runs about $1,080,000. A return filed but defective the way Fay Rowland’s was produces the identical number, found long after the Rev. Proc. 2022-32 window closed. With a complete return, the tax is zero.
Does remarriage change the DSUE amount?
Not by itself. Treas. Reg. § 20.2010-3 makes the available DSUE that of the surviving spouse’s last deceased spouse, and a decedent keeps that status “even if, on the date of the death of the surviving spouse, the surviving spouse is married to another (then-living) individual.” A Temecula widow who remarries in 2029 still has her first husband’s DSUE.
The new spouse dying first is what changes it. If his executor makes no election, the earlier DSUE is gone except to the extent it “was applied to one or more taxable gifts of the surviving spouse.” Where remarriage is likely, spend the DSUE on lifetime gifts. Divorce is not the danger: the later death of a divorced spouse does not end the prior spouse’s status.
| Path at the first death | What must be reported | Deadline | Risk under Rowland |
|---|---|---|---|
| No Form 706 filed | Nothing | None | DSUE is permanently $0, and no contemporaneous basis record exists |
| Portability-only 706, estimate rule available (all to spouse and/or charity) | Describe marital and charitable property; value everything else; report a best-estimate range for the gross estate | 9 months, plus 6 months on Form 4768; otherwise 5 years under Rev. Proc. 2022-32 | Estimate rule collapses if any value affects a non-spouse, non-charity share |
| Portability-only 706, estimate rule unavailable (bypass share, children, QTIP, partial disclaimer) | Date-of-death fair market value of every asset, schedule by schedule | Same | This is Rowland: blank or $0 values void the election entirely |
| Full 706 required under § 6018(a) | Full valuation, all schedules, tax computed | 9 months plus 6-month extension only | Rev. Proc. 2022-32 relief is void ab initio; only remedy is a § 9100 letter ruling |
Frequently Asked Questions
Do I have to file a Form 706 in California if there is no California estate tax?
Nothing at the state level: California has required no estate tax return for deaths on or after January 1, 2005. Federally, no return is required if the gross estate is under the basic exclusion amount, $15,000,000 for deaths in 2026. Filing anyway is the only way to capture the unused exclusion.
Does California’s community property step-up make portability unnecessary?
No. Section 1014(b)(6) gives both halves of community property a new income tax basis at the first death, which reduces capital gain on a later sale. Portability under section 2010(c) concerns the federal estate tax exemption at the second death. Only the basis adjustment happens without paperwork.
What did the Tax Court decide in Estate of Rowland?
In Estate of Rowland v. Commissioner, T.C. Memo. 2025-76 (July 15, 2025), the court held that a return filed purely to preserve a spouse’s exemption still must meet the completeness standard of Treasury Regulation section 20.2010-2(a)(7). It listed assets but reported zero values, and percentage gifts to a spouse, a foundation, and grandchildren put the reduced reporting rule out of reach, so about $3.7 million of exclusion was lost.
How long do I have if we missed the portability deadline?
Revenue Procedure 2022-32 allows an executor to file a complete and properly prepared Form 706 by the fifth anniversary of the decedent’s death, provided the estate was not required to file under section 6018(a) and no timely return went in. The return must say at the top that it is filed pursuant to that procedure. After that, the only route is a private letter ruling.
Does remarriage affect the DSUE?
Remarrying does not by itself cost the surviving spouse anything, because under Treasury Regulation section 20.2010-3 a decedent stays the last deceased spouse even if the survivor is married to someone else at death. The risk is the new spouse dying first, which wipes out the earlier DSUE except to the extent already applied to taxable gifts.
What if the estate has assets that are hard to value, like a closely held business?
Hard to value does not mean exempt from valuation. The executor must exercise due diligence and report a supportable date-of-death figure, or, where the reduced reporting rule applies, a good-faith estimate within the range in the Instructions for Form 706. An appraisal and a business valuation protect both the election and the later basis claim.
