OPINION

Presiding Judge Michael S. Catlett delivered the opinion of the Court, in which Judge Daniel J. Kiley and Judge James B. Morse Jr. joined.

C A T L E T T, Judge:

¶1 Legal malpractice claims must commence “within two years after” they “accrue.” A.R.S. § 12-542. But our legislature has not defined when such claims accrue. Glaze v. Larsen, 207 Ariz. 26, 29 ¶ 9 (2004). Instead, that has been “left to judicial decision.” Id. In a non-litigation context, legal malpractice claims accrue when the client should know its attorney’s negligence caused the client harm. Com. Union Ins. v. Lewis and Roca, 183 Ariz. 250, 252–53 (App. 1995). And harm is sufficient when “irremediable or irrevocable[.]” Keonjian v. Olcott, 216 Ariz. 563, 566 ¶ 13 (App. 2007). We decide whether the plaintiffs timely asserted their legal malpractice claim based on negligent tax advice.

FACTS AND PROCEDURAL HISTORY

¶2 In July 2006, DMB Realco, LLC (“DMB”) retained an attorney at Mariscal, Weeks, McIntyre, & Friedlander, P.A. (collectively, “Mariscal”) to donate a conservation easement to the Town of Buckeye (“Buckeye”). Mariscal prepared a conservation easement deed (“Original Deed”), intending for it to qualify DMB for a charitable contribution under Section 170 of the Internal Revenue Code (“Code”). DMB recorded the Original Deed in December 2006. So on its 2006 tax returns, DMB claimed a $26.44 million deduction (“Deduction”).

¶3 Fast forward four years. The Internal Revenue Service audited DMB’s 2006 tax return. The IRS objected to the Deduction because it thought the Original Deed violated Treasury Regulations and the Code. DMB retained tax counsel.

¶4 In May 2011, an IRS Agent (“the Agent”) sent DMB a Form 4605-A Examination Changes Report (“Preliminary Report”), outlining why the Deduction failed. The Preliminary Report included a Draft Non Cash - Land Conservation Easement Lead Sheet (“the Draft Lead Sheet”), explaining DMB “failed to obtain a qualified appraisal, failed to obtain a

contemporaneous written acknowledgement, and did not fully complete the [appraisal summary].” The Draft Lead Sheet concluded “[t]he easement [was] not granted in perpetuity, and the vested rights of the donee organization do not meet the requirements of the regulations.” After DMB’s tax counsel responded, the Agent revised the Draft Lead Sheet, sending a final version (“2011 Lead Sheet”) in July 2011.

¶5 In January 2012, the IRS sent DMB a 60-Day Letter (“First 60- Day Letter”), explaining it was “proposing adjustments to partnership items for the” 2006 tax year. That Letter gave DMB three options: (1) agree to the adjustments by paying additional taxes, interest, and penalties; (2) request an appeals conference; or (3) do nothing.

¶6 DMB chose option two—it appealed. In April 2012, DMB “dispute[d] all of the[] proposed adjustments.” DMB admitted Mariscal erred in “paragraph 6 of the [Original] Deed,” but it maintained the Original Deed complied with Treasury Regulations and reforming the Deed would fix non-compliance. Soon after, DMB recorded an amended and restated deed (“Amended Deed”).

¶7 In September 2012, DMB supplemented its protest, notifying the IRS that the Amended Deed “clarif[ied] the parties’ original intent[.]” That supplement also discussed more caselaw and provided a new appraisal, while still challenging the proposed adjustments. So the IRS returned the case to the Agent.

¶8 In May 2014, the Agent sent DMB a Form 4605-A Examination Changes Report, addressing DMB’s protest. The Agent conceded “[t]he issues regarding qualified appraisal and appraisal summary” but still challenged the “contemporaneous written acknowledgement, qualified real property interest granted in perpetuity, and valuation” issues. After revisions, the Agent issued a final report (“2014 Report”), again canceling the Deduction.

¶9 In October 2014, the IRS issued a new 60-Day Letter (“Second 60-Day Letter”), explaining it was “proposing adjustments to partnership items for the partnership and [2006 tax year].” That Second 60-Day Letter again gave DMB three options; DMB again appealed. In that appeal, DMB “dispute[d] all of the[] proposed adjustments.” DMB’s tax counsel then spent a year negotiating with IRS staff.

¶10 In December 2015, the IRS Office of Appeals issued a Final Partnership Administrative Adjustment (“FPAA”), adjusting “certain

partnership items” for 2006. The FPAA explained the Deduction violated Section 170, so the IRS canceled it.

¶11 In 2016, DMB sued in state court to reform the Original Deed and in federal court to challenge the FPAA. In state court, DMB got a judgment reforming the Original Deed retroactive to “the original recording date,” thereby mirroring the Amended Deed’s terms. In federal court, DMB settled with the United States. The United States agreed DMB could deduct $6,610,000 for 2006, if it paid penalties and interest.

¶12 In July 2016, DMB and Mariscal paused the statute of limitations using a tolling agreement. After extensions, that agreement expired in June 2018.

¶13 In August 2018, DMB sued Mariscal. Mariscal moved for summary judgment, relying on the statute of limitations. See A.R.S 12-542. Mariscal argued DMB’s malpractice claim accrued in July 2011, when DMB received the 2011 Lead Sheet. Mariscal argued DMB’s harm then became “irremedia[ble]” and “irrevocable” because the Agent claimed errors in the Original Deed could not be fixed. DMB responded that accrual occurred no earlier than December 2015, when the IRS issued an FPAA.

¶14 The superior court granted summary judgment. It concluded Mariscal harmed DMB when DMB executed the Original Deed. The court also concluded DMB discovered its harm no later than April 2012, when it filed its protest. So by waiting four years to pause the limitations period— two years after accrual—DMB’s claim came too late.

¶15 Three months after final judgment, Mariscal sought sanctions because DMB had rejected an offer of judgment. The court said no.

¶16 DMB appealed summary judgment and Mariscal cross- appealed sanctions. We have jurisdiction. See A.R.S. § 12-2101(A)(1).

DISCUSSION

¶17 DMB challenges summary judgment. We review summary judgment de novo, viewing the facts most favorably to DMB (the non- moving party). See Andrews v. Blake, 205 Ariz. 236, 240 ¶ 12 (2003). Summary judgment lies when “there is no genuine dispute as to any material fact and [Mariscal] is entitled to judgment as a matter of law.” Ariz. R. Civ. P. 56(a); Orme Sch. v. Reeves, 166 Ariz. 301, 309 (1990). A “court may determine” accrual “as a matter of law.” Satamian v. Great Divide Ins., 257 Ariz. 163, 170 ¶ 14 (2024).
