When does an accountant malpractice claim accrue during IRS proceedings? Clark v. Deloitte & Touche LLP Explained

In Clark v. Deloitte & Touche LLP, the Utah Supreme Court addressed the critical timing question of when an accountant malpractice claim accrues during ongoing IRS proceedings—a question of first impression for the court.

Background and Facts

The Clarks operated a Farmers Insurance agency and sought tax advice for their 1986 retirement. Their accountants advised them to accept a lump sum payment to claim capital gains treatment before tax law changes in 1987. However, the accountants were unaware of a 1973 Tax Court decision holding that such payments constitute ordinary income. When the IRS audited and assessed additional taxes of $262,298 plus penalties, the accountants continued advising the Clarks to contest the assessment. The Clarks pursued administrative appeals and ultimately Tax Court proceedings, where they received a final judgment in September 1994 for reduced taxes of $129,443 plus penalties.

Key Legal Issues

The central issue was whether the Clarks’ professional malpractice claim accrued when they received the IRS ninety-day letter in 1991 or when the Tax Court entered final judgment in 1994. This timing determined whether their 1998 lawsuit was barred by Utah’s four-year statute of limitations.

Court’s Analysis and Holding

The court applied the principle that limitation periods don’t begin until “the happening of the last event necessary to complete the cause of action” and actual harm manifests. Reviewing decisions from other jurisdictions, the court found the Florida Supreme Court’s reasoning in Peat, Marwick, Mitchell & Co. v. Lane most persuasive. The court emphasized it would be inequitable to require clients to file malpractice claims while simultaneously arguing in Tax Court that their accountant’s advice was correct. The court concluded that because the Clarks reasonably relied on their accountant’s continuing advice to pursue appeals, no actual injury occurred until the Tax Court’s final judgment established their tax liability.

Practice Implications

This decision protects clients who reasonably rely on professional advice during administrative proceedings while preventing indefinite tolling. Practitioners should note that the limitation period will still begin running if clients don’t actually pursue available appeals or if they settle their cases. The court’s analysis also applies to similar professional relationships involving ongoing advice during administrative or judicial proceedings.
