The Big Accounting firms in the US dispense CPA and some legal advice on taxes.  How to parse one from the other is discussed in Boesky v Levine  2021 NY Slip Op 02059 [193 AD3d 403] April 1, 2021 Appellate Division, First Department.

“The motion court properly dismissed as time barred the legal malpractice claims that pertain to legal services received from Levine and Herrick Feinstein from 2002-2005. The complaint does not allege that at the time defendant Levine provided legal services to plaintiffs regarding structuring and investing in the tax shelters from 2002-2005, the parties contemplated future services in connection therewith. Nor does the complaint contain allegations that there was continuous representation from 2002 forward regarding the structuring of the tax shelters (Johnson v Proskauer Rose LLP, 129 AD3d 59, 67-68 [1st Dept 2015]). However, the complaint sufficiently alleges that Levine subsequently represented plaintiffs in connection with audits by the Internal Revenue Service (IRS) and New York Department of Taxation and Finance (NYDTF) and in tax litigation continuously from May 16, 2008, the date Boesky signed a power of attorney permitting Levine to represent him before the NYDTF, through 2016. Whether the advice Levine allegedly dispensed with regard to the audits and litigation was provided solely in his capacity as tax matters partner for one of the limited liability companies in which plaintiffs invested, and not as their attorney, is an issue of fact that cannot be resolved on the pleadings.

The claim should also be reinstated against Herrick Feinstein (see Waggoner v Caruso, 68 AD3d 1, 6-7 [1st Dept 2009] [finding that sound policy considerations support the tolling of the statute of limitations under the continuous representation doctrine while the representation of the same matter in which the malpractice is alleged is ongoing], affd 14 NY3d 874 [2010]). This Court, in HNH Intl., Ltd. v Pryor Cashman Sherman & Flynn LLP (63 AD3d 534, 535 [2009]), held that the statute of limitations was tolled as to a malpractice claim against a law firm because the attorney(s) who handled the case continued to represent the plaintiffs in the same matter, albeit while at different law firms. Additionally, the claim should be reinstated against Moritt Hock for the period from September 2012 through 2016, when Levine was a partner at the firm and was [*2]allegedly still representing plaintiffs in connection with the audits and tax litigation. The complaint sufficiently alleges that Levine, while at Moritt, continued to advise plaintiffs regarding the tax litigation and sufficiently alleges that but for Levine’s continued failure to properly advise them of the weaknesses of their case, they would have settled with the IRS to reduce their financial exposure and litigation costs.”
