Law Office of Pietro Canestrelli, a Tax Controversy Boutique, APC

The Law Office of Pietro Canestrelli operates as a single-attorney tax controversy practice in Temecula, focused on IRS disputes, state tax audits, and related administrative proceedings rather than general business or transactional law. The scope includes audit defense, appeals, penalty abatement, and representation before the IRS Office of Appeals — the specialized corner of tax practice where clients face active dispute with tax authorities rather than routine filing or planning. The client base consists of individuals and small-business owners caught in audit situations, typically those who've already received a notice and need representation through the agency process. Engagement typically runs on an hourly-fee model for audit defense, since the scope and timeline of agency proceedings isn't always predictable upfront. For a general tax return preparer or a large accounting firm's in-house tax department, this is the outside counsel call when an audit escalates beyond internal handling. For entrepreneurs managing tax compliance proactively or those seeking advance tax planning before a transaction, a broader tax practice or accounting firm is the earlier port of call.
