Strike Tax Advisory

Strike Tax Advisory is a United States specialty tax practice focused on the federal research credit under IRC §41 and coordinating state R&D credits. Public positioning covers discovery interviews, audit-ready documentation, credit calculations, CPA coordination, and ongoing Strike Shield unlimited federal and state audit defense with a published fee-back guarantee on disallowed credits.

The firm markets a contingency commercial model (no upfront retainers; percentage fee when credits are delivered), second-opinion / quality-review work for companies already with a provider, and recovery paths for missed prior-year credits on open returns. Operator-published marketing metrics (client counts, aggregate credits delivered, Inc. 5000 ranking, average credit sizes, and named case-study amounts) should be treated as firm claims, not Index-audited outcomes.

Public contact surfaces list 1-800-916-5165 and a Scottsdale, Arizona mailing address (11445 E Via Linda, ST 2-475). The Index listing also retains Houston as a prior curated geography reference where relevant; confirm current offices and engagement coverage directly with Strike.

Index Verified means Strike Tax Advisory completed Credit Index Trust Gate review against published methodology after a domain-matched operator claim. It is not an IRS endorsement and not tax advice. Confirm engagement terms, fee models, and current credentials directly with Strike before instructing.
