Tax Service
Whether you’re a C-Corp, S-Corp, Partnership, Foundation, or managing multi-entity projects or DAOs, our Tax Services cover the full spectrum—from federal and state returns to international disclosures and FBAR/FATCA filings. We optimize every credit, deduction, and election (including QSBS and R&D credits) to minimize your total tax bill, then handle all the paperwork, filings, and IRS/state communications on your behalf. With transparent, fixed-fee pricing, you can budget with confidence and never worry about surprise invoices.
We also conduct mid-year tax health checks to catch issues before they become costly—reviewing estimated payments, extensions, and treaty benefits for cross-border operations. And if you need to pivot—say, to spin out a token-issuer subsidiary, establish a foundation, or reorganize as an S-Corp—we’ll guide you through the structural changes and their tax impacts to ensure a smooth transition.
