Business Tax & Entity Structuring Services
Keep your company compliant, tax-efficient & primed for global growth
WHAT WE OFFER
-
Business Tax Returns
We prepare and file federal and state returns for multi-member LLCs, partnerships, S-Corps, and C-Corps—removing the guesswork from compliance. Our team tracks every Tax Filing Deadline US and foreign reporting requirement, from Schedule K-1 allocations to Form 5471 disclosures for owners with overseas subsidiaries. Expect error-free filings, proactive extension planning, and real-time visibility into your tax position through our secure client portal.
-
State Franchise & Excise Tax
From California’s franchise tax to Tennessee’s excise filings, state levies can blindside even seasoned founders. We calculate, file, and pay your assessments on time, ensuring you remain in good standing across all domicile states where you operate—and avoid costly penalties that derail cash flow.
-
LLC Setup & Compliance
Launching the right entity is the first step toward lasting tax efficiency. We advise on U.S. LLC formation for both domestic owners and expats—mapping ownership tiers, drafting operating agreements, and securing EINs. Annual compliance reminders keep you up to date on franchise fees, foreign registrations, and state renewal deadlines.
-
C-Corp Structuring & Optimization
Fast-growing startups often graduate to C-Corps for fundraising and stock option flexibility. We model whether a Foreign Earned Income Exclusion or Foreign Tax Credit could reduce your overall liability, then help you elect or revoke S-status, organize equity classes, and comply with §1202 QSBS requirements.
-
Entrepreneur-Focused Tax Planning
You’re busy building; we’re busy forecasting. Quarterly strategy sessions cover expat taxation scenarios, digital nomad taxes, rental property tax claims, and exit-driven reorganizations. We run projections through our Expatriate Tax Calculator to surface the best blend of deductions, credits, and entity elections—helping you keep more capital in the business.
