Tax Return Preparation Services for US CPA Firms
Offshore Tax Preparation — Accurate, Deadline-Driven, and Fully Review-Ready
Tax season puts immense pressure on CPA firms — more returns to prepare, tighter deadlines, and the constant challenge of finding skilled preparers. Athix Global provides offshore tax return preparation support exclusively for US CPA firms, working as a silent extension of your team during your busiest months — and year-round.
Our tax preparers are experienced in federal and state compliance across all major return types. We work in your software, follow your preparation standards, and return clean, review-ready drafts — so your CPAs spend time reviewing and advising, not preparing from scratch.
Return Types We Prepare
- Individual Tax Returns — Form 1040
- Partnership / LLP / LLC Returns — Form 1065
- C-Corporation Returns — Form 1120
- S-Corporation Returns — Form 1120-S
- Trust & Exempt Organization Returns — Form 990
How It Works
- 1. You send source documents and prior-year returns via your secure portal or shared platform.
- 2. Our preparers prepare the return in your tax software — Drake, UltraTax, ProConnect, CCH, or others.
- 3. We return a completed draft with open items, review notes, and a preparation summary.
- 4. You review, finalize, and file — your firm’s name, your signature, your client relationship.
