Tax Preparation Support
Offshore tax preparation support for CPA firms
We prepare the returns and the workpapers. Your firm reviews, signs, and files. You get busy-season capacity without professional responsibility ever leaving your desk.
Busy season doesn't scale. Your team does, until it can't.
Every firm hits the same wall between January and April. Returns pile up, review slows, and the only levers are overtime or turning work away. Hiring seasonal staff who are productive by day one is close to impossible.
We give you a prepared, review-ready return instead of a blank one. Your reviewers spend their time reviewing, not preparing from scratch, and your firm takes on the season's volume without burning out.
What we handle
- Individual returns (Form 1040) preparation
- Business returns (Forms 1120, 1120-S, and 1065) preparation
- Review-ready workpapers and tax-ready financials
- Book-to-tax adjustments and reconciliations
- Depreciation and fixed-asset schedules
- Prior-year comparisons and preparer review notes
- Extension preparation
- E-file-ready packages assembled for your review
- Canadian T1 and T2 preparation
Prepared to be reviewed, not redone
A prepared return only helps if your reviewer trusts it. We prepare to your firm's checklist, attach clear workpapers and comparison notes, and flag anything that needs a second look. The goal is simple: your reviewer opens the file and moves through it, instead of rebuilding it.
How we work with your data (IRC §7216)
We prepare and support; your firm reviews, signs, and files, and remains the taxpayer's preparer of record. Under IRC §7216, your firm obtains the taxpayer's prior written consent before tax return information is shared with a preparer outside the United States. We work only with data you're authorized to share, use it solely for the work you assign, and protect it under our full security controls. See our Security page for details.

Common questions
Do you file returns?
No. We prepare returns and workpapers for your firm to review, sign, and file. You keep professional responsibility and the client relationship.
Which software do you prepare in?
Drake, UltraTax, ProConnect, and CCH. If your firm uses another, tell us on the fit call.
How do you handle §7216 and taxpayer data?
Your firm obtains the required consent and stays the preparer of record. We work only with authorized data, use it solely for your assigned work, and protect it under strict controls.
Can you handle busy-season volume?
Yes. Capacity scales up for the season and back down after, which is exactly what dedicated and overflow models are built for.
