Your tax return contains your Social Security number, your income, your bank accounts, your children's names, and your business's financials. A growing number of U.S. tax firms send that file overseas for preparation. It's legal — with your consent. The uncomfortable part is how many taxpayers give that consent without ever realizing they did.
Offshore tax preparation is now routine in the industry. Facing staffing shortages and margin pressure, a significant number of U.S. firms — including some large, familiar names — route return preparation to processing centers abroad. The U.S. firm signs the return and manages the client relationship; the data entry, and sometimes substantially more, happens somewhere else.
The IRS has permitted this since 2006. It is not fraud, it is not a scandal, and plenty of offshore providers do competent work under real security protocols. But it operates on one condition — your informed, written consent — and that condition is where the story gets interesting for Frederick County taxpayers.
Internal Revenue Code Section 7216 governs what a tax preparer may do with your information. The default is strict: a preparer may not disclose your tax return information to anyone else without your consent. Violating it is a criminal misdemeanor — up to a year in prison and a fine — with a civil counterpart under Section 6713 adding penalties per disclosure.
Sending your file offshore is a disclosure. So the firm must obtain your written consent first, and the regulations are unusually specific about what that consent has to look like:
| Requirement | What It Means for You |
|---|---|
| Standalone document | The consent cannot be buried in the fine print of an engagement letter — it must be its own document you sign |
| Signed before disclosure | No retroactive consent. If your data already went overseas, a signature afterward doesn't fix it |
| Cannot be a condition of service | A firm may not require you to consent in order to be a client. If it does, the consent is invalid |
| Names the recipient and purpose | You're entitled to know who is receiving your information and why |
| Special SSN language | If your Social Security number is disclosed, the form must say so explicitly and disclose the safeguards in place |
| The enforcement warning | The form must tell you that U.S. agencies may not be able to enforce American privacy protections against a preparer located abroad |
| Revocable, and time-limited | You can withdraw consent at any time; absent a stated duration, it expires after one year |
Read that second-to-last row again. Federal law requires the consent form to warn you that if something goes wrong with your data overseas, U.S. authorities may be unable to enforce American privacy law against the party that has it. That sentence exists because the risk it describes is real — and it is sitting in a document that a great many taxpayers sign in a stack at the front desk without reading.
Maybe you did. The consent is a real form with real disclosures — but it's often presented in a pile of onboarding paperwork during the busiest month of the year, next to the engagement letter and the e-file authorization, and most people sign the stack.
Three things worth knowing:
You don't need to be alarmed. You do need to ask. One direct question to any preparer, chain, or firm you're considering:
"Is any part of my return prepared, reviewed, or accessed outside the United States — and if so, by whom?" A firm with nothing to hide will answer immediately and plainly. Hesitation, deflection, or a vague answer about "our global team" is itself the answer. You are entitled to know where your Social Security number is going, and no reputable firm will resent you for asking.
Then read what you sign. If you're handed a separate consent form mentioning disclosure outside the United States, that's what it is — and you may decline it. A firm cannot refuse to serve you for saying no (though it may charge more to keep the work in-house, which is an honest tradeoff to be offered).
There's a quality dimension too, and it connects to the reason people hire professionals in the first place.
A preparer working from a checklist thousands of miles away is entering data. They are not going to notice that your Maryland return needs a bonus depreciation addback your federal return doesn't. They're not going to flag that your 1099 income has crossed the threshold where an S-Corp election would save you thousands, or that your Frederick County local rate was applied incorrectly, or that a rental loss is suspended when it needn't be. Those catches come from someone who knows Maryland, knows your history, and is actually thinking about your situation rather than processing a file.
That's the same argument we make in our comparison of CPAs, tax chains, and software — the value isn't in the typing. It's in the judgment.

Book a ConsultationAsk them directly, and check your paperwork from prior years for a standalone consent form mentioning disclosure outside the United States. If such a form exists in your file, your data has likely gone abroad. If a firm can't or won't give you a clear answer, treat that as informative.
No — it's legal with proper, informed, written consent that meets the Section 7216 requirements. The problems arise when consent is defective (buried in an engagement letter), coerced (made a condition of service), or obtained after the fact. Legal isn't the same as disclosed, and disclosed isn't the same as understood.
Yes. Conditioning tax preparation services on your consent makes that consent invalid under the regulations — a firm cannot lawfully make it a requirement. It may offer to keep the work in-house at a higher fee, which is a fair choice to be given. You can also revoke consent you've already provided, at any time.
No. Your return is prepared and reviewed in our Frederick office by a licensed CPA. Nothing goes offshore, and no part of your file is sent to an outside processing center. If that matters to you — and for many of our clients, it's exactly why they came to us — you'll never have to wonder.
