Do You Need Client Consent to Use an Offshore Tax Preparer?

Yes. Under Section 7216, a US tax preparer may share return information with another US preparer helping on the return without consent, but if that preparer is outside the United States, the taxpayer must first sign a consent using the wording in Revenue Procedure 2013-14. Social Security numbers need adequate data protection safeguards at both firms, and each violation risks a $250 civil penalty or criminal penalties.

The rule in plain words

Section 7216 of the Internal Revenue Code controls how tax return preparers use and disclose their clients' tax return information. The IRS's own FAQ sets out the part that matters for outsourcing.

Disclosure to another preparer who is helping prepare the return does not need the taxpayer's consent, as long as that preparer is in the United States or a US territory or possession. If the other preparer is located outside the United States, the taxpayer must agree and sign a consent form before the information is disclosed.

The consent is a formal document, not a line buried in small print.

  • It must use the specific language set out in Revenue Procedure 2013-14, section 5.04(e), for disclosures to preparers outside the US.
  • It must be signed and dated by the taxpayer, in pen and ink or electronically.
  • If it does not state an expiration period, it is effective for one year from the date the taxpayer signed it.
  • Collect it before any information is shared, and keep a copy with the client file.

Social Security numbers

Social Security numbers get stricter treatment. The IRS says preparers may not obtain consents to disclose SSNs to preparers located outside the United States. SSNs can be disclosed only if both the US firm and the offshore preparer maintain adequate data protection safeguards, as defined in section 5.07 of Revenue Procedure 2013-14. In practice, firms either document those safeguards or set up the work so offshore staff never see full SSNs.

Penalties

The IRS FAQ lists both. Under Section 6713, the civil penalty is $250 per violation. Under Section 7216 itself, a knowing or reckless violation is a crime punishable by a fine of up to $1,000, up to one year in prison, or both, for each violation. With a full season of returns, per-violation penalties add up quickly.

How firms handle it in practice

The firms that do this smoothly treat consent as part of onboarding, not a scramble in March.

  • Add the Section 7216 consent to your engagement package for every client whose return may go offshore.
  • Track expiry dates, since a consent without a stated period lapses after a year.
  • Keep the work inside your own systems where you can, so you control access and can remove it.
  • Tell clients in your engagement letter that a third-party provider may help, as the AICPA Code expects, and keep a confidentiality agreement with the provider.
  • Confirm that every person preparing returns for you holds a valid PTIN.

All questions →
Does a CPA firm need client consent to use offshore tax preparers?

Yes. If the preparer receiving the tax return information is outside the United States, the taxpayer must sign a Section 7216 consent, in the wording set by Revenue Procedure 2013-14, before you share it.

Do I need consent to use a US-based preparer?

No. The IRS says disclosure to another US-based preparer who assists in preparing the return does not require the taxpayer's prior consent.

How long does a Section 7216 consent last?

As long as the consent says. If it states no expiration period, it is effective for one year from the date the taxpayer signed it.

Can offshore preparers see Social Security numbers?

Only if both firms maintain adequate data protection safeguards as defined in Revenue Procedure 2013-14, section 5.07. A consent alone is not enough for SSNs.

Do offshore tax preparers working for US firms need a PTIN?

Yes, if they are paid to prepare or help prepare federal returns. The IRS requires a valid PTIN for anyone who does so for compensation; the 2026 fee is $18.75.

Do CPA firms have to tell clients they use an outsourcing provider?

The AICPA Code expects you to tell clients, preferably in writing, before their confidential information goes to a third-party provider. For offshore tax work, Section 7216 also requires their signed consent.
