Can an Indian CA Prepare US Tax Workpapers Without a PTIN?

What a PTIN Is and Who Actually Needs One

A PTIN — Preparer Tax Identification Number — is a nine-digit identifier issued by the IRS. Under IRC Section 6109(a)(4) and the regulations at 26 CFR Part 300, any individual who prepares or assists in preparing all or a substantial portion of a US federal tax return for compensation is required to obtain a PTIN and include it on every return they sign.

The operative word is "sign." The PTIN requirement targets the paid preparer who puts their name on the return and takes responsibility for it before the IRS. Supporting staff who work under a signing preparer's supervision — including bookkeepers, data entry personnel, and accounting support staff — are not required to hold a PTIN. Their work feeds into the return; the signing preparer's PTIN goes on it.

An Indian CA firm falls outside the signing preparer category entirely. It prepares workpapers for the CPA's use. The CPA reviews those workpapers, imports them into Drake, UltraTax, Lacerte, or ProSeries, makes any adjustments, signs the return with their own PTIN, and files with the IRS. The Indian firm's name is never on the return. No PTIN required.

The Difference Between a Workpaper Preparer and a Return Preparer

This is the distinction that resolves the PTIN question. Under IRC Section 7701(a)(36), a "tax return preparer" is any person who prepares for compensation all or a substantial portion of a return or claim for refund. The IRS PTIN requirement applies to that person.

An Indian CA firm prepares workpapers. In practice, this means: cleaning and reconciling the client's accounting records, coding transactions in QuickBooks or a similar platform, preparing supporting schedules (depreciation, amortization, vehicle logs), reconciling bank and credit card statements, and producing a trial balance the CPA can use to complete the return. The Indian firm does not enter data directly into the tax software, does not calculate the tax liability, and does not sign or submit anything to the IRS.

Preparing a reconciled trial balance is not "preparing a return." A cleaned QuickBooks file is not a "claim for refund." The IRS treats workpaper preparation as a support function behind the return preparer — not as return preparation itself. The CPA who takes those workpapers and produces the filed document is the preparer. The Indian firm is the bookkeeping support.

Does Treasury Circular 230 Apply to the Indian Firm?

Treasury Circular 230 governs "practice before the IRS." This includes preparing and filing documents with the IRS, representing a taxpayer in conferences, hearings, or IRS proceedings, and providing written tax advice on specific transactions. Enrolled agents, CPAs, and attorneys who practice before the IRS are subject to its conduct standards, competency requirements, and disciplinary provisions.

An Indian CA firm preparing workpapers does none of the above. It does not communicate with the IRS. It does not represent clients. It does not provide tax opinions that go directly to a taxpayer. Its deliverable is a set of workpapers that the CPA reviews before touching the return. Treasury Circular 230 has no jurisdiction over a firm that is not practicing before the IRS — and delivering workpapers to a CPA firm does not constitute practice before the IRS.

What the Indian CA Qualification Actually Covers

A common follow-up from CPAs is whether an Indian CA holds credentials that are relevant to US tax work. The PTIN answer is settled (no PTIN needed for workpaper preparation), but the competence question deserves a direct answer for any CPA evaluating whether to engage an Indian firm.

An ICAI-registered Chartered Accountant completes a minimum three-year articleship — structured practical training under a licensed CA — and passes the CA Final examination, a two-group examination widely regarded as one of the most demanding professional accounting examinations in the world. The pass rate across both groups is consistently below 20 percent. The ICAI is the national regulatory body for CAs in India, equivalent in standing to the AICPA in the United States. The ICAI holds a Mutual Recognition Agreement (MRA) with the ICAEW in the UK, which formally recognizes ICAI membership as peer-level to the ACA qualification.

For US tax workpaper purposes, the relevant skills are accounting, bookkeeping, and financial reconciliation — not US tax law. The Indian CA handles those functions. The CPA with US tax expertise handles the return. This mirrors how US CPA firms use domestic paraprofessionals: the paraprofessional prepares, the CPA reviews and signs.

What the Indian CA Firm Needs Before Starting

The Indian firm does not need a PTIN. What it does need — and what any responsible CPA should require before sharing client files — is the following:

• Signed Non-Disclosure Agreement (NDA): Confirms that all client information is confidential, cannot be disclosed to any third party, and must be returned or destroyed at engagement end. Protects you from downstream leakage.
• Signed Data Processing Agreement (DPA): Specifies how client data is stored (encrypted at rest, secure cloud portal), who within the Indian firm can access it, how files are transferred (secure portal, never plain email), retention period, and the deletion procedure. Satisfies the confidentiality obligations under the AICPA Code of Professional Conduct Rule 1.700.001.

From the client's side, you need a signed IRC Section 7216 consent form before sharing any tax return information with the Indian firm. This is the client's written authorization for you to disclose their tax data to a named third party. It must identify the Indian firm by name, describe the information being shared, state the purpose, and cover the relevant tax year(s). Without it, sharing the data violates federal law regardless of what the Indian firm does or does not hold.

Sharma Jyoti and Co provides a standard NDA and DPA as part of onboarding. Both documents are drafted with US CPA firm requirements in mind. We can also provide sample IRC 7216 consent language for your engagement letter on request.

What This Means for Your Practice This Tax Season

For a CPA evaluating Indian CA support ahead of the next filing season, the PTIN question is not the blocker. It has a clean answer. The right questions are operational: Is the Indian firm ICAI-registered? Do they have an NDA and DPA ready to sign? Do they have experience preparing the specific return types you handle — 1040s, 1120-S, 1065s, Schedule C? Do they use a secure file transfer portal?

No IRS registration, no PTIN, no Circular 230 enrolment is required on the Indian side. The CPA covers all of that. The Indian firm covers the bookkeeping and workpaper preparation. A solo CPA processing 150 returns per season can realistically offload 60–70 percent of the reconciliation and catch-up work to an Indian CA team at $6–$15 per hour, compared to $35–$65 per hour for a US bookkeeper. For a practice running at capacity from January through April, that difference is not marginal — it is the difference between hitting every deadline and missing them.

The legal framework is clear. The division of work is established. The only thing left is making the first call.
