PTIN for Offshore Tax Preparers: How CPA Firms Onboard a Dedicated Preparer in 2026

A PTIN for offshore tax preparers is required whenever the preparer is paid to prepare, or help prepare, all or substantially all of a US federal return, even if a US partner reviews and signs it. A foreign preparer without a Social Security number applies online and uploads notarized identity documents, and the IRS allows six weeks for that review, so the application belongs at the very start of onboarding.

The PTIN is only the first item. Before a dedicated offshore preparer opens a client file, the firm also needs signed Section 7216 consents, controlled access to its tax software, a written review workflow and training on the 2026 law changes. This guide walks through each step in the order most CPA firms complete them, with dates set against the January to April 2027 filing season.

If your firm is still deciding whether a dedicated person or a per-return arrangement fits, start with our comparison of dedicated staff vs per-return pricing. This page assumes that decision is made and the preparer is joining your team.

Who Counts as a Tax Return Preparer for PTIN Purposes

The IRS PTIN rules turn on the work a person does, regardless of job title or location. Its FAQ states that a PTIN "must be obtained by all enrolled agents, as well as all tax return preparers who are compensated for preparing, or assisting in the preparation of, all or substantially all of any U.S. federal tax return, claim for refund, or other tax form submitted to the IRS," with a short list of exempt forms (IRS PTIN FAQ).

Two points from that FAQ matter most for an offshore role:

• Non-signing preparers still need one. The IRS notes that non-signing preparers are left off the return, and adds that "they still are required to have a PTIN."
• Pure data entry does not trigger the requirement. In the IRS scenarios, an administrative assistant who records client data while the PTIN holder advises and signs "is not a tax return preparer, and is not required to have a PTIN."

A dedicated offshore preparer who builds the 1040, enters K-1s, works the depreciation schedule and flags diagnostics is doing preparation work. The firm should treat a PTIN as a condition of the role. A PTIN also cannot be shared, so each person on a dedicated offshore team needs their own.

Step 1: PTIN for Offshore Tax Preparers Without an SSN

Most offshore preparers are neither US citizens nor resident aliens and cannot get a Social Security number. The IRS FAQ covers this case directly: such a preparer "can register for a PTIN online. Notarized copies of your identification documents must be submitted," uploaded through the online PTIN account. The preparer provides two notarized documents from the IRS list, and the agency says to "Allow 6 weeks for the IRS to review." Once the documents are approved, the preparer finishes the online application.

The older paper route through Form 8946 appears on an IRS page now marked historical, so plan around the online process.

Timing matters here. The IRS PTIN page says anyone who prepares or assists in preparing federal returns for compensation "must have a valid 2027 PTIN" before preparing returns, and lists the fee for renewals and first-time applications as $18.75 (IRS PTIN requirements). As of October 2026, 2027 applications and renewals are already being processed. A preparer who starts the identity review in early November has a realistic chance of holding a valid PTIN before January work begins. A preparer who starts the review in January may not be cleared to work until late February.

Step 2: Section 7216 Consent Before Any Client Data Moves

Under the Section 7216 regulations, a US preparer can share return information with its own US staff without client consent. That exception stops at the border. The regulation says that if the person receiving the information "is located outside of the United States or any territory or possession of the United States, the taxpayer's consent under § 301.7216-3 prior to any disclosure is required" (26 CFR 301.7216-2 via Cornell LII). This applies even when the offshore preparer works for the same firm.

For Form 1040 clients, Rev. Proc. 2013-14 sets out the consent format and the statements that must appear in it (Rev. Proc. 2013-14). Two versions apply:

• SSN masked or excluded. The consent must include the statement: "This consent to disclose may result in your tax return information being disclosed to a tax return preparer located outside the United States."
• SSN visible to the offshore preparer. The consent needs a longer statement, and the disclosure is allowed "only when both the tax return preparer located within the United States and the tax return preparer located outside of the United States maintain an adequate data protection safeguard" when consent is obtained and when the disclosure is made.

In practice, send consents with the engagement letter in December, track signatures in your practice management system, and hold back any file without a signed consent. Our guide to Section 7216 consent covers wording and timing in more depth.

Step 3: Software Access and Data Handling

The dedicated preparer should work inside your environment, under a named login, with access limited to the clients assigned to them. Most firms use a virtual desktop or hosted tax software so client files never sit on a local machine. The detailed setup, including user roles and multi-factor authentication, is covered in our tax software access checklist for offshore preparers.

A few onboarding decisions belong here:

• Give the preparer a firm email address and route all client communication through your staff, so the client relationship stays with the firm.
• Decide whether SSNs will be masked, since that choice determines which Section 7216 statement your consents need.
• Keep e-file submission and signature authority with US staff who hold signing responsibility.
• Remove access the day the engagement ends or the person changes roles.

Step 4: A Written Review Workflow

Many offshore arrangements break down at review, where notes come back slowly and the same errors repeat. A dedicated preparer fixes the continuity problem only if the firm writes the workflow down.

Start with your real checklist. Share the actual preparation checklist, naming conventions, workpaper index and open-item format your seniors use. Assign one firm contact who answers questions and gives feedback on each batch of work. Without a single owner, questions sit in several inboxes.

Then set review levels. During the first weeks, a senior reviews every return in full and writes specific notes. Track repeat issues in a shared log. Once error rates fall, move simple returns to a lighter review while complex returns keep a full one. Final judgment on tax positions and client advice stays with the firm, along with the decision to file. Our piece on outsourced tax reviewers vs tax preparers explains which tasks to delegate first.

A typical onboarding calendar for a preparer starting before the 2027 season looks like this:

Step 5: Training on the 2026 Law Changes

The One Big Beautiful Bill Act (Public Law 119-21) changed several items a preparer will see on tax year 2026 returns filed in 2027. The IRS summary lists new deductions effective for 2025 through 2028 (IRS OBBB deductions page):

• Qualified tips: maximum annual deduction of $25,000, phasing out above $150,000 of modified AGI ($300,000 joint).
• Qualified overtime: deduction for the pay above the regular rate, such as the "half" portion of time-and-a-half, capped at $12,500 ($25,000 joint), with the same phase-out thresholds.
• Car loan interest: up to $10,000 on a qualifying new vehicle bought for personal use, phasing out above $100,000 ($200,000 joint). Lease payments do not qualify.
• Seniors: an extra $6,000 per eligible person age 65 or older, phasing out above $75,000 ($150,000 joint).

The 2026 standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household (IRS 2026 inflation adjustments).

A good training test is the overtime deduction, because new preparers often deduct the full overtime pay. Take a single filer with a $30 regular hourly rate who worked 200 overtime hours at time-and-a-half, with modified AGI well under $150,000:

The deduction is $3,000. A preparer who enters $9,000 has overstated it by $6,000. Build a handful of test returns like this into week one, along with your firm's own state conformity notes. For a broader training plan, see how to train an offshore team on US GAAP and the US tax code.

Managing a Dedicated Offshore Preparer After the First Season

Once the preparer has a season behind them, the arrangement starts to pay off. They know your clients and the way your reviewers write notes. Keep the error log running and renew the PTIN each fall. Refresh training whenever Congress or the IRS changes a rule your clients use.

Frequently Asked Questions

Does an offshore tax preparer need a PTIN if a US CPA signs the return? Yes. Non-signing preparers are left off the return, and the IRS says "they still are required to have a PTIN." The requirement depends on whether the person prepares or assists in preparing all or substantially all of a return for compensation.

How does a foreign preparer without an SSN get a PTIN? The preparer registers online and uploads two notarized identity documents from the IRS list. The IRS allows six weeks for review, after which the preparer completes the online application. The fee listed for first-time applications and renewals is $18.75 as of October 2026.

Do clients need to sign a Section 7216 consent if the offshore preparer works for our own firm? Yes. The regulation requires taxpayer consent before disclosure to anyone located outside the United States, including the firm's own employees. Form 1040 consents must include the statements set out in Rev. Proc. 2013-14.

Can an offshore preparer see client Social Security numbers? Only with a consent that includes the longer SSN statement, and only when both the US firm and the offshore preparer maintain an adequate data protection safeguard. Many firms mask SSNs to keep the simpler consent.

When should onboarding start for the 2027 filing season? Start the PTIN identity review by early November 2026, since the IRS review alone can take six weeks. Software access and client consents can then run in parallel with training through December.
