How do I find reliable tax prep services for an expat with income in more than one country?

Finding a reliable tax prep service for an expat with income in more than one country takes a bit more care than hiring a standard local accountant. Here’s a practical way to vet them:

1) Look for explicit cross-border expertise

Choose someone who regularly handles expatriate and multi-country tax returns, not just “international” in name.

Ask:

• Which countries do you routinely handle?
• Do you prepare both resident and non-resident returns?
• Have you worked with foreign tax credits, tax treaties, and reporting of overseas assets/accounts?
• Do you handle issues like FBAR/FATCA (if relevant), split-year residency, or treaty tie-breakers?

If they can’t answer those confidently, keep looking.

2) Check qualifications in each relevant country

Tax rules vary widely, so credentials matter.

Look for:

• A licensed CPA/EA/Chartered Accountant/Tax Adviser in the relevant country
• Membership in professional bodies
• Experience with the exact countries involved, not just general tax prep

If your situation involves the U.S., a firm experienced with U.S. expat tax is especially important.

3) Verify they know your specific fact pattern

Before hiring, tell them your basics:

• Countries where you earned income
• Whether you’re a citizen/resident of any of them
• Employment vs self-employment vs rental/investment income
• Any foreign bank accounts, stock compensation, pensions, crypto, etc.

A good preparer should explain:

• Which countries you may owe tax to
• How they’ll avoid double taxation
• What forms and deadlines apply
• Whether you need tax filings in more than one jurisdiction

4) Ask how they stay current

Cross-border tax rules change often. Ask:

• How do you keep up with treaty and law changes?
• Do you use local country specialists or refer out when needed?
• Have you handled recent cases with the same countries?

Strong providers will have a process for ongoing research and review.

5) Check reputation carefully

Use multiple sources:

• Online reviews
• Expat forums and communities
• LinkedIn or professional profiles
• Referrals from people in similar situations

Watch for:

• Lots of generic five-star reviews but no real detail
• Promises of unusually large refunds
• “We can get you out of all tax” type claims

6) Ask about scope and pricing upfront

Cross-border returns often cost more because they’re more complex.

Clarify:

• Flat fee vs hourly
• What’s included: planning, filing, amended returns, notices, audit support
• Extra charges for foreign asset reporting or additional country returns
• Communication method and turnaround time

7) Make sure they can coordinate across countries

If your income spans multiple countries, it helps if the preparer can:

• Prepare filings in both places, or
• Work with a trusted local partner in the second country

Coordination matters because one return can affect the other.

8) Red flags to avoid

Be cautious if they:

• Say they “do international taxes” but can’t describe treaty issues
• Don’t ask enough questions about residency and source of income
• Promise guaranteed outcomes
• Seem unfamiliar with foreign reporting obligations
• Refuse to explain their approach in plain language

9) Start with a consultation

A short paid consult can tell you a lot. Bring:

• Last year’s returns
• Income statements from each country
• Visa/residency info
• Dates of move(s)
• Bank/account and investment summaries

A competent expat tax pro should quickly identify your main filing obligations and any risks.

10) Where to look

Good places to search:

• Professional accounting associations
• Expatriate community groups
• Employer relocation providers
• Cross-border tax firms with country-specific pages and case examples

If you want, I can also help you build a checklist of interview questions for tax preparers, or help you screen firms based on the specific countries involved.
