What Is an IRS Certified Acceptance Agent and Why Do You Need One?
An IRS Certified Acceptance Agent (CAA)Â is an individual or business authorized by the Internal Revenue Service to assist applicants with obtaining an Individual Taxpayer Identification Number (ITIN). Unlike standard tax preparers, a CAA has the legal authority to verify your identity documents, such as your passport, and certify copies for the IRS. This means you never have to send your original passport through the mail.
For US expats living in the UK, UAE, Singapore, India, Germany, France, Australia, the Philippines, Malaysia, Belgium, Israel, Saudi Arabia, Qatar, or anywhere else, a CAA is the safest and most efficient way to obtain or renew your ITIN and file your US tax return.

Technical Expertise: Why a CAA Is Superior to a Standard Tax Preparer
Not all tax professionals are created equal. Here is what sets a Certified Acceptance Agent apart:
Identity Verification Authority: A CAA is the only professional outside of the IRS itself or a US embassy who can verify your passport and supporting documents for an ITIN application. Standard preparers cannot do this.
Passport Certification Power: A CAA certifies copies of your passport, eliminating the need to mail the original to the IRS. Your passport stays safely in your hands.
Direct IRS Submission: Your Form W-7, certified documents, and associated tax return are submitted directly to the IRS ITIN unit, reducing processing errors and delays.
Dual Expertise: Our team combines CAA authority with Enrolled Agent (EA) credentials, providing end-to-end service from ITIN application through full US tax compliance.
CAA vs. Standard Filing: A Side-by-Side Comparison
Feature | Certified Acceptance Agent (CAA) | Standard Tax Preparer |
Passport Verification | Yes – Verifies and certifies in person | No – Must mail original to IRS |
ITIN Application (W-7) | Full preparation and submission | Limited or no ITIN expertise |
IRS Authorization | IRS-approved and audited | No special IRS authorization |
Processing Speed | Faster – certified docs accepted immediately | Slower – IRS must verify originals |
Document Safety | Passport never leaves your hands | Risk of loss in international mail |
Tax Return Filing | Combined W-7 + 1040/1040NR filing | Tax return only; ITIN handled separately |
What Documents Do I Need for an ITIN Application?
To apply for an ITIN through a Certified Acceptance Agent, you will need to provide:
Valid Passport: The primary identification document. Your CAA will verify it in person and certify a copy.
Completed Form W-7: Application for IRS Individual Taxpayer Identification Number. Your CAA prepares this for you.
US Federal Tax Return: Form 1040, 1040NR, or the applicable return that requires the ITIN.
Supporting Documentation: Depending on your situation, this may include a foreign tax return, treaty benefit claim, proof of US income (W-2, 1099, K-1), or other relevant records.
Reason for Applying: Documentation supporting your ITIN need, such as tax treaty benefits, real estate transactions, or investment income.
Where Is the Best IRS Acceptance Agent for Expats Worldwide?
Our IRS-approved Certified Acceptance Agent team serves clients across multiple countries with local offices and remote service capabilities. With 13+ years of experience and a 5-star Google rating, we provide expert ITIN and US tax services tailored to each region.
United Kingdom and Europe
Based in London, our UK office serves US expats and foreign nationals across England, Scotland, Wales, and Northern Ireland, as well as clients in Paris, Berlin, Brussels, and throughout Europe. Key considerations for UK and European clients include:
US-UK Tax Treaty: Provisions to avoid double taxation on income, pensions, and capital gains. Articles 1 through 29 of the treaty may reduce or eliminate US withholding on UK-sourced income.
FATCA Reporting: US persons holding UK bank accounts, ISAs, SIPPs, and other financial accounts must report under FATCA.
FBAR (FinCEN 114): US citizens and green card holders in the UK, Germany, France, Belgium, and other EU countries must file FBAR if foreign account balances exceed $10,000 at any point during the year.
US-Germany Tax Treaty: Specific provisions for pensions, dividends, and employment income. German residents with US tax obligations benefit from our dual-jurisdiction expertise.
Belgium and France: Complex social security totalization agreements and tax treaty provisions require careful coordination between US and local tax obligations.
United Arab Emirates, Saudi Arabia, and the Middle East
Our Dubai and Riyadh/Khobar offices serve US expats and foreign nationals across the UAE, Saudi Arabia, Qatar (Doha), Bahrain, Oman, and Kuwait. Critical considerations:
No Local Income Tax: While the UAE and most Gulf states do not impose personal income tax, US citizens and green card holders remain fully subject to US federal taxation on worldwide income.
Foreign Earned Income Exclusion: Qualifying expats in Dubai, Abu Dhabi, Riyadh, Jeddah, and Doha may exclude up to $126,500 (2024) of foreign earned income using Form 2555.
ITIN for Property Investors: Foreign nationals from the Middle East investing in US real estate need an ITIN for FIRPTA compliance, rental income reporting, and treaty benefit claims.
FBAR Compliance: US persons with accounts at Emirates NBD, ADCB, Al Rajhi, QNB, and other regional banks must file FBAR.
Singapore, India, and Asia-Pacific
Our Singapore and Bangalore/Chennai offices serve high-net-worth individuals, foreign investors, and US expats across Southeast Asia and the Indian subcontinent.
US-India Tax Treaty: Important provisions on dividends, royalties, capital gains, and technical services fees. Indian residents receiving US-source income can claim treaty benefits with a valid ITIN.
No US-Singapore Tax Treaty: There is no income tax treaty between the United States and Singapore. This means US expats and foreign nationals cannot claim treaty-based reductions on withholding or double taxation relief through a bilateral agreement. Proper tax planning, including the Foreign Earned Income Exclusion and Foreign Tax Credit, becomes critical for individuals with ties to both countries.
ITIN for Investment Income: Foreign nationals in Singapore, India, and the region investing in US equities, mutual funds, or real estate need an ITIN to claim reduced withholding rates on dividends and royalties.
High-Net-Worth Planning: Complex cross-border structures involving trusts, partnerships, and corporate holdings require integrated US tax compliance.
Australia and the Philippines
US expats in Sydney, Melbourne, Manila, Cebu, and across the region face unique tax challenges:
US-Australia Tax Treaty: Comprehensive provisions covering superannuation, capital gains, and employment income. Australian super funds present unique US reporting challenges.
US-Philippines Tax Treaty: Provisions on dividends, interest, royalties, and business profits. Filipino nationals with US income benefit from CAA services for efficient ITIN processing.
Timing Zone Advantage: Our global office network ensures support across all time zones, with local representatives available for in-person document verification.

Frequently Asked Questions
How do I get an ITIN without sending my passport to the IRS?
Visit an IRS Certified Acceptance Agent. The CAA verifies your passport in person, certifies a copy, and submits it with your Form W-7 application. Your original passport never leaves your possession.
How long does it take to get an ITIN through a Certified Acceptance Agent?
The IRS typically processes ITIN applications within 7 to 11 weeks from the date of submission. Filing through a CAA avoids additional delays caused by mailing original documents and waiting for their return.
Can I file a US tax return without an ITIN or Social Security Number?
You cannot e-file without a valid ITIN or SSN. However, a Certified Acceptance Agent can submit your ITIN application (Form W-7) together with your tax return as a single package, ensuring both are processed efficiently.
Do I need to file US taxes if I live overseas?
Yes. US citizens and green card holders must file US federal tax returns regardless of where they live or earn income. Nonresident aliens must file if they have US-source income. Tax treaties may reduce or eliminate double taxation.
What is the difference between an ITIN and a Social Security Number?
A Social Security Number (SSN) is issued to US citizens and authorized workers. An ITIN is a tax processing number issued to individuals who are not eligible for an SSN but have a US tax filing requirement. Both are nine-digit numbers used for tax purposes.
Can a Certified Acceptance Agent help with ITIN renewal?
Yes. ITINs that have not been used on a tax return for three consecutive years or that have expired based on their middle digits must be renewed. A CAA can verify your documents and submit the renewal application.
