D&T tax Inc. is a Certified Acceptance Agent (CAA) authorized by the IRS. We are authorized to verify applicants’ original passports, so applicants do not need to mail their original passports to the IRS when applying for an ITIN.

Without our passport certification service, applicants must submit their original Chinese passport along with the ITIN application form to the IRS for a review process that can take 6 to 12 weeks. During this lengthy processing time, applicants would be without their passport, which is highly inconvenient for individuals who frequently travel internationally. Additionally, once the IRS completes its review—regardless of whether the ITIN is approved—the passport will be returned via regular mail, which carries the risk of loss.

Individual Taxpayer Identification Number (ITIN):
The ITIN (Individual Taxpayer Identification Number) is a number issued by the IRS for non-U.S. residents who are required to file taxes in the United States. ITIN issuance does not take immigration status into consideration, so having an ITIN does not impact your non-immigrant or immigrant visa applications.

The ITIN can be used for: filing federal and state taxes, opening a bank account, applying for credit cards, and setting up phone service. (Possession of an ITIN does not prove lawful immigration status in the U.S. and does not qualify the individual for U.S. tax benefits.)

Common individuals who need to apply for an ITIN:
1. U.S. Income Reporting:
1. Individuals with U.S.-based business income, rental income, capital gains, or other investment income
2. U.S. Income Withholding:
1. Required by the IRS for certain withholding or information reporting obligations for non-U.S. residents
2. Non-U.S. residents selling property in the United States

Documents required for an ITIN application:
1. Applicant’s original passport and a photocopy
2. U.S. address (agent’s address is acceptable)
3. Overseas address
4. Date of entry into the United States
