ITIN and State-Specific Requirements: What You Need to Know
Introduction
An ITIN (Individual Taxpayer Identification Number) is issued by the IRS to individuals who are required to file US tax returns but are not eligible for a Social Security Number.
While an ITIN allows access to the federal income tax system, many taxpayers do not realize that state-level tax rules for ITIN holders can differ significantly.State-specific requirements may affect how you file state tax returns, operate a business, or access certain services.
Understanding these differences is essential to remain compliant and avoid penalties. At Ebizfiling, we help ITIN holders navigate both federal and state tax obligations with clarity and confidence.
What Is an ITIN and Why Is It Issued?
An ITIN number is a nine-digit tax identification number issued by the IRS using Form W-7. It is meant only for tax reporting purposes and does not provide work authorization, immigration status, or Social Security benefits.
ITINs are commonly used by:
- Non-resident individuals earning US income
- Foreign students receiving taxable scholarships
- Dependents or spouses of visa holders
- Foreign property owners earning US rental income
While ITINs enable federal tax compliance, state tax obligations are governed separately.
Do States Have Separate Rules for ITIN Holders?
Yes. The IRS does not impose rules on how states treat ITIN holders. Each state determines its own tax and compliance requirements.
- State-level rules may affect:
- State income tax filing
- Business registration and licensing
- Rental income reporting
- Access to state benefits or credits
There is no uniform rule across all states, which is why state-specific research is important.
State Income Tax Filing for ITIN Holders
Many states require ITIN holders to file state income tax returns if income is sourced within that state.
Common income types triggering state filing:
- Wages earned in the state
- Freelance or contract income
- Rental income from property
- Interest or investment income
Even if no federal tax is due, state filing may still be required depending on residency and income thresholds.
Business Ownership and ITIN Holders
ITIN holders are generally allowed to:
- Own LLCs or corporations
- Operate sole proprietorships
- Earn US business income
However, some states may impose additional licensing or reporting requirements. Business income earned within a state can also create state tax filing obligations, even for non-residents.
Ebizfiling helps ITIN holders understand:
- State registration requirements
- Ongoing compliance obligations
- Federal and state reporting alignment
Common State-Specific ITIN Scenarios
- Working in a US State
If you earn income in a state, you may be required to file a state tax return there, regardless of your federal tax liability. - Owning Rental Property
States often require non-resident ITIN holders to file returns on rental income generated within the state. - Students with Scholarships
Some states treat certain scholarship income as taxable. State rules vary and must be reviewed carefully.
ITIN Validity and Renewal
ITINs expire if not used for three consecutive tax years. An expired ITIN can delay refunds and cause return rejections. Renewal is done using Form W-7, and supporting documentation must meet IRS standards. Ebizfiling assists with both new ITIN applications and renewals to avoid processing delays.
How to Check Your State’s ITIN Requirements?
The most reliable sources include:
- Official state Department of Revenue websites
- State income tax instructions
- Direct communication with state tax authorities
Because rules differ by state and situation, professional guidance is often recommended.

FAQs on ITIN and State-Specific Requirements
1. Can I apply for an EIN number while living outside the US?
Yes, you can apply for an EIN number even if you live outside the United States. The IRS allows foreign individuals and companies to apply, provided the business is registered in the US and the application is submitted using the correct method.
2. Do I need a Social Security Number to apply for an EIN?
No, a Social Security Number is not mandatory for foreign applicants. If you do not have an SSN or ITIN, you can still apply for an EIN by mentioning “Foreign” in the responsible party section of the EIN application.
3. What is the EIN application process for non-US residents?
Non-US residents must apply for an EIN using IRS Form SS-4. Since the online IRS portal is not available to foreign applicants, the form is submitted via fax or by calling the IRS directly.
4. How long does it take to get an EIN from outside the US?
Processing time depends on the application method. Phone applications may result in immediate EIN issuance, while fax submissions usually take a few weeks. Errors or missing information can cause delays.
5. Can I apply for an EIN before opening a US bank account?
Yes, an EIN is required before opening a US business bank account. Banks typically ask for the EIN confirmation letter issued by the IRS to verify your business identity.
6. Is an EIN required if my US company has no employees?
Yes, most US business entities such as LLCs and corporations require an EIN even if they do not have employees. It is needed for tax filings, banking, and payment processing.
7. What documents are needed to apply for an EIN number?
You mainly need completed Form SS-4 with accurate business details. In most cases, no supporting documents are required, but the information must match your US company records.
8. Can a foreign individual be listed as the responsible party?
Yes, a foreign individual can be the responsible party for the EIN application. The IRS allows non-US residents to act as responsible parties as long as the information provided is accurate.
9. What happens if my EIN application is rejected?
If an EIN application is rejected, it is usually due to incorrect details or missing information. The application can be corrected and resubmitted, but this may increase processing time.
10. How can Ebizfiling help with EIN application from outside the US?
Ebizfiling assists foreign founders by preparing Form SS-4 correctly, submitting the EIN application through the appropriate IRS channel, and tracking the process until the EIN number is issued.
