Hungary-based mobile app developers face unique EIN challenges
Mobile app developers in Hungary often encounter the need for a U.S. Employer Identification Number (EIN) when earning revenue through platforms like Apple's App Store or Google Play. Unlike U.S. residents, Hungarian developers typically do not have a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) readily available, which complicates the standard EIN application process. The IRS requires specific documentation and a clear understanding of non-resident application procedures to successfully obtain an EIN. This is particularly relevant as the Hungary-U.S. tax treaty was terminated in 2024, reverting withholding rates to 30% for certain income, making U.S. tax compliance even more critical for Hungarian developers receiving U.S.-sourced income.
This situation creates a specific friction point: the necessity of a U.S. business tax ID for international tax compliance and financial operations, directly conflicting with the lack of a U.S. taxpayer identification number. Without an EIN, developers may face higher withholding taxes on their app revenue and difficulties in opening necessary U.S. business bank accounts. Understanding the nuances of applying as a non-resident is therefore essential for Hungarian mobile app developers to ensure smooth financial operations and compliance with U.S. tax law.
When a Hungarian mobile app developer requires an EIN
An EIN is mandatory for Hungarian mobile app developers primarily when engaging in specific U.S. business activities that necessitate a federal tax ID. The most common trigger for developers is receiving payments from U.S.-based platforms such as the Apple App Store or Google Play Store for app sales or in-app purchases. These platforms are required by the IRS to collect U.S. tax information from foreign developers. To minimize the statutory 30% U.S. withholding tax on this income, developers must provide a U.S. tax identification number, which is typically an EIN for business entities.
Beyond app store revenue, an EIN becomes necessary if a Hungarian developer establishes a U.S. business entity, such as a U.S. LLC, to operate their mobile app business. Opening a U.S. bank account for business purposes is another common requirement, and U.S. banks almost universally require an EIN to open a business account. Furthermore, if the developer plans to hire employees in the U.S. or conduct other significant business operations within the United States, an EIN is a legal prerequisite. Failure to obtain an EIN when required can lead to incorrect tax withholding, penalties, and operational delays.
Required documents for non-resident EIN applications
Non-resident applicants, including mobile app developers from Hungary, must submit specific documentation to the IRS when applying for an EIN using Form SS-4. The primary document is the passport of the responsible party, which is the individual who will manage the EIN application and be listed on the form. This passport serves as the primary identification for the applicant.
In addition to the passport, proof of business formation is required. For developers operating as a U.S. LLC, this would include formation documents like the Articles of Organization and an Operating Agreement. If the business is structured as a foreign entity operating in the U.S., relevant formation documents from Hungary would be needed. Crucially, a U.S. business address is also a common requirement on Form SS-4. Since most non-residents do not have a physical U.S. address, this can be a U.S. virtual office address or a mail forwarding service. It is vital that this address is valid and functional for receiving IRS correspondence. The responsible party must also have a valid mailing address outside the U.S. for IRS communication.
The EIN application process for Hungarian developers
Applying for an EIN as a non-resident developer from Hungary involves a process distinct from that for U.S. residents. Since the responsible party likely does not possess an SSN or ITIN, the standard online application portal, which requires such a number, cannot be used. Instead, the application must be submitted via fax or mail directly to the IRS. This method typically results in a processing time of 3–5 weeks.
The application starts with completing Form SS-4, the Application for Employer Identification Number. This form requires detailed information about the business, including its name, address, type of entity, and the responsible party's information. For non-residents without an SSN, line 7b of Form SS-4, which asks for the SSN or ITIN, should be left blank, and the responsible party should write 'Foreign' in the designated space to indicate they do not have a U.S. taxpayer identification number. After completing the form, it is faxed to the IRS at their dedicated non-resident line. The IRS will then process the application and issue the EIN via fax or mail. The typical turnaround time for this method is 3–5 weeks, although this can vary based on IRS workload.
Common application mistakes for Hungarian mobile app developers
Hungarian mobile app developers often make specific errors when applying for an EIN, stemming from unfamiliarity with U.S. tax procedures and platform requirements. A frequent pitfall is incorrectly filling out line 7b of Form SS-4. When the responsible party does not have an SSN or ITIN, it is essential to write 'Foreign' in the designated field, not leave it blank or enter an incorrect number. Leaving it blank can cause the application to be rejected, while entering an incorrect number can lead to identity verification issues.
Another common mistake is misunderstanding the U.S. business address requirement. Developers may try to use their Hungarian address, which is not acceptable for the business address line on Form SS-4 if the business is intended to operate in the U.S. A valid U.S. mailing address, even a virtual one, is typically required. Furthermore, selecting the wrong entity type on Form SS-4 can have significant tax implications. Developers must accurately identify their business structure, whether it's a U.S. LLC, a foreign corporation, or another entity type, as this impacts tax filings and reporting obligations like Form 5472 for foreign-owned U.S. disregarded entities. Incorrectly filling out the entity type can lead to processing delays or require a new application.
The Certified Acceptance Agent (CAA) path for EIN applications
For non-resident applicants like mobile app developers in Hungary, the process of obtaining an EIN can be expedited and simplified by using a Certified Acceptance Agent. A CAA is an individual or entity appointed by the IRS to assist non-residents in obtaining an EIN. As a designated CAA, itin.net can verify the identity of the applicant and the authenticity of the documentation submitted, acting as a trusted intermediary.
When applying through a CAA, the application process is significantly streamlined. Instead of faxing or mailing Form SS-4 directly to the IRS and waiting several weeks, the CAA can often submit the application electronically or via expedited channels. This can reduce the processing time to as little as 3–5 business days. The CAA's role involves reviewing the application for accuracy, verifying the applicant's identity using their passport and other required documents, and then forwarding the application to the IRS. This significantly reduces the risk of application errors and delays, providing a more reliable and faster path to obtaining the necessary EIN, especially for those unfamiliar with the IRS's non-resident procedures.
Next steps after obtaining your EIN
Once you have successfully obtained your EIN, the next crucial step is to use it for its intended purposes, primarily for U.S. tax compliance and financial operations. For mobile app developers in Hungary, this often means submitting your new EIN to platforms like the Apple App Store and Google Play Store. This action will help ensure that the correct U.S. tax withholding rate (potentially reduced from the default 30% if any applicable treaties were in place, though currently not for Hungary) is applied to your earnings, preventing over-withholding.
Furthermore, if you plan to open a U.S. bank account for your business, your EIN will be a primary requirement for the bank. Accounts with services like Mercury, Relay, or Brex often require an EIN to establish business legitimacy. It is also vital to understand your ongoing U.S. tax obligations. For foreign-owned U.S. entities, this might include filing informational returns such as Form 5472 annually.

- Ensure your U.S. business address is valid and functional for receiving IRS mail, even if it's a virtual office or mail forwarding service.
- Accurately identify your business entity type on Form SS-4 to avoid tax implications and processing delays.
- Consider using a Certified Acceptance Agent (CAA) like itin.net to expedite the EIN application and minimize errors.
Frequently asked questions
Can I apply for an EIN online as a developer in Hungary?
No, you cannot use the standard IRS online EIN application portal if you are a non-resident of the U.S. and do not have an SSN or ITIN. You must apply via fax or mail directly to the IRS, or use the services of a Certified Acceptance Agent (CAA).
How long does it take for a developer in Hungary to get an EIN?
Applying directly to the IRS via fax or mail typically takes 3–5 weeks. Using a Certified Acceptance Agent (CAA) can expedite this process to approximately 3–5 business days.
What if I don't have a U.S. business address as a mobile app developer in Hungary?
You will need a U.S. mailing address for your EIN application. This can be a virtual office address or a mail forwarding service. It must be a functional address where the IRS can send correspondence.
Will I need an ITIN before applying for an EIN?
No, an ITIN is not required to apply for an EIN as a non-resident responsible party. You will indicate on Form SS-4 that you do not have an SSN or ITIN by writing 'Foreign'.
How does the termination of the Hungary-U.S. tax treaty affect my EIN application?
The termination of the treaty means U.S. withholding tax on certain income paid to Hungarian residents reverts to the statutory 30%. While the EIN itself doesn't change this, it's crucial for correctly reporting your income and potentially qualifying for any future treaty benefits or reduced withholding if new agreements are made.
Do I need a U.S. LLC to get an EIN?
Not necessarily. You can obtain an EIN as a foreign individual or a foreign entity even without forming a U.S. LLC. However, if you are earning significant revenue through U.S. platforms, forming a U.S. LLC may offer liability protection and tax advantages, and would require an EIN.
