US FEDERAL TAX SETUP & COMPLIANCE
Complete federal tax ID registration and ongoing compliance — from EIN application to annual federal filings. Our EIN registration services US get foreign-owned entities, US startups and new businesses registered and compliant from day one.
An Employer Identification Number (EIN) — also called a Federal Tax ID — is a unique 9-digit number issued by the IRS to identify a business entity for federal tax purposes. It functions like a Social Security Number for a business, and is required to open a US bank account, hire employees, file federal tax returns, and in many cases, to be taken seriously by vendors and partners.
Our federal tax ID registration service handles the complete application process — a task that is straightforward for a US resident with an SSN, but considerably more complex (and prone to delay) for foreign nationals and foreign-owned entities without one.
Our EIN registration services US serve:
Indian, UK and other foreign founders setting up a Delaware C-corp or LLC for US operations — where obtaining an EIN without an SSN or ITIN requires a specific IRS process.
Newly formed LLCs, corporations and partnerships that need a Federal Tax ID before opening a business bank account, hiring staff, or filing their first tax return.
Even single-owner LLCs without employees often need an EIN — required by most banks to open a business account, and necessary if the LLC elects corporate taxation.
Non-profit organisations applying for tax-exempt status, and trusts or estates requiring a Federal Tax ID separate from the grantor's or decedent's SSN.
Businesses converting entity type (e.g., LLC to corporation), undergoing a merger, or restructuring ownership — situations that often require a new EIN under IRS rules.
Any business hiring its first employee — an EIN is mandatory before payroll tax withholding, reporting and remittance obligations can begin.
Obtaining an EIN without a US Social Security Number is where most foreign founders get stuck. The IRS's online EIN application (the fastest method) is only available to applicants with a valid SSN or ITIN — foreign applicants must instead complete Form SS-4 and submit it by fax or phone, a process with its own specific requirements and common points of rejection.
Our federal tax ID registration service specifically handles the foreign-founder EIN process — correctly completing Form SS-4 (including the "Responsible Party" field, which frequently causes rejections when filled out incorrectly), and following up with the IRS International EIN unit directly. We have processed this exact scenario repeatedly for Indian founders setting up Delaware entities, and know precisely which fields and phrasing cause delays.
Beyond initial registration, our federal tax return filing services ensure ongoing compliance for your entity:
We confirm your entity type, ownership structure and whether the responsible party has an SSN/ITIN — determining whether the online or fax/phone application route applies.
We prepare Form SS-4 with all fields completed correctly — a common source of IRS rejections when self-filed, particularly around the responsible party and business activity fields.
We submit via the fastest available method (online, fax or phone based on eligibility) and follow up directly with the IRS if processing is delayed beyond the expected timeline.
Once issued, we provide the EIN confirmation letter (CP 575) and guide you through using it to open a bank account and register for any required state tax accounts.
We set up your federal tax filing calendar — entity returns, payroll filings, information returns — so you never miss a federal deadline going forward.
As a federal tax compliance consultant with a specific focus on India-US business setups, AAPT & Associates has processed EIN applications for foreign founders more times than most US-based firms — because it is a routine part of our practice, not an occasional edge case. Our federal tax return filing services then carry that entity through its ongoing compliance lifecycle — entity returns, payroll, and information reporting — so the same team that got you registered keeps you compliant every year after.
Since foreign nationals without an SSN or ITIN cannot use the IRS's online EIN application, they must complete Form SS-4 and submit it by fax or phone. Our federal tax ID registration service handles this exact process — correctly completing the form and following up with the IRS International EIN unit to get your EIN issued.
US applicants with an SSN can get an EIN instantly via the IRS online application. Foreign applicants without an SSN or ITIN typically receive their EIN within 5 to 10 business days via fax submission, though phone applications can sometimes be issued the same day. Our EIN registration services US minimise delays by ensuring the application is complete and correct the first time.
No — the IRS does not charge a fee to issue an EIN. Be cautious of third-party websites that charge for "EIN registration" — this is government-issued and free directly from the IRS. Our federal tax ID registration service fee covers our preparation and filing assistance, not any government charge.
Not always required by the IRS (a single-member LLC can sometimes use the owner's SSN), but nearly always required in practice — most banks will not open a business account without an EIN, and it separates your business identity from your personal SSN for privacy and liability purposes.
This depends on your entity type: C-corps file Form 1120, S-corps file Form 1120-S, partnerships file Form 1065, and single-member LLCs typically file Schedule C with the owner's Form 1040. Our federal tax return filing services handle the appropriate return type based on your specific entity election.
EIN applications are commonly rejected due to incomplete responsible-party information, mismatched entity names, or missing signature/authorisation details. As your federal tax compliance consultant, AAPT reviews and corrects the application before resubmission — resolving the specific rejection reason rather than repeating the same error.
No bank account, no payroll, no tax filing is possible without one. Talk to our team — we handle the exact SS-4 process foreign founders need.
