What our customers say about EIN

Sarah M.

Sarah M.

CEO

As a Ukrainian entrepreneur forming an LLC in Delaware to access US markets, I was overwhelmed by the EIN registration requirements and worried about making mistakes that could delay my business launch. I didn’t have a Social Security Number and wasn’t familiar with IRS procedures or Form SS-4. Lappa’s team made the entire process simple by explaining exactly what I needed as a non-resident, preparing all documentation accurately, and handling all communications with the IRS on my behalf. They obtained my EIN registration service approval in just 12 days, enabling me to open a US bank account and register on Amazon immediately. The multilingual support was invaluable, and their transparent pricing meant no surprises. Highly recommend for international business owners.

We’re a UK-based company expanding into the US market through a Delaware C-Corp structure. Understanding whether we needed EIN for non US company operations and how to apply without US identification numbers was confusing until we found L’Tax. Their experts walked us through the entire process, explained our obligations clearly, and managed the complete application including Form SS-4 preparation and IRS submission. The EIN number registration was approved within 10 business days with zero complications, and we immediately used it to set up our Stripe account and start accepting US payments. The time savings compared to trying to navigate this ourselves was substantial, and the cost was far less than hiring US attorneys.

Their team prepared our application with 98% accuracy as promised, managed all IRS communications, and delivered our EIN in under two weeks. The ability to register on major platforms immediately after receiving our number accelerated our US market entry significantly.

We’re a Canadian corporation establishing a US subsidiary and needed EIN registration quickly to open bank accounts and begin operations on schedule. The complexity of navigating IRS procedures as foreign entities without SSNs was daunting, and we couldn’t afford delays in our expansion timeline. Lappa’s experts streamlined the entire process by preparing flawless Form SS-4 documentation, submitting it through the appropriate channels, and managing all follow-up with the IRS. Our EIN for non US company was approved in 11 days, meeting our critical deadline for bank account opening. The $500 annual savings compared to using traditional legal services was bonus value on top of the time efficiency and peace of mind their expertise provided.

Head of Tax, E-commerce Aggregator

As a Middle Eastern entrepreneur launching a US-based SaaS company, I needed EIN number registration but had no idea how to navigate the application process from abroad. The language barrier, unfamiliarity with US tax procedures, and lack of SSN or ITIN made DIY application seem impossible. L’Tax’s multilingual support team made everything easy by explaining requirements clearly, preparing all documentation in perfect English, and handling the entire IRS submission process on my behalf. They obtained my EIN in exactly 14 days as estimated, enabling me to set up Stripe payment processing and launch my product on schedule.

FAQ about Employer Identification Number

What is EIN registration and which businesses need it

EIN registration is the process of obtaining an Employer Identification Number from the Internal Revenue Service, which serves as a federal tax identification number for businesses operating in the United States. Businesses need EIN registration if they have employees, operate as a corporation or partnership, file employment or excise tax returns, withhold taxes on income paid to non-resident aliens, or have a Keogh retirement plan. Additionally, many banks require an EIN to open business bank accounts, and marketplaces like Amazon, Stripe, and PayPal typically require an EIN for merchant accounts. While sole proprietors without employees can sometimes use their Social Security Number instead, obtaining an EIN registration is recommended for liability protection and professional credibility. The number is issued free by the IRS and remains with the business permanently unless the entity dissolves.

How does the EIN registration service process work

The EIN registration service process begins with consultation to determine your business structure and EIN eligibility, followed by collection of necessary information including business legal name, formation documents, responsible party details, and business classification. Our team then prepares Form SS-4 ensuring all fields are completed accurately according to IRS requirements, reviews the application for errors that commonly cause rejections, and submits it to the IRS through the appropriate channel based on your circumstances. We handle all follow-up communications with the IRS including responding to any requests for additional information or clarification, track your application status throughout the process, and deliver your official EIN documentation once approved. Typical processing through our EIN registration service takes 10-14 business days compared to potentially weeks or months for self-filed applications due to errors or incomplete submissions.

Can I get EIN for non US company without SSN or ITIN

Yes, you can obtain EIN for non US company operations without having a Social Security Number or Individual Taxpayer Identification Number. The IRS allows foreign individuals and entities to apply for an EIN by designating a responsible party who has a valid Taxpayer Identification Number, which can include another entity’s EIN, or by applying through specific IRS procedures designed for international applicants. Our service specializes in helping non-US businesses navigate this process by understanding the alternative documentation requirements, preparing applications that comply with IRS protocols for foreign applicants, and managing the additional verification steps that may be required. Many international business owners successfully obtain EIN for non US company registration through our service even when they have no prior US tax identification, enabling them to establish US business operations, open bank accounts, and register on US platforms without needing to first obtain SSN or ITIN.

How long does EIN number registration typically take

EIN number registration timelines vary depending on application method and accuracy. Through our professional service, typical processing takes 10-14 business days from application submission to EIN issuance, with our 98% accuracy rate minimizing delays from rejections or requests for corrections. Self-filed applications can take significantly longer particularly for international applicants or those with complex business structures, often ranging from 4-8 weeks or more if errors require resubmission. The IRS offers online instant EIN issuance for certain applicants, but this option is only available to those with valid SSNs and during limited business hours, excluding most international applicants and many business structures. Mail applications can take 4-6 weeks even when completed perfectly. Our service accelerates EIN number registration by ensuring applications are accurate from the start, submitted through optimal channels, and professionally managed through any follow-up requirements, providing predictable timelines that support business planning and launch schedules.

What information is required for EIN registration

EIN registration requires specific information about your business and responsible party including the legal name of the entity exactly as it appears on formation documents, business structure type such as LLC, Corporation, Partnership, or Sole Proprietorship, physical address where the business is located which cannot be a PO Box, responsible party information including name and Taxpayer Identification Number which can be SSN, ITIN, or another EIN, reason for applying such as started new business or banking purpose, expected number of employees within the next 12 months, principal business activity description, and the date business started or will start. For foreign entities seeking EIN registration, additional information may include foreign address, reason for needing a US EIN, and details about US business activities. Having formation documents, operating agreements, and articles of incorporation ready helps ensure accurate application completion. Our service guides you through collecting exactly what’s needed for your specific situation.
