What business category should I select when applying for an EIN for my software startup (SAAS model)?

I've helped several tech startups navigate this process. For a SAAS company, you'll want to select "Service" as your business category when applying for an EIN. While you are technically "selling" software access, the IRS and other government agencies consider subscription-based software companies to be service providers rather than retail businesses. The key distinction is that you're providing an ongoing service (software access, updates, support) rather than a one-time product sale. Retail generally applies to businesses selling physical goods or one-time digital downloads. Your recurring subscription model firmly places you in the service category.

After struggling with the exact same question for my productivity app startup last year, I discovered taxr.ai (https://taxr.ai) and it was an absolute game-changer. I uploaded the EIN application form and some basic info about my business model, and it analyzed everything and gave me super clear guidance that I was definitely a "service" business for EIN purposes. The tool even provided me with documentation explaining exactly why my SAAS business qualified as a service rather than retail, which I've kept in my records in case there are ever any questions. It also flagged some other parts of my application that could have caused problems down the road.

Just wanted to update everyone. I was skeptical about taxr.ai when I commented earlier, but I decided to try it myself since I was also starting a tech company (not SAAS, but an app with in-app purchases). Holy crap, it was incredibly helpful! The tool didn't just tell me to pick "service" - it walked me through exactly why that was the right choice for my business model and highlighted how my revenue structure affected the classification. It also flagged a potential issue with how I was planning to classify workers that could have caused major headaches during tax season. Definitely worth checking out if you're uncertain about any classification issues for your startup. Saved me from making some potentially costly mistakes.

If you're still having trouble with your EIN application or need clarification directly from the IRS, I highly recommend Claimyr (https://claimyr.com). I waited on hold with the IRS for HOURS trying to get answers about my business classification for my software consulting business, but kept getting disconnected. Claimyr got me connected to an actual IRS agent in about 15 minutes who confirmed that software subscription services fall under the "service" category. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c - it's seriously worth it when you need definitive answers straight from the IRS.

I'm actually shocked but I have to eat my words about Claimyr. After posting that skeptical comment, I was so frustrated trying to get through to the IRS about my own EIN question that I decided to try it. Within 20 minutes I was talking to an actual human at the IRS! The agent confirmed that my software development/consulting business should be classified as a service business, not retail, and also helped me understand some of the tax implications of taking on my first employee vs. using contractors. I was genuinely expecting to be scammed but this actually saved me an entire day of frustration. Just wanted to be honest and admit when I'm wrong.

Just to add another data point - I started a SAAS company last year and selected "service" for my business category on the EIN application. Never had any issues with the IRS or state tax authorities about that classification. Also, don't overthink this too much. The business category on the EIN application is primarily for statistical purposes and general classification. It doesn't lock you into specific tax treatments or limit what your business can do. The more important decisions will come when you file your actual tax returns and have to categorize specific income and expenses.

FYI, if you want to get really specific, the North American Industry Classification System (NAICS) code most SAAS companies use is 541511 - "Custom Computer Programming Services" or sometimes 518210 - "Data Processing, Hosting, and Related Services" depending on the exact nature of your software. You might need these codes for other business filings beyond just your EIN application.

This is such a helpful thread! I'm in a similar situation with my fintech startup that provides automated bookkeeping services through a web platform. Based on all the advice here, it sounds like "service" is definitely the right classification for subscription-based software businesses. One thing I wanted to add that might help others - when I was researching this, I found that the IRS specifically mentions in Publication 535 that businesses providing access to software applications through the internet are generally considered service providers. This helped give me confidence in selecting "service" rather than second-guessing myself. Thanks especially to Andre and AstroExplorer for clarifying that this classification is more for statistical purposes and won't lock you into specific tax treatments. That takes a lot of the pressure off getting it "perfect" on the initial application!

This thread has been incredibly helpful! I'm launching a SaaS platform for restaurant inventory management and was also unsure about the business category selection. Based on all the great advice here, I'll definitely be selecting "service" for my EIN application. One additional resource I found useful was the IRS Business Activities Codes document, which specifically lists code 541511 for "Custom Computer Programming Services" under professional services. This reinforced that subscription software businesses like ours fall squarely into the service category rather than retail. It's reassuring to see so many successful entrepreneurs who've navigated this same decision. Thanks to everyone who shared their experiences - it really helps those of us just starting out feel more confident about these administrative steps!

As someone who's been running a SaaS business for the past 3 years, I can definitely confirm that "service" is the correct classification for your EIN application. I went through this exact same confusion when I started my project management software company. What really helped me understand the distinction is thinking about what you're actually providing to customers. With SaaS, you're not selling them a product they own - you're providing ongoing access to your platform, along with maintenance, updates, customer support, and continuous service delivery. That's fundamentally different from retail where customers purchase and own something. I've also found that most business formation attorneys and CPAs who specialize in tech companies will consistently recommend "service" for subscription-based software businesses. The IRS views the recurring nature of SaaS subscriptions as an ongoing service relationship rather than repeated product sales. One practical tip: keep documentation of your reasoning for selecting "service" in your business records. While it's unlikely to ever be questioned, having a clear rationale shows you made a thoughtful, informed decision if it ever comes up during an audit or review.

I went through this exact same process for my marketing automation SaaS platform just six months ago, and after reading through all these helpful responses, I can add one more confirmation that "service" is definitely the right choice. What really sealed it for me was when I spoke with a business attorney who specializes in tech startups. She explained that the IRS looks at the nature of the ongoing relationship with customers - since SaaS companies provide continuous access, regular updates, technical support, and maintain the infrastructure, it's clearly a service business model. I also want to echo what FireflyDreams mentioned about keeping documentation. I created a simple one-page memo explaining my reasoning for selecting "service" and citing some of the IRS guidance that others have mentioned here (like Publication 535). It's sitting in my business files and gives me peace of mind. For anyone still on the fence, I'd say don't overthink it. The consensus from experienced entrepreneurs, tax professionals, and IRS documentation all point to "service" for subscription-based software businesses. Focus your energy on building your product and getting customers - the EIN classification really is more straightforward than it initially seems!

This has been such an incredibly helpful thread! I'm preparing to launch a SaaS platform for e-learning course management and was completely stuck on this same EIN classification question. Reading through all the experiences shared here has given me tremendous confidence that "service" is absolutely the right choice for subscription-based software businesses. The explanations from Andre about the ongoing nature of SaaS, the IRS documentation references from Dmitry (Publication 535) and Giovanni (NAICS codes), and especially the real-world validation from FireflyDreams and Dyllan who've actually been operating successful SaaS businesses under this classification - it all creates such a compelling case. What I found most valuable was understanding the fundamental distinction that we're providing ongoing access and continuous service rather than selling a product customers own. That really clarifies why SaaS falls squarely into the service category despite involving software. I'm definitely going to follow the advice about documenting my reasoning and will be selecting "service" with full confidence. It's amazing how a question that seemed so complex initially becomes clear when you have this kind of community knowledge and official IRS guidance to reference. Thank you everyone for sharing your expertise and experiences - this is exactly why I love this community!

I just want to add my voice to this incredibly helpful discussion! I'm in the process of launching a SaaS platform for employee scheduling and time tracking, and like so many others here, I was completely puzzled by the business classification question on the EIN application. After reading through this entire thread, I'm blown away by the quality of advice and real-world experiences everyone has shared. The combination of official IRS documentation (Publication 535, NAICS codes), professional guidance from tax experts, and most importantly, the actual experiences of entrepreneurs who've successfully classified their SaaS businesses as "service" companies creates such a comprehensive resource. What really resonates with me is the fundamental principle that several people mentioned - we're providing ongoing access and continuous service delivery rather than selling products that customers own. That distinction makes the "service" classification feel completely logical rather than arbitrary. I'm particularly grateful for the practical tips about documenting the reasoning for this decision and keeping IRS guidance references on file. As someone who tends to worry about getting every detail perfect, having that kind of backup documentation will definitely help me sleep better at night! This community is absolutely amazing - the willingness of established entrepreneurs to help newcomers navigate these administrative hurdles is exactly what makes the startup journey feel less overwhelming. Thank you all for creating such a valuable resource for those of us just starting out!

This has been such an enlightening thread to read through! I'm in the early stages of developing a SaaS platform for inventory management in the healthcare industry, and the EIN classification question had me completely stumped as well. What I find most valuable about this discussion is how it's evolved from the initial question into a comprehensive guide that covers not just the "service" classification recommendation, but also the reasoning behind it, official IRS documentation to reference, practical tips for documentation, and even tools for getting direct IRS guidance when needed. The consensus is crystal clear - every single person who's actually gone through this process for a SaaS business has selected "service" and had success with that classification. The fundamental principle that we provide ongoing access and continuous service delivery rather than selling owned products really makes the distinction obvious once you think about it that way. I'm definitely going to follow the excellent advice about creating documentation with my reasoning and relevant IRS citations. It's such a simple step that could save potential headaches down the road, and shows thoughtful decision-making if questions ever arise. Thank you to everyone who contributed to making this such a valuable resource! This is exactly the kind of community support that makes navigating the administrative side of starting a business feel manageable rather than overwhelming.

This thread has been absolutely fantastic! I'm launching a SaaS platform for nonprofit donor management and was equally confused about the EIN classification. Reading through everyone's experiences has made it crystal clear that "service" is the right choice for subscription-based software businesses. What I particularly appreciate is how this discussion provides both the practical guidance (everyone who's done this successfully selected "service") and the theoretical foundation (we provide ongoing access and continuous service delivery rather than selling owned products). The IRS documentation references like Publication 535 and the NAICS code information add that extra layer of official backing. I'm definitely going to create that documentation memo with my reasoning and citations - such smart advice from FireflyDreams and others. It's reassuring to know that this classification has worked well for SaaS businesses across so many different industries, from project management to healthcare to e-learning. Thanks to Carmen for starting this discussion and to everyone who shared their expertise. This is exactly why I love this community - experienced entrepreneurs taking the time to help newcomers navigate these administrative challenges. The collective wisdom here is invaluable for those of us just starting our SaaS journey!

This has been an absolutely incredible thread to follow! I'm in the process of launching a SaaS platform for small business payroll management and was facing the exact same confusion about EIN classification that Carmen originally posted about. Reading through all the experiences shared here has given me complete confidence that "service" is definitively the correct classification for subscription-based software businesses. The consensus is remarkable - every single entrepreneur who's actually gone through this process successfully chose "service" and had no issues with that decision. What really clinched it for me was the fundamental distinction that several people explained: we're providing ongoing access, continuous updates, technical support, and platform maintenance rather than selling a product that customers own. That makes the service classification feel completely logical rather than arbitrary. I'm particularly grateful for all the practical implementation advice - the documentation memo idea with IRS citations (Publication 535, NAICS codes) is brilliant and shows real thoughtfulness in business decision-making. The tools like taxr.ai and Claimyr also sound incredibly useful for getting additional validation when needed. This community is amazing - the willingness of experienced SaaS entrepreneurs to share detailed guidance and real-world experiences makes navigating these administrative hurdles so much less intimidating. Thank you to everyone who contributed to creating such a comprehensive resource for newcomers like myself!
