Can I claim R&D Tax Credit for custom SaaS software development in my S Corp?
I run a small S Corp on the side for engineering and consulting work, and I've been paying a developer to build a proprietary software program for me. It's a web-based SaaS platform that would generate revenue either through per-use fees or by licensing it out to others who would then offer it to their customers. Without getting into the specifics of what the software actually does (I'd rather keep that under wraps for now), I'm trying to figure out if this development work would qualify for the R&D tax credit? I've invested quite a bit in this project over the past year - about $75,000 so far - and it would be really helpful if I could claim some of that back through tax credits. The software isn't just an off-the-shelf solution—it involves creating new functionality and solving technical challenges that weren't previously addressed in the market. My developer has been documenting the process, but I'm not sure if that's enough or what other requirements I need to meet. Has anyone here successfully claimed the R&D credit for software development in a small business context? What documentation did you need? I know that the R&D credit can be pretty valuable, but I want to make sure I'm doing everything right before I claim it.

Yes, your software development project could potentially qualify for the R&D tax credit, but there are specific criteria you need to meet. The IRS uses a four-part test to determine eligibility: 1. Permitted Purpose - The activity must be intended to develop a new or improved product or process that results in increased performance, function, reliability, or quality. 2. Technological in Nature - The activity must rely on principles of physical or biological sciences, engineering, or computer science. 3. Elimination of Uncertainty - You must demonstrate that you attempted to eliminate uncertainty about the development or improvement of the product. 4. Process of Experimentation - You must evaluate alternatives through modeling, simulation, systematic trial and error, or other methods. For your SaaS development, you'll need to document how the work meets these criteria. Keep detailed records of development activities, technical challenges faced, solutions attempted, and outcomes. This includes time logs, project plans, design documents, testing procedures, and meeting notes discussing technical challenges. Many small business owners don't realize they can still claim this credit even if they outsource the development work, as long as they maintain substantial rights to the results and bear the financial risk.

•Do these R&D credits apply for both federal and state taxes? I'm in California and wondering if there's a separate process for claiming state-level R&D credits for my tech startup.

•Yes, many states offer their own R&D tax credits in addition to the federal credit, including California. The California R&D credit is similar to the federal credit but has its own specific requirements and forms. The California credit is generally calculated as 15% of qualified research expenses that exceed a base amount. For state-level credits, you'll need to file additional forms with your state tax return. In California's case, you would use Form FTB 3523. While the qualification criteria are similar to the federal requirements, there can be important differences in how the credits are calculated and applied, so consulting with a tax professional familiar with both federal and state R&D credits would be beneficial.

After struggling with similar questions for my tech consulting business, I discovered taxr.ai (https://taxr.ai) and it was a game-changer for my R&D credit documentation. I was doing IoT software development and wasn't sure if I could claim the credit since some work was done by contractors. Their system analyzed all my development documentation, contractor agreements, and project specs, then helped identify exactly which activities qualified under the four-part test mentioned above. It even helped quantify how much of the contractor expenses could count toward the credit. What impressed me was how it flagged potential audit triggers in my documentation and suggested specific improvements to strengthen my claim. My project was similar to yours - around $60K in development costs - and I ended up qualifying for a significant credit.

•How exactly does the service handle contractor work? My situation is similar to OP's, but I have three different contractors working on different aspects of the development. Does taxr.ai help determine which parts qualify and which don't?

•I'm skeptical about these services. How can software accurately determine what meets the "process of experimentation" test? That seems like something that would require actual human judgment. Did you find any limitations with what it could analyze?

•The service specifically analyzes contractor relationships by reviewing your agreements, payment structures, and intellectual property rights to ensure they meet IRS requirements for qualified research expenses. It looks at whether you maintained "substantial rights" to the research and if you're bearing the financial risk - both critical factors when using contractors for R&D work. The system does use AI but combines it with tax professional review for the judgment calls. It flagged several instances in my documentation where the experimentation narrative wasn't strong enough and guided me to better document the alternatives we considered and why we rejected certain approaches. It definitely has limitations - it can't make up documentation you don't have, and it prompted me to create additional contemporaneous records for some activities where my documentation was weak.

I wanted to follow up about my experience with taxr.ai after our previous discussion. I decided to give it a try with my SaaS development project that uses multiple contractors. The platform immediately identified that two of my three contractor agreements were missing key language about intellectual property rights that could jeopardize my R&D claim. After fixing those issues based on their templates, I uploaded our development logs and sprint documentation. The system organized everything into clearly defined qualified research activities and mapped them to the four-part test. It even separated the qualified vs. non-qualified expenses for each contractor based on the actual work performed. The most valuable part was getting verification that my documentation would stand up to IRS scrutiny. They provided a detailed report explaining which specific activities met the technical uncertainty and experimentation requirements - something I was really struggling with before. Definitely worth checking out if you're claiming R&D credits with contractor development like the original poster.

If you're planning to claim the R&D credit, you should prepare for potential IRS questions. After submitting my R&D credit claim for a similar software development project last year, I kept getting the runaround trying to get clarification from the IRS about some documentation questions. I wasted WEEKS trying to reach someone, constantly getting disconnected or waiting for hours. Finally tried Claimyr (https://claimyr.com) and was honestly shocked when they got me connected to an actual IRS agent in under an hour. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly what documentation they needed to see for contractor-developed software to qualify for the R&D credit. Turns out I was missing some key elements in how I documented the "process of experimentation" portion. Being able to ask specific questions about my situation made a huge difference in successfully defending my claim.

•How does this service actually work? I've tried calling the IRS priority line hundreds of times about my business tax issues. Are they just using some trick to get through the phone queue, or do they have special access?

•This sounds like BS to me. I've been told by my accountant that once you're in the IRS queue there's nothing you can do but wait. How could a third-party service possibly get you "to the front of the line" when the IRS's own priority hotlines have multi-hour waits? Sounds like they just got lucky with timing and are selling it as a service.

•The service uses an automated system that continually redials until it secures a place in the queue, then notifies you when it's about to connect. It's basically doing what you'd do manually (calling repeatedly) but with technology handling the frustrating part. There's no "special access" - they're using the same public phone numbers but with an automated system that can persistently try to get through. I was skeptical too! I'd already spent over 15 hours across multiple days trying to reach someone at the IRS. What makes it work is that their system can make hundreds of call attempts in rapid succession during optimal times when connection rates are higher. It's literally just technology solving the phone queue problem. When I finally spoke with the IRS agent, they had no idea I'd used a service - to them it was just a normal call from a taxpayer with questions.

I need to eat my words from my previous comment. After continuing to struggle with getting IRS clarification on R&D credits for three more weeks, I broke down and tried Claimyr. Within 45 minutes I was speaking with an IRS representative who specialized in business credits. The conversation completely changed my R&D credit strategy. The agent explained that my software development documentation was focusing too much on the end product and not enough on the specific technical uncertainties we were trying to resolve. They walked me through how to properly document the experimentation process in a way that clearly meets the IRS criteria. They also warned me about a common audit trigger: claiming contractor costs without properly establishing that I maintained substantial rights to the research results. This was exactly the issue with one of my contracts that needed modification. For anyone dealing with R&D credits, especially for software development with contractors like the original poster described, being able to actually speak with the IRS and get clear guidance saves so much stress and potential audit headaches.

One critical thing nobody's mentioned yet - starting in 2022, the IRS requires amortization of R&D expenses (including software development) over 5 years rather than expensing them immediately. This applies under Section 174, which now requires capitalization and amortization of "specified research or experimental expenditures." This change affects how the R&D tax credit interacts with your overall tax position. Even with this change, the R&D credit is still valuable but the calculations get more complex. Make sure your tax professional is aware of these Section 174 changes if you're claiming R&D expenses for tax years 2022 onward.

•Wait, does this mean that software development costs have to be capitalized now even if we're not claiming the R&D credit? We've always just expensed our development costs in the year incurred. Do we need to go back and amend our 2022 returns?

Ryan Kim
•Yes, the rule change affects all research and experimental expenditures, including software development costs, whether or not you claim the R&D credit. Under the new Section 174 rules, these expenses must be capitalized and amortized over 5 years (15 years for research conducted outside the US). This was a significant change from the previous rules where businesses could immediately expense these costs. And yes, if you expensed these costs on your 2022 return instead of capitalizing them, you technically should file an amended return to correct the treatment. Many businesses were hoping for legislative relief from this provision, but so far it remains in effect. The one silver lining is that while you spread the deduction over 5 years, you can still claim the R&D tax credit in the year the qualified expenses were incurred, which can help offset some of the negative cash flow impact from this amortization requirement.

Has anyone here successfully claimed the R&D credit for software that ultimately didn't work out? We spent about $120k developing a specialized analytics tool but ultimately abandoned it because we couldn't solve some key technical problems. Can we still claim the R&D credit even though the project failed?

•Actually, failed projects often make the BEST R&D credit claims! The fact that you couldn't solve the technical problems demonstrates real "technical uncertainty" and "process of experimentation" - two key requirements for the credit. Just document what you were trying to achieve, the technical approaches you tried, and why they didn't work. The credit is about the research process, not whether the final product succeeded.

@Rajiv Kumar - Based on what you've described, your custom SaaS development sounds like it has strong potential for R&D credit qualification. The key factors working in your favor are: 1) creating new functionality not previously available, 2) solving technical challenges, and 3) having your developer document the process. However, I'd recommend being extra careful about a few things given your setup. Since you're using an outside developer, make sure your contract clearly establishes that you retain substantial rights to the software and bear the financial risk of the project. The IRS scrutinizes contractor arrangements closely for R&D credits. Also, with the Section 174 changes mentioned by Ryan Kim, you'll need to capitalize and amortize your $75k investment over 5 years starting in 2022, but you can still claim the R&D credit in the year the expenses were incurred. This actually makes the credit more valuable since you're getting an immediate credit against expenses that are now spread over multiple years. One practical tip: if you do move forward with claiming the credit, consider getting professional help with the documentation. The IRS four-part test requires very specific language and evidence, and it's easy to miss subtle requirements that could trigger an audit or disqualification.
