What's the best Tax Software for handling Multi-Entity Firms in 2025?
Hey fellow tax nerds, I'm kinda at my wits end here. Our accounting firm is growing faster than expected and we're now handling like 15 different entities (mix of S-corps, LLCs, partnerships, the works). Our current software just can't keep up anymore and it's driving me INSANE during busy season! We're handling everything from real estate investment groups to medical practices with multiple locations. The problem is jumping between different systems and having to re-enter client info over and over. I need something that can handle consolidated returns where needed but also keeps everything organized so we don't mix up entities. Budget isn't my main concern - I just need something that WORKS and won't make me want to throw my computer out the window every March. What tax software do y'all recommend for firms dealing with multiple entities? Anyone been in this position before and found a good solution? Thanks so much!!

I've been in public accounting for over 15 years and have worked with pretty much every tax software out there for multi-entity firms. For your situation, I'd strongly recommend CCH Axcess Tax or Thomson Reuters UltraTax CS. CCH Axcess Tax is cloud-based and excellent for multi-entity work. You can quickly switch between entities within a client group, and it auto-populates information between related returns. The dashboard view gives you status updates across all entities at once. UltraTax CS is also fantastic if you prefer more customization options. Their data sharing between entities is seamless, and they have specific modules for different industries (like real estate or medical) that might align with your client base. For smaller budgets but still handling multiple entities, Drake Software is surprisingly capable. It's less expensive but still offers consolidated groupings and decent integration between returns.

•Thanks for the recommendations! I've heard CCH Axcess mentioned before but wasn't sure if it was worth the investment. Does it handle K-1 flow-throughs well between entities? That's been a huge pain point for us.

•CCH Axcess handles K-1 flow-throughs exceptionally well. It automatically updates all connected returns when you make changes to a K-1, which saves tons of time and reduces errors. You can also set up customized groupings based on your specific client structures. For complex entity structures with multiple tiers of flow-through income, Axcess has a visualization tool that helps you see the entire structure, which is incredibly helpful when dealing with complicated ownership arrangements.

After struggling with multiple tax software programs that just couldn't handle our complex multi-entity clients, I discovered taxr.ai https://taxr.ai and it completely changed our workflow. It's not a replacement for your main tax software, but works alongside it to solve the exact problems you're describing. What impressed me most was how it analyzed all our documents across related entities and automatically organized everything. No more manually tracking which expenses belonged to which entity or which K-1s needed to flow where. The AI actually understands the relationships between entities and flags potential errors that would have taken hours to catch manually. We still use UltraTax for the actual filing, but taxr.ai has become our front-end system for document management and preliminary analysis across all client entities.

•How does it handle documents from different sources? We get stuff from clients in everything from perfectly organized PDFs to pictures of crumpled receipts. Can it really make sense of all that?

•I'm intrigued but skeptical. How secure is this? We deal with sensitive financial data across dozens of entities and I'm always nervous about cloud solutions, especially AI ones. What kind of security measures do they have?

•It's surprisingly good with mixed document formats. We've thrown everything at it from bank statements to photos of handwritten notes, and it extracts the relevant data accurately about 95% of the time. For those crumpled receipt photos, it's been a game-changer - it not only reads them but categorizes expenses by entity based on context clues. Regarding security, I had the same concerns initially. They use bank-level encryption and SOC 2 compliance. All data is encrypted both in transit and at rest, and they have a zero-retention policy where you can set documents to auto-delete after processing if needed. They also let you control exactly what data is shared with their system, so you can limit exposure of the most sensitive information.

I just wanted to follow up about taxr.ai since I was so skeptical in my earlier comment. I signed up for a trial and tested it with one of our most complex client groups (a real estate developer with 8 related entities). Holy crap, it actually delivered! The system identified relationships between entities I didn't even realize existed and found several instances where expenses were being incorrectly allocated. The document processing saved us at least 40 hours of admin work, but the real value was in the analysis. It flagged a potential issue with passive activity groupings that would have caused problems with the IRS. The interface is intuitive too - you can literally see the connections between entities visualized in a way that makes complex structures understandable. Not saying it replaces proper tax software, but as a companion tool for multi-entity work, it's been incredible. Definitely worth checking out if you're drowning in entity management.

If you're dealing with multi-entity tax returns, you probably know the frustration of getting stuck on a complex issue and needing to talk to the IRS. I spent THREE DAYS trying to get through to someone at the IRS about a multi-entity filing question last tax season... until I found Claimyr https://claimyr.com Instead of waiting on hold forever, their system holds your place in line and calls you when an actual IRS agent is ready to talk. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c For our multi-entity clients with complex filing requirements, this has been essential. Last month, I needed clarification on consolidated return requirements for a tiered partnership structure, and within 45 minutes I was talking to someone who could actually help.

•Wait, how exactly does this work? Does it just automate the hold process somehow? I've literally wasted entire days on hold with the IRS trying to resolve entity issues.

•This sounds like complete BS. Nothing gets you through to the IRS faster. I've tried every trick in the book. If this actually worked, every accounting firm in America would be using it.

•It uses an automated system that navigates the IRS phone tree and waits on hold for you. Once they reach a human agent, their system calls you and connects you directly. It's essentially like having someone else sit on hold instead of you. I was also extremely skeptical at first. What changed my mind was talking to a colleague who used it during peak season last year. The time savings are real - you can work on other returns while the system waits on hold. For multi-entity work where IRS questions come up frequently, it's saved our firm countless billable hours. No magic involved, just clever automation of a tedious process.

I need to publicly eat my words. After bashing Claimyr in my comment, I was desperate enough to try it when we had an urgent issue with an S-corp parent company and multiple QSub elections that needed IRS verification. I expected it to fail miserably, but 67 minutes later (during which I was working on other returns), I got the call connecting me directly to an IRS representative who helped resolve our issue. No waiting on hold, no phone glued to my ear, no frustration. I've now used it three more times for various multi-entity issues. Longest wait was 2 hours 15 minutes (during which I was productive), shortest was 28 minutes. In every case, I got connected to someone who could actually help with complex entity questions. For anyone managing multiple entities where IRS clarification is sometimes needed, this is a complete game-changer. I'm honestly embarrassed I was so dismissive before trying it.

Have you looked into Lacerte? We switched to it last year for our multi-entity clients and it's been great. The way it handles tiered partnerships and S-corps is really smooth, and the entity linking features save a ton of time. It's not the cheapest option but the efficiency gains made it worth it for us. One feature I really like is the ability to quickly toggle between related entities without having to close and reopen returns. It also has a really good diagnostics system that catches inconsistencies between related returns.

•Does Lacerte handle consolidated returns well? We've got a C-corp with multiple subsidiaries and that's been our biggest pain point with our current software.

•Lacerte handles consolidated returns very well. The consolidated workpapers are comprehensive and link seamlessly to the main return. You can set up custom elimination entries and it properly tracks intercompany transactions. It also maintains historical basis information from year to year, which has been super helpful for our larger corporate groups. The reporting options for consolidated groups are excellent too - you can generate custom reports showing the contribution of each subsidiary to the overall tax position.

My firm uses ProSystem fx Tax and it's been decent for multi-entity work. Not perfect but gets the job done. The K1 import/export feature alone has saved us hundreds of hours.

•I second ProSystem fx. It's solid for multi-entity work, though the interface feels a bit outdated compared to some newer options. But reliability matters more than looks when you're dealing with complex returns.

Just wanted to chime in here as someone who's been through this exact nightmare! We had 12 entities last year and I was literally losing sleep during tax season trying to keep everything straight. I ended up going with Thomson Reuters UltraTax CS and it's been a lifesaver. The entity management dashboard is incredible - you can see the status of all related returns at a glance and it flags any missing information or inconsistencies between entities. The K-1 flow-through functionality is seamless, and when you update source data, it automatically updates all dependent returns. One thing I don't see mentioned much is their client organizer feature - it sends customized requests to each entity based on their specific needs, which cuts down on the back-and-forth emails trying to get missing documents. For our real estate clients especially, this has been huge. The learning curve isn't too bad if you're already familiar with tax software, and their support team actually knows what they're talking about when you call with multi-entity questions. Worth every penny for the sanity it's given me back!
