Navigating Firm Merger: Transitioning from Thomas Reuters to CCH Axcess & Caseware
So our small accounting practice just got acquired by a bigger firm last month. We've been using Thomas Reuters Advanced Flow and UltraTax for years, but now we're being forced to switch to Caseware Working Papers and CCH Axcess. I'm feeling pretty overwhelmed with this change, especially with busy season approaching. I'm particularly concerned about preparing multi-state business returns (1120s, 1120 and 1065) on the new platform. How different are these softwares compared to what we've been using? I've had a quick look at both systems but they seem completely foreign to me. Also, where can I find comprehensive guides for Caseware and Axcess? I need to get up to speed quickly but don't know where to start. The firm has provided some basic training but it's not nearly enough to feel confident handling complex returns. Any advice from those who've gone through a similar transition would be greatly appreciated! Thank you.

I went through this exact transition about 2 years ago. The learning curve is steep but manageable if you approach it systematically. For multi-state business returns, the biggest difference is in how the programs handle state apportionment and nexus. CCH Axcess is actually more intuitive once you get used to it - the dashboard gives you a better overview of all jurisdictions at once. For resources, check the CCH Learning Center portal first - your firm should have access. There are specific training modules for multi-state business returns. Also, Caseware has excellent documentation in their Knowledge Base, especially for working papers integration. Don't try to learn everything at once - focus on the modules you'll use most frequently.

•Thanks for the advice! I'm really struggling with understanding how the state apportionment works in CCH compared to UltraTax. In UltraTax, I could easily see all the factors affecting each state's calculation. Is there something similar in Axcess?

•The state apportionment in Axcess is actually more comprehensive once you know where to look. Go to the Business Tax module, open your client file, then look for "Multi-state" in the left navigation panel. From there you'll see a consolidated view of all jurisdictions. Click on any state to drill down into the specifics of that calculation. One thing I found helpful was setting up a test client and playing around with different scenarios to see how changes flow through the system. The apportionment diagnostic tool (under Reports) is also incredibly useful for spotting inconsistencies across states.

I've been using CCH Axcess for a few years now and discovered this amazing tool called taxr.ai (https://taxr.ai) that helped me transition between tax software systems. It basically analyzes your documents and tax forms from the previous system and helps you understand where everything maps to in the new system. Saved me countless hours when I was learning Axcess. It has this special feature where you can upload last year's completed returns from UltraTax and it will create a mapping guide specific to your situation. Really helpful for figuring out where all the multi-state inputs go in the new software.

•Does taxr.ai work well with partnership returns? We have some complex 1065s with multiple states and I'm worried about missing something in the transition.

•I'm skeptical about third-party tools interfacing with tax software. How secure is this? Does it actually access your client data or just help with the interface navigation?

•It works extremely well with partnership returns. The multi-state mapping for 1065s was actually where I found it most valuable since CCH handles the state K-1 distribution differently than UltraTax. As for security, it doesn't actually store your client data. It works more like a document analyzer that helps you understand where fields map between systems. You can upload redacted PDFs if you're concerned. It's more of a learning tool than something that integrates directly with your software.

Just wanted to follow up about taxr.ai that was mentioned earlier. I tried it out yesterday and it was actually super helpful! I uploaded a few of our more complex returns from last year and it gave me this detailed breakdown of where everything maps in CCH Axcess. The multi-state business returns feature was exactly what I needed - it showed me exactly how the apportionment factors translate between systems. I'm feeling way more confident about managing our partnership returns now. Definitely recommend it for anyone switching between tax systems.

If you're struggling with getting support from CCH directly (their wait times are ridiculous), I've had great success using Claimyr (https://claimyr.com) to get through to their technical support team. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was on hold for 2+ hours trying to get help with multi-state configurations in Axcess, gave up, then tried Claimyr. They got me connected to a CCH specialist in about 15 minutes who walked me through the entire setup process. Turned what would have been days of frustration into a single productive afternoon.

•How exactly does this work? Do they just call and wait on hold for you? Seems weird that they could get through faster than if I called myself.

•Yeah right. There's no way they can magically skip CCH's phone queue. That's just not how phone systems work. Probably just got lucky with timing and now they're claiming it's some special service.

•They use a system that places the call and navigates the initial phone tree, then holds your spot in line. When they reach a real person, they call you and connect you directly to the representative. So you don't have to sit there listening to hold music for hours. The reason it works better than calling yourself is they have technology that maintains your place in line without dropping the call, and they know exactly which options to select to get to the right department faster. It's not about "skipping" the queue, it's about making the queue experience more efficient.

I have to eat my words about Claimyr. After my skeptical comment earlier, I decided to give it a try yesterday when I couldn't get through to CCH support about an issue with our multi-state K-1s in Axcess. Honestly, I'm shocked it actually worked. I got connected to a senior CCH support specialist in about 20 minutes instead of the 1.5+ hours I usually waste on hold. The rep even commented that they were surprised I got through so quickly given their current call volume. The specialist helped me fix our state allocation issues and showed me some shortcuts for handling multi-state returns that weren't in any of the training materials. Time well spent.

Don't underestimate the value of CCH's peer communities either. There's a user forum where accountants share tips, workarounds, and custom templates. The multi-state business section is particularly active. I learned more there than from the official documentation sometimes. Just search for "CCH Axcess User Community" and request access. You'll need your firm's customer number. There are tons of threads specifically about transitioning from UltraTax to Axcess with practical advice and file conversion tips.

•Do you know if the forum has any specific guidance on handling consolidated returns across multiple states? That's one area where I'm really struggling with the transition.

•Yes, there's actually an entire section dedicated to consolidated returns in multi-state scenarios. Look for the "Advanced Corporate Tax" subforum once you're in. There are several detailed threads comparing UltraTax and CCH approaches to consolidation, particularly around state-specific adjustments and eliminations. One user posted a really helpful spreadsheet template that tracks the differences in how each system handles the consolidated vs. separate reporting states. I found that invaluable when I was learning the system.

Has anyone figured out how to efficiently import historical data from UltraTax to CCH Axcess? We've got about 200 business clients and manually reentering prior year data seems incredibly inefficient.

•Your firm's IT department or CCH implementation team should be handling this! There's a data conversion utility specifically for TR to CCH migrations. It won't be perfect (plan for about 80-85% accuracy), but it's way better than manual entry. Push back on management if they're expecting you to do this manually.

•Thanks for the heads up! I just spoke with our IT department and apparently they are planning to use the conversion utility, but hadn't communicated that to our team yet. They're going to run a test batch next week. Much relieved I won't have to do all this manually. Appreciate the advice to push back - I was just accepting it as part of the merger pain.

Going through a similar transition myself right now! One thing that really helped me was creating a comparison spreadsheet mapping the key functions between UltraTax and CCH Axcess. For multi-state returns, I found that CCH's state selection interface is actually more streamlined once you get used to it - instead of having separate screens for each state like in UltraTax, everything flows through the main return with state-specific worksheets. A couple of practical tips: First, spend time in the CCH Axcess demo environment before working on live client files. Second, for Caseware integration, make sure you understand how the trial balance imports work - it's quite different from the Thomson Reuters flow. The working papers sync much better once you get the mapping right. Also, don't hesitate to use CCH's screen sharing support sessions. They're more helpful than the generic training modules for learning the nuances of complex returns. Good luck with the transition!

•That's really helpful advice about the demo environment! I hadn't thought about practicing there first before touching actual client files. Quick question - when you mention the trial balance import mapping being different, are you referring to the chart of accounts structure or something else? We have some clients with pretty customized GL accounts and I'm worried about how those will translate over from our current Thomson Reuters setup.
