Automating tax workflows with APIs

One of the most exciting things happening in our industry right now is the convergence of automation, AI, and open integration. But for AI to be successful, it needs data. At Wolters Kluwer, our CCH Axcess™ API strategy is all about giving firms access to their data so they can unlock new efficiencies, build smarter workflows, and ultimately deliver more value to their clients.

The three pillars of our API strategy

When I think about our API strategy, I break it down into three tiers:

1. Direct API licensing

Many firms choose to license our APIs directly to build their own custom solutions. We offer APIs for tax data, client and staff data, e-filing, return printing, roll-forward automation, and more. These APIs allow firms to access data and functionality without needing users to be in the application.

For example, I’ve worked with a firm that processes over 50,000 returns a year. They were spending 20–30 minutes per return just assembling PDFs. By implementing our Print APIs, they cut that down to about 2,000 hours annually, a massive time savings. What used to take a full day now takes minutes, and reviewers get returns back while the details are still fresh.

2. Prebuilt tools that leverage our APIs

Not every firm has in-house developers, and that’s okay. We’ve built a toolbox of utilities, many in collaboration with firms, that handle common tasks like K-1 imports, batch roll-forwards, e-filing extensions, and even creating training returns in bulk. These tools use the same APIs but require no development effort from the firm.

3. The CCH Axcess Marketplace

This is where we partner with key vendors that our customers already use, whether it’s for data ingestion, document management, or return delivery. Rather than asking every firm to build their own integration with these vendors, we work directly with them to create standardized, supported integrations. That way, firms can plug into the tools they already rely on, without reinventing the wheel.

The developer portal: your API command center

All of this is tied together through our developer portal. It’s where your developers can explore documentation, test API calls, and see exactly how data flows in and out of the system. It’s a centralized, hands-on resource that makes it easier to get started and scale up.

Looking ahead: Embedded experiences and real-time collaboration

As CCH Axcess continues to evolve as a cloud-native platform, we’re exploring ways to embed parts of the application directly into your firm’s systems. Imagine being able to surface government forms or worksheets right inside your own applications alongside your AI tools and workpapers. This kind of embedded experience would allow multiple users to collaborate in real time, with data flowing seamlessly between systems.

Start small, win big

When firms begin their API journey, there’s often a temptation to tackle the biggest problem first. But I recommend starting with something small and repeatable, something that gets you comfortable with how APIs work. Once you’ve got that foundation, you can scale up to more complex use cases.

For example, printing returns might not seem like a top priority, but it’s a high-volume, repetitive task that’s ripe for automation. And the time savings can be enormous.

Standardization is key

If you want your systems to talk to each other, standardization is critical. A client ID in System A should match the client ID in System B. Otherwise, you’re stuck managing lookup tables or spreadsheets to reconcile data. Our APIs even allow you to update client IDs on the fly, making it easier to align your systems.

The end goal: No-touch tax returns

Ultimately, many firms are aiming for “no-touch” tax return automation, especially for simpler returns. With the right data and the right APIs, you can extract, classify, and import data directly into the return. That frees up your preparers to focus on review and advisory work, not data entry.

Whether you’re integrating your CRM, automating e-file status updates, or building a custom workflow, APIs are the bridge. They connect your systems, reduce manual effort, and help your firm move faster and smarter.
