ChatGPT Enterprise in tax consulting: how HSP GRUPPE boosted productivity

HSP GRUPPE, a German tax law consulting group, has rolled out OpenAI's ChatGPT Enterprise to make its team more efficient. According to a post on the OpenAI Blog, the company increased productivity, improved the quality of its output and freed up more consultant time for direct work with clients.

What changed for tax professionals

ChatGPT Enterprise helps HSP GRUPPE staff handle tax advisory tasks faster and with higher quality. A large share of working time in this profession goes to text-heavy work: analyzing regulations and case law, drafting tax opinions, answering client inquiries, and preparing tax returns and accompanying documentation.

The AI tool takes over the routine workload, letting specialists focus on analysis, expert judgment and direct interaction with clients.

"The company increased productivity, improved the quality of its work and created more opportunities for tax consulting and client service," the official

OpenAI blog says.

Why tax firms need an enterprise version of ChatGPT

Tax firms handle clients' confidential financial data, so the choice of an AI platform is strictly limited to tools with enterprise-grade security. ChatGPT Enterprise differs from the public version of ChatGPT in several key respects:

• Client data and prompts are not used to further train OpenAI's models
• Administrative tools for managing access and users
• Extended context for working with large documents
• Enterprise confidentiality agreements needed to meet regulatory requirements

These are the characteristics that make ChatGPT Enterprise sought after in industries with strict data protection requirements: tax and legal consulting, healthcare and the financial sector.

The trend: AI arrives in professional services

The HSP GRUPPE case fits a broader trend. According to OpenAI, thousands of organizations worldwide now use ChatGPT Enterprise, from startups to Fortune 500 companies. Professional services firms (tax, legal, consulting) are among the most active adopters.

These industries have a high share of text-processing tasks: analyzing regulatory documents, drafting opinions and handling client communications. Such work lends itself well to AI automation, while key professional judgments remain with the specialist.

What this means

Strict regulation of an industry is no longer an insurmountable barrier for AI tools. The HSP GRUPPE case shows that when a platform with enterprise confidentiality guarantees is chosen carefully, tax firms can get a real productivity gain right now, without waiting for specialized industry solutions.
