Overview

“ChatGPT for Tax Advisers” is designed for roles such as Tax advisers and practice owners, Tax assistants and tax technicians and Accountants working in tax practices and shows step by step how to use ChatGPT productively, safely and transparently in Tax Advisory – from the fundamentals to advanced workflows.

For many business teams, ChatGPT is the first AI tool they use every day – yet there is a methodical gap between asking the odd question and achieving real productivity gains. In this hands-on day you learn to apply ChatGPT deliberately to recurring work: drafting and editing text, summarising documents, analysing spreadsheets and structuring decision papers. You work with Projects that keep files and instructions together, with Canvas for reworking longer documents, and with data analysis for Excel and CSV files. Every exercise is based on genuine tasks from your own function.

The second focus is scale and responsibility. You build a custom GPT that knows your templates, tone of voice and review rules, and that colleagues across the workspace can use. We also clarify which data belongs in ChatGPT and which does not, how Team and Enterprise workspaces differ from personal accounts, and which settings matter for model training, memory and sharing. You leave with a personal prompt library, a working GPT and clear ground rules for using ChatGPT responsibly across your organisation.

Tax advisory firms are under pressure from staff shortages, rising client expectations and a constant stream of legislative changes, administrative guidance and court rulings. Used responsibly, generative AI can provide real relief. AI assistants summarise case law and tax authority guidance, structure facts from client documents, draft client newsletters and objection letters and answer routine questions in plain language. Automation supports document intake, deadline management and client communication. Professional judgement and liability remain with qualified tax advisers, but research and drafting become faster. The key prerequisite is safe handling of client data: professional secrecy, professional conduct rules and the GDPR determine which tools may be used and how.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.

Practical scenarios from your field

Summarising case law

An AI assistant summarises rulings, tax authority guidance or draft legislation, highlights key points and affected client groups and drafts internal technical updates that qualified advisers then check against the original source.

Drafting objections and submissions

Based on anonymised facts, AI produces a structured draft of an objection, a request to suspend enforcement or a reply to the tax office, including an outline of the arguments for further professional work.

Client communication

AI drafts clear client newsletters, explanations of tax assessments and reminders about missing documents, adapted for private clients, freelancers or businesses.

Document checklists

For income tax returns, annual financial statements or payroll queries, AI creates tailored checklists based on the client profile, reducing follow-up questions and repeated requests.

Automated document intake

An automation sorts incoming client documents, recognises document types, applies consistent file names and passes them to the practice software or flags missing information.

Knowledge management

Internal guidance notes, review templates and model wording are prepared and made searchable with AI support, so staff can access proven practice know-how more quickly.

Prerequisites

Confident use of office applications and a web browser; no prior AI knowledge is required. Feel free to bring your own non-confidential sample tasks from your daily work. You work in a tax practice or corporate tax department and have a basic grounding in tax law.

Technical requirements

A laptop with an up-to-date browser and a ChatGPT account; a paid plan or access to your organisation's Team or Enterprise workspace is recommended for custom GPTs, Projects and data analysis.

Data protection & compliance

German tax advisers are bound by professional secrecy under the Tax Advisers Act and Section 203 of the Criminal Code; client data may only be shared with AI providers contractually bound to confidentiality and processing data in line with the GDPR. Otherwise, facts must be consistently anonymised.

Frequently asked questions

Do I need a paid ChatGPT licence for the course?

You can follow the fundamentals with a free account. However, features such as custom GPTs, Projects with larger files and advanced data analysis are tied to paid plans or come with far more generous limits there. Ideally you join with access to your organisation's Team or Enterprise workspace, so you practise under real conditions.

May I enter confidential company data into ChatGPT?

That depends on your plan, your contractual terms and your internal policy. In Team and Enterprise workspaces, content is not used for training by default, but GDPR and confidentiality obligations still apply. In the course you learn how to classify and anonymise data and how to choose the right settings.

How is a custom GPT different from a saved prompt?

A GPT bundles persistent instructions, knowledge files and optional tools such as web search or data analysis into a dedicated assistant. Colleagues can use it without any prompting skills and get consistent results. A saved prompt, by contrast, has to be copied and supplemented with context every time, which is far more error-prone.

May client data be entered into AI tools?

Only under strict conditions: the provider must be bound to confidentiality as a service provider, data processing must be contractually GDPR-compliant and inputs must not be used for training. Otherwise, work with anonymised facts. In the course we develop practical rules tailored to your practice.

Can AI give binding answers to tax questions?

No. AI assistants can be wrong about provisions, deadlines or case law and may not know the latest changes. They are useful for structuring, first drafts and research pointers. Professional judgement and liability stay with qualified advisers, who check every statement against legislation, commentaries and case law.

How much does “ChatGPT for Tax Advisers” cost?

The course costs a flat €949 plus VAT per participant – whether online or on-site. This includes 1 training day(s) with a live trainer, course materials, a lab environment and a certificate of attendance.

Can I suggest my own date?

Yes. Our suggested dates are just a guide. In the request form you can always describe your preferred date or period in free text – we check availability and confirm within one working day.

Is the course online or on-site?

Both are possible: live online in a virtual classroom or on-site in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart or Kaiserslautern. We can also run the course exclusively for your team.
