Robotic Process Automation is revolutionising tax advisory: which processes can be automated, which tools are ready for practice, and where does the human element remain indispensable?
When Software Robots Take Over Routine Work
The tax advisory sector is facing fundamental change. While client numbers are growing and tax law requirements are becoming ever more complex, the shortage of skilled professionals is intensifying. In this situation, Robotic Process Automation (RPA) promises relief that goes beyond conventional digitalisation: software robots that handle rule-based routine tasks, freeing qualified staff for substantive advisory work.
But what can RPA actually deliver in tax advisory? Which processes are suitable for automation, and where are the limits? In this article, we provide a practice-oriented overview of use cases, available tools and the professional regulatory framework.
What Is Robotic Process Automation?
RPA refers to the use of software robots (known as bots) that mimic human interactions with IT systems. Unlike conventional process automation, RPA bots operate on the user interface of existing applications. They click, type, copy and paste as if a person were sitting at the computer. The decisive advantage is that existing systems do not need to be modified or connected through interfaces.
For tax advisory, this means that processes previously carried out manually between various programmes such as DATEV, Excel, ELSTER and email applications can be performed by bots without fundamentally restructuring the firm's IT infrastructure.
Which Processes Can Be Automated?
Data Entry and Document Processing
The biggest time drain in many firms is the manual capture of receipts and their allocation to accounting categories. RPA bots can extract invoice data from PDF documents, reconcile them with master data and transfer them to accounting software. Combined with Optical Character Recognition (OCR) and machine learning, the results improve continuously. The DATEV Automation Services for Accounting already use AI-based posting suggestions that learn from every correction made by the user.
Account Reconciliation and Plausibility Checks
The regular reconciliation of bank accounts, accounts receivable and accounts payable with posted values is a classic RPA candidate. Bots can systematically identify discrepancies, generate difference lists and present only the genuinely problematic cases to the specialist. This not only saves time but also enhances audit quality.
VAT Returns and Reporting
The preparation of VAT returns (Umsatzsteuer-Voranmeldungen), recapitulative statements and other reporting obligations follows clear rules. RPA bots can compile the relevant data from the accounting system, transfer it to the ELSTER forms and prepare the submission. Final approval remains with the tax adviser, yet the manual effort is reduced by up to 80 per cent.
Client Communication and Deadline Management
Automated reminders for missing documents, systematic monitoring of tax deadlines and documentation of client contacts in the practice management software can all be efficiently handled with RPA. This reduces the risk of missed deadlines, which under § 46 of the German Tax Advisory Act (Steuerberatungsgesetz, StBerG) can lead to professional consequences.
Reporting and Analysis
Management reports (betriebswirtschaftliche Auswertungen, BWA), sector comparisons and individual client reports often require consolidating data from multiple sources. RPA bots can handle this data aggregation and produce standardised reports, which the tax adviser then supplements with professional assessment.
Overview of Tools and Platforms
UiPath
UiPath is one of the world's leading providers of RPA solutions. The platform offers a visual workflow designer that can be used without programming skills. For tax advisory firms, UiPath is particularly interesting through its combination with AI modules enabling intelligent document processing. Specialist providers such as Robotics First use UiPath as the foundation for DATEV-specific automation solutions.
Automation Anywhere
Automation Anywhere takes a cloud-first approach and delivers its bots as software-as-a-service. The platform is particularly suitable for firms that do not wish to operate their own server infrastructure for RPA bots. Integration with common office applications is mature, and scaling individual automations is straightforward.
DATEV-Specific Solutions
DATEV itself is consistently advancing the automation of its products. The DATEV Automation Services for accounting generate AI-based posting suggestions from digital incoming and outgoing invoices. Additionally, third-party providers such as robobee and Ebner Stolz offer specialised RPA tools for tax advisory professionals.
ROI Analysis: Is the Investment Worthwhile?
The costs of implementing RPA vary considerably. For a single process automation, typical licence costs range from 5,000 to 15,000 euros per year, plus one-off implementation costs. Against this stands significant savings potential: a Deloitte study shows that RPA in tax advisory can increase productivity by up to 85 per cent, reduce error rates by 90 per cent and cut costs by up to 59 per cent.
For a mid-sized firm with 10 to 20 employees, the investment typically pays for itself within 6 to 18 months. The key is selecting the right processes: high volumes, clear rules and low exception density are the best prerequisites for rapid payback.
Professional Regulatory Framework
Independent Professional Practice Under the StBerG
The German Tax Advisory Act (Steuerberatungsgesetz, StBerG) requires tax advisers to exercise their profession independently, conscientiously and in confidence. The Federal Chamber of Tax Advisers (Bundessteuerberaterkammer, BStBK) has clarified that the use of technical aids is generally permissible provided the personal responsibility of the professional is maintained. This means: automation is not a substitute for professional practice. The tax adviser must review, evaluate and take responsibility for automatically generated results.
Data Protection and Confidentiality
Particular caution is required when using cloud-based RPA solutions. Client data is subject to professional secrecy under § 57 para. 1 StBerG and the requirements of the GDPR. Processing in cloud environments requires careful examination of data processing agreements and, where applicable, a data protection impact assessment. Solutions that process client data exclusively in German or European data centres are preferable.
Quality Control as a Duty
The professional code of conduct for tax advisers requires appropriate quality assurance measures. When using RPA, this means: regular checking of bot results, documented sample audits and a defined escalation procedure for errors. The BStBK recommends in its FAQ on AI in the Tax Advisory Profession a structured approach to automated processes that always ensures human oversight.
Limitations: What RPA Cannot Do
As powerful as RPA is for rule-based tasks, its limitations become clear with complex matters. The following areas continue to require the tax adviser's expertise:
- Tax structuring: Developing optimal tax structures requires creativity, experience and a holistic view of the client's situation.
- Legal assessment: Classifying ambiguous facts and arguing before the tax authorities are genuine advisory services.
- Client relationships: Trust, empathy and understanding of the overall entrepreneurial situation cannot be automated.
- Exceptional situations: When the facts deviate from the rule, the bot reaches its limits — and that is precisely where the adviser's value creation begins.
The Changing Role of the Tax Adviser
RPA does not change the profession, but the activity. Tax advisers will spend less time on data entry and routine work and more time on what their clients value most: well-founded advice, strategic tax planning and personal attention. The firm of the future is a hybrid organisation in which humans and machines each play to their respective strengths.
Practical Tips for Getting Started
- Conduct a process audit: Identify the most time-intensive routine processes in your firm. Document every step and ask: is this step rule-based and repeatable?
- Start small: Begin with a single process, such as automated bank posting imports. Gain experience before scaling.
- Involve employees: RPA is not a headcount reduction programme. Communicate openly that automation is intended to relieve staff, not replace them.
- Establish quality assurance: Define control mechanisms, sampling rates and escalation paths from the outset.
- Observe professional regulations: Ensure that the personal responsibility of the professional is preserved in every automated process.
Conclusion
Robotic Process Automation is no longer a future topic but a living reality in progressive tax advisory firms. The technology offers significant potential for efficiency gains, error reduction and staff relief. At the same time, the tax adviser remains irreplaceable in their professional responsibility. The key lies in the right balance: automate what can be automated and invest the time gained in high-quality advisory work.
