What Will Taxes Look Like in 20 Years?

19.03.2026 |

Twenty years ago, we couldn’t imagine filing a tax return from a mobile phone, that accounting could be handled by AI-powered software, or that most invoices would be automatically linked to the financial administration.

AI Auditor: A Blessing or a Threat?

Artificial intelligence can already read an invoice, fill out a tax return, and find an error faster than the human eye.
In 20 years, AI will be able to:

  • automatically assess all tax risks,

  • predict legislative changes based on trends,

  • and perhaps even estimate what amount of tax a company “should pay to avoid suspicion, but not be too honest either.”

But the question is: will AI also be creative?
Will it seek legal yet advantageous ways to optimize taxes — or will it behave like an average auditor who just ticks the box and goes home?

The Human Advisor: Still Irreplaceable

Even if artificial intelligence can process a tax return in a second, it will never replace empathy, strategy, and human intuition.
Only a person can understand that a client is currently expanding into another country, changing their business structure, or needs advice “on the edge.”

The human tax advisor of the future will be more of a strategic partner – someone who translates the language of algorithms into real business decisions.

Future Legal Developments: Less Paperwork, More Automation

The European Union and Slovakia are already working on projects such as:

  • a unified European digital tax identity,

  • automatic linking of accounting systems with the tax authority,

  • a European tax framework for startups and AI companies,

  • and even the concept of “real-time taxation” – taxes calculated continuously based on real cash flow.

It sounds futuristic, but pilot projects are already underway in several EU countries.
And hopefully, we’ll never live to see the day when the Slovak government introduces a “revolutionary oxygen usage tax.”

A Glimpse into the Future

In 20 years, perhaps:

  • Taxes will be fully automated and continuous.

  • Accounting will be integrated in real time with banks, insurance companies, and partner registries.

  • Every transaction will be automatically classified, taxed, and recorded.

And the tax advisor? They will be more of an AI strategist, helping companies plan for the future — not just survive the next tax return.
