Tax & Finance Operations Intern (m/w/d) - Startup

We are building Germany's leading Tax Advisory firm. Taxforce was founded based on a simple observation: Many business owners want a tax advisor who acts as a true sparring partner: proactive, responsive, and strategic. What they often get instead is a service provider: booking receipts and filing tax returns, with little real advisory.

We’re building the alternative.

Founded in 2025, Taxforce rethinks tax advisory from the ground up: AI-powered and highly automated, yet personal. We’re starting with healthcare professionals, a complex and underserved segment, with the ambition to expand into many more industries over time.

Instead of pure compliance, we deliver real advisory and become long-term partners to our clients: from initial setup to established organizations.

This is a €40B market in Germany alone, with processes that have barely changed in decades. AI is now enabling a fundamental shift and there are no playbooks yet. We’re writing them.

We’re a small, highly ambitious team in Berlin, backed by €5M from Tenet VC and founded by alumni of Goldman Sachs, Harvard Business School, Bain & Company and the former Klarna Head of Engineering. You’ll work directly with the founders, take on real responsibility from day one, and see how AI transforms a real-world industry.

We offer a high-ownership environment, direct feedback and mentoring, a collaborative team, and competitive salary all from our office near Boxhagener Platz.

Join early and help us redefine tax advisory.

Tasks

As a Tax & Finance Intern, you'll work right in the middle of our operational and advisory tax work. You'll take on responsibility from day one, both externally, supporting our tax advisors, and internally, in our own controlling and bookkeeping along the entire value chain: from preparing client tax returns and hands-on research, to managing invoicing, funds, and cashflow, through our monthly internal financial close. Because tech and tax work together at Taxforce, you'll be close to the point where manual work turns into automation and you'll actively help us make our processes better:

Support the monthly internal bookkeeping and financial close

Build and maintain reporting and controlling analyses over time

Tax Operations
