IW Study Shows Germany’s Revenue Transfers Reshape State Budgets

The analysis finds large per‑capita shifts that move money to smaller and eastern states, raising questions about incentives versus solidarity.

Overview

  • An Institute for the German Economy (IW) analysis published on Monday finds that the Finanzkraftausgleich and federal supplements materially change states’ per‑capita revenues compared with a no‑redistribution scenario.
  • Bavaria emerges as the only net loser overall, with the IW estimating an average hit of about €880 per resident from the Umsatzsteuer distribution in 2025.
  • Bremen is the biggest per‑person beneficiary at roughly €2,800 more than in a no‑redistribution model, with Berlin gaining about €1,800 and Thüringen and Sachsen‑Anhalt around €1,600 each.
  • The study estimates roughly €20 billion were redistributed via the Umsatzsteuerverteilung in 2025 and shows the transfers reshuffled state rankings, for example lifting the Saarland several places and dropping Bavaria from near the top.
  • IW economists, led by Björn Kauder, argue the system currently dulls incentives for states to strengthen their own tax base and call for reforms that preserve solidarity while increasing state responsibility, a debate that could affect future state budgets and high‑cost policy choices.
