The Netherlands’ contribution to the EU may rise 62.5% over the next few years, the Financieele Dagblad said on Tuesday.

Sources have told the paper that if the European Commission manages to get its new spending plans approved, the annual Dutch contribution will soar to €13bn by 2027. Next year, the Dutch contribution is €8bn.

The paper says ministers consider the increase to be unacceptable, partly because a large part of the increase will come from scrapping the current €1.5bn discount given to the Netherlands. Brussels is planning to end the system of giving net payers a discount on their gross contribution.

Figures from national statistics agency CBS show the Netherlands contributes more per head of the population to the EU coffers than any other country, although Germany is the biggest net payer, with a 2020 contribution of €15bn. That is set to rise to €33bn by 2027, the FD said.

The Netherlands and Germany said in a joint statement earlier this month that they wish to keep to the current 1% platform in the new budget which would fix total EU spending to 1% of Europe’s gdp. The new commission wants to bump this up to 1.11%.

The situation is being made worse by Brexit, which will leave the remaining EU members with a €13bn annual shortfall to make up.

The national audit office said in January that when Britain leaves the EU, the Netherlands will have to pay an extra €1.25bn in 2021 to shore up the EU budget.
