Berlin Pushes Card Payments to Combat Tax Evasion

Berlin is moving to dismantle the “cash only” culture that has long defined its eclectic landscape of kiosks, cafes, and barbershops. In a significant push for financial modernization, the city’s governing coalition is spearheading an initiative to mandate that all businesses and restaurants offer at least one form of digital payment, effectively targeting the systemic use of cash to facilitate tax evasion.

The proposal, driven by the CDU and SPD factions in the Berlin House of Representatives, seeks to complete the practice where vendors exclusively accept banknotes. This move is not merely about consumer convenience; it is a strategic effort to close loopholes that allow businesses to underreport earnings. By requiring a digital trail for transactions, the city aims to combat “steuertricks”—tax tricks—and the prevalence of undeclared work in cash-intensive sectors.

At the heart of this initiative is the belief that the insistence on cash-only payments is often a veil for financial misconduct. According to Dirk Stettner, the CDU faction leader and a hotelier himself, there is little justification for refusing digital payments other than a desire to avoid tax obligations. The financial stakes are high, with estimates suggesting that the German treasury loses between 15 to 20 billion euros annually due to cash-related register fraud.

The Legislative Push: From Berlin to the Bundesrat

Because the city cannot unilaterally change national commercial laws, the Berlin coalition is preparing a Bundesrat initiative. The goal is to persuade a majority of German states to urge the federal government to amend the Civil Code (Bürgerliches Gesetzbuch) or the Trade Regulation Act (Gewerbeordnung) to include a legal mandate for digital payment acceptance .

The timing of this push is critical. Faction leaders Dirk Stettner and Raed Saleh are urging the Senate to move forward with this initiative before the Berlin elections scheduled for September. They have found a key ally in Finance Senator Stefan Evers (CDU), who supports the move as a step toward greater “tax justice.”

The initiative specifically targets high-cash industries, including “Späti” convenience stores, Döner stands, and barber shops. In these sectors, the state estimates that between ten to 15 billion euros in sales and profit taxes are lost annually, with additional losses occurring in unpaid wage taxes and social security contributions when employees are paid “under the table” .

Who Will Be Affected?

While the objective is broad, the coalition acknowledges that a blanket mandate would require nuanced exceptions. The proposed framework suggests that the obligation to provide digital payment options would not apply in the following circumstances:

• Locations where the necessary technical infrastructure is permanently missing.
• Unmanned points of sale.
• Micro-businesses that can prove a specific hardship case.

Crucially, Dirk Stettner has emphasized that this initiative is not intended to abolish or restrict the use of cash. Rather, it is about ensuring that digital payment is an available option for the consumer, ensuring a fairer competitive environment where honest businesses are not undercut by those avoiding taxes.

Consumer Rights and the Digital Transition

For travelers and residents in Berlin, the transition toward digital payments has been gradual but uneven. While major retailers and hotels widely accept cards, smaller establishments have historically clung to “Cash Only” signs. Current laws already prohibit merchants from charging additional surcharges for using cards or mobile payment methods, but the legal obligation to offer those methods has been absent until now .

From a global perspective, this shift aligns Berlin with other major metropolitan hubs that have transitioned to “cash-lite” economies. For international visitors, the move would reduce the reliance on ATMs and the friction of carrying large amounts of currency. However, the acceptance of specific card brands can still vary; for instance, while Visa is widely accepted, some businesses in Berlin have been reported to reject American Express .

Economic Implications of the “Digital Mandate”

The shift toward mandatory digital payments has two primary economic drivers: consumer psychology and fiscal enforcement.

1. Fiscal Enforcement: The primary driver is the reduction of the “shadow economy.” Digital transactions create an immutable audit trail, making it significantly harder for business owners to hide revenue from the tax authorities. When a transaction is recorded digitally, it is much more difficult to omit from the end-of-day accounting.

2. Consumer Behavior: Digital payments generally lower the barrier to purchase. Consumers are more likely to spend when they are not limited by the physical cash in their wallets. By forcing “cash-only” shops to modernize, the city may see a marginal increase in transaction volumes in the small-business sector.

What Happens Next?

The next critical step in this process is the April faction retreat (Fraktionsklausur) with the Senate, where the topic of the Bundesrat initiative has been officially placed on the agenda. The coalition’s success depends on securing a majority of the German states to support the move, as the legal changes required must occur at the federal level.

If successful, this could signal a permanent shift in the commercial landscape of Germany’s capital, moving it away from the traditional “cash is king” mentality toward a more transparent, digitally integrated economy. The city hopes to have this framework in motion before the September elections.
