Over the past decade, the relationship between electronic payments and tax evasion has become one of the most debated issues in economic policy. The underlying principle is straightforward: every transaction made by card, smartphone or other digital payment method leaves an electronic record, making it more difficult to conceal revenue.
However, economists and international institutions broadly agree on one point: POS terminals alone do not eliminate tax evasion. Rather, they represent one component of a broader strategy that includes electronic invoicing, tax administration digitalisation and automated compliance controls.

Italy: the new link between POS terminals and fiscal receipts
Italy has recently become one of Europe’s most closely watched case studies. Since 1° January 2026, businesses have been required to align POS terminals with electronic cash registers, allowing the Italian Revenue Agency to compare electronic payments with issued fiscal receipts more efficiently.
According to figures reported by major Italian financial newspapers and summarised by the Italian daily Quotidiano Nazionale, the new system identified approximately euro 9.1 billion in additional taxable transactions during the first half of 2026, potentially generating around euro 1.6 billion in additional VAT revenue, alongside further income tax receipts.
These figures do not necessarily demonstrate that all of those transactions represented tax evasion. They do, however, illustrate how cross-checking electronic payments with fiscal documentation can significantly improve transparency and tax compliance.
Europe: where the VAT gap has narrowed
Each year, the European Union measures the VAT Gap, which represents the difference between the VAT theoretically owed and the amount actually collected.
Over recent years, many Member States have successfully reduced this gap by combining several measures:
- electronic invoicing
- digital payment systems
- automated data matching across tax databases
- risk-based compliance controls
Among the countries showing the most significant improvements are Portugal, Greece and Italy, all of which have introduced increasingly sophisticated digital tax administration tools designed to improve transparency and voluntary compliance.
European institutions nevertheless emphasise that these results stem from the combined effect of multiple reforms rather than from electronic payments alone.
International success stories
Several governments have adopted different strategies to encourage digital payments and improve tax collection. South Korea remains one of the world’s most frequently cited examples. Since the late 1990s, consumers have benefited from tax deductions when paying by card, contributing to a substantial increase in electronic transactions and greater reporting of taxable income.
India experienced a rapid expansion of digital payments following the 2016 demonetisation policy. Today, the country’s Unified Payments Interface (UPI) has become one of the largest instant payment systems in the world.
Portugal and Slovakia have experimented with tax receipt incentive schemes, while Greece introduced mandatory electronic spending thresholds for taxpayers wishing to qualify for certain tax benefits.
Meanwhile, Sweden has become one of the world’s closest examples of a cashless society, although public debate continues regarding the importance of preserving cash for resilience and emergency situations.
G7 and BRICS: different approaches to the same challenge
Among G7 economies, electronic payments are already widely used, yet governments employ different strategies to combat tax evasion.
In the United States, tax enforcement relies heavily on information reporting and cross-checking financial data rather than on strict limits to cash usage.
France and Germany continue expanding the digitalisation of their tax administrations while encouraging greater use of electronic payment methods.
Japan has accelerated digital payment adoption in recent years as part of its broader economic modernisation strategy.
Within the BRICS group, China stands out as perhaps the world’s most advanced digital payment ecosystem. Platforms such as Alipay and WeChat Pay process enormous volumes of daily transactions, generating valuable economic data for tax authorities.
Brazil and India have also transformed domestic payment systems through real-time digital payment platforms that are reshaping consumer behaviour and improving transaction traceability.
Can electronic payments alone reduce tax evasion?
The available evidence suggests that there is no single solution capable of eliminating tax evasion.
Most international organisations identify several complementary tools as essential:
- transaction traceability
- electronic invoicing
- integrated tax databases
- digital tax filing systems
- automated compliance controls
- simplified tax procedures
- incentives for voluntary compliance
Electronic payments therefore represent an important policy instrument, but their effectiveness increases significantly when combined with a fully digital tax administration.
The future lies in digital tax administration
International experience demonstrates that reducing tax evasion depends on far more than replacing cash with electronic payments. The strongest results are generally observed in countries that have built integrated digital ecosystems connecting payment systems, fiscal documents, tax databases and automated auditing tools.
Italy’s new integration between POS terminals and electronic cash registers marks another step in this direction. Whether the reform will produce a lasting reduction in the country’s tax gap will become clearer as additional data become available over the coming years.
