Credit Card Campaign | GSC Consultancy Tax

What Is the Credit Card Campaign?

HMRC's Credit Card Campaign is an enforcement initiative that uses data obtained from credit card companies and payment processors to identify businesses and individuals who may not be declaring their full income for tax purposes.

HMRC can obtain records of credit and debit card transactions processed by businesses. By comparing this transaction data with declared turnover on tax returns, HMRC can quickly identify significant discrepancies that suggest undeclared income.

How Does HMRC Obtain the Data?

Under information-gathering powers in Schedule 36 of the Finance Act 2008, HMRC can issue notices to card processing companies requiring them to provide detailed transaction data. This includes:

Total value of card payments received by each merchant
Number of transactions processed
Merchant name and identifying details
Bank account details linked to the merchant account

HMRC then cross-references this information against the tax returns filed by the businesses concerned.

Who Is Affected?

Any business that accepts card payments could potentially be affected. Sectors that have been particularly targeted include:

Retail businesses — both high street and online
Restaurants, takeaways, and cafés
Hotels, B&Bs, and hospitality businesses
Tradespeople and service providers
Online sellers and marketplace traders

What Should You Do?

If your card transaction records show higher receipts than the income declared on your tax returns, HMRC is likely to open an enquiry. Before that happens, consider:

Review your records: Compare your declared income with your actual card transaction records
Make a voluntary disclosure: Use the Digital Disclosure Service or contact HMRC directly to disclose any under-reported income
Seek professional advice: A specialist tax adviser can help you assess your position and manage the disclosure process

Consequences of Non-Disclosure

Failing to act when you know your returns are inaccurate can lead to:

Substantial penalties — up to 100% of the tax due
Interest on late-paid tax
Potential criminal investigation in the most serious cases
Public naming and shaming for deliberate tax defaulters
