British Authorities Seek Data from Crypto Exchanges in Search of Tax Evaders

HM Revenue & Customs, the British tax authority, is pressuring cryptocurrency exchanges to reveal customers’ names and transaction histories, in a bid to claw back unpaid taxes, industry sources said.

Letters requesting lists of customers and transaction data have landed on the doorsteps of at least three exchanges doing business in the U.K. – Coinbase, eToro and CEX.IO – in the last week or so, the sources said. None of the three firms would comment by press time.

“HMRC is looking to work with exchanges when it comes to finding information on people who have been buying and selling crypto. I think they will only go back a couple of years, two or three years,” said one industry insider.

The source pointed out that it would be very difficult to provide ten years’ worth of information for any platform, adding:

“If they [HMRC] do only go back two or three years, I think the interesting thing here is, that the individuals who went into crypto very early on in 2012-13 will not be affected. The ones who probably made the largest gains won’t be affected, it will be the people who came in around the time crypto peaked.”

In response to a Freedom of Information (FOI) Request submitted by CoinDesk, HMRC said it was withholding details about its demands for information since disclosing them could jeopardize the assessment or collection of tax.

But the agency confirmed such demands are within its remit, saying:

“These exchanges can retain information on their clients and the transactions that they have completed. These transactions may result in potential tax charges and HMRC has the power to issue notices requiring exchanges to provide this information.”

HMRC’s move is following a pattern set by the U.S. Internal Revenue Service (IRS) and other governments.

Last month, the IRS began sending warning letters to over 10,000 Americans who it says participated in virtual currency transactions but did not report them properly.

In the past, Coinbase has fought against what is known as a “John Doe” summons; an attempt by government agencies to gather hitherto unknown customer information, including taxpayer ID, name, birth date, address, and historical transaction records.

In December 2016, the Internal Revenue Service issued the summons demanding that Coinbase produce a wide range of records relating to approximately 500,000 exchange customers. In a partial victory for the company, a court order compelled it to produce records for only 13,000.
