HMRC’s Credit Card Sales campaign targets individuals and businesses that accept credit and debit card payments and have not paid the right amount of tax due. The campaign offers the opportunity for anyone affected to bring their affairs up to date and in doing so take advantage of the best possible terms. Any individual or company that accepts credit and debit card payments should be registered with HMRC. There is currently no end date for this campaign, however, anyone affected should take action to make a disclosure as soon as possible. There are a number of steps involved in taking part in this disclosure opportunity. The first is to notify HMRC that you want to take part in the Credit Card Sales campaign. This can be done by completing and submitting the disclosure form (DO2). Taxpayers must then make a full disclosure about all income, gains, tax and duties within four months from the time a notification acknowledgement is received. This is followed by making a formal offer and payment of tax dues together while fully co-operating with HMRC throughout the process.HMRC’s guidance states that penalties for a full disclosure made as part of the campaign will usually be levied at 0%, 10% or 20% depending on the circumstances. There are higher penalties for offshore liabilities. Taxpayers who are contacted by HMRC before making any disclosure will not have the opportunity to use the terms of this campaign. Penalties of up to 100% of the unpaid liabilities, or up to 200% for offshore related income could then be levied along with the risk of criminal prosecution is serious cases.
