“If you have payments due now or in the near future the sooner you get in touch the sooner HMRC can begin working with you to find a solution. They may….allow you time to pay. If your payment isn’t due yet you can call the support service nearer the time ….But remember that you need to get in touch in HMRC in advance of the payment deadline date. Don’t wait until the payment is overdue.”

(4) …. if a taxable person on whom a surcharge liability notice has been served— (a) is in default in respect of a prescribed accounting period ending within the surcharge period specified in (or extended by) that notice, and (b) has outstanding VAT for that prescribed accounting period, he shall be liable to a surcharge equal to whichever is the greater of the following, namely, the specified percentage of his outstanding VAT for that prescribed accounting period and£30 .”
