It seems that the scams are ramping up whilst we're all at home.
I'm receiving BT text messages about unpaid bills (account says theyre paid) and a new one this week, pretty insistent, telling me to phone them as I have been detected for HMRC fraud. If I don't phone them back the police will be at the door...…… I think they got the message when I cut the call after 5 seconds the second time.
Something to be worth being prepared for. For reference HMRC do everything by post and notify by email too. They will ask for reams and reams of paperwork before taking any action, will notify you all the way and then will only take action if you are unwilling or unable to repay their documented shortfall.
Only then are they likely to go to court and you will receive notices many times in writing before it.
Anyone who insists you call back is a scam. Anyone who comes at you out of the blue and says HMRC has made an independent decision without your input is a scam. Anyone who wants you to pay, immediately, by card or by bank transfer is a scam. Even if they have cloned the local HMRC phone number.
