I I copied this directly from a bulletin I received from Revolut and I thought this was worth copying you in on. Scams are always harder to spot when they appear to be coming from a place of authority. Here's what Revolut said and I hope it helps to keep you safe:

It’s tax season, 
'Tis the season to be extra wary

We know nothing gets you excited like all the fun admin of tax season.

But if you think you're excited, it's nothing compared to scammers and fraudsters. This is their Christmas and they come bearing a new way to get their mitts on your money.

So, what's the scam?
Scammers and fraudsters will call you claiming to be HMRC. They'll offer you a rebate once you pay a fee, or by pretending you have to urgently pay a fine or you’ll be arrested.

To make it worse, these criminals can also change their phone numbers to make it look like you’re getting a genuine call from HMRC. They may even ask you to check the number online to validate it and build your trust.

If they call, what should I do?
HMRC will never contact you over the phone demanding payment at the risk of consequences or ask you to make a payment in return for a larger rebate afterwards.

If you’re contacted by someone claiming to be from HMRC or the Police, hang up and contact them independently via the contact numbers listed on their official website.

Here's a few bonus tips on avoiding scams this tax season
Stop and contact us via the in-app chat before you proceed with making any payments to a new beneficiary
UK Government banking account sort codes are 08-32-XX - If the payment you’re making isn’t to this Sort Code, it's highly likely it's a scam
HMRC and other tax authorities will never contact you over the phone demanding payment
HMRC and other tax authorities will never ask you to pay anyone else, like a solicitor or agent
HMRC and other tax authorities will never tell you which buttons to press or ask you to download software to allow someone else to view your screen or tell you to ignore payment warnings
If any of the above is happening to you, it’s likely you’re being scammed and we may not be able to recover your money if it leaves your account.

So please stop and contact us via the in-app chat before you proceed with making any payments to a new beneficiary.

All the best.
