With the self-assessment deadline looming, scammers are ready to target unwitting taxpayers by impersonating HMRC in a variety of ways.
If you are one of the 11.7 million that need to fill out a self-assessment tax return this year, these scams can seem all the more realistic.
In 2019, HMRC received almost 200,000 reports of suspicious phone calls, a huge increase on the roughly 60,000 from 2018.

Fake HMRC phone calls are widespread. There were 195,720 reports of these calls in 2019.

Thanks to technology implemented in April last year, it's impossible for scammers to 'spoof' HMRC's well-known 0300 helpline numbers. Since then, there has been a 94% reduction of phone scams spoofing these numbers.
