This is somewhere between deeply irresponsible and a lie.
HMRC will be able to "seize money" from people who owe tax, aren't disputing it, but just fail to pay. That's people who cause the rest of us to pay more tax.
Under Labour, HMRC will reach into your bank account and seize your money.
Under Reform, you’ll get a £30 rebate if HMRC leave you stuck on the phone for 30 mins.
