The Low Income Tax Reform Group is urging taxpayers, including umbrella company contractors, to double check calculations if they receive letters from HMRC.
Accountants claim that HMRC is adopting threatening behaviour towards innocent tax payers and umbrella company contractors in a bid to gather in more income.
The BBC was recently told by HMRC whistleblowers that the Revenue has been instructed not to chase a lot of underpayment cases that are over two years old and which could be open to a legal challenge; a claim that has been strongly denied by an HMRC spokesman.
The Low Income Tax Reform Group believes that HMRC’s decision to reduce the opening hours of its helpline will hamper it in its long term aim to move to online services.
