New rules have come into force this week which mean advisers assisting clients with tax evasion will face fines.
The crackdown means accountants, bankers, solicitors and financial advisers could be fined up to 100% of the amount of tax they helped evade, up to a maximum of £3,000.
They will also be named and shamed, in order to discourage tax evasion, as part of the new powers which were announced in the 2015 Budget.
No reputable financial adviser would assist a client with tax evasion, which is illegal.
Even advice on entirely legitimate tax avoidance measures is now treated with care, with government rhetoric on legal avoidance discouraging advisers and taxpayers from pursuing these measures.
"The raft of measures we have introduced to tackle avoidance and evasion will create a level playing field for the vast majority of people and businesses who play fair and pay what is due."
