You pay National Insurance contributions to qualify for certain benefits including the State Pension.

• 16 or over

The Office of Tax Simplification is currently beginning a process of looking at merging National Insurance with Income Tax.

ACCA’s head of tax Chas Roy-Chowdhury warned that an alignment of NI and income tax rates would be crucial prior to a merger taking place.

Middle and high earners could see their tax bills jump under radical plans to merge income tax and National Insurance, a tax expert has warned.

People taking home £50,000 a year could be £230 worse off, but low earners on £20,000 would save more than £530, and those on £30,000 would come out around £380 ahead, according to snap research by Tilney Bestinvest on the potential tax shake-up.

Chancellor George Osborne wants to reduce ‘complexity’ in the tax system to make it clearer exactly how much people have to cough up, and has ordered the Office of Tax Simplification to see if there is a case for change.

The government has already announced a consultation on the pension tax relief system, and I believe that a merger of income tax and NI would likely result in the floated idea of a pension with ISA-like tax treatment. This is because at present, a basic rate taxpayer gets 20% tax relief on pension payments but surely this would increase to 32% under a combined system. It seems illogical to increase tax relief at a time when they are actually trying to reduce the cost to the Exchequer. An equal tax treatment of ISAs and pensions could be a prelude to merging the two, potentially drawing ISAs into some form of lifetime allowance.
