The standard rate of Class 1 NIC is now 8%.
Someone working full time, 40 hours pw on minimum wage earning £25,396 pa would pay NIC of £1,026. Someone earning £35,000 would pay £1,394. Someone earning £50,000 would pay £2,994.
Earnings above £967 pw or £50,284 pa are charged at 2%.
Assuming all these people enter the workplace after 5 April 2016 so are not paying into earnings related schemes (Graduated, SERPS, S2P), if they all make the same number of years of contributions, they will all end up with the same amount of single-tier State Pension.
In other words, NIC is just a tax on earnings.
Compare someone who did not work and buys back missing years though Class 3 voluntary contributions. At present this costs £923 per year. Buy back is limited now to 6 years but in the past it was possible to buy back more years. At current rates, every extra contribution year is worth an extra £342 pa in pension. By year four the investment is in profit.
Obviously, buying back years after they have passed means the person isn’t going to be claiming the other contributory benefts that NIC gives entitlement to hence why it’s a little less expensive than for the worker on minimum wage.
Nevertheless, until the single tier pension, the person who didn’t work and paid Class 3 instead is going to get the same SP as the person who did work that year and may have paid a lot more in NIC.
Of the total raised from all kinds of tax, income tax comprises around 28% of the total and NIC 18% including employer contributions. VAT raises about 17%. Other indirect taxes combined raise about 10-12%.
We do all pay taxes but unless someone spends an enormous amount on goods and services, paying indirect taxes only is never going to be equivalent to someone who has had a long working life paying income tax and NIC.
I’d like to see either a flat charge for NIC or see it abolished altogether and incorporated into other taxes, but as it raises around £130 billion a year how would it be done so that everyone expecting what is effectively a flat-rate pension has made an equal contribution?
By 2044, the current surplus in the National Insurance Fund will be exhausted anyway. A scheme that has been self-funding, albeit one generation paying for pensions of the ones before, is no longer going to be.
2024/25 was the first year that expenditure exceeded income. In 2024, Jeremy Hunt cut the NIC rate from 12% to 10% and then 8% resulting in some of the surplus being used to pay contributory benefits.
The surplus is meant to be there as a contingency to meet temporary shortfalls in NIC yield, not to fund regular outgoings.
In 2044, the Treasury is going to have to start putting money into the fund to meet the cost of contributory benefits. We need a radical rethink about how they are funded in the future.
