The accountancy firm also predicts the chancellor, Alistair Darling, will introduce a new lower rate of employers' National Insurance Contributions at 5% for staff earning up to £20,000 from 2011 and a new higher rate of 17.5% for those earning over £40,000 from 2012.
Currently employers pay a flat rate of 12.8% regardless of how much employees earn but reducing the rate for those earning less will be politically attractive for the Labour Party, according to MacIntyre Hudson.
The firm also believes the Government will impose heavier taxes on high earners while offering relief to pensioners.
Nigel May, tax principal at the firm, said: "The chancellor has already indicated he will seek to help pensioners, who often depend on the income from modest savings to supplement their pensions, and who have suffered most from the reduction of interest rates. The most effective way to achieve this would be to exempt the first £5,000 of pensioners investment income from income tax.
"The current political mood allows the chancellor to recover significant revenue by increasing taxes on the investment income of the better off. There won't be many backbenchers weeping for the bankers on this one."
