Paul Johnson, the director of the widely-respected independent Institute for Fiscal Studies, has been looking at the latest projections for how much the government will spend in the next five years and how much revenue it will receive. Despite the recent announcement of further cuts in spending, tax rises look difficult to avoid.

Paul explores the reasons for this gap in the budget and asks what taxes could help to fill it. With tax avoidance and evasion now at the top of world leaders' agendas, he asks if the increasingly tax-averse companies sector can be made to pay more and how much the rich and wealthy could contribute. He also considers the taxation of our houses and pensions and whether more will be taken from them.

Then he focuses on the three levies which contribute the lion's share of government revenue - income tax, national insurance and VAT - and, with politicians, economists and tax experts, finds out how much we are all - young and old, better and worse off - likely to pay. He also drops in on a young family in Norfolk to discover what taxpaying voters think of the choices and what they will be expected to pay.

Among those taking part: Nigel Lawson (former Conservative Chancellor of the Exchequer); Kitty Ussher (former Labour Treasury minister); Bill Dodwell (head of tax policy at Deloitte); Julian McCrae (former top Treasury official now at the Institute for Government); Gavin Kelly (chief executive of the Resolution Foundation who worked during the Blair/Brown years in Downing Street and the Treasury); and Malcolm Gammie QC (a leading tax lawyer).
