Income tax cuts expected, toward government aim of 20p basic rate. Clarke's options are to reduce the basic rate by 1p, 2p or even 3p in the pound; increase allowances by more than the rate of inflation; increase tax thresholds by more than the rate of inflation; widen the lower rate 20p band.
Profit-related pay suggested as a likely candidate for abolition. Tax relief for about 3 million employees in PRP schemes costs close to pounds 1bn. Restricting the tax relief might be more palatable
Government spending planned for hospitals and schools is likely to rise. Roads programme is expected to suffer. Clarke will have to reduce the public spending "control total" by pounds 1bn-3bn. Lower inflation means there can be cuts without any reduction in real spending. Watch or an announcement about social security fraud.
Single parent benefit might fall victim to the pro-family lobby on the Conservative back benches even though the money can make a huge difference to recipients.
Alcopops a swingeing increase in excise duty likely. Accounts for less than 2 per cent by volume of the alcoholic drinks market. Strongly criticised for being aimed at young people. Brewers would like to see a cut in duty on beer to fight back against Cross-Channel shopping and smuggling.
MAKING BUSINESS PAY
The Government likes to encourage small businesses. A reduction in the rate of corporation tax by 1 or 2 per cent is a possibility. The reintroduction of first year capital allowances is an outside chance. Expect further snips at red tape.
Insurance premium tax introduced by Clarke in 1994. Insurers fear an increase this year.
Gaming duties might fall, to help pools and betting companies compete with the National Lottery.
Clarke might have some wheeze for extra taxes on privatised electricity, water and gas companies to undermine Labour's plans for a windfall tax.
Clarke will probably try to close tax loopholes when it comes to corporate taxation too.
Current rates are 20% up to pounds 3,900, 24% up to pounds 25,500, and 40%. Allowances: personal pounds 3,765; married couple pounds 1,790 (higher for older couples); aged 65-74, pounds 4,910; over 75, pounds 5,090

These companies would face paying some pounds 5bn-10bn under Labour
After the puzzle about unexpectedly low corporate VAT payments last year, he could tighten rules
KEEPING THE VOTERS SWEET
Petrol duty should rise by 5 per cent more than inflation, adding 3p a litre. Norman Lamont introduced the principle that duties on road fuel should increase in real terms every year. Tobacco duties will increase by 3 per cent on top of inflation, adding about 12p to a packet of 20 cigarettes.
John Major promised to abolish capital gains tax and inheritance tax so that wealth could "cascade down" the generations. But Clarke is unlikely to deliver. Abolishing capital gains tax would give a huge boost to the tax avoidance industry while abolishing inheritance tax would benefit fewer than 25,000 voters
The Chancellor might decide to do more to encourage savings by making Peps and Tessas even more attractive or augment the enterprise investment scheme.
Redundancy pay might lose its tax exemption, saving the Treasury pounds 1.5bn
The Chancellor will try to close tax loopholes. Will probably, as usual, extend national insurance to the ever more esoteric means that companies use to pay bonuses to high earners
VAT is not expected to be raised or extended. Clarke is vulnerable to Labour attacks over its record of raising VAT.
PLEASING THE MARKETS
Clarke's forecast for growth next year now looks quite cautious so he may raise it a little. This would make the outlook for government borrowing look better, would have to edge up the inflation forecast.
Privatisation proceeds are a handy source of money to finance tax cuts. Mr Clarke may announce new asset sales.
