Here is a guide to the main benefit and tax changes that come into force on 6 April.

Many of the tax and benefit changes which will come into force next month were announced in December's pre-Budget report.

These include the thresholds on employees' National Insurance - now 11% of earnings above £94 a week and 1% of earnings above £630 a week.

The chancellor has increased the thresholds at which taxpayers incur income tax at rates of 10%, 22% and 40% in line with inflation. This will come as a relief to those who feared he would freeze the thresholds and so drag more people into higher-rate tax bands.

	£4,745	£4,895

The chancellor has confirmed that the current £7,000 tax-free savings limit for Individual Savings Accounts (Isas) will be kept until 2010.

The Budget also offered first-time buyers in many parts of the UK a reprieve from stamp duty.

The chancellor increased the starting threshold for stamp duty from £60,000 to £120,000.

Families, who fear that rising property values could boost their inheritance tax (IHT) bill, may benefit from a rise in the inheritance tax threshold.

From 6 April, the first £275,000 of an estate will be exempt from inheritance tax, levied at 40%.

Car drivers were given a pre-election sweetener with another freeze in petrol duty. Vehicle Excise Duty on small and medium-sized cars will also remain the same.

Tax increases on booze and fags were broadly in line with the increases seen in the last Budget.

Pensioners are being offered a £200 council tax rebate, which will be paid in the autumn - but may be a one-off payment.

Pensioners will also receive a £200 winter fuel payment while the over-80s will get £300 - the same as this winter.

Low-income families with childcare needs will receive a significant boost, as an extra £1bn is being given to these families.

Payments for children, under the Child Tax Credit scheme, will rise in line with earnings and over the coming three years by a total of 13%, he said.
