The 2011 Budget aims to boost business and jobs growth through measures like reducing the corporation tax rate, extending business rate relief, and doubling Entrepreneurs' Relief. It also aims to help families with the rising cost of living by cutting fuel duty and raising the personal income tax allowance. Other measures include changes to inheritance tax, Gift Aid, and introducing passenger duty on private jets. Economic growth forecasts were lowered but borrowing is expected to fall. The Office for Budget Responsibility will become a permanent body advising on budgets.
