1. The 50p tax rate is being reduced to 45p as HMRC has determined it is not raising as much revenue as initially expected due to taxpayers shifting income to avoid the higher rate.
2. Starting in April 2013, HMRC is implementing real time reporting of payroll information from employers on a more frequent basis instead of just at the end of the tax year to improve tax collection.
3. Changes to pension tax relief are ongoing, including a reduction of the annual allowance from £50,000 to £40,000 starting in 2014-15, and a decrease in the lifetime allowance to £1.25 million, which will impact more individuals and require reconsideration of retirement planning.
