Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether people paid monthly for whom April was treated as month one prior to the introduction of Real Time Information (RTI), but for whom May would then be treated as month one after the introduction of RTI were overtaxed as a result of missing out on one month of tax-free pay at the point at which RTI was introduced.

The introduction of RTI did not result in changes to the tax calendar. The first payment made on or after the 6^th April is classed as month 1 and this did not change post RTI. No individuals should have been overtaxed as a result of the implementation.
