As in - should they change the rules so you can pay for childcare from your gross salary, rather than after tax. The childcare vouchers schemes work like that, but the amounts you can take are ridiculously low (less than £150 per month under the new rules).
Most childcare providers will then pay tax themselves on the payments they receive, so there's taxation in the cascade - it just helps working parents pay for their children's care more easily.
What do you think?
