Staying in the same public sector contract after April 2017

[TheFaQQer]

And look at payontime for details of charging the b*st*rds interest for late payment!

At the moment, I wouldn't be pushing for payment - because if they pay having deducted tax and NI then you won't be able to get that back.

My approach would be to sort out the appeal, get the agreement that there shouldn't be any tax deducted, then get the invoice paid.

(Then add interest for late payment once it's all sorted )
