I got downgraded to 203 ,bought a new car in 2018 so 40% right down left me in a reclaim situation with Revenue- but I returned them far more than 11k--I did reregister to stay on payment--reports say 100k knocked down to 203--Boyd Barrett was on Newstalk saying he was inundated with constituents complaining --taxi drivers in the main !
A simplistic explanation:
Lets say you said you made12 grand profit in 2018
Then claimed 10 grand write down (40%) on a 25 grand vehicle.
As far as welfare is concerned your "pay" was 2 grand for the year
Government seemingly realise this is an issue and are re- considering, currently the solution seems to be getting your accountant to send accounts for this year proving your earnings are higher
