I did a roughly 35 hours overtime every month for the past year and just wanted to check to see if it added up correctly so I decided to try the tax refund company. It was fairly straight forward and once completed I heard nothing back for 2 months. Next notification I get is from the gov website and not this company. so I log into my gov gateway and the website said I’ve overpaid approx £40 and that they will be sending payment to the tax refund company. Thinking to myself £40 isn’t to bad and every little helps these days so I was quite pleased. Now I know these company’s don’t work for free so I was expecting them to take something for their troubles. but I did think that being a small amount I wasn’t expecting them to take much. I received a cheque today for £4.77 which Is a little more than 10% of my refund. Moral of the story if your place of work is accurate with their taxes you don’t need this. You’re better off not knowing because it just leaves a sour taste in your mouth knowing that they’ve taken your money to pay themselves. It will cost as much as my refund to get to the bank to deposit it so don’t waste your time.
