View your calculation is the amount you pay. That's the HMRC tax calculation on the figures you've put in.
I got a fine from HMRC. For not sending in my 20/21 accounts. I wrote to them in 2018 to say I'm no longer Self Employed and gave them my finishing accounts. Heard nothing, then all of a sudden this year got sent a £1300 fine. They've not responded to my letters and impossible to get through online or by phone. Any help please?
