The government tax calculator has me four hundred quid short every month. Another website called listentotaxman has me one hundred quid a month short.
Is there a service that can help explain this to me? All the tax advisors I've found online seem to be about tax returns for the self employed, or tax for companies/ employers.
HMRC themselves have huge backlogs and I don't know what their response time is like.
Any ideas please? I'm in Edinburgh, the land of solicitors and wealth managers.
