UK Tax, Accounts & SME Advisory
UK tax, accounts and SME advisory
Mercy Oyelowo works in UK tax, accounts preparation and small-business advisory — the day-to-day end of the profession, where the same handful of questions come up again and again from people running something small.
At TaxFly she reviews the self-employment and small-business guides: registering with HMRC, the trading allowance, record-keeping, Making Tax Digital for Income Tax and the first self assessment. Her benchmark is whether someone with no accountant could follow the guide and file correctly.
