Guides
Plain-English explanations of the UK tax rules our tools are built around: Making Tax Digital, Self Assessment expense categories and VAT. Each guide is checked against GOV.UK guidance and dated, so you can see when it was last reviewed.
Making Tax Digital
Making Tax Digital for Income Tax: who, when and how
The full picture: thresholds and start dates, what qualifying income means, digital record rules, quarterly updates, penalties and how to prepare.
Deadlines
MTD quarterly deadlines and update periods
The four update periods and their deadlines, the calendar-quarter election, cumulative updates and what happens if you miss one.
Self Assessment
SA103 expense categories explained
Box-by-box walkthrough of the self-employment expense headings, allowable and disallowable examples, and simplified expenses rates.
VAT
UK VAT rates explained
Standard, reduced and zero rates with real examples, the zero-rated versus exempt distinction, and current registration thresholds.
The tools these guides support
Each guide pairs with a free tool: the bank statement analyzer for extracting and categorising transactions, the receipt scanner for expense records, the VAT calculator for estimating VAT return figures, and the quarterly reporter for grouping a year of statements into MTD quarters.
Our guides are general information, not tax advice. Rules change and individual circumstances differ; always check current GOV.UK guidance or ask a qualified adviser.
