Understand your VAT position in seconds
VAT is charged at a standard rate of 20% on most goods and services, with reduced (5%) and zero rates on specific categories. Businesses must register once taxable turnover passes £90,000 in any rolling 12-month period. VATwise helps you check figures, dates and numbers quickly — then confirm anything material with a qualified accountant.
