FAQ Section
Q: Do I need to register for VAT? A: Only if your taxable turnover exceeds £90,000 in a rolling 12-month period – though voluntary registration can make sense earlier depending on your customers and costs.
Q: What is Making Tax Digital and does it affect me? A: VAT returns must be filed through MTD-compatible software. We handle this as part of your bookkeeping, so you never have to think about it.
Q: Would the flat rate scheme suit my business? A: It depends on your costs and sector – for some service businesses it generates a genuine surplus, for others standard VAT accounting works out better. We’ll work out which suits you.
Q: What if I’ve registered late, or missed a return? A: Backdated VAT liability plus penalties can apply. The sooner we catch it, the smaller the bill – get in touch and we’ll sort it.
