What we do with this

We prepare the personal return, not the company’s

If you draw a salary and a dividend, run a business alongside employment, or hold equity in a company you part-own, all of that lands in your personal return — and that return is ours to prepare. The company’s own filings, its VAT, and its payroll are not.

Work involving business income is quoted per case, after we have seen the books, because the effort genuinely varies. The three fixed-price packages on the pricing page cover employment income, equity, foreign assets and property.
