Every business needs a cash reserve: wages, VAT and corporation tax, suppliers, a slow quarter and any investment it has planned. The right figure comes from the company's own numbers, not a rule of thumb. We build it from your monthly costs, tax dates and plans, and agree it with you and your accountant.
Cash above the reserve is a decision, not a default. Left on deposit, it is taxed every year and loses ground to inflation. Moved with a plan, it can fund your pension or be invested in the company's name.
