Limited company banking: keep company money separate and controlled

A limited company is legally separate from its owners. Its banking should reflect that separation, with company income and expenses kept away from personal money and with clear authority over who can move funds.

Keep company banking clearly separate from personal banking

GOV.UK states that there must be a clear division between the company's finances and those of owners and directors because the company is a separate legal entity. It explicitly says company banking must be separate from personal banking and identifies opening a business bank account as the simplest way to achieve that.

That means customer receipts, supplier payments, payroll and company expenses should move through company-controlled accounts. Directors should not treat the company bank balance as personal money. Salary, expense reimbursement, dividends and director loans each have their own accounting and tax treatment, so transfers to directors should be recorded correctly rather than made as unexplained withdrawals.

Define who can view, create, approve and administer payments

At formation, one director may control everything. As the company grows, split access by responsibility. A bookkeeper may need view and export rights, a finance manager may create payments, and a director may approve larger transfers. Named credentials are better than a shared login because they create a clearer audit trail.

Set approval thresholds based on business impact. A £200 office purchase does not need the same process as a £100,000 supplier payment. Beneficiary changes and first payments can deserve a second check even at lower values. Also keep a secure backup approver so payroll and tax do not depend on one person's phone being available.

Use the banking setup to support the company's accounting-record duties

GOV.UK requires limited companies to keep accounting records including money received and spent, assets owned, debts owed and other information needed to prepare company accounts and Corporation Tax returns. Bank statements form part of the supporting evidence, but they should connect cleanly to invoices, payroll, receipts and accounting entries.

Use bank feeds or structured exports where practical and reconcile every active account. Transfers between company accounts should be recorded as transfers, not income or expense. Keep evidence for director expenses and company-card spending. A finance team should be able to trace a material payment from bank transaction to approval, invoice and ledger entry without reconstructing the story from email months later.

Separate VAT, Corporation Tax and payroll cash from the operating balance

A company's bank balance can overstate free cash because some money is already committed to HMRC, payroll or pensions. Maintain a tax calendar and use separate savings pots or accounts where that improves discipline. Corporation Tax is usually due nine months and one day after the accounting period ends for companies outside the instalment-payment rules, while VAT and payroll have different deadlines.

For example, a company may show £250,000 across its accounts but already expect £60,000 of VAT, £45,000 of Corporation Tax and £70,000 of payroll and supplier commitments in the next month. Management should make investment or dividend decisions from the forecast free-cash position rather than the headline balance.

Manage reserve cash by purpose, access and protection

Separate operating cash from money not needed immediately. Short-term reserves may belong in easy-access savings, while genuine surplus can potentially tolerate notice or fixed terms. Match maturity to the cash-flow forecast rather than choosing purely on interest rate.

For eligible company deposits, FSCS protection can apply subject to the rules and the authorised firm holding the money. Check shared banking licences if large balances are spread across different brands. If the company uses a non-bank payment or e-money provider, understand the safeguarding model instead of assuming the balance has the same protection as a bank deposit.

Prepare for more users, borrowing and additional entities before the account becomes a bottleneck

Review the banking setup before hiring finance staff, taking substantial borrowing, opening another company or expanding internationally. The account that worked for one director may lack dual approval, user roles, higher payment limits or accounting connectivity required by a larger operation.

If the group adds another legal entity, do not casually combine cash flows. Each company should have records that reflect its own transactions, intercompany transfers and liabilities. As complexity grows, the objective is not to collect more bank accounts. It is to make authority and cash ownership clearer, not harder to understand.

Growth also changes the service expectations around the account. A company that starts paying hundreds of suppliers, using several cards or sending large international transfers should confirm online limits, bulk-payment tools, support routes and fraud controls before the existing setup becomes a bottleneck. Review banking as part of each major operating change rather than waiting for a failed payment or access problem to expose the weakness.
