Too much cash in the company? | Severn Accounting

Although many companies are facing difficult times, some have managed to accumulate a sizeable amount of cash in their business’s current account. Leaving this cash where it is brings with it the impact of inflation eroding its real value, whilst also raising questions from HMRC about whether the funds are being deployed efficiently. If you’re in this position, it’s worth considering your options carefully—both from a tax perspective and a commercial one.

The Inflation Problem

In recent years, inflation has significantly impacted business finances. Cash sitting idle in a current account earning minimal interest loses purchasing power month on month. With inflation hovering around 4% (as of 2024/25), money in a low-interest account is effectively shrinking in real terms. This is particularly relevant if you’re planning future capital purchases or wage increases; the longer you wait, the more expensive those expenditures become.

Beyond the erosion issue, having surplus cash can signal to stakeholders—including lenders, investors, and sometimes HMRC—that capital isn’t being managed strategically. From a business perspective, it raises questions about growth plans, dividend policy, and why profits aren’t being reinvested in the company’s development.

Corporation Tax and Retention

One important consideration is corporation tax. If your company is profitable and retaining earnings, you’ll have already paid corporation tax at 19% (or 25% if your profits exceed £250,000 in the current tax year). Leaving that after-tax cash in the bank is a legitimate business decision, but it’s worth being intentional about it.

If you’re considering extracting cash as dividends, remember that dividends are paid from post-tax profits. Shareholders then face dividend tax—currently 0% on the first £500 of dividend income (the dividend allowance), then 8.75% for basic-rate taxpayers and 39.35% for higher-rate taxpayers. This layering of tax means extracting everything as dividends isn’t always the most efficient route.

Alternatively, if the cash will genuinely be needed for business purposes within the next 12 months, retention is perfectly sensible. HMRC won’t challenge reasonable commercial decisions about retained earnings.

Investment and Growth Options

Many businesses find that reinvesting surplus cash creates genuine value. This might mean:

Capital expenditure: Plant, machinery, or property. You may benefit from capital allowances, which can reduce taxable profits.
R&D investment: If eligible, R&D tax relief can yield significant credits—up to 33.35% of qualifying costs for loss-making companies.
Staff development: Training, recruitment, and wage increases can strengthen your team and support growth.
Working capital: Building reserves for seasonal fluctuations or unexpected challenges.

These aren’t just tax-efficient strategies; they’re often commercially sensible too.

Higher Interest Accounts and Treasury

If you need to keep cash accessible but want better returns, consider:

Business savings accounts: Some banks now offer competitive rates for business deposits, though still modest by historical standards.
Money market funds and notice accounts: These can offer slightly better returns than standard current accounts, though with reduced liquidity.
Premium bonds or gilts: Lower-risk options, though returns remain modest.

The key is ensuring any investment aligns with your business’s liquidity needs. You don’t want to lock cash away if you need it for operational flexibility.

Getting HMRC’s Attention

Interestingly, HMRC becomes concerned not when you retain profits, but when your company accumulates cash without clear commercial purpose. They may scrutinise whether retained profits are genuinely for business use or whether they’re being sheltered for personal advantage. Having a documented strategy—whether that’s capital investment plans, working capital reserves, or planned distributions—demonstrates commercial rationale.

If you’re a close company (broadly, a company controlled by five or fewer shareholders), there are additional considerations around loan relationships and distributions that you should discuss with your accountant.

The Bottom Line

Surplus cash presents an opportunity, not a problem. Whether you retain it, invest it, or distribute it depends on your business’s needs and your personal circumstances. The important thing is to make an active decision rather than letting it accumulate by default.

Tax efficiency, cash flow management, and commercial strategy should all inform your approach. What makes sense for one business won’t necessarily work for another, which is why professional advice is invaluable.
