Cash reserves
Business savings accounts: balance interest, access and protection
Cash set aside for tax, quiet periods or investment can earn interest. The challenge is choosing an account that keeps that money available when you actually need it.
Quick answer
A business savings account holds reserves rather than running everyday payments. Decide when each part of the balance may be needed, then compare access restrictions, the interest calculation, eligibility and protection. A higher rate is not helpful if it forces expensive borrowing to meet a bill.
Key points
- Keep enough accessible cash for known bills and plausible trading shocks before locking money away.
- Easy-access, notice and fixed-term accounts solve different timing needs.
- AER helps compare annualised interest, but withdrawal rules, variable rates and bonus periods still matter.
- Eligible deposits generally share a £120,000 FSCS limit per depositor, per authorised firm—not per account.
What is a business savings account for?
A business savings account is normally used for money not needed in the day-to-day current account. Examples include a tax reserve, an emergency buffer, seasonal cash or money earmarked for equipment. Interest is a potential return for holding the balance under the account’s conditions, not a reason to ignore operational needs.
Savings accounts often lack debit cards, Direct Debits and the payment facilities of a current account. Withdrawals may have to go through a nominated account in the business’s name. Check the route from savings back to payroll or supplier payments before moving essential cash. A deposit account is also different from an investment fund, where capital can rise or fall and protection rules differ.
Separate operating cash, reserves and genuinely spare funds
Start with a cash-flow forecast and a calendar of commitments. Identify wages, rent, supplier payments and tax dates, then consider uncertainty such as delayed customer payments or seasonal sales. Do not label the whole current-account balance as spare simply because it has not been spent yet.
It can help to think in separate pots: money needed soon, a buffer for unexpected demands, and funds with a genuinely longer horizon. The size of each depends on your business rather than a universal rule about how many months to hold. Review the plan when costs, trading conditions or tax estimates change. An accountant can help reconcile reserves with liabilities.
- Map known payment dates before choosing an account term.
- Allow for weekends, bank holidays, transfer limits and processing times.
- Keep contingency money accessible rather than assuming credit will be available.
- Check who can authorise withdrawals if a director is unavailable.
Easy access, notice or fixed term: which fits the timing?
An easy-access account generally offers more flexible withdrawals, but the name does not guarantee instant transfers or unlimited access. A notice account normally requires advance notice before withdrawal. A fixed-term account usually locks money away until an agreed maturity date, often with no early withdrawal option.
Read the actual conditions. There may be withdrawal limits, nominated-account requirements, minimum balances or a different rate after a withdrawal. A fixed rate describes the interest terms; it does not automatically mean the money can be accessed for a penalty. Confirm the exit rules before treating an account as an emergency reserve.
| Account type | Potential use | Main restriction to check |
|---|---|---|
| Easy access | Bills and reserves that may be needed soon | Transfer times, withdrawal limits and variable rates |
| Notice account | Money with a reasonably predictable future use | Required notice and whether early access is possible |
| Fixed term | Funds not expected to be needed before maturity | Lock-in period, maturity instructions and early-access rules |
Compare the interest basis, not just the headline number
AER, or annual equivalent rate, expresses interest on an annualised basis with compounding reflected where applicable. A gross rate is quoted before tax. Check whether interest is paid monthly, annually or at maturity, whether it stays in the savings account and whether the advertised rate assumes that it does.
Look for introductory bonuses, balance tiers and conditions that change the return. A variable rate can move after opening; a fixed rate usually applies for the specified period under the account terms. Use a common balance and time period when comparing accounts. A high headline rate applying only to a small slice of your money is not the same as that rate on the whole balance.
What could the interest difference mean in pounds?
For illustration only, £20,000 held for a full year at 3% would produce £600 before tax if there are no balance changes and those are the effective annual terms. At 3.5%, it would produce £700 under the same assumptions. The additional return is £100. These are invented rates, not market offers, and actual calculations depend on the provider’s terms.
Put that difference beside the cost of losing access. If withdrawing early is prohibited, or a cash shortfall forces borrowing costing more than the extra interest, choosing the higher rate may be a poor operational trade-off. Do not compare a full-year illustration with money you expect to withdraw in a few weeks.
| Balance | Assumed annual rate | Illustrative interest |
|---|---|---|
| £20,000 | 3% | £600 |
| £20,000 | 3.5% | £700 |
| Same assumptions | 0.5 percentage-point difference | £100 extra |
How does FSCS protection apply to business savings?
The standard FSCS deposit limit increased to £120,000 on 1 December 2025. It applies per eligible depositor, per UK-authorised bank, building society or credit union. Current accounts and savings under the same banking licence are normally added together. Opening another account at the same firm does not create a new limit.
An eligible limited company or LLP is normally treated separately from its owner’s personal deposits. For a sole trader, personal and business balances at the same authorised firm are combined. Check the actual authorised bank, not just the brand on the app. Some businesses, including many regulated financial services firms, may not qualify; ask the provider about your position rather than assuming every company is covered.

Check who actually holds the deposit
If you use a savings platform, intermediary or branded app, identify the underlying bank and which of your other accounts share its licence. Read the terms for money moving through a holding or transit account, as its treatment may differ from the final deposit. Keep a record of balances across providers, including interest.
A non-bank payment account is not equivalent to an FSCS-protected deposit simply because its provider is regulated. The FCA explains the safeguarding rules for payment and e-money firms and the potential delays and deductions if a firm fails. Likewise, a product described as a cash investment or money market fund should not be assumed to have bank-deposit protection.

Keep interest and tax records in the correct name
A company’s interest receipts need to be recorded in its accounts and considered under the relevant tax rules. GOV.UK explains that Corporation Tax can apply to investment profits as well as trading profits. Do not apply an individual’s Personal Savings Allowance to a limited company’s money or assume that interest received without a deduction is tax-free.
Sole traders and partnerships can have different reporting and ownership considerations. Ask an accountant how interest on your particular account should be treated; the account’s label alone is not a complete tax analysis. Retain statements showing interest earned, payment dates and the legal account holder. Tax treatment depends on circumstances and can change.

Before moving reserves or renewing a fixed term
Check eligibility for your legal structure, minimum deposits, maximum balances, transfer limits, fees and the withdrawal route. Record the interest basis and whether it is fixed, variable or includes a temporary bonus. Ask what happens if the balance falls below a threshold and what instructions are needed at maturity.
Set a reminder before a fixed term or bonus ends. Review cash needs and protection again rather than allowing an automatic rollover into an unsuitable term. If the business also has borrowing, compare the after-tax return and liquidity value with the cost and conditions of repayment, including any settlement charge. That is a business-specific decision, not a rule that savings always beat debt repayment or vice versa.

Common questions
- Can my business have savings with a different bank?
- Often yes, subject to the provider accepting your business type and meeting its opening requirements. Check whether it requires an existing current account and how a nominated account must be verified.
- Is an easy-access business savings account instant?
- Not necessarily. Withdrawal windows, payment limits, processing times and nominated-account rules vary. Test the transfer route before relying on it for a time-critical bill.
- Does my company get a separate £120,000 limit for every savings account?
- No. Eligible deposits at the same authorised firm normally share a single depositor limit. Current and savings accounts, and brands sharing a licence, must be considered together.
- Should I put tax money in a fixed-term account?
- Only consider a term if the money is definitely accessible before the liability must be paid and you have allowed for timing uncertainty. The account paying the most interest is not necessarily suitable for money needed on a specific tax date.
