Understanding working capital and why it matters

Working capital is a simple but powerful measure of a business’s financial health. It is the difference between current assets and current liabilities. In other words, it shows what is left when a business’s short-term debts are taken away from its short-term resources such as cash, stock and money owed by customers.

If the result is positive, the business has money available to cover day-to-day operations. If it is negative, the business may struggle to meet upcoming bills or need to rely on borrowing.

Why is working capital so important? First, it gives a clear picture of liquidity. A profitable business can still fail if it runs out of cash to pay suppliers, wages, or rent. By keeping a close eye on working capital, owners can see whether they have enough resources to keep the business running smoothly.

Second, working capital affects flexibility. A business with strong working capital can take opportunities such as bulk-buying stock at a discount or investing in new projects. A business with weak working capital may be forced to delay decisions or turn down growth opportunities because it cannot afford the risk.

Third, lenders and investors often look at working capital when deciding whether to support a business. A healthy balance suggests stability and good management, while a weak position may raise concerns.

Improving working capital does not always mean cutting costs. It can involve speeding up customer payments, negotiating longer terms with suppliers, or keeping a closer watch on stock levels. Even small changes can make a big difference to cash flow.

In short, working capital is about making sure a business can meet today’s needs while staying ready for tomorrow’s opportunities.

How do HMRC define “wholly and exclusively” for tax purposes

Not sure if a business cost is deductible? HMRC’s ‘wholly and exclusively’ rule is the key test.

When deciding whether an expense is deductible or not it is important to bear in mind that the expenditure must be incurred wholly and exclusively for the purposes of your trade or employment. This is a difficult starting point as there is often a fine line to thread between deciding whether an expense meets this ‘wholly and exclusively’ rule.

In general, HMRC takes a slightly more relaxed view that a strict reading of the legislation would suggest. HMRC’s own internal manuals offers advice to HMRC inspectors to exercise care when applying the ‘wholly and exclusively’ test. The advice states that where there is an incidental benefit that does not, of itself, mean that the expenditure is disallowed.

The following example helps clarify this point. A self-employed consulting engineer may travel to exotic locations to advise on projects. The travel and the exotic locations may be benefits but where there was no private purpose they are incidental to the carrying on of the profession and the cost is allowable.

It is also possible to apportion part of an expense where necessary. For example, when considering the running costs of a car used partly for the purposes of the trade and partly for other purposes. HMRC’s position is that the costs associated with the business use of the car would be deductible.

When you cannot charge VAT

Not all goods and services carry a 20% VAT, knowing the right rate can save costly mistakes.

When a VAT-registered business issues an invoice to their customer, they must ensure that they charge the correct rate of VAT. Whilst most businesses in the UK charge VAT at the standard rate of 20% there are a number of different VAT rates and exemptions to be aware of. This includes the reduced VAT rate of 5% and the zero rate (0%).

There are two other categories that the supplies of goods and services can fall under:

  • Exempt – where no VAT is charged on the supply. Examples of exempt items include the provision of insurance, postage stamps and health services provided by doctors. If a business only sells VAT-exempt goods and services, they cannot register for VAT.
  • Supplies that are 'outside the scope' of the UK VAT system altogether. These supplies are beyond the realm of the UK VAT system, and you cannot charge or reclaim VAT on these supplies. Examples include goods or services you buy and use outside of the UK, statutory fees (such as the London Congestion Charge) and goods you sell as part of a hobby.

If a business has made an error in charging VAT, then this needs to be corrected. The timing and amount of an error can impact on how the issue is resolved.

There are also penalties if you charge VAT to your customers before you are officially VAT registered. VAT registration is only required for eligible businesses earning more than £90,000 per year although businesses under the threshold can voluntarily apply for a VAT registration.

Using your own car for work purposes

Using your own car or bike for work travel? You may be able to claim tax relief for business mileage.

If you are employed and spend your own money on items needed for your job, you may be eligible to claim tax relief on those expenses. However, you can usually only claim tax relief on items that are exclusively used for work purposes.

For example, you might be able to claim tax relief when using your own vehicle, whether it is a car, van, motorcycle or bicycle, for work-related travel. Generally, travel between home and your regular place of work does not qualify. However, if you travel to a temporary workplace or incur business mileage, tax relief is typically allowed.

Employers often reimburse mileage using a set rate per mile depending on the type of vehicle. HMRC publishes approved mileage rates that apply when employees use their own vehicles for business journeys. If your employer uses these rates, the reimbursement is not treated as a taxable benefit.

If you are reimbursed at a rate below the HMRC approved amount, you can claim tax relief on the difference through Mileage Allowance Relief. For cars, the rate is 45p per mile for the first 10,000 miles and 25p per mile thereafter. The rate is 20p per mile for bicycles and 24p per mile for motorcycles.

Additionally, there is a passenger payment of 5p per mile per colleague if you transport other employees during business journeys in a car or van.

How to pay corporation tax online

Paying Corporation Tax? Always use the correct reference or risk delays and penalties.

To pay Corporation Tax via online or telephone bank transfer, you can use either a UK or overseas bank account.

UK Bank Accounts

You can transfer funds using Faster Payments, CHAPS, or Bacs, either online or by calling your bank. Faster Payments usually reach HMRC on the same or next day (including weekends), CHAPS payments arrive the same working day if made within your bank’s cut-off time, and Bacs payments typically take up to 3 working days.

Use the account details provided in your HMRC ‘notice to deliver your tax return’ or reminder. If unsure, use one of the following:

  • HMRC Cumbernauld
    • Sort code: 08 32 10
    • Account number: 12001039
  • HMRC Shipley
    • Sort code: 08 32 10
    • Account number: 12001020

Overseas Bank Accounts

You can also pay from an overseas account using:

  • HMRC Cumbernauld
    • IBAN: GB62 BARC 2011 4770 2976 90
    • BIC: BARCGB22
  • HMRC Shipley
    • IBAN: GB03 BARC 2011 4783 9776 92
    • BIC: BARCGB22

You must ensure to include your 17-character Corporation Tax payment reference number for the correct accounting period. This reference changes each year so it is important to use the up-to-date reference number. Using the wrong one can delay your payment. You can find it in your company’s HMRC online account or on your ‘notice to deliver your tax return’ or on any reminders from HMRC.
