Every business has a duty to pay tax, whether that is Corporation Tax, VAT, PAYE, or personal tax liabilities for the owners. While these payments are predictable, many businesses still find themselves short of cash when the due dates arrive. One way to reduce this risk is to create a cash deposit reserve specifically set aside to cover past and current tax liabilities.

The idea is simple. Each time profits are made, or taxable income is earned, a proportion of cash is transferred into a separate bank account. This money is not touched for day-to-day trading but held back until HMRC requires payment. By treating tax as an ongoing expense rather than an occasional shock, businesses can avoid last-minute scrambles to find funds.

There are several benefits. First, a reserve provides peace of mind. Business owners know that when the tax bill lands, the money is ready and waiting. This reduces stress and allows management to focus on running and growing the business.

Second, a tax reserve supports cash flow planning. By separating tax money from working capital, it becomes clearer how much is genuinely available for wages, suppliers, or investment. Mixing tax liabilities with general funds often leads to overspending and unnecessary borrowing.

Third, building up a reserve shows financial discipline. It reassures banks, investors, and other stakeholders that the business takes its responsibilities seriously and manages risk sensibly.

Even small, regular transfers can make a big difference. By keeping tax reserves in a deposit account, businesses may also earn some interest before payments fall due.

In short, creating a tax reserve is a practical and prudent step. It reduces surprises, improves cash flow visibility and ensures that tax obligations are met without disrupting business operations.

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.

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.

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.

The Chancellor of the Exchequer, Rachel Reeves confirmed, in a video message, that the next UK Budget will take place on Wednesday, 26 November 2025.

Details of all the Budget announcements will be made on a special section of the GOV.UK website which will be updated following completion of the Chancellor’s speech in November.

HM Treasury is inviting written representations for the Autumn Budget 2025 from individuals, interested groups, MPs and organisations. Submissions should propose evidence-based policy ideas or comment on existing policies, with clear rationale, costs, benefits, and deliverability. The deadline for submissions is 23:59 on Wednesday, 15 October 2025.

The Budget will be published alongside the latest forecasts from the Office for Budget Responsibility (OBR). This forecast will be in addition to that published for the Spring Statement and fulfil the obligation for the OBR to produce at least two forecasts in a financial year, as is required by legislation.

The OBR has executive responsibility for producing the official UK economic and fiscal forecasts, evaluating the government’s performance against its fiscal targets, assessing the sustainability of and risks to the public finances and scrutinising government tax and welfare spending.
