The Difference Between Cash Basis and Traditional Accounting: Which Is Best for Your Business?

There are two ways to calculate profits for partnerships and sole traders namely being cash basis and traditional accounting. This blog will consider these two approaches in terms of which is useful for your business.

Finding the best accounting method for your business.

Cash Basis Accounting

Cash accounting is a simpler form in terms of calculating profit and loss by simply recording income and expenditure when they occur.

Example of Cash Basis Accounting

Imagine you run a small bakery. You bake cakes and sell them to customers.

  • On 10th January, a customer orders a birthday cake for £100 and agrees to pay later.
  • You deliver the cake on 12th January, but the customer pays you on 15th January.

In cash basis accounting, you only record the income on 15th January when you receive the payment, not when you made the sale.

Similarly, if you buy ingredients on 5th January for £30 but pay the supplier on 10th January, you only record the expense on 10th January when the money actually leaves your account.

 

Key takeaway: In cash basis accounting, income and expenses are recorded only when money is received or paid, making it easier for small businesses to track their actual cash flow.

What cannot be claimed as income or expenditure?

–  Expenditure on equipment, vans are recognised as allowable expenses

–  Losses from previous year cannot be offset by other income

–  The business will not be able to claim capital allowance except on cars

–  Interest based on cash borrowing will only be allowable up to £500

Cash basis accounting is useful as it enables your business to assess the actual amount of cash you have at any given time. If a business decides to use cash basis as their method of accounting, and they are eligible for it, then it’s important to tick the ‘cash basis’ box when preparing the self-assessment tax return.

 

Why Use Cash Basis Accounting?

Cash basis accounting is ideal for small businesses, sole traders, and partnerships with straightforward finances. Here’s why:

  • Simple to Use – You only record transactions when money enters or leaves your business, making bookkeeping easier.
  • Better Cash Flow Management – Since you only pay tax on money received, you won’t pay tax on unpaid invoices.
  • Fewer Adjustments – No need to track debtors, creditors, or unpaid invoices, reducing paperwork.
  • Easier Tax Calculations – You only declare income received in the tax year, simplifying Self-Assessment tax returns.
  • Lower Administrative Costs – Less complex accounting means you may not need an accountant, saving money.

However, cash basis accounting may not be suitable if your business has high stock levels or requires bank loans, as lenders prefer businesses with full financial records.

Recording income and expenditure as they occur for cash basis accounting.

Traditional Accounting

Traditional accounting is different than cash basis as it is based-on accrual, meaning that income and expenses are recorded as soon as you send invoices to customers or receive a bill.

Once a business earns above the threshold of £300,000, they will have to start using the traditional accounting method.

Example of Traditional Accounting (Accrual Accounting)

Let’s say you run a small web design business.

  • On 1st March, you complete a website project for a client and send them an invoice for £2,000, but they will pay you later.
  • The client pays you on 15th April.

In traditional accounting, you record the income on 1st March, the date you issued the invoice, even though you haven’t received the payment yet.

Similarly, if you purchase a new laptop for £800 on 10th March using a credit card but plan to pay the bill in April, you still record the expense on 10th March, the date of purchase.

 

Key takeaway: Traditional accounting records income and expenses when they are earned or incurred, not when money is actually received or paid. This gives a clearer long-term view of a business’s financial health.

What information is required to record income and expenditure?

– Value of stock at the end of accounting period

– Purchase receipts of business assets

– Employee related payments

– Bank interest

– Any other income

– Year end balances

– Drawings

The reason traditional accounting can be more useful is that it provides a realistic and long-term view of the transactions of the business which the cash basis fails to show. However, the accrual basis requires constant monitoring as a business may be profitable under the traditional accounting method but may not have any actual cash.

If a business has an expense which continues after the financial year end, then it’s important for the business to use a proportionate basis in order to spread the cost in the period which it belongs to.

 

Why Use Traditional Accounting?

Traditional accounting is more detailed and provides a full financial picture of your business. Here’s why it’s beneficial:

  • Required for Larger Businesses – If your turnover exceeds £300,000, you must use traditional accounting.
  • Better Business Planning – It helps track money owed to and from the business, giving a clearer financial position.
  • Loss Relief – You can offset losses against other income to reduce tax liability.
  • Improves Business Credibility – Banks and investors require detailed financial statements when granting loans or funding.
  • Tracks Profitability Accurately – Since income and expenses are recorded as they occur, you get a true picture of business performance.

However, traditional accounting requires more record-keeping and may result in tax being due before cash is received, making cash flow management essential.

HMRC Requirement of Financial Rrecords

If you are a self-employed individual, its required for your business to retain records for at least five years after the January 31 deadline, whether you are using cash basis or traditional accounting, in case HMRC require any information about how your business has calculated the tax liability.

Keeping financial records for HMRC.

The difference between cash basis and traditional accounting

The major difference between the two methods is timing.

If the traditional accounting method is employed then your business may end up reporting income before you have received any cash payment, hence why this is the reason why some sole traders prefer cash basis. Traditional accounting can lead to your business paying tax on income, however if cash basis been used then tax have been charged the following year.

Which Scheme is Better for Your Business?

Cash Basis:

There are certain rules to be eligible to use the cash scheme, for example:

 

– It can only be used by small businesses such as a sole trader or partnership.

– The turnover must be less that £150,000.

 

As a result, cash basis accounting cannot be used by limited companies and limited liability partnerships, such as bank underwriters or businesses selling securities, therefore they have to use traditional accounting to calculate their taxable profits.

Traditional Accounting

Traditional Accounting is used by larger businesses and is often used in situations where cash basis accounting has limitations, for example:

 

  • Cash basis does not suit businesses with high level of stocks.
  • Loss relief can be used through traditional accounting.

 

Businesses requiring finance from the bank are often questioned to show accounts showing income and expenditure which requires traditional accounting.

 

Overall, the question as to whether your business should use cash basis or traditional accounting depends on the size of your business, the turnover and whether the business has a limited or unlimited liability. It is common that cash basis accounting is used by small businesses whereas traditional accounting is used by larger businesses.
