Cash Basis vs Accrual Accounting: Which Should Your Small Business Use?

Cash basis vs accrual accounting comes down to timing. Cash basis records income when the money is received and expenses when they are paid. Accrual accounting records them when the invoice is raised or the bill is incurred. Limited companies must use accrual accounting.

One of the earliest decisions a small business owner has to make is how to record income and expenses. Do you count money when it actually lands in your bank account, or when the invoice is raised?

This choice, between cash basis and accrual accounting, affects how your profit is calculated, how your tax bill is worked out, and how clearly you can see the true financial health of your business.

At R&R Chartered Certified Accountants, we help small business owners across Blackburn and the Northwest choose the right accounting method and set it up correctly from the start.

Here is what you need to know about cash basis and accrual accounting, and how to decide which suits your business.

What Is Cash Basis Accounting?

Cash basis accounting is the simpler of the two methods. Under this approach, you record income when you actually receive payment and expenses when you actually pay them, rather than when the invoice was issued or received.

This method is popular with sole traders and smaller businesses because it closely mirrors what is actually happening in your bank account, which makes it easier to understand without an accounting background.

It is also generally simpler for tax purposes, since you are only taxed on money you have genuinely received rather than income you are still waiting on.

The downside is that cash basis accounting can give a distorted short term picture.

If you invoice a large job in March but do not get paid until May, that income simply will not appear in your March figures at all, even though the work is done and the invoice is out.

This can make it harder to judge how your business is really performing at any given point.

Recommended action: Since the 2024/25 tax year, cash basis has been the default method for sole traders and most partnerships, and there is no longer a turnover limit.

Check that it still suits your business before you file your self assessment tax return. You can opt out and use accrual accounting instead, which often suits businesses that hold stock or offer credit terms.

What Is Accrual Accounting?

Accrual accounting works differently. Under this method, you record income when it is earned, meaning when the invoice is raised, and expenses when they are incurred, meaning when the bill is received, regardless of when the money actually changes hands.

This gives a more accurate and complete picture of your business’s financial position at any point in time, since it reflects work done and costs committed to, not just cash that has physically moved.

It is particularly useful if your business holds stock, offers credit terms to customers, or has significant amounts owed to or by the business at any given time.

The trade off is complexity. Accrual accounting requires tracking debtors, creditors and stock more carefully, and it is the required method for limited companies preparing statutory accounts, which adds a layer of administrative work that cash basis does not require.

Recommended action: If your business holds stock, extends credit to customers, or is a limited company, plan for accrual accounting from the outset and make sure your bookkeeping software is set up to track debtors and creditors properly, rather than trying to retrofit this later.

Which Method Is Right for Your Business?

The right choice largely comes down to the structure and complexity of your business, and there is no single correct answer for everyone.

If you are a sole trader or a very small business with simple, mostly cash based transactions and no significant stock or credit arrangements, cash basis accounting is often the more practical and lower admin option.

HMRC’s simplified rules are designed with exactly this kind of business in mind.

If you run a limited company, hold stock, or regularly invoice customers on credit terms, accrual accounting is likely to give you a far more accurate view of your actual financial position.

For a limited company it is a legal requirement rather than a choice.

It is also worth remembering that your accounting method does not have to stay fixed forever. As your business grows and its transactions become more complex, moving from cash basis to accrual accounting is a natural step many businesses take.

Recommended action: Speak to your accountant before choosing or switching methods, since getting this decision right from the start avoids the cost and disruption of restating figures or amending tax returns further down the line.

Frequently Asked Questions

Is cash basis or accrual accounting better for a small business?

It depends on how you trade. Cash basis suits sole traders and small businesses with simple transactions, no stock and no credit terms. Accrual accounting suits businesses holding stock, invoicing on credit, or trading as a limited company, because it shows a fuller picture of profit and position.

What is the difference between cash basis and accrual accounting?

Cash basis records income when the money is received and expenses when they are paid. Accrual accounting records income when the invoice is raised and expenses when the bill is incurred, regardless of when cash moves.

Can a limited company use cash basis accounting?

No. Limited companies must prepare statutory accounts on the accrual basis. Cash basis is for sole traders and most partnerships reporting through self assessment, and since the 2024/25 tax year it has been their default method unless they opt out.

Does cash basis accounting affect how much tax I pay?

It affects the timing rather than the total over the life of the business. Under cash basis you are taxed on money actually received in the year, so income invoiced but unpaid at the year end falls into the following tax year.

Can I switch from cash basis to accrual accounting?

Yes. Many businesses move to accrual accounting as they grow, take on stock or start offering credit terms. Switching involves adjustments so that income and expenses are not counted twice, so speak to your accountant before you change method.

The Bottom Line

Cash basis and accrual accounting each have their place, and the right choice depends on how your business operates rather than personal preference alone.

Simple businesses with straightforward cash transactions often do well with cash basis accounting, while businesses holding stock, offering credit, or trading as a limited company usually need the fuller picture that accrual accounting provides.
