Every business incurs costs before it pays them. Electricity used in December but billed in January. Staff who earn wages on the last day of the month but are paid days later. Professional fees invoiced after the work is done. These are not unusual situations, they are everyday realities of how business operates. Accrual accounting exists to capture these costs accurately, and accrued expenses are the mechanism that makes it work. This guide explains both concepts clearly, with practical examples and journal entries throughout.
What Are Accrued Expenses?
An accrued expense is a cost that a business has incurred during an accounting period but has not yet paid or received an invoice for by the time the period ends. Despite the absence of a payment or bill, the expense is real, the obligation exists, and must be recognised in the financial statements for the period in which it was incurred.
Accrued expenses are also referred to as accrued liabilities. They represent a debt the business owes, even if that debt has not yet been formally invoiced.
In simple terms: An accrued expense is money you owe but have not yet paid, and have not yet been billed for.
Everyday Examples of Accrued Expenses
| Scenario | Accrued Expense |
| Staff work the last week of March but are paid in April | Accrued wages/salaries |
| Electricity consumed in Q4 but bill arrives in January | Accrued utility expense |
| Solicitor completes work in November, invoices in December | Accrued professional fees |
| Interest accumulates on a loan throughout the month | Accrued interest expense |
| Employees earn holiday entitlement not yet taken | Accrued annual leave liability |
| Business rates cover a period straddling two financial years | Accrued rates expense |
The critical distinction is timing. An accrued expense does not wait for a bill or a bank transfer, it is recorded when the obligation is created, not when cash changes hands.
What Is Accrual Accounting And How Does It Work?
Accrual accounting is the method of recording financial transactions when they are earned or incurred, regardless of when cash is received or paid. It is the foundation of modern financial reporting and the basis on which almost all formal business accounts are prepared.
The underlying principle is known as the matching principle: revenues and the expenses incurred to generate those revenues should be recognised in the same accounting period. This gives a far more accurate picture of financial performance than simply tracking cash movements.
A Simple Illustration
Imagine a business completes a project in March and sends an invoice for £10,000. The client pays in April.
- Under accrual accounting, the £10,000 revenue is recorded in March, the period the work was done and the income was earned.
- Under cash accounting, the £10,000 would only be recorded in April, when the cash arrives.
The accrual approach reflects economic reality. The work happened in March, the obligation was created in March, and the financial statements for March should reflect that.
The Two Sides of Accrual Accounting
Accrual accounting applies to both income and expenditure:
| Concept | What It Means |
| Accrued income (revenue) | Income earned but not yet received or invoiced |
| Accrued expense (cost) | Cost incurred but not yet paid or invoiced |
| Prepaid income | Cash received before the work is done |
| Prepaid expense | Cost paid in advance for a future period |
Accrued expenses are the cost-side application of the accrual principle, ensuring expenditure is matched to the period it relates to, not the period it is paid.
Accrued Expenses vs Accounts Payable | What’s the Difference?
This is one of the most common sources of confusion in accounting. Both accrued expenses and accounts payable are current liabilities, but they are not the same thing.
| Feature | Accrued Expenses | Accounts Payable |
| Invoice received? | No, expense incurred but not yet billed | Yes, invoice has been received |
| Amount known precisely? | Often estimated | Usually exact, stated on invoice |
| Created by | Time passing or work being done | Receipt of a supplier invoice |
| Examples | Accrued wages, accrued interest, accrued utilities | Supplier invoices, purchase orders |
| Balance sheet | Current liabilities, accruals | Current liabilities, trade payables |
| Certainty | May require judgment to estimate | Confirmed by a third-party document |
Both represent money the business owes. The difference lies in whether a formal invoice has been received and whether the amount is confirmed or estimated.
Common Types of Accrued Expenses in Business
Accrued expenses appear across virtually every area of business operations. Here are the most frequently encountered categories:
- Accrued Wages and Salaries: The most common accrued expense in most businesses. When a payroll period straddles a month-end or year-end, the portion of wages earned but not yet paid must be accrued. This includes basic pay, bonuses earned but not yet paid, and employer National Insurance contributions.
- Accrued Interest: Interest on loans, overdrafts, or other borrowings accumulates daily. Where interest is charged quarterly or annually, the portion accruing within each accounting period must be recognised as a liability, even if the cash payment falls in the next period.
- Accrued Utilities: Gas, electricity, and water bills often cover periods that do not align neatly with accounting month-ends. The cost attributable to the current period is accrued based on estimated consumption.
- Accrued Rent and Rates: Where lease agreements or business rates cover periods spanning two financial reporting periods, the relevant portion is accrued in the period it relates to.
- Accrued Professional Fees: Legal, audit, consultancy, and advisory services are often completed before the professional issues their invoice. The cost is accrued in the period the service was received.
- Accrued Tax Liabilities: Corporation Tax, VAT, and PAYE obligations accruing within a period are recognised as liabilities before the formal payment deadline arrives.
- Accrued Annual Leave: Under UK employment law and accounting standards, businesses must recognise the liability for untaken holiday entitlement as an accrued expense, calculated at the employee’s daily rate.
- Accrued Warranty Costs: Businesses that offer warranties on products must estimate and accrue the expected cost of future warranty claims arising from sales made in the current period.
Identifying which of these apply to your business is the first step toward building a complete and accurate period-end close process.
Why Businesses Use Both Concepts
Accrual accounting and accrued expenses are not separate tools, they are inseparable. Understanding why businesses rely on both helps clarify why these concepts exist in the first place.
Compliance with Accounting Standards
In the UK, businesses preparing accounts under UK GAAP (FRS 102) or IFRS are required to use accrual accounting. This is not optional for most businesses, it is the standard against which financial statements are judged by HMRC, Companies House, lenders, and investors.
Accurate Profit Measurement
Without accruals, reported profit could be significantly distorted. A business that incurs £50,000 of expenses in December but pays them all in January would show an artificially high profit in December and an artificially low one in January under cash accounting. Accruals smooth this out and present a true picture.
Informed Decision-Making
Management accounts built on accrual principles give business owners and directors a reliable view of performance. If your December management accounts show all December costs, including those not yet invoiced, you can make informed decisions about pricing, hiring, investment, and cash management.
Creditworthiness and External Reporting
Banks, investors, and trade creditors assess a business’s financial health using its accounts. Accrual-based financial statements provide the completeness and comparability those stakeholders require. Cash-based accounts would not give an accurate picture of liabilities outstanding.
Together, accrual accounting and accrued expenses form the backbone of financial reporting that stakeholders, lenders, and regulators can genuinely trust.
How to Record Accrued Expenses in Your Books
Accrued expenses are recorded using double-entry bookkeeping, the fundamental system of accounting in which every transaction has two equal and opposite entries. Here is how the process works in practice.
Step 1: Record the Accrual at Period End
When you identify an expense that has been incurred but not yet billed or paid, you record it as follows:
Journal Entry, Recording an Accrual
| Account | Debit | Credit |
| Expense Account (e.g. Wages Expense) | £X | |
| Accrued Liabilities / Accruals | £X |
- Debit the relevant expense account, this increases the expense recognised in the period
- Credit the accrued liabilities account, this creates the liability on the balance sheet
Worked Example: Accrued Wages
A business has a monthly payroll of £18,000. The accounting period ends on 31 March, but wages for the final week (£4,500) will not be paid until 5 April.
At 31 March:
| Account | Debit | Credit |
| Wages Expense | £4,500 | |
| Accrued Liabilities | £4,500 |
This records the cost in March, where it belongs, and creates a liability showing money owed to employees.
Step 2: Reverse the Accrual in the Next Period
When the invoice arrives or payment is made in the following period, the accrual is reversed and the actual transaction recorded.
At 5 April (when wages are paid):
| Account | Debit | Credit |
| Accrued Liabilities | £4,500 | |
| Bank / Cash | £4,500 |
This clears the liability and records the actual cash payment. The net effect across both periods is correct, wages are expensed in March and the cash payment reduces the liability in April.
Step 3: Adjust for Differences
If the actual amount differs from the estimate, which happens frequently with utility bills or professional fees, the difference is adjusted when the invoice is received, either increasing or reducing the relevant expense.
Applying these entries consistently at every period end ensures your accounts reflect the true cost of running your business throughout the year.
Why Accrued Expenses Matter for Financial Reporting
Accrued expenses are not a minor bookkeeping detail, they have a direct and material impact on how a business’s financial position is presented and understood.
Impact on the Profit and Loss Account
Accrued expenses ensure that the correct costs are matched to the period in which they were incurred. Without them, profit figures for any given period would be incomplete and unreliable, potentially overstating earnings and misleading stakeholders.
Impact on the Balance Sheet
Every accrued expense creates a corresponding liability. A balance sheet that omits accruals understates liabilities and overstates net assets, misrepresenting the true financial position of the business.
Impact on Tax Reporting
HMRC requires that business accounts submitted for Corporation Tax purposes are prepared on an accruals basis. Expenses incurred in the accounting period, even if unpaid, are generally deductible in that period, provided they meet the conditions for tax relief. Missing accruals could mean overpaying tax.
Impact on Audit and Compliance
For businesses subject to statutory audit, accrued expenses are an area of particular scrutiny. Auditors test whether accruals are complete, reasonably estimated, and properly reversed in the subsequent period. Inaccurate or missing accruals can result in qualified audit opinions.
Impact on Investor and Lender Confidence
Anyone assessing a business for lending or investment purposes will scrutinise the quality of its accounting. A company that consistently records accruals accurately demonstrates financial discipline and transparency, qualities that build external confidence.
he quality of your accruals directly determines whether your financial statements present a fair and accurate view of business performance.
Common Mistakes When Recording Accrued Expenses
Even experienced finance teams make errors with accruals. These are the most frequent mistakes, and the practical steps to prevent them.
- Forgetting to accrue recurring expenses at period end: Utilities, wages, and interest are incurred every period, yet they are regularly missed at month-end closes. Fix this by creating a standing accruals checklist that is reviewed before every period close, covering all predictable recurring costs.
- Using inaccurate estimates: Accruals often require estimation, but poor estimates create distortions that carry through the accounts. Review prior period accruals against actual invoices received to calibrate the accuracy of your estimates over time.
- Failing to reverse accruals in the following period: If an accrual is not reversed when the actual invoice arrives, the cost is double-counted, once as the accrual and again as the payable. Use auto-reversing journal entries in your accounting software to prevent this automatically.
- Posting accruals to the wrong expense account: An accrual posted to the wrong nominal code distorts cost analysis and departmental reporting. Always match the accrual to the same expense code that the actual invoice will be posted to.
- Not documenting the basis for accrual estimates: Accruals require judgement. Without documentation, auditors and finance team members cannot verify or challenge the assumptions made. Maintain a simple accruals schedule, a spreadsheet or software report detailing each accrual, its basis, and the expected invoice date.
- Accruing for costs that do not meet the recognition criteria: Not all anticipated costs should be accrued. A cost should only be accrued if the obligation has actually been incurred during the period, not merely expected. Accruing for costs that relate to future periods overstates current liabilities and understates future expenses.
- Inconsistent treatment across periods: Applying different accrual policies in different periods makes financial statements incomparable and may raise red flags during audit. Establish clear, written accruals policies and apply them consistently, period after period.
Building consistent habits and clear internal policies around accruals will eliminate most of these errors before they ever reach your accounts.
Final Thoughts
Accrued expenses and accrual accounting are not just technical accounting requirements, they are the foundation of reliable, meaningful financial reporting. When costs are matched to the period they belong to, profit figures become trustworthy, balance sheets reflect genuine obligations, and decision-makers have the accurate data they need.
Whether you are preparing monthly management accounts, statutory financial statements, or a Corporation Tax return, getting your accruals right is non-negotiable. Build consistent habits, document your estimates, and let your accounts tell the true financial story of your business.
FAQs
What Is An Accrued Expense In Simple Terms?
An accrued expense is a cost your business has incurred during an accounting period but has not yet paid or been invoiced for. It is recorded as a liability at the period end to ensure the cost appears in the correct period’s accounts, regardless of when cash actually leaves the business.
Are Accrued Expenses The Same As Accounts Payable?
No, they are similar but distinct. Accounts payable are liabilities where a supplier invoice has been received but not yet paid. Accrued expenses are liabilities where no invoice has yet been received, the cost is estimated and recorded based on the obligation created. When the invoice arrives, the accrual is typically reversed and replaced with the accounts payable entry.
How Are Accrued Expenses Recorded In Double-Entry Bookkeeping?
An accrued expense is recorded by debiting the relevant expense account, which increases the cost in the profit and loss account, and crediting the accrued liabilities account, which creates the liability on the balance sheet. When the actual payment is made or invoice received, the accrued liability is debited to clear it, and the bank or accounts payable account is credited.
Do Accrued Expenses Affect Cash Flow?
Not directly, accrued expenses are non-cash entries. They affect the profit and loss account and balance sheet but do not immediately impact cash. Cash is only affected when payment is actually made. This is why cash flow statements prepared under the indirect method add back changes in accruals to reconcile profit to cash generated from operations.
Is Accrual Accounting Mandatory In The UK?
Yes, for most businesses. Limited companies, LLPs, and VAT-registered businesses using standard accounting are required to use the accruals basis. Sole traders may use cash basis accounting for Self Assessment purposes if their annual turnover is below £150,000, but accrual accounting remains the more accurate and widely recommended approach for any business with meaningful complexity.
What Happens If Accruals Are Not Reversed In The Next Period?
If an accrual is not reversed when the actual invoice is received and posted, the expense will be recorded twice, once as the original accrual and again as the accounts payable entry. This double-counting overstates costs, understates profit, and creates an inaccurate balance sheet. Auto-reversing journal entries in accounting software prevents this from happening automatically.
Can Accrued Expenses Be Deducted For Tax Purposes?
Generally, yes, provided the expense was genuinely incurred in the accounting period and meets HMRC’s conditions for deductibility. Expenses that are accrued but lack sufficient certainty, such as vague provisions for future costs, may not qualify for tax deduction until the liability is confirmed. Always consult a qualified tax adviser for guidance on specific deductions.
What Is The Difference Between An Accrual And A Prepayment?
An accrual recognises a cost incurred in the current period that has not yet been paid, it creates a liability. A prepayment recognises a cost that has been paid in the current period but relates to a future period, it creates an asset (a prepaid expense). Both are adjustments made under accrual accounting to ensure costs appear in the correct period.
