What Is Accrual Accounting? Definition and How It Works

Accrual accounting is a method of recording financial transactions when they are earned or incurred, not when the cash is actually received or paid.

This is the accrual accounting definition recognized under US GAAP and IFRS.

Under accrual basis accounting, if you complete a project in December but receive payment in January, the revenue is recorded in December. The income belongs to the period in which the work was performed, not the period in which the cash arrived.

The same principle applies to expenses. If you receive an invoice in December but pay it in January, the expense is recorded in December under accrual accounting.

According to the Financial Accounting Standards Board (FASB), accrual basis accounting provides a more accurate picture of a company’s financial position because it matches revenues with the expenses incurred to generate them. This is known as the matching principle and is the foundation of GAAP-compliant financial reporting.

Core Components of Accrual Accounting

• Accounts receivable: revenue earned but not yet collected in cash. Accrual accounting tracks what customers owe the business at any point in time.
• Accounts payable: expenses incurred but not yet paid. Accrual accounting captures obligations the business has to suppliers and vendors.
• Deferred revenue: cash received before the service or product is delivered. Under accrual basis accounting, this is a liability until the obligation is fulfilled.
• Accrued expenses: costs incurred in one period but paid in a later period, such as wages earned by employees but not yet paid at month end.
• Prepaid expenses: cash paid in advance for a future benefit, such as an annual insurance premium. Accrual accounting spreads the expense across the periods it covers.

What Is Accrual Accounting Used For?

Accrual accounting is used by any business that needs GAAP-compliant financial statements, seeks external financing, has investors or shareholders, or operates across multiple accounting periods with revenue and costs that do not align with cash timing.

It is required for all publicly traded companies and is the standard method for any business preparing audited financial statements. Businesses that use accrual accounting also need accurate invoices, bills, reconciliations, and month-end records. Professional accounting and bookkeeping services help maintain those records and support reliable financial reporting.

What Is Cash Basis Accounting and When Does It Apply?

Cash basis accounting records revenue when cash is received and expenses when cash is paid. It does not track accounts receivable, accounts payable, or accrued liabilities.

Cash basis accounting is straightforward. There are no adjusting entries, no receivables to track, and no deferred revenue calculations. What comes in and what goes out is what gets recorded.

The IRS permits cash basis accounting for businesses with average annual gross receipts of $25 million or less over the prior three tax years, under the Tax Cuts and Jobs Act of 2018.

For very small businesses, sole proprietors, and freelancers with simple finances, cash basis accounting is often sufficient. It is easy to maintain, requires less accounting expertise, and gives a clear picture of actual cash availability at any point in time.

Where Cash Basis Accounting Falls Short

• Distorted profitability: a business can appear highly profitable in one month because several large payments arrived, and unprofitable the next even though operations were identical. Cash timing drives the numbers, not business performance.
• No visibility into receivables or payables: cash basis accounting does not track what customers owe or what the business owes suppliers, creating blind spots in financial planning.
• Not GAAP compliant: banks, investors, and many lenders require GAAP-compliant financial statements. Cash basis financials do not meet this standard, which limits financing options.
• Cannot support audit or review: auditors work from accrual basis records. A business on cash basis accounting that needs audited statements must convert its books before an audit can be performed.

What Is the Difference Between Cash and Accrual Accounting?

The core difference between cash and accrual accounting is timing. Accrual accounting records transactions when they occur economically. Cash basis accounting records them when cash physically moves.

This timing difference creates significantly different financial pictures for the same business in the same period.

Consider a business that completes $80,000 of work in Q4 but receives all payments in Q1. Under accrual accounting, $80,000 of revenue appears in Q4. Under cash basis accounting, Q4 shows zero revenue and Q1 shows $80,000, even though the work happened entirely in Q4.

According to the AICPA, this timing difference is the most common source of confusion when business owners review their financial statements and find that profit and cash do not match.

Accrual vs Cash Accounting: Side-by-Side Example

Scenario	Accrual Accounting	Cash Basis Accounting
Invoice $10,000 in December, paid in January	Record $10,000 revenue in December	Record $10,000 revenue in January
Receive $5,000 bill in December, pay in January	Record $5,000 expense in December	Record $5,000 expense in January
Receive $12,000 annual retainer upfront in January	Record $1,000/month across 12 months	Record full $12,000 in January
Pay $6,000 annual insurance premium in January	Record $500/month across 12 months	Record full $6,000 in January
December profit reported	Reflects actual work performed	Reflects only cash received/paid

How the Difference Affects Tax Liability

The accounting method cash or accrual you choose directly affects when income and deductions appear on your tax return.

Under cash basis accounting, you can defer income by delaying invoices until the next tax year, or accelerate deductions by prepaying expenses before year end. This gives small businesses a degree of tax timing flexibility.

Under accrual accounting, income is taxable when earned, not when received. You may owe tax on revenue that has not yet been collected in cash. However, you can also deduct expenses when incurred, even before they are paid.

According to the IRS, businesses that switch from cash to accrual accounting must file Form 3115 (Application for Change in Accounting Method) and may need to make a Section 481(a) adjustment to prevent income or deductions from being counted twice or missed entirely.

Accrual Accounting vs Cash Accounting: Which Method Is Right for Your Business?

The right accounting method depends on your business size, revenue, financing needs, and growth plans. For most growing businesses, accrual basis accounting is the more appropriate long-term choice.

Cash basis accounting works well when transactions are simple, revenue is received promptly, and the business has no plans to seek external financing or produce GAAP-compliant statements.

Accrual accounting is necessary when the business carries accounts receivable or payable for extended periods, applies for loans or lines of credit, has investors or shareholders, is preparing for an audit, or is approaching the IRS $25 million gross receipts threshold.

Decision Framework: Accounting Method Cash or Accrual

Business Situation	Recommended Method	Primary Reason
Solo / freelancer under $250K revenue	Cash basis accounting	Simple finances, no receivables complexity
Small business under $1M, no financing needs	Cash basis accounting	Easier to maintain, IRS permitted
Small business $1M to $5M, seeking financing	Accrual accounting	Lenders require GAAP-compliant statements
Business with significant receivables or payables	Accrual basis accounting	Cash basis will distort financial picture
Business with investors or shareholders	Accrual accounting	Investors require GAAP financials
Business preparing for audit or acquisition	Accrual basis accounting	Audits and due diligence require accrual basis
Business above IRS $25M gross receipts threshold	Accrual accounting	Required by IRS, no choice permitted
Nonprofit or publicly traded company	Accrual accounting	Mandatory under GAAP and regulatory requirements

What Lenders and Investors Expect

Most lenders, including commercial banks, SBA lenders, and private credit providers, require accrual basis financial statements when evaluating a loan application.

Investors expect GAAP-compliant financials, which means accrual accounting. A business presenting cash basis statements to a potential investor or acquirer will typically be asked to restate its financials before due diligence can proceed.

According to the Federal Reserve’s Small Business Credit Survey, over 40% of SMB loan rejections cite gaps in financial reporting as a contributing factor. Switching to accrual accounting before applying for financing removes one of the most common barriers to credit access.

How to Implement Accrual Basis Accounting in Your Business

Transitioning to accrual basis accounting requires updating your chart of accounts, establishing receivables and payables tracking, and adjusting how revenue and expenses are recognized.

For businesses currently on cash basis accounting, the switch to accrual accounting is a formal accounting method change that requires IRS notification and careful handling of the transition period.

According to the AICPA, the most common implementation challenges are correctly handling deferred revenue, identifying all accrued expenses at the transition date, and ensuring the prior period cash basis records are properly restated or reconciled.

Steps to Switch from Cash to Accrual Accounting

• File IRS Form 3115: notify the IRS of the accounting method change. A Section 481(a) adjustment is required to account for income and expenses that would otherwise be duplicated or missed during the transition period.
• Update your chart of accounts: add accounts receivable, accounts payable, deferred revenue, accrued expenses, and prepaid expenses to your general ledger.
• Establish a receivables process: record revenue when invoices are issued, not when payment arrives. Set up aging reports to track outstanding balances.
• Set up payables tracking: record expenses when bills are received. Track what the business owes suppliers at every month end.
• Implement month-end close procedures: accrual accounting requires monthly adjusting entries for accrued expenses, prepaid amortization, deferred revenue recognition, and depreciation.
• Update your accounting software: ensure your system is configured for accrual basis accounting. Most platforms including QuickBooks, Xero, and NetSuite support both methods but require correct setup to produce accurate accrual basis reports.

Accrual Accounting and Month-End Close

Accrual accounting requires a structured monthly close process. Revenue must be recognized in the correct period, expenses must be accrued before bills arrive, and balance sheet accounts must be reconciled.

Businesses that skip or rush the month-end close under accrual accounting produce unreliable financial statements. This defeats the primary benefit of the method, which is an accurate and timely view of financial performance.

Common Mistakes Businesses Make When Choosing Between Accrual and Cash Accounting

Choosing the wrong accounting method, or applying the chosen method incorrectly, creates financial reporting problems that compound over time.

• Staying on cash basis accounting too long: businesses that delay switching to accrual accounting often discover the problem only when applying for financing or preparing for an acquisition, at which point restating multiple years of financials is expensive and time-consuming.
• Mixing cash and accrual treatments in the same period: recording some transactions on a cash basis and others on an accrual basis within the same reporting period violates accounting standards and produces meaningless financial statements.
• Not recognizing deferred revenue correctly: businesses that receive advance payments and record them as income immediately are overstating revenue under accrual accounting. Prepayments are liabilities until the service or product is delivered.
• Missing accrued expenses at period end: if wages, rent, or other expenses have been incurred but no invoice has arrived by month end, they must still be accrued. Missing these entries understates expenses and overstates profit.
• Failing to notify the IRS when switching methods: switching between cash and accrual accounting without filing Form 3115 is a compliance error that can result in penalties and adjustments during an IRS examination.
• Assuming cash basis is always simpler: for businesses with significant receivables, payables, or inventory, cash basis accounting can actually be harder to reconcile and explain than accrual accounting, because the numbers rarely match operational reality.

FAQs about Accrual vs Cash Accounting

What is the difference between cash and accrual accounting?

The difference between cash and accrual accounting is timing. Accrual accounting records revenue when earned and expenses when incurred. Cash basis accounting records both only when cash is received or paid.

Accrual accounting gives a more accurate picture of financial performance. Cash basis accounting is simpler but can distort profitability when revenue and cash timing do not align.

What is accrual accounting?

Accrual accounting is the method of recording financial transactions when they occur economically, not when cash changes hands.

It is the standard accounting method under GAAP and IFRS, required for publicly traded companies, and recommended for any business that seeks financing, has investors, or carries accounts receivable and payable.

What is the accrual accounting definition?

The accrual accounting definition is: a method of accounting in which revenues are recognized when earned and expenses are recognized when incurred, regardless of when cash is received or paid.

This definition is grounded in the matching principle, which requires that revenues and the expenses incurred to generate them be recorded in the same accounting period.

What is cash basis accounting?

Cash basis accounting is the method of recording revenue when cash is received and expenses when cash is paid.

It does not track accounts receivable or payable. It is simpler to maintain than accrual accounting and is permitted by the IRS for businesses with average gross receipts below $25 million.

Which accounting method, cash or accrual, is better for a small business?

For very small businesses with simple finances and no financing needs, cash basis accounting is often adequate. For businesses above $1M in revenue, carrying receivables, seeking loans, or planning to grow, accrual basis accounting is the better long-term choice.

Most accountants recommend transitioning to accrual accounting before the business reaches $2M to $5M in revenue to avoid a costly mid-growth restatement.

Is accrual accounting required by the IRS?

Yes, for businesses with average annual gross receipts exceeding $25 million over the prior three tax years, the IRS requires accrual accounting under the Tax Cuts and Jobs Act of 2018.

Businesses below this threshold may use cash basis accounting for tax purposes but may still need accrual accounting for financial reporting, lender requirements, or investor expectations.

What is accrual basis accounting vs cash basis accounting for tax purposes?

Under cash basis accounting, income is taxable when received and expenses are deductible when paid. Under accrual basis accounting, income is taxable when earned and expenses are deductible when incurred.

The accounting method cash or accrual you use for tax purposes directly affects when tax liability arises, which is why the choice has both compliance and cash flow implications.

How do you switch from cash to accrual accounting?

Switching from cash to accrual accounting requires filing IRS Form 3115 to request an accounting method change and making a Section 481(a) adjustment.

You also need to update your chart of accounts, establish receivables and payables tracking, and implement a month-end close process with adjusting entries. Most businesses work with a CPA to manage this transition correctly.

Does accrual accounting vs cash accounting affect financial statements differently?

Yes. Accrual accounting produces GAAP-compliant financial statements that reflect true financial performance. Cash basis accounting produces statements that reflect only cash movements, which can significantly misrepresent profitability and financial position.

Lenders, investors, and auditors rely on accrual basis financial statements. Cash basis statements are typically only appropriate for internal management use at very small companies.

Can a business use both cash and accrual accounting?

A business cannot use both cash and accrual accounting in the same set of financial statements. However, some businesses maintain cash basis books for internal simplicity and convert to accrual for external reporting or tax filing.

This dual approach adds complexity and cost. Most CPAs recommend committing to accrual basis accounting as the primary method once a business reaches the scale where GAAP reporting is relevant.

Final Thoughts

Choosing between accrual and cash accounting is one of the most consequential financial decisions a business makes early in its life.

Cash basis accounting offers simplicity. Accrual accounting offers accuracy. For businesses that want to grow, raise capital, or simply understand whether they are actually profitable, accrual basis accounting is the more reliable foundation.
