What Cash and Accrual Accounting Actually Mean
The difference between cash and accrual accounting comes down to timing: when do you record a sale or an expense in your books?
Under the cash basis, you record income only when money actually lands in your bank account or cash drawer, and you record an expense only when you actually pay it. Under the accrual basis, you record income when you earn it — typically when you deliver the goods or complete the service and issue the invoice or official receipt — regardless of when the customer actually pays. Expenses are recorded when you incur them, not when cash leaves your account.
Consider a small design studio in Cebu that finishes a ₱120,000 project on June 20, 2026 and bills the client the same day, but the client only pays on July 15. Under cash accounting, that ₱120,000 is July income. Under accrual accounting, it is June income, and on June 20 the studio also records a ₱120,000 receivable that gets cleared when the cash comes in. Neither method changes the total amount the business eventually earns — only which month or which tax period it falls into.
What the BIR Expects: Books, Tax Basis, and VAT
The Tax Code allows both methods for income tax purposes, but the choice is not entirely free. Under Section 43 of the National Internal Revenue Code, the accounting method used for tax reporting must clearly reflect income, and the Bureau of Internal Revenue can require a taxpayer to change methods if the one being used distorts income — most commonly when a business carries inventory. If your business buys and sells goods (a retail store, a trading business, a small manufacturer), the BIR generally expects you to account for purchases, cost of sales, and merchandise on an accrual basis, even if you otherwise report cash received and cash paid for other transactions. Pure service providers and professionals — bookkeepers, consultants, freelancers — have more flexibility to use straight cash basis if it fairly reflects their income.
Value-added tax has its own timing rule that does not automatically follow your income tax method. Output VAT on the sale of services is generally due when payment is received, while output VAT on the sale of goods is due upon sale or delivery of the goods regardless of payment. This means a VAT-registered business can still be on cash-basis income tax reporting while its VAT obligations follow the VAT law's own timing.
A few registration and threshold figures matter here, and because these are set by law and can be adjusted, you should reconfirm the current amounts on the BIR website before relying on them:
- The VAT registration threshold is gross annual sales or receipts of ₱3,000,000. Cross this and you are required to register as a VAT taxpayer regardless of your accounting method.
- Under the Ease of Paying Taxes Act (RA 11976), the old ₱500 annual registration fee (BIR Form 0605) has been removed, and BIR-registered businesses no longer need to pay it every January.
- Late filing or late payment of a return generally carries a 25% surcharge (50% in cases of fraud or willful failure to file) plus 12% annual interest on the unpaid tax, computed from the deadline until fully paid.
Books of Accounts and Financial Statements
For financial reporting purposes — the statements you or your accountant prepare for the SEC, banks, or investors — the rule is stricter. Corporations, partnerships, and other entities that file audited financial statements under Philippine Financial Reporting Standards (PFRS) or PFRS for Small Entities must use the accrual basis. Cash-basis statements do not comply with PFRS and are generally not accepted for SEC filing of audited financial statements. So even a sole proprietor who reports income tax on a cash basis may still need accrual-based books if the business later incorporates or needs bank financing that requires PFRS-compliant statements.
How Your Method Affects Income Tax and Financial Statements
Because cash and accrual accounting can shift income between periods, they can shift how much tax is due in a given year — though not how much is due over the life of the business. Take a sole proprietor bookkeeper registered as a non-VAT taxpayer with gross receipts under ₱3,000,000, who has elected the graduated income tax rates rather than the 8% flat tax option.
Suppose she completes ₱850,000 worth of billable work in 2026, of which ₱700,000 is collected within the year and ₱150,000 remains uncollected as of December 31. Under the cash basis, only ₱700,000 counts as 2026 taxable revenue; the remaining ₱150,000 becomes 2027 income once collected. Under the accrual basis, the full ₱850,000 is 2026 income, and the ₱150,000 is simply an accounts receivable on the balance sheet.
Using the TRAIN law's graduated table for individuals (income over ₱800,000 up to ₱2,000,000 is taxed at ₱102,500 plus 25% of the excess over ₱800,000, after allowable deductions), reporting ₱850,000 versus ₱700,000 in taxable net income for the year produces a materially different tax due for 2026, with the difference simply deferred rather than eliminated — the ₱150,000 still gets taxed, just in the following year under cash accounting. This is exactly why the BIR does not let a business flip between methods freely: consistent application, chosen once and used until a valid reason exists to change, is what keeps taxable income comparable year to year and prevents deliberate income deferral.
Cash vs Accrual: Which Fits Your Business
For a small sole proprietorship or freelance practice with simple, mostly cash-collected transactions and no inventory, cash-basis accounting is usually easier to maintain and easier to explain to a bookkeeper who is not yet comfortable with receivables and payables. It also has the practical benefit of only taxing money you have actually received, which can help cash flow planning.
For any business that carries inventory, extends credit terms to customers, takes supplier credit, or is VAT-registered, accrual accounting gives a far more accurate picture of profitability and is generally what the BIR expects for that portion of the business involving goods. It is also the only option once you need PFRS-compliant statements for SEC filing, a bank loan application, or investor due diligence. Many growing businesses end up running a hybrid approach in practice — accrual for inventory and receivables, closer to cash for smaller incidental transactions — which is one reason the bookkeeping gets complex quickly once volume grows.
This is where the accounting method stops being a once-a-year decision and becomes a daily bookkeeping habit. Every invoice issued on credit, every supplier bill received before payment, and every collection against an old receivable needs to be recorded at the right point in time, consistently, for the method to actually work. In Kontabler, an invoice issued to a customer is posted to your books automatically the moment it is created, with the corresponding receivable and revenue entries recorded under accrual rules — so you are not manually deciding, transaction by transaction, whether something belongs in this month or the next.
Switching Methods and Staying Consistent
Once you adopt an accounting method for tax purposes, you are expected to use it consistently in succeeding years. Changing from cash to accrual, or vice versa, generally requires prior BIR approval, since a change in method affects the timing of taxable income and the BIR wants to confirm the change is not simply a way to defer or accelerate tax due. In practice, most small businesses that outgrow the cash basis do so naturally when they cross the VAT threshold, take on inventory, or need audited financial statements — at which point accrual becomes close to mandatory rather than optional.
Whichever method applies to your business, the safest approach is to decide deliberately with your accountant early in the business's life, document the choice, and apply it the same way every period. Because thresholds, surcharge and interest rates, and filing rules are set by law and adjusted periodically, always reconfirm the current figures on the BIR website or with your accountant before filing, rather than relying on numbers from a prior year.
Frequently asked questions
Can a small business simply choose whichever accounting method it prefers?
To a large extent yes for tax purposes, but the method must clearly reflect income under Section 43 of the Tax Code, and the BIR can require accrual accounting for businesses with inventory. Once chosen, the method should be used consistently unless the BIR approves a change.
Does VAT follow the same timing as cash or accrual income tax?
Not automatically. Output VAT on services is generally due when payment is received, while VAT on goods is generally due upon sale or delivery regardless of payment, so VAT timing can differ from your income tax accounting method.
Do sole proprietors need to use accrual accounting?
Not necessarily for income tax if the business is a simple service business without inventory and cash basis fairly reflects income, but accrual becomes effectively required once the business needs PFRS-compliant financial statements, such as for a bank loan or SEC filing.
Does the accounting method change how much total tax a business pays?
No, it only changes the timing of when income is recognized and taxed. Cash and accrual accounting produce the same total taxable income over the life of the business, but can produce different tax due amounts in any single year.
