Cash vs Accrual Rules
| Criterion | Cash Basis (Sole Traders / Small Business) | Accruals Basis |
|---|---|---|
| Eligibility | For income tax, use the method that correctly reflects income under TR 98/1; small-business status alone does not establish a receipts basis | Apply the appropriate income-tax method and separate financial-reporting requirements |
| Income recognised | When cash received | When earned (invoice raised or goods delivered) |
| Expenses recognised | When cash paid | When incurred (liability arises) |
| Trading stock | Eligible small business entities can use s 328-285 where the reasonably estimated stock-value change is $5,000 or less | Otherwise apply the required stock adjustments; this is separate from GST cash accounting |
| Prepaid expenses | Test the 12-month rule and other exceptions under ITAA 1936 ss 82KZL and 82KZM | Apply the relevant tax apportionment and financial-reporting rules separately |
Applies to reporting entities using Tier 1/Tier 2. Five-step model:
Small businesses using simplified reporting typically recognise on delivery/completion.

Every transaction needs four decisions, not one. Answer them in this order, because a later answer can change an earlier one.
au-rental-property.md for the repairs and improvements tests.Private use. Where an expense serves both business and private purposes, record the full amount and apportion, rather than guessing a net figure. The apportionment basis must be documented and consistent: a logbook for a vehicle, a floor area or hours record for a home office, an itemised bill for a phone. A percentage with no supporting method fails on review.
Unknown transactions. Post to a clearing or suspense account and list them for the client. Never guess a classification to close a period. An unresolved suspense balance at period end means the BAS and the accounts are both unreliable. See au-bas-preparation.md Section 4.
Evidence to hold
| Transaction | Evidence required |
|---|---|
| Sale | Invoice or point-of-sale record. A tax invoice where GST is charged |
| Purchase where a GST credit is claimed | A valid tax invoice, unless the acquisition is $82.50 including GST or less |
| Purchase with no GST credit | Sufficient record to show the expense was incurred and its purpose |
| Asset acquisition | Invoice, plus the date first used or installed ready for use |
| Asset disposal | Sale document, plus the written down value and any balancing adjustment |
| Vehicle expenses | Logbook for a continuous 12-week period, valid five years, plus odometer readings, or kilometre records for the cents per kilometre method |
| Home office | Hours record and evidence that the expenses were incurred |
| Payroll | Payroll register, timesheets, the employment record and STP submissions |
| Adjustment to a sale or purchase | Adjustment note or credit note |
| Bad debt written off | The board minute or file note recording the write-off and its date |
Records are generally kept for five years from lodgment, and longer where a CGT asset or a carried-forward loss depends on them.
A reconciliation is what makes the ledger evidence rather than assertion. At minimum, each period:
The ledger produces the financial statements. The tax return starts from those statements and then adjusts. Recording the tax answer in the ledger destroys the financial statements; recording only the accounting answer and forgetting the adjustment understates or overstates tax. Keep both, and keep the reconciliation between them.
Accounting treatment vs tax treatment
| Item | Accounting treatment | Tax treatment |
|---|---|---|
| Depreciation | Useful life and residual value under AASB 116 | Effective life under Division 40, the small business pool, or the instant asset write-off |
| Buildings and structural improvements | Cost or revaluation model under AASB 116, with depreciation and impairment where required under either model | Division 43 capital works at a fixed rate, and the deduction reduces the CGT cost base |
| Employee leave provisions | Recognised when the obligation arises | Deductible when the leave is paid |
| Doubtful debts allowance | An impairment estimate | Not deductible. Only a debt actually written off as bad is deductible |
| Entertainment | An expense in the profit and loss | Commonly non-deductible, and may instead be a fringe benefit |
| Fines and penalties | An expense | Not deductible |
| General interest charge on a tax debt | An expense | Not deductible where incurred on or after 1 July 2025 |
| Revenue | AASB 15 performance obligations | Derived when earned or received, depending on the accounting basis and the taxpayer |
| Prepayments | An asset, expensed over the period | Prepayment rules can spread the deduction, with a 12-month exception for some taxpayers |
| Borrowing costs | AASB 123 | Deductible over five years or the term of the loan, whichever is shorter |
| Unrealised foreign exchange movements | Revalued at reporting date | Taxed on a realisation event under Division 775 |
| Leases | Right-of-use asset and lease liability under AASB 16 | Depends on whether the arrangement is a lease or a hire purchase for tax |
Choosing the cost model does not remove depreciation: allocate the depreciable amount over the asset's useful life. Account for land separately from buildings. AASB 116 paras 29–31, 50, 58
Record permanent and temporary differences in a tax reconciliation working paper. A company also needs deferred tax balances where it reports under the full recognition requirements.
Where the error is found matters more than how large it is.
Correcting an error
| Where the error is | What to do |
|---|---|
| In the current open period, nothing lodged | Fix the transaction. No further action |
| In a closed period, but no BAS or return lodged | Post a dated correcting journal with a narration explaining it. Do not backdate into a locked period without a record |
| In a lodged BAS, GST affected | Apply the GST error correction rules. See au-bas-preparation.md Section 7 |
| In a lodged BAS, PAYG withholding affected | Correct through the PAYG withholding correction process, and check whether STP needs updating |
| In a lodged income tax return | Request an amendment. See au-lodgment-deadlines-penalties.md Section 10 |
| Circumstances changed after correct reporting | This is an adjustment, not an error. Record it in the current period |
Never fix a lodged period by silently re-opening it. The accounts must continue to agree with what was lodged, or to a documented correction of it. An unexplained change to a locked period is the difference between a correction and a misstatement.
