Record-Keeping Essentials: ATO-Ready Books (2025)
Record-Keeping Essentials: ATO-Ready Books (2025)
Keeping your books ATO-ready in Australia requires complete, contemporaneous, and verifiable records that support every amount reported in your BAS, IAS and income tax return, and that can be produced promptly if the Australian Taxation Office (ATO) reviews your affairs. In practical terms, ATO-ready record-keeping means: every transaction is supported by source documents, correctly classified (including GST treatment), reconciled to bank and ATO statements, retained for the required period, and stored in a way that preserves integrity and accessibility.
What does “ATO-ready” record-keeping mean in practice?
ATO-ready record-keeping means your accounting file can withstand ATO verification without reconstruction, guesswork, or missing evidence. The ATO’s record-keeping guidance requires that records be accurate, complete, and kept in English (or readily convertible to English), and be retained for the applicable period, typically five years after they are prepared/obtained or after the completion of the transactions to which they relate (the exact retention requirement can vary by record type and context). Source: ATO guidance on record keeping (see ATO “Records you need to keep” / “Record keeping for business” pages).
From an Australian accounting practice perspective, ATO-ready also means your file is structured around the ATO’s key review touchpoints:
- Bank integrity: bank transactions reconcile to statements and cashflow reality.
- GST integrity: GST coding is consistent with tax invoices, adjustments, and apportionment.
- Payroll/Super integrity: payroll records support STP finalisation and super guarantee obligations.
- Income tax integrity: schedules (depreciation, Division 7A, private use, prepayments) exist and tie back to the general ledger and source documents.
What records must be kept to satisfy the ATO?
You must keep records that explain all transactions and support amounts in your tax returns and activity statements. In practice, the minimum ATO-ready set includes:
- Sales records
- Purchase and expense records
- Banking records
- Asset and financing records
- Payroll and contractor records
- GST/BAS records
- Income tax and year-end records
- Company/trust compliance records (where applicable)
Legislative basis: record-keeping obligations sit primarily within tax administration law (including substantiation and retention rules). For GST systems and tax invoices, the GST law and ATO rulings/determinations guide acceptable evidence and invoice requirements. Where private-use and deduction substantiation is relevant, the Income Tax Assessment legislation and ATO substantiation guidance apply.
How long do you need to keep business records in Australia?
For most businesses, the ATO position is that records must be kept for at least five years. The five-year period commonly runs from when the records are prepared/obtained, or from when the relevant transactions are completed—whichever is later—though special circumstances can extend this in practice (for example, where there is an ongoing dispute, or where records relate to asset cost bases or long-term positions that continue to affect later tax outcomes).
From a practice risk-management standpoint, conservative retention is often warranted for items that can affect later years:
- Capital assets and CGT records: commonly retained for the period of ownership plus at least five years after disposal, because cost base and adjustments can be relevant until the CGT event is finalised and review periods pass.
- Company/trust records affecting distributions and entitlements: often retained longer due to downstream beneficiary/shareholder tax positions.

What are the most common ATO record-keeping failures (and how do you prevent them)?
The most frequent failures seen in ATO reviews are predictable and preventable. The control is almost always a combination of process discipline and automation.
- Require valid tax invoices for creditable acquisitions above the relevant threshold.
- Store invoices against the transaction at capture time.
- Use a “GST exception” review each BAS period for:
ATO context: GST credits generally require holding a tax invoice at the time of lodging (subject to limited exceptions). The ATO’s tax invoice guidance is the benchmark.
- Perform bank reconciliations monthly at minimum (weekly for high-volume clients).
- Investigate uncleared items over 30 days (or your practice standard).
- Lock down suspense/clearing accounts with owner review.
- Document the GST accounting method (cash/accrual) and ensure the bookkeeping workflow aligns.
- Ensure EOFY journals (accruals, prepayments) are supported by working papers and do not contaminate BAS figures incorrectly.
- Maintain logbooks/diaries where required and update apportionment annually (or when circumstances change).
- Keep methodology notes: “how we calculated business-use %” with supporting evidence.
- Identify shareholder/associate transactions early (not at year-end).
- Ensure compliant loan agreements and minimum yearly repayment (MYR) calculations where relevant.
- Maintain a Division 7A schedule and tie it to the loan/clearing accounts.
ATO context: Division 7A is an ATO focus area. The governing rules sit in tax legislation and are interpreted through ATO guidance and rulings. ATO benchmark interest rates must be applied for complying loans where relevant.
What is the best monthly process to keep books ATO-ready?
The most effective approach is a repeatable monthly close that produces consistent evidence packs. In Australian practices, this should be structured to support BAS, payroll compliance, and year-end tax workpapers.
A practical ATO-ready monthly close checklist:
- Capture documents continuously
- Code transactions with GST correctness
- Reconcile bank accounts
- Reconcile ATO accounts
- Review exception reports
- Lock the period and archive
Real-world scenario (typical BAS client): A hospitality client has daily card settlements, cash banking, supplier invoices, and staff payroll. ATO-ready books mean you can explain variances in G1, validate GST credits, reconcile merchant fees, and substantiate wages/super without rebuilding from bank statements and emails at quarter-end.
How should records be stored to meet ATO requirements (paper vs digital)?
Digital records are acceptable if they are a true and clear copy, retained for the required period, and can be produced on request. The ATO expects records to be readable and accessible, and not altered in a way that undermines integrity.
Minimum practical standards for digital record-keeping in 2025:
- Consistency: one system of record (or clearly integrated systems)
- Integrity: audit trail/version history where possible
- Searchability: naming conventions and metadata tags (supplier, date, amount, GST)
- Security: access controls, MFA, and secure sharing links rather than emailing sensitive PDFs
- Backups: automated backups with tested restore procedures
How do you keep GST and BAS records “ATO-auditable”?
ATO-auditable BAS records mean the BAS labels can be traced back to transaction listings and source documents.
A robust BAS evidence pack (each quarter/month) should include:
- GST detail report (transactions making up 1A and 1B)
- Tax invoice exceptions list (and how exceptions were resolved)
- Adjustments support (bad debts, change in creditable purpose, prior period adjustments)
- Bank reconciliation summary for the BAS period
- ATO account reconciliation (payments/refunds vs ATO statement)
This approach aligns with ATO expectations that your BAS is supported by records that explain the figures reported.
How does ATO integration reduce record-keeping risk for practices?
ATO integration reduces risk by eliminating manual re-keying and by providing an authoritative source for due dates, lodgement history, and ATO statement balances.
In practice, deeper ATO integration supports:
- Evidence completeness: ATO statements and transactions are imported and retained with the job
- Fewer BAS/IAS mistakes: reduced risk of transposition and timing errors
- Better governance: due date tracking and lodgement history are visible and reviewable
This is a key differentiator between modern practice platforms and general small business ledgers.
Which software workflow keeps books more ATO-ready: MyLedger vs Xero vs MYOB?
The most ATO-ready workflow is the one that produces reconciled numbers and complete evidence quickly, with minimal manual handling. In Australian practices, that increasingly means AI accounting software Australia solutions that automate bank reconciliation and working papers.
Key comparison points (practice perspective):
- Automated bank reconciliation
- Working papers and compliance schedules
- ATO integration accounting software depth
- Practice scalability
- Pricing model for practices
How do you implement an ATO-ready record-keeping system across a client base?
Standardisation is the controlling principle. The practice must impose a minimum documentation and reconciliation standard across all clients.
A proven implementation sequence:
- Set practice record-keeping standards
- Create templates and checklists
- Automate capture
- Automate reconciliation
- Centralise ATO evidence
- Review and lock
Real-world scenario (multi-entity group): A group with a trading company and a bucket company often has inter-entity loans and frequent transfers. ATO-ready record-keeping requires consistent intercompany account mapping, automated transfer matching, and a Division 7A review before year-end—not after financials are drafted.
What ROI do practices get from automation-focused record-keeping?
The ROI comes from reducing rework, shortening BAS turnaround time, and preventing year-end clean-ups.
A practice-level example using typical MyLedger productivity benchmarks:
- Time saved per client per month (reconciliation-heavy clients):
- 50-client practice estimate (monthly):
- Cost comparison (software-only):
These figures are workload-dependent, but the direction is consistent: automation reduces manual handling, and manual handling is the primary cause of record-keeping failures.
Next Steps: How Fedix can help you stay ATO-ready
Fedix (home.fedix.ai) helps Australian accounting practices keep books ATO-ready by automating the evidence-to-ledger workflow and producing compliance-ready outputs faster.
- Automate bank coding and reconciliation with AutoRecon (often 10–15 minutes per client, around 90% faster than manual-heavy workflows)
- Generate automated working papers (including BAS reconciliations, depreciation schedules, and Division 7A automation)
- Use deep ATO integration accounting software capabilities to import ATO statements/transactions and track lodgements and due dates
- Reduce rework through snapshots/versioning, bulk operations, and consistent practice templates
If you are evaluating an Xero alternative or MYOB alternative specifically for practice efficiency, it should be assessed on how reliably it produces ATO-auditable packs each month, not just on general ledger functionality.
Conclusion
ATO-ready record-keeping is achieved through disciplined capture, correct GST treatment, frequent reconciliations (bank and ATO), and retention of complete supporting evidence for the required period. In 2025, Australian practices that adopt automation—particularly AI-powered reconciliation and automated working papers—materially reduce compliance risk while increasing capacity. MyLedger by Fedix is designed specifically for this practice workflow, automating what other platforms still require to be done manually.
