An SMSF with frequent trades can produce hundreds of confirmations, settlements and cash movements in one year. Your audit preparation job is to turn that activity into one connected set of records. The closing broker holdings must agree with the accounts, and every cash movement needs an explanation.
Every SMSF needs an annual financial and compliance audit, even if the fund made no contributions or benefit payments. Trustees must appoint an approved, independent SMSF auditor at least 45 days before the annual return is due. The ATO's SMSF audit guidance explains those duties and the 45-day rule.
This guide helps you prepare the trading evidence. Your accountant prepares the accounts and tax work. Your auditor independently tests the financial statements and the fund's compliance with super law. A trading journal can support their work, but it cannot certify compliance.
Build one evidence pack
Create a folder for the financial year, then use the same sections each year. A useful pack contains:
- the fund's bank statements for the full year
- statements for every broker and cash account
- contract notes or trade confirmations for buys and sells
- dividend, distribution and foreign withholding statements
- corporate action documents, including splits, takeovers and returns of capital
- contribution, rollover, pension and benefit-payment records
- the investment strategy and minutes showing its review
- the year-end portfolio valuation and evidence supporting each price
- the parcel-level CGT workpaper prepared for the fund's tax records
- explanations and documents for transfers between accounts
Keep source documents as well as summaries. A spreadsheet total does not show the auditor which confirmation, dividend statement or bank entry supports the number.
If you also need to organise disposals for tax, use the Australian shares CGT tracking guide. It explains parcel history and cost-base records in more detail.
Reconcile the records in three directions
A clean audit pack connects holdings, cash and income. Work through each direction before sending the file.
1. Holdings to trade history
Start with the broker's 30 June holdings. For each security, calculate opening units plus purchases, less sales and other changes. The result should equal the closing units.
Suppose the fund opened with 800 shares in fictional RIVR.AU. It bought 300, sold 450 and received no corporate action. The expected closing holding is 650 shares. If the broker statement shows 700, find the missing 50-share movement before the auditor has to ask.
Check each parcel's acquisition date, quantity, price, brokerage and disposal allocation. Partial sales often expose errors because a broker's position summary may not show which tax parcel the trustee selected.
2. Broker cash to the bank account
Match deposits and withdrawals between the broker cash account and the SMSF bank account. Then explain the remaining broker cash movements with settlements, fees, dividends, interest or foreign exchange transactions.
Allow for settlement timing. A trade made near 30 June may appear in holdings before its cash settles. Record the trade date, settlement date and outstanding amount instead of forcing the bank balance to match too early.
3. Income to source statements
Reconcile dividends and distributions to issuer or registry statements. Record the gross amount, any franking credit, foreign tax withheld and the date paid. Do not treat the net bank deposit as the full tax record.
For foreign shares, retain the original currency amount and the exchange rate used for the AUD record. The foreign stock tax guide has an AUD conversion example and a record checklist.
Show how the trading fits the investment strategy
The auditor checks whether the trustees formulated, regularly reviewed and gave effect to the fund's investment strategy. A generic list of asset classes may raise questions when the fund makes frequent, concentrated trades.
Keep the strategy and the evidence of its review together. The file should show that trustees considered the fund's circumstances, including risk, likely return, liquidity, diversification and the ability to pay liabilities and benefits. Record material decisions in trustee minutes.
A journal can add context. For example, a note that a position closed after breaching a documented risk rule may help explain the commercial decision. It does not replace the broker confirmation, accounting record, investment strategy or trustee minute.
Use a four-stage preparation timeline
During the year
Download confirmations and statements before broker portals archive them. Record corporate actions when they happen. Review unmatched cash every month or quarter, while the transaction is still familiar.
Four to six weeks before 30 June
Review the investment strategy and expected liquidity. List assets that may need special valuation evidence. Ask the accountant which reports and file formats they want.
Soon after 30 June
Save final bank and broker statements. Capture year-end market values from reliable sources. Complete the holdings, cash and income reconciliations, then document any unresolved difference.
Before the annual return is due
Give the accountant a complete pack early enough for the accounts, tax work and independent audit. The fund cannot lodge its SMSF annual return until the audit is complete. Lodgment dates vary by fund and agent program, so confirm the actual date rather than relying on a date from an older article.
Questions to answer before handover
- Do closing units agree with opening units and every movement?
- Does each disposal have a traceable acquisition parcel and cost base?
- Can you explain every transfer between the SMSF bank and broker accounts?
- Have you recorded unsettled trades at year end?
- Do income records show gross income, credits and withholding?
- Are fund assets separate from personal assets and accounts?
- Does the investment strategy describe the fund's real approach?
- Are trustee decisions and the annual strategy review documented?
- Can the auditor open the files without needing access to your broker login?
SMSF trading audit FAQs
Is a broker annual tax statement enough?
Usually not by itself. The auditor may need statements, confirmations, bank evidence, income records and support for parcel calculations. Ask for the fund-specific list before handover.
Does the auditor prepare missing CGT calculations?
The auditor tests the financial report and compliance independently. Your accountant or tax agent normally prepares the accounts and tax workpapers. Giving the auditor incomplete records can delay both jobs.
What if holdings do not reconcile?
Do not hide the difference in a rounding adjustment. Trace corporate actions, transfers, unsettled trades and missing confirmations. Document any difference you cannot resolve and raise it with the accountant.
