How to Perform a Shariah Audit on Your Own Portfolio

For many Muslim Australians, building wealth through ethical investments feels rewarding until questions surface about what exactly sits inside a managed fund or superannuation account. A Shariah audit on your own portfolio is the process of methodically reviewing every holding, its financial ratios and its income sources against Islamic principles, then cleansing any impermissible earnings through purification. Whether your savings are held in a self-managed super fund in Parramatta, an industry fund in Melbourne or a direct share portfolio on the ASX, the same disciplined approach can be applied without needing a full external review. The exercise is less about perfection and more about sincere, well-documented intent.

The good news is that many of the tools required are already publicly available through the Australian Securities Exchange disclosures, fund fact sheets from local providers like Hejaz, and the global AAOIFI screening standards that most Islamic fund managers in Australia follow. With a cup of coffee on a quiet Sunday arvo, anyone willing to spend a couple of hours can run a meaningful review and identify the gaps that need attention.

What a Shariah Audit Actually Means for Your Portfolio

At its core, a Shariah audit is a structured self-examination that mirrors what an external Shariah adviser does for an Islamic fund, but scaled down for an individual investor. The audit covers three layers: the nature of the business activity, the financial ratios that measure debt and interest exposure, and the income that needs to be purified and given away as part of a broader cleansing practice that many Australian Muslims learn about through local community centres and mosques.

The activity screen asks whether the underlying company is engaged in prohibited sectors such as conventional banking, alcohol production, gambling operations, or pork-related industries. A typical Australian share portfolio might include holdings in the major banks, brewers or casinos that would fail this screen outright. The financial screen then applies quantitative thresholds, while the income screen determines how much of the dividend or distribution received must be donated to charity to cleanse the portfolio.

Running this exercise is valuable even for investors who believe their holdings are already compliant, because standards evolve and what was acceptable five years ago may no longer meet the line drawn by scholars sitting on local Shariah boards. Australian investors should remember that an annual review is a habit rather than a one-off chore, particularly as companies shift their revenue mix and refinance their balance sheets each year.

Mapping Your Holdings Against Screening Criteria

Begin by listing every investment on a single spreadsheet: shares held directly through a broker, exchange-traded funds, managed funds, and any property or private investments. For each line item, note the full company name, the industry classification under the ASX sector taxonomy, and the country of primary operations. Many local investors are surprised to discover how much of their superannuation is exposed to non-compliant sectors when the holdings are laid out side by side.

Once the list is complete, work through the activity screen for each holding. A quick rule of thumb used by several Islamic advisory firms in Sydney and Brisbane is to flag any business whose primary revenue comes from interest, gambling, alcohol, weapons, adult entertainment or pork. If the figure of a company like a major Australian bank or a hotel group that runs bars and gaming venues appears, it almost certainly fails this first screen.

For investors who hold mutual funds or exchange-traded funds, the analysis needs to go one level deeper, because the wrapper is not the same as the contents. Readers looking at managed products can find guidance on evaluating an Islamic mutual fund and how to look through to the underlying assets held inside.

Calculating Financial Ratios and Tolerable Thresholds

The second layer is quantitative and centres on the financial ratios most AAOIFI-compliant funds apply. Two key ratios are watched closely: total debt divided by total assets, and cash plus interest-bearing securities divided by total assets. AAOIFI's standard 21 generally sets the debt ratio threshold at thirty-three percent for investee companies, while the cash and interest-bearing securities ratio is commonly capped at thirty-three percent or sometimes forty-five percent depending on the scholar's interpretation.

For shares listed on the ASX, these ratios can usually be pulled from the most recent annual report lodged with ASIC, or from financial data providers that summarise balance sheet metrics. If you hold an international stock, the equivalent US filing or UK annual report will contain the same numbers. Take the time to calculate the trailing twelve-month figures rather than relying on older data, because ratios shift quickly, especially for property trusts that refinance regularly.

A useful approach for Australian investors is to build a simple ratio worksheet with a column for each holding, the two ratios calculated, and a pass or fail flag. Anything that breaches the threshold is a candidate for divestment, even if the underlying business activity is permissible. Some scholars permit a slightly higher debt ratio for highly capital-intensive industries such as utilities, but this is a judgement call best discussed with a qualified adviser rather than decided over a spreadsheet.

Reviewing Income Sources and Setting Up Records

Once the holdings have been screened and the ratios calculated, the next step is to track the income each holding generates throughout the financial year. Dividend payments, distributions from managed funds, and rental income from investment properties all need to be reviewed. For dividend-paying shares on the ASX, the dividend statement issued by the broker will show the franked and unfranked components, and any interest paid on cash balances within the brokerage account should be tracked separately as it is generally impure.

A common misunderstanding in Australia is that franking credits make a dividend more Shariah-compliant. They do not. Franking credits are a tax mechanism reflecting corporate tax already paid in Australia and have no bearing on the permissibility of the underlying earnings. Investors who decide to retain non-compliant holdings for practical reasons should still calculate the portion of income derived from interest or impermissible activities and arrange for that amount to be donated to eligible charitable causes without expecting a tax deduction.

Documents to Keep for Your Shariah Audit

Keeping these records not only supports the audit but also provides evidence of sincere effort should you ever wish to consult a Shariah adviser about grey areas. Most advisers appreciate seeing organised documentation far more than a verbal summary offered during the meeting.

A Side-by-Side Look at Screening Approaches

Not all Islamic screening methodologies produce the same outcome. Some funds use stricter activity filters that exclude any company deriving more than a small percentage of revenue from a prohibited line, while others apply more lenient quantitative thresholds. The comparison below sets out two commonly referenced approaches that Australian Muslim investors are likely to encounter when reviewing local and international funds.

Screen Criterion AAOIFI Standard 21 Approach Common Industry Practice
Debt-to-asset ratio Maximum 33% for investee companies Often 33%, sometimes up to 40% for property trusts
Cash and interest-bearing securities Maximum 33% of total assets Maximum 33% to 45% depending on the scholar
Activity exclusions Core business must be permissible Core plus significant revenue streams considered
Receivables threshold 33% of total assets cap Frequently omitted by mainstream index providers
Purification required Yes, on dividends and distributions Sometimes required, sometimes waived for index funds

The variation between approaches explains why two Islamic funds tracking similar strategies can hold slightly different portfolios. Understanding which methodology your own holdings rely on helps you decide whether the screening bar matches your personal convictions or the rulings of the scholars you follow.

Preparing for Your Next Review and Moving Forward

A self-conducted Shariah audit becomes more valuable when it is repeated regularly rather than performed once and forgotten. Setting a recurring calendar reminder in July, the middle of the financial reporting season in Australia, gives you access to the freshest annual reports before companies enter their quiet periods ahead of the August results cycle. Pairing this with a quick review of any new holdings added during the year keeps the audit current without becoming burdensome.

For investors who also own property, the same principles apply to the structure of the finance used to acquire a home. Avoiding interest entirely is achievable through several Shariah-compliant home finance products available from Australian providers, and anyone considering this transition can read more about buying a home interest-free to understand the practical mechanics involved.

Quick Steps Before Your Next Portfolio Review

When you feel ready to go further, exploring additional resources can deepen your understanding and point you towards advisers who work specifically with Muslim Australians. A great place to start is Ahmad Sanusi Husain's website, which collects practical articles on halal investing, ethical financial planning and the day-to-day decisions that shape a compliant portfolio. Treat the self-audit as a living practice, refine it each year, and trust that the effort itself carries reward.
