Australia is one of very few countries that lets individual investors recover the corporate tax already paid on their dividends — and even hands back cash refunds when those credits exceed the investor's own tax bill. This is the dividend imputation system, and the credits attached to franked dividends are called franking credits. This guide unpacks how the gross-up actually works, the 45-day holding rule that catches casual traders, and why retirees and SMSFs in pension phase often see their tax refund jump by thousands.
Why Australia is unusual
In most countries, company profits are taxed twice: once at the corporate level, then again as income tax when shareholders receive a dividend. Australia avoids this double taxation by imputing the corporate tax already paid back to the shareholder.
The Australian company tax rate is 30% for most listed companies, or 25% for *base rate entities* (typically smaller companies with passive income below 80%). When that company pays a fully franked dividend, the shareholder receives:
When the shareholder lodges their tax return, both amounts are added to assessable income (the "gross-up"), the tax is calculated at their marginal rate, and the franking credit is then applied as an offset. If credits exceed tax payable, the difference is refunded in cash. This refundability is the feature that makes Australia genuinely unusual — most other imputation countries (the UK, parts of Europe) capped or removed cash refunds long ago.
The gross-up formula
The core mechanic is simple but worth committing to memory.
For a fully franked dividend at the 30% company rate:
```
franking credit = cash dividend × (30 / 70)
grossed-up taxable amount = cash dividend + franking credit
```
Worked example. You receive a fully franked cash dividend of $700.
- Franking credit: $700 × (30 / 70) = $300
- Grossed-up taxable amount: $700 + $300 = $1,000
You declare $1,000 of dividend income on your return. Tax is calculated on the full $1,000 at your marginal rate, then the $300 franking credit reduces what you owe (or is refunded if you owe nothing).
For a base rate entity dividend at 25%, the formula becomes `cash × (25 / 75)`. Partially franked dividends (say 50% franked) carry a proportional credit.
| Dividend type | Cash dividend | Franking credit | Grossed-up amount |
|---|---|---|---|
| Fully franked (30%) | $700 | $300 | $1,000 |
| Fully franked (25%, BRE) | $750 | $250 | $1,000 |
| 50% franked (30%) | $850 | $150 | $1,000 |
| Unfranked | $1,000 | $0 | $1,000 |
AusTax AI tip: Always look at the grossed-up yield, not the headline cash yield. A 4% fully franked dividend is effectively a 5.71% pre-tax return — much higher than an unfranked 5% yield once you account for the credits.
How franking credits feel different at different tax rates
The credit is a fixed 30 cents per dollar of cash dividend. What changes is your marginal tax rate, which determines whether you owe additional tax or get a refund.
| Marginal rate | Tax on $1,000 grossed up | Less franking credit | Net result |
|---|---|---|---|
| 0% (low-income retiree) | $0 | -$300 | $300 refund |
| 16% | $160 | -$300 | $140 refund |
| 30% (matches company rate) | $300 | -$300 | $0 — neutral |
| 37% | $370 | -$300 | $70 to pay |
| 45% (top bracket) | $450 | -$300 | $150 to pay |
This is why low-marginal-rate investors love franked dividends: they not only avoid double tax, they actively receive cash from the ATO. SMSF in pension phase (taxed at 0%), retirees with assessable income below the tax-free threshold, and registered charities are the biggest beneficiaries.
The 45-day holding rule
The ATO does not let you cherry-pick dividend ex-dates by buying just before and selling just after. To claim franking credits, you generally must hold the shares "at risk" for at least 45 days, not counting the day you bought or sold.
"At risk" means you bear genuine ownership risk — no derivative hedge, no pre-arranged sale, no zero-collar option. Day-traders who flip shares around an ex-dividend date will fail this test, and their credits are denied (not just deferred).
The rule extends to 90 days for preference shares.
Small-shareholder exemption
Individual investors with $5,000 or less in total franking credits for the year are exempt from the 45-day rule. This carve-out keeps the ATO's auditing focus on serious dividend-stripping schemes, not retail investors with a balanced share portfolio.
The $5,000 threshold maps to roughly $11,667 in fully franked cash dividends ($5,000 × 70/30). Most retail investors with a single dividend-focused ETF or a basket of large-cap stocks fall comfortably under this ceiling.
If you cross the $5,000 line — for example by inheriting a parcel of bank shares — every credit on every parcel must satisfy the 45-day test, not just the credits above the threshold. So plan share trades carefully around tax year end.
AusTax AI tip: If your franking credits are climbing toward $5,000 because of a great year for ASX dividends, double-check the holding periods on every parcel before you submit the return. Auto-imported dividend feeds from CommSec or Sharesight do not flag potential 45-day failures for you.
Why the refund of excess credits matters
Unlike many other tax offsets, franking credits are refundable to individuals, super funds and charities. If your assessable tax liability is $0 and you have $4,000 of franking credits, the ATO writes you a cheque for $4,000.
This design is what attracts retirees in particular. A self-funded retiree with $50,000 of grossed-up dividend income, after using the tax-free threshold and the seniors and pensioners tax offset (SAPTO), often pays no income tax — and walks away with the franking credits as a cash refund. For an SMSF in pension phase, the result is even cleaner: the fund's tax rate on pension assets is 0%, so 100% of credits are refunded.
Brief political context
In 2019, federal Labor proposed removing the cash refund of excess franking credits, while keeping the offset against any tax owed. The proposal was unpopular with retirees and self-funded pensioners and contributed to Labor losing the election. The system as described in this article — full refundability — has been retained ever since. We mention this only as background; current rules are stable.
Common mistakes to avoid
Summary checklist
- Use the formula: franking credit = cash dividend × (30/70) for fully franked at 30%.
- Always declare the grossed-up amount, not just the cash, in your return.
- Hold shares at risk for 45 days (not counting buy/sell day) unless under the $5,000 small-shareholder carve-out.
- Low-income or 0%-rate investors (retirees, SMSF pension phase, charities) get excess credits refunded as cash.
- Distinguish 30% (most listed companies) from 25% (base rate entities) when computing the credit.
- Cross-check your broker tax statement against the ATO prefill — they should agree to the cent.
