The Franking Credits Trap: Why 5.7% Can Cost You $6,400 a Year 🇦🇺

▶

An Australian retiree with $800,000 in blue‑chip Australian shares yielding 4% fully franked dividends can be misled into thinking they’re “earning 5.7% tax‑free”, but if they are already in a 0% tax bracket the extra $3,429 in franking credit “refunds” is just their own tax money coming back, not free yield.

The number that matters

30% — company tax rate that sets the size of most franking credits in Australia (and the basis for the “extra yield” many investors think they’re getting), meaning every $70 cash dividend typically carries a $30 franking credit, grossing up the income by 43% on paper. (ATO, Vanguard, Parliamentary Budget Office; current framework)

How it quietly costs you

Mechanism: “Grossed‑up yield” framing makes franking credits look like extra investment return instead of a tax adjustment.

• Under the imputation system, a company that earns $100 profit pays $30 company tax at 30%, leaving $70 to pay as a franked dividend, plus a $30 franking credit that represents tax already paid.
• Investors are told to “gross up” their dividend: a $70 cash dividend + $30 franking credit = $100 assessable income, and marketing often presents this as a “5.7% grossed‑up yield” instead of a 4% cash yield with a tax credit attached.
• For someone on a 0% or 15% tax rate (common in super), the credit is mostly or entirely a refund of company tax, not an extra return generated by the fund manager.

Impact: comparing the wrong thing when choosing investments and funds.

Typical retail messaging:

• A fully‑franked 4% cash yield gets advertised as “5.7% grossed‑up yield” (4% / (1 – 0.30)).
• An unfranked 4.8% cash yield (e.g. from property or hybrids) is often shown as “4.8% yield”, no gross‑up.

If you are in a 0% tax environment (e.g. super in retirement phase):

• On $800,000 in Australian shares at 4% fully franked dividends, you receive $32,000 cash + $13,714 in franking credits (because (32,000 / 0.70 = 45,714), franking credit (= 13,714)).
• At a 0% personal tax rate, the ATO refunds the full $13,714 as a tax offset and then refund.
• Your real economic return before tax was still only 4% cash; the franking credit just reverses the 30% company tax that was already taken.

Compare that to an unfranked 4.8% yield:

• $800,000 × 4.8% = $38,400 cash, no franking credits.
• At 0% tax, you keep the full $38,400.
• The “5.7% grossed‑up” franked option produces $32,000 cash in your hand this year vs $38,400 cash from the unfranked option – that’s $6,400 less real spending money per year, even though the franked yield sounds higher.

Over 20 years of retirement (ignoring capital growth and compounding for simplicity), that framing can hide:

• $6,400 × 20 = $128,000 less cash received just from preferring a lower‑cash, franked yield that looked better on a grossed‑up basis. (Illustrative arithmetic, mechanism based on ATO/Vanguard description of franking.)

Old vs better comparison (super funds):

• The Association of Superannuation Funds of Australia notes that because fund tax rates (15% in accumulation, 0% in pension) are lower than the 30% company rate, franking credits often exceed the fund’s tax liability, generating refunds.
• A Financial Services Council submission using Treasury and Parliamentary Budget Office data found that in 2015–16, large super funds received $235 million of franking credit refunds, across 50 funds, averaging $4.7 million per fund, benefitting up to 2.6 million accounts.
• This demonstrates that a big slice of “outperformance from franking” is really tax recovery built into the system, not alpha.

Bottom line: the trap is comparing grossed‑up franked yields to unfranked cash yields and assuming the higher percentage equals higher real return, especially when your personal or super tax rate is already low.

The second, compounding trap

Mechanism: super and retirees overweight franked Australian shares for the “tax refund”, increasing concentration risk and potentially lowering long‑term net returns.

• ASFA notes that if franking credits became non‑refundable, the attractiveness of Australian equity would fall, and some equity price decline would be expected because a portion of franking credit value is already baked into share prices.
• Academic work cited by ASFA finds 17–70 cents in the dollar of franking credits is capitalised into share prices (Hathaway & Officer 2004), and another study finds about 50 cents per dollar.
• The Financial Services Council reports that franking credit refunds are “important to many Australians,” with over 80% of small APRA‑regulated funds receiving refunds in 2015–16, and for these funds the value of refunds increased yearly returns by up to 4.2% on average, with an average dollar benefit of $19,100 in 2015–16.

This leads many retirees/SMSFs to:

• Overweight Australian equities at the expense of global diversification, fixed income and other assets, purely to “harvest” franking credits.
• Underestimate the risk that policy changes (for example, prior proposals to remove cash refunds for some investors, described by one accountant as “a tax on a tax refund”) or share price adjustments could erode the apparent advantage.

Quantified long‑run cost of the distortion:

Consider two simple portfolios inside an SMSF in pension phase (0% tax):

• Portfolio A: 100% Australian shares, 4% fully franked cash yield; ignore capital growth and assume franking fully refunded.
• Portfolio B: 50% Australian shares (4% fully franked) + 50% global shares or diversified unfranked assets yielding 5% cash.

Annual cash for Portfolio A on $1,000,000:

• Cash dividends: $40,000 (4% of $1,000,000).
• Franking credit: (40,000 / 0.70 = 57,143) assessable → $17,143 franking credit.
• At 0% tax, you get $17,143 refund, but your spendable cash this year is still $40,000; the refund just reverses company tax.

Annual cash for Portfolio B:

• Australian shares half: $500,000 × 4% = $20,000 cash, plus $8,571 franking credit refunded.
• Global/unfranked half: $500,000 × 5% = $25,000 cash.
• Total cash received in the year: $45,000 (20,000 + 25,000), plus a refund of $8,571 (again, reversing company tax) for $45,000 of real investment cash vs $40,000 in Portfolio A, a $5,000 per year difference.

Over a 25‑year retirement, ignoring growth:

• $5,000 × 25 = $125,000 in extra cash from the more diversified portfolio.

Yet many SMSFs pick something like Portfolio A because “franking boosts my yield” and marketing focuses on “grossed‑up income” and “4–5% tax‑free income from Aussie shares” rather than the risk and opportunity cost.

ASFA also notes that if franking credits became non‑refundable:

• Tax on dividend income for those on 0% or 15% rates, including super members and low‑ to middle‑income earners, would increase, and
• The relative attractiveness of debt vs equity would change, affecting prices and long‑term returns.

An investor who is heavily concentrated in franked Australian shares because of franking may therefore be:

• Taking more concentration risk than they realise.
• Leaving tens or hundreds of thousands of dollars on the table compared with a more balanced portfolio with higher underlying cash yield, even before any policy risk materialises.

What this looks like in practice

Persona

• Name: Janet
• Age: 63
• Job: retiring nurse
• Income pre‑retirement: $85,000 salary
• Super: $900,000 in an industry super fund, mainly Australian shares option
• Phase: moving to account‑based pension (0% tax on earnings)
• Years to retirement horizon: 25 years

Discovery 1 — The “extra” 1.7% isn’t free money

Janet’s fund literature tells her the Australian shares option delivers “around 4% yield, or 5.7% grossed‑up including franking” (typical framing using the 30% company tax rate).

• On $900,000, that sounds like $51,300 of income (5.7%), but:
• Actual cash dividends at 4% are $36,000.
• The franking credit is (36,000 / 0.70 = 51,429) assessable, so $15,429 franking credit.
• At a 0% pension tax rate, the ATO refunds $15,429, but ASFA points out this occurs because the fund’s tax rate is lower than the 30% company rate, so credits exceed the fund’s tax liability and are refunded.
• Janet realises the 1.7 percentage points of “extra yield” is just a tax adjustment, not extra return her fund has magically created.

Discovery 2 — A balanced income option could pay her ~$9,000 more cash per year

Janet compares her current option to a hypothetical “balanced income” option:

• Current option: 90% Australian equities at 4% fully franked, 10% cash at 2%, inside a 0% pension fund.
• Equities cash: $900,000 × 90% × 4% = $32,400.
• Cash account: $900,000 × 10% × 2% = $1,800.
• Total cash yield: $34,200.
• Alternative: 50% Australian shares (4% fully franked), 50% diversified unfranked assets yielding 5%.
• Aussie shares: $900,000 × 50% × 4% = $18,000 cash.
• Other assets: $900,000 × 50% × 5% = $22,500 cash.
• Total cash: $40,500.

The difference is $6,300 more cash per year ($40,500 – $34,200), even before considering franking credits (which are simply tax reversals).

Over a 25‑year retirement, ignoring compounding:

• Janet could receive $6,300 × 25 = $157,500 more in cash income from the better‑balanced option.

Discovery 3 — “Bonus” franking refunds mask concentration risk

From industry data:

• The FSC notes that in 2015–16, refunds to large super funds totalled $235 million, with an average of $4.7 million per fund, benefitting up to 2.6 million accounts.
• For small APRA‑regulated funds, refunds increased yearly returns by up to 4.2% on average, with an average dollar benefit of $19,100 in 2015–16.

Janet’s fund reports a 1% per‑year outperformance vs peers, with materials highlighting their “franking advantage”. She realises:

• Part of that “outperformance” is the same kind of franking refund described by FSC and ASFA, available to many funds at similar tax rates.
• She is more concentrated in Australian shares than the typical diversified super option, which exposes her to domestic market and policy risk that may not be adequately compensated once you strip out the tax mechanics.

The full cost of doing nothing

Using Janet’s situation:

• Problem 1 cost (mis‑framed yield):
• She stays in an Aussie‑heavy option yielding $34,200 cash per year instead of a balanced option yielding $40,500 cash per year, a $6,300 annual shortfall.
• Problem 2 cost (concentration & missed diversification):
• Assume the diversified option’s underlying investments earn 1% higher total return per year over 25 years because of better diversification (a conservative difference consistent with the idea that franking refunds are not true alpha but tax recovery).
• On $900,000, a 1% annual return gap over 25 years implies roughly $900,000 × (1.01^25 – 1) ≈ $290,000 of extra capital in the diversified option (illustrative compounding based on 1% p.a. differential).

Combining lower annual cash and lower capital growth over 25 years, the total impact is on the order of:

• ~$150,000–$160,000 in lost cash income (based on $6,300 × 25 years).
• ~$290,000 in lost capital due to lower underlying returns from poor diversification.

Headline figure: around $400,000–$450,000 in lifetime impact for someone like Janet, purely from:

• Treating franking credits as “extra yield” rather than tax.
• Overweighting franked Australian shares and under‑diversifying.

What to do about it

1. Re‑label your dividends: separate cash yield from franking credits

1. Action: Calculate your true cash yield vs grossed‑up yield on Australian shares.
2. Tool/portal:

• Use the ATO online services via myGov to view your dividend and franking credit amounts in your tax return pre‑fill (items for dividends and franking credits).

3. Steps:

• Log into myGov → ATO online → Tax → Lodgments → Income tax → Income statements and reports → Dividends.
• Note the cash dividend amount and the franking credit amount separately.
• Compute your cash yield: cash dividends ÷ portfolio value; then see that the franking credit is a tax offset, not extra investment return.

4. What “good” looks like:

• You think about your portfolio yield primarily in terms of cash actually paid by companies or funds, with franking credits treated as tax adjustments when comparing investment options.

2. Check your super’s diversification beyond franked Aussie shares

1. Action: Review how heavily your super is allocated to Australian shares and what implicit bet you’re taking on franking credits.
2. Tool/portal:

• Use your super fund’s online portal and the government’s YourSuper comparison tool on the ATO website to compare the asset allocation and 10‑year returns of different MySuper products.

3. Steps:

• Log into your super fund’s portal, download the latest investment option fact sheet and note the percentage in Australian shares vs global shares, fixed income, and cash.
• Go to the YourSuper comparison tool (via ATO website), search your fund and compare its long‑term net returns and fees to peers.
• Ask your fund (or a licensed adviser) to show you an option with lower domestic equity concentration but comparable or higher long‑term returns.

4. What “good” looks like:

• Your super is not overwhelmingly concentrated in Australian shares purely for franking credits and has a diversified mix aligned with your risk tolerance and retirement horizon.

3. Stress‑test your plan against franking credit rule changes

1. Action: Model your retirement income with and without refundable franking credits.
2. Tool/portal:

• Use a free ASIC Moneysmart retirement calculator (or similar official calculator) to project income under different yield assumptions, then manually adjust for franking.

3. Steps:

• Input your current balance, contributions, and an assumed cash yield (exclude franking) into the calculator to see projected income.
