Franking Credits vs Unfranked US Income: What Australian Investors in US Markets Need to Know

EOFY is six weeks away. If you’ve been collecting US dividends this financial year and haven’t started organising your records, now’s the time. But before we get to admin, let’s talk about the structural tax difference that every Australian investor in US markets needs to understand — because it affects how you build your portfolio.

What Franking Credits Actually Are

Franking credits — also called imputation credits — exist because of a simple principle: company profits shouldn’t be taxed twice.

Here’s how it works in Australia. A company like BHP earns a profit and pays 30% corporate tax to the ATO. When it distributes a dividend to shareholders, it can “frank” that dividend — attaching a credit that represents the tax already paid at the company level. When you lodge your tax return, the grossed-up dividend (the cash payment plus the franking credit) goes into your assessable income, but you get a dollar-for-dollar offset against your tax liability for the credit.

The practical result: if your marginal tax rate is lower than 30%, you can actually receive a tax refund on a fully franked dividend. If your rate is higher than 30%, you pay the difference. It’s an elegant system — one of the genuinely smart structural features of the Australian tax code — and it’s a significant reason why high-yield ASX dividend payers like the big banks and Telstra hold such appeal for retirees and low-to-middle income investors.

A fully franked $1,000 dividend is not just $1,000. It arrives with a $429 franking credit attached (30% tax on the underlying profit). The grossed-up dividend is $1,429. A shareholder on a 32.5% marginal rate (plus 2% Medicare Levy = 34.5%) pays 34.5% on $1,429, which is $493 — minus the $429 franking credit — meaning the net tax owing is just $64 on that $1,000 dividend. That’s an effective tax rate of about 6.4%.

Why US Dividends Don’t Get This Treatment

Here’s where it gets important. The franking system is built on Australian corporate tax. When a US company like Apple, Microsoft, or Nvidia pays a dividend, it has paid corporate tax — to the United States government, at the US federal rate. The Australian Tax Office has no visibility on that tax, and no mechanism to pass it through to Australian shareholders as a credit.

Result: every dollar of US dividend income you receive is unfranked in Australia. There are no credits attached. The income lands in your assessable income at full face value, and you pay tax at your marginal rate.

That said, there’s a partial offset. Under the Australia-US tax treaty, US withholding tax on dividends is capped at 15% for Australian residents. This means the US takes 15 cents in every dollar before you even see the money — but you can claim that withholding tax as a foreign income tax offset (FITO) against your Australian tax liability. You don’t lose the withholding tax entirely; it becomes a credit against what you owe the ATO. But it doesn’t zero out your Australian liability the way a full franking credit would.

Running the Numbers: Franked vs Unfranked

Let’s make this concrete. Two investors, both on a 32.5% marginal rate plus 2% Medicare Levy — effective rate of 34.5%. Each receives $1,000 in dividend income.

Investor A: Fully franked ASX dividend (e.g. CBA)

• Cash dividend received: $1,000
• Franking credit: $429
• Grossed-up assessable income: $1,429
• Tax at 34.5%: $493
• Less franking credit: -$429
• Net tax payable: $64
• Net after-tax return: $936 ($1,000 - $64)

Investor B: Unfranked US dividend (e.g. Apple)

• Gross dividend: $1,176 (before US withholding)
• US withholding tax at 15%: -$176
• Cash received: $1,000
• Assessable in Australia: $1,176 (grossed up for FITO)
• Australian tax at 34.5%: $406
• Less FITO (the $176 withheld): -$176
• Net Australian tax payable: $230
• Net after-tax return: $770 ($1,000 - $230)

The gap is real: $936 versus $770 on an identical $1,000 in headline dividend income. That’s a 21.5% difference in after-tax outcome — material if you’re building a dividend portfolio.

Note: these calculations are simplified illustrations. Your actual tax position depends on your total income, offsets, and individual circumstances. Talk to a registered tax adviser.

Does This Mean You Should Avoid US Stocks?

Not for a second.

The franking credit advantage is real — but it’s only relevant if you’re optimising for dividend income. And most of the compelling opportunities in US markets aren’t dividend plays. They’re growth stories.

Nvidia, Microsoft, Alphabet, Amazon — these companies pay minimal dividends or none at all. The returns come from capital gains, not income distributions. Capital gains in Australia are taxed at your marginal rate, with a 50% CGT discount for assets held over 12 months — meaning a 34.5% marginal rate investor effectively pays 17.25% on long-term capital gains. There’s no US equivalent of the franking credit system for capital gains either, but the asymmetry matters less because the 12-month CGT discount makes long-held US growth positions very tax-efficient in Australia.

The smarter framing is portfolio segmentation. If you’re building a high-yield income stream and you want the franking credit benefit to work for you, weight your ASX holdings toward high-yield fully-franked blue chips. Use your US allocation for growth — compounding capital gains over long hold periods, using the 50% CGT discount as your tax lever. Don’t fight the structural advantage of each market; use both.

EOFY Checklist for US Investors

30 June is six weeks away. Here’s what to get sorted:

1. Dividend records. Every US dividend you’ve received this financial year needs to be declared. Pull your transaction history from CommSec International, Stake, Superhero, or whatever platform you use. Note the gross dividend, the US withholding tax, and the AUD equivalent (based on the exchange rate at the time of receipt).

2. FITO eligibility. Confirm which withholding taxes qualify as foreign income tax offsets. Not all foreign taxes are eligible — but US withholding tax under the treaty generally is. Your accountant or tax software (e.g. myTax) will walk through this.

3. Capital gains. If you’ve sold any US positions this year, document the acquisition cost, sale proceeds, and hold period. The 12-month CGT discount is significant — it matters whether you held for 11 months or 13.

4. Currency conversion. All foreign income must be converted to AUD at the exchange rate at the time of the transaction. ATO guidance on exchange rates is available on the ATO website; keep records of the rates you’ve used.

5. Tax adviser. If your US holdings are material, get a proper review. The interaction between FITOs, CGT, and the Medicare Levy Surcharge can get complex fast, and an hour with a tax adviser is cheap relative to the errors you can make going it alone.

The Bottom Line

Franking credits are a genuine advantage of the Australian tax system — and they matter if you’re building for income. But they’re not a reason to underweight US equities. The growth differential between US and ASX markets over the past decade has dwarfed any franking credit advantage on the income side. US markets offer depth, diversification, and access to industries that simply don’t exist on the ASX at scale.

Tax the income correctly, hold growth positions for 12+ months, and build a portfolio that uses each market for what it does best. That’s the play.
