Franking credits, explained with one $70 dividend

Franking credits are one of those Australian institutions — like preferential voting or the flat white — that locals treat as obvious and everyone else finds mildly exotic. Very few countries run a full dividend imputation system. Ours changes the real return of almost every income stock on the ASX, so it's worth getting the mechanics straight.

The arithmetic

A company earns $100 of Australian profit and pays company tax at 30% — $30 to the tax office, $70 left. It pays that $70 to you as a fully franked dividend. Attached to it is a franking credit for the $30 of tax already paid.

At tax time you declare the grossed-up amount — the full $100 — as income, and the $30 credit counts as tax you've already paid. If your marginal rate is above 30%, you top up the difference. If it's below 30%, the excess is refunded in cash. That last part matters enormously: superannuation funds in accumulation are taxed at 15%, and pension-phase accounts at zero, so for much of Australia's retirement savings pool a franking credit isn't a discount — it's a cheque.

Why the system exists

Imputation was designed to end double taxation. Without it, the same profit gets taxed once inside the company and again in the shareholder's hands. With it, company tax becomes effectively a prepayment of the shareholder's own tax. Reasonable people argue about the policy; the mechanics are what they are.

How it shapes the market

The fingerprints are everywhere. Australian companies pay out an unusually high share of profits as dividends, because a franked dollar in shareholders' hands is worth more than an unfranked one retained. Research notes quote "grossed-up yields" — the headline yield inflated to include the credit — because that's the number a low-tax investor actually receives. And companies earning mostly offshore profits can't fully frank, since credits are only generated by Australian tax paid; their dividends are structurally less valuable to local investors, which subtly tilts the whole market's preferences toward domestic earners.

One caveat worth knowing exists: holding-period rules mean you generally can't harvest credits by darting in and out of a stock around its dividend date. The system rewards owners, not tourists.

The practical takeaway is simple: for an Australian taxpayer, comparing a fully franked yield to an unfranked one without adjusting is comparing an apple to about two-thirds of an apple. Franking is not a bonus on top of total return. For local investors, it is part of total return.
