Super, tax & contributions

Super vs outside-super savings (and how each is taxed)

Super in pension phase is tax-free; savings outside super are taxed on their earnings. That difference drives where you hold money and which you spend first.

Contribution caps & salary sacrifice

You can add to super pre-tax (concessional) or after-tax (non-concessional), each capped per year. Salary sacrifice is the main lever to build super faster.

Recontribution: turning taxable super into tax-free

Withdraw a lump sum from super after 60 and put it straight back as an after-tax contribution. It doesn't change how much you have — it converts the 'taxable' part of your super into the 'tax-free' part, which mainly cuts the tax your beneficiaries pay when you die.

The Transfer Balance Cap (tax-free super limit)

There's a lifetime limit on how much super you can move into a tax-free pension. Above it, the excess stays in accumulation and its earnings are taxed at 15%.

Super fees and why they matter

A percentage fee quietly reduces your return every year and compounds over decades. The planner models fees explicitly because they're often the biggest gap in a forecast.

LITO & SAPTO: the offsets that keep retirees' tax low

Two tax offsets — the Low Income Tax Offset (for everyone) and the Seniors and Pensioners Tax Offset (from Age Pension age) — cut the tax you owe. Together with the tax-free threshold and tax-free super, they're why most retirees pay little or no income tax.

Transition to Retirement: same take-home, more super, less tax

From age 60 you can salary-sacrifice more and draw a tax-free TTR pension to replace the pay you give up — shifting income from your marginal rate down to super's 15%. Your take-home holds; the tax you save builds super.

Other income streams (DB pensions, annuities, foreign pensions)

Lifelong income outside super — a defined-benefit pension, annuity, or foreign pension like US Social Security — modelled as a first-class source that offsets your drawdown.

Non-resident (foreign resident) tax

If you retire permanently overseas, Australian tax works differently — no tax-free threshold, only Australian-sourced income is taxed, and the Age Pension generally can't be claimed from abroad.
