Tax, Real Incomes
& The Fiscal Squeeze
& The Fiscal Squeeze
How inflation, tax, and interest rates are quietly reshaping what your income can actually do — across every level of Australian earnings
Every lifestyle has a price tag — and that price tag rises every year, whether or not your income does.
Today's household budget may balance. Today's mortgage, today's school fees, today's weekend habits may all sit comfortably within today's income. But the question a financial planner is always really asking is a different one: will the same life still be affordable in two years? In five? In ten?
That question is shaped — often invisibly — by three forces working constantly on your financial position. They don't announce themselves. They don't send letters. They simply compound, year after year, until one day the maths no longer works the way it used to.
While every household navigated its own financial pressures, Australia itself was managing its own version of the same story — population growth, rising service demands, debt accumulation, and the constant tension between what we want from government and what we're prepared to pay for it.
The forces pressing on individual finances — inflation, tax, interest rates — are not random. They are, to a significant degree, the product of policy decisions made at the national level. And those decisions are themselves driven by a population that is growing, ageing, and making increasing demands on public services.
Between 2010–11 and 2025–26, 5.7 million people joined Australia. Some were born here. Some moved here. It doesn't matter much which, because the impact is the same either way: 5.7 million people who needed somewhere to live. Somewhere to work and earn an income. Somewhere to shop, somewhere to go to school, somewhere to be treated when they were sick. 5.7 million people who needed roads to drive on, water to drink, courts to resolve their disputes, and a government willing to be responsible for their safety and their basic welfare.
Some of those 5.7 million became taxpayers and productive contributors almost immediately. Some — the very young, the very old, those arriving with little — drew on services long before they could contribute to funding them. Most, over time, would become net contributors. But in the meantime, Australia's governments had to find ways to stretch every existing hospital, school, road, and welfare programme further — or build new ones. That costs money. And when governments spend more money than they collect, the difference becomes debt. Debt that has its own carrying cost, paid for by future taxes on future Australians.
This is not a criticism of immigration or of population growth. A larger population also means a larger economy, more workers, more taxpayers, more dynamism. It is simply an honest account of how scale works: more people means more demand on everything, and someone has to work out how to pay for it.

Per-capita government spending nearly doubling in 16 years is not necessarily a failure — it reflects real service demands from a growing and ageing population. But it does mean that the tax burden required to service that spending is real, and growing. The fiscal environment is not background noise to financial planning decisions. It is the stage on which those decisions play out. Government debt of $41,400 per person is, ultimately, a deferred tax claim on future income — potentially including yours.
We take a financial planner's lens to sixteen years of Australian data — 2010–11 through 2025–26 — across five income levels, from $60,000 to $250,000. We track what tax actually took from each income every year. We measure what inflation did to purchasing power. We expose the gap between what the numbers look like and what they actually mean for the capacity to keep living the way you currently live.
In the process, we surface some of the less obvious dimensions of financial planning — the kind of things that only become visible when you lay the data out year by year, side by side, and look at it honestly.

What 16 years of data shows — for individual households and for Australia as a whole
Wages grew 69% on average. Costs grew 53%. On that arithmetic, the average worker whose income tracked the average came out modestly ahead in real terms — still living the same life, but with a little more room. That is the good outcome. The problem is that "the average" is the summary of a very wide distribution, and what matters is where you sit within it. The distance between being on the right side and the wrong side of that average, compounded over sixteen years, is not a rounding error. It is the difference between financial comfort and financial stress.
All five income levels in this analysis — $60,000, $90,000, $120,000, $180,000 and $250,000 — are held constant across the full 16 years. The gross income doesn't change. This is deliberate: it isolates the effect of tax policy and inflation from the separate question of whether someone got a pay rise. Many Australians are in exactly this position — self-employed people whose business income has plateaued, retirees drawing a fixed pension amount, investors living off income that hasn't grown with the market. For them, the squeeze is not hypothetical. It is the numbers in the table above, applied to their actual life.

| Financial Year | $60,000 Net | $90,000 Net | $120,000 Net | $180,000 Net | $250,000 Net |
|---|
Highlighted year: 2011–12 shows lower net income due to one-off Flood Levy. LMITO years (2018–19 to 2021–22) show temporarily improved figures. Largest structural improvement: 2024–25 (Stage 3).
Effective tax rates are lower across the board in 2025–26 than in 2010–11. Stage 3 (modified) delivered the most significant single-year reduction. The structural direction has been downward. The problem is that CPI has run much faster than these tax gains.
CPI-indexed living costs vs static after-tax income — $90,000 earner
Base living costs are set at 90% of the 2010–11 net income ($60,660), then indexed forward by the annual CPI each year. The "buffer" shows whether a static $90,000 earner can maintain that 2010–11 standard of living.
Inflation — especially the 6.1% in 2021–22 and 5.4% in 2022–23 — has permanently widened the gap. Stage 3 tax reform helps, but by 2025–26 the static $90,000 earner is approximately $20,000 per year short of maintaining their 2010–11 standard of living. That is Falinski's "$2,700 per year" observation, compounded.

How AWOTE has grown — and what that means if your income hasn't
Average Weekly Ordinary Time Earnings (AWOTE) grew 69% from 2010–11 to 2025–26 — from $63,180 to $106,652 annually. A $90,000 earner whose income grew at the same rate would now earn $151,856 gross. Those whose income has not kept pace have experienced a real decline in their relative position in the income distribution.

The "static income" analysis is not academic — it describes real groups of people whose gross income is constrained or fixed:
Self-employed individuals whose business income has plateaued or declined in real terms. Unlike employees, they do not receive mandated Enterprise Agreement increases or automatic CPI adjustments.
Retirees drawing account-based pensions at a fixed dollar amount (rather than a percentage of a growing balance). Their income is directly the static amount they draw.
Those on fixed-rate salaries in industries where real wage growth has been below AWOTE — sectors including parts of retail, hospitality, and small business administration.
Investors living off investment income that has not grown with inflation — dividend yields that haven't kept pace, or rental income in markets where rents haven't fully indexed.
The analysis does not claim all Australians are on static incomes. It demonstrates what the intersection of tax policy, inflation, and income stagnation means for those who are.
Commonwealth spending, deficits, and debt — 2010–11 to 2025–26
The individual tax squeeze does not exist in isolation. It is the demand side of a fiscal equation whose supply side — government expenditure — has expanded substantially and, critically, structurally. Two surplus years in sixteen do not indicate fiscal repair; they indicate a windfall commodity cycle.

Falinski argues (AFR, 17 March 2026) that tax reform proposals that do not address expenditure growth are treating symptoms. The data supports this: even with Stage 2 and Stage 3 reforms reducing effective rates, the structural claim the Commonwealth makes on GDP has grown from 24% to 27.8%. The individual tax squeeze and the government fiscal expansion are two sides of the same coin. Tax reform without expenditure discipline merely redistributes the burden — it does not reduce it.
Australia recorded surpluses in 2022–23 (+$22.1B) and 2023–24 (+$15.8B). These are genuine accounting surpluses and should not be dismissed. But context matters:
Commodity-driven receipts: The surpluses were driven by elevated iron ore, coal, and LNG prices boosting company tax revenues — not by structural expenditure restraint. Commodity prices are now moderating.
Gross debt continued to rise: Even during the surplus years, gross Commonwealth debt grew — from $953B (2021–22) to $982B (2022–23) to $1,038B (2023–24). This is because the underlying cash balance excludes some capital transactions that still require borrowing.
Structural spending base: Once commodity revenues normalise, the structural spending level (~26–28% of GDP) produces deficits without corresponding receipts. The 2024–25 and 2025–26 estimates return to deficit for precisely this reason.
The NDIS trajectory: NDIS spending continues to grow faster than nominal GDP, representing a structural spending obligation that is not captured in the two-year surplus narrative.
