A significant proposed tax policy from the Coalition, aiming to permanently address "bracket creep" by indexing income tax brackets to inflation, is drawing sharp critiques regarding its potential cost and distributional effects. While the plan, championed by figures like Angus Taylor, promises automatic annual tax cuts equivalent to the inflation rate, initial assessments suggest the budgetary impact might be higher than initially presented, particularly in the early years of implementation.
The core of the Coalition's pitch involves a structural shift in how tax thresholds are adjusted, moving from discretionary changes to automatic indexing against inflation. This mechanism is intended to prevent wage growth, driven by inflation, from pushing individuals into higher tax brackets without a real increase in their purchasing power. However, analyses indicate that this seemingly straightforward adjustment could lead to a larger budget deficit compared to alternative proposals, at least within the first two years of government.

Deeper Dive into Costings and Beneficiaries
Further complicating the picture are specific proposals, such as the first home buyer mortgage deduction scheme. Economists caution that the assumed demand stimulation from this policy may be underestimated, potentially ballooning its cost to the federal budget significantly beyond the projected $1.25 billion. This plan, touted by Opposition Leader Peter Dutton, offers prospective first-time buyers deductions on newly built home mortgage interest for five years, aiming to provide substantial annual savings.
The distribution of benefits from the Coalition's broader tax plan also appears to skew towards higher-income earners, a point noted by tax experts. While many taxpayers may see an improvement compared to the status quo, those on higher incomes stand to gain the most. This contrasts with some expectations that broad-based tax reform should aim to alleviate burdens across the income spectrum more evenly.

Bracket Creep and its Implications
The concept of 'bracket creep' itself refers to the unintended consequence of a progressive tax system where inflation or cost-of-living adjustments in wages can push individuals into higher tax brackets, increasing their tax burden even if their real income hasn't grown. The Coalition's proposed solution aims for a permanent fix by directly linking tax thresholds to inflation, effectively replacing the existing practice with an ongoing annual tax reduction.
Historical Context and Expert Reservations
Concerns about the affordability and fairness of large-scale tax plans are not new. Past assessments, such as those from the Grattan Institute in April 2019 concerning a previous $300 billion tax plan, have highlighted potential issues of affordability and the unequal distribution of benefits, particularly favouring high-income earners. The present proposal appears to tread similar ground, with current analyses from sources like The Conversation and independent reports pointing to a less favourable short-term deficit outcome compared to other major parties. The effectiveness of such a plan in truly addressing underlying economic barriers, particularly for second-earners entering the workforce, remains a subject of debate, with historical tax reviews suggesting more comprehensive reform might be needed to address these specific economic incentives.
