Every atomic assertion extracted from the underlying record, ranked by evidence strength.
Treasury states the reforms "will help level the playing field for first home buyers, preserve the gains investors have made, and support investment in new housing supply."
Combined with recent and expected interest rate increases, the changes are expected to see a 34% fall in new investor activity near-term.
Total housing market turnover is expected to decline 20%.
Tax changes announced in the Federal budget on May 12 are expected to significantly affect Australia's housing markets.
Dwelling price growth is now expected to stall flat on average across the major capital cities for calendar 2026.
Over the medium to longer term, the changes are expected to see more muted price cycles.
This risk is due to slowdown in turnover, uncertainty about tax changes, and higher interest rates.
The risk is mitigated somewhat by grandfathering provisions and positive price expectations.
Over the medium to longer term, the changes are expected to see a small, gradual lift in rental yields.
Over the medium to longer term, the changes are expected to see a modest lift in new dwelling construction.
Over the medium to longer term, the changes are expected to see a gradual shift towards 'landlordism'.
From July 2027, the capital gains tax discount applied to future capital gains on investments will move from a flat 50% to cumulative inflation over the holding period.
The taxable component of capital gains will continue to be taxed at marginal rates but with a new minimum rate of 30% being applied.
From budget night, net losses on new residential property investments will not be able to be deducted from other (non-property) income, such as wages.
Net losses on new residential property investments will still be able to be deducted from rental income, including from other rental properties.
Any resulting losses from new residential property investments can be carried forward to future tax years.
From July 2028, there will also be a new 30% minimum tax rate applied to discretionary trusts and similar vehicles.
Negative gearing will continue to be available for investments made prior to budget night (grandfathering).
Capital gains on existing investments up to July 2027 will also continue to receive a 50% discount (grandfathering).
New investments in newly built dwellings will still be able to be negatively geared.
New investments in newly built dwellings will have an option for capital gains to be discounted by either 50% or cumulative inflation.
The changes unwind the 50% CGT discount that was introduced in 1999 for new investment in existing dwellings.
The changes to negative gearing remove a treatment that was introduced in 1936 (with limits briefly in place in 1985-87).
The overarching goal of the reforms is to shift the balance from house purchase as a pathway to wealth-creation back towards home ownership.
House price growth has been more than double the growth in average full-time earnings since 1999.
Home ownership amongst 25-34 year olds has declined from 50% to 43% over the last 20 years.
The primary effect of the reforms is to reduce the relative attractiveness of new leveraged investment.
Inflation indexation for CGT means it is still discounted, and in some cases, can be more favorable than the previous 50% discount for moderate or steady capital gains.
Large 'jackpot' capital gains are treated very differently, with the 50% discount being a much bigger concession than inflation adjustment.
The removal of negative gearing is the more material change for most investors.
Treasury estimates about a third of negatively geared rental properties receive an outright tax subsidy over the life of the asset.
Grandfathering strongly encourages current holders of leveraged investments that are negatively geared to retain these assets for as long as possible.
Current holders are likely to retain assets and seek to maximize tax benefits, e.g., by carrying higher levels of debt.
New investors in newly built dwellings will also be eligible for the negative gearing tax treatment.
The carve-out for new investment in newly built dwellings will be significantly more attractive compared to investment in existing dwellings.
Currently, 18% of new investor finance approvals are for the construction or purchase of newly built dwellings.
About half of property investors are negatively geared, implying this is an important consideration for about half of all investor purchases (around 110k a year).
Sharply lower investor activity will skew more heavily towards new dwellings, with the share potentially rising towards 40-50% of new investor loans.
The new minimum tax rate on CGT reduces the tax advantage of realizing capital gains when income is low.
The average marginal tax rate on capital gains over the last 13 years was 25%, 7 percentage points lower than the individual's average marginal tax rates over the 15 years prior.
The tax-free threshold is $18.2k, with the lowest 16% rate applying up to $45k.
The introduction of a 30% minimum rate raises the rate on up to $45k of any taxable capital gain an individual records, equating to $9.2k.
The minimum rate is still below the 37% and 45% marginal rates, so sellers can still reduce tax by realizing gains in low income years, but the benefit is smaller.
The RBA's three 25bp interest rate increases in February, March, and May have taken official interest rates back to restrictive levels of 2023-24.
These RBA moves already appear to be weighing on activity and prices in some markets.
Most of Australia's housing markets continue to see tight supply, with conditions extremely tight in several capital cities.
Rental vacancy rates have been holding around historical lows since mid-2023 and are below 1% in Brisbane, Adelaide, and Perth.
On-market supply has been low, with total listings across major capital cities dropping to a 20-year low of two months of sales late last year.
Brisbane, Adelaide, and Perth stand out as having particularly tight on-market supply.
Underlying physical demand for housing, driven by population growth and household formation rates, has been relatively solid and is expected to sustain its recent pace.
Population growth has been robust, holding at 1.5% per year.
Robust population growth was a key factor in the market's resilience through the 2022-24 interest rate tightening cycle.
The 2022-24 cycle saw an initial price correction in 2022 followed by a surprisingly strong rebound in 2023 and 2024.
The mix of new investor activity is expected to skew more towards newly built dwellings.
Growth in the total value of outstanding investor credit is expected to slow from around 9.5% per year to below 7% per year by end of this year.
Growth in the total value of outstanding investor credit is expected to slow to around 4.0% per year by the end of 2027.
There will be mixed impacts on investor loan repayments, with an incentive for existing investors to refrain from selling but also to hold more debt.
The share of newly built dwellings in investor activity is expected to rise from 20% to around 40%.
The share of newly built dwellings is expected to rise in absolute terms despite the fall in total investor activity.
The decline in dwelling turnover is led by the slowdown in investor demand and few investor properties being sold.
