Budget 2026 packaged six business tax measures under the headline figure of over $3.5 billion in new business tax relief. Three measures land in 2026-27, one in 2027-28, and two more in 2028-29. Together they make the small-business depreciation rules permanent for the first time since 2015, restore the COVID-era loss carry-back as a permanent feature for companies up to $1 billion turnover, and add a new loss refundability mechanism for start-ups.
1. Permanent $20,000 instant asset write-off — from 1 July 2026
Small businesses with aggregated turnover up to $10 million can immediately deduct eligible depreciating assets costing less than $20,000, on a permanent basis from 1 July 2026. Assets costing $20,000 or more continue to be placed into the small business simplified depreciation pool. The provisions that prevent small businesses re-entering the simplified depreciation regime for 5 years after opting out remain suspended until 30 June 2027.
Treasury estimates the permanent extension saves small businesses around $32 million per year in compliance costs by removing the annual “will it be extended?” question that has shaped every Budget speech since 2015.
Worked example — Coffee Co generates a $3,750 refund
From the Treasury fact sheet:
- Daniel and Eloise run Coffee Co Pty Ltd. The café made $40,000 in taxable profits and paid $10,000 in tax in 2025-26 (at the 25% small business rate).
- In 2026-27 they buy a $19,000 coffee machine, $19,000 in tables and chairs, and $17,000 in outdoor heaters. Each item is under $20,000 → fully deductible under IAWO.
- Without these purchases: $40,000 taxable profit, $10,000 tax. With them: $55,000 in deductions → $15,000 tax loss for 2026-27.
- Under the new permanent 2-year loss carry-back (next section), Coffee Co claims a refund of $15,000 × 25% = $3,750 against the prior year’s tax paid.
Net effect: a single year of asset investment converts directly into immediate cash flow.
Costing: -$815 million in receipts over 5 years from 2025-26 (this includes IAWO + the PAYG dynamic instalment changes bundled into the same measure).
2. Permanent 2-year loss carry-back — from 1 July 2026
For tax years commencing on or after 1 July 2026, companies with aggregated annual global turnover under $1 billion can carry back a tax loss and offset it against tax paid up to two years earlier. Key details:
- Revenue losses only (not capital losses).
- Limited by the company’s franking account balance — you can only generate a refund up to the tax actually paid in the prior period that is still represented in the franking account.
- Around 85,000 companies benefit, the majority small businesses.
- Treasury describes this as “reintroducing” loss carry-back — a permanent version of the COVID-era measure (which expired in 2022).
Why this matters for risk-taking
Without loss carry-back, a company that pays tax in profitable years and then makes a loss can only carry that loss forward against future income. Loss carry-back converts the loss into an immediate cash refund, smoothing the cycle and making investment less penal for businesses that have a single bad year.
Costing: -$2.3 billion in receipts over 5 years from 2025-26.
3. Start-up loss refundability — from 1 July 2028
A separate, narrower mechanism for new companies. For tax years commencing 1 July 2028, companies with aggregated turnover under $10 million that generate a tax loss in their first two years of operation can use that loss to generate a refundable tax offset.
The refundable offset is capped at the value of:
- Fringe benefits tax paid in respect of Australian employees in the loss year, plus
- Withholding tax paid on wages to Australian employees in the loss year.
In effect: the government refunds you against the employment tax remittances you’ve already made, even if you have no income tax liability to refund against. This is targeted at start-ups that hire staff before they hit profitability.
Costing: payments +$410 million over 5 years from 2025-26 (in addition to receipts impact).
4. R&D Tax Incentive reform — from 1 July 2028
Three structural shifts:
| Element | Before | From 1 July 2028 |
|---|---|---|
| Core R&D offset rate | Base + intensity-based premium | +4.5 percentage points (≈25–50% uplift in core R&D offset) |
| Intensity threshold | 2% | 1.5% |
| Supporting R&D expenditure | Eligible | Not eligible |
| Refundable offset turnover threshold | $20 million | $50 million |
| Refundability eligibility | All companies under threshold | Companies under 10 years old |
| Max R&DTI expenditure threshold | $150 million | $200 million |
| Min expenditure threshold | $20,000 | $50,000 (below: must use Research Service Provider or CRC) |
Treasury estimates the reform delivers 20% more business R&D for each dollar of tax offset and an additional $400 million per year of R&D investment by young firms.
Costing: -$910 million in receipts and -$1.6 billion in payments over 5 years (i.e. the new core uplift is partly self-funded by tightening eligibility).
5. Venture capital expansion — from 1 July 2027
The investee-size caps that limit which businesses can receive concessionally-taxed VC investment are lifted:
| Cap | Before | From 1 July 2027 |
|---|---|---|
| VCLP investee asset cap | $250 million | $480 million |
| ESVCLP investee asset cap | $50 million | $80 million |
| ESVCLP tax-exempt investee cap | $250 million | $420 million |
| Max ESVCLP fund size | $200 million | $270 million |
The existing Eligible Venture Capital Investor (EVCI) program is closed to new applications from 7:30 PM AEST 12 May 2026 — existing participants are unaffected, but the program no longer accepts new entrants.
6. $250 Working Australians Tax Offset — from 2027-28
The $250 WATO is a separate Budget measure (covered in its own insight) but is relevant here because sole traders running their own business are explicitly eligible for the offset against their business income. The offset is applied to “income derived from work” — wages, salaries, and the business income of sole traders.
Together with the legislated 15% → 14% drop in the second marginal bracket from 1 July 2027 (Treasury’s “five tax cuts” framing), this lifts the effective tax-free threshold for working sole traders to $19,985, or up to $24,985 for low-income earners eligible for LITO. WATO + the 14% rate both commence in 2027-28.
Wider operating-environment changes
Outside the tax measures themselves, several adjacent reforms compound the cash-flow benefit:
- Permanent extension of dynamic PAYG instalments and monthly opt-in from 1 July 2027. ATO will not charge interest where businesses get an instalment variation wrong using an ATO-approved calculator.
- 497 nuisance tariffs abolished from 1 July 2026 (bringing the two-year total to ~1,000 abolished tariffs) — saving businesses $157 million per year in compliance costs and streamlining ~$23 billion of trade.
- ACCC penalties doubled from $50M to $100M for anti-competitive conduct.
- Free mandatory Australian Standards across construction, OHS and product safety — saves some small firms up to $1,600/year.
- Mental health and financial wellbeing — additional $8 million from 1 July 2026 for NewAccess for Small Business Owners and the Small Business Debt Helpline.
