Key Tax Changes Affecting Melbourne Small Businesses This Year

If you run a small business anywhere from the CBD laneways to Brunswick, Richmond or the Bayside strip, this year brings more compliance change than most. Superannuation has jumped, ATO interest has stopped being deductible, and a new payday reform is coming for payroll teams. None of it is optional, and the ATO's data-matching means mistakes get found fast. Here's what actually matters for Melbourne small businesses right now.

Superannuation Guarantee Now Locked at 12%

From 1 July 2025, the superannuation guarantee (SG) rate hit its final legislated step of 12% under the Superannuation Guarantee (Administration) Act 1992. This was the last scheduled increase in the multi-year phase-in, so unlike previous years there's no further automatic rise pencilled in.

• Every payroll run since 1 July 2025 needs SG calculated at 12% of ordinary time earnings.
• Award rates and employment contracts that reference "SG rate" rather than a fixed percentage should already be updating automatically in Xero — but it's worth checking manually if you run a custom pay template.
• Melbourne hospitality and retail employers with casual staff on penalty rates are the most common place we find under-calculated super, because loadings get missed in the OTE base.

If you haven't reconciled your super obligations since the rate change, run a payroll audit before your next quarterly lodgement.

Payday Super Reform Starts 1 July 2026

The federal government has confirmed Payday Super is proceeding, with a start date of 1 July 2026. Instead of paying super quarterly, employers will need to pay SG contributions to an employee's fund within days of paying their wages.

• This is a major cash flow shift for Melbourne small businesses used to quarterly super timing — you'll need to fund super every pay cycle, not once a quarter.
• Xero's payroll module is being updated to support near-real-time super batching; if you're still on manual spreadsheets or an older payroll system, now is the time to move.
• Late payments under the new regime will trigger the superannuation guarantee charge (SGC) faster and more often than under the current quarterly system.

We're already helping clients model their 2026-27 cash flow around weekly or fortnightly super payments instead of one big quarterly hit.

ATO Interest Charges Are No Longer Deductible

From 1 July 2025, the general interest charge (GIC) and shortfall interest charge (SIC) charged by the ATO are no longer tax deductible under the Income Tax Assessment Act 1997. Previously, businesses running a tax debt could at least offset some of the pain through a deduction — that's gone.

• Any overdue BAS, PAYG withholding, or income tax debt now costs more in real terms than it did last financial year.
• Melbourne businesses sitting on ATO payment plans should review the total cost of that debt versus refinancing through a business line of credit.
• This change makes on-time BAS lodgement and payment more financially important than ever — even a short delay is now a pure after-tax cost.

The $20,000 Instant Asset Write-Off

The $20,000 instant asset write-off continues to be extended for small businesses with aggregated turnover under $10 million, allowing an immediate deduction for eligible depreciating assets first used or installed ready for use within the relevant income year.

• Because this threshold requires fresh legislation each year rather than being permanent, always confirm current-year eligibility before committing to a big equipment purchase.
• Popular with Melbourne trades, allied health clinics and hospitality venues upgrading kitchen or fit-out equipment — but the asset must be installed and ready for use, not just ordered, by the cut-off.
• Assets over the threshold still get added to the small business simplified depreciation pool and written off over time.

Fair Work Minimum Wage Increase

The Fair Work Commission's annual wage review flows through from the first full pay period on or after 1 July each year, lifting minimum award rates and the national minimum wage. For Melbourne employers in retail, hospitality, cleaning and allied health, this affects:

• Base award rates across most modern awards administered under the Fair Work Act 2009.
• Superannuation obligations, since SG is calculated on the new higher ordinary time earnings.
• Payroll tax thresholds in Victoria if the wage increase pushes your total Victorian wages bill over the payroll tax-free threshold.

Update your Xero pay templates and award interpretation rules as soon as the new rates are confirmed — don't wait until an underpayment shows up in a Fair Work audit.

Div 7A and Trust Distribution Traps

Division 7A of the Income Tax Assessment Act 1936 continues to catch out Melbourne trading trusts and family companies that draw funds informally from the business. The ATO's ongoing focus on unpaid present entitlements and loans from private companies to shareholders or associates means:

• Any informal drawings need a compliant Div 7A loan agreement with minimum yearly repayments at the ATO benchmark interest rate.
• Trust distributions to related companies that remain unpaid can be deemed a Div 7A loan if not properly documented.
• This is one of the most common issues we see when reviewing new Melbourne clients' prior-year returns — it's cheap to fix early and expensive to fix after an ATO review letter arrives.

What Melbourne Businesses Should Do Now

None of these changes are dramatic on their own, but together they shift the cost of getting compliance wrong. Super at 12%, non-deductible ATO interest, and the incoming Payday Super reform all point the same direction: pay on time, every time, because the margin for error has shrunk.

• Reconcile payroll now to confirm SG is calculating correctly at 12%.
• Model cash flow for more frequent super payments ahead of the 2026 Payday Super start.
• Clear ATO debt where possible — the interest is no longer softened by a deduction.
• Review Div 7A loans and trust distributions before your accountant finalises this year's return.
