## What Small Businesses Need to Know for Compliance
Whether operating as sole traders, partnerships or small companies, here are steps to stay compliant and maximise benefit:
### Review payroll withholding
- Employees previously taxed at 16% on lower income bands may see reduced withholding rates from 1 July 2026. Update payroll systems to ensure withholding aligns with new bracket structures.
- Communicate changes to staff so they understand potential increases in take-home pay.
### Update personal tax planning strategies
- For sole traders, reconsider **income structuring** between individual and business if profit distributions push into higher brackets.
- Superannuation contributions, investment income, and deductions might shift marginal tax effects. Break up income across tax years if possible to benefit from lower rate in new year.
### Adjust estimated tax repayments and instalments
- If you pay **PAYG instalments**, your baseline could be affected by the cut; review estimates to avoid overpayment or underpayment penalties.
- Trusts or entities distributing profits around the tax year-end may need to time distributions to maximise impact.
### Ensure systems & accounting software are ready
- Many accounting and payroll systems need updates to tax tables ahead of the rate changes. Test systems before 1 July to avoid errors.
- If using external bookkeepers or payroll services, ensure they’re aware and plan in advance.

## Example Scenario
Laura runs a small consulting business as a sole trader. Her taxable income in 2025-26 is $42,000. Under the old bracket, part of her income above ~$30k may be taxed at 16%. But from 1 July 2026, all income above the tax-free threshold up to $45,000 will be taxed at the new 15%.
She can:
- defer discretionary income into the 2026-27 year, aiming to stay within the lower bracket;
- increase contributions to deductible super in 2025-26 to reduce taxable income now;
- check whether she will benefit from reduced PAYG instalments next tax installment period.
