Running a small business in Australia

7 factors that shape how a small business operates here — tax and e-invoicing, payments, labour and licensing — each with its source and the date it was checked.

1. E-invoicing & Tax Compliance

   Peppol e-invoicing: B2G default, B2B voluntary; agencies pay e-invoices in 5 days

   Detail: Commonwealth agencies must receive Peppol e-invoices, pay them within 5 days under the Pay On-Time or Pay Interest policy, and target 30% of invoices via e-invoicing by 1 July 2026 with automated sending by December 2026. B2B e-invoicing remains voluntary (the proposed Business E-Invoicing Right was not enforced); PINT A-NZ has been the only supported format since 15 May 2025.

   Why it makes work harder: SMBs that can send Peppol invoices get paid by government in days rather than weeks; those without it are stuck with slower channels, making Peppol capability a cash-flow lever.

2. E-invoicing & Tax Compliance

   10% GST

   Detail: Australia's federal GST is 10% (PwC, reviewed 1 September 2026), reported through periodic Business Activity Statements; the ATO does not receive each invoice in real time.

   Why it makes work harder: SMBs must still reconcile GST on quotes, invoices and expenses for each BAS, a recurring admin burden for sole traders.

3. Labour & Licensing

   Payday Super: super due within 7 business days of each payday from 1 July 2026

   Detail: From 1 July 2026 employers must pay superannuation at the same time as wages, with contributions reaching funds within 7 business days (20 business days for a new employee's first contribution), replacing quarterly payment. The ATO's Small Business Superannuation Clearing House closed from 1 July 2026, and the ATO now assesses the SG charge with daily-compounding interest plus an administrative uplift.

   Why it makes work harder: Small employers lose the quarterly float on super and must process super every pay run, squeezing cash flow and forcing a move off the free ATO clearing house to payroll/software solutions.

4. Labour & Licensing

   Late super also a Fair Work breach

   Detail: The Fair Work Ombudsman notes that from 1 July 2026 super must be paid with wages and received within 7 business days, and that late payment may also breach the Fair Work Act or an applicable award or enterprise agreement, in addition to ATO charges.

   Why it makes work harder: Payroll errors now carry dual regulatory exposure (ATO and FWO), raising stakes for SMBs running payroll in spreadsheets.

5. Late Payment & Credit

   Payment disputes and digital-platform disputes dominate small business complaints

   Detail: The Small Business Ombudsman (ASBFEO) received 8,623 assistance requests in 2025-26; digital platform disputes (925 cases, nearly tripling) and payment disputes (707 cases) made up about 70% of managed disputes. 97% of actively trading businesses employ fewer than 20 people.

   Why it makes work harder: Late/unpaid invoices and dependence on platforms (marketplaces, ad platforms, app stores) are the leading pain points, supporting owned channels and automated collections.

6. Late Payment & Credit

   Payment Times Reporting Scheme exposes big-business payment to small suppliers

   Detail: Under the Payment Times Reporting Scheme, large businesses and some government enterprises must report every six months on how quickly they pay small business suppliers; ASBFEO recommends e-invoicing and systematic follow-up before and after due dates.

   Why it makes work harder: Transparency exists but no hard legal maximum term applies to private B2B, so small suppliers still carry the collection effort.

7. Market Size

   2.8 million actively trading businesses

   Detail: The ABS counted 2,814,778 actively trading businesses at 30 June 2026 (released 18 August 2026), including 689,600 with 1-4 employees and 232,912 with 5-19 employees; non-employing businesses grew 4.8%.

   Why it makes work harder: A large, growing base of sole traders and micro-employers without back-office staff is exposed to Payday Super and invoicing admin.
