Registration, then RevenueSA. BAS agent registration with the Tax Practitioners Board is national, and our main bookkeeper page covers how a site should display it and where bookkeeping stops and BAS services start; our page for Adelaide accountants deals with land tax and stamp duty. The state work an employer is more likely to hand a bookkeeper is payroll. RevenueSA's registration point is $1.5 million a year in Australia-wide taxable wages. Registered employers then lodge a return every month, due on the 7th of the month after, followed by an annual reconciliation, which for 2025-26 was due on 28 July 2026. RevenueSA says a missed reconciliation can bring a default assessment, interest and penalty tax.
ReturnToWorkSA. Work injury insurance is the other state account most employers hold. Registration is due within 14 days of taking on a worker, unless total wages for 2026-27 will stay under $16,806; even then, an injury means reporting it, registering and paying the minimum premium. The employer remuneration return opens on 2 July each year and is due by 15 September. Employers choose between declaring last year's actual remuneration only, or actual remuneration plus an estimate for the current year, which is squared up at year end and can produce a refund or an extra bill. Premiums of more than a thousand dollars are paid in one sum by 7 October or in nine equal instalments from October to June, while smaller ones are paid in one sum by 7 November. ReturnToWorkSA held its average premium rate at 1.85% for 2026-27, the fourth year at that level, though what each business pays depends on its industry, its wages and its claims.
Two portable long service schemes. SA Portable Long Service Leave runs two schemes from Fullarton Road in Eastwood: construction and community services. Construction employers register within a month of employing covered workers and lodge a return every two months, due on the 21st of the following month (September and October 2026 are due by 21 November), with a levy of 2.00% of declared remuneration. A service day means five hours or more, casuals count once they work three such days in a month, and apprentices are recorded but levy-free. The community services scheme started on 1 October 2025. It covers employees in SCHADS Award or Aboriginal Legal Rights Movement Award classifications who provide community services, plus staff who spend at least half their time supporting that work. Its returns are quarterly, due on 21 January, April, July and October, with a levy of 2.2% of gross remuneration. The scheme links that rate to South Australia's long service entitlement of 13 weeks after 10 years, an amount many other jurisdictions only reach after 15.
A holiday calendar of its own. The Fair Work Ombudsman's list of South Australian public holidays for 2026 includes Adelaide Cup Day on 9 March, part-day holidays from 7 pm to midnight on 24 and 31 December, and the Proclamation Day holiday on Saturday 26 December, with an additional public holiday on Monday 28 December. What an employee is paid for those hours depends on their award or agreement, so a bookkeeper who runs pays for restaurants, shops or care providers works through them every year. If that's you, the payroll page is the place to say it.
Where your clients are, and where we are. Name the suburb you work from and the areas you visit, whether that's Elizabeth and the rest of the City of Playford, Norwood and the eastern suburbs, or the Adelaide Hills and the Fleurieu, then explain how clients further out send their paperwork and meet with you online. Working from home, you can give the suburb and leave the street off. As for us, we're at Ste 3/110 Hutt St in the city, so there's no time difference to plan around. Most projects run by phone and email even so, which lets you check a draft between client files, and if you'd rather sit down before work starts, call and we'll arrange it.
