Payday Super became mandatory for law firms and other service businesses on 1 July 2026 — and if you run a solicitors’ practice, conveyancing firm, or any other client-facing business with staff, it’s already changed how money moves through your business, whether you’ve noticed it yet or not.
The headline change is simple: superannuation guarantee (SG) contributions now need to reach your employees’ super funds within 7 business days of each payday, rather than quarterly. New employees, or a first payment into a new fund, get a slightly longer 20 business day window. The ATO retired the Small Business Superannuation Clearing House for payments from 1 July 2026 onwards — replace it now if it was part of your process.
For a lot of businesses, that’s a payroll admin change. For client-facing service businesses, it’s something more — it’s a cash flow change.
The timing mismatch service businesses feel first
Firms like yours don’t get paid the moment work is done. You accumulate WIP as unbilled, send invoices out on 30- or 60-day terms, and — for solicitors in particular — hold client funds in trust that you can’t touch for operating costs at all. Meanwhile, payroll and super now move on a fixed, frequent clock: every payday, every 7 days.
Under the old quarterly system, the quarterly cycle cushioned that mismatch. You had roughly three months to fund super, even if a big invoice was running late. That buffer is gone. Now, if a client payment slips a week, it can land in the same week your super obligation is due — and unlike a supplier you can negotiate with, the ATO’s timeline doesn’t bend.
What happens if the timing doesn’t work
Missing the 7-day window isn’t just a late fee. It triggers the SG Charge, which the ATO calculates on your employee’s ordinary time earnings, plus daily compounding interest from the missed due date, plus an administrative uplift that can add up to 60% on top. If it’s still unpaid 28 days after the ATO notifies you, a further penalty of 25%, or 50% for repeat non-compliance, can apply. The interest and penalties are not tax deductible.
The ATO said it’s taking an education-focused, risk-based approach in this first year, prioritising employers who aren’t making a genuine effort over those who are. That’s worth knowing — but it’s a soft landing, not a free pass. The habits you build now are the ones that matter once that grace period ends.
What this means in practice
A few things are worth checking now, not at your next BAS:
- Forecast super as a per-payday cost, not a quarterly one. If you’re still budgeting for super in a lump sum every three months, rebuild that forecast around your actual pay cycle. It’s a small mental shift with a real cash flow impact.
- Look at your billing cycle alongside your pay cycle. If invoices go out monthly but you pay staff fortnightly, there will be weeks where super is due before the cash to cover it has landed. Knowing exactly when those weeks fall — before they arrive — is the whole point of doing this now rather than reactively.
- Confirm you’ve set up your payroll software for weekly compliance, rather than leaving it on its old quarterly default, and that you have a compliant clearing house or direct-to-fund process now that SBSCH is gone.
- Keep a short cash buffer specifically for super, sized to your worst-case billing lag rather than your average one. Firms with irregular client billing — which describes most solicitors and conveyancers — are exactly the businesses this reform affects most.
The bigger picture
This is the same theme we keep coming back to on Payday Super for law firms and other service businesses: profit on paper and cash in the bank are two different things, and the gap between them is where financial stress actually lives. Payday Super hasn’t created that gap — it’s just made it show up faster and more often.
If you’d like a hand mapping your pay cycle against your billing cycle to see exactly where the pressure points sit, that’s a conversation worth having before your next pay run, not after a missed one.
