Quarterly BAS without the quarterly stress.
BAS and GST prepared, reconciled against your books, and lodged direct to the ATO. PAYG instalments managed alongside.
Three reasons our clients stay.
We’re a boutique accounting practice built on long-term client relationships, offering personalised tax, accounting, and advisory services to businesses and organisations across Sydney.
Twenty-three years in practice as of 2026. Same firm, same principal, same standards since 2003. Some clients have been with us almost the whole way. The work compounds, and so does the trust. Over four hundred SMSFs managed and thousands of tax returns lodged.
Tax, books, advisory, SMSF, Xero. One team that knows your business. No handoffs between firms, no missed details between specialists, no questions you have to answer twice. Numbers flow cleanly from books to BAS to tax return because the same people are looking at all of them.
We are old-fashioned about this. You get a name, a direct line, and someone who actually knows your file. We watch for trends, flag issues before they become fines, and call when something needs attention. Most clients hear from us between quarters, not just at lodgement time.
BAS lodged on time, then reconciled afterwards.
Quarterly BAS rolls around. Numbers come out of Xero. The form gets lodged. Done.
Then six months later, year-end accounts are prepared. The bookkeeper realises GST coding was wrong on a few line items. PAYG was overstated for two months. Some sales went to the wrong category. The BAS that lodged on time was technically wrong, and now there is a revision to file, possibly an interest charge.
BAS done well is reconciliation first, lodgement second. The order matters. When reconciliation feels optional because the form is overdue, errors slip through. Trinity reconciles before the BAS leaves the desk: bank feeds matched, GST coded properly, PAYG checked against the prior period.
Reconciliation first, BAS second.
BAS prepared, reconciled against your books, and lodged direct to the ATO. PAYG instalments managed alongside. On time, every quarter, since 2003. The list below is what we run on a quarterly cycle, every cycle.
A BAS that does not need revising.
Less time on admin. Cleaner records. Better decisions because the numbers are current.
Reconcile, lodge, track. Every quarter.
Same process for every new engagement. You know what is happening and when.
Books reviewed, transactions reconciled, GST coding verified line by line.
Form prepared, numbers cross-checked, draft sent to you for sign-off.
Sign-off, lodgement, ATO confirmation, and PAYG cash flow update.
Businesses we cycle with each quarter.
If you see your situation below, we have done this work before. If you do not, ask anyway.
A small firm by design.
Trinity Accounting Practice opened in Beverly Hills in 2003. Ramy Hanna, a registered tax agent and Fellow of three Australian accounting institutes, has run it since. The firm has stayed deliberately small, deliberately local, and deliberately senior. The principal you talk to today is the principal who will be reviewing your return next October.
Most of our work comes from referrals. Most clients have been with us for years, some for decades. We think that says more about the work than any award would.
The reviews speak for themselves.
Sole traders, growing companies, and trustees who keep coming back. Here’s why.

Common BAS and GST questions.
Quarterly cycles raise the same handful of questions across most clients. Here are the ones that come up most.
BAS preparation and lodgement is typically billed quarterly as part of an ongoing engagement. Standalone BAS work is quoted up front based on transaction volume and complexity.
Most small businesses lodge quarterly. The ATO requires monthly lodgement once turnover exceeds twenty million dollars, or voluntarily for cash flow reasons. We help you decide which suits your situation.
Yes. We lodge BAS across multi-entity groups, including consolidations where they apply. Each entity gets its own reconciliation and review.
Late lodgement attracts ATO penalties and interest. If you have come to us with overdue BAS, we work through them in order, request remission of penalties where reasonable, and put a lodgement schedule in place going forward.
The ATO sets PAYG instalments based on prior year tax, prepaid quarterly. We monitor whether the instalment matches your actual current-year position and vary it when warranted, so you do not overpay or face a year-end shortfall.
Not exactly. BAS reports GST, PAYG instalments, PAYG withholding, FBT, and a few other obligations. GST is one section of the BAS form.
