What is bas preparation?

The Business Activity Statement prepared from reconciled GST control accounts — lodgment-ready for your registered agent, every cycle.

The BAS is not a GST form with extra fields bolted on — it is the single periodic return most Australian businesses deal with the ATO through. GST collected and GST credits claimed sit on it alongside PAYG withholding on staff wages, PAYG instalments toward the year-end income tax bill, and, for the businesses that carry it, FBT instalments. One statement, one due date, one net figure owing or refundable. There is no separate GSTR-1/GSTR-3B split the way India runs it — the outward-supply detail and the summary-and-payment step are the same form, the same lodgment.

What lands on the BAS is only as good as the ledger it comes from. Every sale needs the right GST tax code (GST, FRE, INP, EXP, GNR, N-T, and the rest, depending on the accounting package), every purchase needs its GST credit correctly claimed or excluded, and the GST control accounts — GST collected, GST paid — need to tie to the transaction detail behind them, not just to a number that happens to balance. A BAS pulled from an unreconciled file can be arithmetically consistent and still wrong, because a wrongly coded transaction nets out somewhere else on the same statement.

BAS preparation in Australia

TASA 2009 s.90-10 defines what a "BAS service" is, and preparing one for a fee sits inside it

Section 90-10 of the Tax Agent Services Act 2009 defines a BAS service as, broadly, any service that relates to ascertaining or advising about liabilities, obligations or entitlements under a BAS provision, or representing a client to the Commissioner in relation to one, done for a fee or other reward. GST registration, BAS and IAS preparation and lodgment, and dealing with the ATO on a client's GST affairs all fall inside that definition. Only a person or firm registered with the Tax Practitioners Board as a BAS agent or tax agent may provide a BAS service for a fee — CapEasy prepares the reconciled figures and the workpapers behind them; your registered BAS or tax agent is the one who reviews, ascertains what goes on the statement, and lodges it.

GST tax codes decide what lands on each BAS label — the amount alone tells you nothing

A transaction's dollar value is identical whether it's coded GST, FRE or INP; what changes is which BAS label it flows to and whether a GST credit is claimed on it. A purchase coded GST when the supplier actually charged no GST overstates the credit claimed on label 1B; a sale coded FRE when it should carry GST understates GST collected on label 1A. We reconcile every transaction's code against its source document before it feeds a BAS figure, and flag anything the code and the description disagree on.

The GST control accounts have to tie out, not just look plausible

GST Collected and GST Paid (or their equivalent accounts, however the ledger names them) are control accounts — every dollar in them should trace back to an individual transaction with a tax code attached. A control account that balances to a round number without every line reconciled against a bank statement or invoice is a sign the file was adjusted to fit, not built from source documents. Our handoff pack ties the control accounts to the transaction detail behind them, so your agent is reviewing a reconciliation, not taking a number on faith.

Monthly BAS has no extension; quarterly has one, but only if you were already on an agent's books

The 21st-of-the-month monthly BAS deadline applies to everyone, self-lodging or agent-lodged, with no extension mechanism at all. Quarterly due dates (28 Oct, 28 Feb, 28 Apr, 28 Jul) do carry an agent-lodgment extension of roughly four weeks, but the ATO only grants it where the client was already engaged with the registered agent ahead of the original due date and the agent's other lodgment obligations for that client are current — it is not something a late-arriving client can retroactively claim on the deadline that's already passed.

What your registered BAS or tax agent receives from us

  • A GST tax-code reconciliation for the period — every sale, purchase and adjustment grouped by code (GST, FRE, INP, EXP, GNR, N-T) and matched to its source document.
  • The GST Collected and GST Paid control accounts reconciled to the transaction detail behind them, tied to bank statements for the period.
  • A draft BAS figure set mapped to each ATO label — G1 total sales, G3 GST-free sales, G10/G11 acquisitions, 1A GST on sales, 1B GST on purchases — ready for review.
  • PAYG withholding figures for the period reconciled to pay runs processed, where the client also runs payroll through the period.
  • PAYG instalment figures carried forward at the rate or amount the ATO has notified for the period, checked against the client's current instalment notice.
  • An exception log flagging any transaction where the GST code looked inconsistent with the account, the description, or the supplier it was matched against.

Questions worth asking before you start

Who actually does the work — a person or an AI tool?

A named person on our team owns your file and reviews everything that leaves it. Software does a real share of the grinding underneath it — coding, matching, flagging the obvious gaps — but nothing regulated happens without a person’s judgement, and nothing here is signed or filed by an algorithm.

Who can legally lodge this?

Your registered BAS or tax agent lodges; CapEasy prepares the reconciled file they lodge from. TASA 2009 draws this line and we build to it.

Which software do you work in?

Whatever you already run. Most commonly QuickBooks, Xero, NetSuite, Sage, Zoho Books and a handful of others — we work inside your system rather than moving you onto one of our own.

How does this actually start?

A short, free read-only look at what you already have, and a written note on what we found. A scoping call decides the size of the engagement — nothing here commits you to anything.

What does it cost?

There is no published price for bas preparation — it depends on volume, how many entities are involved, and how far behind the books are. We quote after the read-only review, which is free.

How does this fit with the rest of gst & bas?

BAS preparation sits inside gst & bas, alongside GST registration, IAS preparation, GST review & notice support. Most clients end up buying the category as a whole rather than one leaf at a time, but starting narrow is fine.

Does CapEasy lodge our BAS?

No. CapEasy reconciles your GST control accounts and prepares the BAS figures. Your registered BAS or tax agent reviews them and lodges the statement under their Tax Practitioners Board registration — that's the line TASA 2009 s.90-10 draws, and it applies to any service that ascertains or advises on a BAS obligation for a fee.

Why can't CapEasy just lodge it for us directly?

Because preparing or lodging a BAS for a fee is legally defined as a "BAS service" under the Tax Agent Services Act 2009, and only a person or firm registered with the TPB as a BAS or tax agent may provide one for a fee. CapEasy prepares the reconciled file and hands it to your registered agent to lodge.

What exactly do you hand over to our BAS agent?

A reconciled workpaper pack: GST tax codes matched to source documents, the GST control accounts tied to transaction detail, draft figures mapped to each BAS label, and an exception log of anything that looked inconsistent. Your agent reviews that pack rather than starting from a raw, unreconciled ledger.

How often is our BAS due?

Depends on your assigned cycle. Monthly if GST turnover is $20 million or more, due the 21st of the following month with no extension for anyone. Quarterly by default below that, due 28 October, 28 February, 28 April and 28 July for self-lodgers. Annual only if you're voluntarily registered under the $75,000 ($150,000 not-for-profit) threshold and elect it.

Can a registered agent get us more time to lodge?

On quarterly cycles, yes — roughly an extra four weeks on most due dates — but only if you were already on the agent's books ahead of the original due date and your other lodgments with them are current. Monthly BAS has no extension mechanism at all, for anyone.

What happens if we lodge late?

The Failure to Lodge penalty is $364 per 28-day period overdue for a small entity, capped at five periods, plus General Interest Charge on any GST actually owing. A late lodgment can also hold up processing of a GST refund for that period.

What are GST tax codes and why do they matter more than the dollar amount?

Codes like GST, FRE, INP, EXP, GNR and N-T route a transaction to a different BAS label regardless of its dollar value — the same $1,000 sale reports completely differently depending on which code it carries. We check the code against the source document for every transaction that feeds a BAS figure.

What if we find an error in a BAS we already lodged?

Small errors under the ATO's dollar thresholds can often just be corrected on the next BAS. Larger errors need a formal revision, generally available within two years of the original lodgment. Which route applies is a judgement call your registered agent makes; we document the correction and the reason either way.

Do you also handle our IAS?

The Instalment Activity Statement, for the cycles a business lodges one between BAS periods, is prepared on the same reconciliation discipline as the BAS — that's a separate leaf in our GST & BAS group, and it hands off to your registered agent the same way.

What access do you need to prepare our BAS?

Read access to the accounting file (Xero, MYOB, QuickBooks or equivalent) at the permission level the reconciliation requires, plus bank statements for the period. The file, the subscription and the lodgment relationship with your agent all stay yours.

What if we don't already have a registered BAS or tax agent?

We can introduce you to one as part of setting up the workflow — the reconciled pack we prepare is built to hand straight to a TPB-registered agent, whether that's one you already work with or one we connect you with.
