BAS Lodgement for Australian Businesses: What Indian CA Firms Need to Know

What is a Business Activity Statement (BAS)?

A Business Activity Statement (BAS) is a form submitted to the Australian Taxation Office (ATO) by registered businesses to report and remit various tax obligations. It is the primary compliance document for businesses operating in Australia and covers Goods and Services Tax (GST), Pay As You Go (PAYG) withholding, PAYG instalments, Fringe Benefits Tax (FBT), and other obligations — all in a single lodgement.

For Indian CA firms providing offshore accounting services to Australian clients, thorough understanding of BAS requirements is essential to deliver accurate, timely, and compliant work.

Key Components of a BAS

GST (Goods and Services Tax)

Australia's GST rate is 10%, applicable on most goods and services. The BAS reports total GST collected on sales (G1) and total GST credits (Input Tax Credits / ITCs) on purchases (G11). The net GST payable or refundable is the difference. Accurate coding of transactions in Xero, MYOB, or QuickBooks is critical — wrong tax codes are the most common source of BAS errors.

PAYG Withholding

Businesses that employ staff must withhold tax from salaries and wages and remit this via BAS. The amount withheld (W2) must match payroll records. Errors here attract ATO penalties and can affect employee tax refunds.

PAYG Instalments

Businesses above a certain income threshold pay income tax in instalments (T4/T7 on BAS). These are either ATO-calculated amounts or can be varied if the business's actual income differs significantly from the prior year.

Superannuation

While Super is not reported on BAS, it is closely linked — payroll run for BAS periods must correctly calculate Super Guarantee (currently 11.5% of ordinary earnings) to avoid SGC charges, which are non-deductible and carry significant penalties.

Lodgement Frequency

Monthly: Businesses with GST turnover of AUD 20 million or more
Quarterly: Most small to medium businesses (most common)
Annually: Businesses with turnover below AUD 75,000 (optional GST registration)

Quarterly BAS deadlines typically fall on the 28th of the month following the quarter end (October, February, April, July), with a two-week extension for lodgements made via a registered BAS agent or tax agent.

Why Outsource BAS Preparation to India?

The time zone difference between India (IST) and Australia (AEST/AEDT) allows Indian teams to work overnight Australian time — meaning deliverables are ready when the Australian principal starts their day. Combined with significantly lower staffing costs (typically 60–70% less than equivalent local hires), offshore BAS preparation gives Australian accounting firms a margin advantage without compromising quality.

Our team at G. S. SONPAL & ASSOCIATES has worked with Australian clients across retail, hospitality, professional services, and construction sectors. We are cloud-accounting proficient and follow ATO-compliant processes for every engagement.
