GST & BAS Compliance

Every lodgement reconciled. Every credit claimed. Every deadline met.

GST is one of the most frequently lodged compliance obligations a business has — and one of the most commonly done with errors that accumulate over time. The ATO’s systems automatically compare BAS lodgements against income tax returns. Discrepancies get flagged.
At Pinnacle Advisors Services, every BAS is prepared by a Registered BAS Agent — reconciled against your accounting records, reviewed for missed credits, and lodged correctly every period.

Who this is for

Any business with employees or contractors. Businesses setting up payroll for the first time. Businesses that have been running payroll themselves and want a qualified review. International businesses with Australian staff. Businesses with complex award or enterprise agreement arrangements.

Our Services In Detail

Compliance Handled. Completely.

BAS & IAS

Every lodgement reconciled. Every figure verified. Every deadline met.

Every activity statement we prepare is reconciled against your accounting records, reviewed for missed credits, and lodged on time — by a Registered BAS Agent, every period. We handle everything from standard monthly and quarterly lodgements to PAYG variations, prior period corrections, and overdue catch-up. No shortcuts. No unclaimed credits. No surprises from the ATO.

Who this is for

Any business registered for GST lodging monthly, quarterly, or annual activity statements — including businesses that have been self-lodging and want a compliance review, and those with overdue lodgements needing catch-up.

What we handle

One thing to know

The ATO’s systems automatically compare your BAS lodgements against your income tax return. If your GST-exclusive income does not reconcile, it generates a risk flag. We reconcile every lodgement against your records — because the flag is entirely avoidable.

GST Advisory & Registration

GST obligations understood. Registrations done correctly. Complex matters handled.

From registration through to ongoing advisory, we handle the full scope of GST obligations — including non-standard transactions, mixed-use assets, GST-free and input-taxed supply classifications, and foreign businesses with Australian sales. Every position we take is grounded in the legislation and reviewed for compliance.

Who this is for

Businesses with non-standard GST transactions, foreign businesses selling digital services or goods into Australia, businesses in healthcare, education, or financial services with mixed supply classifications, and any business that has never had a formal GST compliance review.

What we handle

GST registration for Australian businesses and foreign entities
GST registration for non-residents selling digital services into Australia
ABN registration for Australian and foreign entities
TFN registration on behalf of clients
Advising on GST obligations, liabilities, and entitlements
Input tax credit claims and advice
GST-free supply classification — healthcare, education, food
Input-taxed supply classification — financial services, residential rent
GST advisory on complex transactions — property, mixed-use assets, insurance recoveries
GST for non-residents — digital services, imported goods, foreign businesses
Fuel tax credit (FTC) registration and ongoing claims
LCT and WET registration and compliance
GST health check — reviewing self-lodged returns for errors and missed credits
Compliance system design for GST obligations
Advising how GST law affects business operations

One thing to know

For foreign businesses selling digital services into Australia, GST registration is required from the first dollar of Australian sales — there is no $75,000 threshold. Many foreign businesses are operating with an unregistered GST obligation. We identify and resolve this before it becomes an ATO matter.

ATO Representation — BAS & GST

You deal with us. We deal with the ATO.

Receiving something from the ATO — a data-matching notice, a request for information, a compliance review, or an audit — is not something to handle alone or slowly. On BAS, GST, payroll, and superannuation guarantee matters, Pinnacle Advisors represents you directly as your Registered BAS Agent.

Who this is for

Businesses that have received ATO correspondence on BAS, GST, payroll, or SGC matters. Businesses that want to proactively correct prior period errors. Businesses with overdue lodgements. Foreign entities under ATO review for Australian GST obligations.

What we handle

ATO queries and information requests on BAS provisions — reviewed, interpreted, and responded to on your behalf
GST compliance reviews and audits — full preparation, documentation, and representation
SGC audits — ATO representation throughout, including payment arrangements and penalty remissions
Payroll compliance reviews on BAS provision matters
Responding to ATO risk assessments and data-matching notices
Penalty remission requests — where penalties have been imposed and circumstances support remission
Interest remission requests on BAS-related liabilities
Payment arrangement negotiations — structured arrangements where liabilities create cash flow pressure
Voluntary disclosures — correcting GST and payroll errors before the ATO finds them, which significantly reduces penalties
Overdue BAS lodgement catch-up — working through the backlog with a plan
ATO representation for non-resident and foreign entities on Australian BAS matters

One thing to know

The ATO applies significantly lower penalties to businesses that come forward proactively compared to those identified through audit. Voluntary disclosure is not an admission — it is a strategy. And on every BAS, GST, payroll, and SGC matter, Pinnacle represents you directly. You do not need to talk to the ATO. We do that.
