Australian Business Register

Quick Answer

Foreign subsidiaries in Australia must maintain financial records for at least 5 years under the Corporations Act 2001. This includes transaction records, bank reconciliations, GST tracking for BAS lodgement, and monthly management reports. Most foreign companies use Xero or MYOB with cloud access. A registered BAS agent can prepare and lodge your BAS quarterly. Bookkeeping services for foreign companies start from $500/month.

Bookkeeping Services

Foreign companies operating in Australia must maintain accurate financial records that satisfy Australian Taxation Office (ATO) requirements, GST reporting obligations, and Corporations Act standards. Australian bookkeeping rules differ from those in the US, UK, Europe, and Asia in areas including BAS lodgement cycles, GST treatment categories, and single-touch payroll integration. Australian Business Register provides dedicated bookkeeping services for international businesses, ensuring your Australian financial records are accurate, current, and fully compliant with local regulations from your first transaction.

ATO Record-Keeping Requirements for Foreign Companies

The ATO imposes specific record-keeping obligations on all businesses operating in Australia, including foreign entities. These requirements carry legal weight, and failure to maintain proper records can result in penalties, estimated tax assessments, and loss of input tax credit entitlements.

Mandatory Record Retention

Under the Income Tax Assessment Act 1997 and the Taxation Administration Act 1953, all business records must be kept for a minimum of five years from the date of the relevant transaction or the date the record was prepared, whichever is later. Records must be in English or readily convertible to English, and they must explain all transactions in enough detail to determine the company’s tax obligations. The ATO can issue penalties of up to $1,110 per failure for inadequate record keeping, and in serious cases, penalties can reach 75% of the tax shortfall resulting from poor records.

GST Registration and Reporting

Foreign companies with an Australian GST turnover exceeding $75,000 per annum (or $150,000 for non-profit bodies) must register for GST. Once registered, your bookkeeping must track GST collected on sales and GST paid on purchases across four categories: GST-free supplies, input-taxed supplies, taxable supplies, and out-of-scope supplies. Incorrect GST categorisation results in either overpayment of GST (reducing your cash flow) or underpayment (triggering ATO penalties and interest).

Business Activity Statements (BAS)

BAS lodgement is the primary reporting mechanism for GST, PAYG withholding, PAYG instalments, and other tax obligations. Lodgement frequency depends on your turnover:

  • Monthly BAS – Required for businesses with GST turnover of $20 million or more
  • Quarterly BAS – Standard for most businesses with turnover under $20 million
  • Annual GST Return – Available for voluntary GST registrations with turnover under $75,000

Quarterly BAS deadlines fall on the 28th of the month following each quarter (28 October, 28 February, 28 April, and 28 July). Late lodgement attracts a Failure to Lodge (FTL) penalty starting at $330 per 28-day period, up to a maximum of five penalty units. Late payment incurs interest charged at the General Interest Charge (GIC) rate, currently around 11% per annum.

Our Bookkeeping Services

Australian Business Register delivers bookkeeping solutions built specifically for foreign companies that need their Australian financial records managed by professionals who understand both ATO requirements and the reporting needs of overseas parent entities.

Transaction Processing

We process all financial transactions for your Australian operations, including sales invoices, purchase bills, expense claims, and inter-company transfers. Every transaction is coded to the correct chart of accounts category and GST classification. We reconcile bank accounts, credit cards, and payment platforms on a weekly or monthly basis depending on transaction volume. All entries follow Australian Accounting Standards (AASB) to ensure your records withstand ATO review.

BAS Preparation and Lodgement

Our team prepares your Business Activity Statements by reconciling GST collected and paid, calculating PAYG withholding amounts, and determining PAYG instalment obligations. We review every BAS before lodgement to identify unusual items, confirm GST treatment accuracy, and verify figures against bank statements. As registered BAS agents with the Tax Practitioners Board, we lodge directly with the ATO through approved electronic channels and manage payment timing to meet deadlines.

Bank Reconciliation

Monthly bank reconciliation confirms that your accounting records match actual bank transactions. We identify and investigate discrepancies, unmatched items, and timing differences. For foreign companies receiving transfers from overseas parent entities, we handle multi-currency reconciliation including foreign exchange gain/loss calculations required under AASB 121.

Accounts Receivable and Payable

We manage your customer invoicing process, track outstanding payments, and produce aged debtor reports for credit control. On the payable side, we process supplier invoices, verify GST components, schedule payments to meet terms, and maintain vendor records. For companies with Australian GST registration, we ensure all tax invoices meet the ATO’s requirements for valid GST claims.

Payroll Integration

Our bookkeeping service integrates with payroll processing to record wages, superannuation, PAYG withholding, and leave provisions accurately in your general ledger. Payroll journal entries reconcile with STP reports lodged with the ATO. For full payroll management, see our dedicated payroll services.

Month-End Close

We perform structured month-end procedures including accruals, prepayment amortisation, depreciation calculations, and inter-company balance reconciliation. Month-end reports are delivered within five business days of period close, giving your overseas management team timely visibility into Australian operations.

GST Compliance for Foreign Companies

GST compliance represents one of the most common areas where foreign companies make costly errors in Australia. The Australian GST system differs from VAT systems in Europe and GST systems in New Zealand and Singapore in several important ways.

Input Tax Credits

To claim input tax credits (ITCs) on GST paid on business purchases, you must hold a valid tax invoice from the supplier. Tax invoices have specific content requirements under Division 29 of the GST Act, including the supplier’s ABN, a description of the supply, the GST amount, and the date of issue. Tax invoices must be obtained before lodging the BAS in which the credit is claimed. Missing or non-compliant tax invoices result in denied ITC claims during ATO audits.

Mixed-Purpose Expenses

Where expenses relate to both taxable and GST-free or input-taxed activities, you can only claim input tax credits proportional to the taxable use. Foreign companies with mixed revenue streams must establish a fair and reasonable apportionment method and apply it consistently. Common methods include turnover-based allocation, floor-space apportionment, and time-based allocation.

Cross-Border Transactions

GST treatment of cross-border transactions requires careful analysis. Exports of goods are generally GST-free if the goods leave Australia within 60 days. Services provided to non-resident entities outside Australia are typically GST-free under the “connected with Australia” test. However, services connected with Australian real property, goods physically in Australia, or events in Australia remain taxable regardless of the recipient’s location. Our bookkeeping team applies the correct GST treatment to every cross-border transaction based on current ATO rulings.

Cloud Accounting Platforms

We work with the accounting platforms most commonly used by Australian businesses and preferred by the ATO for digital record keeping:

  • Xero – Our primary platform for small to mid-size operations, with strong bank feeds, BAS integration, and multi-currency support
  • MYOB – Suitable for businesses requiring payroll integration and industry-specific features
  • QuickBooks Online – Often preferred by US-based parent companies already using QuickBooks domestically

If your overseas parent company uses a different ERP system (SAP, Oracle NetSuite, Sage), we can maintain separate Australian books and provide consolidated reporting packages in your required format. We set up chart of accounts structures that map to your group reporting requirements while meeting Australian compliance standards.

Reporting for Overseas Parent Companies

Foreign companies need more than ATO-compliant records. Your head office requires financial information in formats that support group consolidation, management decision-making, and home-country reporting obligations.

Our standard reporting package includes:

  • Profit and Loss Statement – Monthly, with comparison to budget and prior year
  • Balance Sheet – Monthly, with inter-company balance detail
  • Cash Flow Statement – Monthly, highlighting operating, investing, and financing activities
  • GST Reconciliation – Quarterly, supporting BAS lodgement
  • Aged Receivables and Payables – Monthly, for working capital management
  • Bank Reconciliation – Monthly, confirming ledger-to-bank alignment

Reports can be delivered in AUD, your home currency, or both. We provide commentary on significant variances and flag items requiring management attention. For broader financial management support, our outsourced finance function extends beyond bookkeeping into management reporting, budgeting, and cash flow forecasting.

End-of-Year Compliance

Australian financial year-end (30 June) brings additional bookkeeping obligations that must be completed within specific timeframes.

Annual Tax Return Preparation

Your bookkeeping records form the basis for the annual company income tax return. We prepare all working papers, reconcile accounts, and deliver a complete set of financial statements to your tax agent. For companies using our taxation services, this handover is built into our standard process.

PAYG Payment Summary and STP Finalisation

Under STP Phase 2, employers must make a finalisation declaration to the ATO by 14 July each year, confirming that all payroll data reported during the financial year is complete and accurate. This replaces the old payment summary (group certificate) system. Our bookkeeping team reconciles payroll figures against STP reports to ensure the finalisation declaration is accurate.

Fringe Benefits Tax (FBT)

The FBT year runs from 1 April to 31 March, and the return is due 21 May. If your company provides any non-cash benefits to employees (cars, parking, entertainment, living-away-from-home allowances), our bookkeeping identifies and records these benefits throughout the year so your FBT return can be prepared accurately.

Getting Started

Setting up bookkeeping for your Australian operations follows a structured process designed to capture all necessary information and establish accurate records from day one.

Step 1: Scoping Meeting – We assess your transaction volume, complexity, reporting requirements, and existing systems. This determines the service level and pricing.

Step 2: System Setup – We configure your chosen accounting platform with an Australian-compliant chart of accounts, GST codes, bank feeds, and reporting templates aligned with your group structure.

Step 3: Historical Data Migration – If you have existing Australian records, we review and migrate them to the new system. We correct any GST classification errors and reconcile opening balances.

Step 4: Ongoing Processing – Regular bookkeeping commences with defined processing schedules, communication protocols, and reporting delivery dates.

Frequently Asked Questions

Do foreign companies need an ABN to operate in Australia?

Yes. Any foreign entity carrying on business in Australia must apply for an Australian Business Number (ABN). The ABN is required for GST registration, invoicing, and dealing with other Australian businesses. Without an ABN, other businesses must withhold 47% of payments made to you under the no-ABN withholding rules. See our ABN and GST registration services for assistance.

How often must BAS be lodged?

Most businesses lodge BAS quarterly, with deadlines on 28 October, 28 February, 28 April, and 28 July. Businesses with annual GST turnover of $20 million or more must lodge monthly. Voluntary registrations with turnover under $75,000 may lodge annually. Late lodgement attracts penalties starting at $330 per 28-day period.

What accounting standards apply in Australia?

Australian Accounting Standards (AASB) apply to financial reporting in Australia. These are based on International Financial Reporting Standards (IFRS) with some Australian-specific modifications. For foreign subsidiaries, financial statements may need to comply with both AASB standards for local reporting and the parent company’s home-country standards for consolidation purposes.

Can I claim GST on expenses incurred before registering for GST?

Yes, in certain circumstances. You can claim input tax credits for expenses incurred up to four years before your GST registration date, provided the expenses relate to your current business activities and you hold valid tax invoices. This applies to goods still on hand or consumed in making taxable supplies, and to services received within the four-year period.

Do I need to keep physical receipts?

No. The ATO accepts electronic records provided they are a true and clear copy of the original, stored securely, and accessible for the required retention period (five years minimum). Cloud accounting platforms with bank feed integration and attached digital receipts satisfy ATO requirements.

What is the difference between cash and accrual accounting for GST?

Under cash accounting, you report GST when payment is received or made. Under accrual accounting, you report GST when invoices are issued or received, regardless of payment timing. Businesses with turnover under $10 million can choose either method. Cash accounting can improve cash flow by deferring GST liability until you actually receive payment from customers.
