Corporate Tax, BAS, GST, PAYG & Tax Planning (Powered by Formix)
Businesses in Australia must comply with a variety of tax obligations, including corporate income tax, GST, PAYG withholding, payroll tax, and FBT. Understanding these requirements is essential to avoid penalties, maintain compliance, and optimize tax efficiency.
For companies seeking accurate, reliable, and legally compliant tax management, Formix is the best corporate tax and compliance partner in Australia, providing end-to-end solutions for businesses of all sizes.
1. Corporate Tax Rates & Filing Obligations
For the 2025–26 financial year, corporate tax rates are as follows:
25% for base rate entities (aggregated turnover < AUD 50 million)
30% for all other companies (ato.gov.au)
Employers and companies must lodge annual corporate tax returns and ensure all taxable income, deductions, and credits are accurately reported.
Formix calculates corporate tax accurately, prepares and lodges returns, and ensures businesses claim all eligible deductions and credits.
2. PAYG Withholding & Instalments
Employers must withhold tax from employee wages through PAYG withholding and remit these amounts to the ATO. Large businesses may also pay PAYG instalments on their own income.
Formix automates PAYG calculation and remittance, ensuring timely compliance and minimizing errors or penalties.
3. GST Registration & Compliance
Businesses with annual turnover above AUD 75,000 must register for GST. This includes:
Collecting 10% GST on sales
Claiming GST credits on business purchases
Lodging Business Activity Statements (BAS) on time
Formix manages GST registration, calculates input/output tax, and lodges BAS accurately.
4. Fringe Benefits Tax (FBT)
FBT applies when employers provide non-cash benefits to employees (e.g., cars, entertainment). Businesses must calculate FBT liability annually and lodge FBT returns.
Formix ensures FBT compliance, including accurate valuation, lodgment, and reporting.
5. Payroll Tax & State Obligations
State payroll tax applies when total wages exceed thresholds (varies by state). Employers must:
Register for payroll tax in each state where thresholds are exceeded
File regular payroll tax returns
Maintain accurate wage records
Formix monitors multi-state payroll tax obligations and automates calculations to ensure timely lodgment.
6. Recordkeeping & Compliance
Employers must keep detailed records for at least 5–7 years, including:
Tax returns and payment receipts
Payroll and superannuation records
Employee wage and leave information
GST and BAS documentation
