For many Perth business owners, tax planning becomes a priority only when the end of the financial year approaches. Receipts are collected, expenses are reviewed and accountants are contacted to prepare the annual tax return. Waiting until June, however, limits the time available to understand obligations, assess decisions and prepare for upcoming payments.

Business tax planning in Perth involves reviewing income, expenses, tax obligations and significant business decisions throughout the financial year. A year-round approach helps owners estimate future liabilities, assess eligible deductions, prepare for GST and PAYG payments, and make informed decisions before important transactions occur.

Proactive planning is not simply about paying less tax. It is about understanding financial responsibilities and managing them in line with Australian taxation law. This guide explains how to build a practical year-round process, including a July-to-June calendar, financial review strategies and examples for Perth businesses.

What Is Business Tax Planning in Australia?

Business tax planning is the process of assessing a business's financial position and considering the tax implications of its activities and decisions. It may involve reviewing expected income, operating expenses, asset purchases, business structures, tax payments and future commitments. The aim is to understand potential tax consequences before decisions are finalised.

For example, a Perth construction business planning to buy equipment may need to understand the depreciation treatment and cash flow implications. A consulting company expanding its workforce may need to consider payroll, PAYG withholding and employer superannuation obligations.

An accountant can help assess the relevant tax rules, but the business owner must still provide accurate information and make commercial decisions based on their circumstances.

Business Tax Planning vs Tax Compliance

Tax planning and tax compliance are closely connected, but they serve different purposes. Compliance means meeting reporting and payment obligations under taxation laws. Planning considers the implications of business activities before or during the relevant period.

Business tax planning	Business tax compliance
Reviews expected income and expenses	Reports historical financial information
Considers future transactions	Prepares required tax returns
Estimates potential tax liabilities	Meets lodgement obligations
Assesses business decisions	Reports GST, PAYG and other required amounts
Supports financial planning	Maintains accurate tax reporting
Can occur throughout the year	Follows set reporting periods

Both are important. A business may lodge its returns correctly but still experience cash flow problems if it has not prepared for the resulting payments. Equally, tax planning cannot replace accurate record keeping or statutory compliance.

1. Start the Financial Year With a Clear Tax Position

A practical tax planning process begins with understanding the previous year's performance. Review financial statements, completed tax returns and any outstanding reporting matters. Useful starting points include:

previous financial year revenue and operating expenses
accounting profit and relevant tax adjustments
outstanding tax liabilities
GST and BAS balances
PAYG instalments
business asset records
expected business changes

Example: a Perth professional services firm. Suppose a consulting company experienced strong revenue growth last year. Its owners expect further growth but have not updated their tax payment forecasts. Reviewing the previous results and current contracts may show that estimated income tax payments need closer attention, and when funds should be set aside to meet them.

2. Create a July-to-June Tax Planning Calendar

Australian businesses generally operate on a financial year from 1 July to 30 June, although approved substituted accounting periods apply to some entities. A planning calendar helps owners organise regular reviews instead of postponing everything until year-end.

Month	Suggested tax planning activity
July	Review prior-year results, new tax rules and budgets
August	Reconcile opening balances and outstanding tax matters
September	Update income forecasts and expected tax liabilities
October	Review GST, BAS, PAYG and record-keeping processes
November	Assess profitability, operating expenses and cash flow
December	Complete a mid-year tax and financial review
January	Reforecast revenue, expenses and expected tax payments
February	Review planned investments and financing
March	Identify matters needing attention before 30 June
April	Review asset records, deductible expenses and evidence
May	Discuss year-end tax considerations with an adviser
June	Finalise planning decisions and prepare accurate EOFY records

This is a suggested management schedule, not an ATO lodgement calendar. Actual BAS, tax, payroll and payment deadlines depend on each business's circumstances. Businesses with higher transaction volumes or complex reporting may benefit from more frequent reviews.

3. Review Income and Expected Taxable Profit Regularly

Revenue growth is usually positive, but it can also change a business's expected tax position. A business that secures several new contracts may earn more taxable income than forecast, and owners without an updated plan may underestimate future obligations.

Compare actual revenue against budget and check whether expenses are rising at the same rate. Review significant changes in contracts, sales, staffing and operating costs. Remember that accounting profit and taxable income are not the same, because tax adjustments can affect the final result.

Practical example. A Perth company initially forecasts $120,000 in accounting profit before tax. After several new contracts, the forecast rises to $185,000. The increase may affect its expected income tax, PAYG instalments and cash needs. Updating the forecast during the year lets management prepare rather than discover the difference after year-end.

4. Understand GST and BAS Obligations

Businesses generally must register for GST when their GST turnover reaches, or is expected to reach, $75,000, subject to the applicable rules and exceptions. GST turnover is not the same as profit.

A business may need to review regularly:

taxable and GST-free sales
eligible GST credits on purchases
correct tax invoice records
BAS reconciliations
changes in turnover

Example: a growing Perth online retailer. An online store starts with modest monthly sales. As orders increase, the owner needs to watch whether GST registration becomes compulsory. Waiting until the annual tax return may be too late. Regular turnover reviews help the business spot the change in time.

GST planning should also account for expected payments and refunds, rather than treating GST collected as spare business cash.

5. Plan for PAYG Instalments and Employer Obligations

PAYG instalments and PAYG withholding serve different purposes. PAYG instalments are generally prepayments towards income tax on business or investment income. PAYG withholding generally involves withholding amounts from payments such as wages and sending them to the ATO.

Businesses that receive instalment notices should check whether the amounts reasonably reflect their expected income tax position. The ATO allows instalments to be varied where appropriate, but variations must follow the rules, and underestimating can lead to extra charges.

Employer superannuation. Businesses with employees also need to build super into their forecasts. From 1 July 2026, Payday Super requires employers to pay super at the same time as wages, with contributions generally needing to reach the employee's fund within seven business days. A longer window applies to a new employee's first contribution. The super guarantee rate is 12% of qualifying earnings. Make sure payroll software, payment processes and cash forecasts reflect these requirements, and check current guidance from the ATO.

6. Review Business Expenses and Eligible Deductions

Expense management should happen throughout the year, not only when the tax return is prepared. Businesses can generally claim eligible expenses incurred in earning assessable income, subject to the tax rules. Expenses with private use, capital purchases and certain restricted items may need closer assessment.

Common categories include commercial rent, business insurance, accounting fees, advertising, software and eligible employee costs. A business should not assume that:

every payment from its bank account is deductible
every asset purchase can be claimed immediately
private expenses become deductible when the company pays them
a deduction reimburses the full purchase cost
missing records can always be replaced by estimates

Keeping invoices, receipts and supporting documents throughout the year reduces problems at reporting time.

7. Consider Asset Purchases Before Committing Funds

Buying machinery, vehicles or equipment affects both accounting records and tax calculations. Some assets are depreciated over time, while specific concessions may apply when eligibility requirements are met, and these rules can change between income years.

Example: a Perth trade business. An electrical contractor is considering $38,000 of new equipment. Before buying, the owner should assess whether it is commercially necessary, how it will be financed and what deduction treatment applies, including when it will be ready for use and whether any concession requirements are met. A purchase should never be made only because it might create a deduction.

8. Connect Tax Planning With Cash Flow Management

Tax payments create pressure when businesses do not anticipate them. A company may report a profit yet have little cash if customers have not paid their invoices. A useful cash flow forecast includes expected GST, PAYG, income tax and other commitments.

Cash flow item	Amount
Opening cash balance	$45,000
Expected customer receipts	$80,000
Supplier and operating payments	−$55,000
Payroll and superannuation payments	−$35,000
Planned tax payments	−$15,000
Forecast closing cash	$20,000

This hypothetical business expects to finish the month with $20,000, but delayed customer receipts could change that quickly. That is why tax planning works best alongside cash flow forecasting rather than separately.

9. Review Business Structures Before Significant Changes

A business's structure affects its accounting and tax obligations. Sole traders, partnerships, companies and trusts have different reporting arrangements. Consider reviewing the structure before:

introducing new owners
expanding into new activities
buying or selling significant assets
restructuring operations
changing how owners are paid

Changing structures can involve income tax, capital gains tax, GST, duty and legal issues, so professional tax and legal advice may be needed first. No structure is the most tax-effective for every business.

10. Practical Examples for Perth Businesses

Example A: a Perth IT consulting business. The company starts the year expecting moderate growth. By December it has secured several extra contracts, and its profit forecast rises significantly. It updates its cash flow forecast, reviews PAYG instalments and reconsiders upcoming spending, identifying its commitments while there is still time to prepare.

Example B: a Perth construction company. Before hiring more workers and buying equipment, management reviews projected project revenue, staffing costs, financing and tax considerations. It also checks GST reporting and super processes. The resulting plan shows whether the expansion is affordable.

Neither scenario guarantees a particular tax saving. The benefit is clearer information before decisions are made.

11. Common Year-Round Tax Planning Mistakes

Waiting until the final month, which limits options and increases pressure
Ignoring changes in profitability, so forecasts become outdated
Confusing profit with available cash, leaving too little for tax payments
Buying only for deductions, when a deduction reduces taxable income rather than recovering the full cost
Overlooking GST and PAYG, since income tax is only one obligation
Failing to keep records, making it hard to support deductions

The simplest way to avoid these is to review financial information regularly and investigate unusual changes before deadlines arrive.

12. How Can a Business Accountant Help?

Some owners manage routine financial administration themselves. Professional support becomes more useful when a business has complex transactions, changing income or major decisions ahead. A registered tax agent can help review expected liabilities, assess deductions, explain GST and PAYG obligations and consider the tax implications of planned activities.

Frequently Asked Questions

What is business tax planning?

It is the process of reviewing a business's income, expenses, tax obligations and decisions to understand their tax implications, so owners can estimate liabilities and prepare for future commitments under Australian tax law.

When should a Perth business start tax planning?

At the start of the financial year, with regular reviews after that. Important decisions are best assessed before transactions occur, not in June.

Is tax planning different from preparing a tax return?

Yes. Planning looks ahead at future transactions and obligations, while tax return preparation reports income, deductions and other information for a past income year.

Can tax planning legally reduce business tax?

It can help identify eligible deductions and available concessions, but outcomes depend on circumstances, eligibility and legislation. No particular saving is guaranteed.

Does a small business need tax planning every month?

Not necessarily a monthly meeting with an accountant, but regular financial reviews help catch changes early. The right frequency depends on the business's complexity.

How does tax planning help cash flow?

It helps estimate upcoming GST, PAYG and income tax payments so they can be included in cash flow forecasts.

What records matter most?

Sales invoices, expense receipts, bank statements, BAS reports, payroll information, asset registers and financial statements, kept for the periods required in Australia.

Can an accountant help with business tax planning?

Yes. A registered tax agent can assist within their permitted scope, including reviewing expected obligations and planned transactions.

Conclusion: Make Tax Planning Part of Regular Business Management

Business tax planning should not be limited to the weeks before 30 June. Regular reviews give Perth business owners a clearer view of income, expenses, tax obligations and future commitments.

A practical year-round approach means reviewing results, monitoring GST and PAYG, keeping accurate records and assessing major decisions before they happen, all alongside cash flow and long-term goals. With a consistent review process and suitable advice when needed, Perth businesses can approach their tax responsibilities with greater confidence.
