5 Tax Tips Small Businesses Need to Know in 2026

Tax time doesn’t have to be the stressful scramble it often turns into. With a bit of planning throughout the year, you can save real money and avoid headaches when the end of the financial year rolls around.

The truth is, most tax tips for small businesses come down to the same thing: know what you owe, know what you can claim, and keep your records in order. Good record-keeping is the foundation of managing your tax affairs well. Here are five practical tips that apply whether you’re a sole trader, running a company, or somewhere in between.

1.Understand Your Tax Obligations Before They Catch You Off Guard

One of the biggest mistakes small business owners make is not fully understanding what taxes apply to them. Your obligations depend on your business structure, and getting this wrong can be costly.

If you operate as a sole trader, your business income flows straight into your personal tax return. You pay tax at individual rates, which means everything from the tax-free threshold to the Medicare levy applies to your total taxable income.

If you run a company, your profits are taxed at the company tax rate. Base rate entities (aggregated turnover under $50 million, at least 80% active business income) pay 25%. All other companies pay 30%.

On top of income tax, you may also need to manage GST if your turnover is $75,000 or more, PAYG withholding if you have employees, and PAYG instalments if the Australian Taxation Office (ATO) has assessed you for regular pre-payments on your expected tax. Each of these has its own reporting deadlines and BAS obligations.

The takeaway: know which taxes apply to your specific structure. If you’re unsure, it’s worth speaking to a registered tax agent or getting professional tax advice early rather than sorting it out after a missed deadline.

2. Claim Every Deduction You Are Entitled To

Tax deductions reduce your taxable income, which directly lowers the amount of tax you pay. But you can only claim expenses that are genuinely related to earning your business income, and you need records to back them up.

Common deductions for small businesses include rent and utilities for your business premises, wages and superannuation for employees, accounting and bookkeeping fees, insurance premiums, marketing and advertising costs, software subscriptions, motor vehicle expenses, and travel expenses for business trips. If you earn investment income through the business, that may also come with its own deductible expenses.

If you work from home, you may also be able to claim a portion of your household running costs. The ATO offers a fixed-rate method or an actual cost method for home office deductions. Choose the one that gives you the better outcome and keep a record of hours worked.

The key is to claim everything you’re entitled to, but nothing you can’t justify. The ATO requires you to keep records for at least five years, and you must be able to provide evidence for every deduction if audited. That means receipts, invoices, or bank statements for every claim.

A good bookkeeper can help you identify deductions you might be missing and make sure your records are in order all year round, not just at tax time.

3. Make the Most of the Instant Asset Write-Off

The instant asset write-off is one of the most valuable tax concessions available to Australian small businesses. Instead of depreciating assets over several years, it allows you to claim the full cost of eligible depreciating assets in the financial year you purchase them.

For the 2025-26 financial year, small businesses with an aggregated turnover of less than $10 million can immediately deduct assets costing less than $20,000 each. The threshold applies per asset, so you can write off multiple purchases in the same year. Both new and second-hand assets qualify, as long as they are first used or installed ready for use before 30 June 2026.

This could include tools and equipment, computers, point-of-sale systems, motor vehicles (subject to the car limit for passenger vehicles), and office furniture.

One important detail: the asset must be delivered and operational by 30 June. Ordering before that date isn’t enough. Allow lead time for delivery and setup.

It is also worth noting that this $20,000 threshold has been extended on a year-by-year basis. The ongoing legislated threshold is $1,000, so if you have a genuine business purchase in mind, it may be worth bringing it forward.

4. Stay on Top of Your BAS and Lodgement Deadlines

Your Business Activity Statement is how you report and pay GST, PAYG withholding, and PAYG instalments to the ATO. Missing a BAS deadline can result in penalties and interest charges, and it is one of the most common compliance issues the ATO sees with small businesses.

Most small businesses lodge their BAS quarterly, with due dates roughly four weeks after the end of each quarter. If you lodge online, you generally get an extra two weeks.

The best way to avoid BAS stress is to keep your bookkeeping up to date throughout the year. If your bank accounts are reconciled and your expenses are coded correctly in your accounting software, preparing your BAS becomes straightforward rather than a last-minute rush.

If you use a registered BAS agent (like the team at Shoebox Books & Tax), they may also have access to extended lodgement deadlines, giving you a bit more breathing room.

5. Get Professional Help Before You Need It

Many small business owners only think about their tax when something goes wrong or when EOFY arrives. By then, it’s often too late to take advantage of strategies that could have saved money. Working with a bookkeeper and tax agent throughout the year means your records are always current, your BAS is lodged on time, and you can make informed decisions about things like asset purchases, super contributions, and structuring your tax affairs in the most tax-effective way.

It also means fewer surprises. If you know where your business sits financially at any point, you can plan for tax payments rather than being blindsided by a bill. A good tax agent can also help you manage your tax position across multiple income streams and make sure you’re meeting your super obligations.
