5 Most Costly Tax Mistakes For Ipswich Businesses: Avoid These In 2026

The 2026 tax season is just around the corner, and if you’re like most Ipswich business owners or individuals, you want to get things right the first time.

But every year, people make the same errors - errors that cost them big in penalties, missed deductions, and lost time.

In this guide, we’re covering Ipswich’s 5 Most Costly Tax Mistakes To Avoid In 2026, whether you lodge your return solo or work with an accountant, understanding these traps can save you thousands and keep the ATO off your back.

Let’s take a closer look at what to avoid - and what to do instead.

1. Not Keeping Accurate and Up-To-Date Records

Poor record-keeping is hands down one of the most common tax mistakes we see  Ipswich businesses make. If your receipts are crumpled in the glove box or your invoices are missing, you're setting yourself up for trouble.

The ATO requires you to keep:

• Receipts for work-related and business expenses
• Bank and loan statements
• Records of income from all sources
• Super and PAYG summaries

Failing to keep accurate records means you risk missing deductions or being hit with penalties during an audit. At Skyways Accountants Ipswich, we recommend using digital tools to make this process easier. When you’re organised, your accountant can work faster - and find more opportunities to save.

2. Claiming Deductions You're Not Entitled To

Sure, everyone wants to reduce their tax bill—but claiming deductions that don’t hold up under scrutiny is a fast way to land in hot water.

Like 2025, in 2026, the ATO will continue to focus on:

• Overstated work-from-home expenses
• Unsubstantiated car and travel claims
• Incorrect use of asset write-offs
• Double-dipping on deductions (like claiming the same cost twice)

If you're unsure whether something qualifies, speak with a local Ipswich accountant before submitting. One of the Ipswich’s 5 Most Costly Tax Mistakes To Avoid In 2026 is assuming you can “just claim it” without proof. Getting it wrong can trigger audits, penalties, and amended assessments.

3. Missing Tax Deadlines and Lodgement Dates

Late lodgements don't just cause stress—they can cost you money in penalties and interest charges.

Important 2026 dates to remember include:

• 30 June 2026 – End of financial year
• 31 October 2026 – Deadline for individuals lodging their own returns
• Later dates may apply if you're using a registered tax agent

If you’re running a business, don’t forget BAS and PAYG due dates throughout the year. Missing these can hurt your cash flow and damage your compliance record with the ATO. This is a major reason why many locals choose to work with a tax agent - we handle the deadlines so you don’t have to.

4. Ignoring Superannuation Obligations

If you're an employer in Ipswich, super is not optional. Failing to pay the correct amount - or missing the quarterly deadlines, can lead to super guarantee charges, admin fees, and interest. Even self-employed individuals often overlook the benefits of voluntary contributions. These can reduce your taxable income and grow your retirement savings at the same time.

In 2026, the superannuation guarantee rate is expected to remain at 11%. Stay updated with any changes, and make sure all payments are processed through SuperStream-compliant systems. One of Ipswich’s 5 Most Costly Tax Mistakes To Avoid In 2026 is ignoring your super responsibilities - because the ATO isn’t ignoring them.

5. Not Getting Professional Advice When You Need It

It’s tempting to do your taxes yourself, especially with software tools becoming more user-friendly. But tax laws are constantly changing. What worked last year might not apply in 2026. A wrong step could wipe out your refund or trigger an audit.

Here’s what a local Ipswich accountant can do for you:

• Review your financials and identify legal tax-saving opportunities
• Ensure you're meeting ATO compliance standards
• Lodge on time and avoid late penalties
• Support you during audits or disputes

Too many people wait until there’s a problem to seek help. Getting professional advice early is smarter - and far less stressful.
