For many Australian business owners, the Business Activity Statement (BAS) is one of the most confusing and stressful parts of running a business. Late lodgements, missed GST credits, incorrect PAYG instalmentsโ€”the stakes are high when it comes to BAS. And the ATO isnโ€™t exactly known for leniency.

If you’ve ever asked yourself, “When should I hire a BAS accountant?” you’re not alone. In this article, we highlight 7 signs it’s time to seek BAS help before the ATO comes knocking.


๐Ÿšจ 1. Youโ€™ve Missed a BAS Lodgement Deadline (or Almost Did)

Keyword: missed BAS lodgement

ATO deadlines arenโ€™t flexible. Whether you lodge monthly or quarterly, missing a BAS lodgement can trigger immediate consequences:

  • Failure to Lodge (FTL) penalties
  • Interest charges on unpaid liabilities
  • Loss of GST credits or overpayments
  • Audit risk increases

Even one missed BAS lodgement can damage your compliance record.

โ€œThe ATO applied a $1,100 penalty because I was two weeks late on my March BASโ€”and I didnโ€™t even owe tax.โ€

A BAS accountant ensures every BAS is submitted correctly and on time. No stress. No late fees.


โ“ 2. Youโ€™re Not Sure What to Include in Your BAS Statement

Keyword: BAS help

The BAS isnโ€™t just about GST. Depending on your business structure and obligations, your BAS may need to include:

  • GST collected and GST credits claimed
  • PAYG withholding (for employee wages)
  • PAYG instalments (for your income tax)
  • Fuel tax credits
  • Fringe benefits tax instalments

If you’re unsure what applies to you, that’s a sign you need professional BAS help.

BAS mistakes lead to overpayments, missed deductions, or ATO BAS penalties.

A registered BAS accountant knows what your business should include and how to report it.


โฐ 3. Youโ€™re Spending Too Much Time on Bookkeeping

Running a business is time-consuming. The average small business owner spends up to 10 hours preparing their BAS each quarter.

If youโ€™re:

  • Spending your weekends reconciling accounts
  • Manually inputting figures into accounting software
  • Googling โ€œWhat goes into a BAS statement?โ€

… then it’s time to outsource this to a professional.

โœ… With a BAS accountant:

  • You reclaim hours each month
  • Your figures are accurate and reviewed
  • You lodge faster and with more confidence

Time is money. Let a qualified professional manage the complexity.


๐Ÿค” 4. Youโ€™re Unsure if Your GST Setup Is Correct

Many small businesses either forget to register for GST or register too early.

Common issues:

  • Charging GST when you’re not registered
  • Not charging GST when required
  • Claiming input tax credits incorrectly
  • Setting up software accounts wrong

Incorrect GST setup affects:

  • Pricing and invoices
  • Supplier payments
  • Eligibility for GST credits

A BAS accountant ensures your GST registration, reporting method, and setup are 100% correct.


๐Ÿ›๏ธ 5. Youโ€™ve Received ATO Notices, Penalties or Audit Warnings

Keyword: ATO BAS penalties

If youโ€™ve received an ATO warning letter, fine, or review notice, do not ignore it.

ATO notices can relate to:

  • Inconsistent BAS lodgements
  • Incorrect GST returns
  • Under- or over-reported PAYG
  • Suspicious account activity

Even a small mistake can snowball into an audit.

A BAS accountant can:

  • Review your past lodgements for accuracy
  • Communicate directly with the ATO on your behalf
  • Lodge amendments or overdue BAS statements

Professional BAS help now could prevent bigger problems later.


๐ŸŽ“ 6. You Have Employees or Contractors But Donโ€™t Understand Reporting Rules

Employing people introduces complexity.

You may need to report:

  • PAYG withholding (tax taken from employee wages)
  • Superannuation contributions
  • STP (Single Touch Payroll) reporting
  • Contractor ABN withholding (if they donโ€™t quote an ABN)

Mistakes in this area trigger ATO scrutiny and employee disputes.

A BAS agent helps:

  • Integrate payroll with your BAS process
  • Set up compliant employee reporting
  • Avoid double-reporting or underreporting PAYG

When it comes to staff, the cost of getting it wrong is far higher than the cost of expert help.


๐Ÿคฏ 7. You Donโ€™t Know if Youโ€™re Paying Too Much (or Too Little)

Perhaps the biggest reason to seek BAS help:

โ€œHow do I know Iโ€™m not paying too much GST or missing legitimate credits?โ€

An untrained eye can easily:

  • Underclaim GST credits
  • Double count income or expenses
  • Misclassify tax codes in software

Over time, this can cost thousands in:

  • Lost refunds
  • Overpayments to the ATO
  • Accrued penalties on underpayments

A BAS accountant reviews your figures to ensure you’re paying exactly what you oweโ€”no more, no less.


๐Ÿค What Does a BAS Accountant Actually Do?

You might wonder whatโ€™s included when you hire a BAS agent.

Services typically include:

  • GST and PAYG calculation
  • BAS statement preparation
  • Lodgement to the ATO
  • BAS amendments and corrections
  • ATO liaison on your behalf
  • Payroll integration and PAYG setup
  • Bookkeeping review and reconciliation

Some BAS accountants are also tax agents and can provide broader tax planning help.


๐Ÿ”ข The Cost of Not Getting BAS Help

Skipping professional help may seem like a way to save money, but the cost of mistakes quickly adds up:

Potential costs of going it alone:

  • FTL (Failure to Lodge) penalties: $275+ per BAS
  • Interest charges on underpayments: 10%+ annually
  • Audit costs and stress
  • Missed GST credits (hundreds or thousands per year)
  • Software subscriptions without professional use

Hiring a BAS accountant often pays for itself in avoided penalties and recovered credits.


๐Ÿ”Ž When to Hire a BAS Accountant: A Final Checklist

Wondering if itโ€™s the right time to bring in a professional? If any of the following apply, you need BAS help:

  • โŒ Youโ€™ve missed a BAS lodgement or barely met a deadline
  • โ“ Youโ€™re unsure what your BAS statement should include
  • โณ You spend more than 3 hours a month on bookkeeping
  • ๐Ÿค” Youโ€™ve received ATO letters, fines, or warnings
  • ๐Ÿ›๏ธ You have staff or contractors
  • ๐Ÿšซ Youโ€™re not confident your GST setup is correct
