When you do it online, it will save you time, minimise mistakes, and provide you with tranquillity. The age of loads of paperwork on your desk or struggling to recall popular tax regulations is gone.

This guide aims to answer multiple questions at once, providing a brief explanation of what BAS is in the accounting field, the specific preparation required for BAS, and the online lodgment process step-by-step. At the bottom of this blog, you will not only know how you could lodge BAS online, but also the most anticipated mistakes that could be made, and be a better judge of deadlines without sacrificing your financials.

What is BAS, and Who Needs to Lodge It?

A Business Activity Statement, also known as BAS, is a tax statement about your business. It reminds the ATO of the amount of GST you have collected, the mandated amounts of PAYG to be paid, and any other liabilities that are due for your business. In simple terms, it is as straightforward as a financial health check-up, and it takes care of your tax affairs, ensuring your company remains compliant with tax regulations.

Who must lodge BAS? In any of these accounts, it is required that BAS lodgment be done:

  • GST-registered businesses

  • Single traders and self-employed contractors.

  • With employees in a small business.

  • Businesses that are bound to report PAYG withholding.

BAS is a function intended to represent a fiscal overview of your business over a specific duration. Regular BAS lodgement is essential, even for a small business just getting started. Failing to secure lodging at the right time or in the correct place can result in penalties, interest, and unwarranted worries.

Methods to Lodge BAS in Australia

Australia has several approaches regarding lodging BAS. The right one to choose will depend on how comfortable you are, the tools you use, and whether you prefer to do it yourself or have professional assistance.

1. Lodging Online through the ATO Business Portal

This is the most straightforward alternative for most small business owners. The ATO portal will enable you to log in, prepare your BAS and submit it in real time. It is quick, with no paperwork, and you can access earlier statements at any time.

2. Lodging through myGov

There are also jurisdictional owners of small businesses making applications through myGov. This will be convenient, but it is limited, as you will have to connect your business account and update all financial information. It suits freelancers or micro-businesses that manage their taxes digitally.

3. Lodging with Accounting Software

Applications such as Xero, QuickBooks, and MYOB can be connected with the ATO to have the data filled in advance. With a few clicks, you can build BAS reports, thus minimising the errors in manual reporting. This is particularly convenient if you already keep track of your costs in numerical format. 

5. Lodging with a Registered BAS Agent

Unless taxes are your special major, or you have the time to spare, both can be done by a registered BAS agent filing on your behalf. They verify all details, submit them on time, and even take the initiative to address complex GST or PAYG inquiries.

Compare all strategies based on speed, accuracy, and your level of comfort working with numbers. Mistakes that are expensive due to human factors can be avoided through automation and expert assistance.

Step-by-Step Guide: How to Lodge BAS Online via ATO Portal

By submitting your BAS online through the ATO portal, you can stay in line with one of the quickest and most reliable methods. When you make a digital filing, you will save yourself time, minimise errors, and your tax liability in your business will be clearly recorded. The step-by-step guide below provides a clear and easy-to-follow process for lodging BAS online.

Step 1 – Log in to the ATO Business Portal

The authority to use the ATO Business Portal first requires entering the ATO Business Portal to your myGov account associated with your business or an AUSkey. Ensure that you update your ABN and business details to avoid using incorrect information in the submission. This is your first visit; please take a moment to explore the portal dashboard. Items that are provided in the menus and forms will make the process of submitting your BAS easier.

Step 2 – Gather All Required BAS Information

Prepare all the financial information for the reporting period and complete your BAS before submission. This includes:

  • GST collected and GST credits.

  • Withholding from employees' PAYG.

  • Instalments of PAYG and whatever other taxes you pay regarding your business.

This can be simplified with the help of accounting software such as Xero, QuickBooks, or MYOB. To avoid errors, basic preparation is essential. To discuss, with an amount of GST collected of $5,000 and Credits due of $1,200, your net GST due is $3,800. Confirm at least rigorously that you have arrived at the correct calculations before proceeding to the next step.

Step 3 - Fill Out the BAS Form

Once you have your information prepared, it's time to ensure you enter the numbers in the relevant fields on the ATO portal. Common areas include GST, PAYG withholding, PAYG instalments, and any other applicable tax, as available.

Guidelines on the Correct Completion of BAS Form:

  • Provide precise figures as you record them in your accounts; do not round off the numbers.

  • Use an example of the past BAS form to compare with.

  • Verify that there are no missing or misplaced entries, particularly in GST and PAYG.

Step 4 - Review & Confirm Entries

Review carefully all totals and entries before submitting. Even simple mistakes can result in penalties or ensuing investigations by the ATO. Suggested pitfalls include having negative figures where there should be none, and false GST figures, or omission of PAYG figures. It is advisable to be cautious of first-time lodgers, as one can have a colleague or a registered BAS agent review the form.

Step 5 - Submit and Save Confirmation

As soon as you register that everything is correct, you will be asked to submit. The portal will produce a confirmation receipt- always save a copy in digital format or print a copy. This acceptance is crucial evidence of acceptance in the audits or disagreements. Most business owners save the confirmations in cloud folders, where they are easily accessible along with invoices and employee payrolls.

Large-scale Automation tools and cloud accounting make the BAS process significantly easier, error-free, and save a significant amount of valuable time. Correct base preparation not only does not represent compliance but also serves as one of the steps of wiser financial means management.

Common Mistakes to Avoid When Lodging BAS

Although it is handy to find an online method of lodgment, errors might occur. The first step towards its prevention is awareness. The following is how the most common BAS errors can be prevented:

  1. Late Submission: Late companionship of BAS will lead to a fine and interest. Set up calendar notifications or accounting software alerts to stay on schedule.

  2. Incorrect GST Reporting: Exaggerating or underestimating GST would lead to significant problems with the ATO. Always match GST collected and GST credits using invoices.

  3. PAYG Withholding Errors: More fines may be incurred when employee PAYG calculations are made incorrectly. Verify payroll to ensure that proper amounts are reported.

  4. Not Saving Confirmation Receipts: As with the online submission of BAS, a confirmation receipt is provided. Any failure to do this would present difficulties in situations where the ATO demands evidence of lodgment.

  5. Using Outdated Records: Use of old/completed financial records is likely to cause errors. Always keep all records up to date, preferably in a cloud-based accounting format.

It is by not committing such errors that you will file your BAS online in good standing, stay updated and clear up on avoidable forms of stress or fines.

Deadlines & Penalties for BAS Lodgment

Whether you submit quarterly or monthly, being aware of key dates and potential penalties can help your business stay compliant. Proper base preparation will translate to smooth trends in submissions and minimised errors.

Quarterly vs Monthly Lodgers

Depending on the turnover and GST payable, Australian businesses make quarterly or monthly returns of the BAS.

  • Quarterly Lodgers: The majority of the small business corporations are found here. BAS is returned quarterly, summarising GST, PAYG, and other relevant details.

  • Monthly Lodgers: Lodging monthly may be beneficial for larger businesses with high employee turnover. Depositing monthly ensures that their transactions are recorded with utmost regularity.

Penalties, cash flow plan, and deadlines depend on the frequency of lodgment.
