Did you know that thousands of businesses in Australia make silly mistakes when lodging their bills of sale every quarter? This not only costs them money but can also put your business at legal risk. A Business Activity Statement or BAS is a report that business owners must lodge with the Australian Taxation Office (ATO) to state their Goods and Services Tax (GST), Pay As You Go (PAYG) instalments and other tax payments.
Although lodging a BAS is a straightforward process, many businesses make mistakes, such as incorrect GST, inaccurate employee income reporting, double counting of purchases, etc. These could cause compliance issues, affecting your overall business growth. Fortunately, ATO has created processes to help you fix BAS mistakes without penalties. Make sure you act as quickly as possible to save time, money and unwanted stress.
Here is a comprehensive guide to help you understand common BAS mistakes and the process to fix them without stressing the ATO. It is always good to consult Melbourne bookkeepers to prevent future errors and penalties.
Let’s Get Started!
Despite new age accounting software and automation, BAS lodgement errors are still on the rise. Whether you have a small retail store or a giant venture, a basic slip up can affect your GST, PAYG or cash flow. These reflect the most recurring blunders that businesses consistently commit. These are:
The ATO knows the fact that most businesses make silly BAS blunders. Therefore, they treat honest errors differently from non compliance. If you spot a BAS mistake and disclose it promptly, you could prevent potential penalties.
Penalties are often imposed when a business repeatedly commits errors. In such a scenario, lodging a correction as soon as you notice the blunder can save you money and serious repercussions. That’s why hiring experienced Melbourne bookkeepers makes a world of difference.
Make sure you act as quickly as possible to avoid ATO penalties:
Carefully review your BAS to spot discrepancies, such as incorrect GST reporting. You’ll need to check receipts, invoices, payroll entries and other BAS components to find potential errors.
In this step, you’ll need to determine whether the mistake affects PAYG, GST and other elements of BAS. Understanding the type of blunder can help you make corrections easily.
If your BAS report has minor blunders, they can be corrected in your next lodgement. However, critical ones require a formal BAS revision in Australia.
You can directly submit corrections through the ATO portal. You can even ask your bookkeeper in Melbourne to handle the process.
Completing the BAS amendment form or lodging a revised BAS ensures the ATO has the correct records. Ensure you add the revised amounts along with relevant notes.
An adjustment occurs when something changes after you lodge your BAS. This could be due to:
In these scenarios, adjustments are reported in your next BAS.
First things first, use accounting software as it will automatically calculate GST and PAYG amounts, reducing human errors. Make sure you regularly reconcile your bank statements and update your books frequently. Moreover, staying updated with ATO rules, such as changes in tax legislation, etc can help prevent future errors.
If you don’t want to make silly mistakes, book trained bookkeepers in Melbourne and solve complex transactions while meeting your ATO bookkeeping requirements. They keep a close eye on cash flow, GST and PAYG reports to prevent financial blunders.
Fixing BAS mistakes isn’t a complex task. The key is to act promptly and make changes accordingly. The sooner you resolve the issue, the easier it is prevent ATO penalties and other costly fines.
