Goods and Services Tax (GST) filing is a key responsibility for businesses in Singapore. It ensures that companies meet their tax obligations while maintaining compliance with local regulations. However, managing GST can be complex, and errors can lead to financial penalties and cash flow disruptions.

This article explores the good, the bad, and the taxing aspects of GST filing services, comparing in-house filing with professional assistance. We will also discuss common mistakes and best practices to help businesses stay compliant.
Understanding GST in Singapore
Singapore’s GST is a value-added tax levied on goods and services consumed within the country. As of 2024, the current GST rate is 9%, following the recent increase from 8% in January 2024. Businesses with an annual taxable turnover of more than SGD 1 million are required to register for GST to comply with the Inland Revenue Authority of Singapore (IRAS) requirements.
Once registered, companies must submit GST returns quarterly, adhering to strict GST submission deadlines. Failure to file on time may result in penalties, additional tax charges, or even legal repercussions.
Common GST Filing Mistakes
Handling GST filing without professional guidance can be challenging. Here are some of the most common mistakes businesses make:
Incorrect GST Calculations
Errors in tax computations, including over- or under-declaring GST, may result in discrepancies with IRAS records. These issues often arise when businesses apply the wrong GST rate or misstate input tax claims.
Missing GST Submission Deadlines
Companies are required to submit their GST returns within one month after the end of each accounting period. Late filing can incur fines starting from SGD 200, increasing over time if left unresolved.
Failure to Claim Input Tax Correctly
Many businesses overlook eligible input tax claims in Singapore, reducing the amount of tax credits they can claim. To qualify for input tax recovery, purchases must be supported by valid tax invoices and comply with IRAS guidelines.
DIY vs. Professional GST Filing Services
Should businesses manage their GST filing internally, or should they outsource it to experts? Let’s compare the two approaches:
In-House GST Filing (DIY Approach)
- Cost Savings – No need to pay for external services.
- Time-Consuming – Requires dedicated resources to track tax records.
- High Risk of Errors – Increased chances of miscalculations and late submissions.
- Lack of Expertise – Staff may not be fully familiar with IRAS regulations.
Professional GST Filing Services
- Regulatory Familiarity – Providers often work with current tax frameworks and filing requirements.
- Time Efficiency – Businesses can focus on core operations.
- Input Tax Support– Expert accountants can assist in identifying eligible input tax claims in Singapore.
- Automated Solutions – Many accounting and taxation services integrate software to simplify the filing process.
Given the complexity of GST regulations, outsourcing to professional GST filing services can significantly reduce risks and ensure compliance with IRAS.
How to Ensure Accurate GST Filing
Businesses can take several steps to improve the accuracy of their GST filings:
1. Stay Updated on Tax Regulations
Stay informed on updates from IRAS to avoid using outdated rates or missing new compliance requirements.
2. Implement Automation Tools
Accounting software can help track sales, expenses, and requirements for company GST registration in Singapore, reducing human errors in tax calculations.
3. Seek Professional Assistance
