Whether you’re late, filing nil, or unsure about your status, our team in Singapore is here to help you file accurately and on time.
We’ve likely answered it below.
A GST return is a statement submitted to IRAS that reports your business’s GST activity for a specific period. It includes the GST you collected from customers (output tax), the GST you paid on purchases (input tax), and your total sales and purchases. Accurate returns ensure you remain compliant and avoid audits or penalties.
If your business is GST-registered, whether by requirement or voluntarily, you must file GST returns either monthly or quarterly, based on your filing cycle assigned by IRAS. Filing is mandatory, even if your business had no transactions during the period. Late or missed filings may result in penalties.
Yes, you must file a GST return even if there were no sales or purchases during your assigned period (monthly or quarterly). This is called a nil return. Many businesses overlook this, but IRAS still requires it. Failure to file a nil return on time can result in late penalties.
IRAS imposes penalties starting from S$200 for each missed filing, increasing with continued delays. Repeated non-compliance can lead to audits or prosecution. Sleek helps prevent this by reviewing your filing cycle, preparing your return early, and submitting it before the due date, every time.
Your GST filing cycle is determined by IRAS at the time of registration. Most businesses are assigned a quarterly cycle, but some may be required to file monthly depending on the nature or volume of transactions. Sleek can help confirm your cycle and align your filing schedule to your accounting periods.
Yes, Sleek offers GST Return Filing as a standalone service. You don’t need to be on our full accounting plan to use it. If you already have an accountant or use another bookkeeping solution, we can still prepare, review, and submit your GST returns on your behalf.
You must begin filing from the effective date stated in your GST registration approval from IRAS. This could be as early as the following month or quarter. Sleek helps newly registered businesses track their filing start date and avoid first-time filing mistakes that could lead to penalties.
If your errors meet IRAS’s administrative concession thresholds (≤ S$3,000 net GST error and ≤ 5% of total supplies), you may adjust them in your next GST F5. Otherwise, file a GST F7. Sleek helps assess if your correction qualifies under IRAS’s Voluntary Disclosure Programme, which may reduce penalties for eligible GST F7 filings.
If you’re unsure about your filing obligations, for example, if you’re close to the S$1 million threshold or voluntarily registered, Sleek can help assess your status. We’ll guide you on whether filing applies, what your cycle is, and what steps to take next.
