GST is the one area where penalties don’t come alone — they stack. Late registration, late filing, late payment: miss one and the damage amplifies, quarter after quarter. We register you correctly, file on time, and keep you ahead of the rules.
Miss it and the damage compounds. Get it right and it’s simple.
GST isn’t a one-time form. It’s an ongoing obligation with penalties that build on each other — and a digital shift coming that catches the unprepared. Here’s what actually matters.
Late registration, late filing and late payment are three separate penalties — and they stack. Miss the start and IRAS backdates you; miss the quarters and each one piles on the last. The longer it’s left, the bigger it grows. We keep you on time, every time.
GST-registered businesses must keep every record for at least 5 years — invoices, receipts, import permits — and IRAS can ask for any of it in an audit. Paper in a drawer is asking for trouble. Proper software like Xero or QuickBooks keeps it timestamped, traceable, retrievable — and gets you InvoiceNow-ready. If a claim is ever questioned, the evidence is right there.
Output tax is the GST you charge; input tax is the GST you pay on purchases and imports — and what you can claim back. Get the classification wrong and you either over-pay or claim something you shouldn’t. An experienced hand on your books makes sure you claim every dollar you’re entitled to — and nothing you’re not.
InvoiceNow is making e-invoicing to IRAS mandatory, phasing in over the next few years. Still invoicing the old way? Your date may be sooner than you think. We track the changes that affect you and move you across before the deadline. Your business, our business.
Most people think a missed GST obligation means one penalty. It rarely does. The three penalties layer on top of each other — and the clock keeps running.
Cross the threshold and register late, and IRAS backdates your registration to when you should have registered — you owe the GST you never collected from your customers.
Every GST return is quarterly. Miss a filing and a penalty applies — and it keeps building each quarter you’re late, stacking on what came before.
On top of filing, the tax owed attracts a late-payment penalty that grows the longer it sits unpaid. Three clocks, all running at once.
IRAS is phasing in InvoiceNow — sending your invoice data digitally via the national e-invoicing network. It’s already live for new voluntary registrants, and rolls out to everyone else by size. Here’s the schedule.
IRAS will notify businesses registered before 2026 of their exact implementation date by mid-2026, and government funding is available to help SMEs onboard. The safe move is to get on InvoiceNow-ready software early — not scramble at the deadline.
GST from registration to filing — assessed for your business, not just your turnover.
We assess whether you must register, or whether voluntary registration benefits you — then handle the application end to end.
We watch your taxable turnover and flag the S$1M threshold before you cross it — no nasty backdated surprises.
Your F5 returns prepared and filed on time, every quarter — input and output tax classified correctly.
We get you onto InvoiceNow-ready software ahead of your mandatory date, so the digital shift is a non-event.
Proper 5-year record-keeping in cloud software — timestamped, traceable and ready if IRAS ever asks.
A direct WhatsApp line for GST questions, plus updates whenever the rules change. Compliance, the modern way.
Registration is compulsory once your taxable turnover exceeds S$1M, or you reasonably expect it to in the next 12 months. Miss the window and IRAS can backdate your registration — you’d owe GST you never collected. Below $1M, voluntary registration is possible and can be worthwhile if you carry significant input GST.
It depends on your business. If you import goods or carry heavy GST on purchases, registering lets you claim that input tax back instead of absorbing it as a cost. But voluntary registration comes with obligations — you generally must stay registered at least two years and file quarterly. We assess whether it’s a net win for you before you commit.
InvoiceNow is Singapore’s national e-invoicing network. IRAS is making it mandatory for GST-registered businesses to transmit invoice data digitally — already required for new voluntary registrants from April 2026, and phasing in for everyone else between 2028 and 2031 by business size. If you’re still invoicing manually, you’ll need to move to InvoiceNow-ready software. We handle that move for you.
Output tax is the GST you charge your customers. Input tax is the GST you pay on your own purchases and imports, which you can generally claim back once registered — provided it’s properly documented and business-related. Correct classification is where an experienced accountant earns their keep.
At least 5 years — invoices, receipts, import permits and accounting records — even if your business has stopped or deregistered. Keeping it all in cloud software means it’s organised, timestamped and instantly retrievable if IRAS ever conducts an audit.
You can face penalties on three fronts — late registration (backdated), late filing (which builds each quarter), and late payment on the tax owed. Because they stack, a small slip can grow into a significant bill. That’s exactly why we track your obligations and file ahead of every deadline.
