3 Costly Singapore Business Compliance Mistakes to Avoid

Think your business is compliant? You might be surprised..

Many business owners are so focused on growing sales, serving customers, and managing daily operations that compliance takes a back seat.

Unfortunately, that's where costly mistakes happen.

At Account-Ink, we've helped many Singapore business owners fix compliance issues that could have been easily prevented. Some resulted in penalties, others delayed funding, bank applications, or even caused unnecessary stress during tax season.

Here are three of the most common mistakes we see—and how you can avoid them.

1. Forgetting to Register for GST After Revenue Exceeds S$1 Million

This is one of the biggest compliance mistakes made by growing businesses.

Many business owners assume they only need to register for GST after receiving S$1 million in cash. Others simply don't realise that the threshold is based on taxable turnover.

When is GST registration compulsory?

You generally need to register for GST if:

• Your taxable turnover exceeded S$1 million in the past 12 months, or

• You expect your taxable turnover to exceed S$1 million in the next 12 months.

Waiting too long to register can lead to:

• Late GST registration penalties

• Backdated GST payments

• Interest charges

• Administrative penalties from IRAS

Real-life example

Imagine your business grows rapidly after securing several corporate clients.

Your annual revenue reaches S$1.15 million, but because you're busy fulfilling orders, nobody notices the GST threshold has been crossed.

Six months later, you realised you need to register for GST.

You may be required to account for GST on past sales—even if you never collected GST from your customers.

That means the GST comes directly out of your profit.

What you should do

Review your revenue every month instead of waiting until year-end.

If you're unsure whether your business needs to register, speak to a professional before IRAS contacts you.

2. Moving Office but Forgetting to Update Your Registered Address with ACRA

"We've already updated our website and Google Business Profile."

Great.

But did you remember to update ACRA?

Every Singapore company must maintain a valid registered office address with ACRA.

This is where official government correspondence is sent, including notices from:

• ACRA

• IRAS

• Ministry of Manpower (MOM)

• Courts and government agencies

  
  

Why this matters

Many businesses move into:

• Home offices

• Co-working spaces

• New commercial offices

• Retail outlets

  
  

Yet they forget to update ACRA.

If important notices are sent to your old address, you may never receive them.

This could lead to:

• Missed filing deadlines

• Penalties

• Compliance breaches

• Missed legal correspondence

  
  

Updating your registered address takes only a short time but can prevent significant problems later.

3. Assuming "No Business Activity" Means No Need to File Annual Return

This is probably the most common misconception among first-time business owners.

"My company does not have any business activities this year."

"So I don't need to do anything."

Unfortunately, that's incorrect.

As long as your company remains incorporated in Singapore, it still has ongoing statutory obligations.

These may include:

• Annual Return filing with ACRA

• Financial statements (where applicable)

• Corporate tax filing with IRAS

• Maintaining statutory registers

• Keeping company records up to date

  
  

Even dormant companies usually have filing obligations.

Failure to file can result in:

• Late filing penalties

• Composition fines

• Directors being prosecuted for repeated non-compliance

• Difficulties closing or selling the company later

  
  

If you no longer intend to use the company, consider applying for a proper strike-off instead of simply ignoring it.

Why These Mistakes Happen

Most business owners don't intentionally ignore compliance.

They're simply busy.

Their focus is on:

• Winning customers

• Managing cash flow

• Hiring staff

• Delivering products and services

  
  

Compliance deadlines often stay invisible until a penalty arrives.

That's why having a trusted corporate secretary isn't just about filing paperwork.

It's about ensuring someone is proactively keeping your business compliant while you focus on growth.

A Simple Compliance Checklist Every Singapore Business Owner Should Review

✅ Has my annual revenue exceeded or is it likely to exceed S$1 million?
