What are the Singapore GST charges on the Horizons Invoice?

Starting March 1, 2025, Horizons Singapore became officially registered for Goods and Services Tax (GST). This means a 9% GST is now applied to all service fees invoiced through our Singapore-registered entity, in accordance with the Inland Revenue Authority of Singapore (IRAS) regulations.

You’ll first see this change reflected in your August 2025 invoice, which includes both ongoing GST and a one-time backdated charge for services billed from March through July 2025.

Horizons’ GST registration number is 202117926G, and we are required by IRAS to begin applying GST from the effective registration date.

What to Expect on Your Invoice

From August onward, your monthly Horizons invoice will include:

9% GST on all current service fees
A separate line item for the backdated GST covering March to July 2025

For example, if your monthly service fee was $1,500:

$1,500 × 5 months = $7,500 in total fees for March–July
$7,500 × 9% = $675 in backdated GST
This $675 will be added to your August invoice.

Then, your ongoing August GST would be $1,500 × 9% = $135.

Can You Recover the GST?

If your company is GST-registered in Singapore, you may be able to claim back the GST through your regular tax filings. If you’re not registered, recovery usually isn’t possible. In either case, we recommend speaking with your tax advisor or visiting iras.gov.sg for guidance.

What About Other Countries or Entities?

This change only affects clients billed through Horizons Singapore. If you’re billed through a Horizons entity in another country, or in a different currency, the GST charge does not apply.

Concerned About the Backdated Charge?

We understand that this may be unexpected. Unfortunately, the GST backdating is a legal requirement by IRAS — it reflects tax owed from the time Horizons became GST-registered. That said, if the one-time charge in August presents a challenge, let us know. We're happy to discuss flexible billing options on a case-by-case basis.

What About Discounts or Credits?

GST is applied to the net amount after any discounts, credits, or prepayments. If you have a custom billing arrangement, feel free to reach out and we’ll review it with you.
