If you are incorporating a new company in Singapore and plan to register for GST voluntarily from 1 April 2026 onwards, InvoiceNow is a condition of your registration. It applies from the effective date of your GST registration, not a future phase you can plan for later.
This means you need a Peppol ID and an InvoiceNow-Ready Solution set up before you issue your first invoice.
Who this applies to
New voluntary GST registrants from 1 Apr 2026: InvoiceNow applies from your GST effective date.
New compulsory GST registrants: covered from 1 April 2028.
Not GST-registered: the requirement does not apply, but you can adopt InvoiceNow voluntarily.

What to set up before Day 1
If you are registering for GST voluntarily from 1 April 2026, treat InvoiceNow readiness as part of your company setup — alongside incorporation, bank account opening, and Corppass activation.
- 1Choose an InvoiceNow-Ready Solution. From your date, you submit invoice data to IRAS through it, sent via an accredited Access Point. See how to choose an InvoiceNow-Ready Solution.
- 2Register for a Peppol ID. Your provider registers your Peppol ID using your UEN. See the Peppol ID registration guide.
- 3Set up your chart of accounts and GST codes. Set up your GST tax codes (such as SR, ZR and ES33) and your chart of accounts before you issue your first invoice.
- 4Send a test e-invoice. Before your GST effective date, send a test invoice through the Peppol network to confirm your setup works end-to-end.
The advantage of starting on InvoiceNow
Established businesses need to migrate existing workflows, retrain staff, and reconcile old processes. A new company has none of that baggage. If you start with an InvoiceNow-Ready Solution from day 1, you skip the migration entirely:
- •Every invoice you issue goes through InvoiceNow from the start — no backlog to catch up on
- •Your staff learn one workflow, not two
What if I'm not registering for GST yet?
If your company's taxable turnover is below the S$1 million threshold and you are not voluntarily registering for GST, the InvoiceNow requirement does not apply. You can still get a Peppol ID and start receiving e-invoices from suppliers.
If your revenue is approaching the threshold, plan ahead: new compulsory GST registrants are covered from 1 April 2028.
Where MassAdmin fits
MassAdmin is not an IMDA-accredited InvoiceNow-Ready Solution. On Business and above it exports invoices as Peppol-format (PINT SG) files; sending them through an accredited Access Point is planned. IRAS lists free InvoiceNow-Ready packages, aimed at small businesses with few invoices, until 31 March 2031; if e-invoicing is all you need, one may fit. MassAdmin is for the rest of the back office: payroll with CPF, your books and e-signatures, in one login.
You use an InvoiceNow-Ready Solution to submit invoice data to IRAS from your date.

Questions
Do new companies in Singapore need InvoiceNow?
If your new company registers for GST voluntarily on or after 1 April 2026, InvoiceNow is a condition of your registration and applies from its effective date. New compulsory registrants are covered from 1 April 2028. If you are not GST-registered, the requirement does not apply to you.
When should a new company set up InvoiceNow?
Before you issue your first invoice. If your GST registration is effective from day 1, you need an InvoiceNow-Ready Solution working on that date. Ask your provider how long registration and testing take, and allow for it.
Can I start using InvoiceNow before GST registration?
Yes. A Singapore business can get a Peppol ID and receive e-invoices through InvoiceNow without being GST-registered. Submitting invoice data to IRAS is required only once the GST InvoiceNow Requirement applies to you.
