IRAS e Stamping Portal: Step by Step Guide

Tax & policy · Stamp duty

Quick answer: Every tenancy agreement and every property transfer document in Singapore needs to be stamped through IRAS's e Stamping portal, and the process is entirely online: log in with Singpass or CorpPass, select the document type, enter the party and property details, let the portal compute the duty, pay, and download your stamp certificate. For a simple tenancy agreement this can take minutes end to end. For a property transfer, more fields and sometimes more verification are involved, so build in more time. The mistakes that cause delays are almost always the same: wrong document dates, incomplete party details, and leaving it until after the deadline has passed.

Rates and thresholds change. The current figures are kept in one place: the Singapore property rules reference.

I walk clients through the e Stamping portal often enough that I can predict where they will pause. It is not a complicated system, but it asks for information in a specific order and it is unforgiving of small mistakes in dates or names. This is a practical walkthrough of the two situations you will most likely encounter, stamping a tenancy agreement and stamping a property transfer, with the fields the portal actually asks for and where people tend to trip up.

What e Stamping is and why it is not optional

Stamp duty in Singapore is not something you calculate and simply pay into a general account. Every dutiable document, a tenancy agreement, a sale and purchase agreement, a transfer instrument, has to be formally stamped, and the e Stamping portal is how that happens for the vast majority of transactions today. Stamping does two things at once: it evidences that the correct duty has been paid, and it produces a certificate that is generally required for the document to be relied upon later, including in court if a dispute ever arises. An unstamped tenancy agreement is a real risk precisely because of that second point, not just the financial penalty for stamping late.

Before you start: what to have on hand

Have the signed document and its key details ready before you open the portal, since the fields ask for information drawn directly from what was agreed, not estimates.

Your Singpass or CorpPass login. Individuals use Singpass, businesses and entities use CorpPass or the relevant business login.
The exact date the document was signed. This determines your stamping deadline and whether any late penalty applies.
Full names and identification details of all parties. Landlord and tenant, or buyer and seller, exactly as they appear on the document.
The property address and details. Block, unit, postal code, and property type.
The financial terms. Monthly rent and lease term for a tenancy, or purchase price for a transfer.
A payment method. The portal accepts common online payment options for settling the duty once calculated.

Walkthrough: stamping a tenancy agreement

Log in to the e Stamping portal with Singpass. Select the option for stamping a tenancy agreement or lease.
Enter the landlord and tenant details. Full names and identification numbers for each party, matching the signed agreement exactly.
Enter the property details. The address of the rented unit, and confirm the property type where prompted.
Enter the lease terms. The monthly rent, the lease start and end dates, and any option to renew period if stated in the agreement.
Review the computed duty. The portal calculates the stamp duty payable based on the rent and lease term you entered. Check this against your own expectation before proceeding.
Pay and download the certificate. Once payment is confirmed, the stamp certificate is generated and available to download, which you should save and keep with your copy of the signed agreement.

For a straightforward residential lease with no unusual clauses, this whole sequence is genuinely quick, often completed within a single sitting once you have your details ready.

Walkthrough: stamping a property transfer

The fields differ from a tenancy stamp

A property transfer, whether a purchase, a sale, or an inter spouse transfer as part of a restructuring, asks for a different set of fields centred on the transaction value and the parties acquiring or disposing of the interest. Expect to provide the purchase price or the consideration for the transfer, the property's identifying details, the parties' full particulars, and depending on the nature of the transfer, additional context such as whether Additional Buyer's Stamp Duty applies based on the acquiring party's profile. Because more is at stake financially and legally, take extra care that every figure entered matches the executed document exactly, since a mismatch can require correction after the fact, which is more friction than getting it right the first time.

For a property transfer, it is also worth having your conveyancing lawyer involved, or at least aware, before you submit, since they are often the ones handling the e Stamping as part of completion in any case. If you are doing it yourself, treat the purchase price and any ABSD related declarations as the fields to triple check before you pay.

Typical processing time

For most tenancy agreements with straightforward terms, the certificate is generated shortly after payment, often within the same session, because the calculation is formulaic and does not usually require manual review. Property transfers can take longer where IRAS needs to verify additional details, such as valuation questions or more complex ownership structures. Processing times are set and updated by IRAS, so check the current expected turnaround on the portal itself at the time you submit, rather than relying on a fixed number from memory, since this is exactly the kind of operational detail that changes.

Common mistakes that cause delays

Entering the wrong signing date. This affects your stamping deadline calculation and any late penalty assessment, and it is the single most common data entry error.
Mismatched party names. Names entered on the portal that do not exactly match the signed document can require correction before the certificate is treated as valid.
Leaving it until the deadline has passed. Documents are expected to be stamped within a set window after signing, and waiting until the last moment leaves no room for correcting an error before a penalty applies.
Guessing at the property type or details. Selecting the wrong property classification can affect the duty calculation, so confirm the correct classification rather than assuming.

None of these mistakes are difficult to avoid. They come from rushing, which is exactly what happens when stamping gets left to the last day rather than done promptly after signing.

Frequently asked questions

Do I need Singpass to e Stamp a document with IRAS?

Yes, individuals log into the e Stamping portal using Singpass, and businesses or entities typically use CorpPass or the relevant business login credentials. You cannot complete an e Stamping submission anonymously, since the portal ties the stamp certificate to the identity of the person or entity submitting it, which also helps confirm who is responsible for paying the duty.

How long does e Stamping take once I submit the details?

For most straightforward documents, such as a standard tenancy agreement with no unusual terms, the certificate is typically issued shortly after payment is made, often within the same session. More complex submissions, particularly property transfers where IRAS needs to verify valuation or additional details, can take longer to process. Always check the current expected processing time on the portal itself rather than assuming a fixed number of days, since this can change.

What happens if I stamp a tenancy agreement late?

Documents in Singapore are expected to be stamped within a set window after signing, and stamping late attracts a penalty on top of the duty itself. Beyond the financial penalty, an unstamped or improperly stamped document generally cannot be relied on as evidence in court if a dispute arises, which is the real risk landlords and tenants underestimate. Stamp promptly after signing rather than treating it as an administrative task to get around to later.

Can I e Stamp a document on behalf of someone else?

Yes, a person can submit an e Stamping application on behalf of another party, such as an agent assisting a landlord or a law firm acting for a buyer, provided they have the necessary authorisation and the correct party details are entered accurately in the submission. The stamp certificate itself reflects the parties to the underlying document, not necessarily the person who physically completed the online submission, so accuracy in the party fields matters more than who is logged in.
