Tenants must pay stamp duty (a tax on tenancy agreements) within 14 days of signing the contract in Singapore.
When signing a document electronically, it counts as being signed in Singapore if:
A person in Singapore retrieves or accesses the electronic document
A person stores the electronic document on a device (e.g., a computer) and brings it to Singapore
A person stores the electronic document on a computer in Singapore
If you sign the agreement outside of Singapore, you have 30 days after receiving the document to pay the tax.
Visit the Inland Revenue Authority of Singapore (IRAS) website for more information on how to calculate and pay stamp duty online or in person at a service bureau.
