Stamp duty on a Singapore tenancy agreement, explained

Stamp duty on a tenancy agreement in Singapore is calculated on the total rent payable over the lease term, not just the monthly figure. Rentie works this out for you automatically when you set up a lease, using the standard rate applied to the total rent across the tenancy period, so there is no separate form to fill in or spreadsheet to build.

This is general information, not tax advice — rules can change, and unusual lease structures (rent-free periods, step-up rents, very short or very long terms) can affect the calculation. If your tenancy is anything other than straightforward, it is worth checking the current rules on IRAS's website or with a tax adviser before you sign.

What Rentie removes is the manual part: once your lease terms are set, the duty is calculated, shown to both parties before signing, and kept on the tenancy record alongside the signed lease.
