How to Calculate Stamp Duty for a Residential Tenancy Agreement

Stamp duty on a residential tenancy agreement is a tax imposed on the document that creates the lease, not the rent itself. The rate is 0.4% of the total rent payable over the lease period, calculated after rounding down the total rent to the nearest dollar. All tenancy agreements in Singapore must be stamped to be admissible as evidence in court, and e-stamping has been mandatory since 2013.

The Basic Formula

Duty = 0.4% × total rent (capped at 4 years’ rent)

For leases of any duration, compute the total rent by multiplying monthly rent by the number of months. If the lease period exceeds 4 years, IRAS caps the rent at 4 years. The total rent is always rounded down to the nearest dollar before applying the rate.

No duty is payable if the computed amount is below $1.

Worked Example

A 2‑year lease with a monthly rent of $3,200:

• Total rent = $3,200 × 24 = $76,800 (already a whole dollar, no rounding needed)
• Duty = 0.4% × $76,800 = $307.20

Pay $307 (IRAS rounds down the duty to the nearest dollar for payment).

If the monthly rent were $3,250, the total rent would be $78,000 exactly. Duty = $312.

4-Year Cap Rule

For a lease of 5 years at $4,000 per month:

• Unrestricted total rent = $4,000 × 60 = $240,000
• Capped at 4 years = $4,000 × 48 = $192,000
• Duty = 0.4% × $192,000 = $768

This cap prevents excessive duty on long-term leases. Even if you sign a 7‑year lease, you pay based on 4 years’ rent.

Rent-Free Period and Variable Rent

A rent‑free period does not reduce the total rent for stamp duty calculation. You must include the rent that would have been payable during that period if the lease states a waiver. For variable rent (e.g., stepping up after year one), use the total rent actually payable across the fixed term. If the rent is not yet determinable (like a turnover lease), you must stamp based on an estimate and later stamp a supplemental agreement if the rent exceeds the estimate by more than 25%.

Step‑by‑Step E‑Stamping on IRAS Portal

1. Log in to the IRAS e-Stamping portal with your Singpass.
2. Select “Request a New Stamp” → “Tenancy Agreement / Lease / Licence.”
3. Fill in details: property address, lease start/end dates, monthly rent, parties.
4. The system automatically computes the total rent and the duty payable.
5. Pay by NETS, credit card, or PayNow. You will receive a stamp certificate immediately.

Stamping must be done within 14 days of signing if the agreement is signed in Singapore, or within 30 days if signed overseas. Late stamping attracts a penalty of up to 4 times the duty, subject to a minimum of $10.

Why Stamp Duty Matters

An unstamped agreement cannot be used as evidence in a dispute. The Inland Revenue Authority of Singapore (IRAS) can impose penalties on both the landlord and tenant as they are jointly liable. Since 2020, digital stamp certificates are accepted by banks, schools, and authorities for proof of residence, making timely stamping a routine but critical step.
