What is the lease stamp duty formula?

Start with Average Annual Rent (AAR): monthly rent × 12. Check the exemption, then choose the formula by the length of the lease.

Lease term of 4 years or less

0.4% × total rent for the entire period of the lease

Lease term of more than 4 years or indefinite term

0.4% × 4 × AAR

AAR is based on the higher of contractual or market rent and can include maintenance, service and other consideration, excluding GST. An AAR not exceeding $1,000 is exempt.

Worked example: $3,000 monthly rent for 2 years

  1. 1. AAR: $3,000 × 12 = $36,000, so the exemption does not apply.
  2. 2. Term: 24 months is no more than 4 years, so use total rent.
  3. 3. Total rent: $3,000 × 24 = $72,000.
  4. 4. Duty: 0.4% × $72,000 = $288.

When must the tenancy agreement be stamped?

IRAS says a signed document should generally be stamped within 14 days after signing in Singapore, or within 30 days after it is received in Singapore if signed overseas. Check the agreement to see who is contractually responsible for the duty.

What else can be dutiable?

A lump-sum premium follows BSD rates, while rent can still attract lease duty. An increase in rent or an extension of the term can also create duty on the increase or extended period. Use IRAS for variations, premiums, market-rent questions and unusual consideration.
