Rental (Lease) Stamp Duty Formula Explained, With Examples

Updated 5 Oct 2026 in Tax & GST

Every rental (lease) stamp duty result comes from one formula. Once you understand what goes into it, you can sanity-check any figure you are given, whether by an employer, a bank, a teacher or another website.

The formula

Stamp duty = 0.4% × total rent for the lease period. Leases with total rent of S$1,000 or less are remitted.

Why it matters

Singapore's tax system is simple by global standards, but the progressive bands, reliefs and the 9% GST still trip people up. A quick calculation helps you set aside the right amount before IRAS sends your notice of assessment, or check that a bill has been worked out correctly.

The Goods and Services Tax rose from 8% to 9% on 1 January 2024. Businesses with taxable turnover above S$1 million must register, and GST-registered retailers must quote prices to consumers inclusive of GST, so most shelf prices already include it.

Singapore taxes individuals on income earned in Singapore, with progressive rates for residents that start at 0% on the first S$20,000 of chargeable income and rise to 24% on income above S$1 million. Tax is assessed a year in arrears: income earned in 2025 is assessed in Year of Assessment 2026.

Tax planning in Singapore is mostly about timing and reliefs rather than complex structures. Topping up CPF, contributing to SRS and claiming every relief you qualify for can lower your marginal rate band, and the savings are larger for higher earners.
