The formulas
Lease ≤ 4 years → Duty = 0.4% × total rent payable over lease Lease > 4 years → Duty = 0.4% × Average Annual Rent (AAR) × 4
Worked examples
| Monthly rent | Lease term | Total rent | Stamp duty |
|---|---|---|---|
| $2,500 | 12 months | $30,000 | $120 |
| $3,500 | 24 months | $84,000 | $336 |
| $5,000 | 12 months | $60,000 | $240 |
| $8,000 | 24 months | $192,000 | $768 |
| $3,500 | 60 months | $42,000 × 4 = $168,000 (AAR × 4) | $672 |
| $12,000 | 36 months | $432,000 | $1,728 |

Why stamp duty matters
- Court admissibility — Section 52 of the Stamp Duties Act bars unstamped documents from being admitted as evidence. If the landlord later sues for unpaid rent or breach, an unstamped TA cannot be exhibited until duty + penalty is paid.
- HDB approval — for HDB rentals, HDB requires a stamped TA before approving the rental.
- Employment Pass evidence — some expat tenants need proof of accommodation (a stamped TA) for visa applications.
- Bank account / utility set-up — opening accounts or utility services may require a stamped TA as proof of address.
