Rental stamp duty in Singapore is 0.4% of the Average Annual Rent (AAR) for leases up to 4 years. Leases longer than 4 years or indefinite are capped at 0.4% × 4 × AAR. Pay within 14 days of signing the TA (30 days if signed overseas). Most TAs have the tenant pay. Late filing penalty: up to 4× the duty if delay exceeds 3 months.
Rental stamp duty trips up more first-time tenants in Singapore than any other rental rule. The formula itself is simple — 0.4% of average annual rent — but the 14-day filing deadline, overseas-signed exception, and what counts as dutiable rent (furniture excluded, service charge maybe) create confusion. This guide explains the rules in plain English with three worked examples.
The 0.4% formula with three worked examples across HDB, condo, and landed
The formula
For a tenancy agreement with a fixed term:
Stamp Duty = 0.4% × Average Annual Rent (AAR) × Duration (in years) Where AAR = Total rent over lease period ÷ Lease length in years
If the lease is longer than 4 years, or is indefinite/renewable, the multiplier is capped at 4:
Stamp Duty = 0.4% × 4 × Average Annual Rent
Three worked examples
Example 1 — HDB room, 1-year lease at S$1,200/month
AAR = S$1,200 × 12 = S$14,400
Duty = 0.4% × S$14,400 × 1 year = S$57.60
Example 2 — Condo unit, 2-year lease at S$3,800/month
Under the Stamp Duties Act, either party can pay — the TA dictates who. Market convention in Singapore is tenant pays, but always check the clause. If the TA is silent, the party presenting it for registration pays.
Within 14 days of signing if the TA is executed in Singapore.
Within 30 days if signed overseas.
You’ll need SingPass or a CorpPass login. IRAS sends the stamp certificate by email — store it with your TA.
Late payment penalties
Delay
Penalty
Up to 3 months late
S$10 or the duty amount (whichever is higher)
More than 3 months late
S$25 or 4× the duty amount (whichever is higher)
Beyond the fine, an unstamped TA cannot be used as evidence in court — so if you ever dispute a deposit refund or breach claim, your unstamped TA is worthless until you stamp it (and pay the late penalty).
What is and isn’t dutiable
Component
Dutiable?
Rent
Yes
Maintenance fee (if stated separately in TA)
No
Furniture rental (stated separately)
No
Utility estimates bundled in rent
Yes (if not separated)
Security deposit

Frequently asked questions
Does the stamp duty increase if rent changes mid-lease?
Only if there’s a written variation to the TA. Automatic CPI-linked increases written into the original TA are captured in the AAR calculation when you stamp at signing.
Do I need to stamp a room-only rental?
Yes — any tenancy agreement, including for a single room, is dutiable. The duty amount will just be smaller.
Can I deduct stamp duty from my income tax?
If you paid the stamp duty as a landlord, it’s a deductible rental expense. If you paid as a tenant (and the property isn’t used for business), it’s not deductible.
What if both parties refuse to pay?
Either party can pay and recover from the other. The TA itself cannot be enforced in court until stamped, so the party needing legal enforcement usually ends up paying.

Renting a home in Singapore usually takes 3–4 weeks. Budget roughly 3–4 months’ rent in cash upfront (first month + 1–2 months’ security + stamp duty + any agent fee), sign a tenancy agreement within 14 days of the LOI, and stamp it within 14 days of signing. At exit, expect your security deposit back within 14–30 days of a clean handover.
Whether you’re a local family bridging between homes, a PR upgrader, or an expatriate signing your first Singapore lease, the rental process runs on the same five-step rails. The rules are not complicated, but the upfront money moves fast and the deposit mechanics catch people out at exit. This tenant guide walks you through the full journey, the contract clauses that matter, and how to get every dollar of your security deposit back.
The five-step rental journey and upfront cash needed to move in
Step 1: Letter of Intent (LOI) + good-faith deposit
Once you’ve viewed a property and agreed to rent it, you (or your agent) sends the landlord a Letter of Intent. The LOI sets out the rent, tenancy length, lock-in period, diplomatic clause (for foreigners on work pass), inclusions (aircon servicing, white goods, furniture), and any special requests (painting, pest treatment, replacing faulty items).
You pay a good-faith deposit equal to one month’s rent when the LOI is signed. This is converted to the first month’s rent when the TA is signed. If the landlord backs out, you get it refunded; if you back out, you forfeit it.
Step 2: Tenancy Agreement (TA)
Within 14 days of the LOI, the landlord’s lawyer or agent drafts the Tenancy Agreement. Read it carefully before signing. The clauses that matter most:
Security deposit: Market norm is 1 month per year of lease, capped at 2 months. Refuse anything higher.
Diplomatic clause: Lets a foreign tenant break the lease if their work pass is revoked or they’re transferred overseas, usually after a 12-month minimum stay and with 2 months’ notice.
Minor repair threshold: Repairs below S$150–200 are usually the tenant’s responsibility; above that, it’s the landlord’s. Make sure this threshold is explicit.
Lock-in period: The period during which neither party can terminate. Usually the full lease term for fixed leases, or 12 months of a 24-month lease.
Subletting: Almost always prohibited without written consent. Don’t list the unit on Airbnb.
Step 3: Stamp duty (within 14 days)
The tenancy agreement must be stamped with IRAS within 14 days of signing in Singapore (30 days if signed overseas). The duty is 0.4% of the average annual rent for leases up to 4 years. For most Singapore TAs, the tenant pays — check the TA. File via the IRAS e-Stamping portal. The full formula with worked examples is in our rental stamp duty guide.
Step 4: Handover and inventory check
On move-in day, do a joint inspection with the landlord or agent. This is the single most important step for protecting your deposit at exit:
Photograph every existing scratch, stain, chip, and mark in every room.
Note the condition of all appliances — test the aircon, oven, hob, washing machine, dryer, fridge.
Take meter readings for electricity, water, and gas.
Sign the inventory list — don’t leave any item unticked.
Keep digital copies of everything, dated.
Step 5: Exit and deposit return
Give 30 days’ written notice before lease expiry (check your TA — sometimes 60 days). Do a joint handover check on your last day. If the landlord flags damage beyond fair wear-and-tear, negotiate from your move-in photos. The deposit must be returned within 14–30 days of the final handover per standard Singapore TAs.

A S$3,800/month condo with a 2-year lease typically needs roughly S$12,500–S$13,500 in cash at the start — be ready before you start viewing.
Getting your deposit back in full
Three rules of thumb:
Professionally clean before handover. S$250–S$450 for a 3-bedder is standard — deducted from deposit if you skip it.
Serve aircon units. Under most TAs, the tenant must service aircon at least once every 3 months and produce receipts at handover.
Minor wall-fill and touch-up paint. Hole from a TV mount or picture hook? Patch it before inspection.
Frequently asked questions
Can the landlord refuse to return my deposit?
Only for documented breaches (unpaid rent, damage beyond wear-and-tear, unpaid utilities). They must itemise deductions in writing. Disputes above S$20,000 go to the Small Claims Tribunals or civil court; the stamped TA is your main evidence.
What counts as fair wear-and-tear?
Minor scuff marks, slight carpet flattening, faded paint from sunlight, light furniture indents on floors. What’s not fair: burn marks, broken fittings, unapproved modifications, pet damage (unless pets were allowed in the TA).
Do I need a property agent as a tenant?
Not mandatory, but agents help with contract negotiation, market rent benchmarking, and dispute handling. If both parties have their own agents, each pays their own. Using the landlord’s agent (“co-broke”) is free for you but they represent the landlord.

99-to-1 property ownership is a structure where one party holds a 99% interest in a property and another holds 1%. It came under intense IRAS scrutiny in 2023–2024 when the tax authority identified a specific pattern being used to sidestep Additional Buyer’s Stamp Duty (ABSD). This 2026 guide separates legitimate 99-to-1 arrangements from the red-flag pattern IRAS has been reassessing, and explains how it differs from classic decoupling.
For the official IRAS guidance, see IRAS’s stamp duty page. This article explains the practical picture.
Quick Answer — 99-to-1 in 2026
The structure: one party holds 99% of a property, another holds 1%.
Legitimate uses: loan eligibility, succession planning, investment allocation among co-owners.
The flagged pattern: sole buyer signs OTP, then transfers 1% to another party within weeks.
Clawback: original ABSD + 50% surcharge = 1.5x the amount saved.
Different from decoupling: 99-to-1 happens at original purchase; decoupling happens long after purchase.
The red-flag pattern: a two-stage transfer executed within weeks of the original OTP.
Why 99-to-1 Became Attractive
A standard 99-to-1 structure lets two parties co-own a property with minimal share for one. In isolation this is unremarkable — people use it for tax planning, succession, and pooled investment.
Under Singapore’s ABSD framework, though, it can also function as a loan-qualification tool. Here is the pattern IRAS identified:
A buyer without enough income to qualify for a large bank loan wants to buy a S$2m condo.
A family member with high income but who already owns a property agrees to be named on the loan.
The high-income family member was added as a co-owner at 1%, while the main buyer takes 99%.
The bank was willing to lend based on both incomes because the family member is a co-owner.
But because the family member only owned 1%, the buyer’s main ownership would have qualified for first-timer ABSD treatment.
The effect: a high-income co-owner who already owned property was piggybacking on a first-timer buyer’s ABSD rate. IRAS identified this as a tax-avoidance pattern under the general anti-avoidance provision.
The IRAS Audit Pattern
IRAS has been targeting a specific variant of 99-to-1:
Sole buyer signs the OTP and pays BSD on the full purchase price at first-timer rates.
Within weeks of OTP, a 1% share is transferred to a second party (often a spouse or parent).
The 1% transferee already owns another property — they would have triggered ABSD if they had been on the OTP from day one.
The two-stage structure avoids the ABSD that a direct joint purchase would have incurred.
IRAS reviewed approximately 300–400 such cases in its 2023–2024 sweep. Where the pattern matched, IRAS reassessed the transaction as if the 1% transferee had been a co-owner from the start, and issued an ABSD bill plus surcharge.
The 1.5x Clawback
When IRAS reassesses a 99-to-1 arrangement as tax avoidance, the remedy is:
The full ABSD that would have applied had the transferee been on the OTP from day one
Plus a 50% surcharge on that ABSD
On a S$2m purchase where avoided ABSD was 20% = S$400,000, the clawback works out to S$400,000 + S$200,000 surcharge = S$600,000 payable, plus any interest and legal costs. This is materially more punitive than simply paying the ABSD upfront.
Legitimate 99-to-1 Arrangements
Not every 99-to-1 is a red flag. IRAS has explicitly acknowledged the pattern is legitimate when:
Both parties are co-owners from day one
If both parties sign the original OTP and are named as co-owners in the Sale & Purchase Agreement at the 99:1 split, this is a single transaction and the full ABSD applies on the 1% transferee’s share from the outset. No two-stage manoeuvre, no IRAS issue.
Genuine investment-pooling
Multiple family members pooling funds for an investment property, with each contributing in proportion to their share, is legitimate — provided the shares reflect actual contribution.
Succession planning
A parent retaining 99% and transferring 1% to a child for succession reasons is legitimate, subject to the normal BSD on the 1%. Timing is usually far removed from any property transaction, which is itself a credibility signal.
Commercial co-ownership
Business partners sharing an investment property where one partner provides 99% of the capital and the other provides 1% (perhaps in exchange for operational management) is legitimate under normal commercial logic.

2023–2024 sweep
Reviewed case-by-case
Put simply: decoupling restructures an existing joint ownership; the flagged 99-to-1 pattern manipulates a fresh purchase to sidestep ABSD that would otherwise have applied.
If You Already Have a 99-to-1 Arrangement
If you set up a 99-to-1 before 2023–2024 and have not heard from IRAS, it is almost certainly not in the audit scope. However, if you receive an IRAS query letter:
Do not respond on an informal basis. Engage a tax-focused solicitor immediately.
Compile the documentary evidence for the legitimate commercial purpose of the arrangement.
Be ready to pay the full clawback + surcharge if the pattern matches the flagged type. Appealing is expensive and the success rate has been low.
Consider restructuring if the arrangement is ongoing — though retrospective fixes rarely help once IRAS has engaged.
Current Status in 2026
As of 2026, IRAS continues to monitor two-stage transfers with a 1% residual. The 2023–2024 sweep was not a one-off — it set a precedent that routine transaction audits now look for. Structures that superficially resemble the flagged pattern are far riskier than they were before 2023.
For buyers with legitimate pooling or succession reasons, the arrangement remains viable — but put the co-owner on the original OTP, keep documentation of commercial intent, and avoid the tell-tale timing pattern.
FAQ — 99-to-1 2026
Is 99-to-1 illegal?
No. The ownership structure itself is legal. What is scrutinised is whether the specific arrangement amounts to tax avoidance under the general anti-avoidance provision.
Can I still use 99-to-1 today?
Yes, provided both parties are on the original OTP and the arrangement has a genuine commercial purpose. The risky pattern is the two-stage transfer executed soon after OTP.
How does IRAS identify flagged arrangements?
By cross-referencing stamp duty records with property ownership data. If you owned property before the 1% transfer date, IRAS’s system will flag the transaction for review.
What about 95-to-5 or 90-to-10?
The same anti-avoidance principle applies. IRAS has focused on 99-to-1 because it is the most extreme variant, but the logic extends to any split where a high-income party with existing property takes a minor share to piggyback ABSD rates.
Can I unwind an existing 99-to-1 to avoid IRAS attention?
Possibly, but consulting a tax lawyer before any action is essential. Unwinding can itself trigger stamp duty and CPF complications, and retrospective “fixes” are often viewed as evidence of avoidance intent.
