A tenancy agreement is the contract that governs every residential lease in Singapore, from an HDB room let to a condominium on a two-year term. It records who occupies the property, on what terms, for how long, and at what rent, and it becomes the single document both sides reach for when a deposit dispute or an early termination lands on the table. Most tenants and landlords focus on the rent and the handover date, then treat the paperwork as a formality. That is where avoidable trouble starts. A lease that is not properly drafted and stamped with the Inland Revenue Authority of Singapore (IRAS) can be challenged clause by clause, and an unstamped one cannot even be used as evidence in court. This guide walks through the legal framework, the stamp duty rules that catch out so many first-time landlords, and the obligations that bind both parties from the day the agreement is signed.
What a tenancy agreement actually does
A tenancy agreement creates a leasehold interest: the landlord grants the tenant exclusive possession of the property for a fixed term in return for rent. In Singapore the document is often called a lease or a Tenancy Agreement (TA), and the two terms are used interchangeably in practice. The agreement is the source of almost every right and duty between the parties, which is why a vague or borrowed template causes so much grief later.
The TA should pin down the parties and the demised premises, the term and any renewal mechanism, the rent and the payment schedule, the security deposit, and the allocation of responsibility for repairs, utilities and aircon servicing. It is also the place to record who bears the stamp duty, the conditions of any diplomatic or early-termination clause, and the inventory of furniture and fittings handed over at the start. A well-drafted agreement reads less like a wish list and more like a set of instructions that a stranger could follow if the parties fell out. In practice, the disputes that reach mediation almost always trace back to a term that was left to a verbal understanding, the deposit deductions or the notice period being the usual culprits.
Legal framework: the Stamp Duties Act and IRAS
Stamping is governed by the Stamp Duties Act 1929, administered by IRAS, and it is the single most misunderstood obligation in the whole tenancy process. Stamp duty is a tax on the lease document, not on either party personally, and the lease duty is calculated on the Average Annual Rent (AAR), taken as the higher of the contractual rent or the open-market rent for the premises. Where the AAR does not exceed one thousand dollars a year, no duty is payable, a threshold almost every genuine residential let in Singapore will clear.
The rate structure is tiered. For a lease of up to four years, the duty is 0.4 percent of the total rent payable over the term. For a lease that runs beyond four years, or for an indefinite or perpetually renewable lease, IRAS caps the chargeable period: the duty is 0.4 percent of four times the AAR, so a ten-year lease is taxed as though it were four. The deadline is unforgiving. Duty must be paid within fourteen days of signing if the agreement is executed in Singapore, or within thirty days if it is signed overseas. Late stamping draws a penalty that escalates with the delay, running from a nominal sum for a short slip to several times the duty itself once the delay stretches past six months. By convention the tenant pays, and the TA should say so expressly, but the Stamp Duties Act makes the parties jointly liable, so a landlord cannot safely assume the matter is none of their concern. The authoritative reference for rates, exemptions and deadlines is the IRAS guidance on stamp duty for renting a property. Stamping is completed online through the IRAS e-Stamping portal, which issues a Stamp Certificate that should be kept with the signed agreement.
Why stamping decides whether your agreement holds up
The practical sting of an unstamped lease appears at the worst possible moment, when a dispute breaks out. An agreement that has not been duly stamped cannot be admitted as evidence in court proceedings, which means a landlord trying to enforce a rent arrears claim, or a tenant fighting an unfair deposit deduction, may find the very document they are relying on shut out until the outstanding duty and penalty are paid. The agreement does not become void, but its evidential value evaporates at the precise point it matters most.
Renewals and variations carry their own trap. A renewal, whether papered through a fresh tenancy agreement or a letter of intent that the parties act on, triggers a new stamping obligation on the new term. A variation that increases the rent or extends the term can attract additional duty. Treat every renewal as a fresh document for stamp duty purposes and stamp it within the same fourteen-day window. The rules apply identically to HDB and private property; there is no separate residential carve-out, and the 0.4 percent rate is blind to the type of dwelling. A clean IRAS-ready tenancy agreement for HDB and condo lets and a properly completed tenancy stamp duty pack aligned to the Stamp Duties Act 1929 keep both obligations in step.
Deposits, repairs and the obligations that bite later
Beyond stamping, the substance of the agreement decides how smoothly a tenancy runs. The security deposit, customarily one month's rent for each year of the term, is the landlord's cushion against damage and unpaid rent, and it is the most frequent flashpoint at handover. The deposit clause should state plainly what may be deducted, distinguish fair wear and tear from damage, and fix a timeframe for the refund after the tenant moves out. A move-in inventory with dated photographs is worth more than any amount of careful drafting when the parties later disagree about a scuffed wall or a stained sofa.
Repair obligations deserve the same precision. Singapore leases usually split responsibility by a monetary threshold, with the tenant covering minor repairs up to a stated figure per incident and the landlord shouldering structural and major items, alongside a defined aircon servicing schedule. The agreement should also address utilities accounts, internet, the consequences of late rent, and the notice required to end the tenancy. Where a diplomatic clause is included, allowing an expatriate tenant to terminate early on relocation, its trigger conditions and notice period must be spelled out word for word, because a loosely worded clause invites exactly the argument it was meant to prevent. Landlords letting a single room rather than a whole unit should work from a room rental agreement built for HDB and private lets, which handles shared-space obligations that a whole-unit lease does not.
Generating a compliant tenancy agreement on Captain.Legal
Drafting a lease from a generic template found online is how outdated clauses and missing obligations creep in. The Captain.Legal generator works the other way round, asking about the property type, the term, the deposit and the specific arrangements for repairs and servicing, then assembling a tenancy agreement whose clauses match current Singapore practice and the Stamp Duties Act framework. You begin by selecting whether you are letting an HDB flat, a condominium unit or a single room, since the obligations differ, and the document adjusts the relevant clauses accordingly.
From there the generator lets you set the rent and payment schedule, record the security deposit and its deduction terms, and state expressly that the tenant bears the stamp duty. The output is ready to download in Word and PDF, so you can make final adjustments before signing and keep a clean copy for the IRAS Stamp Certificate. The same flow covers the documents that sit alongside a lease, from a letter of intent to rent a property at the negotiation stage through to a rent receipt at the end. The point is autonomy: a landlord can produce a legally grounded agreement without paying for a lawyer to draft each one from scratch, while keeping the precision that protects both sides.
Common mistakes landlords and tenants make
The first and costliest error is missing the stamping deadline, usually because both parties assumed the other would handle it. Because liability is joint, a landlord who relied on the tenant to stamp can still be pursued for the penalty, so the safest practice is to confirm the Stamp Certificate has been issued rather than trust an assurance. The second recurring mistake is reusing an old template, often one drafted years earlier or borrowed from a different property, which leaves out obligations the parties later wish they had captured.
A third trap is the vague deposit clause that says nothing about what counts as fair wear and tear, guaranteeing an argument at move-out. Closely related is the failure to take a dated inventory, which turns the deposit dispute into one person's word against another's. Tenants, for their part, frequently sign without reading the diplomatic or early-termination clause, then discover on relocation that the notice period or trigger conditions do not work as they assumed. Finally, parties forget that a renewal is a fresh stamping event and let the new term run unstamped, quietly recreating the evidential problem they avoided the first time. None of these is exotic; they are the everyday failures that fill the mediation calendar, and every one of them is preventable with a properly drafted and stamped agreement. For landlords managing the end of a tenancy, a notice to quit that complies with section 18 of the Conveyancing and Law of Property Act avoids a parallel set of procedural errors.
Frequently asked questions
Is a tenancy agreement legally valid in Singapore if it is not stamped?
The agreement itself remains a valid contract between the parties, but stamping is what gives it teeth. Under the Stamp Duties Act 1929, an unstamped tenancy agreement cannot be admitted as evidence in court, so if a dispute over rent, deposit or early termination ends up in proceedings, the document you are relying on may be shut out until the outstanding duty and any penalty are paid. In practice that makes stamping essential to enforceability rather than optional. You can pay the duty late and have the agreement stamped afterwards, but you will face an escalating penalty, so stamping within the deadline is always the cleaner route.
How much stamp duty do I pay on a Singapore tenancy agreement?
For a lease of up to four years, the duty is 0.4 percent of the total rent payable over the whole term, calculated on the higher of the contractual rent or the market rent. For a lease running beyond four years, IRAS caps the calculation at four times the Average Annual Rent, so longer leases are not taxed indefinitely. If the AAR does not exceed one thousand dollars a year, no duty is payable, though that threshold is rarely relevant to a genuine residential let. The rate is the same for HDB flats and private property, with no distinction by dwelling type.
What is the deadline to pay tenancy stamp duty?
Stamp duty must be paid within fourteen days of signing the agreement if it is executed in Singapore, or within thirty days if it is signed overseas. Missing the deadline triggers a penalty that grows with the length of the delay, starting small for a short slip and rising to several times the duty once the delay passes six months. Because the Stamp Duties Act makes landlord and tenant jointly liable, neither party should assume the other has dealt with it; confirm the Stamp Certificate has been issued.
Who pays the stamp duty, the landlord or the tenant?
By long-standing convention in Singapore the tenant pays the stamp duty, and a well-drafted agreement states this expressly. Legally, however, the parties are jointly liable under the Stamp Duties Act, which means IRAS can pursue either of them if the duty goes unpaid. The sensible approach is to record clearly in the agreement that the tenant bears the cost, and for the landlord to verify that stamping has actually been completed rather than rely on an informal promise.
What format can I download my tenancy agreement in?
A tenancy agreement generated on Captain.Legal can be downloaded in both Word and PDF. The Word version lets you make any last adjustments before signing, while the PDF gives you a clean, fixed copy to sign and store. Keeping the signed agreement together with the IRAS Stamp Certificate is good practice, since you may need to produce both if a dispute arises or when the tenancy is renewed.
Do I need to stamp the agreement again when I renew the lease?
Yes. A renewal is treated as a fresh document for stamp duty purposes, whether it is papered as a new tenancy agreement or implemented through a letter of intent to rent that the parties act on. The new term must be stamped within the same fourteen-day window, with the duty calculated on the rent for that renewed period. A variation that increases the rent or extends the term during an existing lease can also attract additional duty, so it is worth checking the position whenever the terms change.
Does stamp duty apply to HDB room rentals as well as whole units?
Yes. The rules under the Stamp Duties Act apply to leases of immovable property regardless of whether you are letting an entire HDB flat, a private condominium or a single room. The 0.4 percent rate and the AAR exemption threshold work the same way; what differs is the substance of the agreement, since a room rental involves shared-space obligations that a whole-unit lease does not. If the Average Annual Rent on the room exceeds one thousand dollars, the lease is chargeable and must be stamped within the deadline.
Can a verbal tenancy agreement be enforced in Singapore?
A verbal agreement can in principle create a tenancy, but it is a poor foundation in practice. Without a written document there is nothing to stamp, no agreed record of the deposit terms, the repair split or the notice period, and no way to produce reliable evidence if the relationship breaks down. Almost every tenancy dispute that proves difficult to resolve traces back to a term left to a verbal understanding. A written, stamped agreement is the only sensible course, and for shared arrangements a dedicated room rental agreement removes the ambiguity that a handshake leaves behind.
