What is Instalment sale in Thailand?

Fact-checked by a REMAX Thailand Real Estate Expert

The Definition

In the Thailand property market, an instalment sale (often spelled installment sale) refers to a payment arrangement where the buyer pays the purchase price in scheduled installments to the seller or developer. This is common in new property developments, particularly off-plan condominiums. Payments typically include a reservation deposit, a contract signing fee, and progress-based tranches tied to construction milestones, with the final balance due upon ownership transfer at the Land Department. Ownership transfer typically occurs only after full payment, distinguishing it from lump-sum transactions.

Global Expectations vs. Thai Reality

Western buyers might expect installment sales to offer tax deferral benefits for sellers (e.g., spreading capital gains over years as in the US), but in Thailand, the Revenue Department requires taxes on the full sale price upfront, not just received installments, eliminating such deferral. Liability risks are higher for buyers without mandatory escrow, as payments go directly to developers' accounts, unlike protected structures in many Western markets. Legal enforcement favors developers, with court recovery being lengthy and uncertain compared to swift remedies abroad.

The Problem It Presents

Buyers risk losing deposits or installments if developers delay projects or go bankrupt, as payments are direct to developer accounts without automatic escrow protection. Sellers face tax burdens on the full price immediately, regardless of cash flow, per Revenue Department rules, potentially straining liquidity. Unexpected costs arise from interest post-construction or legal fees for disputes, with Thai courts slow to enforce buyer claims.

Foreigner vs. Thai Citizen Rules

Rules are similar for both, as installment plans are contractual and not restricted by nationality, though foreigners are limited to condos (not land/houses) under the Condominium Act. Thai citizens may access bank mortgages more easily for installment-like financing, while foreigners face stricter criteria (e.g., employment in Thailand), often relying on developer plans instead. Tax implications apply equally, but foreigners must comply with Foreign Business Act restrictions on ownership.

The Thai Legal Context

Governed by the Civil and Commercial Code (e.g., mortgage payoff by installments under Sections 713-714), Condominium Act (payment schedules for off-plan units), and Revenue Department regulations like No. Taw. Paw. 1/2558, which mandate revenue recognition per installment or full contract terms for tax purposes. The Department of Lands handles final ownership transfer post-full payment, while the Escrow Business Act 2008 allows but does not require escrow (only by licensed banks).

Benefits & Risks

Advantages

  • Enables affordability for buyers via interest-free plans during construction, requiring only passport copies.
  • Provides developers cash flow for project funding without bank loans.
  • Flexible milestones (e.g., 10-20% deposit, progress payments) suit off-plan purchases.

Risks & Disadvantages

  • No mandatory escrow heightens buyer exposure to developer default.
  • Sellers taxed on full value upfront, no deferral like in some countries.
  • Post-completion plans may add progressive interest, inflating costs.

Showcase: How It Works

Let’s look at a real-world scenario to understand how Instalment sale is applied during a property transaction.

The Scenario

  • A foreign expat buys an off-plan studio condo in Phuket for 3,571,440 THB.
  • Payment: 150k deposit; 35% on contract; 20% at start; 20% at structure completion.
  • Remaining 28% (992,860 THB) paid only upon handover and Land Department transfer.

The Result

Total paid matches 3,571,440 THB; ownership transfers only after final payment, with developer withholding title until cleared.

Outcome:Total Paid: 3,571,440 THB (Title Transferred)

Real-Life Case Study

The Situation: A buyer paid 30% installments (9 million THB) on a Bangkok off-plan condo before the developer stalled construction.

The Challenge: Without escrow, the buyer couldn't recover funds easily, facing years of litigation under Civil and Commercial Code.

The REMAX Difference:
A REMAX Thailand agent insists on escrow via a licensed bank under Escrow Act 2008 and vets developer licenses to prevent loss.

Frequently Asked Questions

Are developer installments interest-free?
Yes, typically during construction for off-plan condos, but post-completion plans add progressive interest over 3-5 years.
Can foreigners use installment sales?
Yes, with just a passport copy for developer plans, though limited to condos; bank mortgages for ready properties need Thai employment proof.
What if the developer delays?
Payments aren't automatically refunded; pursue via court or contract clauses—escrow prevents this by holding funds.
How are taxes handled?
Sellers pay on full price per Revenue Department rules at contract, not per receipt; buyers face no direct tax on payments.
Is escrow mandatory?
No, but recommended under Escrow Act 2008—developers rarely offer it, routing payments to their accounts instead.

Why It Matters

Misjudging installment risks can lead to total deposit loss in developer failures, common in Thailand's off-plan market. Sellers ignoring full-tax liability upfront face cash shortages, jeopardizing deals.

💡 REMAX Pro Tip

Always demand escrow for installments over 10% via a BOT-licensed bank—it's your only shield against project delays, and negotiate milestone proofs in the contract.

Common Misconceptions

Myth: Sellers defer taxes until payments are received

Reality: Revenue Department taxes the full sale price at contract, not per installment receipt.

Myth: All payments are protected like in Western escrow systems

Reality: Payments go directly to developers; escrow is optional and rare under Escrow Act 2008.
