1. What the JS-SEZ is
The Johor-Singapore Special Economic Zone (JS-SEZ) is a framework agreed by the two governments to let companies run one operation across both sides of the Causeway: headquarters, finance and high-value services in Singapore; land-, labour- and power-intensive activities in Johor.
The agreement was signed on 7 January 2025, a year after the memorandum of understanding of January 2024. It covers about 3,500 km² of southern Johor, broadly Iskandar Malaysia plus Pengerang, and targets eleven sectors: manufacturing, logistics, food security, tourism, energy, the digital economy, the green economy, financial services, business services, education and health.
In practice it offers three things: targeted tax incentives, faster facilitation through a one-stop investment centre in Johor (IMFC-J), and better cross-border movement of people and goods.

2. The nine flagship zones
Each flagship zone has a job. The incentive in the middle column is the headline JS-SEZ incentive for that zone; the sector mapping on the right comes from the January 2025 announcement.
| Zone | Headline incentive focus | Sectors |
|---|---|---|
| A Johor Bahru Waterfront | Global Services Hub | Business services, digital economy, health |
| B Iskandar Puteri | Global Services Hub | Manufacturing, business services, digital, education, health, tourism |
| C Tanjung Pelepas | Smart logistics | Manufacturing, energy, logistics |
| D Tanjung Langsat – Kong Kong | Downstream specialty chemicals | Manufacturing, energy, logistics |
| E Senai – Skudai | Aerospace manufacturing and MRO | Manufacturing, digital, education, logistics, tourism |
| F Kulai – Sedenak | AI and quantum supply chain, medical devices, pharma | All sectors, including food security, energy and health |
| G Desaru – Penawar | Integrated tourism | Education, food security, health, tourism |
| H Pengerang | Oil, gas and petrochemicals (separate regime) | Manufacturing, energy, logistics |
| I Forest City | Special Financial Zone: family offices, fintech | Financial services |

3. Where things stand in 2026
- Incentives are live. The JS-SEZ incentive package took effect on 1 January 2025. Applications go to MIDA, before the project starts, until 31 December 2034.
- One-stop centre. IMFC-J, run by MIDA with IRDA and Invest Johor, brings ministries, the land office, local councils and utilities under one roof, with priority handling for Singapore companies. Singapore runs a JS-SEZ project office on its side.
- Master plan. The master plan is complete and approved by Cabinet. Its launch is expected in December 2026 at the Malaysia-Singapore Leaders' Retreat. It may add detail to zones or incentives, so plans made now should be re-checked then.
- RTS Link. The Johor Bahru – Woodlands North rail link is in testing. On 2 October 2026 the passenger launch was reported as targeted for mid-February 2027.
- Investment. The Economy Ministry reported RM 76.98 billion of approved JS-SEZ investment in 2025. Singapore companies have committed more than S$ 5.5 billion since January 2024.
- Data centres. Since November 2025 Johor has approved only air-cooled Tier 3 and Tier 4 data centres, to protect water and power.

4. What the JS-SEZ is not
- Not a free-trade or customs territory. Malaysian law, land rules, state consent and local approvals still apply in full.
- Not an automatic tax holiday. The special rates must be applied for, and most carry high thresholds, for example RM 500 million of capital expenditure for manufacturing in Senai–Skudai and Kulai–Sedenak. See Guide 03 for who realistically qualifies.
- Not a substitute for site due diligence. A site inside a flagship zone can still have the wrong land use, an unapproved extension or insufficient power.
5. How to use it in a location decision
Start with what your operation needs, not with the incentive. For most mid-sized companies the case for Johor rests on space, cost, workforce and proximity to Singapore; incentives improve a decision that already works. A sound sequence:
- Write a one-page brief: activity, specification, power, location constraints, timing, lease or buy, budget and decision-makers.
- Screen the zones against that brief: clusters, logistics, utilities and the incentives you can realistically use.
- Shortlist sites only after title, land use, approvals and power have been checked.
- Compare the full cost of each option, including stamp duty, state fees and fit-out, before negotiating.
