Organised Industrial Zone Incentives
Investing inside an organised industrial zone produces a different support table than investing outside one. We work out which rights apply to you, from land allocation to energy and property advantages.
Who it is for
Firms building inside an OIZ or considering a move into one.

What you end up with
- Land allocation application and review of allocation terms
- Calculating the additional support elements granted to OIZ investments
- Correspondence with zone management and infrastructure units
- Building permit and start of production follow up
The support an investment receives depends not only on what you produce but on where you produce it. An investment inside an organized industrial zone draws employer's share premium support on the terms of one region below its own. Tax and fee exemptions and ready built infrastructure add to that difference.
This page sets out where a zone location actually pays and how we run the process.
Three separate benefits
1. Incentives
Decree 9903 gives investments carried out in an organized industrial zone or an industry zone the employer's share premium support of one region below their own. Investing in the districts the decree lists moves it two regions. For investments in the sixth region, two years are added to the applicable duration.
One point deserves attention. Under the previous system, the zone based shift also covered the corporate tax reduction. In the decree now in force it is defined for employer's share premium support only, and a great deal of material online still describes the old rule.
In some sectors a zone is mandatory in any case. Investments in leather tanning, for instance, are supported only inside organized industrial zones.
2. Tax and fees
Zone legislation carries a set of exemptions for immovables and transactions inside the zone:
- Property tax: buildings inside a zone are permanently exempt. The five year temporary exemption that applied before 2017 was replaced; content still quoting "five years" is out of date.
- Fees: subdivision, merger, partition, transfer and registration transactions are exempt.
- Building construction and occupancy permit fees: structures built inside the zone are exempt.
- Stamp duty: contracts and undertakings on land allocation are exempt.
- Building inspection fee: reduced for structures inside zone boundaries.
- Wastewater fee: municipalities charge none where the zone operates its own treatment plant.
On energy there is no fixed statutory discount specific to zones; arrangements on participants' energy costs are made separately.
3. Infrastructure and operations
Roads, electricity, natural gas, water and wastewater infrastructure come ready. Treatment facilities are shared. Zoning and permit processes run through the zone administration rather than through separate dealings with a municipality. Having companies from the same sector nearby also shows up in supply and service costs.
Comparison
| Heading | Inside a zone | Outside a zone |
|---|---|---|
| Employer's premium support | Terms and duration of one region below | The province's own region |
| Infrastructure | Ready, shared cost | Investor's responsibility |
| Zoning and permits | Through the zone administration | Municipality and other authorities |
| Wastewater treatment | Shared facility | Your own plant |
| Land cost | Allocation procedure, varies by zone | Open market |
| Sector restriction | Set by the zone plan | None |
| Expansion | Depends on adjacent parcel allocation | Free if land is available |
This is a general frame. A real comparison weighs province, sector, energy requirement and logistics together.
What we do
Site analysis. We map the zones that fit your activity, comparing sector restrictions, available parcels, energy capacity and infrastructure charges.
Incentive calculation. We calculate which support elements the investment would draw in the chosen zone and in alternative locations, then the decision is made on that table.
Allocation application. We prepare the file the zone administration requires. Planned activity, employment and production figures are assessed here, and where free allocation is in play we calculate the minimum employment commitment tied to parcel size.
Permits. Zoning status, building permit, environmental permits and occupancy permit are tracked through to completion.
Incentive certificate. The investment incentive certificate application and everything after it is handled by the same team.
When a zone is not the answer
An organized industrial zone is not right for every investment. An outside location can make more sense where:
- Proximity to a raw material source is essential, such as mining, agricultural produce or water
- The zone's sector plan does not cover your activity
- The parcel size you need is unavailable in the zone
- Proximity to a port or border crossing is decisive
Conversely, where infrastructure costs are high, energy consumption is heavy or the process produces wastewater, the zone difference is usually decisive.
The call belongs to a calculation, not an instinct. In the feasibility study we set the two scenarios side by side: total investment cost, support received and the difference in ten years of operating cost.
For investors coming from abroad
If you are choosing a location in Türkiye for the first time, the practical questions are usually the same: which provinces carry which support group, how long allocation takes, what infrastructure costs on top of the land, and what the permit chain looks like. We answer those with sources before you commit to a site, and we can run the whole process in English.

Getting started
The first meeting covers the planned activity, capacity, energy and water requirements and the provinces you are considering. From there we produce the candidate zones and what each is worth on the incentive side. That first assessment is free.
