Letting a Shop, Office or Warehouse in Istanbul

You bought a shop or an office in Istanbul because the yield looked better than a flat's. Then the first serious candidate arrives and nothing matches what you learned about letting apartments: a ten-year term, a tax deducted before the rent reaches you, a question about VAT invoices, and an offer of turnover share instead of a fixed monthly rent.

Commercial letting is a different game from residential letting, and nearly all of it is decided in the week before signature.

Tax: settle withholding and VAT before you quote a rent

Stopaj (withholding tax)

If the property belongs to an individual and the tenant is a company or registered business, the tenant deducts income tax at source from the gross rent. This is stopaj, and the tenant pays it to the tax office in your name. What reaches your account is the net figure.

Hence the commonest misunderstanding in negotiation: the tenant says "the rent is 50,000 lira" meaning net, and you hear gross. At 20% as of 2026, 50,000 net is 62,500 gross, a quarter more. Have the lease state which figure it is, and check the withholding is actually paid over; it is filed in your name.

For a non-resident this is usually good news: Turkish law generally treats income already fully taxed at source as needing no annual declaration. What does not carry over is the exemption sheltering a slice of residential rent. It does not reach commercial rent at all. Both mechanisms are in rental income tax in Turkey. Confirm your case with an accountant: it turns on residency, not your passport.

KDV (VAT)

If the property is held by a company, the rent is invoiced with VAT; where it belongs to an individual, VAT normally does not arise but withholding does. This shapes who rents from you: corporate tenants often prefer a landlord who can issue an invoice, and a foreign individual with no Turkish company has no invoice book. Take that structuring decision with an accountant before you market the unit. The arithmetic of both taxes is worked through in withholding tax and VAT on commercial rent.

Lease term: ten years binds you too

Residential letting runs on one-year contracts. In commercial, 5+5 or ten-year terms are ordinary requests: the tenant is spreading fit-out and brand investment over a long horizon. A long lease removes vacancy risk and lifts value: a unit let to a corporate tenant prices higher with banks and valuers than the same unit empty. But the lease also locks in whatever you signed, and you cannot take the property back when you change your mind.

So the heart of a long lease is the increase clause.

TÜFE indexation. Turkey's Code of Obligations caps renewal increases at the twelve-month average consumer price index for roofed workplaces exactly as it does for homes; "40% a year" written into a shop lease is not enforceable. See the legal rent increase cap.

A market-rent reset. A rayiç güncellemesi at, say, year five resets the rent to the going market figure, instead of compounding an index for a decade with no reality check.

Foreign-currency indexation. Do not assume you can price a Turkish lease in euros to escape lira inflation. Turkey restricts foreign-currency lease pricing between parties who count as residents of Turkey (an exchange-control test, not a citizenship one). A clause that fails converts to lira, which is exactly the protection you thought you had bought.

Every other clause worth arguing over is in the essential clauses of a Turkish lease.

The tenant is the asset

The tenant sets value as much as the rent does: the same shop prices higher on sale let to a national chain on a ten-year lease than to a sole trader fighting to stay open. All of it is checkable on documents, from abroad.

• Company age, trading history, and the vergi levhası — the tax registration certificate every Turkish business holds, showing declared turnover for recent years.
• The trade registry record, and confirmation that whoever signs is an authorised signatory. A lease signed without signing authority is a fight you do not want.
• Capacity to provide a bank guarantee letter (teminat mektubu) or a strong guarantor.
• Whether the business suits the unit and the building: smell, noise, waste, and the licence the activity needs.
• The durability of their sector. If the tenant's business fails, your shop is empty again.

The classic dilemma is a lower offer from a corporate tenant against a higher offer from a risky one; over ten years the first usually wins. These checks are tenant screening applied to a company instead of a household.

High street, mall, wholesale centre or office?

High street shop. You contract directly, on flexible terms. Footfall, frontage width and window visibility set the price: rent can halve between a busy corner and a unit fifty metres down the same street, so a district average tells you nothing about your door.

Mall unit. Rent is usually turnover rent plus a base rent, the common charge (aidat, the building service charge) is heavy, and the mall's brand-mix policy can veto tenants you would happily accept. High return potential, low freedom.

Wholesale centres and neighbourhood bazaars. In İstoç-style complexes the tenant pool is sector-specific and value follows the traffic of your own block and corridor. Reaching that segment is local knowledge, not advertising spend.

Office. A plaza floor, a "home-office" (a flat in a residential block permitted for office use) and a standalone office building are three separate markets. Corporate tenants ask about parking, a backup generator, fire-regulation compliance and invoicing; fail those and you compete on price instead.

Eviction is slower here, so build the protections in first

A workplace tenant has the same strong statutory protection a residential tenant does. You cannot recover the unit merely because the fixed term ended. The lease renews by itself, year after year, and only after it has renewed for ten years can you end it by notice alone. Tenants who are merchants or companies used to be partly outside the tenant-protection rules; that exception has expired, so do not assume a commercial lease can be drafted freely.

• A notarised vacate undertaking (tahliye taahhütnamesi) with the dates correctly constructed. Get the dates wrong and the document is worthless.
• A bank guarantee letter, or a deposit on clear written terms.
• Rent through the bank, with a reference on every transfer. That is evidence, and also a rule: cash rent exposes both sides to penalties, as set out in the cash rent penalty.
• An explicit ban on subletting and assignment. Assignment, and the key-money payment attached to it (hava parası), arises far more often here than in residential letting: without the clause your tenant can sell their position in your shop and keep the premium.

An empty shop costs more than an empty flat

The aidat and the taxes keep running, a dark window wears down the unit's reputation, and offers on a shop empty for months get steadily worse. Property tax bites harder too: a workplace is taxed at a higher rate than a home, and metropolitan municipalities such as Istanbul charge double. Price off completed commercial lettings per square metre — a hopeful asking price can sit on a portal for a year without ever being tested.

The file to prepare before the first viewing

One missing item ends the process: a unit designated "dwelling" means a tenant who will never get an opening licence, and if that surfaces after terms are agreed you start from zero. You or someone holding your power of attorney can obtain all of these — before you market the unit, not when a candidate asks.

If you would rather hand it over

Commercial letting asks more than residential does: a tax structure, a contract architecture, real intelligence on the tenant. For shop and office owners we cover finding the tenant, structuring the lease and managing the rent afterwards; the scope is on the services page. Nothing is payable up front, and on a letting the service fee is one month's rent plus VAT, paid by the tenant. For a whole building, a plaza floor or an entire bazaar, that scale is project sales and leasing. To fix your unit's current rental and sale value, a free valuation request is enough.

In commercial property a good lease is worth more than a good rent. The rent is revised every year. A badly built lease you live with for ten.
