Turkey Commercial Lease Law Key Money Eviction 2026

1. Statutory Legal Foundation: Turkish Code of Obligations (TBK No. 6098)

Commercial leasing in Turkey operates under a codified framework balancing contractual stability with business continuity:

1. Turkish Code of Obligations No. 6098 (Türk Borçlar Kanunu - TBK):

• Article 344 (Determination of Rent & Statutory CPI Ceiling): Expressly stipulates that rent increase clauses in renewal periods cannot exceed the twelve-month moving average of the Consumer Price Index (TÜFE) of the preceding lease year. Any clause attempting to tie rent increases to foreign currency, fixed percentages exceeding TÜFE (such as 50% or 100%), or arbitrary formulas is invalid (*kesin hükümsüz*) and automatically drops down to the statutory TÜFE rate.
• Article 346 (Prohibition of Detrimental Clauses): Landlords cannot impose financial obligations beyond the base rent, statutory deposit, and common operating expenses (*aidat*). Article 346 invalidates penalty clauses for late payments (*cezai şart*) and acceleration clauses (*muacceliyet şartı*) claiming an entire year's rent upon a single late installment.
• Article 342 (Security Deposit Protection - Depozito): Limits cash security deposits to three months' rent. The deposit must be placed into a joint interest-bearing escrow account (*vadeli tasarruf hesabı*) redeemable only with mutual consent or a final court verdict.

1. Commercial Goodwill vs. Illegal Key Money (Hava Parası):

• Foreign investors often confuse illicit "key money" (*hava parası*) demanded under the table with legitimate "commercial goodwill" (*ticari işletme devir bedeli*).
• If a property owner demands unreceipted cash simply for granting a lease to an empty space, that payment violates Article 346 TBK. The tenant can recover the full amount via a lawsuit grounded in unjust enrichment (*sebepsiz zenginleşme*).
• Conversely, when an existing tenant transfers an operational venue with fixtures, licenses, and clientele (*goodwill*), this transaction is legally protected. It is executed via a "Commercial Enterprise Transfer Agreement" under TTK Article 11 or a "Lease Assignment" under TBK Article 323. Landlords cannot withhold consent without a documented, justifiable legal ground (*haklı sebep*).

1. Mandatory Mediation in Lease Disputes (Law No. 7445):

• Mandatory mediation is a prerequisite (*dava şartı*) for all commercial lease disputes, including eviction actions, rent determination lawsuits (*kira tespit davaları*), and deposit return claims before filing in Civil Peace Courts (*Sulh Hukuk Mahkemesi*).

2. Calculating the 12-Month TÜFE Cap, Withholding Tax (Stopaj), and VAT (KDV)

Corporate tenants in Turkey must account for the tax structure governing their leases, as it directly impacts net overhead:

Scenario A: Leasing from an Individual (Natural Person)

• Withholding Tax (Stopaj Vergisi): Corporate tenants must withhold 20% income tax at source and remit it to the Turkish Revenue Administration (GİB) via the withholding tax declaration (*Muhtasar Beyanname*).
• Net vs. Gross Calculation:
• If the contract specifies a "Net" rent: Gross Rent = Net Rent ÷ 0.80.
• Example: Net rent of 80,000 TRY = gross contractual rent of 100,000 TRY. The company pays 80,000 TRY to the landlord's IBAN and 20,000 TRY in Stopaj to the tax office. GARS lawyers ensure gross rent is explicitly documented in the lease to prevent tax disputes.

Scenario B: Leasing from a Corporate Entity or Business Center

• No Stopaj applies. The landlord company issues a corporate e-Invoice (*e-Fatura*) adding 20% Value Added Tax (KDV), which the tenant company deducts against its operational revenues (*İndirilecek KDV*).

Applying the Statutory TÜFE Ceiling in 2026:

• TÜİK publishes official inflation metrics on the 3rd day of each month. The binding benchmark is the "Change According to 12-Month Averages" (*On İki Aylık Ortalamalara Göre Değişim Oranı*).
• If a lease renews when the 12-month TÜFE average is 36.8%, the maximum legal increase is strictly 36.8%.
• If the landlord demands an increase of 75%, the tenant company is legally protected by depositing the previous rent plus 36.8% into the landlord's bank account with the description: "Lease payment for [Month/Year] including statutory TBK 344 TÜFE adjustment." This shields the tenant from default notices (*temerrüt ihtarı*).

3. Practical Procedural Walkthrough: Due Diligence, Drafting, and Registration

To protect foreign businesses from non-compliant zoning or fraudulent titles, GARS executes a five-stage protocol:

Step 1: Real Estate Title and Municipal Due Diligence

Before signing, GARS attorneys inspect property records via Web-Tapu to verify:

• Alignment between the landlord named in the lease and the titleholder on the deed (*Tapu Senedi*), or verify a notarized power of attorney authorizing leasing.
• Property classification: The title must designate the space as a "Shop" (*Dükkan*), "Office" (*Büro*), or "Workplace" (*İşyeri*). If registered as residential (*Mesken*), municipal authorities will deny an Operating License (*İşyeri Açma ve Çalışma Ruhsatı*) unless 100% of building owners sign a notarized consent resolution (*Muvafakatname*).
• Presence of the Occupancy Permit (*İskan*). Without an İskan, municipal departments frequently deny permanent commercial licenses.

Step 2: Drafting Protective Contractual Terms

• Permitted Use Scope: Drafting business purpose clauses broadly (e.g., "software engineering, corporate administration, international trade, warehousing, logistics, and consulting") to prevent landlords from claiming unauthorized usage.
• **Renovation Grace Period (*Tadilat Süresi*):** Securing a rent-free period of one to three months while completing interior architectural outfitting.
• **Interior Fixtures (*Faydalı ve Lüks Masraflar*):** Specifying whether permanent fixtures transfer to the landlord or can be removed, and preserving reimbursement rights under TBK Article 327.

Step 3: Notarization and Stamp Tax (*Damga Vergisi*)

Under Stamp Tax Law No. 488, corporate leases are subject to stamp tax at 1.89 per thousand (0.189%) of total gross contractual rent over the full term. This tax must be remitted within 15 days, serving as proof of registration for the Trade Registry (*Ticaret Sicili*).

The following table details statutory levies, notary expenses, and professional costs for a commercial lease of 75,000 TRY per month over a two-year contractual term:

5. Real-World Case Study: International Logistics Firm in Şişli, Istanbul

Background:

In early 2024, a foreign freight logistics company leased 250 square meters in Şişli, Istanbul, at 50,000 TRY monthly on a three-year contract. The company invested over 600,000 TRY in structural improvements, including high-speed fiber infrastructure, glass executive suites, server cooling, and fire suppression.

In 2025, upon the second contract year, the landlord demanded a 120% rent hike to 110,000 TRY and 400,000 TRY in cash "key money" (*hava parası*), threatening an eviction lawsuit alleging personal necessity for his son's consulting firm.

Legal Strategy Executed by GARS:

1. Application of Statutory CPI: GARS verified the official TÜİK 12-month average inflation rate (53.8%) and set the statutory rent at 76,900 TRY per month.
2. Bank Payment Compliance: The client remitted the exact statutory amount via corporate wire with the description: "Commercial rent including statutory TBK 344 TÜFE adjustment."
3. **Formal Notary Rebuttal Notice (*İhtarname*):** We served a formal notice citing TBK Article 346 regarding the illegality of key money, and highlighted TBK Article 355, which prohibits landlords from re-leasing a property for three years following an eviction for personal necessity under penalty of paying one year's full rent plus relocation damages.
4. Mandatory Mediation Defense: In mediation, GARS presented evidence proving the landlord's son was an undergraduate student abroad with no consulting business.

Outcome:

The landlord abandoned all key money claims. A binding mediation protocol (*Arabuluculuk Anlaşma Tutanağı*) was signed cementing the statutory TÜFE increase. The client retained the property, saving over 790,000 TRY in illegal rent demands and forced relocation expenses.

6. Commercial Lease Pitfalls and GARS Preventive Strategies

Foreign businesses navigating Turkish commercial leasing routinely encounter recurring risks:

Pitfall 1: Signing an Un-dated Eviction Undertaking (*Tahliye Taahhütnamesi*)

• The Risk: Landlords often ask foreign executives to sign an eviction undertaking with blank dates at lease signing. Later, the landlord fills in dates and initiates summary eviction via the Enforcement Directorate (*İcra Dairesi*) under TBK Article 352, giving the tenant 15 days to vacate.
• GARS Solution: Clients must never sign undated undertakings. When an undertaking is unavoidable, GARS ensures it is executed well after physical possession is transferred, with explicit conditions tied only to contractual default, or we gather evidence to challenge its validity in court based on coercion.

Pitfall 2: Paying "Key Money" (*Hava Parası*) in Cash Under the Table

• The Risk: Handing unreceipted cash to a departing tenant or landlord. If a dispute arises, the recipient denies receiving the funds, and tax auditors classify the transaction as tax evasion.
• GARS Solution: Commercial transfers are structured as notarized "Commercial Enterprise Transfer Agreements" (*Ticari İşletme Devir Sözleşmesi*). Equipment and assets are inventoried with invoices, and payments are transacted via corporate wire transfers.

Pitfall 3: Neglecting Technical Handover Protocols (*Teslim Tutanağı*)

• The Risk: Upon lease termination, landlords claim cosmetic wear-and-tear damages, seizing deposits and filing lawsuits for property destruction.
• GARS Solution: We prepare a photographic "Technical Handover Protocol" upon move-in, detailing the baseline condition. The lease explicitly states that ordinary commercial modifications do not constitute compensable property damage under TBK Article 335.

Pitfall 4: Missing Statutory Notice Deadlines for Renewal

• The Risk: Assuming the lease expires automatically on the end date. Under TBK Article 347, unless the tenant gives written notice at least 15 days prior to expiration, the contract extends automatically for one full year under identical terms.
• GARS Solution: GARS corporate compliance calendars track all notification windows, dispatching formal notary notices within statutory limits.

8. Frequently Asked Questions Regarding Turkish Commercial Leases

Q1: Can a commercial landlord increase rent to prevailing market rates after one or two years?

No. Under TBK Article 344, the landlord is restricted to the statutory 12-month average Consumer Price Index (TÜFE) ceiling for the first five years. A landlord cannot petition the courts for a market adjustment until five full years have elapsed, which requires filing a "Rent Determination Lawsuit" (*Kira Tespit Davası*) in Civil Peace Court, where court experts evaluate comparable properties while applying an equitable discount for tenant longevity.

Q2: What are the exclusive legal grounds for evicting a commercial tenant in Turkey?

Under TBK Articles 350 to 356, a commercial tenant can be lawfully evicted only on specific statutory grounds:

1. A valid written eviction undertaking executed after property delivery (TBK Art. 352/1).
2. Two justified notary default notices served in the same rental year for non-payment (TBK Art. 352/2).
3. Sincere, genuine, and mandatory personal need of the landlord, spouse, or direct descendants to conduct a trade or profession in that property (TBK Art. 350).
4. Substantial reconstruction or renovation making commercial occupation impossible (TBK Art. 350/2).
5. Expiration of the 10-year statutory extension period following the initial term, provided 3 months' prior written notice is served (TBK Art. 347).

Q3: Does the landlord have the right to terminate the lease if the tenant company changes its shareholders or directors?

No. The sale of shares, induction of foreign investors, or restructuring of board directorships does not alter the legal personality of the corporate tenant. The company remains the identical contractual party with the same tax identification number and rights. Changes in corporate ownership provide zero grounds for eviction or unilateral rent increases.

Q4: How can a foreign company recover its security deposit if the landlord unlawfully refuses repayment?

If the deposit was placed in a joint escrow account pursuant to TBK Article 342, the landlord cannot unilaterally withdraw the funds. Upon lease termination and formal handover, GARS serves a legal notice demanding release. If the landlord fails to initiate a formal damages lawsuit within three months of vacating, the bank is legally obligated to release the principal plus accrued interest directly to the tenant.

Q5: Can a commercial tenant sublease part of the premises to another international business?

Only if the primary lease explicitly grants subleasing rights (*Alt Kira Hakkı*) pursuant to TBK Article 322. If the contract is silent or prohibits subleasing, renting space to a third party without written consent constitutes a material breach, entitling the landlord to issue a 30-day cure notice followed by lease termination and eviction litigation.
