Legal Events Giving Rise to Tax Liability: A Study of Taxable Events with Practical Examples

Introduction: The Fine Line Between "Taxable Event" and "Tax Liability"

A tax liability legally comes into existence upon the occurrence of the event giving rise to the tax liability . In Turkish tax law, this framework is defined by the principle of legality in Article 73 of the Constitution and the typicality provisions of tax laws (Tax Procedure Law, Income Tax Law, Corporate Tax Law, Value Added Tax Law, Special Consumption Tax Law, Stamp Duty Law, Fees Law, Motor Vehicle Tax Law, Real Estate Tax Law, Inheritance and Transfer Tax Law, etc.) . The rule is simple: the tax liability arises the moment the event linked to tax by law occurs. Even if the invoice is issued late, the payment is made later, or the parties agree on different dates, the legal event is the determining factor.

This article offers practical reading by classifying the legal events that give rise to tax liability according to their types and illustrating them with case examples from practice

1) Typology of Legal Events: Factual Event – ​​Legal Transaction – Legal Situation – Administrative/Judicial Action

We can categorize tax-related events into four main groups:

1. Material event: Actual occurrences such as delivery, performance of services, import, manufacturing/initial acquisition (typical for VAT/Special Consumption Tax).

2. Legal transaction: Declarations of intent such as contracts, undertakings, and power of attorney (typical for stamp duty and fees).

3. Legal status: Statuses such as ownership or possession (typical for Motor Vehicle Tax and Property Tax).

4. Administrative/judicial procedures: Registration, licensing, court rulings, notarial transactions (including fees and stamp duty).

Tax liability arises to the extent that tax laws explicitly typify the event ; the administration's expansive interpretation is limited by the prohibition of analogy.

2) Income and Corporate Tax: The Tax Threshold of "Income/Profit Earning"

2.1. Wages, Freelance Work, Commercial Income (GVK)

• Legal event: Earning of income (based on collection or accrual).

• Example 1 (wage): The employer prepared the payroll and paid the wage on the 5th of the following month. Income is considered to have arisen upon accrual of the wage ; tax arises at source through withholding (stopaj)

• Example 2 (self-employment): Legal services completed, receipt issued at the time of service . The taxable event occurs with the earning/collection of income ; if withholding tax is applicable (Article 94 of the Income Tax Law), a portion of the tax liability arises from the withholding tax

• Example 3 (commercial profit): Goods were sold, invoices were issued within 7 days; payment was received 60 days later. Profit accrual basis; VAT is due delivery .

2.2. Corporate Tax (KVK)

• Legal event: The formation of corporate income at the end of the period (accrual basis).

• Example: A company has determined its year-end profit. Corporate tax liability arises upon the receipt of profit ; provisional tax periods are interim periods that are offset against the final tax .

2.3. Income from Securities and Dividends

• Legal event: Distribution of dividends and their receipt by the rightful owner .

• Example: Dividends were distributed on May 20th by a general assembly decision, and the investor received them in their account on May 25th. Tax liability arises of receipt ; withholding tax (stopaj) at source .

2.4. Rental Income (GMSI)

• Legal event: Receipt of rent .

• Example: A landlord who leases a business premises to a company receives the rent monthly. The company pays the rent through withholding tax . The tax liability arises from the withholding tax ; it is offset during the annual declaration period .

3) VAT: The “Actual” Realization of Delivery and Service is Key

3.1. Delivery of Goods and Provision of Services

• Legal event: Delivery (transfer of possession of the goods to the buyer) or performance of a service.

• Example 1 (delivery): The e-commerce company shipped the product on April 3rd, and the buyer received it on April 5th. The taxable event of delivery ; even though the invoice is issued on April 7th, the debt delivery .

• Example 2 (service): Consulting services were completed on June 15th; advances had been collected previously. As a rule, the taxable event is the performance of the service; advances may give rise to VAT earlier (except for legal exemptions and special circumstances).

3.2. Import – Export Registered Delivery – Partial Withholding Tax

• Import: of goods through customs triggers VAT; the tax liability arises at customs.

• Export-registered delivery: The tax accrues upon delivery; the deferral-cancellation mechanism ensures the transportation of the goods.

• Partial withholding: In certain services (construction-contracting, labor supply, etc.), the buyer the VAT ; the VAT liability on both sides (seller's declaration + buyer's withholding).

---

4) Special Consumption Tax (ÖTV): Manufacturing, Importing or First Acquisition “Typical Event”

• Legal event: Manufacturing , importing , or initial acquisition of goods listed by law .

• Example 1 (motor vehicle): The Special Consumption Tax (SCT) liability arises with the initial acquisition upon the distributor's first sale ; the dealer-end consumer chain comes later.

• Example 2 (fuel/alcoholic beverages): Tax liability arises immediately upon withdrawal from production or import ; it is related to the tax stamp and tracking system.

---

5) Stamp Duty and Fees: Legal Transaction as a "Contract/Transaction"

5.1. Stamp Duty (on Paper)

• Legal event: Preparation/signing of taxable documents (including electronic).

• Example 1: A 24-month office lease agreement has been signed. Stamp duty liability arises upon the issuance of the document; subsequent changes to the price often affect the tax base

• Example 2: The tender contract and the guarantee letter were issued on the same day. Separate stamp duty may be levied for both documents (exceptions apply).

5.2. Fees (Judicial – Notary – Land Registry – Passport etc.)

• Legal event: The act of performing a transaction or making an application.

• Example 1 (court fees): The filing fee arises the moment the lawsuit petition is registered via UYAP ; court fees for judgments and decrees arise based on the outcome .

• Example 2 (land registry fee): It is the sale and registration process , not the promise to sell real estate , that gives rise to a fee; under-declaration of the price may be subject to ex officio assessment.

6) Motor Vehicle Tax, Property Tax, and Vehicle Tax: Legal Situations Based on "Ownership and Registration"

6.1. Motor Vehicle Tax (MTV)

• Legal event: Ownership at the beginning of the taxation period, along with the registration and titling of the vehicle

• Example: You purchased and registered the vehicle on July 10th. The debt for that period belongs to whoever was the taxpayer at the beginning of the period; proportional sharing is subject to special rules.

6.2. Property Tax

• Legal event: Acquisition of ownership of the immovable property (the new building becoming ready for use is also of importance).

• Example: Construction is complete; occupancy permit has been obtained. Property tax accrues upon ownership , subject to any exemptions/discounts for the first year .

6.3. Environmental Cleaning Tax (ECT)

• Legal issue: Use of services provided by municipalities ; debt is accrued based on water consumption in workplaces (in practice collected via water bill).

---

7) Inheritance and Transfer Tax: “Opening of Inheritance” and “Gratuitous Transfer”

• Legal events: Opening of inheritance upon death ; gratuitous transfers such as gifts

• Example 1 (inheritance): The testator passed away on March 12th. The tax liability on that date ; the declaration and installment schedule in the law .

• Example 2 (donation): The transfer of company shares was made through a donation. the gratuitous transfer ; the VAT aspect of the commercial transaction is evaluated separately.

---

8) Bank and Insurance Transactions Tax (BSMV) – Special Communication Tax (ÖİV)

• BSMV legal event: Transactions made by a bank/insurance company and the monies received as a result of these transactions .

  • Example: A BSMV (Banking and Insurance Transactions Tax) liability arises when a bank charges a loan origination fee.

• The legal event related to private communication services: Provision of communication services .

  • Example: The GSM operator's monthly service bill; the Special Consumption Tax (ÖİV) liability arises upon the provision of the service

9) E-Processes and Digital Documents: Does the Situation Change When It Becomes "Electronic"?

Digital tools such as e-invoicing, e-archiving, e-contracts, and e-notifications do not change the nature of the event; they only proof and procedure .

• Stamp duty is due when the contract is signed (exceptions and rates reserved).

• Issuing an e-invoice late does not change the delivery/service time for VAT purposes; it only creates a specific risk of irregularity.

• Notification of tax assessment via e-notification initiates the deadlines ; allegations of irregularities can be critical for deadline management.

---

10) Common Mistake Points in Practice (Lawyer Checklist)

• The time of delivery/service is being incorrectly determined: The VAT liability arises earlier than expected

• Contract annexes are being overlooked: In stamp duty, additional protocols can also give rise to tax liabilities.

• Property transfers are getting confused with registration: Delays in land registry registration lead to shifts in tax liabilities for property tax and motor vehicle tax .

• Withholding tax is being ignored: It is forgotten that a debt arises at source in payments that should be subject to withholding tax .

• The import-customs stage is being overlooked: VAT/excise tax debt at customs ; subsequent correction is difficult.

• Electronic records: the e-invoice/e-archive timestamp and shipping/delivery records are inconsistent.
