Corporate Tax Provision & Deferred Tax in Turkey: A CFO Guide
A Turkish corporate tax return and an IFRS income-tax provision answer different questions. The tax return determines the company’s current tax position under Turkish tax law. IAS 12 reporting requires the finance team to go further: reconcile accounting profit to taxable profit, identify temporary differences, assess tax losses and credits, calculate deferred tax and explain the effective tax rate to headquarters.
For a Turkish subsidiary, the income-tax provision should usually be built in two layers. First, calculate current tax using the Turkish taxable profit and the tax rates applicable to the company and its qualifying income. Second, calculate deferred tax under IAS 12 by comparing the carrying amounts of assets and liabilities with their tax bases and recognising the tax effect of temporary differences, unused tax losses and credits where the recognition criteria are met. The final group reporting pack should reconcile the statutory tax calculation, deferred-tax movements and the effective tax rate.
Current Tax and Deferred Tax Are Different
IAS 12 distinguishes between current tax and deferred tax. Current tax is based on taxable profit for the period. Deferred tax reflects future tax consequences arising from differences between the accounting carrying amount of an asset or liability and its tax base, together with certain unused tax losses and credits.
Current tax
- Starts from Turkish taxable profit.
- Uses enacted or substantively enacted tax rules and rates.
- Reflects deductions, exemptions, disallowable expenses and applicable rate reductions.
- Creates a current tax payable or receivable.
Deferred tax
- Starts from balance-sheet differences.
- Compares accounting carrying amounts with tax bases.
- Recognises taxable and deductible temporary differences subject to IAS 12 rules.
- Creates deferred tax assets or liabilities.
Corporate Tax Rates in Turkey for 2026
For 2026, the general Turkish corporate income tax rate is 25%. A 30% rate applies to specified financial-sector companies and certain other entities covered by Article 32 of the Corporate Tax Law. Turkish law also contains reduced-rate mechanisms for qualifying income, including export and manufacturing activities, subject to the statutory conditions.
| Category | 2026 rate / treatment | Provision impact |
|---|---|---|
| General corporate taxpayers | 25% | Headline rate for ordinary taxable profit unless another specific rule applies. |
| Specified financial-sector and other covered entities | 30% | Different current and deferred tax rate may be relevant depending on the entity. |
| Qualifying export income | General rate reduced by 5 percentage points for qualifying income. | Requires income segregation and assessment of the rate expected to apply. |
| Qualifying manufacturing income | General rate reduced by 1 percentage point for qualifying income. | Requires support for the income benefiting from the reduced rate. |
| Domestic minimum corporate tax | 10% minimum calculation under Article 32/C, subject to the statutory base and exceptions. | Can affect the expected current tax charge even where exemptions or deductions reduce ordinary CIT. |
The rate used for deferred tax is not simply a mechanical “always 25%” assumption. IAS 12 requires measurement using the tax rates expected to apply when the asset is realised or the liability settled, based on rates and tax laws enacted or substantively enacted at the reporting date.
How to Build the Current Tax Provision
A group reporting tax provision should start from accounting profit and reconcile to Turkish taxable profit. The tax-return computation remains the legal tax calculation, but the monthly or quarterly provision process should explain the bridge before year-end.
+ non-deductible expenses
− exempt income
± tax-specific adjustments
− tax losses utilised, where available
= taxable profit / tax loss
× applicable corporate tax rate(s)
± minimum tax / other applicable tax effects
= current tax before prepayments and credits
The exact bridge depends on the company, but recurring items may include:
- Non-deductible expenses under Turkish tax rules.
- Tax-exempt income or qualifying participation / disposal exemptions where conditions are met.
- Differences between accounting depreciation and tax depreciation.
- Provisions or accruals recognised for accounting but deductible for tax in a different period.
- Foreign-exchange or valuation differences.
- Prior-year tax losses available for utilisation, subject to the applicable rules.
- Investment incentive or rate-reduction effects.
- Export / manufacturing reduced-rate calculations.
- Domestic minimum corporate tax.
Domestic Minimum Corporate Tax: Why It Matters for Provisioning
Türkiye introduced a domestic minimum corporate tax regime effective for 2025 and subsequent periods. Under Article 32/C, the corporate tax calculated under the ordinary rules cannot fall below the prescribed minimum calculation based broadly on 10% of the relevant pre-deduction corporate income base, after taking into account the statutory exclusions and adjustments.
This means a company may calculate a relatively low ordinary corporate tax amount because of exemptions or deductions but still have a higher current tax liability under the domestic minimum-tax mechanism.
For tax provisioning, the finance team should therefore model at least two calculations:
- Ordinary Turkish corporate tax under the company’s applicable rates, exemptions and deductions.
- Domestic minimum corporate tax under Article 32/C.
The expected current tax expense should reflect the higher payable amount where the minimum-tax calculation applies.
What Is a Temporary Difference?
IAS 12 defines temporary differences by comparing the carrying amount of an asset or liability in the financial statements with its tax base. The difference can be taxable or deductible.
| Type | Economic effect | Typical result |
|---|---|---|
| Taxable temporary difference | Future recovery or settlement is expected to create additional taxable amounts. | Deferred tax liability, subject to IAS 12 exceptions. |
| Deductible temporary difference | Future recovery or settlement is expected to create future tax deductions. | Deferred tax asset, subject to recognition criteria. |
The key distinction is between temporary and permanent differences. A permanent difference affects the effective tax rate but does not reverse in a future period and therefore does not create deferred tax.
Common Deferred-Tax Areas for Turkish Subsidiaries
| Area | Why a temporary difference may arise | Typical tax accounting outcome |
|---|---|---|
| Fixed assets | Accounting carrying amount and tax written-down value differ because of depreciation methods, useful lives or reporting adjustments. | Deferred tax asset or liability depending on the direction of the difference. |
| Provisions | An accounting provision may not be deductible for Turkish tax until a later event or payment. | Potential deferred tax asset if future deduction is expected and recognition criteria are met. |
| Accrued expenses | Expense recognised in accounting before tax deduction is available. | Potential deductible temporary difference. |
| Leases | IFRS 16 right-of-use assets and lease liabilities may not align with the local tax base. | Deferred-tax effects may arise from the asset and liability positions. |
| Employee benefits | Accounting recognition and tax deductibility may occur in different periods. | Potential deferred tax asset. |
| Receivable impairment | Accounting impairment may precede satisfaction of Turkish tax deductibility conditions. | Potential deferred tax asset. |
| Inventory / provisions | Accounting write-downs may not be immediately deductible for tax. | Potential deductible temporary difference. |
| Foreign currency / functional currency effects | Accounting and tax bases may move differently. | Deferred tax may arise depending on the reporting architecture. |
| IFRS / TFRS adjustments | Group reporting entries change carrying amounts without changing the Turkish tax base. | Creates or changes temporary differences. |
| Inflation accounting | Tax inflation adjustment and financial-reporting inflation accounting may not produce identical carrying amounts or tax bases. | Potentially significant deferred-tax movements. |
Deferred Tax on Tax Losses
IAS 12 permits recognition of a deferred tax asset for unused tax losses and unused tax credits when the recognition criteria are satisfied. The central question is recoverability: is it probable that sufficient future taxable profit will be available against which the losses or credits can be utilised?
For a Turkish subsidiary, a recoverability assessment should not be a generic statement that “the company expects to be profitable.” A stronger file can include:
- Tax-loss schedule by year.
- Legal expiry / utilisation period under Turkish tax rules.
- Approved budgets and forecasts.
- Reconciliation of forecast accounting profit to forecast taxable profit.
- Expected utilisation of incentives and exemptions.
- Impact of domestic minimum corporate tax.
- Evidence supporting the group’s assumptions.
Effective Tax Rate Reconciliation
The effective tax rate, or ETR, explains why the group’s total tax expense differs from simply multiplying accounting profit before tax by the headline corporate tax rate.
Common ETR reconciling items for a Turkish subsidiary may include:
- Non-deductible expenses.
- Tax-exempt income.
- Reduced corporate tax rates for qualifying activities.
- Domestic minimum corporate tax.
- Unrecognised deferred tax assets.
- Changes in recognition of tax losses.
- Prior-period current tax adjustments.
- Changes in enacted tax rates.
- Permanent differences arising from group-reporting adjustments.
- Uncertain tax positions.
A well-designed ETR bridge is often one of the fastest ways for headquarters to understand why the Turkish entity’s tax charge moved from one period to another.
A Practical Tax Provision Process
Close the accounting period
Complete the Turkish month-end close and ensure the trial balance is reconciled before building the tax provision.
Prepare the current tax bridge
Reconcile accounting profit to taxable profit and identify the tax rates, exemptions, deductions and minimum-tax rules relevant to the entity.
Update tax bases
Maintain a balance-sheet tax-base schedule for material assets and liabilities.
Calculate temporary differences
Compare each material carrying amount with its tax base and classify the resulting taxable or deductible temporary difference.
Assess tax losses and credits
Update the carryforward schedule and determine whether the recognition criteria for deferred-tax assets are met.
Apply the appropriate tax rate
Use the rate expected to apply when the temporary difference reverses, based on enacted or substantively enacted law.
Prepare the ETR reconciliation
Explain the difference between the headline rate and the total tax expense recognised in the reporting pack.
Reconcile to the general ledger
Tie current tax payable, prepaid tax, deferred tax assets / liabilities and tax expense back to the reporting ledger.
Tax Provision Should Connect to the Month-End Close
A tax provision prepared from an unreconciled trial balance is inherently unstable. Tax accounting therefore depends on the same close controls as management reporting: reconciled banks, payroll, tax accounts, fixed assets, intercompany and accruals.
For recurring group reporting, it is usually better to build the tax provision into the month-end or quarter-end close rather than wait until the annual corporate tax return.
Current Tax Payable vs Prepaid / Advance Tax
The current tax provision is not necessarily equal to the cash tax still payable at the reporting date. Turkish corporate taxpayers may have advance / provisional tax payments, withholding credits or other tax prepayments that reduce the net current tax payable.
A clean tax balance-sheet reconciliation should distinguish:
- Gross current tax provision.
- Advance corporate tax / provisional tax paid or accrued.
- Withholding credits where applicable.
- Prior-year current tax balances.
- Tax receivables / refunds.
- Net current tax payable or receivable.
Uncertain Tax Positions and IFRIC 23
IFRIC 23 applies when there is uncertainty about whether the tax authority will accept a tax treatment. This can affect current tax, deferred tax or both.
For a Turkish subsidiary, uncertainty may arise around areas such as:
- Deductibility of material expenses.
- Cross-border service charges.
- Transfer-pricing positions.
- Withholding-tax classification.
- Qualification for an exemption or incentive.
- Tax-loss utilisation.
IFRIC 23 requires the entity to assess whether it is probable that the tax authority will accept the treatment. If not, the effect of uncertainty is reflected using the method that better predicts the resolution, such as the most likely amount or expected value.
Pillar Two: Separate the Global Minimum Tax Layer
IAS 12 contains a temporary exception from recognising and disclosing deferred tax assets and liabilities arising from the implementation of OECD Pillar Two model rules. Affected multinational groups nevertheless have separate current-tax and disclosure considerations under the Pillar Two amendments.
Türkiye has implemented global and domestic minimum top-up tax rules. For groups within scope, the Turkish finance team should therefore distinguish:
- Ordinary Turkish corporate income tax.
- Domestic minimum corporate tax under Turkish corporate tax law.
- Pillar Two / qualified domestic minimum top-up tax calculations.
- IAS 12 current-tax and disclosure implications for the group.
These are related tax layers but they should not be collapsed into one calculation.
Deferred Tax and Inflation Accounting
Inflation accounting can create significant tax-accounting complexity because the carrying amounts used for financial reporting and the tax bases used for Turkish tax purposes may move differently.
The finance team should maintain a clear bridge showing:
- Accounting carrying amount after the applicable financial-reporting inflation adjustment.
- Tax base after the applicable Turkish tax treatment.
- Resulting temporary difference.
- Tax rate applied to the expected reversal.
- Deferred-tax movement recognised in the group reporting period.
This is another reason why deferred tax should be calculated from a controlled balance-sheet schedule rather than as a top-side percentage of the current tax computation.

Frequently Asked Questions
What is the corporate tax rate in Turkey in 2026?
The general corporate income tax rate is 25% for ordinary corporate taxpayers. A 30% rate applies to specified financial-sector companies and certain other entities covered by the Turkish Corporate Tax Law. Reduced rates may apply to qualifying export and manufacturing income subject to the statutory conditions.
What is deferred tax under IAS 12?
Deferred tax represents future tax consequences arising mainly from temporary differences between the carrying amounts of assets and liabilities in the financial statements and their tax bases, together with qualifying unused tax losses and credits.
What is the difference between current tax and deferred tax?
Current tax is based on taxable profit for the current or prior periods. Deferred tax reflects the future tax effect of existing balance-sheet differences and certain losses or credits.
Does Turkey have a minimum corporate tax?
Yes. Türkiye introduced a domestic minimum corporate tax regime effective from 2025. The calculation is based on Article 32/C of the Corporate Tax Law and can cause the tax payable to exceed the amount calculated under the ordinary exemption and deduction framework.
Can tax losses create a deferred tax asset?
Potentially yes. IAS 12 permits a deferred tax asset for unused tax losses when the recognition criteria are satisfied, including the probability of sufficient future taxable profit against which the losses can be utilised.
What are common deferred-tax items in Turkey?
Common items can include fixed assets, provisions, accruals, leases, employee benefits, doubtful receivables, inventory adjustments, foreign-currency differences, inflation-accounting differences and other IFRS or group-reporting adjustments.
Should the deferred-tax rate always be 25%?
No. IAS 12 requires deferred tax to be measured using the rate expected to apply when the asset is realised or liability settled, based on enacted or substantively enacted tax law. The appropriate rate may differ depending on the entity and the expected reversal of the underlying temporary difference.
What is an effective tax rate reconciliation?
An ETR reconciliation explains why total tax expense differs from the amount obtained by multiplying accounting profit before tax by the headline corporate tax rate. It identifies permanent differences, reduced rates, unrecognised tax losses, minimum tax and other reconciling items.
How does IFRIC 23 affect Turkish tax reporting?
IFRIC 23 applies where there is uncertainty about whether the tax authority will accept a tax treatment. The company must assess the uncertainty and reflect it in current tax or deferred tax where required under the interpretation.
Can SystemsCPA prepare the Turkish tax provision for group reporting?
Yes. Depending on scope, SystemsCPA can support the current tax computation, deferred-tax schedules, tax-loss analysis, effective tax-rate reconciliation, tax balance-sheet tie-out and reporting package required by headquarters.
