Financial Advisory · Tax Litigation
Contesting an assessment
demands timing and
deliberate strategy.
The 30-day window following service of a tax and penalty notice is the period during which all legal avenues remain open. Using that window correctly means answering the right questions: settlement or litigation, which court, which arguments.
Legal Framework
VUK
Articles 370 – 392
Akbaş's Role
In tax disputes, the technical and legal dimensions are inseparable. The success of contesting an assessment depends on correctly distinguishing whether the issue stems from a declaration error or a misinterpretation by the tax authority, presenting the right evidence in time, and making the right strategic choice.
Before any proceedings begin, Akbaş prepares a report mapping the legal and technical strengths and weaknesses of your file, and provides an objective answer to the settlement-versus-litigation question. If litigation is the chosen path, we manage attorney coordination and the preparation of technical reports throughout the process.
Legal Routes
Each route carries different conditions
and different outcomes.
Multiple routes are available when contesting a tax dispute. The appropriate path must be determined according to the specific characteristics of each file.
| Route | Deadline | Decision Timeline | Tax Principal | Penalty | Advantage |
|---|---|---|---|---|---|
| Voluntary Disclosure VUK Art. 371 | Before audit begins | Immediate | Paid in full | No penalty | Zero penalty risk, fast closure |
| Pre-Assessment Settlement VUK Supp. Art. 11 | During audit phase | 15 – 30 days | May be partially reduced | Significant reduction | Resolution without litigation, low cost |
| Post-Assessment Settlement VUK Supp. Art. 1 | 30 days from notice service | 30 – 60 days | Usually in full | 50–80% reduction | Resolution without court, certainty |
| Tax Court IYK Art. 37 | 30 days from notice service | 1 – 3 years | Per court ruling | Per court ruling | Full right to contest, evidence submission |
| Regional Administrative Court Appeal | 30 days from Tax Court ruling | 1 – 2 years | Per BAM ruling | Per BAM ruling | Review of first-instance decision |
| Council of State (Danıştay) Cassation | 30 days from BAM ruling | 2 – 4 years | Per Council ruling | Per Council ruling | Legal uniformity, binding precedent |
When is settlement recommended?
- The declaration error is clear and defensible arguments are weak
- Cash flow pressure makes a fast resolution necessary
- The risk of prolonged litigation is unacceptable
- The penalty amount exceeds the principal tax (reduction-focused approach)
When is litigation recommended?
- The tax authority's misinterpretation can be technically proven
- Precedent Council of State rulings establish favourable case law
- The assessed amount is very high and settlement reduction is insufficient
- Statute of limitations or procedural errors can invalidate the assessment
Frequently Asked Questions
Common questions about
tax litigation.
How long do I have to contest a tax assessment?
You may file a case with the tax court or request settlement within 30 days of receiving the tax and penalty notice. These two options cannot be used simultaneously. The 30-day period is a lapse period; if missed, the assessment becomes final and binding.
Should I choose settlement or litigation?
Each file must be evaluated on its own merits. Settlement generally produces a faster result, incurs no litigation costs, and secures a significant penalty reduction. However, if there are strong technical arguments that the principal tax was incorrectly calculated, litigation may be more advantageous. Akbaş assesses the strengths and weaknesses of your file and provides a report recommending the appropriate path.
Is a security deposit required to file a tax court case?
Yes. To file a case with the tax court, fifty percent of the combined tax and penalty subject to the assessment must be deposited as security. This deposit is either refunded or offset against the tax debt depending on the outcome. Failure to provide the deposit may result in the case being dismissed on procedural grounds.
Can a tax court decision be appealed?
Yes. Tax court decisions may be taken to the Regional Administrative Court (BAM) by way of appeal. Where a BAM decision is not final, it may be taken to the Council of State (Danıştay) by way of cassation. Council of State decisions are final.
What is the difference between pre-assessment and post-assessment settlement?
Pre-assessment settlement is requested during the tax audit phase, before the notice is issued, and generally yields a higher reduction. Post-assessment settlement is requested within the 30-day period following service of the notice. If pre-assessment settlement breaks down, the right to request post-assessment settlement remains available.
Who can benefit from the voluntary disclosure provision?
Taxpayers who have not yet been subject to a tax audit or referred for estimation, and who voluntarily correct declaration errors that would cause a tax loss, are not subject to a tax loss penalty. Once an audit has commenced, it is no longer possible to benefit from this provision.
Did you receive a tax notice?
The 30-day window is a lapse period. Don't lose time having your file assessed for settlement vs. litigation.
