Individual tax interpretation – a PLN 40 application and legal protection

An individual tax interpretation is one of the most powerful instruments of legal protection in Polish tax law – and one of the cheapest. For PLN 40 and three months of patience you can obtain a written position of the Director of the National Tax Information Service (KIS) that protects you from tax consequences in the event of an inspection. The mechanism has worked since 2007 (the Tax Ordinance Act, Articles 14b–14q), and yet it is underrated by most small entrepreneurs.

This article shows when it is worth submitting an application, how to draft it, what to do with a negative answer and what the practical limits of the protection are.

When to apply for an interpretation

An application makes sense in three typical situations:

1. The provision is ambiguous – where several interpretations are possible (for example, the PKWiU classification for VAT purposes, the definition of “entertainment costs”, the scope of R&D activity)
2. You are planning a large investment or operation – you want to be certain of the tax effects before making a decision (for example, converting a company, using a relief, a transaction with a related party)
3. The tax authority has already challenged your position – you want to obtain a binding position for the future

Do not apply for an interpretation when the provision is unambiguous – the application will then be rejected on formal grounds (“no interpretative doubts”), or the answer will confirm the obvious for PLN 40.

What exactly an interpretation protects

The protection under Articles 14k–14m of the Tax Ordinance Act includes:

• No assessment of tax resulting from following the interpretation
• No default interest
• No fiscal-criminal penalty
• No increased (simplified) advances

Condition: the description of the factual situation in the application must match reality. If the application presents situation X and in reality it was Y, the protection does not work. That is why precision of the description is key.

How to write a good application

An application consists of several mandatory sections:

1. The applicant’s details

Name/first name and surname, NIP (tax identification number), address, correspondence details. The application can be submitted by a taxpayer, a payer or a representative (in which case a power of attorney is also needed).

2. A description of the factual situation or future event

The most important part. It must be:

• Detailed – all material facts, figures, dates
• True – you cannot slip in wishful assumptions
• Complete – you cannot leave out circumstances that could change the legal assessment
• Written in the indicative mood – “The company carries on activity…”, not “The company is planning to perhaps carry on…”

An example of how to word the start of a description (for IP Box):

The applicant has run a sole trader business since 2020, taxed under the flat tax (19%). As part of the business he creates original software for clients on a B2B basis. He works alone, with no employees. In the period from January to December 2025 he completed 12 programming projects for 4 clients, each project involving the creation of new original code from scratch. Since 1 January 2025 the applicant has kept a separate IP record in a spreadsheet…

3. The question

A specific, pinpointed question. Ideally one question per application (each additional one = an additional PLN 40). A good question:

Does the remuneration received by the Applicant for the transfer of copyright in computer programs created as part of research and development activity for B2B clients constitute qualifying income from a qualifying intellectual property right within the meaning of Article 30ca(2) point 8 of the PIT Act, entitling him to apply the 5% rate?

A bad question:

Can I use IP Box?

It is too general – the tax office may refuse to answer.

4. The applicant’s own position

Reasoned, with reference to specific provisions. “The Applicant takes the view that the answer to the question should be affirmative, because (Article X, paragraph Y of Act Z provides that…)”.

5. Signature and fee

The application is signed, and the fee is PLN 40 (for each question). A transfer to the KIS account, or an electronic payment when the application is made through ePUAP.

Deadlines and how the application is handled

The Director of KIS has 3 months from the day a complete application is received. If the application needs to be supplemented (common with incomplete descriptions), the clock stops.

What if the Director of KIS does not issue the interpretation within 3 months

A so-called “tacit interpretation” applies – the applicant’s position is deemed correct (Article 14d § 3 of the Tax Ordinance Act). It is a rare situation, but it happens – the protection then comes precisely from the lack of an answer within the deadline.

A positive interpretation – what next

After receiving a positive interpretation:

1. Keep a copy – on paper and electronic
2. Follow its content – do not improvise, do not change the factual situation
3. In an inspection – present the interpretation as evidence; the tax office must recognise it
4. If the factual situation changes – submit a new application (the existing interpretation protects only the situation described in it)

A negative interpretation – the appeal route

A negative interpretation is not a judgment. You have three options:

Option 1: A request to remedy the breach of law

Within 30 days of delivery you send the Director of KIS a request to change the interpretation. The authority has 30 days to answer. The chance of success is low (it usually upholds its position), but it is a formal requirement before a complaint to the court.

Option 2: A complaint to the WSA (the Regional Administrative Court)

After the request is rejected or there is no answer – within 30 days, a complaint to the WSA in Warsaw. The WSA often sets aside interpretations that are inconsistent with the case law.

Option 3: Accepting it

You change your business plans or follow the interpretation (at the risk that it will be costly). Without legal protection, because the interpretation is negative.

The most common mistakes of applicants

1. A description that is too general – “The company carries on business and would like to know”. The tax office will return the application.
2. A hypothetical question – “If I did X, would that be good?”. Applications on such questions are rejected – an interpretation concerns actual or planned situations, not theoretical considerations.
3. Leaving out material facts – if the interpretation was issued on an incomplete description, the protection does not work.
4. Several questions for PLN 40 – many applicants ask several questions while paying one fee. The Director of KIS has the right to consider only one question and reject the others on formal grounds.
5. A position without reasoning – “I think it should be this way”. The lack of legal argument weakens the application (it is not a formal condition, but the authority finds it easier to challenge).

When an interpretation will NOT help

• Tax proceedings are already under way – an interpretation does not stop or reverse an inspection
• Questions of evidence, not law – an interpretation does not decide whether a given expense actually happened, only how to treat it under the provisions
• General anti-avoidance clauses – an interpretation is not binding on GAAR (the anti-avoidance clause) or transfer pricing
• EU law in VAT matters – the Director of KIS must apply Polish law, but CJEU judgments (the Court of Justice of the EU) may undermine its position in the course of a complaint to the court

Summary

An individual interpretation is cheap insurance against tax risk. An application for PLN 40 gives you three months of waiting and potentially protection worth thousands. We recommend applying for an interpretation for every large operation or unusual tax situation – with the R&D relief, IP Box, Estonian CIT, transactions with related parties, and conversions. We are an accounting firm, not a tax adviser: we prepare the data from the books needed to describe the factual situation, and the application for an interpretation and representation before KIS and the administrative court are provided by a tax adviser or a lawyer (in line with the Tax Advisory Act).
