A letter from the Urząd Skarbowy is always stressful. Even experienced entrepreneurs think at that moment: “What’s wrong?”, “How much do I have to pay now?”, “Is this an audit?”
The good news: most of these letters are not a reason to panic, but a standard request for clarification. The tax office regularly reconciles reports, banking transactions, and data from different systems. If something doesn’t match, a letter arrives.
In this article, experts from the accounting services company Wikielson have broken down a step-by-step action plan.
What to do first?
Step 1. Read the letter carefully.
The tax office always writes specifically: the response deadline, the amount (if any), the reason for the request. Your task is to understand the type of document. It could be:
- a reminder
- a request for explanation
- a decision of the tax authority (decyzja)
- a notice of commencement of an audit
Step 2. Check the response deadline. >
You usually have 3 to 14 days. Missing it is not an option – the consequences will be worse.
Step 3. Show the letter to an accountant.
An experienced financial accountant will determine in a minute: is it a technical error in the JPK, a delay in filing a report, or a truly serious request. If you don’t have your own specialist yet – you need an accountant who understands the Polish tax system.
Step 4. Call the tax office (yes, you can do that).
One call relieves several days of anxiety. Clarify:
- whether an urgent response is really required
- whether you can ask for clarification of the wording of the request
Step 5. Prepare actions based on the situation.
Depending on the type of letter, you may need to:
- collect the requested documents
- provide a written explanation
- file a corrective declaration if an error is found
Step 6. Keep copies of everything you send.
This is important in case the tax office loses documents or disputes arise.

A letter from the tax office is not a sentence, but you cannot accumulate them
A letter from the tax office itself is not yet a problem. The problem starts when you:
- ignore the request
- miss the response deadline
- respond incorrectly without consulting a certified accountant
If many such letters accumulate, the tax office begins to see you as a “systematic violator.” Fines grow, the risk of an audit increases many times over.
When do you need an accountant?
If the wording of the letter is unclear, the requirements seem serious, or you doubt the correctness of your response, you need competent accounting and tax consultations. It is better to get accounting advice before sending a response than to fix the consequences later.
Asking an accountant a question is not a sign of weakness, but standard practice. Even large companies use outsourced accounting services to minimize risks. Remote accounting or online accounting for businesses allows you to get expert support without hiring a full-time employee.
