Nárok na osvobození doložíme správci poplatku.

In this sentence, doložíme means something like we will document, we will provide evidence for, or we will prove by submitting documents.

In official or administrative Czech, doložit often implies showing something with supporting paperwork, not just proving it abstractly.

So here it suggests:

• we will show evidence of the entitlement
• we will back it up with documents

Because doložíme is from the perfective verb doložit.

In Czech, perfective verbs do not normally express a true present action. Their present-tense forms usually have future meaning.

So:

• dokládáme = we are documenting / we document regularly
• doložíme = we will document / we will submit proof

That is a very common Czech pattern.

It is not stated separately, because Czech often leaves subject pronouns out when the verb ending already makes the subject clear.

The ending -me in doložíme tells you the subject is we.

So:

• doložíme = we will document

Adding my would usually only happen for emphasis:

• My doložíme... = We will document...

No. The subject is the hidden we, contained in doložíme.

Nárok is the direct object: it is the thing being documented/proven.

A useful point for learners: nárok has the same form in the nominative and accusative singular because it is a masculine inanimate noun.

So here:

• nárok = accusative singular object
• even though it looks the same as the dictionary form

Nárok often means claim, entitlement, or right in a legal or administrative sense.

In this sentence, nárok na osvobození is best understood as:

• entitlement to exemption
• or claim to exemption

In official Czech, nárok is very common when talking about whether someone legally qualifies for something.

The noun nárok commonly goes with na + accusative when it means entitlement/claim to something.

So:

• nárok na něco = entitlement to something

Here:

• na osvobození

Osvobození is in the accusative singular, but it looks the same as nominative because it is a neuter noun.

So the structure is:

• nárok na osvobození = entitlement to exemption

This is a case question.

• správci is the dative singular of správce
• poplatku is the genitive singular of poplatek

Together, správce poplatku means administrator of the fee or fee administrator.

In the sentence, správci poplatku means to the fee administrator, because that is the person to whom the proof is being submitted.

So the pattern is roughly:

• doložit něco někomu = to document/prove something to someone

It is an official term. Depending on context, it can mean something like:

• the authority administering the fee
• the office responsible for the fee
• the fee administrator/collector

Poplatek is usually a fee or charge, not a general tax. So this is administrative or legal language, not everyday conversation.

Yes, very much so.

It sounds like legal, official, or administrative Czech. A native speaker would expect this kind of sentence in:

• forms
• regulations
• instructions from an office
• official letters

In more everyday Czech, someone might say the same idea less formally, for example by using a fuller clause such as that we are entitled to exemption rather than the compact noun phrase nárok na osvobození.

Czech word order is flexible, and this order puts nárok na osvobození first for emphasis or as the topic of the sentence.

A more neutral English-style order might feel like:

• Doložíme správci poplatku nárok na osvobození.

Both are grammatical, but the original sounds natural in official style, where the important legal item is often placed first.

So the original order highlights:

• the entitlement to exemption as the key thing under discussion
