Sazba poplatku je důležitá pro správce poplatku.

Because sazba poplatku means the rate of the fee/charge, and in Czech that of the fee relationship is usually expressed with the genitive case.

• poplatek = fee, charge
• poplatku = of the fee

So:

• sazba = rate
• sazba poplatku = rate of the fee

This is very common in Czech. Compare:

• cena výrobku = the price of the product
• název knihy = the title of the book
• správce poplatku = administrator of the fee / fee administrator

Sazba usually means rate, tariff, or set amount/level used for calculating something.

In this sentence, sazba poplatku is not just a fee, but more specifically the fee rate or the rate/amount of the charge.

Depending on context, English could translate it as:

• the fee rate
• the charge rate
• the amount of the fee

So sazba is a formal or administrative word often used in legal, financial, or official contexts.

Because důležitá has to agree with sazba, and sazba is:

• feminine
• singular

So the adjective must also be feminine singular:

• důležitý = masculine singular
• důležitá = feminine singular
• důležité = neuter singular or plural in some contexts

Here the subject is sazba poplatku, and the head noun is sazba, so the correct form is:

• Sazba ... je důležitá.

After pro, Czech uses the accusative case.

So in pro správce poplatku, správce is accusative.

The reason it looks the same as the basic dictionary form is that správce belongs to a noun pattern where:

• nominative singular = správce
• accusative singular = správce

So even though the case changes, the form does not.

Breakdown:

• správce = administrator, manager
• pro správce = for the administrator

This is normal for some masculine animate nouns ending in -ce, such as words following the soudce pattern.

Yes, Czech could sometimes avoid repetition, but repeating the noun is very normal, especially in formal or administrative language.

Here:

• sazba poplatku = the fee rate
• správce poplatku = the fee administrator / administrator of the fee

Using poplatku twice makes the sentence precise and official-sounding. Czech often prefers that kind of clarity in formal style.

A pronoun would usually sound less natural or less precise here.

So the repetition is not bad style in this context; it is quite typical.

In normal standard Czech, you usually must keep je in sentences like this.

So:

• Sazba poplatku je důležitá... = correct
• Sazba poplatku důležitá... = not normal standard Czech

Czech does not usually omit the present tense of být (to be) in ordinary sentences with predicate adjectives.

So unlike some Slavic languages, Czech normally says:

• On je unavený. = He is tired.
• To je pravda. = That is true.
• Sazba poplatku je důležitá. = The fee rate is important.

Pro usually means for.

In this sentence:

• pro správce poplatku = for the fee administrator

It shows for whom something is important.

So the structure is:

• X je důležité pro Y = X is important for Y

Examples:

• To je důležité pro studenty. = That is important for students.
• Tato informace je důležitá pro učitele. = This information is important for teachers.

The word order is not completely fixed. Czech is more flexible than English because case endings show the grammatical relationships.

The original sentence:

• Sazba poplatku je důležitá pro správce poplatku.

A different but still natural version could be:

• Pro správce poplatku je sazba poplatku důležitá.

Both mean essentially the same thing, but the emphasis changes a little:

• starting with Sazba poplatku focuses first on the fee rate
• starting with Pro správce poplatku focuses first on for the administrator

So the original order is normal, but not the only possibility.

Yes, literally that is exactly what it is.

• správce = administrator, manager
• poplatku = of the fee

So správce poplatku literally means administrator of the fee.

In better English, depending on context, that might be rendered as:

• fee administrator
• administrator responsible for the fee
• collector/administrator of the charge

Czech official language often uses noun + genitive structures like this.

You can tell from both meaning and agreement.

The verb is:

• je = is

The adjective is:

• důležitá = important, feminine singular

That adjective agrees with sazba, which is feminine singular. So sazba poplatku is the thing being described as important.

Meanwhile, pro správce poplatku is a prepositional phrase meaning for the fee administrator, not the subject.

So the sentence structure is:

• Subject: Sazba poplatku
• Verb: je
• Predicate adjective: důležitá
• Prepositional phrase: pro správce poplatku

Yes, it sounds fairly formal and administrative.

Words like these make it sound official:

• sazba
• poplatek
• správce

This is the kind of sentence you might see in:

• legal texts
• tax or fee regulations
• administrative documents
• official instructions

In everyday conversation, people might phrase things more simply, depending on the context. But as a model of formal Czech, this sentence is very natural.
