Daňový poradce vypočítá vratku daně.

Because vypočítat is a perfective verb. In Czech, perfective verbs do not normally express a true present action. Their non-past forms usually refer to a completed action in the future.

So:

• počítá = he/she calculates, is calculating, counts
• vypočítá = he/she will calculate / will work out

That is why vypočítá is understood as future here.

The prefix vy- often adds the idea of completing, working out, or producing a result.

Compare:

• počítat = to count, to calculate
• vypočítat = to calculate fully, to work out, to compute

So vypočítá suggests that the tax advisor will compute the amount/result, not just be engaged in the process of calculating.

Because vratku is the accusative singular form, and it is the direct object of the verb vypočítá.

The dictionary form is:

• vratka = refund

But after a transitive verb like vypočítat, Czech uses the accusative for the thing being calculated:

• vypočítá co? → vratku

So:

• nominative: vratka
• accusative: vratku

This is a very common pattern for feminine nouns ending in -a.

Because daně is in the genitive singular. It depends on vratka:

• vratka daně = refund of tax

This is similar to English tax refund, but Czech often expresses this relationship with the genitive:

• vratka čeho? = refund of what?
• daně

So:

• daň = tax
• daně = of tax

Yes. Daňový poradce is the subject of the sentence, so it is in the nominative singular.

You can think of the structure like this:

• Daňový poradce = subject
• vypočítá = verb
• vratku daně = object phrase

A useful detail: poradce looks unusual because it ends in -e, but it is still a masculine animate noun.

Not all masculine nouns in Czech end in a consonant. Poradce is a masculine animate noun with a special declension pattern.

Its gender is shown by agreement:

• daňový poradce
  The adjective daňový is masculine singular, which helps confirm that poradce is masculine.

This type of noun is common for professions or people, for example:

• soudce = judge
• zástupce = representative
• poradce = advisor

So the ending -e does not automatically make a noun feminine or neuter.

Daňový is an adjective meaning tax-related. It modifies poradce.

So:

• poradce = advisor
• daňový poradce = tax advisor

The adjective must agree with the noun in:

• gender
• number
• case

Since poradce is masculine singular nominative here, the adjective appears as daňový.

Czech has no articles like English a/an/the.

Whether something is understood as a tax advisor, the tax advisor, or sometimes just tax advisor depends on context.

So Daňový poradce vypočítá vratku daně could be understood in English in different ways depending on the situation, but Czech does not need a separate article word.

Yes. Czech word order is much more flexible than English because the grammatical roles are shown by case endings, not mainly by position.

The neutral order here is:

• Daňový poradce vypočítá vratku daně.

But other orders are possible, for example for emphasis:

• Vratku daně vypočítá daňový poradce.
• Daňový poradce vratku daně vypočítá.

These alternatives do not completely change the basic meaning, but they can change focus, emphasis, or what sounds most natural in a specific context.

A rough pronunciation guide is:

• daňový ≈ da-nyo-vee, with ň like the ny in canyon
• poradce ≈ po-rat-tse
• vypočítá ≈ vi-po-chee-taa
• vratku ≈ vrat-koo
• daně ≈ da-nye

A few important sounds:

• ň = a soft n sound
• č = ch in check
• c = ts
• long vowels marked by an accent, such as á and í, are held longer

So vypočítá has long í and á.

They are related but not interchangeable.

• počítá comes from počítat and usually means counts, is counting, calculates
• vypočítá comes from vypočítat and means will calculate / will work out a result

Very roughly:

• počítá focuses more on the activity or process
• vypočítá focuses more on reaching the finished result

That difference is tied to Czech verbal aspect:

• počítat = imperfective
• vypočítat = perfective

You would usually negate the verb:

• Daňový poradce nevypočítá vratku daně.

That means the tax advisor will not calculate the tax refund.

Notice:

• vypočítá → nevypočítá

The object vratku stays in the accusative here. With some verbs, negation can affect case usage, but with a sentence like this, learners will normally see the direct object stay as accusative.

The simplest way is usually intonation in speech or a question mark in writing:

• Daňový poradce vypočítá vratku daně?

You can also use a more explicitly questioning style, depending on context, but Czech often does not need a helping verb like English does.

So unlike English, you do not form the question with something like does calculate. The verb form itself stays the same.

Yes, it is a normal and understandable expression. It follows a very common Czech pattern:

• noun + genitive noun

So:

• vratka daně = refund of tax

In real-life usage, you may also encounter related financial or tax expressions depending on context, but grammatically this phrase is completely standard and useful for learners to recognize.
