Chci uplatnit daňový odpočet a slevu na dani.

Yes. Chci means I want.

It is the 1st person singular form of the verb chtít (to want).

• já chci = I want
• In Czech, the subject pronoun já is often omitted because the verb ending already shows who is doing the action.

So:

• Chci uplatnit... = I want to claim/apply...

Using Já chci... is possible, but it usually adds emphasis, like I want to.

Because Czech uses the infinitive after verbs like chtít (to want), just like English often uses to + verb.

So:

• chci uplatnit = I want to claim/apply
• literally: I want claim

This pattern is very common:

• Chci jít. = I want to go.
• Chci pracovat. = I want to work.
• Chci uplatnit odpočet. = I want to claim a deduction.

In this context, uplatnit means something like:

• to claim
• to apply
• to make use of officially

It is often used for legal, financial, and administrative things, for example:

• uplatnit nárok = to claim an entitlement
• uplatnit slevu = to claim a discount / tax relief
• uplatnit reklamaci = to file or make a complaint/warranty claim

So in this sentence, uplatnit means to claim a tax deduction and a tax allowance/credit.

Because they are two different fixed ways of expressing tax relief in Czech.

1. daňový odpočet

   • literally tax deduction
   • daňový is an adjective meaning tax-related
   • odpočet means deduction

2. sleva na dani

   • literally discount/relief on tax
   • sleva means discount / reduction / relief
   • na dani means on tax

So although both relate to lowering tax, Czech expresses them differently.

This is very natural and standard Czech, especially in financial/tax language.

They are not the same thing, even though both reduce what you pay.

Very roughly:

• odpočet = deduction
  • something is deducted from the tax base or taxable amount
• sleva na dani = tax credit / tax relief / tax allowance
  • something directly reduces the tax itself

The exact legal meaning depends on the tax system and context, but for a learner the important point is:

• odpočet and sleva are two different tax terms
• they are not interchangeable

Because slevu is the accusative singular form of sleva.

The verb uplatnit takes a direct object, and direct objects are usually in the accusative.

So:

• sleva = nominative
• slevu = accusative

Compare:

• To je sleva. = That is a discount/relief.
• Chci uplatnit slevu. = I want to claim the discount/relief.

The same thing is happening with odpočet, except that for this noun the nominative and accusative look the same:

• odpočet = nominative
• odpočet = accusative

Dani is the locative singular of daň (tax).

It appears because of the preposition na, which here means something like on or with regard to.

So:

• sleva na dani = literally relief on tax
• dani is in the locative because na often requires the locative when it means location or an abstract relation like this.

Forms of daň:

• nominative: daň
• genitive: daně
• dative: dani
• accusative: daň
• locative: dani
• instrumental: daní

In this phrase, you should learn sleva na dani as a set expression.

They come from the same noun, daň (tax), but they are different grammatical forms.

• daňový = adjective meaning tax-related
• dani = a case form of the noun daň

So:

• daňový odpočet = tax deduction
• sleva na dani = relief on tax

English often uses tax in a very flexible way, but Czech may switch between:

• a noun form: daň, dani
• an adjective form: daňový

That is normal.

Because Czech has no articles.

English says:

• a tax deduction
• the tax deduction

Czech simply says:

• daňový odpočet

Whether it means a or the depends on context.

So in this sentence:

• daňový odpočet could correspond to a tax deduction or the tax deduction
• slevu na dani could correspond to a tax credit/relief or the tax credit/relief

The given word order is natural and neutral:

• Chci uplatnit daňový odpočet a slevu na dani.

But Czech word order is more flexible than English, especially if you want to change emphasis.

For example, you might also hear:

• Daňový odpočet a slevu na dani chci uplatnit.

This puts more focus on what you want to claim.

Still, for a learner, the original version is the best standard word order to use.

Uplatnit is perfective.

That means it presents the action as a complete act: to claim/apply successfully as a whole.

The imperfective partner is usually uplatňovat.

Very roughly:

• uplatnit = to claim / apply as a completed action
• uplatňovat = to be claiming / to claim repeatedly / to be in the process of applying

In this sentence, uplatnit is the natural choice because the speaker wants to perform the action as a concrete complete step.

A simple approximate pronunciation is:

Kh-tsee oop-lat-nit da-nyo-vee ot-po-chet a sleh-voo na da-nyee

A few useful notes:

• ch in chci is like the ch in German Bach or Scottish loch
• c is pronounced ts
• č is pronounced ch as in church
• ň is a soft n
• stress in Czech is usually on the first syllable of each word:
  • CHCI
  • Uplatnit
  • DAŇový
  • ODpočet
  • SLEvu
  • NA dani

Literally, yes, because sleva often means discount. But in this context, that translation may sound too everyday or too vague in English.

In tax language, better translations are usually:

• tax relief
• tax credit
• tax allowance

The best translation depends on the legal context. So while discount on tax helps you understand the structure, it is usually not the best final English translation.

Yes. A means and.

So:

• daňový odpočet a slevu na dani = a tax deduction and a tax relief/credit

It simply joins the two objects of uplatnit.

Notice that both things joined by a are objects of the same verb:

• claim a deduction
• claim a tax relief
