Přiložte účetní závěrku k daňovému přiznání.

Přiložte is the imperative form of the verb přiložit, which means to attach, to enclose, or to include as an attachment.

In this sentence, Přiložte means Attach / Enclose / Include.

The ending -te shows that it is either:

• 2nd person plural: you all attach
• or a formal singular command: please attach

So this is the normal form you would see in official instructions, forms, and business language.

For comparison:

• přilož = attach! (informal singular)
• přiložte = attach! (formal singular or plural)

Because přiložit is a perfective verb, and perfective verbs are very common in instructions when Czech wants to express a single completed action.

So Přiložte účetní závěrku... means something like:

• attach it
• make sure it is attached
• include it

If you used an imperfective form such as přikládejte, it would sound more like a repeated or ongoing action, which is not what is meant here.

In official instructions, perfective imperatives are very common because they focus on the result: the document should end up attached.

Because účetní závěrka is the direct object of the verb Přiložte. In Czech, a direct object usually goes in the accusative case.

The dictionary form is:

• účetní závěrka = accounting/financial statement

But after Přiložte it changes to accusative singular:

• účetní závěrku

This is a feminine noun, and the change from -a to -u is a very common accusative pattern for feminine nouns.

So:

• nominative: účetní závěrka
• accusative: účetní závěrku

Účetní závěrka is an accounting term. It usually means financial statements or annual accounts, even though in Czech it is grammatically singular.

So yes, it can refer to a set of financial documents treated as one accounting unit.

That is similar to how some English expressions can refer to a collection while still behaving like one item in grammar.

Because the preposition k requires the dative case.

The basic noun is:

• daňové přiznání = tax return / tax declaration

After k (to, with, attached to depending on context), it becomes dative singular:

• k daňovému přiznání

So both words change:

• daňové → daňovému
• přiznání → přiznání (same form here, but still dative)

This is very common in Czech: the preposition determines the case.

Because přiznání is a neuter noun of a type whose singular nominative and dative often look the same.

So:

• nominative: daňové přiznání
• dative: k daňovému přiznání

The noun přiznání itself stays přiznání, but the adjective changes and shows the case clearly:

• daňové → daňovému

This is one reason adjectives are very important in Czech: sometimes they make the case much easier to see.

Literally, k often means to or toward, but in this kind of official sentence it is best understood as:

• attached to
• with
• together with

So Přiložte účetní závěrku k daňovému přiznání means:

• attach the financial statements to the tax return
• enclose the financial statements with the tax return

In real usage, English may translate this in different ways depending on the style of the document.

Because Czech does not have articles like English a/an and the.

So Czech simply says:

• účetní závěrku
• daňovému přiznání

Whether English translates these as a financial statement, the financial statement, a tax return, or the tax return depends on context.

In an official instruction like this, English will often use the:

• Attach the financial statements to the tax return.

But Czech does not need a separate word for that.

No, Czech word order is fairly flexible, but this version sounds natural and neutral for an instruction:

• Přiložte účetní závěrku k daňovému přiznání.

Because Czech uses cases, the grammatical roles are clear even if the order changes. Still, different word orders can sound more marked or put emphasis on different parts.

This sentence is the most straightforward official wording.

Yes, definitely. It sounds like the language of:

• official instructions
• forms
• government communication
• accounting or tax guidance

The form Přiložte already makes it formal or plural, and the vocabulary is also administrative and technical:

• účetní závěrka
• daňové přiznání

In everyday speech, people might use less formal wording depending on the situation, but this sentence is very normal for written official Czech.

A good way to analyze it is step by step:

• Přiložte = imperative verb
• ask what should be attached?
  • účetní závěrku → direct object → accusative
• ask to what / with what should it be attached?
  • k daňovému přiznání → prepositional phrase with k → dative

So the structure is:

• verb: Přiložte
• object in accusative: účetní závěrku
• phrase with k
  • dative: k daňovému přiznání

That is a very useful pattern to practice in Czech.
