La tassa di soggiorno è inclusa nel conto.

Tassa di soggiorno is the tourist tax or city tax that guests may have to pay when staying in a hotel, apartment, or other accommodation.

Literally:

• tassa = tax
• soggiorno = stay, lodging, period of staying somewhere

So the phrase means tax for the stay.

In Italian, di is often used to link two nouns, where English might use:

• of
• a noun used like an adjective
• a compound noun

So:

• tassa di soggiorno = tax of stay = stay tax / tourist tax

This structure is very common in Italian:

• camera da letto = bedroom
• bicchiere di vino = glass of wine
• ufficio postale = post office

Here, di soggiorno specifies what kind of tax it is.

La is the feminine singular definite article, meaning the.

It is used because tassa is:

• singular
• feminine

So:

• la tassa = the tax

In dictionaries, nouns are usually learned with their gender:

• la tassa
• il conto
• il soggiorno

Because inclusa agrees with la tassa, which is feminine singular.

In Italian, past participles used like adjectives must agree in gender and number with the noun they describe.

So:

• la tassa è inclusa = the tax is included
• il servizio è incluso = the service is included
• le tasse sono incluse = the taxes are included
• i pasti sono inclusi = the meals are included

The ending changes to match the noun:

• -o = masculine singular
• -a = feminine singular
• -i = masculine plural
• -e = feminine plural

It comes from the verb includere (to include), but in this sentence it functions as a past participle with essere, giving the meaning is included.

So:

• è inclusa = is included

You can think of it as similar to English:

• The tax is included

Italian often uses this structure:

• Il prezzo è indicato = The price is indicated
• La colazione è compresa = Breakfast is included

Nel means in the.

It is a contraction of:

• in + il = nel

So:

• nel conto = in the bill / in the total / on the bill

This kind of contraction is very common in Italian:

• in + il = nel
• in + lo = nello
• in + la = nella
• in + i = nei
• in + gli = negli
• in + le = nelle

Because conto here is a specific noun with the definite article: il conto.

When in is followed by il, they normally combine:

• in il conto → nel conto

So the full idea is included in the bill or included in the total.

Without the article, the meaning would usually change or sound unnatural in this sentence.

Here, conto means bill, check, or total amount to be paid.

Even though conto can have other meanings in different contexts, in restaurants, hotels, and travel situations it often means:

• the bill
• the final amount
• the charge

Examples:

• Il conto, per favore. = The bill, please.
• È incluso nel conto. = It is included in the bill.

This is very important:

• è with an accent = is
• e without an accent = and

So in your sentence:

• è inclusa = is included

Compare:

• La tassa è inclusa. = The tax is included.
• La tassa e il servizio... = The tax and the service...

The accent matters because it changes the meaning completely.

Yes. Compresa is very common in this context.

So:

• La tassa di soggiorno è inclusa nel conto.
• La tassa di soggiorno è compresa nel conto.

Both mean that the tax is included in the bill/price. In everyday hotel or booking language, incluso/a and compreso/a are both widely used.

You may also see:

• tassa di soggiorno inclusa
• tassa di soggiorno compresa

Yes, Italian word order is fairly flexible, though the original sentence is the most neutral and straightforward.

Possible variations:

• La tassa di soggiorno è inclusa nel conto. = neutral, standard
• Nel conto è inclusa la tassa di soggiorno. = emphasizes in the bill
• La tassa di soggiorno nel conto è inclusa. = possible in special contexts, but less natural

For a learner, the best version to use is:

• La tassa di soggiorno è inclusa nel conto.

You would change the article, noun, verb, and participle as needed.

For example:

• Le tasse di soggiorno sono incluse nel conto. = The tourist taxes are included in the bill.

Changes:

• la → le
• tassa → tasse
• è → sono
• inclusa → incluse

This shows how much agreement matters in Italian.
