Kostnadsstedet står i reiseregningen uavhengig av om bompengene øker.

Because kostnadssted is a neuter noun in Norwegian, and -et is the definite singular ending for many neuter nouns.

• et kostnadssted = a cost center / cost code
• kostnadsstedet = the cost center / the cost code

So the sentence is talking about a specific cost center, not just any cost center.

Yes, the basic meaning of stå is to stand, but in Norwegian it is also very commonly used in a more abstract sense to mean:

• be written
• appear
• be listed
• be stated

So in Kostnadsstedet står i reiseregningen, står does not mean the cost center is physically standing somewhere. It means the cost center appears / is listed / is written in the travel expense report.

Reiseregningen is the definite singular form of reiseregning.

It is a compound noun:

• reise = travel
• regning = bill / account / statement

In work and administrative contexts, reiseregning usually means a travel expense claim/report rather than a simple travel bill.

Forms:

• en reiseregning = a travel expense report
• reiseregningen = the travel expense report

In Norwegian, i is often used where English might say in or sometimes even on, especially when talking about information contained inside a document, system, or record.

So:

• i reiseregningen = in the travel expense report

This is natural Norwegian usage. English often says on the form or in the report, but Norwegian commonly uses i for this kind of context.

Yes, uavhengig av is a fixed expression meaning:

• regardless of
• independent of

Examples:

• uavhengig av pris = regardless of price
• uavhengig av vær = regardless of the weather
• uavhengig av om ... = regardless of whether ...

So in this sentence, it introduces something that does not affect the main statement.

Because om here means whether.

The structure is:

• uavhengig av + noun
• uavhengig av om + clause

Compare:

• uavhengig av været = regardless of the weather
• uavhengig av om det regner = regardless of whether it is raining

So in your sentence:

• uavhengig av om bompengene øker = regardless of whether the toll charges increase

Not exactly. Here om means whether, not ordinary conditional if.

In English, if can mean both:

• if = under the condition that
• if / whether = expressing uncertainty

Norwegian often separates these more clearly:

• om = whether
• hvis = if in a conditional sense

In this sentence, the meaning is whether the toll charges increase, so om is the natural choice.

Because bompenger is normally used in the plural, and here it is also definite.

Forms:

• bompenger = toll charges / road tolls
• bompengene = the toll charges / the tolls

This follows the pattern of penger (money), which is also plural in Norwegian.

So:

• om bompengene øker = whether the toll charges increase

Norwegian often uses the present tense for:

• general truths
• regular situations
• future situations when the context is clear

So om bompengene øker can mean:

• if/whether the toll charges increase
• if/whether the toll charges go up

This is very natural in Norwegian. English also often does something similar after if or whether.

Because om bompengene øker is a subordinate clause, and subordinate clauses in Norwegian usually keep normal subject + verb order.

So you get:

• om bompengene øker
  • bompengene = subject
  • øker = verb

This is different from main clauses, where Norwegian often has V2 word order and the verb comes second.

Grammatically, you could make other versions, but the definite forms here are natural because the sentence is probably referring to specific, known items in a work/administrative context.

• kostnadsstedet = the specific cost center
• reiseregningen = the specific travel expense report
• bompengene = the toll charges being discussed

Using definite forms often suggests that both speaker and listener already know which items are meant.

Yes. Norwegian makes very frequent use of compound nouns, and kostnadssted is a good example.

It is built from:

• kostnad = cost
• sted = place

Together, kostnadssted means something like cost center / cost allocation unit / cost code, depending on the business context.

This is extremely common in Norwegian: instead of using several separate words, Norwegian often combines them into one noun.

It can be divided into three parts:

1. Kostnadsstedet står i reiseregningen

   • main clause
   • The cost center is listed in the travel expense report

2. uavhengig av

   • linking expression
   • regardless of

3. om bompengene øker

   • subordinate clause
   • whether the toll charges increase

So the whole sentence has this structure:

• [Main clause] + [fixed expression] + [subordinate clause]

That is a very common and useful Norwegian pattern.
