I tilfelle selskapet skal refundere utgiftene, må du oppgi referansenummeret.

I tilfelle here means something like in case.

It is close to hvis (if), but they are not always interchangeable.

• hvis usually introduces a straightforward condition: if X happens, then Y
• i tilfelle often has a more precautionary or contingency-like feel: in the event that / in case

In this sentence, i tilfelle selskapet skal refundere utgiftene means:

• if the company is going to reimburse the expenses
• in case the company is supposed to reimburse the expenses

So yes, it is similar to hvis, but i tilfelle can sound a bit more like preparing for a possible situation.

Selskapet is the definite singular form of selskap (company), so it means the company.

Forms:

• et selskap = a company
• selskapet = the company

Norwegian often uses the definite form when the specific thing is already known from the context. Here, it is not just any company, but a particular one: the company.

Skal is a modal verb. It can mean different things depending on context, such as:

• shall / will
• is going to
• is supposed to
• is to

In this sentence, selskapet skal refundere utgiftene suggests that the company is expected, supposed, or set to reimburse the expenses.

So skal is not just simple future here. It has a sense of plan, arrangement, or obligation.

Compare:

• Selskapet refunderer utgiftene = The company reimburses / is reimbursing the expenses
• Selskapet vil refundere utgiftene = The company will reimburse the expenses
• Selskapet skal refundere utgiftene = The company is supposed to / is set to reimburse the expenses

Utgiftene is the definite plural of utgift (expense), so it means the expenses.

Forms:

• en utgift = an expense
• utgifter = expenses
• utgiftene = the expenses

The definite form is used because these are specific expenses already understood from the situation, not expenses in general.

Refundere means to reimburse or to refund.

It is a fairly formal word and is often used in business, finance, travel claims, insurance, and administrative contexts.

In everyday speech, Norwegians may also use other expressions depending on context, but refundere is completely natural in formal written language.

Examples:

• Selskapet refunderer reisekostnader. = The company reimburses travel costs.
• Beløpet blir refundert. = The amount will be refunded.

Må means must / have to, and oppgi means state, provide, give, specify.

So må du oppgi means:

• you must provide
• you have to state
• you need to give

In administrative or form-related language, oppgi is very common when someone must enter or provide information.

Examples:

• Du må oppgi navn. = You must provide your name.
• Vennligst oppgi kundenummer. = Please state your customer number.

This happens because the sentence begins with a subordinate clause:

I tilfelle selskapet skal refundere utgiftene, ...

After an element is placed first in a Norwegian main clause, the finite verb comes second. This is the usual V2 word order rule.

So the main clause becomes:

• må du oppgi referansenummeret

instead of

• du må oppgi referansenummeret

If the sentence started directly with the main clause, you would say:

• Du må oppgi referansenummeret.

But with the fronted clause first, inversion happens:

• I tilfelle ..., må du oppgi referansenummeret.

This is very important in Norwegian.

It is an introductory subordinate clause expressing a condition or contingency.

The full sentence structure is:

• Subordinate clause: I tilfelle selskapet skal refundere utgiftene
• Main clause: må du oppgi referansenummeret

This is why there is:

1. a comma after the first clause, and
2. inversion in the main clause (må du, not du må)

The comma separates the introductory subordinate clause from the main clause.

So:

• I tilfelle selskapet skal refundere utgiftene, må du oppgi referansenummeret.

This is standard Norwegian punctuation when a subordinate clause comes before the main clause.

Literally, it means something like:

• state the reference number
• give the reference number
• provide the reference number

Referansenummeret is the definite singular form of referansenummer (reference number), so it means the reference number.

This suggests a specific reference number that the listener is expected to know or have.

Because the sentence is referring to a specific, relevant reference number, not just any reference number.

Compare:

• et referansenummer = a reference number
• referansenummeret = the reference number

In instructions and formal writing, Norwegian often uses the definite form when the item is understood from the context.

So this sentence implies: you must provide the reference number connected with this case/request/expense claim.

It can do both.

Du literally means you (singular), but in instructions and general statements it is also commonly used like English you in a general sense.

So here it may mean:

• one specific person being addressed, or
• people in general who are reading the instruction

This is very normal in Norwegian.

Yes, something like this would be possible:

• Hvis selskapet skal refundere utgiftene, må du oppgi referansenummeret.

That would sound more directly like if the company is going to reimburse the expenses.

Using i tilfelle gives a slightly different nuance, more like preparing for that possibility. Both can work, but they are not always perfect substitutes in every context.

It sounds neutral to formal, especially because of words like:

• refundere
• oppgi
• referansenummeret

This is the kind of sentence you might see in:

• forms
• official instructions
• customer service messages
• reimbursement policies
• company or government websites

It is not unnatural in everyday Norwegian, but it definitely has an administrative tone.

Yes:

• I tilfelle = in case
• selskapet = the company
• skal = is going to / is supposed to / is to
• refundere = reimburse / refund
• utgiftene = the expenses
• må = must / have to
• du = you
• oppgi = provide / state / specify
• referansenummeret = the reference number

That gives you the full structure of the sentence without changing its meaning.
