Carve out and carve-out look like the same word wearing two different outfits, and in a sense they are — but which outfit is correct depends entirely on whether you're using a verb or a noun.
The rule is simple to state and easy to get wrong in practice: the verb is always two open words, never hyphenated, even in the infinitive — "to carve out," not "to carve-out." The noun and modifier are normally hyphenated: "a carve-out," "a carve-out provision," "carve-out financial information."
Why the two forms exist side by side
This form split trips up even fluent writers because the verb and the noun look almost identical on the page and sound identical out loud — only the spelling on paper reveals which one you meant. As a verb, "carve out" stays two open words in every tense: carve out, carves out, carved out, to carve out. There is no version of the verb that takes a hyphen, no matter how the sentence is structured around it.
As a noun or attributive modifier, standard usage hyphenates it instead: "the agreement includes a carve-out," "the carve-out provision covers existing customers." The hyphen signals that the two words are now functioning as a single unit — a thing, not an action.
"The board decided to carve out the logistics unit before Q3."
"The resulting carve-out will report separately starting next quarter."

The two mistakes to watch for
The most common mistake is hyphenating the verb by analogy with the noun — writing "to carve-out the unit" because the noun form nearby has a hyphen and it feels consistent. It isn't; the verb never takes one. The mirror-image mistake is dropping the hyphen from the noun, writing "a carve out provision" instead of "a carve-out provision." Both errors are small on the page but visible in exactly the kind of writing where readers expect precise, conventional spelling — policy text, deal memos, formal contract summaries.
"'To carve-out the unit' and 'a carve out provision' are both form errors; the verb stays open, the noun takes the hyphen."
A useful check when you're unsure: ask whether the word is doing something (an action, a verb) or naming something (a thing, a noun). If it's doing something, leave the hyphen out. If it's naming something, put it in.
Practice scenarios
Practice using carve out and carve-out in situations like:
- writing a formal memo that uses both the verb and the noun form correctly
- proofreading a contract summary for a dropped or misplaced hyphen
- deciding whether a sentence needs the action form or the thing form
Useful practice phrases:
- "The board decided to carve out [the unit] before [deadline]."
- "The resulting carve-out will [report/operate] separately starting [date]."
- "The [document] includes a carve-out provision for [category]."
The verb acts; the noun is hyphenated because it names.
Keep that one distinction straight and the rest of the spelling takes care of itself.
