its vs. it's

Use its (no apostrophe) for possession. Use it's (with an apostrophe) only as a contraction for it is or it has. When in doubt, expand it's → it is / it has; if the sentence still makes sense, keep the apostrophe.

Quick answer

its = possessive (no apostrophe). it's = contraction of it is or it has.

• its = ownership (like his, hers, ours).
• it's = it is OR it has (expansion test).
• Never write its' - that form is incorrect.

Core explanation (grammar)

its is the possessive pronoun: it shows that something belongs to or is a part of something else (the company increased its revenue).

it's is a contraction combining it + is or it + has (it's late = it is late; it's arrived = it has arrived).

• Possessive pronouns like its, yours, theirs never use an apostrophe.
• Use the expansion test: if "it is" or "it has" fits, use it's; if not, use its.
• Avoid forms like its' or it s - they are wrong.

Memory trick

Apostrophes mark missing letters. Try expanding: if "it is" or "it has" reads naturally, the apostrophe belongs (it's). If the meaning shows ownership, no apostrophe (its).

• Substitute with his/her: if "his" fits, the possessive form (its) is probably correct.
• Ask: possession or contraction? Expand to check.

• Example: "It's going to rain." → expand: "It is going to rain." (works → it's)
• Example: "The device lost its charge." → "The device lost his charge" doesn't fit (so it's possessive → its)

Real usage: tone and where to be strict

In casual writing (texts, chats, quick emails), contractions like it's are normal. In formal writing (academic work, legal text, some business reports), prefer the expanded forms it is or it has to avoid an overly casual tone.

• Possessive its is neutral across registers; the rule doesn't change.
• In business, run the expansion test for ambiguous phrases like "its policy" or "it's policy."

• Example (casual): "It's attached." is fine in a quick email.
• Example (formal): "The file is attached." or "It is attached." reads more professional.

Rewrite help: quick rewrites to remove doubt

If the expansion test still feels unclear, rewrite the sentence so the choice vanishes: name the owner, expand the contraction, or rephrase the clause.

• Replace the possessive with "the X of it" or name the possessor: its settings → the settings of the machine / the machine's settings.
• Replace the contraction with the full phrase: it's → it is / it has.
• Simplify the sentence: remove the phrase that causes confusion when possible.

• Rewrite: "It's deadline is today." → "The deadline is today." OR "Its deadline is today."
• Rewrite: "I don't know if it's decision is final." → "I don't know if the decision is final."
• Rewrite: "We checked it's battery." → "We checked the battery." OR "We checked its battery."

Try your own sentence

Test the full sentence in context. Expand any it's to it is / it has; if that sounds wrong, use its or rewrite. Context usually makes the correct choice obvious.

Spacing, apostrophes, and hyphenation notes

Never add spaces around an apostrophe: write it's (not it 's). Pronoun possessives (its, yours, theirs) never use an apostrophe. Hyphens are unrelated to apostrophes; don't confuse them.

• Correct: don't, it's, we're - no spaces around the apostrophe.
• Never write its' - the correct possessive pronoun is its.
• Hyphens (-) are different from apostrophes (').

• Spacing example: Wrong: it 's late.
  Right: it's late.
• Apostrophe example: Wrong: Its' handle was loose.
  Right: Its handle was loose.

Similar mistakes to watch for

Apply the same expansion and possession tests to other common confusions: your vs you're and their vs they're vs there.

• your (possession) vs you're (you are)
• their (possession) vs they're (they are) vs there (place)
• Pronoun possessives (its, yours, theirs) never use apostrophes.

• Similar - Wrong: I left it's in the car. Right: I left it in the car. (or: I left its case in the car.)
• Similar - Wrong: Your going to love this. Right: You're going to love this.

FAQ

Is "its" ever spelled with an apostrophe?

No. The possessive pronoun is always its (no apostrophe). An apostrophe indicates a contraction, not possession for pronouns.

How do I check a sentence quickly?

Expand any it's to it is or it has. If that reads naturally, keep the apostrophe. If not, use its or rewrite the sentence so the owner is clear.

Can I always replace "its" with "the X of it"?

Yes. Rephrasing to "the X of it" or naming the possessor removes ambiguity and often improves clarity.

Why do people write "its'" by mistake?

Because many possessive nouns use an apostrophe + s (the dog's leash), people assume all possessives need an apostrophe. Pronouns follow different rules.

Is spellcheck enough to catch this?

Not always. Spellcheck may not flag its vs it's because both are valid words. Use the expansion test and read the sentence aloud.

Soft CTA - quick practice habit

Before sending important messages, take 30 seconds: scan for apostrophes, expand any it's to it is / it has, and rewrite if expansion doesn't fit. That simple habit removes almost all its/it's errors.
