How to use it's
Use it's only when you could write it is or it has instead.
- It's important to cite your sources. (it is)
- It's been three weeks since the deadline. (it has)
- I think it's going to rain. (it is)
How to use its
Use its to show that something belongs to an animal, object, organisation or idea. Like his, her and their, it never takes an apostrophe.
- The university updated its policy.
- Every theory has its limits.
- The cat licked its paw.

How to remember the difference
Do the one-second test: read the sentence aloud with it is. If it makes sense, write it's. If it sounds wrong ("the dog wagged it is tail"), write its. Also remember that possessive pronouns never use apostrophes: his, hers, ours, yours, theirs, its.
Tricky cases and exceptions
Why the apostrophe rule feels backwards. Most possessive nouns use an apostrophe (the dog's bowl), so writers expect it's to be possessive. But pronouns follow a different pattern, and the apostrophe in it's marks missing letters, not possession.
"It's" meaning "it has". This only works when has is a helper verb: "It's been ages" is fine, but "It's a red cover" means it is, not it has.
Its' is never correct, in any context.
Its vs it's in academic writing
Many academic style guides discourage contractions in formal essays, so you will rarely need it's at all: write it is or it has in full. That leaves its, which you will use often when writing about studies, theories, texts and organisations ("the study and its limitations"). A search for "it's" before submitting is a fast proofreading check.
