The Basic Rule: Its or It’s?

Let’s start with the main rule. Let’s practice this rule together.
Its and it’s sound exactly the same when you say them out loud, so you can’t rely on your ears to know which one to write. The spelling depends only on the meaning of the sentence, which is why the substitution test below is so useful.
- Use it’s (with an apostrophe) when it is a contraction, or short form, of it is or it has.
- Use its (with no apostrophe) to show possession or that something belongs to something else. It usually comes before a noun, like in its name, its color, or its policy.
Think about other possessive words you know, like his, hers, ours, yours, and theirs. None of them use an apostrophe, and its follows the same pattern.
Here’s the only rule you need to remember:
If you can replace the word with “it is” or “it has” in your sentence, the correct choice is it’s. If not, use its.
Your Cheat Sheet:it’s = it is / it has its = belonging to or connected with it
The 3-Second Substitution Test
This simple test is the best way to decide which word to use. You can use it anytime you’re writing, even during an exam. Here’s how it works.
- Step 1: When you see its or it’s, try replacing it with “it is” or “it has”.
- Step 2: If the sentence still makes sense, you should use it’s.
- Step 3: If the sentence does not make sense and it shows that something belongs to something else, you should use its.
Let’s look at some examples.
- Sentence: “It’s raining.”
- Test: “It is raining.”
- Result: The sentence makes sense. The correct form is it’s.
- Sentence: “It’s been a long day.”
- Test: “It has been a long day.”
- Result: The sentence makes sense. The correct form is it’s. The way English uses “have” and “has” can be tricky. For more practice, you might find this guide on the difference between HAVE, HAVE GOT, and GOT very helpful.
- Sentence: “The company changed its policy.”
- Test: “The company changed it is policy.”
- Result: This does not make sense. The policy belongs to the company, so this is possessive. The correct form is its.
That’s all there is to it! This simple substitution helps you choose the right word every single time.

Optional Note: Why Its Has No Apostrophe
Have you ever wondered why the possessive its doesn’t have an apostrophe, even though we use an apostrophe for possessives like Maria’s book? The simple answer is that its follows the same pattern as other possessive pronouns like his, hers, yours, ours, and theirs. None of these words use an apostrophe to show possession, and its is just the same.
