You say “You’re coming tonight, isn’t it?” and something feels off, but you can’t say what. Question tags, those short confirmations tacked onto the end of a sentence like “isn’t it?” or “don’t you?”, follow a strict mirroring rule that most learners never get explained clearly: the tag has to match the main verb, not just repeat a generic phrase.
Once you see the mirroring pattern, question tags stop being a memorized list and become something you can build correctly for any sentence, in real time.
The Core Rule: Positive Statement, Negative Tag
If the main sentence is positive, the tag is negative. If the main sentence is negative, the tag is positive. The tag always uses the same auxiliary verb as the main sentence, and the same subject pronoun, never a different verb.
| Main Statement | Tag |
|---|---|
| You are coming, | aren’t you? |
| She isn’t ready, | is she? |
| They can swim, | can’t they? |
| He doesn’t like coffee, | does he? |
| We have finished, | haven’t we? |
Matching the Right Auxiliary Verb
This is where most mistakes happen. The tag must use the same helping verb (auxiliary) that’s already in the sentence, or “do/does/did” if the sentence has no auxiliary at all.
- Sentence has “be”: He is tired, isn’t he?
- Sentence has a modal (can, will, should): She will help, won’t she?
- Sentence has “have” (present perfect): They have left, haven’t they?
- Sentence has no auxiliary (simple present/past): You like pizza, don’t you? / She went home, didn’t she?
Special Cases That Break the Pattern
A handful of question tags don’t follow the standard rule and simply have to be memorized as fixed exceptions.
| Main Statement | Tag | Why |
|---|---|---|
| I am late, | aren’t I? | “Amn’t I” isn’t standard; “aren’t I” is the accepted irregular form |
| Let’s go, | shall we? | “Let’s” suggestions always take “shall we” |
| Nobody called, | did they? | Indefinite pronouns like “nobody” take “they” in the tag |
| Open the door, | will you? | Imperatives take “will you” as the tag |
What Your Intonation Actually Communicates
The words are only half the story. Falling intonation on the tag means you’re genuinely confident and just want agreement, close to a statement. Rising intonation means you’re genuinely unsure and asking a real question. “You’re coming, aren’t you?” said with rising intonation is a real question; the same words with falling intonation are practically a statement expecting a “yes.”
6 Common Mistakes With Question Tags
| Instead of this | Say this | Why |
|---|---|---|
| “You are coming, isn’t it?” | “You are coming, aren’t you?” | Tag must match the subject pronoun, not use “it” |
| “She is nice, doesn’t she?” | “She is nice, isn’t she?” | Must use “is,” the auxiliary already in the sentence |
| “You like pizza, do you?” as a genuine tag question | “You like pizza, don’t you?” | Positive statement needs a negative tag |
| “He hasn’t called, has he not?” | “He hasn’t called, has he?” | Negative tags contract; “has he not” is overly formal and outdated |
| “They can’t swim, can’t they?” | “They can’t swim, can they?” | Negative statement needs a positive tag |
| “Let’s go, will we?” | “Let’s go, shall we?” | “Let’s” always takes “shall we,” not “will we” |

Answer Key
- 1. aren’t you? 2. does she? 3. haven’t they? 4. can’t he? 5. shall we? 6. do they?

Make This Automatic
Question tags become instinctive once you’ve built enough of them in real conversation, since the mirroring pattern is more of a habit than a rule you consciously apply each time. Our English courses build this into real speaking practice. If you want a tutor to correct your question tags as you actually speak, you can start with a private English tutor or book a Free Lesson.

Frequently Asked Questions About Question Tags
What’s the basic rule for question tags?
A positive statement takes a negative tag, and a negative statement takes a positive tag, always using the same auxiliary verb and subject pronoun as the main sentence.
What tag goes with “I am”?
“Aren’t I?” is the standard irregular tag for “I am,” since “amn’t I” isn’t used in standard English.
What tag do I use if there’s no auxiliary verb in the sentence?
Use a form of “do”: “don’t,” “doesn’t,” or “didn’t,” depending on the tense: “You like coffee, don’t you?”
What tag do I use after “let’s”?
“Shall we?” is the fixed tag for suggestions starting with “let’s”: “Let’s go, shall we?”
How do I make a question tag for a command?
Use “will you?”: “Close the door, will you?”
Does intonation change the meaning of a question tag?
Yes: falling intonation signals confidence and expects agreement, while rising intonation signals genuine uncertainty and asks a real question.
What tag goes with “nobody” or “everyone”?
Indefinite pronouns like “nobody” and “everyone” take “they” in the tag: “Nobody called, did they?”
Can the tag use a different verb than the main sentence?
No, never. The tag must repeat the exact auxiliary already in the sentence, or use “do/does/did” if there is none.
Are question tags common in formal English?
They’re more common in spoken and informal English, used to check information, seek agreement, or soften a statement in conversation.
What’s the best way to practice question tags?
Add a tag to real statements about your own life out loud, since building the tag correctly in real time is what makes the pattern automatic.
