In modern English, say “Do I have to…?” to ask whether something is required. “Have I to…?” is an old-fashioned form. You will meet it in older books, but it sounds odd in everyday speech and writing today.

Why you need “do”
When have to means “must” (an obligation), modern English treats have like an ordinary verb. Ordinary verbs make questions with do, does or did.
Pattern: Do / Does / Did + subject + have to + base verb?
- Do I have to submit this report today?
- Does she have to attend the meeting?
- Did they have to pay extra for shipping?
After does or did, the word is always have, not has or had. Say “Does she have to go?”, not “Does she has to go?”
| Statement | Question | Negative |
|---|---|---|
| I have to leave. | Do I have to leave? | I don’t have to leave. |
| She has to attend. | Does she have to attend? | She doesn’t have to attend. |
| They had to pay. | Did they have to pay? | They didn’t have to pay. |
What about “Have I to”?
Older English let have jump in front of the subject to make a question, the same way be does in “Am I late?” So “Have I to go?” was once ordinary English. Modern English no longer does this with have to, so these sound outdated:
- Have I to finish this work now? (modern: Do I have to finish this work now?)
- Has she to report to HR? (modern: Does she have to report to HR?)
You may still see this form in older writing. In an exam, email or conversation, use do.
Other ways to ask about obligation
| Expression | Feel | Example |
|---|---|---|
| Do I have to…? | Standard, everyday | Do I have to bring my passport? |
| Have I got to…? | Informal, most common in British English | Have I got to do this right now? |
| Must I…? | Formal, a little strong | Must I present the documents in person? |
| Am I required to…? | Formal, official | Am I required to submit a paper copy? |
| Is it necessary to…? | Polite, neutral | Is it necessary to reserve a seat? |
| Have I to…? | Old-fashioned | Have I to stay here? (avoid) |
Tone matters too. “Do I have to…?” can sound reluctant, as if you would rather not. If you are asking an official for information, “Am I required to…?” or “Is it necessary to…?” sounds more neutral.
Don’t have to is not the same as mustn’t
- You don’t have to wear a tie. (It is optional.)
- You mustn’t enter the lab. (It is forbidden.)
Learners often mix these up because their own language may use one word for both ideas.
