"How you doing" appears often in speech and informal messages, but in standard English it usually needs an auxiliary verb: "How are you doing?" Keep the short form for frank, clearly casual contexts; use the full question or a polite rewrite for work, school, and formal writing.
Quick answer
Use "How are you doing?" in most writing. "How you doing?" is fine in casual speech or stylized dialogue, but avoid it in emails, reports, and assignments.
- Formal: "How are you doing?" or a precise opener like "I hope you're doing well."
- Casual: the short form works for close friends or informal chat-match tone to the audience.
- Work/school: prefer full forms or task-specific questions (see examples below).
Core explanation: why the auxiliary matters
English questions normally require an auxiliary (do/does/did, be forms, or modal verbs) and often subject-auxiliary inversion. "How you doing?" drops the auxiliary "are," so it lacks the standard question structure and reads as a clipped spoken form.
Leaving out the auxiliary can confuse readers about tense and formality. In speech the listener supplies the missing verb from context, but on the page that shortcut looks incomplete.
Real usage: when the short form is acceptable
Reserve the short form for clearly informal contexts: texting friends, casual dialogue, or playful social posts. Even then, consider the relationship and the channel-what reads fine in a group chat may feel unprofessional in a workplace Slack thread.
- Use "How you doing?" when you want a relaxed, conversational voice.
- Use "How are you doing?" for neutral friendliness that's safe across contexts.
- Replace with a task-focused opener in professional settings: "Could I get an update on X?"
Hyphenation and spacing note
Underscores and glued forms like "how_you_doing" are always incorrect in normal prose. Hyphens are rare with phrases like this; treat the greeting as separate words and avoid punctuation that mimics code or usernames.
- Correct: How are you doing?
- Incorrect: How_you_doing, How-you-doing

How to fix your sentence (quick repair checklist)
Fix questions by checking the whole sentence, not just the phrase. This list helps you choose between a simple fix and a cleaner rewrite.
- Step 1: Identify whether you need a true question. If yes, insert the correct auxiliary: are / is / do / did / have / has / did.
- Step 2: Match tone to audience-formal? rewrite to a polite opener or task-specific ask.
- Step 3: Read the full sentence aloud to check flow; adjust word order or punctuation if needed.
Examples of rewrites:
- Original: How you doing on the report?Simple fix: How are you doing on the report?
Rewrite: Could I get a quick update on the report? - Original: How you doing tonight?Simple fix: How are you doing tonight?
Rewrite: Are you free tonight to meet up? - Original: How you doing? I need the file.Simple fix: How are you doing? I need the file.
Rewrite: I hope you're well-could you send the file when you have a moment?
A simple memory trick
Link the auxiliary to the question word. Picture "How" + "are" as a single spoken unit for questions: "How are..." When you hear "How you..." mentally insert "are" and decide if the tone should be formal or casual.
- If it sounds incomplete aloud, add the auxiliary on the page.
- Train yourself by searching drafts for the short form and fixing them in one pass.
Similar mistakes and quick grammar notes
Watch for other omissions and confusions that follow the same pattern.
- Missing auxiliaries in questions: "You coming?" → "Are you coming?"
- Subject-auxiliary inversion errors: "Why she left?" → "Why did she leave?"
- Confusing contractions and possessives: "your" vs. "you're"-always expand in your head if unsure.
- Spacing and hyphenation: avoid underscores and unnecessary hyphens in ordinary text.
