IELTS Writing Task 1 Letter Signature Mistakes: Band 5 to 8 Checker Guide

Here's the thing that trips up most IELTS students: you can nail the content, hit all your points, use great vocabulary, and still lose marks because your closing is wrong. I'm not exaggerating. The way you end your letter—your closing salutation and signature—directly affects your Coherence and Cohesion score. Get it wrong, and the examiner thinks you don't understand formal English conventions. That's a band killer.

This is where the leaks happen. You spend 20 minutes crafting a solid letter body, nailing the tone, throwing in advanced words. Then you finish with "Thanks! John" or "Yours sincerely John Smith" (no comma). These tiny errors pile up. The examiner sees careless mistakes stacking, and your band drops from 7 to 6.5—or worse.

In this guide, you'll see exactly what examiners look for in your letter closing, compare real Band 5 vs Band 8 examples side by side, and grab a practical checklist you can use before submitting any formal letter in Task 1. Use our free IELTS writing checker to catch these errors automatically.

Why Your Letter Ending Actually Matters for IELTS

IELTS Writing Task 1 tests your ability to communicate in formal, appropriate English. Your closing salutation and signature are your final 2 lines on the page. That's your last chance to show the examiner you understand formal conventions.

According to the IELTS Band Descriptors, Band 7-8 writers "use a variety of linking words accurately and appropriately" and organize their writing with clear paragraphing. Your closing is the final paragraph. It needs to be flawless.

Band 5-6 writers stumble here all the time: inconsistent formality, missing punctuation, wrong sign-off phrases. These aren't content mistakes. They're convention mistakes. And examiners catch them every time.

The Three Parts of a Correct Letter Ending

A formal letter closing has three parts. Every single one matters.

1. Closing salutation: The phrase that signals the end (like "Yours sincerely" or "Yours faithfully").
2. Punctuation: A comma after the closing salutation (British English standard).
3. Signature: Your full name, written clearly on the next line.

Miss any of these, and marks come off. Let's dig into each one.

Closing Salutation Mistakes: What IELTS Examiners Really See

Your closing salutation is the goodbye phrase. It has to match the tone of your entire letter and fit with how you opened it.

Rule 1: Match your opening to your closing.

This is the rule that separates Band 5 from Band 7. If you opened with "Dear Sir or Madam" (formal), you close with "Yours faithfully" or "Yours sincerely." If you opened with "Dear Mr. Chen," close with "Yours sincerely." If you opened with "Dear John," use "Kind regards" or "Best wishes." Mismatches scream Band 5 to the examiner.

Rule 2: Use only British formal closings for IELTS Task 1.

These are your safe options for formal IELTS letters:

• "Yours faithfully" - when you don't know the reader's name.
• "Yours sincerely" - when you know the reader's name.
• "Kind regards" - semi-formal to formal.
• "Best regards" - semi-formal to formal.

American closings like "Sincerely," "Respectfully," or "Warm regards" show up in IELTS less often and can cost you marks. Stick to British options. Semi-formal closings like "Best wishes" only work if your entire letter is semi-formal (for example, requesting information from a university admissions officer you've emailed before).

Rule 3: Don't invent closing salutations.

Some students create phrases like "With appreciation," "Respectfully yours," "Warm greetings," or "Thanking you." These aren't real IELTS closings. Examiners read thousands of IELTS letters. Non-standard closings stand out immediately—and not in a good way.

The Comma After Your Closing Salutation

This is tiny. This is also non-negotiable.

In British English, you put a comma after your closing salutation. Not a period. Not nothing. A comma. This small detail is what sometimes separates Band 7 from Band 5.

The examiner is trained to spot punctuation errors. A missing comma after your closing salutation counts as a grammatical mistake. It hits your Grammatical Range and Accuracy score.

Signature Format: Full Name vs. Initials

Your signature comes on the line below your closing salutation. This is where you write your name.

Always use your full name. First name and last name, both capitalized, on one line. This is professional, clear, and expected.

Some students use just initials or only their last name. Don't. It looks incomplete and unprofessional. IELTS examiners expect full names in formal letters.

There's one exception: if the IELTS question explicitly tells you to sign as initials (e.g., "Sign as M.C."), follow that instruction. But this is rare.

Real IELTS Examples: Band 5 vs Band 8 Closings

Let's look at how different letters should close at different band levels.

Example 1: Complaint Letter to a Hotel

You opened the letter: "Dear Mr. Thompson,"

Example 2: Request Letter to a University

You opened: "Dear Sir or Madam,"

Example 3: Request Letter to Your Landlord

You opened: "Dear Mrs. Patel,"

Common Closing Mistakes That Cost You Points

Here's what we see most often in Band 5-6 letters:

1. Missing the comma: "Yours sincerely" instead of "Yours sincerely," (Grammatical Range and Accuracy takes a hit.)
2. Wrong closing salutation: Using "Kind regards" with a formal "Dear Sir or Madam" opening (Shows you don't understand register.)
3. Casual sign-offs: "Thanks," "Cheers," "Talk soon," "Looking forward" (Kills your formality.)
4. American closings: "Sincerely," "Warm regards," "Respectfully yours" (Not standard for British IELTS.)
5. No closing at all: Letter just ends with the last sentence, no salutation (Marks as incomplete.)
6. Initials instead of full name: "J.S." instead of "James Smith" (Looks unfinished.)
7. Handwritten signature: Literally signing your name instead of typing it (IELTS expects typed full name.)

Your IELTS Letter Closing Checklist

Run through this before you finish any Task 1 letter. Takes 30 seconds. Can save you half a band.

• Opening salutation identified (Dear Sir or Madam / Dear [Name])?
• Closing salutation matches the opening's formality level?
• Closing is one of these: Yours faithfully, Yours sincerely, Kind regards, Best regards?
• Comma placed directly after the closing salutation?
• Full name written on the line below (not initials, not a handwritten signature)?
• Name capitalized correctly?
• No spelling errors in your name?

All seven checked: Band 7-8 level. One or two missed: Band 6 range. Three or more: Band 5.

How Much Do Closing Errors Actually Cost?

A single closing mistake (missing comma, wrong salutation) typically costs 0.5 bands in Grammatical Range and Accuracy or Coherence and Cohesion. Multiple errors compound the loss. That's why getting it right matters. It's quick marks you can't afford to leave on the table.

If you're aiming for Band 7 or above, your letter closing must be flawless. Use an IELTS writing checker to catch punctuation errors and register problems before they cost you marks.
