Here's the truth: you can nail your grammar and vocabulary, hit every word count requirement, and still tank your score because your letter format is wrong. On IELTS General Training, Task 1 isn't just testing whether you can communicate. It's testing whether you understand how formal letters actually work.
Most students hover around 6 or 6.5 on Task 1 when they could easily hit 7 or 7.5. The gap isn't in their ideas or their English—it's format mistakes that a simple checklist could've caught. This is where an IELTS letter format checker becomes invaluable. Let's break down exactly which errors cost you points, and more importantly, how to kill them.
The IELTS band descriptors explicitly grade "Task Response," which includes whether you've matched the right register and format. Mess up the letter format, and you lose points before a single grammar rule is even checked.
Here's what the examiner is actually looking for:
Skip any of these, and you'll hit a band 5 or 5.5 ceiling on Task Response alone. That's before grammar and vocabulary even get evaluated. This is where most students lose marks without realizing it. They treat format as optional when it's actually non-negotiable. Using an IELTS writing checker before submission catches these gaps instantly.
Your opening line tells the examiner everything about whether you get formality. And this is almost certainly where you're making a mistake.
The rule is simple: If you know the person's name, use it. If you don't, use "Dear Sir or Madam" or "To Whom It May Concern" for formal letters. Never—not once—use "Hi," "Hello," or "Hey" in a General Training letter, even if the prompt feels casual.
Wrong: "Hi John, I hope you're doing well. I'm writing to complain about the service I received at your hotel."
This fails on three counts. "Hi" is too casual for any formal letter. You shouldn't assume you know John that well. And the second sentence is padding that wastes words you could use for actual content.
Right: "Dear Sir or Madam, I am writing to lodge a formal complaint regarding the poor service I experienced during my stay at your hotel last month."
Direct. Formal. Clear purpose. The examiner knows you understand letter conventions in the first five words.
Quick tip: When the prompt gives you a name (like "Write to your manager, Mr. Harris"), always use it: "Dear Mr. Harris" or "Dear Ms. Chen." Using a title is more formal than jumping straight to a first name, and it proves you read the prompt.
A letter isn't an essay. You don't need five sprawling paragraphs. You need clean, separated blocks where each one does one job. Understanding proper task 1 letter structure is the fastest way to improve your coherence score.
Here's the structure that works:
Your entire 150-word letter fits into this mold. Most students either cram it all into one giant block (tanking coherence) or scatter paragraphs randomly (tanking structure). Neither works.
Wrong (no paragraph breaks): "Dear Sir or Madam, I am writing to apply for the position advertised on your website. I have five years of experience in marketing and I believe I am suitable for this role. I have worked with brands like XYZ and ABC. My skills include project management and team leadership. I would appreciate the opportunity to discuss my qualifications further. Yours faithfully, Jane Smith"
Everything's jammed together. The examiner can't see your organizational thinking. Your Coherence & Cohesion score will suffer for it.
Right (clear structure): "Dear Sir or Madam, I am writing to apply for the Marketing Manager position advertised on your website. I have five years of experience in marketing and believe I am well-suited to this role. During my time at ABC Corporation, I managed campaigns that increased brand awareness by 40%. My core competencies include project management, team leadership, and digital strategy. I would welcome the opportunity to discuss how my background aligns with your company's goals. Yours faithfully, Jane Smith"
Notice the white space. Notice how each paragraph has a clear job. Notice how the ideas flow naturally. That's what band 7 structure looks like.
Your sign-off is the last thing the examiner reads. Get it right.
For formal letters: Use "Yours faithfully" or "Yours truly" (then a line break, then your full name).
For semi-formal letters: Use "Best regards," "Kind regards," or "Sincerely" (followed by your name).
Here's the actual rule: If you started with "Dear Sir or Madam" (because you don't know the person), you must close with "Yours faithfully." If you used a person's name, you can use "Yours sincerely" or "Kind regards."
Wrong: "Thanks, John" or "XOXO, Me" or (worst of all) no sign-off whatsoever.
These destroy your score because they're inappropriate for every formal and semi-formal context. You're showing the examiner you don't know letter conventions at all.
Right: "Yours faithfully, [space] Margaret Thompson" or "Kind regards, David Kumar"
Simple. Professional. Correct.
You've got exactly 150 words minimum. That's tight. Every sentence needs to move you toward your purpose. Filler kills you in two ways: it eats words you should spend on content, and it tanks your Task Response score because you're not developing your ideas.
Watch out for these common killers:
Wrong: "I hope this letter finds you well. I am writing to complain about the poor service I received at your restaurant. I am very unhappy about what happened. I look forward to hearing from you soon. Yours faithfully..."
That's 4 throwaway words at the start and 5 at the end. 9 words that could've explained what went wrong, when it happened, or what outcome you need. Your Task Response score reflects this lost specificity.
Right: "I am writing to lodge a formal complaint regarding the poor service I received during my visit to your restaurant on 15 August. Upon arrival, my table was not ready despite my reservation, and the waiter was dismissive when I raised the issue. I expect compensation for the wasted evening and a detailed explanation of how this will be prevented in future. Yours faithfully..."
Every sentence does real work. You're being specific. You're showing the examiner a band 7 approach to Task Response.
Quick tip: Don't count your salutation and sign-off toward the 150 words. Only count the body content. This means your actual paragraphs need to carry real weight, no room for filler.
IELTS Task 1 letters are either formal (to organizations, government bodies, or unknown people) or semi-formal (to people you know, like a teacher or colleague). The mistake most students make? They start formal and then slip into casual language mid-letter.
Wrong (inconsistent register): "Dear Sir or Madam, I am writing to lodge a complaint about my accommodation. The room was disgusting and I couldn't sleep. Also, the staff were so rude to me lol. I would appreciate a full refund. Yours faithfully..."
You started formal, dipped into colloquial language ("disgusting," "lol"), and lost all consistency. Your Coherence & Cohesion and Task Response scores will take a hit.
Right (consistent formal register): "Dear Sir or Madam, I am writing to lodge a formal complaint regarding the unsatisfactory standard of accommodation I received during my recent stay. The room was not adequately cleaned and contained visible signs of neglect. Additionally, the staff were unhelpful when I reported these issues. I expect a full refund and a detailed response regarding your cleaning standards. Yours faithfully..."
Formal language throughout. No slips. No register shifts. The examiner sees competence and consistency.

Does IELTS care if you indent paragraphs or use line breaks? Technically, the band descriptors don't mention it. But in practice, one or the other signals that you know letter formatting. What absolutely doesn't work is having everything run together with no visual separation.
Pick one method and commit to it:
On exam day, you'll either hand-write or type into a test interface. Either method works fine. What matters is that your letter visibly separates into distinct sections.
Quick tip: If you're writing by hand on exam day, indenting is easier than trying to create perfect blank lines. Start practicing the indent method now until it becomes automatic.
Don't rely on memory. Use this checklist every single time before submission. It takes 30 seconds and prevents the formal letter mistakes that tank band scores.
Print this. Bookmark it. Use it before every submission. This checklist alone moves most students from 6 to 6.5 or 6.5 to 7 on Task Response. And Task Response is 25% of your Writing grade, so this matters.
Different prompts demand different registers. Knowing the difference is crucial, because getting it wrong tanks your score immediately.
Write a formal letter when:
Write a semi-formal letter when:
The examiner can tell within seconds which one you should've written. If you use formal language for a semi-formal letter to a friend, you'll lose marks. If you use casual language for a formal complaint letter, you'll lose marks. Match the register to the prompt.
Letters often require you to reference specific information: dates, times, booking numbers, or product details. One small error here damages your Task Response score because you've either misunderstood the prompt or made up information.
Before you write, re-read the prompt and pull out every specific detail. If the prompt says "you stayed at the hotel from 12-15 August," write exactly "12-15 August." If it says "your booking number is AC4829," use that exact number.
Many students invent details because they think it makes their letter sound more convincing. It does the opposite, examiners notice immediately when data doesn't match the prompt, and it costs you Task Response points. Our breakdown of how to avoid misreporting numbers in Task 1 shows exactly which details matter most and how to reference them correctly without inventing anything.
