How to write a salary increase letter

Published · Hiring and HR letters

A salary increase letter confirms a decision that has already been made. It is not the place to negotiate. Done well, it tells the employee exactly what changes, from when, and what stays the same, so payroll and the employee's own records agree.

Settle the details before you write

  • The new salary and the old one. State both, so the increase is unambiguous and easy to check against payroll.
  • The effective date. The first day the new rate applies, and whether any back pay covers an earlier period.
  • The pay period. Annual salary paid monthly is not the same as an hourly rate, and a change to either may affect overtime or benefits.
  • Who approved it. A named approver or a reference to the approval record is useful if payroll or an auditor asks later.

What to include

  1. Employee details. Full name, job title and department, so the letter matches the personnel file.
  2. The change. Current salary, new salary, effective date and pay frequency. If the increase is a percentage, give the resulting amount as well.
  3. Why. One or two sentences: an annual review, a promotion, a market adjustment or a change in responsibilities. Keep it factual.
  4. What does not change. Benefits, bonus eligibility, notice periods and other contract terms stay as they are unless a separate letter says otherwise.
  5. Next steps. Who to contact with questions, and how the employee confirms receipt if your process asks for it.

Sample wording

Dear [Employee name],

I am writing to confirm that your salary will increase from [old salary] to [new salary] per year, effective [date]. Your salary will continue to be paid [monthly] in accordance with the usual payroll schedule.

This increase reflects [the annual review / your promotion to [title] / a market adjustment]. Your other terms and conditions of employment, including [benefits and bonus eligibility], are unchanged.

Please contact [name] in HR if you have any questions.

Yours sincerely,
[Name]
[Title]

Mistakes that cause problems later

  • Promising a future increase. "We will review again in six months" can be read as a commitment. Say "eligible for review" if that is what you mean.
  • Vague amounts. "A 5% rise" without the new salary leaves room for a disagreement about the base. Give both figures.
  • Changing other terms by implication. A new title or hours can change overtime, benefits or notice. If those change, issue a contract variation as well.
  • Inconsistent treatment. Pay decisions should be explainable and documented. Keep the reasons and the approval with the letter.

Deliver it properly

Discuss the increase in person or on a call first, then send the letter the same day. Ask the employee to confirm receipt if your process requires it, and file the signed or acknowledged copy with the approval record. Payroll should receive the change before the effective date, not after the first pay run.

The free salary increase letter template asks for the old and new salary, the effective date and the reason, and produces a plain Word letter you can sign. For a change of role rather than pay, use the promotion letter; for the contract terms that sit behind it, see the offer letter guide.

General information, not legal advice. Pay review, consultation and discrimination rules differ by country and state.

Questions

Does a salary increase letter need to be signed?

A signature is not usually what makes the change effective, but a signed or acknowledged copy is strong evidence that the employee was told the new terms. Many employers ask for acknowledgement and keep it with the approval record.

Can an employer reduce a salary later?

In most places a reduction needs the employee's agreement or a contractual right, and may require consultation. A letter that says the salary is permanent can make a later reduction harder, so avoid promises you may need to revisit.

Should the letter mention the reason for the increase?

A short factual reason helps payroll, auditors and the employee understand the decision. It should not contain subjective comments about performance that you would not put in a formal review.
