Salary Increase Letter (Ireland)

A Salary Increase Letter in Ireland confirms the role, terms, or facts being offered or attested to and gives the recipient a written record they can rely on, under the framework of the Employment Equality Acts 1998-2015.

The Payment of Wages Act 1991 governs the payment of wages in Ireland and requires that wages be paid on time, in the agreed manner, and without unlawful deductions. The salary increase letter forms part of the contractual record of the employee's remuneration and provides clarity about the new salary level.

A salary increase may be granted for various reasons, including an annual cost-of-living adjustment, a merit increase following a performance review, a market adjustment to align the employee's salary with comparable roles, or a promotional increase in connection with a change of role. The letter should clearly state the reason, as this may be relevant to future salary negotiations or in the event of a dispute.

The salary increase will affect the employee's PAYE, PRSI, and USC obligations, and the employer should update the payroll accordingly. If the employee is a member of the employer's pension scheme, the increase may also affect pension contributions.

Under the Terms of Employment (Information) Acts 1994–2014, an employer is legally required to provide written notification of any change to the employee's terms of employment — including remuneration — within one month of the change taking effect. A salary increase letter satisfies this statutory obligation and confirms that the employer's payroll records, the employee's personnel file, and the PAYE Modernisation system maintained by the Revenue Commissioners are all updated consistently.

The National Minimum Wage Acts 2000–2015, as supplemented by the National Minimum Wage Order under the National Minimum Wage Act 2000, sets a statutory floor below which no employee's hourly rate of pay may fall. The Low Pay Commission, established under the National Minimum Wage (Low Pay Commission) Act 2015, recommends annual increases to the national minimum wage. The national minimum wage is EUR 13.50 per hour from 1 January 2025, increasing to EUR 14.15 per hour from 1 January 2026 following the Low Pay Commission's recommendation accepted in Budget 2026. Employers must confirm that any new salary — particularly following a salary review — continues to comply with the national minimum wage applicable at the relevant time, taking into account the employee's hours of work as recorded under the Organisation of Working Time Act 1997.

Where an employee's salary is governed by a Sectoral Employment Order (SEO) or an Employment Regulation Order (ERO) made under the Industrial Relations Acts, any salary increase must be at least consistent with the minimum rates specified in the applicable Order for the employee's grade or category. Failure to apply the minimum rates in an SEO or ERO constitutes a contravention of the Order and exposes the employer to enforcement action by the WRC.

From a payroll administration perspective, the salary increase letter provides the formal authorisation for the payroll function to update the employee's salary record in the employer's payroll software, to adjust the PAYE, PRSI, and USC deductions with effect from the stated date, and to reflect the new salary on the employee's payslip. Under the Payment of Wages Act 1991, every employee is entitled to a written payslip showing gross pay, all deductions made, and net pay. The first payslip following the effective date of the salary increase should clearly show the new gross salary amount.

An Irish Salary Increase Letter is needed whenever an employer grants an employee a salary increase, regardless of the reason for the increase or the amount involved.

You need a Salary Increase Letter when you are: awarding an annual cost-of-living or inflationary pay increase as part of the company's annual salary review cycle; granting a merit-based pay increase following a performance review or appraisal; adjusting an employee's salary to align with market rates following a benchmarking or salary survey exercise; increasing an employee's salary in connection with a promotion or expanded responsibilities; implementing a salary increase required by a collective agreement, sectoral employment order, or Employment Regulation Order under the Industrial Relations Acts; or correcting an underpayment or payroll error by issuing a formal notification of the correct salary.

The Terms of Employment (Information) Acts 1994–2014 impose a strict obligation to provide written notification of any change to remuneration within one month of the change taking effect. In practice, best employment practice is to issue the salary increase letter before or on the effective date of the increase, so that the employee is fully informed before the change appears on their payslip.

A salary increase letter is also important for payroll processing. The letter serves as the authorising document for the payroll department to update the employee's salary in the PAYE Modernisation system and to make the necessary adjustments to income tax, PRSI, and USC calculations. The employer must confirm that the new salary is reflected accurately in the payroll from the effective date and that the employee's payslip under the Payment of Wages Act 1991 shows the correct gross amount.

From a broader employment relations perspective, a salary increase letter is also a valuable tool for communicating the employer's appreciation of the employee's contribution and for reinforcing employee engagement and retention. Salary increases are among the most effective forms of employee recognition, and a well-drafted, personalised letter that explains the reason for the increase — whether it is a reward for exceptional performance, recognition of additional responsibilities, or an adjustment to reflect the current market rate — reinforces the positive nature of the communication.

Where the employer operates a formal annual pay review process, issuing salary increase letters consistently to all eligible employees — rather than communicating increases verbally or only through payslip changes — demonstrates good employment practice and helps the employer defend against potential complaints of unequal treatment or favouritism under the Employment Equality Acts 1998–2015. Maintaining a documented record of salary changes, the reasons for them, and the dates on which they took effect is also important for the employer's compliance with the GDPR and Data Protection Act 2018 obligations regarding the accuracy and completeness of employment records.

For employers who are party to a collective bargaining agreement or who recognise a trade union under the Industrial Relations Act 1990, salary increases may need to be implemented in accordance with the terms of the relevant Registered Employment Agreement or Sectoral Employment Order, and the salary increase letter should confirm compliance with the applicable agreement or order where relevant.

Under the Employment Equality Acts 1998–2015, an employer who grants salary increases in a discriminatory manner — for example, paying female employees less than male employees for like work — may be found to have committed unlawful pay discrimination under Section 19 (equal pay) of the Employment Equality Act 1998. The Workplace Relations Commission (WRC) adjudicates equal pay complaints, and the Labour Court hears appeals under Section 90 of the Employment Equality Act 1998. The National Minimum Wage Act 2000, as amended by the National Minimum Wage (Low Pay Commission) Act 2015, sets a statutory floor for hourly pay; the Low Pay Commission recommends increases to the national minimum wage, which is EUR 14.15 per hour from 1 January 2026. The Automatic Enrolment Retirement Savings System Act 2024 (My Future Fund) introduces mandatory pension contributions from 1 January 2026 for eligible employees aged 23–60 earning over EUR 20,000 per year. Revenue Commissioners administer PAYE, PRSI, and USC under the Taxes Consolidation Act 1997 and the Social Welfare Consolidation Act 2005. The Data Protection Commission (DPC) supervises the processing of employee salary data under the Data Protection Act 2018 and GDPR Article 9. Sectoral Employment Orders (SEOs) issued by the Labour Court under the Industrial Relations (Amendment) Act 2015 fix minimum rates of pay in certain sectors including construction, electrical contracting, and mechanical engineering.

A thorough Irish Salary Increase Letter should contain several essential elements to comply with Irish employment legislation and to provide clear documentation of the salary change.

The employer details should include the full legal name of the employer, the registered address and Eircode, and the name and title of the person issuing the letter on behalf of the employer.

The employee details should include the employee's full name, job title, department, and employee number. These details confirm that the letter is properly attributed and can be filed in the employee's personnel record.

The current and new salary clause should clearly state the employee's current gross annual salary and the new gross annual salary, both denominated in EUR. The clause should also state the payment frequency (weekly, fortnightly, or monthly) and confirm that the salary is subject to statutory deductions including income tax, PRSI, and USC.

The effective date clause should specify the exact date from which the new salary takes effect. Under the Terms of Employment (Information) Acts 1994–2014, the employer must provide written notification within one month of the change, so the letter should be issued promptly.

The reason for increase clause should state the reason for the increase, such as annual review, performance-related increase, market adjustment, or cost-of-living increase. This provides context for the employee and for the employer's records.

The pension and benefits impact clause should address any changes to pension contributions or benefits arising from the salary increase. If the employer operates an occupational pension scheme under the Pensions Act 1990, the letter should confirm whether contribution rates remain the same or are being adjusted. From 1 January 2026, the Automatic Enrolment Retirement Savings System Act 2024 (My Future Fund) phases in mandatory pension contributions for eligible employees aged 23–60 earning over EUR 20,000 who are not already in an occupational scheme — the letter should note whether the employee is enrolled in the auto-enrolment scheme and whether the new salary affects their contribution tier (initial rate: 1.5% employee, 1.5% employer, rising to 6% each by 2035).

The impact on bonus or variable pay clause, where relevant, should clarify whether the new base salary affects the calculation of any bonus, commission, or variable pay entitlement under the employment contract. Many performance-related bonus schemes are expressed as a percentage of base salary, so a salary increase will automatically increase the value of the bonus target.

The remaining terms confirmation clause should state that all other terms and conditions of the employee's employment remain unchanged unless expressly stated otherwise in the letter. This is particularly important to avoid any suggestion that the salary increase also represents a variation of other contractual terms.

The acknowledgement section should request the employee to sign and return a copy of the letter to confirm receipt and acceptance of the salary increase. The signed copy should be retained on the employee's personnel file as evidence of the written notification required under the Terms of Employment (Information) Acts 1994–2014.

The letter should be printed on company letterhead and signed by the appropriate manager or HR representative, with a date clearly stated. Where the employer is a company registered with the Companies Registration Office (CRO) under the Companies Act 2014, the company's registered name and CRO number should appear on the letterhead. The letter must be retained in the employee's personnel file under the employer's data retention obligations under the Data Protection Act 2018 and GDPR Article 5(1)(e), with the Data Protection Commission (DPC) supervising compliance. Under the Terms of Employment (Information) Acts 1994–2014, enforced by the Workplace Relations Commission (WRC), the employer must provide written notification of the salary change within one month; failure to do so entitles the employee to bring a complaint to the WRC under Section 7 of the 1994 Act. The Revenue Commissioners administer PAYE Modernisation under the Taxes Consolidation Act 1997 and require that the employer's payroll system reflects the new salary from the effective date through the Revenue Online Service (ROS). The Low Pay Commission, established under the National Minimum Wage (Low Pay Commission) Act 2015, recommends annual changes to the national minimum wage, which the employer must verify is not exceeded downward by the new salary when calculated on an hourly basis under the Organisation of Working Time Act 1997 working time records.
