Self Assessment (SA-102)

What is form SA102?

Form SA102 is used to report income from employment to HMRC. It includes details such as salary, wages, bonuses, commission, and any benefits received from an employer. Based on the information entered in this form, the software automatically calculates the individual’s correct tax liability.

If an individual has received forms P45, P60, or P11D, these documents provide the necessary information to complete the SA102 accurately.

What is P45, P60 and P11D? 

P45 Issued by an employer when an employee leaves a job. It shows the total pay and tax deducted up to the date of leaving.

P60: Issued by an employer at the end of the tax year. It summarises an employee’s total pay and deductions (including tax and National Insurance) for that year.

P11D: Issued by an employer after the end of the tax year to show the value of benefits and expenses provided to an employee (for example, company cars or private medical insurance).

What other information is required for Form SA102?

In addition to income details, an individual must provide:

• The employer’s name (and PAYE reference, if available).

• The date of leaving if employment has ended.

• If the individual was a company director, the date they ceased to hold that position must also be included.
