You need to notify the Revenue Service each time you change your job. The easiest way to do this is using the following online form.
Before you start
This service is available for residents of Guernsey and Alderney unless you currently:
- Have more than one job
- Earn more than £90,000 each year
- Are self-employed
- Are leaving work (if you are retiring)
- Have changed your circumstances, (you have got married, divorced or bought a property with a mortgage)
- Are a student
If you fall into any of these categories, please email us at checkmycoding@gov.gg or phone us on 225700.
Information you will need
- Your Social Insurance number: You can find this on your Insurance card or on the new type of Coding Notices
- Your Tax Reference number: You can find this on your most recent Coding Notice
- Your new employer's name: This can be either a company/business name, trading name or the personal name of the employer (If you are unsure, check with them)
Complete the form: Change of Employment - States of Guernsey (gov.gg)
The Revenue Service will process any personal data that you provide, via this online platform, in accordance with the Data Protection (Bailiwick of Guernsey) Law, 2017. Further information about how your personal data is processed by the Revenue Service can be found here.
What happens next?
- After we have received your notification, we will send you a new Coding Notice. This will contain information about the allowances you are entitled to, and any income you receive which is not taxed at source. It will also show your calculated Tax-free Coding Balance, (which is the amount your employer will deduct from your salary figure, after any payments have been made to an approved pension fund, to calculate the figure on which tax needs to be deducted).
- Your new employer will also receive notification of your Tax-free Coding Balance so that they can calculate the tax you need to pay tax on your salary.
