If your circumstances change you should tell the Revenue Service as soon as possible - if you do not, you could pay too much tax, or get a tax bill at the end of the year.
Changes you should tell us about include:
If your income changes
- Changes in your income can affect the amount of tax you pay and the earlier you tell us, the sooner we can update your details to make sure you pay the right amount.
- This could include:
- Employment changes including starting work for the first time or taking on additional jobs
- Starting to receive new income such as a personal, occupation or old age pension, money from self-employment, rent from property or casual earnings that are not taxed at source
- Major changes to your investment income or your bank interest increasing above £50
- Your income increasing to £100,000 or more as this may affect your personal and other tax allowances
- Update your income
- You can check and update the income included in your Coding notice Online. For the current calendar year, you can:
- To check and update your income online, you need a MyGov personal account user ID and password. If you do not have a user ID, you can create one when you first update your income.
- If you cannot use these services, you can contact the Revenue Service to advise of changes to your income or get help from an accountant.
If you're leaving Guernsey
- Tell the Revenue Service you are leaving Guernsey, Alderney or Herm by completing a leaving Guernsey Form.
- You will also need to provide your forwarding address, a copy of your final payslip and other information if requested so that we can update your details before you leave.
If you're coming to live in Guernsey
If you're buying a property
- Tell the Revenue Service you're buying a property by completing a Buying Property Form.
- If the property you're buying is in Guernsey and you will occupy this as your only residence, this is known as your principal private residence (PPR). You may be able to claim for relief on mortgage or loan interest paid on your PPR. Full details of the rules for relief on interest paid can be found in the Income Tax (Tax Relief on interest payments) Guernsey Ordinance, 2007.
If you've changed address
- You can use the Tell Us Once service to update your postal address with most government services.
If you get married or form a civil partnership
- Tell the Revenue Service you have married or entered into a civil partnership by completing a Notification of Marriage Form.
- Separate tax returns must be completed for the year you marry and an assessment will be issued to each of you individually.
- The tax returns that are submitted in the years following will be made by the husband in an opposite-sex marriage, or the eldest spouse in a same-sex marriage, and must include income from both spouses unless you have requested to be separately assessed, in which case, you will continue to complete separate returns.
If you divorce, separate or stop living with your husband, wife or partner
- Tell the Revenue Service you have separated by completing a Notification of Separation Form.
- For tax purposes, the separation date required is the date you stopped living together as a married couple and not the date of your legal separation.
- A new Coding Notice will be issued to you which will reflect your change in circumstance and your income tax affairs will be kept separate from this date.
If someone passes away
- When someone dies you should let us know as soon as possible.
