Claiming tax relief for a child

​​Making a tax claim for a child

You can claim an increase in your tax exemption threshold and a standard rate deduction if you have a child who is:

  • ​under the age of 16
  • over the age of 16 and in full time education

The child must also be:

  • your child through marriage or civil partnership
  • your child born out of marriage, but you get married after the child's birth
  • your child who is resident with you
  • a legally adopted child
  • a step-child
  • a child that you have custody of and maintain at your own expense (this means the child lives with you, you have a say in the day to day care arrangements and you pay towards their upbringing)

If you need help filling out the child allowance section of your tax return watch our help video.

If you can claim a tax exemption increase for a child then you may also be able to claim an additional allowance in respect of children.

Restrictions to the tax relief or deduction

Child's income in own right

If the child you're claiming for is entitled to investment income or similar in their own right and that income exceeds £3,000 in the tax year, we'll reduce the deduction you can claim.

Two​​ or more people claiming for the same child

If more than one person can claim for the same child, the claim can be divided between you with a written agreement. 

​​If you can't agree, a statement of any direct expenditure in respect of the maintenance and education of the child must be provided by both parties to the taxes office. We will then review the claim in accordance with this information and give consideration to each person's entitlement under the Income Tax (Jersey) Law.

No entitlement to claim

Your claim will only be considered if you are entitled to make a claim for a child under the Income Tax (Jersey) Law. For example, you can't make a claim for a child who is not born through marriage and spends less than 90 nights with you in the year.

Making a claim for additional allowance in respect of children

​​​​If you are entitled to make a claim for a child then you may also be able to claim an additional allowance.

The child must be resident with you (their home is yours) to claim this allowance.

The other requirement is that you must match one of the following households:

  • single parent family
  • not be married, but living together as if husband and wife
  • not be in a civil partnership, but living together as if civil partners

If you are married or in a civil partnership, you can claim if your spouse or civil partner has been totally incapacitated by illness or disability during the whole of the year.

Amount of additional allowance

​2017 tax year​Additional tax allowance in respect of children
​Marginal rate exemption increase​£4,500 (max)
​Standard rate deduction​£1,500 (max)
Only one additional allowance is available per household or where two people claim for the same child.






For earlier years, refer to the relevant year of tax allowances and reliefs.

More than one claim for additional allowance

If more than one person can claim for the same child, the following rules apply.

Child resident with both you and another person for more than 90 nights in the year

The additional allowance can be divided between you with a written agreement.

If you can't agree, the allowance is split in accordance with the length of time the child is resident with each person making the claim.​​​​​

Child resident with you for less than 90 nights but more than 30 nights in the year

You can claim for part of the allowance based on the number of nights that the child stays with you if:

  • the other person who has the child living with them for the majority of the time agrees that you can claim
  • it does not affect their tax bill

You may also be asked to provide evidence that your home is also the child's home.

Child resident with you for less than 30 nights in the year

You can't make a claim for the additional allowance.
