New for 2023

The personal income levels used to calculate your Nunavut tax have changed.

The amounts for most territorial non-refundable tax credits have changed.

The Nunavut carbon credit has been introduced as a replacement for the Nunavut carbon rebate.

Nunavut benefits for individuals and families

To make sure you get your payments on time, you and your spouse or common-law partner need to file your 2023 Income Tax and Benefit Return(s) by April 30, 2024. The CRA will use the information from your return(s) to calculate the payments you are entitled to get from the following program:

Nunavut child benefit

The Nunavut child benefit (NUCB) is a non‑taxable amount paid monthly to qualifying families with children under 18 years of age. The territorial workers' supplement is an additional benefit paid to qualifying families who have children under 18 years of age. These benefits are combined with the Canada child benefit (CCB) into one monthly payment.

You do not need to apply for the NUCB. The Canada Revenue Agency (CRA) will use the information from your Form RC66, Canada Child Benefits Application to determine if you are entitled to receive the benefit.

Nunavut carbon credit

The Nunavut carbon credit (NCC) is a non-taxable amount paid to individuals and families to help offset the cost of the federal carbon pollution pricing levy. This amount is combined with the quarterly payment of the federal GST/HST credit.

You do not need to apply for the GST/HST credit or the NCC. The CRA will use the information from your return to determine if you are entitled to receive these credits.

The NUCB and the NCC are fully funded by Nunavut. For more information about these programs, call the CRA at 1‑800‑387‑1193.

Form NU428 – Nunavut Tax

Use this form to calculate your provincial taxes and credits to report on your return. Form NU428 must be completed after you have completed steps 1 to 5 of your federal income tax and benefit return.

Who should complete Form NU428

Complete Form NU428 if one of the following applies:

• You were a resident of Nunavut at the end of the year

• You were a non-resident of Canada in 2023 and any of the following applies:

  • You earned employment income only in Nunavut
  • You received income from a business with a permanent establishment only in Nunavut

Completing Form NU428

1. Fill out Part A – Nunavut tax on taxable income

   Calculate your tax on taxable income using the chart in Part A

2. Fill out Part B – Nunavut non-refundable tax credits

   The eligibility conditions and rules for claiming most Nunavut non-refundable tax credits are the same as those for the federal non-refundable tax credits. However, the amount and calculation of most Nunavut non-refundable tax credits are different from the corresponding federal credits.

   If you are a newcomer to Canada or an emigrant

   As a newcomer or an emigrant, you may be limited in the amount you can claim for certain territorial non-refundable tax credits.

   If you reduced your claim for any of the following federal amounts, you also need to reduce your claim for the corresponding territorial amount in the same manner:

   Corresponding federal and territorial non-refundable tax credits

   Federal amount on your return	Corresponding territorial amount on Form NU428
   line 30000	line 58040
   line 30100	line 58080
   line 30300	line 58120
   line 30400	line 58160
   line 30425	line 58200
   line 30450	line 58400
   line 31600	line 58440
   line 31800	line 58480
   line 32400	line 58600
   line 32600	line 58640

   You may also need to reduce your claim for line 58230 of your Form NU428 if you were a newcomer to Canada or emigrant in 2023.

   For examples on how to calculate these amounts, see Guide T4055, Newcomers to Canada.

   • Line 58120 – Spouse or common-law partner amount

     You can claim this amount if the rules are met for claiming the amount on line 30300 of your return and your spouse's or common-law partner's net income from line 23600 of their return (or the amount that it would be if they filed a return) is less than $17,925.

   • Line 58160 – Amount for an eligible dependant

     You can claim this amount if the rules are met for claiming the amount on line 30400 of your return and your dependant's net income from line 23600 of their return (or the amount that it would be if they filed a return) is less than $17,925.

   • Line 58200 – Amount for infirm dependants age 18 or older 

     You can claim up to $5,499 for each of your (or your spouse's or common-law partner's) dependent children or grandchildren born in 2005 or earlier who has an impairment in physical or mental functions.

     You can also claim this amount for more than one person if each one meets all of the following conditions:

     • They are your (or your spouse's or common-law partner's) parent, grandparent, brother, sister, aunt, uncle, niece, or nephew
     • They were 18 years of age or older
     • They were dependent on you (or on you and others) because of an impairment in physical or mental functions
     • They were a resident of Canada at any time in the year

     You cannot claim this amount for a person who was only visiting you.

     Parent

     A parent includes someone you were completely dependent upon and who had custody and control of you when you were under 19 years of age.

     Child

     A child includes someone who is completely dependent upon you for support and whom you have custody and control of, even if they are older than you.

     You can claim this amount only if the dependant's net income from line 23600 of their return (or the amount that it would be if they filed a return) is less than $13,303.

     If you had to make support payments for a child, you cannot claim an amount on line 58200 for that child unless both of the following conditions apply:

     • You were separated from your spouse or common-law partner for only part of 2023 because of a breakdown in your relationship
     • You did not claim any support amounts paid to your spouse or common-law partner on line 22000 of your return

     If both of these conditions are met, you can claim whichever of the following amounts is better for you:

     • line 58200 of your Form NU428
     • line 22000 of your return

     How to claim this amount

     Complete the calculation for line 58200 using Worksheet NU428. If you are claiming this amount for more than one dependant, enter the total amount on line 58200 of your Form NU428.

     The CRA may ask for a signed statement from a medical practitioner showing when the impairment began and how long it is expected to last. You do not need a signed statement from a medical practitioner if the CRA already has an approved Form T2201, Disability Tax Credit Certificate, for a specified period. The notice of determination will show which years you are eligible for.

     Claim made by more than one person

     If you and another person support the same dependant, you can split the claim for that dependant. However, the total amount of your claim and the other person's claim cannot be more than the maximum amount allowed for that dependant.

   • Line 58230 – Amount for young children less than six years of age

     You can claim this amount if you lived in Nunavut at the end of the year and you had a dependent child less than six years of age.

     You can claim $1,200 for each child if all of the following conditions apply:

     • The child was less than six years of age at any time in 2023
     • The child lived with you at the end of the year (or on the date of death for a child who died in 2023)
     • No one has received a special allowance under the Children’s Special Allowances Act for that child

     You cannot claim this amount if anyone made a claim for this child as an eligible dependant on line 58160.

     If you have a spouse or common law partner, only one of you can claim this amount. When both of you are eligible to make this claim, the person with the lower net income must make the initial claim. The other person may claim any unused amount by completing Schedule NU(S2), Territorial Amounts Transferred from your Spouse or Common Law Partner, and attaching it to their return.

     How to claim this amount

     Complete the chart "Details of amount for young children" on your Form NU428.

     Enter the number of children you are claiming on line 63710 of your Form NU428. Multiply this number by $1,200 and enter the total amount on line 58230 of your Form NU428

   • Line 58400 – Caregiver amount

     You may be able to claim up to $5,500 for each dependant if, at any time in 2023, you (alone or with another person) kept a dwelling where you and that dependant lived.

     Each dependant must be one of the following:

     • your (or your spouse's or common-law partner's) child or grandchild
     • your (or your spouse's or common-law partner's) brother, sister, niece, nephew, aunt, uncle, parent, or grandparent who was a resident in Canada

     You cannot claim this amount for a person who was only visiting you.

     Also, each dependant must meet all of the following conditions:

     • They were 18 years of age or older when they lived with you
     • Their net income in 2023 from line 23600 of their return (or the amount that it would be if they filed a return) was less than $24,283
     • They were dependent upon you because of an impairment in physical or mental functions, or they were your (or your spouse's or common-law partner's) parent or grandparent born in 1958 or earlier

     If you had to make support payments for a child, you cannot claim an amount on line 58400 for that child unless both of the following conditions apply:

     • You were separated from your spouse or common-law partner for only part of 2023 because of a breakdown in your relationship
     • You did not claim any support amounts paid to your spouse or common-law partner on line 22000 of your return

     If both of these conditions are met, you can claim whichever of the following amounts is better for you:

     • line 58400 of your Form NU428
     • line 22000 of your return

     How to claim this amount

     Complete the calculation for line 58400 using Worksheet NU428. If you are claiming this amount for more than one dependant, enter the total amount on line 58400 of your Form NU428.

     Claim made by more than one person

     If you and another person support the same dependant, you can split the claim for that dependant. However, the total amount of your claim and the other person's claim cannot be more than the maximum amount allowed for that dependant.

     If you or someone else is claiming the caregiver amount (line 58400) for a dependant, you cannot claim the amount for infirm dependants age 18 or older (line 58200) for that dependant.

     If someone other than you is claiming the amount for an eligible dependant (line 58160), you cannot claim the caregiver amount for that dependant.

   • Line 58440 – Disability amount for self

     You can claim this amount if the rules are met for claiming the amount on line 31600 of your return.

     If you were 18 years of age or older at the end of the year, enter $15,256 on line 58440 of your Form NU428.

     Transferring amounts

     • your spouse or common law partner (who would claim it on line 59090 of their Schedule NU(S2))
     • your parent or grandparent (who would claim it on line 58600 of their Form NU428)
     • your spouse's or common law partner's parent or grandparent (who would claim it on line 58600 of their Form NU428)

     If your spouse or common-law partner is claiming an amount for you on line 58120 or line 58640 of their Form NU428, you cannot transfer your unused tuition, education and textbook amounts for the current year to your (or your spouse's or common-law partner's) parent or grandparent.
