A Nova Scotia resident's provincial tax is worked out on the NS428, attached to the federal return.
The rules (2026)
Brackets: 8.79% up to $30,995; 14.95% to $61,991; 16.67% to $97,417; 17.5% to $157,124; 21% above.[1] Credits are taken at 8.79%.
- Basic personal amount: $11,932.[2]
- Spouse or eligible dependant: $11,932 while the dependant's net income is $888 or less, then less each dollar above it, nil at $12,820.[3][4][5]
- Age amount: $5,826 at 65 or over, less 15% of net income above $30,828.[6]
- Pension amount: $1,173.[7] CPP and EI are credited as federally.[8]
- Young children: $100 for each month a child under 6 lives with the parent. In a couple, the parent with the lower income claims it.[9]
- Dividends: 8.85% (eligible) and 1.5% (other) of the grossed-up dividend.[10][11]
- Minimum tax: 57.5% of the federal additional tax.[12] Foreign tax is credited on the T2036.[13]
There is no surtax and no health premium.
Low incomes and seniors
The low income tax reduction starts from $300, adds $300 for a spouse (or, without one, an eligible dependant) and $165 for each other child at home, and is reduced by 5% of family income over $15,000.[14] A couple claims it once; the plan gives it to the spouse with the higher income.[15]
The age tax credit takes $1,000 off the tax of someone 65 or older whose taxable income is under $24,000. At that line it stops entirely.[16]
Someone 65 or older who received the Guaranteed Income Supplement in the year has their Nova Scotia tax refunded, up to $10,000.[17] The plan takes it off that year's tax.
After 2026
Nova Scotia indexes its brackets and its basic, spouse, dependant and age amounts. The age amount's income threshold, the pension amount, the young-children amount, the low income reduction and the age tax credit stay at the dollars in the statute.[18] The plan treats those like Ontario's two fixed thresholds: they grow with the plan's rate by default, and stay at their dollars if the plan is set to the law as written. See tax brackets after 2026.
What it does not do
The Poverty Reduction Credit, the Seniors Care Grant, the heating rebate and the seniors' property-tax rebate (each applied for) are not modelled. See also Nova Scotia benefits.
