What a $5,000 RRSP deduction saves in Nunavut at incomes from $30,000 to $250,000, the exact 2026 combined marginal rates, and the territorial rules behind each number.
A guide, not advice.
This page explains general rules. Do your own research, confirm your numbers with the CRA (your My Account and Notice of Assessment are the official record) or the other official sources listed at the end, and talk to a qualified professional before acting.
Nunavut taxes income in 4 territorial brackets (4%, 7%, 9%, 11.5%), with the top rate starting above $181,439. Combined with federal tax, the top marginal rate is 44.5% on taxable income over $258,482.
Nunavut has both the lowest first-bracket rate (4%) and the lowest top rate (11.5%) of any province or territory. Its basic personal amount is $19,659. At $70,000 a $5,000 RRSP deduction saves $1,375, the least of any province or territory, which makes the choice between an RRSP and a TFSA closer here than elsewhere.
Residents of prescribed northern zones, which include all three territories, can also claim the northern residents deductions on line 25500 of the return. The tables here start from taxable income, which is after that deduction, so look up your income after claiming it.
At $70,000 of taxable income, a $5,000 deduction saves $1,375 in Nunavut, which ranks 13 of 13 provinces and territories. The same deduction saves $1,858 in Nova Scotia and $1,375 in Nunavut.

The saving on $10,000 is rarely exactly double the saving on $5,000, because the second $5,000 comes off income that is taxed at whatever rate applies lower down. Usually that rate is lower, so each extra dollar is worth a little less. The biggest step up in value per dollar comes between $100,000 and $125,000, where the saving on $5,000 rises from 27.5% to 35% of the amount deducted.
RRSP refund estimator
Compares 2026 annual tax before and after your RRSP deduction, including bracket crossings, basic personal amounts, Ontario surtax and health premium, BC and Ontario tax reductions, and the Quebec abatement.
Use income after other deductions. Claim no more than your CRA RRSP deduction limit. The model assumes net income equals taxable income before this deduction. Savings reduce tax owing; your cash refund also depends on tax already withheld.
Deduction limit and other credits
Credit reductions are dollars of tax, not claim amounts, and stay fixed in both scenarios. In employment mode the CPP/QPP, EI, QPIP and Canada employment amount credits are already included, so enter only other credits here.

Nunavut tax starts from a $19,659 basic personal amount, credited at the lowest territorial rate of 4%.
Federal tax uses the 2026 federal brackets (14%, 20.5%, 26%, 29%, 33%) and a basic personal amount of up to $16,452, reduced for net income between $181,440 and $258,482.
A deduction is worth the most when it pulls income back below a point where the combined rate rises sharply. Between $25,000 and $260,000, the largest increases in Nunavut are:
$58,523: from 21% to 27.5%, because a new federal bracket starts.
$117,045: from 29.5% to 35%, because a new federal bracket starts.
$181,440: from 35% to 40.79%, because a federal and a territorial bracket both start here.
If your taxable income is a few thousand dollars above $181,440, for example, the first dollars you deduct are saved at 40.79%, and only the part of the deduction that takes you below $181,440 is saved at the lower 35%.
How these numbers are calculated
Each saving is the difference between two full 2026 tax calculations for a single filer with no dependants, before and after the deduction, using the federal and Nunavut basic personal amounts. It is a change in tax owed; whether you see it as a refund depends on tax withheld during the year. For what the estimate leaves out and how the deadline and limit work, see RRSP savings by province and the RRSP explained.
