Northwest Territories tax refund calculator
What was withheld against what Northwest Territories and the federal schedule actually ask for.

| Income tax owed | $14,871 |
| Withheld | −$13,000 |
Withholding of about $14,871 would land you at zero. This compares income tax only — CPP and EI have their own ceilings and settle differently, so including them would give a figure that does not match your notice of assessment.
A refund is not a windfall
It is your money coming back. Every dollar of a refund is a dollar that was taken from a paycheque earlier than it needed to be, held for up to sixteen months, and returned without interest. The average Canadian refund is large enough that framing it as a prize is the most expensive piece of common sense in personal finance.
On $85,000 in Northwest Territories the income tax owed is $14,871. If $17,271 was withheld, the refund is $2,400 — which is $200 a month that was not in your account while you needed it.
The fix is not complicated: a new TD1 with your employer, or a request to the CRA to reduce withholding at source if you have deductions they can see coming — RRSP contributions, child care, support payments. Both move the money from April back into the year it was earned.
What actually creates a refund
Withholding built on the wrong assumption. Your employer withholds as though your current cheque describes your whole year. Start a job in September and the formula assumes you earned that rate for twelve months; you almost certainly over-paid.
Deductions the payroll never saw. RRSP contributions are the big one — they come off your income entirely and your employer does not know about them unless you say so. At a marginal rate of 29.10% in Northwest Territories, a $10,000 contribution is about $2,910 back.
Credits claimed on the return. Tuition, medical expenses, charitable donations and the disability amount are all applied when you file, not at source.
A balance owing usually comes from the reverse: more than one employer, self-employment income with nothing withheld, or investment income the payroll never touched.
Why this compares income tax only
The calculator above measures what was withheld against income tax owed, and leaves CPP and EI out of the comparison. That is deliberate, and it is what makes the figure match a notice of assessment rather than merely look plausible.
CPP and EI are not settled the same way. They have their own annual ceilings, and over-contributing to them — which happens if you change jobs mid-year — is refunded through a different line entirely. Adding them to a refund estimate produces a number that is wrong in an unfamiliar direction.
On $85,000 in Northwest Territories the income tax is $14,871 and the contributions are $5,770. Only the first of those two is what a refund is measured against.
How to stop lending the money
Two forms do it. TD1, the personal tax credits return, tells your employer which credits you are entitled to; filing an accurate one is the difference between withholding built on a default and withholding built on your situation. You file one federal and one provincial version.
Form T1213 goes further. It asks the CRA to authorise reduced withholding at source for deductions it can see coming — RRSP contributions, child care, support payments, employment expenses. Approved, it moves the money into your paycheque instead of your refund.
Neither is common, and that is the point: the default is to over-withhold, and the default is what most people leave in place. On $85,000 in Northwest Territories, withholding of about $14,871 lands at zero.
The one deduction that reliably creates a refund
An RRSP contribution comes off your income before either schedule touches it, so it saves tax at your marginal rate — 29.10% in Northwest Territories at $85,000. A $10,000 contribution is worth about $2,910 back.
Your employer does not know you made it unless you tell them, so it turns up as a refund rather than a bigger paycheque. That is the single commonest reason a refund exists, and unlike the other reasons it is one you chose.
The deduction does not have to be claimed in the year the contribution was made. Carrying it forward to a year when your marginal rate is higher is worth more — which is worth knowing before a year when you expect a promotion.
When the money actually moves
The filing deadline for most people is 30 April, and for the self-employed 15 June — though any balance owing is still due on 30 April, which is the trap in that second date.
A return filed online with direct deposit is usually assessed in about two weeks; on paper it can take eight. Either way the refund arrives long after the money left your paycheque: a dollar over-withheld in January comes back some sixteen months later.
Interest runs only one way by default. The CRA charges interest on a balance owing from 1 May; it pays interest on a refund only in narrow circumstances and only from a much later date. That asymmetry is the whole argument against treating a refund as a savings plan.
Where to go next
Questions
- How much tax should be withheld on $85,000 in Northwest Territories?
- About $14,871 of income tax over the year to land at zero. Withhold more and you get a refund; less and you owe. Your T4 box 22 shows what was actually taken.
- Is a big tax refund a good thing?
- No. It is an interest-free loan you made to the government. A $3,000 refund is $250 a month you did not have. Filing a new TD1 moves it back into your paycheque.
- Why do I owe money instead of getting a refund?
- Usually more than one employer — each withholds as if it were your only job, so neither withholds enough — or self-employment and investment income with nothing taken at source.
- Does this include CPP and EI?
- No, and deliberately. Those have their own ceilings and are settled on a separate line, so including them would give a figure that does not match your notice of assessment. On $85,000 they come to $5,770.
