Someone who lives at least six months in a prescribed northern zone deducts an amount for each day there when working out taxable income (line 25500). Yukon, the Northwest Territories and Nunavut are northern zones in full.[1]
The rules
$11 a day lived in the zone, and $11 more a day for keeping and living in a home there. Only one person in a home claims the second amount. The total is capped at 20% of net income.[2] The daily amounts are fixed in the statute: they grow with the plan's rate by default and stay put under the law as written.
In the plan
Every adult in the plan lives in the territory all year. Someone without a spouse claims both amounts; in a couple, the spouse with the higher net income claims the home amount.[3]
What it does not do
The travel part of the deduction is not modelled: it needs each trip and any travel benefit from an employer. The far north of six provinces and Labrador are northern zones too, but a plan only knows its province, so it takes no deduction there.
