Chief of the Defence Staff Jonathan Vance has launched a wide-ranging review of the rules around tax-free status for military personnel, after troops in Kuwait lost a tax break because officials said they didnā€™t face a high enough risk.

At the top of Vanceā€™s list is making sure no more troops lose their tax exemption partway through deployment.

ā€œMy intent at this juncture is to try and avoid anyone losing this tax break while theyā€™re actually on operations,ā€ he said Friday.

Ā鶹“«Ć½ first broke the story that more than 300 Canadian Forces personnel in Kuwait were losing a tax break worth $1,500 to $1,800 a month, after the military downgraded the risk assessment of their mission -- even though some personnel regularly enter Iraq, where the Islamic State has a foothold.

The Chief of the Defence Staff said troops are supposed to receive a six-month warning if their tax status will be lost. But several military personnel in Kuwait told Ā鶹“«Ć½ they were not told in advance.

ā€œI didnā€™t know at all until I got on the ground,ā€ said one soldier who spoke to Ā鶹“«Ć½ on the condition of anonymity.

Vance hinted that those who already lost their tax break mid-tour in Kuwait could see a resolution.

ā€œThose who had planned on it ought to be able to get it,ā€ he said. ā€œSo weā€™re going to work on that and weā€™re going to try and put that in place.ā€

Critics say the government should expand tax-free status to more troops stationed in global hotspots.

Documents obtained by Ā鶹“«Ć½ show that Canadians serving in Bahrain, Qatar and Jordan -- where American and Jordanian security forces have been targeted in terror attacks -- do not receive a tax break, while U.S. soldiers stationed in those same countries are tax exempt.

ā€œCertainly, these are dangerous areas,ā€ said Christian Leuprecht, a professor of political science at the Royal Military College. ā€œIn Jordan, we have active efforts by militant groups inside the country.ā€

Even the mission in Erbil, Iraq, came up for review, after a risk assessment failed to qualify for automatic tax relief. On Friday, the finance ministerā€™s office said it expects Canadian troops in Iraq will keep their tax-free status.
