Recently, Prime Minister Justin Trudeau announced several short-term initiatives related to tax policy. Most notably, the package includes a two-month GST holiday on certain items and a one-time $250 cheque that will be sent to all Canadians with incomes under $150,000.

Unfortunately, the Trudeau government’s package is a grab bag of bad ideas that will not do anything to get Canada out of the long-term growth rut in which our economy is mired. There are too many to list all in one place, but here are four of the biggest problems with Prime Minister Trudeau’s tax plan.

1. It reduces the wrong taxes. When it comes to economic growth, not all taxes are created equal. Some cause far more economic harm per dollar of government revenue raised than others. The government’s package creates a holiday on the GST for some items (only for two months) which is a mistake given that the GST is one of the least economically harmful components of the tax mix. Canada’s recent growth record is abysmal, and boosting growth should be a primary goal of any changes to tax policy. A GST cut of any duration fails this test relative to other tax cuts.
2. Temporary tax holidays shift consumption in time, they don’t boost growth. The government’s GST reduction is actually a short-term tax holiday on certain items that will last two months. There are decades worth of economic research showing that when governments create short-term tax breaks, they may change the timing of consumption, but they won’t contribute to actual economic growth. Shifting consumption from the future to the present won’t help get Canada out of the economic doldrums. This is particularly true of the Trudeau tax holiday since purchases that Canadians may have made after the two-month holiday period will simply be shifted forward to take advantage of the absence of the GST. As noted above, there are better taxes to cut than the GST, but no matter what taxes we are talking about permanent reductions are vastly superior to temporary tax cuts like short-term holidays.
3. One-time tax rebates don’t improve economic incentives. Perhaps the worst element of the Trudeau government’s announcement was a plan to send $250 cheques to all Canadians earning under $150,000. One-time tax rebates are a terrible way to provide tax relief. When you cut income tax rates, you improve incentives for people to work and invest because they get to keep a larger share of their earnings. This helps the economy grow. One-time rebates that you get regardless of the economic choices you make has no similar effect. This means that the rebate with its $4.7 billion price tag won’t help Canada’s poor growth performance.
4. It borrows from the future to give to the present. The federal government is currently running a large deficit. This raises the question of who will have to pay the $4.7 billion bill for the one-time payments announced today. The answer is that the government will have to borrow the money and therefore future taxpayers will have to either pay it off or service the extra debt indefinitely. The money the Trudeau government will send out won’t come out of thin air, it’ll have to be borrowed with the burden falling on future taxpayers.

The Trudeau government got one thing conceptually right, which is that there are advantages to reducing the tax burden on Canadians. Unfortunately, the policy package it has put forward to provide tax relief gets everything wrong. It reduces the wrong taxes, shifts taxes temporally rather than cutting them, does nothing to improve economic incentives, and burdens future taxpayers. With the holiday season around the corner, this attempt at a gift to Canadian taxpayers is the economic equivalent of a lump of coal in the stocking.
