Canada

The Canadian Taxpayers Federation is a shadowy nonprofit that has regularly worked to: • suppress native rights and claims • fight against gun legislation • fight against gas and oil taxes.
• fight against public health care

Also they are part of the Atlas Network, a global chain of right wing conservative "think tanks" that include such fantastic groups like the far right Fraser Institute that pushes to abolish public education and the Cato Institute that is literally one of the lobbying arms of the Koch group.

In the UK, if you're a sole trader(small business with no employees) or a VAT registered business, you have to either file taxes yourself, or pay someone else to do it for you. If you're an employee, you get a P60 from your employer, and they send one to HMRC, if you're not also pulling income from stocks, real estate etc, that's you done, and it's automatically calculated.

We should be more like the UK, and less like the US.

Here's an idea, the more complicated your taxes the more expensive it is to file. So most people pay nothing, but people who have the opportunity to scam the system have to pay enough to cover the people to investigate their filing.

I see no reason why the government can’t calculate your taxes based on your reported income and investments (and see if those numbers are plausible based on your location and occupation). Then if you want to challenge their numbers you can do your own return.

Are you guys American now??
