Most loopholes exist for business owners. More deductions, breaks, and credits exist for business owners because business is the heart of our economy. By providing breaks to businesses, our government can stimulate the economy and keep it flourishing in times of good, and fuel it in recessions.
There is a common misconception that someone using tax planning or loopholes is a shady person, or someone practicing tax avoidance. The truth is that loopholes are created by the government. They want us to use loopholes. Loopholes are just government incentives to promote its public policy.
