Things have gotten tough for this country. It has never been harder to find a job, pay your bills, and support your family. This is why more people are not paying all of the taxes they owe. This can lead to a lot of outcomes, but doing nothing will ensure the worst situation possible.
Income tax became a permanent part of our tax laws when the 16th amendment was added to the constitution in 1913. Since then, it has simply been a fact of life that part of your paycheck goes to the government. If you fail to do this completely, one penalty you may face is an IRS garnishment. This is when the government takes money directly out of your paycheck in order to satisfy your debt. However, they will not do this without first giving you notice as well as an opportunity to make other arrangements for payment.
