Filers under a certain amount
The largest group of people who don’t have to pay any income taxes are those who simply don’t make enough to make it worth it for the IRS to collect from them. If you work for an employer and are single with an income that is less than $9,350, then you do not need to even file your taxes, much less pay income taxes. If you are married, then this amount jumps up to $18,700 for your household. However, this is entirely different if you have self-employed income. In this case, you don’t need to pay any income tax, or even file, if the amount is less than $400.
An important thing to note is that these numbers are only applicable if you are under 65. If you are over 65, then there is another set of numbers that must be abided by. For those who fall into this category, then a single filer who makes less than $10,750 does not need to file or pay income taxes, while a married couple can make up to $20,900 before paying income taxes. The minimum amount for self-employed individuals over 65 remains $400, however.
The primary reason for these minimums is to provide some relief to individuals who are struggling, financially. However, another important factor is that it saves the IRS a reasonable deal of money in administrative costs, as the amounts required to work through the substantial percentage of returns that would be added would be unlikely to justify the cost. For this same reason, dependents (those who are younger than 19 or are full-time students up to the age of 245) are also not required to pay income taxes.
