After you file

And unfortunately, there's a chance it  could increase your tax by $12 or more.  It's very weird.

 

The tax tables look like this;

 

If your taxable income is at least but less than  Your tax is (single) Married filing jointly Married filing separately Head of household
53,450 53,500 7,382 6,006 7,382 6,124
53,500 53,550 7,393 6,012 7,393 6,130
53,550 53,600 7,404 6,018 7,404 6,136

 

 

What that means is that there will occasionally be a situation where someone's income is $53,499, and adding $2 of income raises their tax by $11.  Hopefully that doesn't happen if you add your extra $6.
