<prompt> Human: I already have a job bringing 600 a week pre-taxes. The thing is, this is just enough to scrape by in my neighborhood even after making cuts along the line. I was trying to see how getting a second job would workout. Maybe bringing 440 a week pre-taxes. How will this affect taxes? Will my post-taxes income decrease as a whole or will it remain. I live alone and live for myself. Thanks in adnvanced.  <response>: Your post-tax income will increase. Tax bracket increases dont apply to your entire income; only the amount over the previous level. If you can get a second job, go for it!
