<prompt> Human: My brother recently moved to the US LA specifically with his wife and young child for a job that pays 100k, which seemed awesome. She cant work due to the visa and so all their money comes from him.Hes having a real tough time getting by and Im trying to help him. Hes mentioned hes paying 45 in tax ! which I hope is him misunderstanding something. Hes also going through some legal things due to problems at his first rented place.Based on he should have a gross income of 8333 and a net of 5780, which would be a loss of about 31 tax and medicare etc.Im trying to understand how your tax system works but its a bit complex! Are there things I might be missing that hed be paying more for, taxes Ive not considered also ones he might not have, are there things that might be issues at the end of the tax year??Also, are there any ways of paying less? Deductions, I think you call them. Does having a dependent count for some of that, or childcare?Finally, is there more information I can get that would help? Im not even really sure what to ask him.Sorry for lots of questions. Any advice, tips, warnings, etc. would be greatly appreciated. Edit - You people are awesome.So, key things learned so far:There are deductions, which should be on a form called a W-4, which if hes not filled out correctly for having 2 dependents he could be overpaying by quite a bit.45 sounds high, although if that figure includes 401k, health insurance, maybe other things, then its possible but sounds like its worth checking out if hes not filing properly.If he is overpaying he can get it back, but we have to be quick as the tax year is almost over.  <response>: 100k is not high for L.A. but it is far more than enough to get by. Most people get by with a lot less. Quick google search shows that the median household income in L.A. is around 60k.
