Hi everyone.  

My client is looking to live in the US... but work for (and obviously get paid by) a German business.   He will work remotely via computer in the US for about half of the month, then travel to Germany and work there for the other half of the month.

Apparently it may be a tricky, tax situation... so looking for an expert on this matter.

Any referrals or guidance would be appreciated.   Thanks.

Yes, there are tax implications and you want to consult with a CPA on this. Assuming your client is not a US resident/citizen, then he will be taxed as a US Nonresident Alien, and have to file Form 1040NR. The rules from there get very complex, as depending on his residency time in the US, the kind of income he will be having, etc. will influence the tax rates.
