@rebmaboss , depends on the organizations policies. The only real difference fr you is that as a W-2, the entity withheld the taxes and Social Security / Medicare for you. Under the new arrangement, you are responsible to pay the US taxes and Self-employment taxes. You should consider paying US taxes quarterly ( estimated taxes). Social Security and Medicare taxes also may have to be paid depending your denomination and how it is registered ( vow of poverty etc. ). Note that if you meet the eligibility of foreign earned income exclusion then you may be able to exclude the income altogether from US taxes ( you may still have to pay medicare and social security ). Obviously you may have to pay taxes to your work country , depending on the tax laws there -- I am somewhat familiar with Brazil not not the other countries in SA.
