Hi,

In 2006 I worked in the US with a J1 visa for 8 months and then I got a H1B visa from October to December. Am I supposed to pay the same amount of taxes with the J1 visa and the H1B visa?
Thanks

You should NOT be paying Social Security and Medicare taxes while under the J-1 visa.

However, your INCOME tax liability (state and federal) will be the same under both visas.
