tax between OPT and H1B

[micromysore]

What is the name of your state? CA

what are the differences in tax structure while a person is on H1B visa in comparisons to F1 visa.

some things i have noticed is
H1 - SSN tax, medicare tax
F1 - there is no SSN and medicare

apart from it what else is the difference ? If a person is earning the same amount while on F1 and on H1B.

also how to compute the taxes if the visa status was changed during the middle of the fiscal yr ?

A student on an F/J/M/Q visa is a nonresident alien for 5 calendar years, regardless of how many days they spend in the US. A nonresident alien cannot claim a standard deduction amount (usually) and often can't claim dependents.

A worker with an H visa is a resident for tax purposes when they have been in the US for 183 days. [To calculate days in the US, you add all the days present during the current year, 1/3 of the days from the prior year, and 1/6 of the days from the year before that.]

Usually, the year you switch from an F to an H visa, you are considered a dual status alien. Such fun for the tax preparer!
