No worries.........There is no exact deducation % in the paycheck. It all depends upon various factors like, single or married, childrens, payrate, payamount, ur dependent, and many more.....

During OPT, there is not SSN and medicare tax . While in H1-B you have to pay these taxes. In few state, there is income Tax in top of it. The higher you make, the deductible % goes up. A person who makes 1000 in 2 weeks might have 100 as tax, BUT person who makes 3000 biweekly will have more than 3000 tax cut.

Anyway, all these should not matter, You will get all the tax return that you paid in excess at the end of the year. If you want less tax cut , just increase the dependent claimed. Put it 5, you can go upto 10 or 8 I think.

But, rember, you might end up paying at the end of the year, if u have paid less.

Did you file NR1040 or 1040 EZ or 1040?   ? While you were student.  Or did you got sitmuls rebate money??

If you answer this  I may be able to explain something.

Hello

I was in F1 Visa and started my OPT. In OPT you pay only Federal and State Taxes, We are exempted from Social Security and Medicare Taxes.

In my university, they recommended us to http://www.VisaTaxes.com

They specialize in tax preparation for visa holders in the United States.

Hope it helps!
