I worked 5 different jobs last year. Can I do multiple forms of tax returns to ensure I get a refund from those jobs?

NO, absolutely not.

You report, accurately, your income for the entire year, irrespective of if you worked for one employer or a dozen.

I'm sorry if I wasn't clear, but basically I'm going to get 5 different W2 forms from the 5 different jobs that I had last year. Should I wait for all the forms to come in or can I do them one by one is what I'm asking.

NO  You wait until you have ALL of them and put them on ONE tax return together.  If you try to file them one at a time you will create a train wreck with the IRS and for yourself.

I think what you are asking is if you can enter the W-2s "piecemeal" - 1 or 2 at a time as you receive them -  until all 5 show up.  The answer to that question is "Yes".  There's no need to enter all 5 at one sitting.  You can keep going back to the W-2 interview, entering W-2's as they show up.

(It did sound like you were asking if you could submit 5 different income tax returns, each one with only 1 W-2, in order to get ALL the taxes withheld refunded to you.)

That was my interpretation.

But what if the pay for one job is different from another? How will the deductions be calculated? I would think a document for each job would make more sense.

Here's an example:

I worked a contract job from April to June with a rate of $32/hr. Then I worked another contract job from June to December with a rate of $38/hr. Do I add all income at the end of the year by summing the numbers from the two separate W4s?

Your income and deductions are cumulative.  You enter your income from EVERY job separately on the SAME return.  So, if you get FIVE W-2's, you will go back and enter each W2 on the same return by clicking on Add another W-2.  

You are taxed on your income as a whole. All of your income is added together and all of your deductions are added together.

 This means if at each of your 5 jobs you made $12,000 and you had no other income, line 7b of your 1040 would be $60,000.  

Again, all of your income is to be accounted for on ONE 1040 form.  

yes you can enter each w-2 as you get it. but note all 5 W-2's get reported on the same return.
