From IRS pub 501
If you are claimed as a dependent on someone else's return......
The Standard Deduction for an individual for whom an exemption can be claimed on another person's tax return is limited to the greater of:
…..$1,100 or
…..Your earned income for the year + $350 (but not more than 12,200)
So you would get a minimum of $1,100
See page 23 of Publication 501 and the worksheet on page 25
