My parents have always claimed me as a dependent on their taxes even though I worked. Should i file all my previous taxes even though they claimed me?

Your dependency status has no bearing on the requirement to report all of your income to the IRS every year, regardless of your age. If you worked and received income, you are required to report that income to the IRS on a tax return, for the tax year you are paid that income. So if I understand you correctly, that means you have to file past year's tax returns for every year you had income.

And how old are you?  Were you a full time student?  You might not qualify as their dependent.  There are income limits.
