Are you concerned that your partner is violating your agreement? Do you have any stock/ownership certificates showing your ownership in the S-Corp? Does the S-Corp engage in board/shareholder meetings? Do you have access to the books?
Generally, owners of a corporation are supposed to draw a reasonable salary. Is there an agreement in place (written, ideally) regarding your compensation? Obviously, if the business can't afford to pay a salary, then a salary is impossible. It's a business owner's hope that he or she will be paid for the work performed for his or her own company, but that is not always a reality. Your partner should be candid with you on what the finances of the business look like.
Further, owners/shareholders in a corporation have a fiduciary duty to each other. I would want to make sure everything is correct with the books and in good standing with the state and that everyone is in adherence to any agreements made between owners/shareholders. If not, I would suggest you contact an attorney regarding a possible breach of agreement and breach of his/her fiduciary duties.
Also, you may have a tax issue on your hands. You should've been issued appropriate tax documents (w2 or 1099) for the money you've received from the business. I do not concentrate in taxation, so I would contact an accountant or tax lawyer ASAP.
