In the United States there are not restrictions for money to be transfrered into a your corporation. However it should be properly documented within the minutes of the shareholder meeting. The infusion of capital can be either the purchase of stock or an officer's loan. If it is the purhase of stock it should be documented in the stock purchase ledger and stock certificated should be signed and given to you the stock buyer.. A stock purchase ledger comes with a corporate kit which is usually provided by the company or person that set up your corporation. If the infusion of capital is an officers loan, a written promisory note should be created and signed by the lender and borrower and stamped and signed by a notary. The note should charge interest and payments should be made on a monthly basis and interest should be charged. You the lended should receive a 1099 from your company if it pays you more that $600 for the year. The Corporation would expense the interest on the corpororation tax return and the lender (you) would put the interest received on their personal tax return. ***Note this is not legal advise or tax advise this is a general discussion of the topic.
