Yes, you can add money to your IRA with either annual contributions or you can consolidate other former employer-sponsored retirement plan or IRA assets. Some people choose to make their annual contributions to their IRA so that they only have to keep track of one account. This may be right for you if you have no desire to roll these assets back to a qualified retirement plan at a future employer. Assets can be commingled and still be eligible to roll into another employer plan in the future; however, it is at the discretion of the receiving plan to determine what type of assets can be rolled over.
