Stockbrokers are versed in helping clients specifically invest and grow their wealth through the purchase of equities and other specific investment instruments that they represent. Accountants are able to give advice on taxes and tax strategies that can impact how much you must pay in taxes, what types of tax credits are available to you, and what you can do to limit your tax exposure in a given year. Insurance brokers are interested in selling policies to you, as a part of a larger investment strategy. Both stockbrokers and insurance brokers may earn commissions on what they recommend.
