Lowering your tax burden is more a function of changing how you live your financial life than preparing your taxes properly. The IRS smiles upon some activities (like marrying a stay at home parent, having children, getting a mortgage, giving to charity, earning a little bit of money, and saving for retirement) while frowning upon other activities (like marrying a high earner, investing in hard money loans in a taxable account, earning a lot of money, and buying expensive toys.) The largest tax break available to most attending physicians in their peak earnings years is maxing out their available tax-deferred retirement accounts.
