Alternative minimum tax (AMT) is a system invented to make sure that higher income people with significant tax deductions didn’t avoid paying federal income tax. It uses a separate set of rules to calculate the tax owed after adding certain tax preference items back into adjusted gross income (AGI).  What you need to do is keep your AGI as low as possible through maximizing salary deferrals and pre-tax contributions to flexible spending plans and the like, keeping tax-efficient investments in taxable investment accounts, and taking all the tax credits of which you qualify.
