Generally, each source of Retirement income may fit into one of three categories taxable account tax deferred account and tax-exempt accounts. When you retire you need to decide what money to use first. One approach to consider is to withdraw money from taxable accounts first then tax deferred and then tax exempt. By using taxable money first, you avoid paying taxes as long as possible with tax deferred investments and your tax-exempt accounts remain that way for a longer period. This is just one approach to consider.

Several factors such as your goals, time horizon, risk tolerance and tax situation may all play a role in determining the best approach for you.
