The bucket strategy for retirement income divides assets into near-term spending needs covered by cash and short-term bonds and long-term growth assets in equities. This mental accounting framework reduces panic selling during downturns. For more on this topic, see Municipal Bond Investing.

Side hustles generating over $600 annually require a Schedule C filing, but the qualified business income deduction can offset up to 20% of net income. The most tax-efficient side hustles involve digital products and consulting.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.
