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. For more on this topic, see Tax Loss Harvesting.

Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.
