Common Mistakes

Missing election deadlines (83b: 30 days). Not capitalizing R&D properly (Section 174). Confusing AGI vs MAGI. Pro-rata rule on Backdoor Roth.

When to Use Strategy

Specific income thresholds + situation matter. Run scenarios. Consider multi-year tax projection. Don't optimize for ONE year only.
