Common Pitfalls
| Pitfall | Problem | Fix |
|---|---|---|
| Wash sale in IRA | Loss disallowed permanently | Never repurchase in IRA within 30 days |
| Ignoring NIIT | 3.8% surprise on high income | Factor into all capital gains calculations |
| Missing backdoor Roth | Leave tax-free growth on table | Execute every year regardless of income |
| Wrong asset location | Bonds in taxable, stocks in IRA | Flip it — bonds in tax-advantaged |
| Harvesting short-term losses only | Missing larger LT loss opportunities | Harvest all losses, note character |
| Forgetting state taxes | Federal only view misses true cost | Add state rate to all tax calculations |
| No Roth at young age | Miss decades of tax-free compounding | Open Roth IRA as soon as first income |
Best Practices
- Max retirement accounts first — guaranteed return equal to your tax rate
- Asset location before stock picking — location can add 0.5-1% annually
- Harvest losses systematically — review quarterly, not just December
- Backdoor Roth every year — even if you think income might drop
- Hold winners over 1 year — rate differential can be 20%+ difference
- Plan exits in advance — tax timing on large gains saves significant money
- Work with a CPA — tax law complexity makes professional help worth it
