The Mark-to-Market (MTM) Election: A Double-Edged Sword

- ✅Wash Sale Exemption: Frees you from the complex wash sale rules, allowing for more flexible trading strategies and simpler accounting.
Cons
- ❌Ordinary Income Tax: All gains, including long-term holds, are taxed as ordinary income at higher rates, which is unfavorable for long-term investors.
- ❌Phantom Income: You must pay tax on unrealized gains at year-end, which can create cash flow problems.
- ❌Irrevocable Election: Once made, the election is permanent and cannot be revoked without IRS permission.
