Manage Your Capital Gains Tax Bracket
Strategically timing capital gains realizations can optimize long-term capital gains taxation by managing applicable brackets and shifting gains to years with lower marginal rates.
Strategy Overview
Long-term capital gains tax rates are lower than ordinary income tax rates, but have a similar progressive taxation structure (i.e. the tax rate applied to long-term capital gains increases as your income/gains increase).
By understanding the long-term capital gains tax bracket thresholds and where your taxable income and capital gains will likely fall, you may be able to shift gains to a year with a lower applicable tax bracket.
Tax Details
Federal long-term capital gains tax rates increase with both your total taxable income and realized capital gains for the year. As such, strategically timing stock sales and/or using other strategies can help you manage your capital gains brackets to potentially lower applicable taxes. Key parts of the strategy include:
Intentionally delay sales of (at least some) stock to a future year when the incremental capital gains tax is anticipated to be lower. For many tech workers this would be optimizing for LTCGs to be taxed at the 15% bracket versus the 20% bracket (Capital Gains & NIIT Tax)
Maximize income tax deductions (e.g. contributions to retirement accounts, HSAs, etc.) to lower your taxable income. Because the long-term capital gains tax rate thresholds are crossed with income + capital gains, reducing your taxable income will provide a larger window for LTCGs at lower tax rates
Strategically utilize tax-loss harvesting to offset realized capital gains (and ideally keep gains in a lower LTCG tax bracket).
Manage your income tax bracket via strategies like deferring the exercise of NSO options to a future year (reducing income taxes and thus providing a larger window for LTCGs at lower tax rates)
Key Benefits
Reduce the long-term capital tax gains rate applied to your realized gains. Most commonly this allows individuals to reduce rates from 23.8% to either 15% or 18.8%. But in select scenarios, the reduction could be as large as 23.8% (e.g. from 23.8% to 0%).
Key Considerations/Flags
Investment risk. If you delay selling shares, you'll still have investment exposure/risk to the underlying company's stock price (and potential declines in value).
Can be complex to implement for concentrated positions with large embedded gains. When undertaking this strategy, we would recommend that you have a good understanding of tax lot management, and understanding/correcting cost basis Post-IPO for NSOs.
Strategy: When to Consider This and When to Avoid It
🟢 When to Consider This Strategy:
When you have a significant amount of stock with large embedded gains that will eventually need to be realized. Bonus points if you have other investments with embedded losses to pair together via tax-loss-harvesting
If you project being in lower ordinary income tax brackets in the future. All else equal, this will increase the amount of long-term capital gains you can realize at lower applicable tax rates
🔴 When to Not Use This Strategy:
You're not comfortable with (or concerned by) the investment risk associated with deferring the sale to the future
If you need cash (from stock sales) in the near term for major purchases or diversification. Holding periods defer access to funds
If it is difficult to accurately predict your future income, stock gains, and bracket impacts year-to-year. Unforeseen changes can disrupt planning.
If your gains are sizeable or your income is very large. Large gains in concentrated stock positions and/or high income anticipated for many years likely means you won't ever have an opportunity for much (if any) lower LTCG tax rates
