8 Smart Ways to Shield Your Portfolio From Capital Gains While Doing Roth Conversions
(don’t forget to checkout the video of this blog too)
Roth conversions can be one of the most powerful retirement tax strategies available.
But there’s a catch…
If you’re not careful, your taxable portfolio can sabotage your conversion strategy by creating additional income through capital gains.
That extra income stacks on top of your Roth conversions — potentially pushing you into higher tax brackets, phasing out deductions, or even triggering Medicare IRMAA surcharges.
The good news?
With the right strategy, you can minimize these pitfalls and keep more money compounding for your future.
Here are 8 smart ways to shield your portfolio from capital gains while doing Roth conversions:
1. Rebalance Inside IRAs or 401(k)s
If you need to adjust your asset allocation, make those moves inside tax-deferred accounts instead of your taxable portfolio.
Why?
Because trades inside IRAs or 401(k)s don’t trigger capital gains.
That allows you to keep your taxable portfolio untouched — and your Roth conversion income cleaner.
2. Time Your Conversions Wisely
The best years to convert are often low-income years — before RMDs or Social Security benefits begin.
By timing conversions when you’re in a lower tax bracket, you maximize the efficiency of every dollar moved into your Roth.
3. Avoid Selling Appreciated Assets
Selling appreciated stocks or funds in a taxable account triggers capital gains, which stack on top of your conversion income.
If possible, delay selling appreciated assets until after your conversions are complete — ideally in years where your taxable income is lower.
4. Harvest Losses in Down Markets
When markets dip, you can sell underperforming assets in your taxable account to generate capital losses.
Those losses can offset capital gains elsewhere, and in some cases reduce your taxable income — giving you more room for Roth conversions at lower tax rates.
5. Use Non-Qualified Annuities
Non-qualified deferred annuities allow you to move appreciated assets into a tax-deferred wrapper.
That means no immediate capital gains hit.
Instead, the gains grow tax-deferred — giving you more flexibility to execute Roth conversions without interference.
6. Optimize Asset Location
Strategically placing assets in the right accounts reduces tax drag over time:
- Roth/IRA accounts → Growth-oriented or tax-inefficient investments (like REITs, actively managed funds, or high-yield bonds)
- Taxable accounts → Tax-efficient ETFs, municipal bonds, or Treasuries
This way, your taxable account generates less taxable income during conversion years.
7. Donate Appreciated Assets to Charity
If charitable giving is part of your plan, consider donating appreciated stocks instead of cash.
Through a Donor-Advised Fund, you:
- Avoid capital gains taxes entirely
- Potentially receive an immediate tax deduction
- Support causes you care about
8. Delay Realizing Gains Until After Conversions
Once your Roth conversions are complete, your taxable income will likely drop in retirement.
That’s the ideal time to sell appreciated assets — when you’re in a lower bracket and your conversions are behind you.
Bonus Tip: Use Tax-Advantaged Income Sources
Consider holding municipal bonds or U.S. Treasuries in your taxable account.
These generate income that is either tax-free or more favorable for federal tax purposes, which won’t interfere with your Roth conversion strategy.
Final Thoughts
Roth conversions are about more than just moving money from one account to another — they’re about managing your entire tax picture.
By shielding your portfolio from capital gains during conversion years, you can:
- Minimize tax drag
- Maximize income flexibility
- Protect your long-term legacy
That’s the essence of smart retirement income planning:
Keeping more of your wealth working for you and your loved ones.
