Roth “Bracket Filler” Tool
Find your optimal conversion amount based on 2026 IRS thresholds.
The “Tax-Free Growth” Logic: In 2026, a Roth conversion is treated as ordinary income. By “filling” your current bracket, you move money to a tax-free vehicle without paying a higher marginal rate than you do today.
Understanding the Basics
- Filling the Bracket: If you are $20,000 away from the top of the 12% bracket, you can convert $20,000 and pay only 12% on it. If you convert $20,001, that last dollar is taxed at 22%. This tool ensures you stop at the perfect Electric Lime Green limit.
- The 5-Year Rule: Remember that each 2026 conversion starts its own 5-year clock for penalty-free withdrawals of the principal. This tool helps you time your conversions to match your [Nomad Signal] lifestyle needs.
- Pay Taxes from the Outside: For maximum compounding, we recommend paying the conversion tax using cash from your Hybrid App profits rather than withholding from the conversion itself. This keeps more capital in the tax-free "Growth Snowball."

Frequently Asked Questions
1. Is it a good idea to convert while the S&P 500 is at 7,501? While you pay tax on the current "High" value, you are essentially betting that the market will be even higher in 10–20 years. If you expect your portfolio to continue its AI-driven growth, converting now ensures that all future gains are 100% tax-free.
2. Can I use my "Trump Account" for Roth conversions? No. Trump Accounts are for children's savings and have a $5,000 annual limit. However, the tax savings from these accounts can be used to pay the tax bill on your own Roth conversion.
3. What is the "Overtime Deduction" rule? If you are still working, the OBBBA allows you to deduct up to $12,500 (Single) or $25,000 (Joint) in qualified overtime pay. This lowers your taxable income, effectively creating more room for a Roth conversion in a lower bracket.
