Crypto Tax Reality Calculator

This calculator projects hypothetical after-tax outcomes based on the inputs you provide. It uses simplified assumptions about tax timing and rates. Real outcomes depend on your specific tax situation, the assets you hold, when you sell, and rules that may change. Use this as a starting point for your own research, not a final answer.

Tax drag is the ongoing performance cost of holding taxable investments. If your fund or account generates dividends, interest, or short-term gains each year, you owe tax on those even if you did not sell anything. Over many years, that annual tax friction compounds into a significant gap versus an account that grows tax-deferred or tax-free.

Both are tax-advantaged account structures, but they work differently. A Roth-style account is funded with after-tax dollars. You get no upfront deduction, but qualified withdrawals in retirement are tax-free. A Traditional IRA or 401(k) is funded with pre-tax dollars, giving you a deduction now but requiring you to pay income tax on withdrawals later. Which is better depends on your current tax rate versus your expected rate at retirement. One significant difference beyond the basic math: Traditional IRAs require you to start taking minimum withdrawals at age 73, called required minimum distributions or RMDs. These are mandatory and taxed as ordinary income whether you need the money or not. Roth IRAs have no such requirement during your lifetime, which gives you full control over when and whether to draw down the account.

The higher an asset's return, the more painful annual taxation becomes. In a taxable account, you may owe capital gains taxes when you rebalance, receive distributions, or sell. Each taxable event pulls capital out of the compounding loop. Over a long time horizon with strong returns, those repeated reductions add up to a substantial difference compared to an account that compounds without interruption. High-income investors face a further layer: the Net Investment Income Tax adds 3.8 percent on top of capital gains rates for single filers with MAGI above $200,000 and for married couples above $250,000. This raises the effective federal capital gains rate to 18.8 or 23.8 percent for those investors, not 15 or 20 percent, and makes the advantage of tax-advantaged structures even more pronounced at higher income levels.

For 2026, the IRA contribution limit is $7,500 per person under age 50, or $8,600 for those age 50 or older under the IRS catch-up rules. This limit applies across all IRA types combined, meaning a $7,500 Roth IRA contribution leaves no room for a Traditional IRA contribution that year. A full Roth IRA contribution requires MAGI below $153,000 for single filers and below $242,000 for married couples filing jointly, with partial contributions allowed through $168,000 and $252,000 respectively. High earners above those thresholds can still access Roth benefits through a backdoor conversion. Traditional IRA contributions are not income-limited, but the deductibility of those contributions phases out at higher incomes for those covered by a workplace retirement plan. None of these limits are modeled in this calculator, which treats the monthly contribution amount you enter as fully investable regardless of account type.

No. The calculator works for any high-growth asset where tax treatment matters, including stocks, ETFs, or other assets held in taxable versus tax-advantaged accounts. Crypto is the primary use case because the return assumptions tend to be higher and the tax implications more dramatic, but the math applies broadly.

Because taxes reduce the amount compounding over time. In a taxable account, you may owe taxes on gains each year through dividends, distributions, or rebalancing. Every dollar paid in taxes is a dollar that stops compounding. Over 10 or 20 years, that drag adds up to a meaningful gap even if the underlying asset had the same annual return.

Tax drag is the performance cost of paying taxes on investment gains while still invested. It shows up as an annual percentage that effectively lowers your real return. For example, if your investment returns 18% but you owe taxes on dividends and distributions along the way, your net compound rate is lower. This calculator lets you set that drag rate to see its effect over time.

Because Traditional IRA withdrawals are taxed as ordinary income. You get a tax deduction when you contribute, but you pay income tax on every dollar you take out in retirement. The calculator uses your estimated retirement withdrawal tax rate to project that cost. The question is whether your retirement rate will be higher or lower than your current rate, which determines whether Traditional or Roth works better for you. There is also a rule specific to Traditional IRAs called required minimum distributions, or RMDs. Starting at age 73 (or age 75 for those born in 1960 or later, under the SECURE 2.0 Act), the IRS requires you to withdraw a minimum amount each year whether you need the money or not. Those withdrawals are taxed as ordinary income and can push you into higher brackets in retirement. Roth IRAs have no RMD requirement during your lifetime, which is one reason Roth structures are often preferred for long-term planning.

Because growth inside a Roth-style account is never taxed again. If an asset grows from $15,000 to $250,000 inside a Roth, you owe no tax on that $235,000 of gains at withdrawal. In a taxable account, those same gains would be subject to capital gains tax. The bigger the gain, the bigger the tax bill, and the bigger the advantage of a structure where that bill never arrives. One important qualification: to withdraw earnings from a Roth IRA completely tax-free, you generally need to meet two conditions at the same time. You must be at least age 59 and a half, and the account must have been open for at least five years. Your original contributions can always be withdrawn tax-free at any time regardless of age, but the earnings on those contributions require both conditions. If you are opening a Roth IRA for the first time today, the five-year clock starts now.

High earners above the income phase-out can still access Roth IRA benefits through what is commonly called a backdoor Roth conversion. For 2026, direct Roth contributions phase out for single filers between $153,000 and $168,000 in MAGI, and for married couples filing jointly between $242,000 and $252,000. Above those limits, no direct Roth contribution is allowed. The backdoor process involves making a non-deductible contribution to a Traditional IRA (which has no income limit) and then converting that amount to a Roth. The conversion is a taxable event, but if the Traditional IRA held no other pre-tax funds, there is typically little or no tax owed. This strategy is legal and widely used, but it has complexities depending on whether you hold other pre-tax IRA balances. This calculator does not model backdoor conversions. Consult a tax professional to evaluate whether this approach fits your situation.

Yes. The Net Investment Income Tax, or NIIT, is an additional 3.8 percent federal tax on investment income including capital gains from crypto. It applies to single filers with modified adjusted gross income above $200,000 and to married couples filing jointly above $250,000. These thresholds have not been adjusted for inflation since the tax was enacted in 2013, so more investors cross them each year simply due to wage growth. If you are in this income range, your effective federal capital gains rate is not 15 or 20 percent. It is 18.8 or 23.8 percent on your crypto gains. For high-growth scenarios, this meaningfully increases the after-tax cost of a taxable account and widens the advantage of a tax-advantaged structure. This calculator does not separately model the NIIT, but you can approximate its impact by entering a higher capital gains rate in the inputs.

As of 2026, the wash sale rule does not formally apply to cryptocurrency under current federal law. The wash sale rule prevents you from claiming a tax loss on stocks or securities if you buy a substantially identical asset within 30 days before or after the sale. Because the IRS classifies crypto as property rather than a security under current rules, this 30-day restriction does not apply to digital assets. That means crypto investors can sell a position at a loss to realize a tax deduction and immediately repurchase the same asset, which is not permitted with stocks. This is a meaningful planning consideration for taxable account holders managing crypto tax liability. However, legislation to extend the wash sale rule to digital assets has been proposed and could change. Do not rely on this treatment as permanent without confirming with a current tax professional.

No, and it is not designed to. This calculator uses simplified assumptions to illustrate the general tax impact of different account structures. For reference, the 2026 IRA contribution limit is $7,500 per person under age 50 and $8,600 for those age 50 or older, shared across all IRA types combined. Roth eligibility phases out for single filers between $153,000 and $168,000 in MAGI, and for married couples filing jointly between $242,000 and $252,000. Traditional IRA owners must begin required minimum distributions at age 73 (or 75 for those born in 1960 or later). The calculator also does not model income phase-outs, backdoor Roth conversions, early withdrawal penalties, state-specific tax treatment, the Net Investment Income Tax, or the specific deductibility rules that apply to Traditional IRA contributions based on workplace plan coverage. For planning that accounts for your actual situation, work with a qualified tax or financial professional.

No. This is a free educational tool that models hypothetical scenarios based on the inputs you provide. Nothing on this page is tax advice, financial advice, or a recommendation to open any specific account or make any investment. Results are estimates only. Tax rules are complex and change over time. Please consult a licensed professional before making decisions based on this or any other calculator.

At lower return assumptions, the gap between account types tends to shrink. Tax drag and capital gains tax have less impact when gains are smaller. Try adjusting the expected annual return slider down to see how the comparison changes. In lower-return scenarios, the taxable account sometimes comes close to or even matches the after-tax value of an IRA depending on your rates.
