The Tax Map of Your Net Worth: Which Accounts Get Taxed How

The number on your balance sheet is a lie

Not a big lie, and not an intentional one, but a lie nonetheless.

When you look at your net worth (the total of every bank account, brokerage, retirement fund, property, and business interest you own, minus everything you owe), you're looking at a number that assumes you could access all of it, right now, at face value.

You can't.

The IRS has a claim on a significant portion of your wealth, and the size of that claim depends entirely on which accounts hold the money. A dollar in a Roth IRA is worth more than a dollar in a traditional 401(k), which is worth more than a dollar in a short-term brokerage gain. Same dollar, but very different after-tax values.

Understanding this is the difference between thinking you have $2 million and actually having $2 million.

Most people never think about this until they start withdrawing money, whether in retirement, during a sale, or in an emergency. By then, the tax bill is a surprise, and surprises in tax planning are always expensive.

Why this matters now, not later

You might be thinking: "I'm not retiring for 20 years. Why should I care about the tax treatment of my accounts today?"

Because the decisions you make today (which accounts you contribute to, which investments you hold where, when you harvest losses, when you convert) compound just like your investments do. A small tax-inefficient decision repeated over 20 years becomes a six-figure mistake.

And because you track your net worth (you do track it, right?), you're already in the habit of looking at the full picture. This article adds a new lens to that picture: the after-tax lens.

Let's walk through every major account type on your balance sheet and understand exactly how each one gets taxed.

Pre-tax retirement accounts (Traditional 401(k), Traditional IRA, 403(b), 457)

These are the accounts most people contribute to first, often through an employer match. The tax deal is simple: you get a deduction today, and you pay ordinary income tax on every dollar you withdraw later.

That "later" part is where people get surprised.

If you have $800,000 in a traditional 401(k) and you're in the 24% federal tax bracket in retirement, that $800,000 is really worth about $608,000 after federal taxes. Add state income tax (which varies from 0% in Texas and Florida to 13.3% in California) and the real number shrinks further.

Key tax rules:

• Withdrawals are taxed as ordinary income (your marginal tax rate, not capital gains rate)
• Required Minimum Distributions (RMDs) start at age 73 (75 starting in 2033)
• Early withdrawals before 59½ incur a 10% penalty plus ordinary income tax
• Contributions reduce your taxable income in the year you contribute

What this means for your net worth: When you see $800,000 in traditional retirement accounts on your balance sheet, the after-tax reality is closer to $560,000-$640,000 depending on your state, a 20-30% haircut that most people never account for.

Roth accounts (Roth IRA, Roth 401(k))

Roth accounts are the mirror image of traditional accounts. You contribute with after-tax dollars (no deduction today), but withdrawals in retirement are completely tax-free.

That means a dollar in your Roth IRA is worth a full dollar, with no haircut, no future tax bill, and no RMDs (for Roth IRAs; Roth 401(k)s had RMDs until SECURE 2.0 eliminated them starting in 2024).

Key tax rules:

• Qualified withdrawals (age 59½ + account open 5 years) are 100% tax-free
• Contributions can be withdrawn at any time, tax and penalty-free
• No Required Minimum Distributions for Roth IRAs
• Growth is never taxed if withdrawn after qualification

What this means for your net worth: Your Roth balance is the one number that means exactly what it says. If your Roth IRA shows $200,000, you have $200,000. This is why building Roth assets, whether through direct contributions or Roth conversions, is one of the most powerful long-term wealth strategies.

Taxable brokerage accounts

Your standard brokerage account (the one that isn't inside a retirement wrapper) has the most nuanced tax treatment. The tax you owe depends on what you hold, how long you've held it, and whether you sell.

Capital gains:

• Long-term (held over 1 year): Taxed at 0%, 15%, or 20% depending on your income. Most people pay 15%.
• Short-term (held under 1 year): Taxed as ordinary income. For high earners, this can be 32-37%.
• Net Investment Income Tax (NIIT): An additional 3.8% surtax on investment income for individuals earning over $200,000 ($250,000 married filing jointly).

Dividends:

• Qualified dividends: Taxed at long-term capital gains rates (0%, 15%, or 20%)
• Non-qualified dividends: Taxed as ordinary income

Unrealized gains, the hidden factor: Here's the part most people miss. If your brokerage account shows $500,000, but your cost basis (what you originally paid) is $300,000, you have $200,000 in unrealized gains. If you sold everything today at the 15% long-term capital gains rate, you'd owe approximately $30,000 in tax.

So that $500,000 is really worth about $470,000 after tax. Not a massive difference, but it scales. At $2 million with $1 million in gains, you're looking at a $150,000+ tax bill.

What this means for your net worth: The after-tax value of a brokerage account depends on your unrealized gains. A recently funded account with small gains is worth close to face value. A decades-old account with massive appreciation might be worth 10-15% less than the balance shows.

Real estate

Real estate is where the tax code gets genuinely complicated, and genuinely generous, if you know how to use it.

Primary residence:

• Up to $250,000 in gains excluded from tax when you sell ($500,000 for married couples)
• Must have lived in the home for 2 of the last 5 years
• This is one of the most powerful tax breaks available to individuals

Rental properties:

• Rental income is taxed as ordinary income
• But you can deduct depreciation: the IRS lets you write off the value of the structure (not the land) over 27.5 years, even though the property may be appreciating in value
• Depreciation recapture: When you sell, the depreciation you claimed is "recaptured" and taxed at 25%. This is the tax bill that surprises most real estate investors.
• Gains above your depreciated basis are taxed at capital gains rates (15-20%)

The 1031 exchange loophole: You can defer all capital gains and depreciation recapture taxes by exchanging one investment property for another through a 1031 exchange. Do this repeatedly over a lifetime, then die, and your heirs get the step-up in basis, potentially erasing decades of deferred gains entirely.

What this means for your net worth: The after-tax value of real estate is highly variable. Your primary residence is likely worth close to face value (after the exclusion). A rental property with years of depreciation and appreciation has a complex tax position that depends on your exit strategy.

Business equity

If you own a business, or a share of one, the tax treatment of that equity depends on your entity structure and how you eventually monetize it.

Sole proprietorships and partnerships:

• Income is "passed through" and taxed as ordinary income
• Subject to self-employment tax (15.3% on the first ~$184,500, 2.9% above that)
• The 20% Qualified Business Income (QBI) deduction can reduce the effective rate significantly

S-Corps and C-Corps:

• S-Corp profits pass through to your personal return (ordinary income rates, but only reasonable salary is subject to payroll tax)
• C-Corp profits are taxed at the corporate level (21%) and then again when distributed as dividends (double taxation)
• Qualified Small Business Stock (QSBS) exclusion: if your C-Corp qualifies, up to $10 million in gains (or $15 million for stock issued after July 4, 2025) can be completely tax-free on sale

On sale of the business:

• Asset sales vs. stock sales have very different tax implications
• Long-term capital gains rates apply if you've held the equity for over a year
• Installment sales can spread the tax hit over multiple years

What this means for your net worth: Business equity is the hardest asset to tax-adjust because the tax treatment depends on the entity type, your exit strategy, and timing. A rough rule: assume 20-30% of the value will go to taxes on sale, unless you have specific planning in place (like QSBS or an installment sale).

Health Savings Accounts (HSAs)

The HSA is the only triple-tax-advantaged account in the entire tax code:

1. Contributions are tax-deductible (like a traditional 401(k))
2. Growth is tax-free (like a Roth)
3. Withdrawals for qualified medical expenses are tax-free (like neither)

If you use your HSA as a long-term investment vehicle by paying medical expenses out of pocket now, investing the HSA funds, and withdrawing tax-free decades later with saved receipts, it's arguably the most tax-efficient account that exists.

After age 65, HSA withdrawals for any purpose are taxed as ordinary income (like a traditional IRA) with no penalty. So even if you don't have medical expenses, it's no worse than a traditional retirement account, and for medical expenses, it's strictly better than everything else.

What this means for your net worth: An HSA dollar earmarked for medical expenses is worth a full dollar (tax-free withdrawal). An HSA dollar used for non-medical spending after 65 is worth roughly the same as a traditional IRA dollar.

529 education savings accounts

529s offer tax-free growth and tax-free withdrawals when used for qualified education expenses (tuition, room and board, books, and up to $20,000/year for K-12 expenses including tuition, books, tutoring, and testing fees).

• Contributions are made with after-tax dollars (but many states offer a state income tax deduction)
• If used for non-qualified purposes, earnings are taxed as ordinary income plus a 10% penalty
• Unused 529 funds can now be rolled into a Roth IRA for the beneficiary (up to $35,000 lifetime, as of SECURE 2.0)

What this means for your net worth: If the money will be used for education, it's worth face value. If not, factor in the penalty and tax on earnings.

Putting it all together: your after-tax net worth

Here's a simplified example. Say your balance sheet looks like this:

That's a $240,500 gap (about 13%) between your stated net worth and your after-tax reality. For some people with heavy pre-tax retirement accounts or large unrealized capital gains, the gap can be 20-25%.

What to do with this information

You're not going to restructure your entire financial life overnight based on one article. But here are the highest-leverage moves:

1. Maximize Roth contributions and conversions. Every dollar you move from pre-tax to Roth (at a tax rate you're comfortable with) increases the after-tax value of your net worth. Look for low-income years (job transitions, sabbaticals, early retirement) as conversion windows.

2. Hold tax-inefficient assets in tax-advantaged accounts. Bonds, REITs, and high-dividend stocks belong in your IRA or 401(k). Growth stocks with low dividends belong in your taxable brokerage (to take advantage of long-term capital gains rates and the step-up in basis).

3. Harvest losses annually. If you have losing positions in your taxable accounts, sell them to realize the loss, then reinvest in a similar (not identical) fund. Those losses offset gains and reduce your tax bill. Up to $3,000 in net losses can offset ordinary income each year, with the rest carrying forward indefinitely.

4. Plan real estate exits in advance. If you own rental property, map out your 1031 exchange options before you're ready to sell. The 1031 timeline is strict (45 days to identify replacement property, 180 days to close), and scrambling at the last minute leads to bad deals or missed opportunities.

5. Review your entity structure. If you have business equity, make sure your entity type is optimized for your tax situation. The difference between an S-Corp and a sole proprietorship can be tens of thousands per year in self-employment tax alone.

6. Track your cost basis. For your brokerage accounts, know your unrealized gains. This lets you estimate the tax impact of any potential sale and make smarter decisions about which lots to sell first (specific identification method vs. FIFO).

The next time you open your balance sheet and see your net worth number, you'll know what it really means, and more importantly, what you can do to close the gap between the stated number and the after-tax reality.

That's the kind of clarity that compounds.
