A general net-worth figure is a useful starting point—not automatically the proposal’s taxable wealth or your tax bill.
How do I calculate my net worth for a wealth tax?
Start with a dated inventory: net worth in the general sense is total assets minus debts and mortgages. The Congressional Research Service (CRS) describes wealth as assets such as stocks, bonds, real estate, and art, less liabilities; the IRS Statistics of Income uses a similar general definition. Neither definition, by itself, establishes which assets or debts a particular bill includes. Read the operative bill text for those rules.
Use this workflow to build an estimate:
- Identify the proposal. Record its jurisdiction, bill number, version, and current status. Find the provisions defining the taxpayer or tax unit, valuation date, included assets, debt deductions, exclusions, threshold, rates, and any reporting or valuation requirements.
- Determine the tax unit and ownership rules. Record individually owned, jointly owned, trust-held, and entity-held property separately. Apply the proposal’s rules for ownership and aggregation rather than assuming that all property in a household or trust is treated the same way.
- Build an asset ledger. For each holding, record its description, legal owner, treatment under the bill, value and valuation date, supporting evidence, and uncertainty. Include categories such as cash and financial accounts, traded securities, real estate, retirement assets, business and partnership interests, personal property and collectibles, and other intangible or contractual rights. The IRS wealth-statistics categories can help make the inventory broad, but do not replace the bill’s definitions.
- Value included assets on the required date. Keep statements and market-price records for traded holdings. For real estate and other difficult-to-value property, document the valuation method and evidence. If an uncertain value could materially change the result, consider a qualified appraiser or tax professional.
- Build a separate liability ledger. List mortgages, loans, liens, and other claimed debts with balances tied to the valuation date. Subtract only debts the proposal expressly allows.
- Calculate proposal-defined net wealth. Add the values of assets the bill includes, subtract permitted liabilities, and apply exclusions and special rules as written.
- Apply the threshold and rates. Check whether the threshold is a filing trigger, a deductible amount, or the start of a taxable slice. For brackets or surtaxes, apply each rate to the slice specified in the bill; do not multiply all net worth by a marginal rate.
- Show uncertainty honestly. If hard-to-value holdings could change the outcome, calculate a reasonable range and identify the assets driving it. Further appraisal or legal interpretation may narrow the range.
What assets count toward net worth?
The bill controls. A broad inventory is useful because a proposal may define assets differently from ordinary personal-finance measures or IRS statistical categories. Check each item against the actual definitions and exclusions rather than assuming it is included or exempt.
| Asset category | Practical valuation approach | What to document |
|---|---|---|
| Cash and financial accounts | Use balances on the bill’s valuation date. | Statements showing the account owner and dated balance. |
| Publicly traded stocks and bonds | Use market information for the specified date and method. | Account statements or price records for that date. |
| U.S. real estate | CRS notes that property-tax assessments or private market-value estimates may be used in wealth-tax designs; the bill determines the required method. | Assessment, appraisal, or other support for the value used. |
| Foreign real estate | CRS identifies added administration and verification difficulty for overseas property. | Ownership records and dated valuation evidence, with the method stated. |
| Privately held businesses and partnership interests | These can be difficult to value; use a method consistent with the bill and document assumptions. | Financial records, ownership share, valuation method, and uncertainty. |
| Collectibles and intangible assets | Art, wine, antique cars, jewelry, patents, and copyrights can be hard to value. | Ownership evidence and the basis for the estimate; consider an independent valuation if material. |
| Retirement assets and other rights | Check whether and how the proposal includes each asset type. | Account or contract records and the relevant bill provision. |
CRS says bank accounts and market-traded stocks and bonds are comparatively straightforward to value, but timing still matters because prices fluctuate. It also emphasizes that asset valuation is crucial to implementing a wealth tax. The valuation date specified in the proposal therefore matters: retain dated statements and valuation evidence rather than relying on a current balance for a different date.

Can I subtract my mortgage or other debts?
Not automatically. The general definition of net worth subtracts liabilities, but that is not a proposal-specific deduction rule. Check the bill for which debts qualify, how they are allocated to assets or owners, and what balance date applies. List each claimed liability separately and preserve records tying its amount to the valuation date; do not net it against an asset until the proposal’s rules allow that treatment.
How do I value a privately held business or other hard-to-price asset?
First check whether the proposal includes the asset and whether it prescribes a valuation date or method. Then record the method, evidence, assumptions, ownership share, and uncertainty. A public market price is not available for a private company, while collectibles and intangible property may also resist simple valuation. Overseas property may add verification and administration challenges. If the value could change whether or how much tax applies, professional valuation or tax advice may help; the final treatment still depends on the bill.

Which proposed wealth tax should I use?
There is no universal federal wealth-tax calculator established by the sources cited here. Congressional records describe introduced proposals, not one enacted set of rules that applies to everyone. The GovInfo record for H.R. 8316 describes a one-time tax on net worth above $10 million for certain individuals and trusts and records introduction and referral to House Ways and Means on April 15, 2026. That catalog description is not a substitute for the bill’s operative text.
The GovInfo record for S. 4246 identifies the introduced Ultra-Millionaire Tax Act of 2026 as a proposal to tax a taxpayer’s net value of assets and records referral to Senate Finance. For either proposal, consult the bill text and check its status; the record alone does not settle the rules needed to calculate an individual’s tax.
Recommended Free Tools
When comparing proposals, check the tax unit and aggregation rules, valuation date and method, included assets and exemptions, debt treatment, threshold and whether it is indexed, rate brackets or surtaxes, and reporting and audit provisions. Those design choices can change the taxable base and the result.

The Tax Policy Center (TPC) models alternative designs using assumptions about thresholds, rates, exclusions, avoidance, and behavior. Its 2025 estimates are scenario estimates, not official forecasts or personal calculators. For example, TPC estimated $1.9 trillion in revenue over 2025–2034 for a modeled 1% tax above $50 million ($25 million for unmarried individuals). It estimated $2.9 trillion over that period for a modeled two-rate design adding a 2% rate above $100 million. Those totals describe modeled revenue across the scenario, not what an individual would owe.
