Forming an LLC or S-Corp for Crypto Trading: When It Actually Helps

The internet is full of advice to “trade inside an LLC to save on taxes.” Most of it is wrong. An LLC alone provides zero federal income tax benefit for crypto traders. What can help — under specific conditions — is the combination of Trader Tax Status (TTS), the IRC §475(f) mark-to-market election, and an S-Corp structure. Here is the honest analysis.

Trader Tax Status (TTS): The Gateway

TTS is not a formal election — it is a legal determination based on facts. A taxpayer qualifies for TTS when their trading activity is frequent, substantial, and carried out with continuity and regularity for the purpose of earning income. The courts and IRS look at:

• Number of trades per year (generally hundreds to thousands, not dozens)
• Total trading volume and frequency (several times per week, most weeks)
• Holding periods (mostly short, not long-term hold strategies)
• Time spent on trading activity (several hours per day)

Most buy-and-hold crypto investors do not qualify for TTS, regardless of their total portfolio value. TTS is for active traders who trade with the volume and frequency of a business. If you made 50 trades in a year, TTS is almost certainly not available.

“The number of people who actually qualify for Trader Tax Status is far smaller than the number of people who think they do. Before pursuing the §475(f) election or an entity structure, run the facts-and-circumstances test honestly.”

The IRC §475(f) Mark-to-Market Election

Traders who qualify for TTS can elect mark-to-market (MTM) accounting under IRC §475(f). Under MTM:

• All trading positions are treated as sold at FMV on December 31 each year
• All gains and losses are ordinary (not capital) — which means losses are not subject to the $3,000 capital loss limitation
• No wash-sale rules (§475(f) gains and losses are not capital, so §1091 does not apply)

The §475(f) election is powerful when you have large losses — converting capital losses (limited to $3,000/year of ordinary income offset) into unlimited ordinary losses. It is less useful if you primarily have gains, since ordinary income rates are higher than long-term capital gains rates. The election must be made by the due date of the prior year’s return (March 15 for S-Corps, April 15 for individuals) and is largely irrevocable.

Payroll Tax Savings via S-Corp: The Real Math

An S-Corp saves on self-employment / payroll tax only when the entity has net income subject to those taxes. Here is the logic:

• A sole proprietor or single-member LLC with TTS and §475(f) pays SE tax on net trading income
• An S-Corp splits that income into a “reasonable salary” (subject to payroll tax) and S-Corp distributions (not subject to payroll tax)
• If reasonable salary is $80,000 and distributions are $120,000, you save approximately 15.3% × $120,000 = ~$18,000 in SE/payroll tax — minus payroll administration costs ($2,000–$5,000/year)

The savings are real but require the entity to have net Schedule C income. Capital gains (from investments, not trading business) do not flow through an S-Corp with SE tax savings — they remain capital gains on the individual return regardless of entity structure.

When an LLC Alone Does Nothing

A single-member LLC is a disregarded entity by default. For federal income tax purposes, it does not exist — all income and loss flows through to your Form 1040 exactly as if there were no LLC. An LLC does not convert capital gains to ordinary income or vice versa. It does not enable deductions unavailable to an individual. The only federal tax benefit of an LLC is the ability to elect S-Corp treatment — and that benefit requires TTS and §475(f) to be meaningful. The liability protection of an LLC is a non-tax consideration, but it is not a tax strategy.

Costs and Breakeven Analysis

S-Corp formation and ongoing administration costs approximately $3,000–$6,000 per year in accounting and payroll fees, plus state formation fees. The breakeven point — where SE tax savings exceed these costs — is typically around $60,000–$80,000 of net self-employment income from trading. Below that level, the S-Corp structure is likely a net cost. See our pricing page for Chainblock’s entity advisory engagements and annual S-Corp packages.
