Trader Tax Status and Section 475 Election Explained

If you’re trading actively, Trader Tax Status (TTS) combined with the Section 475 mark-to-market election is the most powerful tax strategy available to you. It changes how your trading income is taxed and unlocks deductions that ordinary investors can’t access.

What Is Trader Tax Status?

Trader Tax Status is an IRS classification that treats your trading activity as a business rather than an investment activity. This is significant because investors have limited deduction options, while businesses can deduct expenses on Schedule C.

The IRS doesn’t define TTS with a bright-line test. Instead, they evaluate whether you meet several criteria:

You trade frequently (typically hundreds of trades per year)
You trade on a substantially full-time basis
You seek to profit from short-term market movements, not long-term appreciation
Your trading activity is continuous and regular, not sporadic

There’s no minimum number of trades, but tax courts have generally looked for at least 720 trades per year (about 4 per day) as a strong indicator.

What Is Section 475 Mark-to-Market?

Section 475 is an IRS election that changes how you report trading gains and losses. Normally, traders report capital gains and losses, which are subject to the $3,000 annual loss limitation. With Section 475, your trading gains and losses become ordinary income and losses.

Why this matters:

No $3,000 loss cap. Ordinary losses fully offset other income without limitation
No wash sale headaches. The wash sale rule doesn’t apply to Section 475 trades
Year-end simplicity. All open positions are marked to market on December 31, so no need to track cost basis across years

The catch: you must elect Section 475 by April 15 of the tax year you want it to apply. You cannot make this election retroactively.

How to Qualify and Elect

Step 1: Determine if you meet TTS criteria based on your trading frequency, time commitment, and intent.

Step 2: File a statement with your tax return electing Section 475(f) mark-to-market accounting. The statement must be attached to your return for the year before the election takes effect, or filed with an extension.

Step 3: Going forward, report all trading activity as ordinary gains/losses on Form 4797 instead of Schedule D.

This is complex enough that you should work with a tax professional who specializes in trader taxation. Firms like GreenTraderTax and TraderStatus are well known in this space.

TTS Without Section 475

You can claim TTS without making the Section 475 election. This still gives you Schedule C business expense deductions (software, data feeds, VPS, education, home office) without changing how your gains and losses are reported.

Many traders start here and add Section 475 once they’re confident about their ongoing trading volume and activity level.

Work with a tax professional who specializes in trader taxation before making any elections

Frequently Asked Questions

Can prop firm traders claim Trader Tax Status? Possibly. If your prop firm activity meets the frequency and regularity requirements, you may qualify. However, prop firm income is typically 1099 contractor income, which is already treated as business income. TTS mainly helps personal account traders.

What happens if I elect Section 475 and then stop trading? You’d revoke the election by filing a statement with your return. Any open positions at the time of revocation would need to be handled according to the revocation rules. Consult your tax advisor.

Is there a downside to Section 475? Yes. Ordinary losses can offset other income (which is good), but ordinary gains are taxed at your regular income tax rate, which may be higher than the long-term capital gains rate. If you hold any positions longer-term, Section 475 could increase your tax on those gains.
