Quick Answer

The Section 475(f) Mark-to-Market election lets qualified traders deduct trading losses fully as ordinary losses, bypassing the $3,000 capital loss limit.

Key Rules

Ordinary Gain/Loss Treatment

All trading gains and losses are treated as ordinary income/losses instead of capital gains/losses. This means no $3,000 annual loss limit and no distinction between short-term and long-term holding periods.

Year-End Mark-to-Market

All open positions are treated as if sold at fair market value on the last business day of the tax year. Unrealized gains and losses are recognized and reported for tax purposes.

No Wash Sale Rule

The wash sale rule does not apply to Section 475(f) traders. You can sell at a loss and immediately repurchase the same security without any tax consequences from the wash sale rule.

Election Deadline

The MTM election must be filed by the due date of your prior year tax return (typically April 15) to be effective for the current year. The election is made by attaching a statement to your tax return and filing Form 3115.

Cannot Cherry-Pick

Once elected, all securities used in your trading business must be marked to market. You cannot selectively apply MTM to some positions and capital gains treatment to others within the same business.

Practical Examples

You have $80,000 in trading losses this year. Without MTM, you can only deduct $3,000 against income. With MTM, you deduct the full $80,000 as an ordinary business loss against all your income.

You hold AAPL overnight and repurchase after selling at a loss. Without MTM, this triggers a wash sale. With MTM, the wash sale rule does not apply and your loss is fully deductible.

On December 31, you hold open positions worth $15,000 in unrealized gains. With MTM, you must report these gains as if you sold on December 31, even though you still hold the positions.

Who This Applies To

US traders who qualify for Trader Tax Status (TTS) and elect Mark-to-Market accounting under IRC Section 475(f). This typically requires trading frequently, substantially, and continuously with the intent to profit from short-term price movements.

How JournalPlus Helps

JournalPlus supports MTM accounting by automatically marking all open positions to market at year-end and generating the required tax reports. It tracks your trade frequency and volume to help you document Trader Tax Status qualification. The MTM mode eliminates wash sale tracking since the rule does not apply, simplifying your tax preparation significantly.

What Is Mark-to-Market?

The Mark-to-Market (MTM) election under IRC Section 475(f) is one of the most powerful tax tools available to qualified active traders. It fundamentally changes how your trading gains and losses are reported for tax purposes.

Capital Gains vs Ordinary Income Treatment

Feature	Capital Gains (Default)	MTM (Section 475f)
Loss limit	$3,000/year	Unlimited
Wash sale rule	Applies	Does not apply
Holding period	Short/long-term	No distinction
Year-end positions	Not taxed until sold	Marked to market
Tax rate	Capital gains rates	Ordinary income rates

Who Should Elect MTM?

MTM is most beneficial for traders who:

Good Candidates

Trade frequently (hundreds or thousands of trades per year)
Have years with significant losses
Trade the same securities repeatedly (triggering wash sales)
Hold positions for short periods (days, not months)

Poor Candidates

Hold long-term investments alongside trading
Consistently profitable (losing long-term capital gains rates)
Trade infrequently (may not qualify for TTS)
Have large unrealized gains at year-end

Making the Election

The Process

Qualify for TTS - Establish your trading business meets IRS criteria
File by deadline - Attach an election statement to your prior year return by April 15
File Form 3115 - Application for Change in Accounting Method
Separate investment positions - Clearly identify non-business holdings
Report on proper forms - Use Form 4797 instead of Schedule D for business trades

The Election Statement

Your election statement must include:

Your name, address, and taxpayer ID
A statement that you are electing under Section 475(f)(1) for securities
The first tax year the election applies to
The trade or business for which the election is made

Year-End Mark-to-Market Implications

The most significant operational impact of MTM is the year-end recognition requirement. On December 31, all open positions are deemed sold at fair market value.

Planning Considerations

Unrealized gains become taxable - If you hold winning positions over year-end, the gains are recognized
Unrealized losses become deductible - Losing positions provide immediate tax benefits
New cost basis - Positions carried into the new year start with the December 31 fair market value as their new basis

Strategic Year-End Positioning

Some MTM traders deliberately close losing positions before year-end and hold winning positions. With MTM, this is unnecessary since everything is marked to market regardless. However, realizing losses before December allows for more accurate tax planning.

Record Keeping Under MTM

Even though MTM simplifies some aspects of tax reporting (no wash sale tracking, no holding period monitoring), you still need:

Complete trade records with dates, quantities, and prices
Year-end position valuations for the mark-to-market calculation
Clear separation between business trades and investment positions
Documentation supporting your Trader Tax Status qualification
Form 3115 filing confirmation

A trading journal that supports MTM accounting mode automates the year-end mark-to-market calculation and generates the proper tax reports.

Frequently Asked Questions

How do I qualify for Trader Tax Status?

The IRS looks at several factors: frequency of trading (hundreds of trades per year), average holding period (typically days, not weeks), time spent trading (multiple hours daily), intent to profit from short-term movements, and substantial income from trading. There is no bright-line test, so maintaining detailed records of your trading activity is essential.

Can I revoke the MTM election?

Yes, but it requires IRS approval through Form 3115 (Application for Change in Accounting Method). The revocation takes effect the following tax year. This is rarely recommended because losing MTM status means wash sale rules apply again and you lose the unlimited loss deduction.

Does MTM apply to my investment portfolio?

No. You can separate your trading business from your investment portfolio. Securities held for investment (long-term holdings, retirement accounts) are not affected by the MTM election. However, you must clearly identify which positions are business trades versus investment holdings.
