missed 475(f) deadline as a day trader — am I locked into capital loss limit?

started day trading full-time jan 2025. did about 3,400 round trips that year. ended 2025 down $61k after a brutal Q3. just realized i needed to elect 475(f) mark-to-market BY APRIL 15 OF THE PRIOR YEAR to deduct the full loss as ordinary income. so for 2025 losses i needed to elect by 4/15/24, and for 2026 i needed to elect by 4/15/25.

i didn't. so i'm stuck with $3k/year capital loss limit on the $61k? feels like that can't be right.

unfortunately yes — the 475(f) election is "irrevocable" and timing is strict. for 2025 losses you're stuck with the $3k offset and carryforward. for 2026 onwards, you needed to elect by 4/15/25, which has passed.

BUT — for 2027 you can still elect by 4/15/26. so do that NOW for 2027. the silver lining of the carryforward is that future cap gains let you absorb the loss faster than ordinary income would.

also: were you a "trader in securities" by IRS standards? that's a separate determination from 475(f) — even without the election you may have ordinary deductions on business expenses if you qualify as a trader (Schedule C).

also look into rev proc 99-17 late election relief — there's a narrow window where IRS will grant late 475(f) for "reasonable cause." rare but worth a phone call to a CPA who specializes in trader tax.

I'm Sergei Tokmakov, California attorney (Bar #279869). The CPA advice above is correct. Two structural points:

(1) Trader Tax Status (TTS) is the threshold determination — you need substantial, frequent, regular trading activity with the goal of profiting from short-term price movements. 3,400 round trips in a year almost certainly qualifies. TTS alone gets you Schedule C deductions for business expenses (home office, market data, software, education) without the 475(f) election. That's not nothing — typical TTS deductions are $8-15k/yr.

(2) For the 2025 loss, the $3k/yr cap applies but capital loss carryforward is unlimited in years. If you have offsetting gains in 2026-2030 you'll absorb the carryforward faster. Combined with TTS deductions and a 2027 475(f) election filed by 4/15/26, you can substantially mitigate going forward. Talk to a trader-specialist CPA — informational only.
