The Double-Tax Problem

Here's what your broker gets wrong — and how we fix it.

❌ What your broker reports

Form 1099-B (Incorrect)

Sale Proceeds$25,000
Cost Basis$21,250
Taxable Gain$3,750

⚠ Basis uses only what you paid — ignores the discount already taxed on your W-2

→
✅ With TaxedTwice correction

Form 8949 (Correct)

Sale Proceeds$25,000
Adjusted Basis$25,000
Actual Gain$0

✓ Basis includes the $3,750 ESPP discount already reported as W-2 income

Without the correction, you're paying tax on $3,750 you already paid through your paycheck. At 30%, that's $1,125 straight back in your pocket. The system just double-taxed you. Nobody will tell you — not your broker, not your accountant. We will. And then we'll fix it.

💡 What this means

Common Questions

What is the ESPP double-tax problem?

When you sell ESPP shares, the discount (typically 15%) is included as ordinary income on your W-2. But your broker reports cost basis on Form 1099-B using only what you paid — the discounted price. Without adjusting your basis, you pay tax on that discount twice: once on your W-2 and again as capital gains.

Where do I find Form 3922?

Your employer provides Form 3922 after you purchase shares through your ESPP. Check your stock plan administrator (Fidelity, E*TRADE, Schwab, Morgan Stanley) under tax documents. It's typically available by January 31 following the purchase year.

Qualifying vs. disqualifying — what's the difference?

A qualifying disposition means you held shares for 2+ years from the grant date AND 1+ year from purchase. A disqualifying disposition is everything else. Either way, you need a basis adjustment to avoid double taxation.

Can I fix prior year returns?

Yes. If you sold ESPP shares in the last 3 years without adjusting your basis, you can file Form 1040-X to claim a refund. We recommend working with a tax professional for amended returns.
