You sold RSU shares and tax software shows a huge capital gain even though you already paid tax when the shares vested. You need to see how W-2 wages and a 1099-B sale both appear without taxing the same dollars twice — and which form lines to fix.

In plain terms

Usually no, not on the same dollars. Tax at is wage income on the value when shares . When you sell, you are taxed on the change in price after that, not on the full sale amount again. It can look like double tax because both events show up on different forms — especially when reports $0 basis.

Gather before you start

  • for the year the shares vested.
  • for the sale (proceeds and reported basis).
  • confirmation with per share on the .
  • Rough idea of sale price and date.

How the tax works

At , payroll reports the full market value as wages on your Box 1 — that is the first tax event. for the shares you keep is usually the same , so the IRS expects sale gain on Form 8949 to exclude those dollars already taxed as wages. The and the later brokerage sale are two different events on two different forms, not a duplicate wage entry.

Brokers often leave basis blank or show $0 on Box 1e because payroll, not the brokerage, recorded the income. Tax software imports that without knowing your history unless you override basis manually. Accepting $0 basis overstates and creates the feeling of double taxation even though the fix is a basis adjustment, not deleting the .

Correct reporting puts into Form 8949 as for the shares sold, so taxable gain (or loss) equals sale proceeds minus , adjusted for fees. If you sold at a loss below , you still report the sale; the capital loss does not undo the wage tax that already hit at . at is a separate tiny sale with its own line and nearly zero holding period.

Multiple lots sold in one broker line need lot-level basis from each confirmation. Mixing and sales on the same account can confuse software defaults. Keep confirmations next to the so you can prove Box 1e should match wages already reported for those shares.

When basis is set correctly, you never re-enter wages on the return for the sale year. The belongs on the for the year; the sale belongs on Form 8949 and Schedule D. That split is why both forms appear without meaning the same dollars were taxed twice.

What to check on your end

  • Whether wages appear in Box 1 for the year.
  • proceeds vs reported basis (often $0).
  • per share × shares sold = proposed basis.
  • Gain after basis adjustment vs price change since .
  • Whether tax software imported the without an adjustment.

Accepting $0 basis because the form says so

That overstates and feels like double taxation. The fix is usually a basis adjustment tied to income on your , not deleting the or re-entering the as income a second time.

What to pull from your files

  • Box 1 and any /stock plan line items for the year.
  • Box 1d proceeds and Box 1e .
  • confirmation: date, shares, used by payroll.
  • Broker supplemental lot report if available.
  • Trade confirmation showing sale price and fees.

Example scenario (hypothetical)

Illustration only, not your tax situation.

Jordan vests 200 shares at $40 ($8,000 on the ). Jordan sells all 200 later at $42. Correct economics: $8,000 was taxed as wages; the sale adds about $400 of . If the shows $8,400 proceeds and $0 basis, tax software might compute an $8,400 gain unless Jordan adjusts basis to $8,000 on Form 8949.
