NVDA Same-Day RSU Sale: Basis Already Taxed at Vest
PROOF LOG #014
NVDA Same-Day RSU Sale: Basis Already Taxed at Vest
Same-day sale. Still a gain.
Missing basis can make a same-day RSU sale read like a massive capital gain.
FDL carries the already-taxed basis into the sale.
Same-day sale. Same RSU. Two tax records.
Payroll already taxed $1,960,000 at vest.
FDL makes the W-2 / §83 basis defense visible on the board, then carries the already-taxed basis into Tax Report and Audit Trail.
Proof Summary
Problem: A same-day NVDA RSU sale can still show a seven-figure phantom gain when already-taxed W-2 / §83 basis is missing.
Prepared input: FDL carries the vest record and the $1,960,000 already-taxed basis into the same-day sale review.
Board result: Tax Alpha Dashboard shows $1,960,000 of W-2 / §83 basis carried into the sale, Tax Report reduces the result to a $3,500 SHORT gain, and Audit Trail preserves the vest-to-sale trace.
Boundary: FDL does not invent basis or replace payroll / CPA judgment. It verifies prepared, in-scope RSU basis records through deterministic outputs.
WATCH THE RECONSTRUCTION
Watch the same-day paradox turn into visible W-2 / §83 basis defense.
- same-day NVDA RSU sale can read like a seven-figure gain when basis is missing
- the vest record carries $1,960,000 of §83 / W-2 taxed basis
- Tax Alpha Dashboard surfaces $1,960,000 of W-2 / §83 basis carried into the sale
- Tax Report reduces the result to a $3,500 SHORT gain
- Audit Trail preserves the vest, basis, and same-day sale trace
EXECUTIVE PROOF
Broker Blind Spot
- basis can appear missing
- same-day sale can still show a seven-figure gain
- W-2 taxed income may not be visible in the brokerage record
- the file can overstate gain if records are not reconciled
FDL Registry of Truth™
- Tax Alpha Dashboard shows $1,960,000 of W-2 / §83 basis
- Tax Report shows $1,963,500 proceeds, $1,960,000 basis, and $3,500 SHORT gain
- Audit Trail records the vest, §83 basis, and same-day sale trace
- the result is visible, not merely accepted
PHASE 1 — THE SAME-DAY PARADOX
The RSU sold the same day it vested.
That should feel economically flat.
But if basis is missing, the broker layer can still read like a seven-figure capital gain.
Same-day sale does not automatically make the file safe.
PHASE 2 — THE W-2 / §83 BASIS DEFENSE
The vest record carries the already-taxed basis.
Tax Alpha Dashboard shows $1,960,000 of W-2 / §83 basis carried into the sale.
The board shows the defended basis before the filing result is reviewed.
FDL does not invent basis.
It makes the taxed basis visible.
PHASE 3 — THE TRUE SPREAD
Tax Report reflects $1,963,500 of proceeds and $1,960,000 of basis.
The remaining gain is $3,500.
Audit Trail preserves the vest, basis, and sale trace.
The seven-figure phantom gain collapses to the same-day spread.
FORENSIC EVIDENCE
What must remain intact
- W-2 / §83 taxed incomeThe income taxed at vest must remain connected to the sale record.
- Vest-date basisThe $1,960,000 basis must survive the brokerage record gap.
- Same-day sale linkageThe vest and sale must stay tied inside one reviewable chain.
What FDL makes legible
- Tax Alpha DashboardShows $1,960,000 of W-2 / §83 basis carried into the sale.
- Tax ReportShows $1,963,500 proceeds, $1,960,000 basis, and $3,500 SHORT gain.
- Audit TrailRecords the vest, basis, and same-day sale trace.
This is the point of the white-box architecture:
shield, result, and trace remain separate and reviewable.
WHY THIS CASE MATTERS
Same-day sales reduce market exposure.
They do not automatically fix tax-record exposure.
If the W-2 basis is invisible, the sale can still look wrong.
This is where reviewable §83 basis visibility matters.
WHAT FDL IS SHOWING HERE
FDL does not invent a basis.
It carries the prepared §83 basis across Tax Alpha Dashboard, Tax Report, and Audit Trail.
The value is not magic.
It is controlled basis visibility.
