SPY Covered vs Noncovered Basis | One Sale, Two Tax Worlds
PROOF LOG #016
SPY Covered vs Noncovered Basis | One Sale, Two Tax Worlds
One SPY sale. Two reporting worlds.
A single sell order can mask different basis burdens inside the same ticker.
FDL separates the legacy burden from the modern covered lot.
One SPY sale. Two reporting worlds.
A legacy 2010 lot carries CPA-prepared noncovered basis.
A 2025 lot carries covered-era basis.
FDL splits the sale and preserves the lot path.
WATCH THE RECONSTRUCTION
Watch one SPY sale become two reviewable tax rows.
- one 6,000-share SPY sale produces two tax rows
- 2010 legacy lot: 5,000 sh, CPA-prepared noncovered basis, LONG
- 2025 covered lot: 1,000 sh consumed, SHORT
- Tax Report shows the long / short split
- Audit Trail preserves which lot left and which shares remain
EXECUTIVE PROOF
Broker Blind Spot
- one sale can mask multiple basis regimes
- legacy noncovered basis becomes the CPA’s burden
- covered-era basis and noncovered basis can blend visually
- the file needs lot-level proof, not a blended sale summary
FDL Registry of Truth™
- Tax Report splits one sale into a 5,000-share LONG row and a 1,000-share SHORT row
- Audit Trail closes the 2010 lot and leaves 2,000 shares open in the 2025 lot
- Transactions preserve the CPA-prepared legacy basis before audit
- the sale becomes reviewable, not blended
PHASE 1 — THE MIXED SALE
One SPY sell order disposes of 6,000 shares.
Inside that sale, two different basis worlds are present.
The 2010 legacy lot carries CPA-prepared noncovered basis.
The 2025 lot carries covered-era basis.
Same ticker does not mean one basis burden.
PHASE 2 — THE LONG / SHORT SPLIT
FDL separates the single SPY sale into two Tax Report rows.
The 2010 lot becomes a 5,000-share LONG result.
The 2025 lot contributes 1,000 shares to a SHORT result.
One sale becomes two filing-facing tax rows.
PHASE 3 — THE REVIEWABLE LOT PATH
Audit Trail shows the 2010 lot fully consumed and closed.
It also shows the 2025 lot partially consumed, with 2,000 shares still open.
The tax result stays connected to the source lots.
FDL keeps the basis burden reviewable.
FORENSIC EVIDENCE
What must remain intact
- 2010 legacy basisThe $566,650 noncovered basis must remain tied to the 2010 source lot.
- 2025 covered-era basisThe $666.82 unit basis must remain tied to the modern covered lot.
- FIFO consumption pathThe oldest lot must close before the next lot is partially consumed.
- Remaining inventoryThe 2025 lot must retain the 2,000 shares that did not leave.
What FDL makes legible
- Tax ReportShows 5,000 sh LONG from the 2010 lot and 1,000 sh SHORT from the 2025 lot.
- Audit TrailShows the 2010 lot closed and the 2025 lot still open with 2,000 shares remaining.
- TransactionsCaptures the CPA-prepared legacy basis before the sale is evaluated.
This is the point of the white-box architecture:
tax rows, source lots, and remaining inventory stay separate and reviewable.
WHY THIS CASE MATTERS
Covered and noncovered lots can sit inside the same ticker.
When one sale crosses both, the filing burden changes by lot.
For UHNW accounts with legacy ETF positions, that distinction is not academic.
It is the difference between a blended sale and a reviewable tax file.
WHAT FDL IS SHOWING HERE
FDL is not creating alpha.
FDL is proving ledger integrity.
Same ticker. Same sale. Different basis burden.
Still reviewable.
