SPY ACATS Non-Covered Missing Basis: Tax Lot Lineage Defense

PROOF LOG #031

SPY ACATS Non-Covered Missing Basis: Tax Lot Lineage Defense

ACATS moved the position. The receiving surface did not carry the basis. FDL verified the prepared source-lot path.

Receiving Surface
ACATS Can Hide Missing Basis

The shares arrived, but the receiving-custodian surface showed non-covered / basis not reported.

FDL View
FDL Verifies Source-Lot Basis

FDL ties the Schwab sale back to the CPA-prepared Morgan Stanley source lot.

ACATS can move the position.

The receiving-custodian surface may not carry the basis.

In this SPY case, the CPA-prepared source record existed before the transfer: a May 2023 SPY source lot with $4,130,100 of basis.

FDL did not discover missing basis or repair the broker record. It verified the prepared source-lot path after the ACATS transfer.

Non-covered surface ≠ lost basis path.

Proof Summary

Problem: After ACATS, the receiving-custodian surface showed non-covered / basis not reported for the SPY position.

Prepared input: The CPA-prepared Morgan Stanley source lot, ACATS OUT / IN path, and later Schwab sale were entered into FDL as a reviewable transfer record.

Board result: Tax Report shows the Schwab sale with $4,130,100 of basis and a LONG result; Audit Trail preserves the original acquisition date and carryover unit basis.

Boundary: FDL does not infer missing basis or replace CPA judgment. It verifies prepared, in-scope source-lot records after the transfer exists.

WATCH THE BASIS PATH

Watch a non-covered ACATS surface become a reviewable source-lot lineage.

TL;DR
  • ACATS moved 10,000 SPY shares from Morgan Stanley to Schwab
  • The receiving-custodian surface was non-covered / basis not reported
  • FDL verified the CPA-prepared May 2023 source lot
  • Tax Report shows $4,130,100 basis and $1,763,800 LONG gain
  • Audit Trail preserves the source-lot lineage after transfer
  • Tax Alpha Dashboard makes the carryover basis visible

EXECUTIVE PROOF

Receiving / Review Risk

  • the account can move without a reviewable basis surface
  • the receiving custodian may show non-covered / basis not reported
  • the sale may need CPA-prepared source records
  • the reviewer must preserve original acquisition date and basis
  • the filing-facing result must not be inferred from the receiving surface alone

FDL Registry of Truth

  • prepared Morgan Stanley source lot remains the basis source
  • ACATS OUT / IN stays a non-taxable transfer path
  • Schwab sale is tied to the received carryover lot
  • Tax Report uses the prepared carryover basis
  • Audit Trail preserves the source-lot path after transfer

PHASE 1 — THE NON-COVERED SURFACE

10,000 SPY shares moved from Morgan Stanley to Schwab through ACATS.

The receiving-custodian surface showed non-covered / basis not reported.

The shares arrived. The basis path still needed review.

PHASE 2 — THE PREPARED SOURCE RECORD

The CPA-prepared May 2023 SPY source lot existed before the transfer.

FDL carried through $4,130,100 of prepared source basis and the original lot history.

FDL verified prepared source records instead of inferring missing basis.

PHASE 3 — THE FILING-FACING RESULT

Schwab later sold 10,000 SPY shares.

Tax Report shows $5,893,900 proceeds, $4,130,100 basis, and $1,763,800 LONG gain.

Non-covered surface did not become a lost basis path.

PHASE 4 — THE REVIEWABLE LINEAGE

Audit Trail connects the Schwab sale back to the prepared Morgan Stanley source lot.

Tax Alpha Dashboard makes the carryover basis visible.

The account moved. The source-lot path stayed reviewable.

WHAT STAYED REVIEWABLE

Tax Report

The Schwab sale used the prepared carryover basis: $4,130,100 basis, $1,763,800 LONG gain.

The filing-facing result did not rely on the non-covered surface alone.

Audit Trail

The sale stayed tied to the Morgan Stanley source lot through the ACATS OUT / IN path.

The account moved. The source-lot path stayed reviewable.

WHY THIS CASE MATTERS

UHNW clients move large taxable positions across custodians.

After ACATS, the sale surface may be non-covered or basis not reported.

The value is a reviewable source-lot path for a prepared reporting position.

WHAT FDL IS SHOWING HERE

FDL does not discover missing basis or repair broker records.

FDL verifies the prepared source-lot path after the transfer exists.

Non-covered surface ≠ lost basis path.
