What variance thresholds are acceptable?

Set numeric thresholds (e.g., USD 100 gross, USD 25 tax) and apply consistently. Material breaks require root cause and closure evidence.

Do we reconcile counts as well as amounts?

Yes — record counts by income code and pool often surface mapping or pooling issues even when totals look close.

How do we evidence corrections?

Keep FIRE receipts/submission IDs, error reports, and a corrections log with Before/After and closure notes. Link them in the Evidence Index.

QI Reconciliation Methods and Templates Explained

QI reconciliations — 1042-S ↔ 1042 ↔ GL (method & templates)

A clean QI reconciliation proves that 1042-S totals roll to Form 1042 and Form 1042 ties to the GL. Use this method, variance thresholds, and the templates below to generate reviewer-ready evidence.

Scope: 1042-S creation (pools/rates), roll-up to Form 1042 schedules, and tie-out to GL. Includes corrections handling and receipt evidence (FIRE).

1) The three-bridge method

1042-S → 1042 (Schedule map): roll up by income code, chapter, rate/pool to the appropriate 1042 lines.
Adjustments: post close corrections, timing, immaterial rounding — document explicitly.
1042 → GL: tie tax payables/expense to GL balances (period/YTD); note FX policy.

2) Variance thresholds & sign-offs

Gross variance: set a numeric threshold (e.g., USD 100) per income code/line.
Tax variance: tighter threshold (e.g., USD 25) due to rounding and small timing items.
Counts: track 1042-S record counts vs schedule lines to spot pooling/mapping issues.
Sign-offs: maker checks, Tax Lead approves; store dated approvals with the pack.

3) Common breaks (and quick fixes)

Break	Why it happens	Fix
Pool mismatch (rate vs box)	Mapping not aligned to 1042-S schema	Re-map pools; run validation on pool→box mapping
Income code drift	Product mis-classification	Lock a product→income code table; unit tests
Rounding/FX noise	Inconsistent rate/date	Fix FX policy; standardize rounding (2dp)
GL balance off vs 1042	Manual postings; timing differences	Reconcile postings; document timing adj.

4) Evidence pack — what to keep

Final 1042-S export (hash/checksum if available) + FIRE receipts/corrections.
Form 1042 (signed) and schedules; reconciliation workbook with thresholds.
GL TB and journal entries; period & YTD tie-outs, FX policy disclosure.
Approvals & sign-offs (maker/checker) stored next to the pack.
