Vendor Compliance 1099

1099 vendor compliance pipeline for accounting firms. Pulls full-year General Ledger from QBO, aggregates vendor payments, applies IRS $600 threshold, classifies 1099-NEC vs 1099-MISC, checks corporate exemptions, tracks W-9 and TIN status, filters credit card payments (1099-K handled by processor), calculates late-filing penalties, and produces year-over-year CDC. Outputs an 8-tab Excel workbook. Use for year-end 1099 compliance runs, W-9 tracking, and IRS threshold checks. NOT for payroll W-2, 1042-S foreign withholding, or 1099-K reconciliation.

Key IRS Rules Implemented

$600 Threshold

• Applied to ACH/check/wire amounts only — credit card payments excluded (processor files 1099-K)
• Threshold is per-vendor, full calendar year aggregate

1099 Type Classification

Form	When	Keyword triggers
1099-NEC	Non-employee compensation: contractors, consultants, attorneys, sole proprietors	contractor, freelance, consultant, attorney, repair, cleaning, design, etc.
1099-MISC	Rent, royalties, prizes, medical payments	rent, royalty, prize, award, medical, healthcare

Default is 1099-NEC — NEC is assumed for all service payments unless account/memo indicates MISC category.

Corporate Exemption

• Vendor names matching LLC|Inc|Corp|Ltd|Co.|Company|etc. → flagged as potentially exempt
• Still appear in Exemptions tab for manual verification
• Exception — always file regardless of entity type:
  • Attorneys (IRC §6045(f)) → 1099-NEC
  • Medical providers → 1099-MISC Box 6

Payment Method Filter

• Credit card keywords in memo/txn_type/split → classified as CC, excluded from reportable amount
• ACH/check/wire → included in reportable amount
• Unclassified payments → included (conservative — better to over-report)

W-9 & TIN Tracking

• W-9 status persisted at .cache/vendor-compliance-1099/{slug}-w9.json
• New vendors auto-default to NO status
• TIN status persisted at .cache/vendor-compliance-1099/{slug}-tin.json
• Backup withholding: 24% applies if vendor fails to provide valid TIN

Filing Deadlines

Form	Recipient Copy	IRS Paper	IRS e-File
1099-NEC	January 31	January 31	January 31
1099-MISC (Box 7)	January 31	January 31	January 31
1099-MISC (other boxes)	January 31	February 28	March 31

e-File required if filing 10+ information returns.

Penalty Rates (IRC §6721/6722 — 2024)

Days Late	Per Form	Small Biz Annual Cap
≤30 days	$60	$232,500
31–60 days	$120	$664,500
>60 days	$310	$1,329,000
Intentional disregard	$630 minimum	No cap

Small business = avg annual gross receipts ≤$5M for 3 prior years.

Cache Files

File	Purpose
.cache/vendor-compliance-1099/{slug}-{year}.json	YoY snapshot for CDC (auto-saved each run)
.cache/vendor-compliance-1099/{slug}-{year-1}.json	Prior year snapshot for comparison
.cache/vendor-compliance-1099/{slug}-w9.json	W-9 status (persisted, editable manually)
.cache/vendor-compliance-1099/{slug}-tin.json	TIN status (persisted, editable manually)

Updating W-9 status manually:

bash

# Edit cache file directly to update W-9 status
cat .cache/vendor-compliance-1099/my-client-w9.json
# Modify "VendorName": "YES" | "NO" | "PENDING"
# Then re-run pipeline — status will be loaded automatically

---

Integration Requirements

• QBO Client: Node.js QBO client (auth token must be set)
• Python packages: pip install openpyxl
• GL access required: Pipeline reads full-year GL — ensure QBO auth has GL report access
• No write access to QBO — read-only integration

---

Decimal Math

All financial calculations use Python Decimal with ROUND_HALF_UP at 2 decimal places. No float arithmetic. Same pattern as tax-package-prep.py and pl-deep-analysis.py.

---

When NOT to Use This Skill

• Payroll / W-2 compliance → separate payroll workflow
• 1099-K reconciliation → CC processor provides (not Sam's responsibility)
• Foreign vendor withholding → Form 1042-S, different rules
• State-level 1099 filing → varies by state, not covered here
• 1099-INT / 1099-DIV / 1099-B → investment/bank-issued, not vendor compliance

---

Workflow Checklist

Run this pipeline as part of year-end close:

1. November/December: Pre-screen — run pipeline to identify missing W-9s before year-end
2. January (early): Final run — full year GL aggregation
3. January 15: W-9 collection deadline (internal)
4. January 25: Prepare and review filings
5. January 31: File 1099-NEC (recipient + IRS)
6. February 28 / March 31: File 1099-MISC (IRS paper/e-file)
