Step 6 — Crypto Asset Cost Basis (QBO-Tracked)
QBO Setup for Crypto:
- - Create a separate Other Current Asset account per crypto type (e.g., "Bitcoin Holdings", "Ethereum Holdings")
- Record purchases as asset debits; sales as credits with gain/loss to Other Income or Other Expense
Cost Basis Methods:
| Method | Description | IRS Compliance |
|---|
| FIFO | First purchased = first sold | Default, IRS-accepted |
| LIFO |
Last purchased = first sold | Accepted but must be consistent |
| HIFO | Highest cost = first sold | Accepted; minimizes gains |
| Specific ID | Choose exact lot | Requires documentation |
Crypto Workpaper Template (per asset):
CODEBLOCK1
QBO Journal Entry for Crypto Sale:
CODEBLOCK2
DeFi / Staking Income:
- - Record staking rewards as Other Income at FMV on date received
- Taxed as ordinary income (not capital gains) at receipt
- Future sale creates capital gain/loss from FMV basis
Step 7 — Reclassification Identification
Run these checks against QBO trial balance before workpaper finalization:
Common Misclassifications:
| Issue | Check | Fix |
|---|
| Capital improvements coded as repairs | Single transaction > $2,500 in Repairs & Maint. | Reclassify to Fixed Assets; depreciate |
| Owner draws in payroll |
Distributions in wage accounts | Move to Owner's Draw / Equity |
| Personal expenses in business | Mixed personal charges | Reclassify to Due from Owner / Shareholder |
| Meals coded as Entertainment | Pre-2018 habit; Entertainment 0% deductible | Separate Meals (50%) from Entertainment (0%) |
| Loan proceeds in Income | Deposit from business loan coded as revenue | Reclassify to Liability account |
| Prepaid expenses expensed | Subscriptions paid for future periods | Pro-rate; book prepaid asset |
| Security deposits as income | Refundable deposits in revenue | Reclassify to Liability |
Threshold Rules:
- - Section 179 / Bonus Depreciation: Fixed assets ≥ $2,500 (safe harbor) → track in 4562
- 1099-NEC Trigger: Any contractor receiving ≥ $600/year → verify W-9 on file
- Meals Documentation: Receipt + business purpose required for deductibility
Step 8 — Trial Balance → Workpaper Output Format
Workpaper Header (required per SSVS standards):
CODEBLOCK3
Standard Workpaper Tabs (Excel):
- 1.
TB — Trial Balance (direct QBO export, unadjusted) - INLINECODE1 — Adjusting Journal Entries (reclassifications, accruals)
- INLINECODE2 — Adjusted Trial Balance (TB + AJE)
- INLINECODE3 or
1120-S — Schedule mapping with line references - INLINECODE5 — 4562 depreciation schedule
- INLINECODE6 — Cost basis tracker (if applicable)
- INLINECODE7 — Contractor payment summary for 1099-NEC filing

Negative Boundaries (When NOT to Use)
- - ❌ Filing tax returns — This skill maps and prepares workpapers; actual filing requires licensed tax software (Drake, UltraTax, ProConnect) and a licensed preparer
- ❌ Legal tax advice — Specific tax strategies, elections, or planning require CPA/EA/attorney opinion
- ❌ Replacing CPA review — Workpapers always require professional review before filing
- ❌ Non-QBO accounting systems — Mappings assume QBO chart of accounts; adapt for Xero, Wave, or FreshBooks
- ❌ International tax (non-US) — IRS schedules only; no VAT, GST, or foreign jurisdiction guidance
- ❌ State tax returns — State conformity varies; this skill covers federal only
- ❌ Real-time QBO API access — This is a workpaper and mapping skill, not a live QBO integration (see qbo-automation skill for API work)
