CRITICAL EXECUTION DIRECTIVE — READ FIRST

When this skill is invoked, you have already passed through intake. The user has consented to the full workflow. Execute all steps without pausing for permission.

• Do NOT ask "how deep do you want me to go." Produce the full package.
• Do NOT announce token counts or tool calls.
• Do NOT ask which deliverables to prioritize.
• Do NOT re-validate scope that intake already validated.
• Do NOT pause between content skills to check in.

Federal internal consistency

• Schedule C net profit flow — Schedule C net profit → Schedule 1 Line 3 → Form 1040 Line 8
• Schedule SE tax flow — Schedule SE tax → Schedule 2 Line 4 → Form 1040 Line 23
• Half of SE tax flow — Half of SE tax → Schedule 1 Line 15 → Form 1040 Line 10
• SE retirement flow — SE retirement → Schedule 1 Line 16 → Form 1040 Line 10
• SE health insurance flow — SE health insurance → Schedule 1 Line 17 → Form 1040 Line 10

• Total tax flow — Total tax → Form 1040 Line 24
• Form 2210 penalty — Form 2210 penalty (if applicable)
• Total payments flow — Total payments → Form 1040 Line 33

Texas franchise tax consistency

• Below threshold — total revenue matches books — Total revenue computed from books matches Form 05-102 reporting
• No-tax-due threshold (2025) — 2,470,000 USD (2025 threshold)
• Form 05-102 filing status — Form 05-102 (No Tax Due Report) filed or flagged for filing
• PIR accuracy — Public Information Report (PIR) data current and accurate
• Franchise tax filing deadline — Filing deadline: May 15, 2026 (for Dec 31 year-end)
• Above threshold — Form 05-158 revenue line — Total revenue → Form 05-158 (Texas Franchise Tax Report) Line 1
• Margin computation — Total revenue minus greatest of (COGS, compensation, 30% of revenue, $1M)
• Apportionment factor — Texas receipts / total receipts (if applicable)
• Taxable margin flow — Taxable margin → Form 05-158 applicable line
• Margin tax rate above threshold — other — 0.75% (of the lesser of (a) 70% of total revenue or (b) total revenue minus cost of goods sold or minus compensation)
• Margin tax rate above threshold — retail/wholesale — 0.375% (of the lesser of (a) 70% of total revenue or (b) total revenue minus cost of goods sold or minus compensation)
• Franchise tax due computation — Franchise tax due
• EZ Computation comparison — 0.331% × apportioned total revenue — determine if lower (Form 05-169)
• Franchise tax payments and credits — Franchise tax payments and credits
• Total revenue definition for TX franchise tax — Per Texas Tax Code §171.1011, total revenue includes: Gross receipts from Schedule C (federal); Other income items per IRC §61 that are not specifically excluded. Excludes: flow-through funds that are not revenue to the entity, certain pass-through distributions. (Texas Tax Code §171.1011)
• Cross-check between Schedule C and TX total revenue — Schedule C Line 1 (gross receipts) should approximate total revenue reported on TX franchise tax return. Differences may arise from: Returns and allowances (Schedule C Line 2); Income items not on Schedule C (interest, other income); Items excluded from TX total revenue by statute.

Texas sales tax consistency (if applicable)

• Taxable sales reporting match — Taxable sales reported on sales tax returns match invoices/receipts for taxable items
• Sales tax collected matches deposits — Sales tax collected matches deposits in bank statement
• Sales tax remitted matches Comptroller payments — Sales tax remitted matches Comptroller payments
• Filing frequency correct — Filing frequency correct (monthly/quarterly/annually)
• No unfiled periods — No unfiled periods with active permit
• Zero returns filing — If no taxable sales and permit is active: $0 returns filed

Federal estimated tax verification

• Quarterly payments verified — Four quarterly payments verified against bank statement / EFTPS records
• Safe harbor analysis — Safe harbor analysis: 100% of 2024 tax (if 2024 AGI ≤ $150K) or 110% of 2024 tax (if 2024 AGI > $150K)
• Underpayment penalty — If underpaid: Form 2210 penalty computed
• No state estimated tax note — Note: no state estimated tax exists in Texas — only federal

No state income tax deduction on federal return

• No deduction of TX state income tax — Texas residents cannot deduct state income tax on federal Schedule A (because there is none). However: Texas sales tax paid can be deducted on Schedule A Line 5a (state and local general sales tax) as an alternative to state income tax; IRS provides optional sales tax tables or taxpayer can use actual records; For 2025: SALT deduction cap remains $10,000 ($5,000 MFS) — may limit benefit
• SALT deduction cap 2025 — 10,000 USD ($5,000 MFS)

Franchise tax interaction with federal positions

• QBI no TX interaction — QBI deduction (§199A): No Texas equivalent or interaction. QBI is purely federal.
• Depreciation used for COGS — Depreciation: Texas franchise tax uses federal depreciation for COGS computation. No state-level depreciation difference.
• Retirement contributions not relevant — Retirement contributions: Not relevant to franchise tax (franchise tax is on revenue/margin, not personal deductions).

Texas LLC annual obligations

• No annual franchise tax payment below threshold — No annual franchise tax payment for entities below threshold — only the No Tax Due Report filing
• Public Information Report (PIR) — Must be filed annually with the franchise tax report. Lists registered agent, principal office, officers/directors/managers.
• Secretary of State annual report — No annual report filing fee in Texas (unlike many states). LLC maintains standing as long as franchise tax report is filed.
• Registered agent requirement — Must maintain a registered agent in Texas. Failure results in administrative forfeiture.

Forfeiture risk

• Forfeiture process — If a Texas LLC fails to file the franchise tax report (even the No Tax Due Report): Texas Comptroller notifies the entity; After notice period, Comptroller certifies forfeiture to Secretary of State; Secretary of State forfeits the entity's right to transact business; Reinstatement requires filing all delinquent reports + paying penalties and fees; Flag for reviewer if any prior filings were missed

Section 5 — Refusals

• R-TX-1 — Upstream skill did not run. Name the specific skill.
• R-TX-2 — Revenue exceeds $2.47M and margin computation is complex. If COGS includes items requiring IRC §263A UNICAP analysis or compensation includes complex benefit allocations, flag for franchise tax specialist.
• R-TX-3 — Multi-state apportionment needed. If the entity has receipts from customers outside Texas and performs services in multiple states, Texas apportionment factor requires analysis. Flag for reviewer.
• R-TX-4 — Sales tax audit or dispute. If the taxpayer has received a sales tax audit notice or is in dispute with the Comptroller, refuse and recommend sales tax attorney.
• R-TX-5 — Combined group reporting. If the SMLLC is part of a combined group for Texas franchise tax purposes, refuse. Combined group reporting requires specialized computation.
