| 2 | name: es-return-assembly |
| 3 | description: Final orchestrator skill that assembles the complete Spain filing package for Spain-resident self-employed individuals (autónomos). Consumes outputs from all Spain content skills (spain-vat-return for Modelo 303, es-income-tax for IRPF Modelo 100, es-social-contributions for RETA, es-estimated-tax for Modelo 130 pagos fraccionados) to produce a single unified reviewer package containing every worksheet, every form, every brief section, all cross-skill reconciliations, and the final action list with payment instructions, filing instructions, and next-year planning. This is the capstone skill that runs last and produces the final deliverable. MUST be loaded alongside all Spain content skills listed above. Spain full-year residents only. Autónomos (self-employed individuals) only. |

| 8 | |
| 9 | ## CRITICAL EXECUTION DIRECTIVE -- READ FIRST |
| 10 | |
| 11 | **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.** |
| 12 | |
| 13 | Specifically: |
| 14 | |
| 15 | - **Do NOT ask the user "how deep do you want me to go"** or "do you want the full package" or any variant. The user asked for their tax returns. They want their tax returns. Produce them. |
| 16 | - **Do NOT announce how many tokens or tool calls this will take.** Execute. |
| 17 | - **Do NOT ask which deliverables to prioritise.** Produce all deliverables listed in Section 4. If you run out of context mid-execution, finish the computation work first (numbers, positions, flags) then produce whatever formatted outputs you can, and at the very end state clearly which deliverables were not produced and why. |
| 18 | - **Do NOT re-validate scope that intake already validated.** If `es-freelance-intake` produced an intake package, trust it. You can cross-check specific numbers during reconciliation but do not re-interrogate the user about residency, business structure, or anything else intake already captured. |
| 19 | - **Do NOT pause between content skills to check in.** Run them in dependency order (Section 2) without prose status updates between each one. A single status message at the end is fine. |
| 20 | - **Self-checks are targets, not blockers.** If a self-check fails, note it in the reviewer brief's open flags section and continue. Do NOT halt the entire workflow because one self-check had an ambiguous answer. |
| 21 | - **Primary source citations go in the final reviewer brief, not in intermediate computation steps.** |
| 22 | |
| 23 | **The user has already been told (by the intake skill) that the final package requires asesor fiscal signoff before filing. State it once in the final output and move on.** |
| 24 | |
| 25 | **Failure mode to avoid:** The skill halts mid-execution and asks the user a meta-question about workflow pacing. If you feel the urge to ask "how should I proceed," the correct action is to pick the most defensible path and proceed, flagging the decision in the reviewer brief so the reviewer can challenge it. |
| 26 | |

| 28 | |
| 29 | ## What this file is |
| 30 | |
| 31 | The final capstone skill for Spain self-employed returns. Every Spain content skill feeds into this one. The output is the complete reviewer package that an asesor fiscal can review, sign off on, and deliver to the client along with filing instructions. |
| 32 | |
| 33 | This skill coordinates execution of the content skills, verifies cross-skill consistency, and assembles the final deliverable. |
| 34 | |
| 35 | --- |
| 36 | |
| 37 | ## Section 1 -- Scope |
| 38 | |
| 39 | Produces the complete Spain filing package for: |
| 40 | - Full-year Spanish residents (territorio común -- excludes País Vasco and Navarra foral regimes) |
| 41 | - Autónomos (self-employed individuals, personas físicas) |
| 42 | - Tax year 2025 |
| 43 | - Filing Modelo 303 (IVA trimestral), IRPF Modelo 100, RETA reconciliation, Modelo 130 (pagos fraccionados) |
| 44 | |
| 45 | --- |
| 46 | |
| 47 | ## Section 2 -- Execution order and dependency chain |
| 48 | |
| 49 | The skill enforces the following execution order: |
| 50 | |
| 51 | 1. **`spain-vat-return`** -- Modelo 303 IVA return (Q2 skill) |
| 52 | - Runs first because IVA base imponible feeds into the IRPF |
| 53 | - For Q4 2025: prepare Modelo 303 if not yet filed; verify Q1-Q3 figures |
| 54 | - Reconcile facturas emitidas (output IVA) with facturas recibidas (input IVA) |
| 55 | - Handle intracomunitarias (reverse charge, Modelo 349) |
| 56 | - Output: Modelo 303 box values, IVA devengado, IVA soportado deducible, result (a ingresar / a compensar / a devolver) |
| 57 | |
| 58 | 2. **`es-income-tax`** -- IRPF Modelo 100 annual return (Q2 skill) |
| 59 | - Depends on IVA output: rendimiento íntegro de actividades económicas must use base imponible (ex-IVA) from Modelo 303 |
| 60 | - Compute rendimiento neto: ingresos - gastos deducibles - amortización - RETA cuotas |
| 61 | - Apply gastos de difícil justificación (5%, max EUR 2,000) for simplificada |
| 62 | - Apply reducciones (if applicable) |
| 63 | - Compute base imponible general + base del ahorro |
| 64 | - Apply escala estatal + autonómica |
| 65 | - Deduct retenciones, pagos fraccionados (Modelo 130) |
| 66 | - Output: Modelo 100 key boxes, cuota líquida, resultado de la declaración |
| 67 | |
| 68 | 3. **`es-social-contributions`** -- RETA cotizaciones sociales (Q2 skill) |
| 69 | - Depends on IRPF: RETA cuotas are a gasto deducible in the rendimiento neto computation |
| 70 | - Reconcile actual cuotas paid vs the new income-based contribution system (since 2023) |
| 71 | - Verify base de cotización is appropriate for income level |
| 72 | - Flag if regularisation is expected (TGSS adjusts RETA based on actual income, with potential refund or additional payment) |
| 73 | - Output: annual RETA paid, base de cotización, regularisation estimate, deductibility confirmation |
| 74 | |
| 75 | 4. **`es-estimated-tax`** -- Modelo 130 pagos fraccionados (Q4 stub, compute 20% quarterly) |
| 76 | - Depends on IRPF: pagos fraccionados are computed as 20% of rendimiento neto acumulado minus retenciones acumuladas |
| 77 | - **Status check:** es-estimated-tax is currently a Q4 stub. If the stub has substantive computation content, use it. If it is still a placeholder, compute Modelo 130 using the standard formula (Art. 110 LIRPF: 20% x rendimiento neto acumulado - retenciones - pagos fraccionados anteriores) and flag in the reviewer brief that the dedicated skill was not available. |
| 78 | - Output: Q4 2025 Modelo 130 computation, and 2026 quarterly schedule |
| 79 | |
| 80 | If any upstream content skill fails to produce validated output, the assembly skill notes the failure in the reviewer brief and continues with available data rather than halting entirely. |
| 81 | |

| 83 | |
| 84 | ## Section 3 -- Cross-skill reconciliation |
| 85 | |
| 86 | ### Cross-check 1: Modelo 303 base imponible = IRPF ingresos de actividades económicas |
| 87 | |
| 88 | | IVA Output | IRPF Input | Rule | |
| 89 | |-----------|-----------|------| |
| 90 | | Modelo 303 total base imponible (annual) | Modelo 100 rendimiento íntegro actividades económicas | Must match within EUR 1 | |
| 91 | | Domestic supplies base imponible | IRPF ingresos with IVA repercutido | Ex-IVA amount | |
| 92 | | Intracomunitarias (reverse charge) | IRPF ingresos | Included in income, IVA neutral | |
| 93 | | Exportaciones (non-EU) | IRPF ingresos | Included in income, IVA exempt with right to deduction | |
| 94 | |
| 95 | **If mismatch:** Flag for reviewer. Common causes: timing differences (devengo vs cobro if using criterio de caja), autoconsumo, corrective invoices (facturas rectificativas). |
| 96 | |
| 97 | ### Cross-check 2: RETA cuotas = gasto deducible in IRPF |
| 98 | |
| 99 | | RETA Output | IRPF Input | Rule | |
| 100 | |------------|-----------|------| |
| 101 | | Total RETA cuotas paid in 2025 | Gastos de Seguridad Social in Modelo 100 | Must match exactly | |
| 102 | | Tarifa plana months (if applicable) | Lower cuota for those months | Correctly reflected | |
| 103 | | Regularisation payment/refund | Included in year paid / received | Adjusts deductible amount | |
| 104 | |
| 105 | **If mismatch:** Verify months of alta. Part-year alta means prorated cuotas. If regularisation happened in 2025 for prior year, it is deductible in 2025. |
| 106 | |
| 107 | ### Cross-check 3: Retenciones credit against final IRPF cuota |
| 108 | |
| 109 | | Source | Amount | Treatment | |
| 110 | |--------|--------|-----------| |
| 111 | | Retenciones soportadas on facturas emitidas | Sum from facturas / Modelo 190 data | Credit against cuota íntegra in Modelo 100 | |
| 112 | | Retenciones from employment (if any) | From nómina / Modelo 190 | Credit against cuota íntegra | |
| 113 | | Retenciones from capital income (if any) | From bank certificates | Credit against cuota íntegra | |
| 114 | |
| 115 | **Rule:** Total retenciones deducted in Modelo 100 must equal the sum of all retenciones from all sources. If retenciones exceed cuota íntegra, the result is a devolver (refund). |
| 116 | |
| 117 | **If mismatch:** Common cause is retención not actually withheld (client paid gross despite invoice showing retención). Flag for reviewer: income still declared at gross, but retención credit requires actual withholding. |
| 118 | |
| 119 | ### Cross-check 4: Modelo 130 pagos fraccionados credit against final IRPF |
| 120 | |
| 121 | | Source | Amount | Treatment | |
| 122 | |--------|--------|-----------| |
| 123 | | Modelo 130 Q1-Q4 payments | Sum of four quarterly payments | Credit against cuota líquida in Modelo 100 | |
| 124 | | Formula: 20% x rendimiento neto acumulado - retenciones acumuladas - pagos anteriores | Per quarter | Standard computation | |
| 125 | |
| 126 | **Rule:** If retenciones on professional invoices cover > 70% of income, Modelo 130 filing is not required (Art. 110.3.c RIRPF). Check this condition. |
| 127 | |
| 128 | **If mismatch between computed Modelo 130 and amounts actually paid:** Flag for reviewer. If underpaid, no separate penalty (it washes into the annual IRPF), but cash flow impact. If overpaid, credit against IRPF. |
| 129 | |

| 307 | |
| 308 | ## Section 6 -- Self-checks |
| 309 | |
| 310 | **Check ES-A1 -- All upstream skills executed.** spain-vat-return, es-income-tax, es-social-contributions all produced output. es-estimated-tax produced output or was computed from standard formula. |
| 311 | |
| 312 | **Check ES-A2 -- Modelo 303 base imponible matches IRPF ingresos.** Within EUR 1 tolerance. |
| 313 | |
| 314 | **Check ES-A3 -- RETA cuotas deducted in IRPF match actual payments.** Exact match. |
| 315 | |
| 316 | **Check ES-A4 -- Retenciones in IRPF match sum of all retenciones from sources.** Retenciones from professional activity + employment + capital = total deducted. |
| 317 | |
| 318 | **Check ES-A5 -- Pagos fraccionados (Modelo 130) correctly credited in IRPF.** Sum of Q1-Q4 payments deducted against cuota líquida. |
| 319 | |
| 320 | **Check ES-A6 -- Gastos de difícil justificación correctly applied (simplificada only).** 5% of rendimiento neto previo (before this deduction), max EUR 2,000. |
| 321 | |
| 322 | **Check ES-A7 -- Escala estatal + autonómica correctly applied.** Correct comunidad autónoma rates used for the autonómica tramo. |
| 323 | |
| 324 | **Check ES-A8 -- Vehicle IVA deduction at appropriate rate.** Default 50% unless exclusive business use demonstrated. |
| 325 | |
| 326 | **Check ES-A9 -- Home office (if claimed) correctly computed.** Proportional m2 applied to eligible costs; suministros at 30% of proportional share (simplificada rule from 2018). |
| 327 | |
| 328 | **Check ES-A10 -- Retención rate correct.** 7% for first 3 calendar years from alta; 15% thereafter. Check alta date. |
| 329 | |
| 330 | **Check ES-A11 -- Filing calendar is complete.** All deadlines for Modelo 303, 130, 100, 349, 390, and 347 are listed with specific dates. |
| 331 | |
| 332 | **Check ES-A12 -- Reviewer brief contains legislation citations.** Every position taken references the specific article of LIRPF, RIRPF, LIVA, RIVA, or relevant regulation. |
| 333 | |
| 334 | --- |
| 335 | |
| 336 | ## Section 7 -- Output files |
| 337 | |
| 338 | The final output is **three files**: |
| 339 | |
| 340 | 1. **`[client_slug]_2025_spain_master.xlsx`** -- Single master workbook containing every worksheet and computation. Sheets include: Cover, Modelo 303 (Q4 or annual reconciliation), IRPF Modelo 100 (rendimiento neto, base imponible, escala, cuota, resultado), Amortisation Schedule, Gastos Detail, RETA Reconciliation, Modelo 130 (Q4 2025 + 2026 schedule), Cross-Check Summary. Use live formulas where possible -- e.g., IRPF ingresos cell references the Modelo 303 base imponible cell; RETA gasto references the RETA sheet total; Modelo 130 references IRPF rendimiento neto.

| 343 | |
| 344 | 3. **`client_action_list.md`** -- Single markdown file with step-by-step actions: immediate filings and payments, quarterly calendar for 2026, ongoing compliance reminders. |

| 352 | ## Section 8 -- Cross-skill references |
| 353 | |
| 354 | **Inputs:** |
| 355 | - `es-freelance-intake` -- structured intake package (JSON) |
| 356 | - `spain-vat-return` -- Modelo 303 box values and classification output |
| 357 | - `es-income-tax` -- IRPF Modelo 100 computation output |
| 358 | - `es-social-contributions` -- RETA reconciliation output |
| 359 | - `es-estimated-tax` -- Modelo 130 computation (or fallback computation) |
| 360 | |
| 361 | **Outputs:** The final reviewer package. No downstream skill. |

| 365 | ## Section 9 -- Known gaps |
| 366 | |
| 367 | 1. PDF form filling is not automated. The reviewer uses the worksheets to fill official AEAT forms on the Sede Electrónica. |
| 368 | 2. E-filing is handled by the reviewer via AEAT Sede Electrónica (with certificado digital or Cl@ve), not by this skill. |
| 369 | 3. Payment execution is the client's responsibility; the skill only provides instructions and amounts. |
| 370 | 4. es-estimated-tax is a Q4 stub. Until it is fleshed out, Modelo 130 is computed using the standard formula (Art. 110 LIRPF). This is a redundancy, not a gap -- the formula is deterministic. |
| 371 | 5. Multi-year amortisation tracking assumes the prior year schedule is provided. If not, only current-year acquisitions are amortised. |
| 372 | 6. Rental income (rendimiento del capital inmobiliario) is out of scope. |
| 373 | 7. Capital gains (ganancias patrimoniales) are out of scope beyond noting them as other income. |
| 374 | 8. Imputación de rentas inmobiliarias (imputed income on empty properties) is out of scope. |
| 375 | 9. Modelo 720 (overseas assets declaration) is out of scope. |
| 376 | 10. The package is complete only for tax year 2025; 2026 appears only as prospective planning. |
| 377 | 11. País Vasco and Navarra foral regimes are out of scope -- territorio común (AEAT) only. |
| 378 | |
| 379 | ### Change log |
| 380 | - **v0.1 (April 2026):** Initial draft. Modelled on mt-return-assembly v0.1 adapted for Spain jurisdiction with four content skills (IVA Modelo 303, IRPF Modelo 100, RETA, Modelo 130). |

About
Final orchestrator skill that assembles the complete Spain filing package for Spain-resident self-employed individuals (autónomos). Consumes outputs from all Spain content skills (spain-vat-return for Modelo 303, es-income-tax for IRPF Modelo 100, es-social-contributions for RETA, es-estimated-tax for Modelo 130 pagos fraccionados) to produce a single unified reviewer package containing every worksheet, every form, every brief section, all cross-skill reconciliations, and the final action list with payment instructions, filing instructions, and next-year planning. This is the capstone skill that runs last and produces the final deliverable. MUST be loaded alongside all Spain content skills listed above. Spain full-year residents only. Autónomos (self-employed individuals) only.
