Tax authority attitude to planningThe Agencia Estatal de Administración Tributaria (AEAT) accepts legitimate planning (economía de opción). Spain has a general anti-avoidance rule under Art. 15 LGT (conflicto en la aplicación de la norma tributaria): arrangements that are unusual or improper and whose principal purpose is to obtain a tax advantage can be disregarded. Additionally, Art. 16 LGT covers simulación (sham transactions).

Régimen de Estimación Directa

Régimen de Estimación Directa table

MethodDetail
Estimación Directa Normal (EDN)Full accounting, actual expenses, for turnover > EUR 600,000
Estimación Directa Simplificada (EDS)Actual expenses + 5% provisión de gastos de difícil justificación (max EUR 2,000/year). For turnover ≤ EUR 600,000.
Estimación Objetiva (módulos)Fixed tax based on objective indicators (square meters, employees, vehicles). Limited activities. Being phased out for many sectors.

Most autónomos use EDS. The automatic 5% provisión (up to EUR 2,000) is often forgotten -- it applies even if you cannot justify specific expenses.

DeductionLegislationNotes

Provisión gastos difícil justificaciónIRPF Art. 30.2.4ª5% of rendimientos netos, max EUR 2,000/year. Automatic in EDS -- no receipts needed.

Section 4 -- Capital Allowances Optimization

Legislation: IRPF Art. 29; RIRPF Art. 4 + simplified depreciation table

Simplified Depreciation Table (Estimación Directa Simplificada)

Simplified Depreciation Table

Asset categoryMaximum annual rateMaximum years
Buildings (commercial)3%68
Plant, machinery, tools12%18
Furniture10%20
IT equipment (hardware/software)26%10
Vehicles16%14
Other assets10%20

Libertad de Amortización (Free Depreciation)

  • Free depreciation for low-value assets — Available for assets of reduced value: items under EUR 300 can be freely depreciated (immediately expensed) up to EUR 25,000/year total. (IS Art. 12.3 (for companies); IRPF applies similar principles for small businesses.)

Timing Strategy

Purchase IT equipment (26% rate) in January to maximize the first-year deduction (full 26%). A December purchase gives only 1/12th of the annual rate.

Section 5 -- Loss Utilization

  • Legislation — IRPF Art. 48-49 (IRPF Art. 48-49)

Loss Utilization table (IRPF Art. 48-49)

ReliefDetail
Offset against general baseLosses from economic activities (rendimientos de actividades económicas) can offset other income in the general base (employment, rental) in the same year.
Carry-forwardUnused losses carry forward for 4 years against future income of the same category.
No carry-backSpain does not allow loss carry-back for IRPF.
Base del ahorro offsetCapital losses can only offset capital gains (base del ahorro). If capital losses exceed gains, up to 25% of the excess can offset positive general income.
Compensación between basesNegative rendimientos del capital mobiliario can offset up to 25% of positive ganancias patrimoniales, and vice versa.

Strategy

In the start-up phase, maximize deductible expenses to create losses. These offset any employment or rental income in the same year, then carry forward for 4 years. Plan to use them before they expire.

Section 6 -- Timing Strategies

Timing Strategies table

StrategyDetail
Defer invoicingUnder estimación directa, income is recognized on accrual basis. However, cash flow timing affects IVA obligations. For módulos, timing of invoices is irrelevant.
Accelerate expensesPrepay insurance premiums, professional subscriptions, training before 31 December.
Plan de pensiones contributionsMaximize contributions before 31 December. Reduces base imponible general directly.
Ganancias/pérdidas patrimoniales timingRealize capital losses before year-end to offset capital gains. Defer gains to next year if possible. Beware the 2-month anti-wash rule (no repurchase of same/similar securities within 2 months).
Retenciones managementAutónomos apply 15% IRPF withholding on invoices to professionals/companies (7% in first 3 years). Ensure correct rate to avoid overpaying during the year.
Matrimonial tax choiceMarried couples can file jointly (declaración conjunta) or separately. Compare both: joint filing benefits when one spouse has no/low income (EUR 3,400 additional mínimo personal).
Módulos exit timingIf leaving módulos for estimación directa, time the switch at the start of the year. Mid-year switches can create complications.

Section 7 -- VAT Optimization (IVA)

  • Legislation — Ley 37/1992 del IVA (Ley 37/1992 del IVA)

VAT Optimization table (Ley 37/1992 del IVA)

StrategyDetail
Régimen General vs SimplificadoGeneral: quarterly returns (Modelo 303). Simplificado: available for módulos activities, fixed quota.
Recargo de EquivalenciaFor retail traders buying from wholesalers: no IVA returns needed, wholesaler charges RE surcharge. Simplifies compliance but eliminates input IVA recovery.
Criterio de Caja (cash basis IVA)Pay output IVA only when collected from clients (not when invoiced). Available if turnover ≤ EUR 2m. Must opt in.
IVA deducible on vehicles50% of IVA on vehicle purchase/lease is deductible by default. 100% if exclusive business use is proven (difficult -- requires documentation).
Pro rata for mixed activitiesIf performing both IVA-taxable and IVA-exempt activities, optimize the pro rata calculation to maximize input IVA recovery.
Modelo 390 (annual summary)Review the annual summary to ensure no input IVA has been missed.

Section 8 -- Social Security Optimization

  • Legislation — LGSS (Real Decreto Legislativo 8/2015); RD-Ley 13/2022 (progressive RETA system) (LGSS (Real Decreto Legislativo 8/2015); RD-Ley 13/2022 (progressive RETA system))

Progressive Cuota de Autónomos (from 2023, phased through 2025)

From 2025/2026, autónomo contributions are based on real net income brackets:

Progressive Cuota de Autónomos table

Net monthly income (EUR)Approximate monthly cuota (2025)
≤ 670~EUR 200
671 -- 900~EUR 220
901 -- 1,166.70~EUR 260
1,166.71 -- 1,300~EUR 290
1,300 -- 1,500~EUR 350
1,500 -- 1,700~EUR 370
1,700 -- 1,850~EUR 390
1,850 -- 2,030~EUR 400
> 4,050~EUR 530

Optimization Strategies

Optimization Strategies table

StrategyDetail
Tarifa plana (flat rate)New autónomos: EUR 80/month for first 12 months (extendable to 24 months if income remains below minimum wage).
Income bracket managementThe progressive system means lower reported income = lower cuota. But this reduces future pension.
Regularización anualRETA contributions are regularized annually based on actual income reported in IRPF. Overpayments are refunded, underpayments are billed.
Cese de actividad (unemployment)Autónomos contribute to the cese de actividad fund. This provides unemployment-like benefits for 2-12 months. Ensure it is correctly configured.
Pluriactividad (dual activity)If simultaneously employed (régimen general) and autónomo (RETA), you may be entitled to a refund of excess contributions if combined bases exceed the contribution ceiling. Apply via Modelo 190.

Section 10 -- Red Lines

Red Lines table

RiskDetail
Conflicto en la aplicación de la norma (Art. 15 LGT)Unusual or improper arrangements principally aimed at tax advantage can be recharacterized. No penalty, but unpaid tax + interest.
Simulación (Art. 16 LGT)Sham transactions: penalty of 50-100% of avoided tax + interest.
Economía sumergidaUndeclared income is criminal if > EUR 120,000/year (Art. 305 Código Penal). Prison sentences of 1-5 years.
Factura falsaIssuing or using false invoices: criminal under Art. 310 CP (1-5 years) and Art. 305 CP.
Anti-wash ruleCannot deduct capital losses if the same or substantially similar securities are repurchased within 2 months (Ley IRPF Art. 33.5.f).
Tarifa plana abuseRe-registering as a new autónomo to re-claim the tarifa plana after a short cessation period. AEAT monitors gaps < 2-3 years.
Vinculación (related party transactions)Transactions between autónomo and own SL (or family SL) must be at arm's length. Art. 18 Ley IS.
CCAA deduction eligibilityAutonomous community deductions require actual residence in that community. Moving solely for tax benefits (particularly to Madrid) is scrutinized if not genuine.
