Six bank statement classifications for a hypothetical Spanish self-employed web developer.
Input line:
30.04.2025 ; TGSS TESORERIA GENERAL ; ADEUDO ; CUOTA AUTONOMOS ABR 2025 ; -425.85 ; EUR
Reasoning: Matches "TGSS" + "CUOTA AUTONOMOS" (pattern 3.1). Amount EUR 425.85 = Tranche 10 minimum base (EUR 1,356.21) x 31.40%. Monthly RETA cuota for April 2025, debited on last business day of April. Exclude from VAT.
Classification: EXCLUDE -- RETA cuota. 100% deductible as gasto deducible in IRPF.
Input line:
31.03.2025 ; TGSS ; ADEUDO ; CUOTA TARIFA PLANA MAR ; -80.00 ; EUR
Reasoning: Matches "TGSS" (pattern 3.1). Amount EUR 80.00 = tarifa plana flat rate. New autonomo in first 12 months. Covers all contingencies.
Classification: EXCLUDE -- tarifa plana RETA cuota. Deductible (EUR 80 x 12 = EUR 960/year).
Input line:
25.09.2025 ; TGSS REGULARIZACION ; ADEUDO ; COMPLEMENTO CUOTAS 2024 ; -2,413.54 ; EUR
Reasoning: Matches "TGSS REGULARIZACION" (pattern 3.2). After 2024 IRPF filing, TGSS determined actual income placed the autonomo in a higher tranche than the provisional base used. This is the additional cuotas demanded. Due by last day of month following notification.
Classification: EXCLUDE -- RETA regularisation demand. Deductible in 2025 (year paid, not 2024).
Input line:
15.10.2025 ; TGSS DEVOLUCION ; ABONO ; DEVOLUCION CUOTAS 2024 ; +1,907.45 ; EUR
Reasoning: Matches "TGSS DEVOLUCION" (pattern 3.3). TGSS refunding excess cuotas because actual income was in a lower tranche. This is a CREDIT. Taxable as income in the IRPF year received (2025).
Classification: EXCLUDE from VAT. Taxable income in 2025 IRPF (refund of previously deducted cuotas).
Input line:
20.04.2025 ; AGENCIA TRIBUTARIA ; ADEUDO ; PAGO FRACCIONADO IRPF ; -1,500.00 ; EUR
Reasoning: Matches "AGENCIA TRIBUTARIA" (pattern 3.5). This is a quarterly IRPF instalment (pago fraccionado), NOT a social contribution. Do not classify as RETA.
Classification: EXCLUDE -- income tax. NOT RETA.
Input line:
30.04.2025 ; TGSS REGIMEN GENERAL ; ADEUDO ; SS EMPLEADOS ABR ; -2,800.00 ; EUR
Reasoning: Matches "TGSS REGIMEN GENERAL" (pattern 3.6). This is the employer's social security obligation for their employees under the General Regime. It is NOT the autonomo's own RETA cuota.
Classification: EXCLUDE -- employer SS for employees. Not the autonomo's personal RETA contribution.

Trigger: Client works as employee (Regimen General) and self-employed (RETA) simultaneously. Issue: Must pay into both regimes. Reduction in RETA base may apply if combined contributions exceed thresholds. Potential 50% refund of excess. Action: Flag for reviewer -- case-specific calculation required.
Trigger: Client aged 47+ wants specific base election. Issue: Transitional provisions from pre-2023 system may restrict base choice. Action: Flag for reviewer.
Trigger: TGSS demands significant additional cuotas (estimated tranche far below actual). Issue: Payment due by last day of month following notification. Aplazamiento possible. Action: Flag for reviewer to advise on aplazamiento and whether income estimate was reasonable.
Trigger: Client registers mid-month. Issue: First month cuota pro-rated from date of alta. Tarifa plana runs from exact alta date, not first of month. Action: Confirm exact alta date.
Trigger: First-year income exceeded SMI. Issue: Extension denied. From month 13, full tranche-based cuota applies. Action: Confirm income level and transition to full cuota.
