Use this skill whenever asked about Ecuador social security contributions (IESS), payroll, or personal income tax (Impuesto a la Renta) for a dependent worker, employer, or self-employed/voluntary affiliate. Trigger on phrases like "how much IESS do I pay", "aporte personal IESS", "aporte patronal", "9.45% IESS", "11.15% employer contribution", "fondos de reserva", "decimo tercero", "decimo cuarto", "Ecuador payroll cost", "retencion en relacion de dependencia", "Formulario 102", "Formulario 107", "planilla IESS", "afiliado voluntario", or any question about Ecuadorian social-insurance or wage-tax obligations. Also trigger when classifying bank-statement transactions that relate to IESS debits, SRI tax payments, planilla payments, fondos de reserva, or decimos from Banco Pichincha, Banco del Pacifico, Produbanco, Banco Guayaquil, or other Ecuadorian banks. This skill covers IESS employee/employer rates and their internal breakdown, IECE/SECAP levies, fondos de reserva, the SBU minimum-wage floor, decimo tercero/cuarto, utilidades, the FY2025 and FY2026 progressive income-tax tables, filing forms and deadlines, penalties, bank-statement classification patterns, and edge cases. ALWAYS read this skill before touching any Ecuador IESS, payroll, or income-tax work.

Contribution overview (full-time private-sector dependent worker)
| Component | Who pays | Rate | Base |
|---|---|---|---|
| IESS aporte personal | Employee (withheld) | 9.45% | Materia gravada [misalario.ec; PwC] |
| IESS aporte patronal (base) | Employer | 11.15% | Materia gravada [misalario.ec] |

| Fondos de reserva | Employer | 8.33% | Remuneration, from month 13 [misalario.ec; PwC] |
Arithmetic check: 9.45 + 11.15 = 20.60. Employer total per PwC presentation = 11.15 + 0.50 + 0.50 = 12.15 [PwC].
Conservative defaults
| Ambiguity | Default |
|---|---|
| Unknown worker type | Assume private-sector dependent worker (9.45% / 11.15%) |
| Employer rate basis in cost model | Use 11.15% base; add 1.00% (IECE+SECAP) for ~12.15% per PwC -- STATE the basis used |
| Worker under 12 months' service | Do NOT include 8.33% fondos de reserva |
| Unknown remuneration | Apply SBU floor (USD 470 in 2025 / USD 482 in 2026) |
| Unknown tax year | Use FY2025 table; flag FY2026 if period falls in 2026 |
| Unknown whether decimos/utilidades are in base | EXCLUDE them -- they are NOT materia gravada [PwC] |
Minimum viable -- worker type (private dependent / public / voluntary affiliate / self-employed), the tax/contribution period, and the monthly remuneration (materia gravada). Without the worker type and the period, STOP.
Recommended -- months of continuous service with the same employer (drives fondos de reserva eligibility), region (Coast/Galapagos vs Sierra/Amazon -- drives decimo cuarto deadline), and whether decimos are paid monthly or accumulated.
Ideal -- IESS planilla / aviso de entrada, Formulario 107 (annual employment-income certificate), bank statements showing IESS planilla debits and SRI tax payments, prior-year Formulario 102/102A.
Deterministic pre-classifier for Ecuadorian bank-statement transactions. Match by case-insensitive substring on the counterparty/reference. IESS contributions and income-tax payments are statutory personal/employer obligations -- they are NOT VAT-able supplies and EXCLUDE from any IVA (VAT) return.
How to read this table. In Ecuador, IESS planilla debits and SRI tax payments are usually paid by the employer/taxpayer via the bank's "pago de servicios" or "convenio de debito" facility. They are outgoing (DEBIT). Inbound IESS credits are pensions or loan disbursements, not contributions.
IESS contribution debits (planilla)

|---|---|---|
| IESS, INST ECUATORIANO SEGURIDAD SOCIAL | EXCLUDE -- IESS contribution | Monthly planilla (employee + employer) |
| PLANILLA IESS, APORTES IESS | EXCLUDE -- IESS contribution | Monthly planilla reference |
| APORTE PATRONAL, APORTE PERSONAL | EXCLUDE -- IESS contribution | Explicit aporte reference |
| FONDOS DE RESERVA, FONDO RESERVA | EXCLUDE -- IESS reserve fund | 8.33% from month 13 |
| SEGURIDAD SOCIAL | EXCLUDE -- IESS contribution | Generic reference |
IESS debits on specific Ecuadorian banks

| Pattern | Treatment | Notes |
|---|---|---|
| SRI, SERVICIO DE RENTAS INTERNAS | EXCLUDE -- tax payment, not IESS | Income tax or IVA |
| IMPUESTO A LA RENTA, FORM 102 | EXCLUDE -- income tax | Not a social contribution |
| RETENCION EN LA FUENTE | EXCLUDE -- withholding remittance | PIT withheld on payroll, not IESS |

Six bank-statement and payroll classifications for a hypothetical Quito-based SME and its employees. All amounts in USD. Computations reconcile to the cent.
Input line:
31.03.2025 ; PLANILLA IESS BANCO PICHINCHA ; DEBIT ; APORTES MARZO 2025 ; -247.20 ; USD
Reasoning: Worker earns USD 1,200/month materia gravada. Employee aporte personal = 1,200 x 9.45% = USD 113.40 [misalario.ec]. Employer aporte patronal (base) = 1,200 x 11.15% = USD 133.80 [misalario.ec]. The planilla debit combines both: 113.40 + 133.80 = USD 247.20. Matches "PLANILLA IESS" (pattern 3.1/3.2). Excludes from IVA.
Classification: EXCLUDE -- IESS contribution (employee USD 113.40 + employer USD 133.80 = USD 247.20).
Input: Monthly gross USD 1,200; annualised USD 14,400.
Reasoning:
Note: the income-tax base after deducting personal expenses/IESS is simplified here; in practice the employer projects annual taxable income net of allowable personal-expense deductions. PIT figure is illustrative.
Classification: Net pay approx USD 1,082.61/month; employer additionally bears 11.15% (USD 133.80) + IECE/SECAP + fondos de reserva (if past month 12).
Reasoning (PwC basis, employer side):
Decimo tercero (approx 1/12 = USD 100.00) and decimo cuarto (USD 470/12 = USD 39.17 in 2025) are additional labour costs but are NOT materia gravada [PwC; ecuadorlegalonline.com].
Classification: Employer statutory cost USD 245.76 on top of the USD 1,200 wage (worker past 12 months).
Input: Worker on the 2026 SBU of USD 482/month [Acuerdo MDT-2025-195].
Reasoning:
Classification: EXCLUDE IESS debit USD 99.29 combined; zero PIT.
Input line:
26.03.2026 ; SRI IMPUESTO RENTA FORM 102A ; DEBIT ; DECLARACION 2025 ; -624.00 ; USD
Reasoning: Matches "SRI" / "IMPUESTO RENTA" (pattern 3.3). This is the annual income-tax settlement (Formulario 102A), NOT an IESS contribution. USD 624 corresponds to the FY2025 cumulative tax at the top of the third bracket (taxable income USD 19,978) [SRI Res. NAC-DGERCGC24-00000041]. Exclude from IVA; do not classify as social security.
Classification: EXCLUDE -- SRI income-tax payment. NOT IESS.
Input line:
14.07.2025 ; IESS CONVENIO PAGO ; DEBIT ; PLANILLA + MORA ; -1,820.00 ; USD
Reasoning: Matches "IESS" (pattern 3.1) but the reference says "PLANILLA + MORA" and the amount is irregular. This likely combines unpaid contributions with mora patronal interest (Banco Central max conventional rate +4 points) and fines [IESS]. Principal cannot be separated from interest/fines without an IESS statement.
Classification: EXCLUDE from IVA. Flag for reviewer -- request IESS detalle to split contribution principal (deductible expense) from interest/fines (non-deductible).
Apply exactly as written when worker type, period and remuneration are known.

R-EC-IESS-1 -- Employer rate basis not specified
Trigger: a payroll-cost or net-pay computation where the user has not stated which employer rate to apply. Message: "The employer IESS rate is reported two ways: 11.15% (base, local Ecuadorian sources) or 12.15% (PwC, including 0.5% IECE + 0.5% SECAP). Confirm which basis the client wants before I model employer cost."
R-EC-IESS-2 -- Fondos de reserva on a worker under 12 months
Trigger: request to include 8.33% fondos de reserva for a worker with under one year of continuous service. Message: "Fondos de reserva are not owed until the 13th month of continuous service with the same employer [misalario.ec]. I will not include them for a worker under 12 months without reviewer confirmation of the start date."misalario.ec
R-EC-IESS-3 -- IESS mora patronal / arrears quantification
Trigger: client has unpaid IESS contributions. Message: "Mora patronal interest accrues at the Banco Central maximum conventional rate plus 4 points, plus fines and responsabilidad patronal [IESS].

R-EC-IESS-4 -- Special/disability sub-rates and the alleged extra 0.1%
Trigger: request relying on a special disability-pension sub-rate (a secondary source mentioned an additional ~0.1%).

R-EC-IESS-5 -- The 11.15% internal sub-breakdown
Trigger: a request that depends on the exact internal allocation of the 11.15% (IVM/Salud/Riesgos/Cesantia/SSC/admin). Message: "The internal sub-breakdown comes from a secondary Ecuadorian payroll source (tagline-soluciones), not directly from the official IESS Tasas de Aportacion PDF, which could not be parsed. **[RESEARCH GAP -- reviewer to confirm]** against iess.gob.ec before publishing the sub-allocation."tagline-soluciones

IESS payment deadline
The employer files and pays the monthly planilla (employee + employer + fondos de reserva) within 15 days after each month-end. Lateness triggers mora patronal.[IESS]
Mandatory affiliation from day one
All dependent workers must be affiliated (Aviso de Entrada) from the first day of work; there is no minimum income or hours threshold for mandatory affiliation.[IESS / AfiliacionIESS]
Decimo tercero and decimo cuarto
Decimo tercer sueldo = 1/12 of annual ordinary remuneration, payable by 24 December (or monthly if elected) [lexis.com.ec]. Decimo cuarto sueldo = one SBU per year (USD 470 in 2025; USD 39.17/month accumulated), payable by 15 March (Coast/Galapagos) or 15 August (Sierra/Amazon) [ecuadorlegalonline.com].[lexis.com.ec; ecuadorlegalonline.com]
Annual income-tax return
Formulario 102/102A is due in March of the following year, on a date set by the 9th digit of the taxpayer's RUC/cedula (window approx 10-28 March). Employees with only employment income and no other income may rely on employer withholding and Formulario 107 instead of filing 102 separately.[SRI; gob.ec]
T2-1
Trigger: any employer-cost model. Issue: local sources cite 11.15% base + separate IECE/SECAP; PwC consolidates to 12.15%. Action: confirm which presentation the client uses; state it explicitly in the working paper.
T2-2
Trigger: a report depending on the IVM/Salud/Riesgos/Cesantia/SSC/admin split. Issue: the split comes from a secondary source, not the official IESS PDF (which could not be parsed). Action: **[RESEARCH GAP -- reviewer to confirm]** against iess.gob.ec/documents/13718/54965/Tasasdeaportacion.pdf.
T2-3
Trigger: a model relying on an additional ~0.1%. Issue: referenced by a secondary source only, not independently confirmed. Action: **[RESEARCH GAP -- reviewer to confirm]**; do NOT include in headline rates.
T2-4
Trigger: worker near the 12-month mark. Issue: 8.33% begins only from month 13 of continuous service with the same employer. Action: confirm the exact start date before including.
T2-5
Trigger: unpaid contributions. Issue: interest at Banco Central max conventional rate +4 points, plus fines and employer liability for benefits paid in Health/Pensions/Work Risk/Cesantia. Action: do NOT quantify without an IESS statement; escalate.
T2-6
Trigger: decimo cuarto provision. Issue: deadline is 15 March (Coast/Galapagos) vs 15 August (Sierra/Amazon). Action: confirm the worksite region.
T2-7
Trigger: computations for periods in 2026. Issue: FY2026 SBU (USD 482) and the FY2026 income-tax table are officially confirmed but forward-looking. Action: confirm the period; cross-check the literal SRI resolution on sri.gob.ec.
