Key figures — Ecuador, 2025

Every figure is drawn from this skill and cited to its source.

PIT progressivity and indexation

PIT is progressive 0%-37% on net taxable income. The table is indexed annually to the urban CPI (INEC) at 30 November; the 2026 indexation was 1.0534712934405%.LRTI art. 36; SRI Resolution NAC-DGERCGC25-00000043

How to compute tax in any bracket

tax = (tax on base) + (net taxable income − bracket floor) × marginal rate. Then subtract the personal-expense rebate (see Section 1, Personal-Expense Rebate). Never compute tax directly in prose -- pass the chargeable figure to the deterministic engine.

Non-residents flat rate

25%PwC Worldwide Tax Summaries -- Ecuador Individual

Materia gravada base definition

Base = materia gravada (salary + habitual remuneration: commissions, overtime, etc.). Floor = 1 SBU. No upper ceiling.IESS Tasas de Aportación (as reported by EcuadorLegalOnline; misalario.ec). [RESEARCH GAP — the IESS official PDF was binary/unreadable; the 9.45% / 11.15% / 20.50% rates rely on EcuadorLegalOnline and misalario.ec, not the IESS document itself; fund-by-fund split (IVM/salud/riesgos/cesantía) not obtained — reviewer to confirm.]

Rebate formula

rebate = 18% × the lesser of (a) declared documented personal expenses, or (b) the canasta capSRI; Russell Bedford; HLB Ecuador; Buró Tributario

Minimum viable inputs

Bank statement for the full tax year (CSV, PDF, or pasted text), plus confirmation of (a) residency (resident vs non-resident / 183-day test), (b) regime (general vs RIMPE), and (c) number of dependents (for the gastos-personales rebate).

Recommended inputs

All facturas (sales and purchase invoices with RUC), IESS contribution / planilla records, prior-year Formulario 102, RUC registration showing regime, RIMPE category (Negocio Popular vs Emprendedor) if applicable.

Ideal inputs

Complete income and expenditure account, Anexo de Gastos Personales (APS) detail with documented facturas by category (vivienda, salud, educación, alimentación, vestimenta, turismo), 13th/14th salary records, withholding certificates (comprobantes de retención).

Refusal if minimum missing

SOFT WARN. No bank statement at all = hard stop. Bank statement without facturas = proceed with reviewer warning: "This Formulario 102 was produced from bank statement alone. The reviewer must verify that every deductible expense and every gasto personal claimed is supported by a valid factura with RUC, and that residency and regime are correctly determined."

R-EC-1 -- Residency unknown

Residency determines the entire computation: residents are taxed on worldwide income at the progressive 0%-37% table; non-residents pay a flat 25% on Ecuadorian-source income with no allowance. This skill cannot compute tax without resolving the 183-day test. Please confirm before proceeding.

R-EC-2 -- Companies / partnerships / sociedades

This skill covers natural persons (personas naturales) and self-employed individuals only. Sociedades, companies, and other legal entities file under the corporate regime (Impuesto a la Renta de Sociedades). Escalate to a licensed Ecuadorian contador.

R-EC-3 -- Cross-border / treaty cases

Worldwide income, foreign tax credits, double-tax treaties, and CAN Decision 578 (Andean Community) require specialised analysis. Out of scope. Escalate to a licensed Ecuadorian contador.

R-EC-4 -- Capital gains / property disposals / herencias

Gains on shares or real property, inheritance/gift tax, and asset disposals require separate analysis. Escalate to a licensed Ecuadorian contador.

R-EC-5 -- Arrears / SRI enforcement

Client has outstanding tax arrears or is subject to SRI enforcement. Interest on mora is variable (Banco Central 90-day reference rate, set quarterly) and a 20% recargo applies where the SRI detects the omission. Do not advise. Escalate immediately.

R-EC-6 -- IVA return requested

This skill covers income tax (Formulario 102/102A) only. For Ecuador IVA, use the ecuador-iva skill.

Exempt base and filing obligation

PIT is progressive 0%-37% on net taxable income (LRTI art. 36). The 2025 exempt base is USD 12,081 (SRI Resolution NAC-DGERCGC24-00000041); 2026 is USD 12,208 with the top 37% bracket starting at USD 109,956 (SRI Resolution NAC-DGERCGC25-00000043). Filing obligation: natural persons with gross income above the exempt base (USD 12,081 for 2025, ≈ USD 1,006.75/month) must file the annual return EVEN IF the rebate reduces tax to zero (SRI; Primicias).LRTI art. 36; SRI Resolution NAC-DGERCGC24-00000041; SRI Resolution NAC-DGERCGC25-00000043; SRI; Primicias

Taxable employment income definition

Taxable employment income = total labour compensation NET of employee IESS contributions (9.45%), and EXCLUDING the 13th (Christmas) and 14th (education) salaries, which are exempt. Employers compute monthly PIT withholding on projected annual taxable income (salary net of IESS, excluding 13th/14th) using the art. 36 table, less the projected personal-expense rebate, reconciled annually.LRTI; Código del Trabajo; PwC; Reglamento LRTI

Rebate formula

rebate = 18% × the lesser of (a) declared documented personal expenses, or (b) the canasta cap. Cap = 7 canastas with no dependents, scaling to 9/11/14/17/20 canastas for 1/2/3/4/5+ dependents. Canasta básica = USD 798.31 (Jan 2025) and USD 821.80 (Jan 2026). All gastos personales must be backed by facturas with the taxpayer's RUC/cédula. See Section 1 for the full multiplier table and [RESEARCH GAP] markers on the 2025 per-dependent caps.SRI; Russell Bedford; HLB Ecuador

Residency trigger and effects

Tax residency triggers at 183 days (consecutive or not) in a fiscal year, OR 183+ days over 12 months spanning two fiscal periods. Residents are taxed on worldwide income with a foreign tax credit (pay the Ecuadorian excess if Ecuador's rate is higher). Non-residents pay only on Ecuadorian-source income at a flat 25% withheld at source.SRI; LRTI art. 4.1; Russell Bedford

Fondos de Reserva and remittance deadline

Employer must also pay Fondos de Reserva at 8.33% of remuneration from the worker's 13th month of continuous service (Código del Trabajo). IESS contributions are remitted within 15 days following the worked month (EcuadorLegalOnline). [RESEARCH GAP — IESS official PDF unreadable; rates per EcuadorLegalOnline / misalario.ec.]Código del Trabajo; EcuadorLegalOnline

Décimo Tercer Sueldo

= 1/12 of total remuneration earned 1 Dec–30 Nov; paid by 24 Dec. EXEMPT from PIT; NOT in IESS base.Código del Trabajo; PwC; EcuadorLegalOnline

Décimo Cuarto Sueldo

= 1 SBU (USD 470 in 2025; USD 482 in 2026); paid by 15 Mar (Costa/Insular) or 15 Aug (Sierra/Amazonía). EXEMPT from PIT.Código del Trabajo; PwC; EcuadorLegalOnline

RIMPE filing timing and applicability

RIMPE income tax is declared in May of the following year (e.g. 2025 RIMPE return due May 2026), by ninth digit. Apply RIMPE ONLY if the taxpayer is registered in RIMPE and within the band.SRI RIMPE; JEZL; Bloomberg Línea; Primicias

Home office apportionment

For a self-employed person working from home, apportion electricity, water, internet, rent to the business-use proportion. Must have facturas with RUC. Conservative default: 0% deduction until reviewer confirms the apportionment basis.

Motor vehicle business use

Only the business-use percentage of fuel, insurance, maintenance is deductible; requires a mileage log. Conservative default: 0% business use until a log is provided.

Phone/internet mixed use

Business-use portion only. Conservative default: 0% deduction until business percentage confirmed.

Gastos personales documentation and dependents

The rebate depends on documented facturas by category and on the number of dependents (drives the canasta multiplier). Flag for reviewer to confirm dependents and that each factura carries the taxpayer's RUC/cédula and falls in an allowed category. [RESEARCH GAP — 2025 per-dependent caps to confirm.]

Regime choice

Confirm RUC registration and revenue band. RIMPE is mandatory/elective per the taxpayer's registration; do not assume. Flag for reviewer where revenue is near the USD 20,000 (Negocio Popular) or USD 300,000 (Emprendedor) thresholds.

Foreign income and treaty relief

Worldwide income with foreign tax credit; treaty relief and CAN Decision 578 may apply. Flag for reviewer in any cross-border case.

Rendered from the canonical facts model. General reference only — confirm with a qualified professional before acting.

Tier 2 (research-verified). NOT yet accountant-verified. The 2026 PIT table is read verbatim from the official SRI Resolution NAC-DGERCGC25-00000043 PDF (high confidence). The 2025 table and several social-security / gastos-personales figures rely on Big-4 (PwC) and reputable Ecuadorian sources (JEZL, Russell Bedford, HLB Ecuador) rather than line-by-line re-extraction of the original SRI resolutions; those points carry inline [RESEARCH GAP — reviewer to confirm] markers.

Reasoning: Professional fee. If the professional is IVA-registered, USD 1,150 includes 15% IVA → net = USD 1,000 (renta gravada); USD 150 is IVA collected (a liability to the SRI, excluded from income). If not IVA-registered, the full USD 1,150 is income.

Classification: Renta gravada = USD 1,000 (IVA-registered) or USD 1,150 (not registered). IVA USD 150 excluded.

Example 2 -- Self-Employed Annual PIT with Rebate (2025)

Input: Resident professional, net taxable income (after deductible business costs and IESS) = USD 30,000. Documented personal expenses ≥ the cap, no dependents.

Reasoning:

  • USD 30,000 falls in the 26,422–34,770 bracket (15%).
  • Tax = 1,398 + (30,000 − 26,422) × 15% = 1,398 + 3,578 × 0.15 = 1,398 + 536.70 = USD 1,934.70.
  • Personal-expense rebate (no dependents): 18% × min(declared expenses, 7 canastas = 5,588.17) = 5,588.17 × 0.18 = USD 1,005.87.
  • Tax after rebate = 1,934.70 − 1,005.87 = USD 928.83.

Classification: Impuesto causado USD 1,934.70; rebaja USD 1,005.87; tax due USD 928.83 (before withholding credits).

Example 3 -- Employee Monthly IESS Withholding (2025)

Input line: 30/04/2025 ; GUAYAQUIL ; ROL DE PAGOS ; EMPLEADOR XYZ SA ; SUELDO ABRIL ; +1,358.25 ; USD

Reasoning: Gross monthly salary USD 1,500. Employee IESS aporte personal = 9.45% × 1,500 = USD 141.75. Net deposited to the worker = 1,500 − 141.75 = USD 1,358.25 (before any PIT withholding). The 13th/14th salaries are paid separately and are exempt; they are NOT part of the IESS base.

Classification: IESS employee USD 141.75; taxable employment base (this month) USD 1,358.25 before PIT withholding.

Example 4 -- Non-Resident Ecuadorian-Source Fee

Input line: 10/06/2025 ; PICHINCHA ; TRANSFERENCIA ; CLIENTE EC ; SERVICIOS PRESTADOS EN ECUADOR ; +10,000.00 ; USD

Reasoning: Payee is a non-resident (183-day test NOT met). Ecuadorian-source income is taxed at a flat 25% withheld at source, with no brackets and no personal allowance (PwC). Tax = 10,000 × 25% = USD 2,500.

Classification: Flat 25% non-resident withholding = USD 2,500. No rebate, no table.

Example 5 -- RIMPE Negocio Popular (Small Self-Employed)

Input: Resident natural person, gross annual revenue USD 18,000, registered in RIMPE as Negocio Popular.

Reasoning: Negocio Popular ceiling is gross annual income ≤ USD 20,000 (SRI RIMPE; JEZL). Negocios Populares pay a fixed-fee table (USD 0 / 5 / 15 / 35 / 60 across revenue bands), not the progressive PIT table. [RESEARCH GAP — the exact band thresholds mapping revenue to each fixed fee were not extracted from the SRI RIMPE resolution; reviewer to confirm which fixed fee applies to USD 18,000.] RIMPE income tax is declared in May of the following year (SRI Boletín NAC-COM-25-0020).

Classification: RIMPE Negocio Popular fixed fee (USD 0/5/15/35/60) -- exact figure pending reviewer confirmation of the band. NOT the art. 36 table.

Example 6 -- IESS for Self-Employed Voluntary Affiliate

Input line: 05/02/2025 ; PRODUBANCO ; DEBITO ; IESS ; APORTE VOLUNTARIO ENERO ; -96.35 ; USD

Reasoning: Self-employed individual not under labour dependency is a voluntary/independent IESS affiliate at 20.50% on declared income, minimum 1 SBU (USD 470 in 2025), paid entirely by the individual. On the SBU floor: 470 × 20.50% = USD 96.35/month.

Classification: IESS voluntary contribution USD 96.35 (on SBU floor). Deductible from the self-employed's income base, not a business expense line.

Example 7 -- Own-Account Transfer (Exclude)

Input line: 15/05/2025 ; PICHINCHA ; TRANSFERENCIA ENTRE CUENTAS PROPIAS ; AHORRO ; ; -2,000.00 ; USD

Reasoning: Transfer between the taxpayer's own accounts. Neither income nor expense. Exclude entirely.

Classification: EXCLUDE.

Section 5 -- Tier 1 Rules (When Data Is Clear)

5.1 Progressive PIT, Exempt Base and Filing Obligation

  • Exempt base and filing obligation — PIT is progressive 0%-37% on net taxable income (LRTI art. 36). The 2025 exempt base is USD 12,081 (SRI Resolution NAC-DGERCGC24-00000041); 2026 is USD 12,208 with the top 37% bracket starting at USD 109,956 (SRI Resolution NAC-DGERCGC25-00000043). Filing obligation: natural persons with gross income above the exempt base (USD 12,081 for 2025, ≈ USD 1,006.75/month) must file the annual return EVEN IF the rebate reduces tax to zero (SRI; Primicias). (LRTI art. 36; SRI Resolution NAC-DGERCGC24-00000041; SRI Resolution NAC-DGERCGC25-00000043; SRI; Primicias)

5.2 Taxable Employment Income

  • Taxable employment income definition — Taxable employment income = total labour compensation NET of employee IESS contributions (9.45%), and EXCLUDING the 13th (Christmas) and 14th (education) salaries, which are exempt. Employers compute monthly PIT withholding on projected annual taxable income (salary net of IESS, excluding 13th/14th) using the art. 36 table, less the projected personal-expense rebate, reconciled annually. (LRTI; Código del Trabajo; PwC; Reglamento LRTI)

5.3 Personal-Expense Rebate (Rebaja por Gastos Personales)

  • Rebate formula — rebate = 18% × the lesser of (a) declared documented personal expenses, or (b) the canasta cap. Cap = 7 canastas with no dependents, scaling to 9/11/14/17/20 canastas for 1/2/3/4/5+ dependents. Canasta básica = USD 798.31 (Jan 2025) and USD 821.80 (Jan 2026). All gastos personales must be backed by facturas with the taxpayer's RUC/cédula. See Section 1 for the full multiplier table and [RESEARCH GAP] markers on the 2025 per-dependent caps. (SRI; Russell Bedford; HLB Ecuador)

5.4 Residency and Worldwide Income

  • Residency trigger and effects — Tax residency triggers at 183 days (consecutive or not) in a fiscal year, OR 183+ days over 12 months spanning two fiscal periods. Residents are taxed on worldwide income with a foreign tax credit (pay the Ecuadorian excess if Ecuador's rate is higher). Non-residents pay only on Ecuadorian-source income at a flat 25% withheld at source. (SRI; LRTI art. 4.1; Russell Bedford)

5.5 IESS Contributions

  • Fondos de Reserva and remittance deadline — Employer must also pay Fondos de Reserva at 8.33% of remuneration from the worker's 13th month of continuous service (Código del Trabajo). IESS contributions are remitted within 15 days following the worked month (EcuadorLegalOnline). [RESEARCH GAP — IESS official PDF unreadable; rates per EcuadorLegalOnline / misalario.ec.] (Código del Trabajo; EcuadorLegalOnline)

5.6 13th and 14th Salaries

  • Décimo Tercer Sueldo — = 1/12 of total remuneration earned 1 Dec–30 Nov; paid by 24 Dec. EXEMPT from PIT; NOT in IESS base. (Código del Trabajo; PwC; EcuadorLegalOnline)
  • Décimo Cuarto Sueldo — = 1 SBU (USD 470 in 2025; USD 482 in 2026); paid by 15 Mar (Costa/Insular) or 15 Aug (Sierra/Amazonía). EXEMPT from PIT. (Código del Trabajo; PwC; EcuadorLegalOnline)

Test Suite

Test 1 -- Self-employed, mid-range income, full rebate (2025). Input: Resident, net taxable income USD 30,000, no dependents, documented personal expenses ≥ cap. Expected: Impuesto causado = 1,398 + (30,000 − 26,422) × 15% = USD 1,934.70. Rebate = 5,588.17 × 18% = USD 1,005.87. Tax due = USD 928.83.

Test 2 -- Income at the exempt base (2025). Input: Resident, net taxable income USD 12,081. Expected: USD 0 tax (top of the 0% band). Filing still REQUIRED because gross income reaches the threshold.

Test 3 -- Top bracket entry (2026). Input: Resident, net taxable income USD 109,956. Expected: Cumulative tax = USD 24,572 at the start of the 37% band (next dollar taxed at 37%).

Test 4 -- Non-resident flat 25%. Input: Non-resident, Ecuadorian-source income USD 10,000. Expected: Tax = 10,000 × 25% = USD 2,500. No table, no rebate.

Test 5 -- Employee monthly IESS (2025). Input: Gross monthly salary USD 1,500, private-sector dependent worker. Expected: Employee IESS = 1,500 × 9.45% = USD 141.75; employer IESS = 1,500 × 11.15% = USD 167.25; total IESS = USD 309.00 (20.60%).

Test 6 -- Self-employed voluntary IESS on SBU floor (2025). Input: Voluntary/independent affiliate at the SBU floor (USD 470). Expected: Monthly contribution = 470 × 20.50% = USD 96.35.

Test 7 -- RIMPE band check. Input: Resident, gross annual revenue USD 250,000. Expected: Within the Emprendedor band (USD 20,000.01–300,000); taxed 0%-2% marginal on gross under RIMPE if registered -- NOT the art. 36 table.

PROHIBITIONS

  • NEVER apply the progressive table without confirming residency -- non-residents pay a flat 25% with no allowance
  • NEVER compute the impuesto causado in prose -- pass the base imponible to the deterministic engine
  • NEVER include the 13th or 14th salary in taxable income or in the IESS base
  • NEVER apply the 9.45/11.15 split to a self-employed person not under labour dependency -- use 20.50% voluntary
  • NEVER allow fines, penalties, interés por mora, or income tax itself as a deduction
  • NEVER include IVA collected on sales in renta gravada for IVA-registered taxpayers
  • NEVER claim a gasto personal or business deduction without a factura carrying the taxpayer's RUC/cédula
  • NEVER exceed the canasta cap on the personal-expense rebate -- it is 18% of the LESSER value
  • NEVER apply RIMPE unless the taxpayer is registered in RIMPE and within the revenue band
  • NEVER present a figure marked [RESEARCH GAP] as confirmed -- escalate to the reviewer
  • NEVER present tax calculations as definitive -- always label as estimated
