[RESEARCH GAP — reviewer to confirm] The precise per-department allocation of the employer Accidentes/EMA/IVS split may historically have varied by department; only the headline totals (4.83% / 10.67% / 15.50%) are firmly confirmed by IGSS and Banco Industrial. Confirm the line-by-line split against the current Junta Directiva acuerdo for the employer's department.

Conservative defaults

Ambiguity	Default
Unknown ordinary salary vs bono split	Treat the Q250 bono separately; apply IGSS only to ordinary salary
Unknown circumscription (C1 vs C2)	Ask -- do not assume; min-wage floor differs
Unknown employer worker count	Assume IGSS registration is required (threshold is 1+ worker)
Unknown whether ISR deductions apply	Apply the Q48,000 fixed personal deduction only; do not assume IVA credit
Ambiguous IGSS vs penalty debit	Classify as IGSS contribution; flag for reviewer
Minimum-wage worker, 2026+	Flag Decreto 13-2026 ISR exemption — escalate to reviewer

Section 2 -- Required inputs and refusal catalogue

Required inputs

• Minimum viable input — Monthly ordinary salary (Q), and whether the worker earns at or above minimum wage. Without the ordinary salary figure, STOP. Do not compute IGSS or ISR.

Recommended -- circumscription (C1 = Department of Guatemala; C2 = rest of country), economic activity (non-agri / agri / maquila), the Q250 bonificación incentivo amount actually paid, and the worker's other documented deductions (IGSS, life insurance, donations, IVA credit).

Ideal -- IGSS planilla, SAT-1431 employee deduction declaration, prior-year constancia de retención, and bank statements showing IGSS and SAT debits.

Refusal catalogue

• R-GT-1 -- Ordinary salary unknown — Trigger: monthly ordinary salary not provided. Message: "The monthly ordinary salary is mandatory for IGSS and ISR computation. IGSS applies to ordinary salary excluding the Q250 bonificación incentivo, and ISR depends on annualised taxable income. Cannot proceed without this figure."
• R-GT-2 -- IGSS arrears / mora — Trigger: employer has unpaid IGSS contributions. Message: "IGSS late-payment surcharge (recargo por mora) uses the maximum simple interest rate set annually by the Junta Monetaria, plus a 5% administrative-cost surcharge on a formal aviso de cobro (capped at Q3,000). Do not quantify arrears without an IGSS statement. Escalate to a licensed Guatemalan accountant."
• R-GT-3 -- Pension / maximum-insurable-salary questions — Trigger: client asks about the IGSS IVS pension benefit ceiling or maximum insurable salary. Message: "The exact current maximum insurable salary / IVS pension ceiling is [RESEARCH GAP — reviewer to confirm] and was not confirmed from an authoritative source. Do not state a figure. Escalate to a licensed accountant and confirm with IGSS."
• R-GT-4 -- Minimum-wage ISR exemption (Decreto 13-2026) — Trigger: worker earns minimum wage in 2026 onward. Message: "Decreto 13-2026 exempts minimum-wage workers from ISR withholding and redefines the personal deduction formulaically. Transitional rules apply for 2026 (extraordinary Q3,024 deduction). Confirm publication date and the worker's exact wage with a licensed accountant before applying."
• R-GT-5 -- Department-specific IGSS split — Trigger: client requires the precise Accidentes/EMA/IVS allocation for a specific department. Message: "Only the headline IGSS totals (4.83% / 10.67% / 15.50%) are firmly confirmed. The per-department split is [RESEARCH GAP — reviewer to confirm]. Escalate to a licensed accountant."

Section 3 -- Payment pattern library

This is the deterministic pre-classifier for bank statement transactions related to payroll, social security, and income tax. When a transaction matches a pattern below, apply the treatment directly. Do not second-guess.

How to read this table. Match by case-insensitive substring on the counterparty/reference as it appears in the bank statement. IGSS and ISR payments EXCLUDE from any IVA (VAT) return — they are statutory payroll obligations, not taxable supplies.

Section 4 -- Worked examples

Six bank-statement / payroll classifications for a hypothetical Guatemalan employer and employee (non-agricultural, Department of Guatemala, C1). All amounts in Quetzales (Q). IGSS applies only to ordinary salary, excluding the Q250 bono.

Example 1 -- IGSS employee withholding on an above-minimum salary (Banco Industrial)

Input line: 31/01/2026 ; IGSS PLANILLA ; DEBITO ; CUOTA LABORAL ENERO ; -241.50 ; GTQ

Reasoning: Matches "IGSS PLANILLA" / "CUOTA LABORAL" (patterns 3.1). Ordinary salary Q5,000.00. Employee IGSS = 4.83% × Q5,000.00 = Q241.50. The Q250 bono is excluded from the base. Exclude from IVA. This is the employee's statutory withholding.

Classification: EXCLUDE from IVA -- IGSS employee contribution (cuota laboral).

Example 2 -- Employer IGSS + parafiscal cost on the same salary

Input line: 31/01/2026 ; INSTITUTO GUATEMALTECO DE SEGURIDAD SOCIAL ; DEBITO ; CUOTA PATRONAL ENERO ; -633.50 ; GTQ

Reasoning: Matches "INSTITUTO GUATEMALTECO DE SEGURIDAD SOCIAL" (pattern 3.1). On ordinary salary Q5,000.00: employer IGSS = 10.67% × Q5,000.00 = Q533.50; INTECAP 1% = Q50.00; IRTRA 1% = Q50.00. The IGSS line here is Q533.50; if INTECAP/IRTRA appear together with IGSS the total is Q633.50. Check: Q533.50 + Q50.00 + Q50.00 = Q633.50. Exclude from IVA — employer payroll cost.

Classification: EXCLUDE from IVA -- employer IGSS + INTECAP + IRTRA (cuota patronal + parafiscal).

Example 3 -- ISR monthly withholding to SAT (NOT IGSS)

Input line: 14/02/2026 ; SAT RETENISR ; DEBITO ; SAT-1331 ISR RENTAS TRABAJO ; -989.63 ; GTQ

Reasoning: Matches "SAT RETENISR" / "SAT-1331" (pattern 3.3). This is ISR income-tax withholding, NOT IGSS. For a worker on Q25,000/month ordinary salary (annual salary Q300,000): annual IGSS deduction = 4.83% × Q300,000 = Q14,490.00; less fixed personal deduction Q48,000.00 → annual taxable income = Q300,000 − Q14,490 − Q48,000 = Q237,510.00, within bracket 1 (5%). Annual ISR = 5% × Q237,510.00 = Q11,875.50; monthly retención ≈ Q11,875.50 / 12 = Q989.63. Exclude from IVA. This is income tax, not social security.

Classification: EXCLUDE from IVA -- ISR withholding (SAT). NOT IGSS.

Example 4 -- Salary outgoing including bono incentivo

Input line: 30/01/2026 ; JUAN PEREZ NOMINA ; DEBITO ; SALARIO + BONO 250 ENERO ; -5,008.50 ; GTQ

Reasoning: Matches "NOMINA" / "BONO 250" (pattern 3.4). Net pay to the worker on a Q5,000.00 ordinary salary: gross ordinary Q5,000.00, less employee IGSS Q241.50 = Q4,758.50, plus Q250.00 bono incentivo = Q5,008.50 (before any ISR — none due here, salary is below the Q4,000/month exempt-equivalent only on the bono-excluded base; annual taxable Q5,000×12 − IGSS − Q48,000 = Q60,000 − Q2,898 − Q48,000 = Q9,102, ISR 5% = Q455.10/yr ≈ Q37.93/mo, withheld separately). The bono is excluded from IGSS; the salary line is a payroll expense, not a contribution.

Classification: EXCLUDE from IVA -- payroll expense (salary + bono incentivo). NOT a contribution.

Example 5 -- IGSS benefit received (subsidio, not a contribution)

Input line: 12/03/2026 ; IGSS SUBSIDIO ; CREDITO ; INCAPACIDAD TEMPORAL ; +1,800.00 ; GTQ

Reasoning: Matches "IGSS SUBSIDIO" / "INCAPACIDAD" (pattern 3.5). This is an IGSS sickness/maternity benefit RECEIVED, not a contribution paid. Do not confuse inbound IGSS credits with outbound contribution debits. Exclude from IVA. Not an employer cost or employee withholding.

Classification: EXCLUDE from IVA -- IGSS benefit received. NOT a contribution.

Example 6 -- Ambiguous IGSS debit (arrears / mora)

Input line: 20/04/2026 ; IGSS ; DEBITO ; AVISO DE COBRO RECARGO MORA ; -3,520.00 ; GTQ

Reasoning: Matches "IGSS" (pattern 3.1) but the reference says "AVISO DE COBRO RECARGO MORA." This includes mora interest (Junta Monetaria maximum simple rate) and possibly the 5% administrative-cost surcharge (capped at Q3,000). Cannot separate contribution principal from penalty without an IGSS statement. Flag for reviewer.

Classification: EXCLUDE from IVA. Flag for reviewer -- request IGSS breakdown to split contribution principal from mora/surcharge (penalties are not a normal deductible payroll contribution).

Section 5 -- Tier 1 rules

These rules apply when payroll data is clear and all required inputs are available. Apply exactly as written.

Rule 1 -- IGSS base excludes the bono incentivo

• IGSS computation formula — IGSS_employee = 4.83% x ordinary_salary IGSS_employer = 10.67% x ordinary_salary (IGSS only) parafiscal = 2.00% x ordinary_salary (INTECAP 1% + IRTRA 1%, employer only) employer_total_cost = 12.67% x ordinary_salary (Decreto 37-2001)

Rule 2 -- Employee never pays INTECAP or IRTRA

• Employee cuota laboral scope — The cuota laboral is 4.83% only. INTECAP (1%) and IRTRA (1%) are employer-only parafiscal levies. Never deduct them from the employee.

Rule 3 -- Combined IGSS headline

• Combined IGSS headline rate — Employee 4.83% + employer IGSS 10.67% = 15.50% combined IGSS. INTECAP + IRTRA sit on top of the employer side only. (Banco Industrial 2026)

Rule 4 -- ISR base (rentas del trabajo)

• ISR taxable income formula — annual_taxable = annual_ordinary_salary + annual_bono_incentivo (subject to ISR, NOT to IGSS) - IGSS_IVS_and_other_deductible_contributions - Q48,000 fixed personal deduction (no documentation) - life insurance (non-dotal, proportional share) - donations (state/universities unlimited; non-profits capped at 5% of gross) - IVA credit (documented personal purchases, capped at Q12,000/year) (Decreto 10-2012; SAT; vescco; inbers)

The first Q4,000/month is effectively exempt via the Q48,000 fixed deduction.

Rule 5 -- ISR progressive brackets

ISR progressive brackets (SAT; Decreto 10-2012)

Annual taxable income	Tax
Q0.01 -- Q300,000	5% of taxable income
Over Q300,000	Q15,000 + 7% of the excess over Q300,000

Cumulative check: at exactly Q300,000, bracket 1 tax = 5% × Q300,000 = Q15,000, which equals the fixed amount that opens bracket 2 — the schedule is continuous. Source: SAT; Decreto 10-2012.

Rule 6 -- IGSS registration threshold is 1 worker

• IGSS employer registration threshold — Every employer with 1 or more workers must register with IGSS and affiliate employees, since 17 January 2023. The old 3-worker threshold (Acuerdo 1123) no longer applies. (Acuerdo Junta Directiva 1529; Prensa Libre; IGSS patronos)

Rule 7 -- Minimum contribution base tied to minimum wage

• Minimum contribution base / no confirmed ceiling — IGSS applies a minimum contribution base ("cuota mínima") tied to the minimum wage. There is no confirmed standard ceiling for contributions from an authoritative source — contributions apply to full ordinary salary. [RESEARCH GAP — reviewer to confirm] the maximum insurable salary affecting the IVS pension benefit. (IGSS noticia, 2022)

Rule 8 -- Forms and deadlines

Forms and deadlines table (oficsa; vescco; SAT)

Form / event	Purpose	Frequency / deadline
SAT-1331 (RetenISR2 Web)	Employer monthly ISR withholding return	Monthly
SAT-1431	Employee's annual declaration of deductions to employer	Annual (Jan–Mar window)
Constancia de retención	Withholding certificate to employee	Within 10 business days of final/annual payment
Annual liquidation / refund	Year-end ISR reconciliation; over-withholding refund	By 28 February of following year
IVA-FEL planilla	Personal-purchase VAT credit filing	First business days of January (commonly cited 10 January)

Rule 9 -- 2026 reform (Decreto 13-2026)

• Decreto 13-2026 reform details — Approved by Congress 28 April 2026. Minimum-wage workers are exempt from ISR withholding from 2026 onward. The personal deduction is redefined as 12 monthly non-agricultural minimum salaries including the Q250 bono (replacing the flat Q48,000), auto-updating to the highest minimum wage. For 2026 only, an extraordinary additional deduction of Q3,024 (no documentation) applies; it takes effect 8 days after publication, with remaining provisions effective 1 January 2027. (Prensa Libre; vescco; Congreso; DCA)

Computed (not directly published — flag if used): 12 × (Q4,002.28 + Q250) = Q51,027.36 as the 2026 non-agri C1 derived personal-deduction figure. Treat as computed, not a published statutory number.

Rule 10 -- Minimum wage by circumscription (2026, non-agri)

Minimum wage by circumscription table (EY Centroamérica; Acuerdo Gubernativo 256-2025; Prensa Libre; AGN)

Circumscription	Daily	Monthly salary	+ Q250 bono = total
C1 (Dept. of Guatemala)	Q131.58	Q4,002.28	Q4,252.28
C2 (rest of country)	Q125.49	Q3,816.90	Q4,066.90

Agricultural and maquila/export rates differ — confirm by activity.

Section 6 -- Tier 2 catalogue

When payroll data is ambiguous or client circumstances are unclear, flag these for reviewer confirmation.

T2-1 -- Department-specific IGSS allocation

• Trigger/Issue/Action — Trigger: Employer needs the exact Accidentes/EMA/IVS split for a specific department. Issue: Only the headline totals (4.83% / 10.67% / 15.50%) are firmly confirmed. [RESEARCH GAP — reviewer to confirm] the per-department split. Action: Flag for reviewer; confirm against the current Junta Directiva acuerdo for that department.

T2-2 -- Minimum-wage worker under Decreto 13-2026

• Trigger/Issue/Action — Trigger: Worker earns minimum wage in 2026 onward. Issue: ISR exemption + formulaic personal deduction + extraordinary Q3,024 transitional deduction; effective dates depend on Diario Oficial publication. Action: Flag for reviewer; confirm wage and publication date before applying.

T2-3 -- IGSS arrears / mora

• Trigger/Issue/Action — Trigger: Employer has unpaid IGSS contributions. Issue: Mora uses the Junta Monetaria maximum simple rate; a formal aviso de cobro adds a 5% administrative surcharge capped at Q3,000. The former 50% surcharge-exemption benefit was repealed. Action: Do not quantify without an IGSS statement. Escalate to a licensed accountant.

T2-4 -- Maximum insurable salary / pension ceiling

• Trigger/Issue/Action — Trigger: Client asks about the IVS pension benefit ceiling. Issue: [RESEARCH GAP — reviewer to confirm] — the exact current Q amount was not confirmed from an authoritative source. Action: Do not state a figure. Escalate; confirm with IGSS.

T2-5 -- Non-standard wage components

• Trigger/Issue/Action — Trigger: Worker receives commissions, overtime, bonuses beyond the Q250 bono, or in-kind benefits. Issue: Some components form part of ordinary salary (IGSS base) and some do not; the Q250 bono incentivo is specifically excluded from IGSS but subject to ISR. Action: Flag for reviewer to confirm which components enter the IGSS base.

T2-6 -- Donations and IVA credit deductions

• Trigger/Issue/Action — Trigger: Worker claims donation deductions or the IVA-FEL credit. Issue: Donations to non-profits are capped at 5% of gross income; the IVA credit is capped at Q12,000/year and requires the planilla filed in early January. Action: Flag for reviewer; require documentation before applying.

Section 8 -- Bank statement reading guide

How IGSS and ISR debits appear on Guatemalan bank statements

Banco Industrial:

• Description: "IGSS", "IGSS PLANILLA", "INSTITUTO GUATEMALTECO DE SEGURIDAD SOCIAL"
• ISR: "SAT RETENISR", "SAT-1331"
• Timing: IGSS planilla paid monthly; ISR withholding remitted monthly

Banrural (Banco de Desarrollo Rural):

• Description: "IGSS CUOTA", "SEGURIDAD SOCIAL", "INTECAP", "IRTRA"
• Timing: Monthly

BAM (Banco Agromercantil) / G&T Continental / BAC:

• Description: "IGSS", "PLANILLA IGSS", "SAT ISR", "RETENCION ISR"
• Timing: Monthly

Key identification tips:

1. IGSS and ISR debits are always outgoing (DEBITO), never credits.
2. Employee IGSS should be ≈ 4.83% of ordinary salary; employer IGSS ≈ 10.67%; INTECAP + IRTRA ≈ 2%.
3. The Q250 "BONO" / "BONIFICACION INCENTIVO" is NOT subject to IGSS — exclude from the contribution base.
4. Do not confuse SAT/ISR debits (income tax) with IGSS debits (social security).
5. Inbound "IGSS SUBSIDIO" / "JUBILACION" / "PENSION" are benefits received, not contributions.
6. Irregular IGSS debits referencing "MORA" or "AVISO DE COBRO" include penalties — flag for reviewer.

Section 9 -- Onboarding fallback

If the client provides only a bank statement and no other information:

1. Scan for IGSS debits -- identify outgoing payments matching Section 3.1/3.2 patterns.
2. Reverse-engineer the ordinary salary: employer IGSS debit / 10.67% ≈ ordinary salary; employee IGSS / 4.83% ≈ ordinary salary. They should reconcile.
3. Identify ISR withholding -- match SAT/ISR debits (Section 3.3); these are income tax, not social security.
4. Separate the bono -- the Q250 bono incentivo is excluded from IGSS but subject to ISR.
5. Flag for reviewer: "IGSS/ISR classification derived from bank statement amounts only. Ordinary salary, circumscription, and deductions have not been independently verified. Reviewer must confirm before filing. Note Decreto 13-2026 minimum-wage exemption if applicable."

Spot-check (Q360,000): taxable Q360,000 − Q6,588 − Q48,000 = Q305,412.00; over Q300,000 by Q5,412.00; ISR = Q15,000 + 7% × Q5,412.00 = Q15,000 + Q378.84 = Q15,378.84. ✓ Source: Decreto 10-2012; SAT. (Worked Example 3 above deducts the full 4.83% IGSS rather than IVS-only; reviewer to confirm which contributions are deductible for the specific client — both treatments shown for transparency.)

Test suite

Test 1: Ordinary salary Q5,000/mo. Employee IGSS = 4.83% × 5,000 = Q241.50. ✓

Test 2: Ordinary salary Q5,000/mo. Employer IGSS = 10.67% × 5,000 = Q533.50; INTECAP+IRTRA = 2% × 5,000 = Q100.00; employer total = 12.67% × 5,000 = Q633.50. ✓

Test 3: Annual taxable income Q237,510 (from Q25,000/mo salary less 4.83% IGSS less Q48,000). ISR = 5% × Q237,510 = Q11,875.50; monthly ≈ Q989.63. ✓

Test 4: Annual taxable income exactly Q300,000. ISR = 5% × 300,000 = Q15,000.00 (bracket boundary). ✓

Test 5: Annual taxable income Q305,412. ISR = Q15,000 + 7% × Q5,412 = Q15,378.84. ✓

Test 6: Q250 bono incentivo paid. IGSS base contribution on the bono = Q0.00 (excluded). Bono IS subject to ISR. ✓

Test 7: Employer with 1 worker. IGSS registration required? YES (Acuerdo 1529, since 17 Jan 2023). ✓

Test 8: 2026 minimum-wage worker (Q4,002.28/mo). ISR withholding under Decreto 13-2026 = exempt (flag for reviewer to confirm publication/effective date). ✓

Test 9: Min-wage non-agri C1 monthly total = Q4,002.28 + Q250 bono = Q4,252.28. ✓

Test 10: Computed 2026 personal deduction (Decreto 13-2026, C1) = 12 × (Q4,002.28 + Q250) = Q51,027.36 (derived, flag as computed). ✓

Prohibitions

• NEVER apply IGSS to the Q250 bonificación incentivo — it is excluded from the contribution base.
• NEVER deduct INTECAP or IRTRA from the employee — they are employer-only (the cuota laboral is 4.83% flat).
• NEVER state a maximum insurable salary / IVS pension ceiling — that figure is a confirmed RESEARCH GAP.
• NEVER state a per-department IGSS split as fact — only the 4.83% / 10.67% / 15.50% totals are confirmed.
• NEVER use current-year minimum-wage ISR rules for prior years without confirming Decreto 13-2026 effective dates.
• NEVER quantify IGSS mora or arrears without an IGSS statement — escalate.
• NEVER confuse SAT/ISR debits (income tax) with IGSS debits (social security).
• NEVER present the Q51,027.36 Decreto 13-2026 figure as published — it is a derived computation, flag it as such.
• NEVER present IGSS/ISR figures as definitive — always label as estimated and direct the client to IGSS/SAT records.
• NEVER compute penalties without escalating to a licensed Guatemalan accountant.
