Section 2 -- Required inputs and refusal catalogue

Required inputs

• Minimum viable inputs — Minimum viable -- the tax year (2025 or 2026) and the employee's monthly GROSS salary in RSD. Without the tax year, STOP: the non-taxable amount, the floor base and the ceiling base all differ between 2025 and 2026.

Recommended -- whether the employee is a Serbian tax resident, the number of working hours in the month (for minimum-wage adequacy checks), and whether any new-hire / start-up employment relief is claimed.

Ideal -- the employer's PPP-PD filings for the period, the employee's annual net income (for the supplementary PP GPDG), age as at 31 December (under-40 deduction), number of dependent family members, and bank statements showing remittances to Poreska uprava / PIO / RFZO / NSZ.

Refusal catalogue

• R-RS-SSC-1 -- Tax year not specified — Trigger: the period (2025 vs 2026) is not provided.

Section 3 -- Payment pattern library

This is the deterministic pre-classifier for Serbian bank statement transactions related to payroll tax and social security. 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 (payee, primalac, or payment description) as it appears in the bank statement. Serbian payroll tax and contribution remittances are statutory obligations — EXCLUDE them from any VAT return; they are not business supplies. Employer contributions are a deductible payroll cost; employee contributions and salary tax are amounts withheld from gross pay (not an additional employer cost).

Section 4 -- Worked examples

Six payroll classifications and computations for a hypothetical Serbian employer. Unless stated, 2026 parameters are used (non-taxable RSD 34,221; min base RSD 51,297; max base RSD 732,820) per KPMG Dec 2025 alert and Orbitax. All arithmetic recomputed end-to-end.

Example 1 -- Standard mid-range salary (2026)

Input line: 25.01.2026 ; ISPLATA ZARADE — JANUAR ; DEBIT ; ZARADA M. PETROVIC ; -108,572.10 ; RSD

Scenario: Gross monthly salary RSD 150,000 (2026), resident employee, between floor and ceiling.

Reasoning (net pay derivation):

• Salary tax base = 150,000 − 34,221 (non-taxable) = 115,779. Salary tax = 10% x 115,779 = 11,577.90.
• Employee contributions: base = 150,000 (within floor/ceiling). 19.90% x 150,000 = 29,850.00.
• Net pay = 150,000 − 11,577.90 − 29,850.00 = 108,572.10 (matches the statement line).
• Employer contributions (paid on top): 15.15% x 150,000 = 22,725.00.
• Total employer cost = 150,000 + 22,725.00 = 172,725.00.

Classification: Net salary line EXCLUDE from VAT — payroll. Reconcile to the PPP-PD: salary tax RSD 11,577.90 + employee contributions RSD 29,850.00 + employer contributions RSD 22,725.00.

Example 2 -- Salary below the minimum contribution base (2026)

Input line: 25.02.2026 ; ISPLATA ZARADE — FEBRUAR ; DEBIT ; ZARADA J. JOVANOVIC ; -29,214.00 ; RSD

Scenario: Part-time arrangement, gross RSD 40,000 (2026), below the floor base RSD 51,297.

Reasoning:

• Salary tax base = 40,000 − 34,221 = 5,779. Salary tax = 10% x 5,779 = 577.90.
• Contribution base = max(40,000, 51,297) = 51,297 (floor applies). Employee contributions = 19.90% x 51,297 = 10,208.10.
• Net pay = 40,000 − 577.90 − 10,208.10 = 29,214.00 (matches).
• Employer contributions = 15.15% x 51,297 = 7,771.50.
• Total employer cost = 40,000 + 7,771.50 = 47,771.50.

Classification: EXCLUDE from VAT — payroll. Note: contributions are computed on the RSD 51,297 floor even though gross pay is lower (Eurofast / Orbitax). Reviewer should also confirm minimum-wage adequacy (Section 8).

Example 3 -- High salary above the maximum contribution base (2026)

Input line: 25.03.2026 ; ISPLATA ZARADE — MART ; DEBIT ; ZARADA D. NIKOLIC ; -667,590.92 ; RSD

Scenario: Senior role, gross RSD 900,000 (2026), above the ceiling base RSD 732,820.

Reasoning:

• Salary tax has NO contribution-base cap: base = 900,000 − 34,221 = 865,779. Salary tax = 10% x 865,779 = 86,577.90.
• Contribution base = min(900,000, 732,820) = 732,820 (ceiling applies). Employee contributions = 19.90% x 732,820 = 145,831.18.
• Net pay = 900,000 − 86,577.90 − 145,831.18 = 667,590.92 (matches).
• Employer contributions = 15.15% x 732,820 = 111,022.23.
• Total employer cost = 900,000 + 111,022.23 = 1,011,022.23.

Classification: EXCLUDE from VAT — payroll. The salary tax is on full gross-less-non-taxable; only contributions are capped at the ceiling base (Orbitax).

Example 4 -- Consolidated remittance to the Tax Administration (PPP-PD)

Input line: 05.02.2026 ; PORESKA UPRAVA ; DEBIT ; PPP-PD POREZ I DOPRINOSI 01/2026 ; -64,152.90 ; RSD

Scenario: The employer's consolidated PPP-PD remittance for the Example 1 employee (salary tax + all contributions).

Reasoning:

• Salary tax = 11,577.90 + employee contributions 29,850.00 + employer contributions 22,725.00 = 64,152.90 (matches).
• This is the single consolidated PPP-PD payment that funds PIO, RFZO and NSZ plus the 10% salary tax.

Classification: EXCLUDE from VAT. Matches "PORESKA UPRAVA" / "PPP-PD" (patterns 3.1). Statutory remittance; the employer-contribution portion (RSD 22,725.00) is a deductible payroll cost.

Example 5 -- VAT payment misread as a contribution (do NOT confuse)

Input line: 15.02.2026 ; PORESKA UPRAVA ; DEBIT ; PDV 01/2026 ; -240,000.00 ; RSD

Reasoning:

• Counterparty is "PORESKA UPRAVA" but the reference says "PDV" (VAT, pattern 3.4). This is a Value Added Tax remittance (standard 20%), NOT a payroll social contribution. Do not include it in payroll/contribution totals.

Classification: EXCLUDE from any contribution classification — this is VAT. Handle under the Serbia VAT skill, not this skill.

Example 6 -- Annual supplementary PIT (PP GPDG), 2025 income

Scenario: A Serbian resident has net annual income of RSD 20,000,000 for 2025 (over the RSD 5,439,096 threshold), no dependents, aged over 40 at 31 Dec 2025. Compute the annual (supplementary) PIT due with PP GPDG (filed by 15 May 2026). 2025 thresholds apply.

Reasoning (KPMG Feb 2026 alert):

• Income above the non-taxable threshold = 20,000,000 − 5,439,096 = 14,560,904.
• Standard personal deduction = RSD 725,213. Deduction cap = 50% x 14,560,904 = 7,280,452; the RSD 725,213 deduction is below the cap, so allowed in full.
• Taxable base = 14,560,904 − 725,213 = 13,835,691.
• Band 1 (10% up to RSD 10,878,192): 10% x 10,878,192 = 1,087,819.20.
• Band 2 (15% above RSD 10,878,192): 15% x (13,835,691 − 10,878,192) = 15% x 2,957,499 = 443,624.85.
• Annual PIT due = 1,087,819.20 + 443,624.85 = 1,531,444.05.

Classification: Personal obligation of the individual, EXCLUDE from VAT and from employer payroll. File PP GPDG online by 15 May 2026. Note: this supplementary PIT is separate from and on top of the monthly 10% salary tax already withheld; it is not a contribution. Reviewer to confirm the exact ordering of deductions vs the 10%/15% bracket break [RESEARCH GAP — reviewer to confirm].

Section 5 -- Tier 1 rules

These rules apply when the data is clear and all required inputs are available. Apply exactly as written. All figures cite their source; figures without a confirmed source carry a [RESEARCH GAP] marker.

Rule 1 -- Salary tax formula (flat 10%)

• Salary tax formula — salary_tax = 10% x (gross_salary - non_taxable_monthly_amount) (Eurofast / KPMG)
• Non-taxable amount / cap note — Non-taxable amount: RSD 28,423 (2025) / RSD 34,221 (2026) — Eurofast / KPMG. The salary tax base is NOT capped by the contribution ceiling. If gross < non-taxable amount, salary tax is zero (never negative). (Eurofast / KPMG)

Rule 2 -- Employee contributions = 19.90% of the contribution base

• Employee contributions formula — employee_contributions = 19.90% x contribution_base = 14% PIO + 5.15% RFZO + 0.75% NSZ (PwC)
• Withholding note — Withheld by the employer from gross pay — PwC. (PwC)

Rule 3 -- Employer contributions = 15.15% of the contribution base

• Employer contributions formula — employer_contributions = 15.15% x contribution_base = 10% PIO + 5.15% RFZO + 0% NSZ (no employer unemployment) (PwC)
• Paid on top note — Paid on top of the employee's gross salary — PwC. (PwC)

Rule 4 -- Contribution base floor and ceiling

• Contribution base clamp formula — contribution_base = clamp(gross_salary, min_base, max_base) (Eurofast / Orbitax)
• Min base — RSD 45,950 (2025) / RSD 51,297 (2026). Contributions are due on at least the minimum even if actual pay is lower. (Eurofast / Orbitax)
• Max base — RSD 656,425/mo (2025) / RSD 732,820/mo (2026); annual max RSD 8,793,840 (2026). No contributions accrue above the cap. (Eurofast / Orbitax)
• Applicability of floor/ceiling — Floor/ceiling apply to BOTH employee and employer contributions. They do NOT apply to the 10% salary tax base.

Rule 5 -- Net pay derivation

• Net pay and employer cost formula — net_pay = gross_salary - salary_tax - employee_contributions total_employer_cost = gross_salary + employer_contributions

Rule 6 -- Combined social burden = 35.05%

• Combined social burden — 19.90% (employee) + 15.15% (employer) = 35.05% of gross, subject to the floor/ceiling base. (PwC / Eurofast)

Rule 7 -- Monthly reporting via PPP-PD

• Monthly reporting — The 10% salary tax and all contributions are reported and paid via the consolidated electronic PPP-PD return at each salary payment (with the salary, not on a fixed monthly day). (Tax Administration / KPMG)

Rule 8 -- Annual (supplementary) PIT for residents — PP GPDG

• Filing threshold and deadline — Residents with net 2025 income above RSD 5,439,096 (3x average annual salary) must file PP GPDG by 15 May 2026. (KPMG)
• Annual PIT rates — 10% on net income above the threshold up to RSD 10,878,192; 15% above that. (KPMG / PwC)
• Standard and dependent deductions — Standard personal deduction RSD 725,213 (40% of average annual salary); RSD 271,955 per dependent (15%); combined deductions capped at 50% of net income. (KPMG)
• Under-40 additional deduction — Taxpayers under 40 on 31 Dec 2025 get an additional deduction of RSD 5,439,096 on employment/self-employment income. (KPMG)

Rule 9 -- Non-taxable amount is indexed annually

• Indexation — The monthly non-taxable salary amount is indexed annually; the next change is scheduled for 1 January 2027. Do not roll a prior year's figure forward without confirming the published value. (KPMG Dec 2025 alert)

Rule 10 -- Minimum wage adequacy

• Minimum wage rates — Net minimum wage is set per working hour: RSD 308/hr (Jan–Sep 2025), RSD 337/hr (Oct–Dec 2025, Official Gazette RS 67/2025), RSD 371/hr (from 1 Jan 2026, Official Gazette RS 78/2025). Monthly minimum = hourly rate x working hours in the month (160–184 hrs). Confirm the employee's net pay is not below the applicable minimum. (Zunic Law / RS Partners)

Section 6 -- Tier 2 catalogue (reviewer judgement)

When data is ambiguous or circumstances are unclear, flag these for reviewer confirmation. Do not resolve them autonomously.

T2-1 -- Tax-year boundary (December/January payroll)

• Trigger / Issue / Action — Trigger: salary paid in early January for December work, or vice versa. Issue: The non-taxable amount and contribution bases switch on 1 January. Whether the 2025 or 2026 parameters apply depends on the date of payment, not the period worked. Misapplying the year changes the salary tax and the floor/ceiling. Action: Flag for reviewer; confirm the payment date and which parameter set applies.

T2-2 -- New-hire / start-up employment relief

• Trigger / Issue / Action — Trigger: employer claims reduced contributions/tax for newly hired employees. Issue: Relief is extended through 31 December 2026 (KPMG), but eligibility conditions and exact relief amounts are not detailed here [RESEARCH GAP — reviewer to confirm]. Action: Do NOT apply relief; flag for reviewer.

T2-3 -- Residency for the annual PIT

• Trigger / Issue / Action — Trigger: individual has foreign income or split-year residency. Issue: Only Serbian residents are taxed on worldwide income via PP GPDG. Residency status drives whether and on what base the annual PIT applies. Action: Flag for reviewer; confirm residency and worldwide-income scope.

T2-4 -- Deduction-ordering for the annual PIT

• Trigger / Issue / Action — Trigger: computing PP GPDG where personal/dependent deductions and the 10%/15% bracket interact. Issue: The exact ordering of deductions versus the RSD 10,878,192 bracket break, and whether the 50%-of-net-income cap is measured on gross net income or income-above-threshold, is not fully pinned [RESEARCH GAP — reviewer to confirm]. Action: Flag for reviewer before finalising the annual PIT figure.

T2-5 -- Entrepreneurs and 'other income'

• Trigger / Issue / Action — Trigger: self-employed entrepreneur (lump-sum / paušalac) or 'other income' (royalties, service contracts). Issue: Contribution bases are type-specific and not detailed here [RESEARCH GAP — reviewer to confirm]. Action: Flag for reviewer; this skill covers employment income only.

T2-6 -- Penalties and default interest

• Trigger / Issue / Action — Trigger: overdue tax or contributions. Issue: Default interest accrues daily (NBS reference rate + 10 p.p.) plus misdemeanour fines under ZPPPA; exact RSD fine ranges are not pinned here [RESEARCH GAP — reviewer to confirm]. Action: Do not estimate; escalate to a licensed advisor.

Section 8 -- Bank statement reading guide (Serbian)

How payroll tax and contribution remittances appear on Serbian bank statements

Common Serbian banks: Banca Intesa, Komercijalna banka (NLB Komercijalna), OTP banka, Raiffeisen banka, UniCredit Bank Srbija, AIK Banka.

Tax Administration / consolidated:

• Payee (primalac): "PORESKA UPRAVA" or "PORESKA UPRAVA RS" / "PURS"
• Reference: "PPP-PD", "POREZ NA ZARADE", "POREZ I DOPRINOSI", with a period (e.g. "01/2026")
• Amount: salary tax + employee 19.90% + employer 15.15% for the period

Fund-specific (where remitted separately):

• "FOND PIO" / "PIO" -- pension & disability
• "RFZO" / "ZDRAVSTVENO" -- health
• "NSZ" -- unemployment

Key Serbian payroll terms:

• Zarada / plata = salary / wage
• Bruto = gross; neto = net
• Porez na zarade = tax on salaries (the 10%)
• Doprinosi = contributions
• Neoporezivi iznos = non-taxable amount
• Najniža osnovica = minimum (lowest) base; najviša osnovica = maximum (highest) base
• Minimalna zarada = minimum wage

Key identification tips:

1. Payroll-tax/contribution remittances are outgoing (DEBIT) to "PORESKA UPRAVA" or a named fund.
2. The 10% salary tax is on gross minus the non-taxable amount; contributions are on the clamped base — the two bases differ for low and high earners.
3. Do not confuse "PDV" (VAT), "POREZ NA DOBIT" (corporate tax), or "POREZ PO ODBITKU" (non-resident WHT) with payroll social contributions — all may show "PORESKA UPRAVA" as payee.
4. Net salary lines ("ISPLATA ZARADE" to the employee) are payroll, not contributions.
5. Match the consolidated remittance to the PPP-PD: it should equal salary tax + 19.90% + 15.15% for the period.

Section 9 -- Onboarding fallback

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

1. Scan for remittances -- identify outgoing payments matching Section 3 patterns ("PORESKA UPRAVA", "PPP-PD", "PIO", "RFZO", "NSZ", "DOPRINOSI").
2. Identify the consolidated PPP-PD line -- this funds salary tax + all contributions for the period.
3. Reverse-engineer approximate gross (employment income, within floor/ceiling): if total remittance R = salary tax + 19.90%G + 15.15%G and salary tax = 10%(G − non_taxable), then for a salary between the floor and ceiling base, R = 0.10(G − N) + 0.3505G = 0.4505G − 0.10N, so G ≈ (R + 0.10N) / 0.4505 (N = non-taxable amount for the year). Treat as an estimate only.
4. Confirm the tax year from the period reference (e.g. "01/2026" -> 2026 parameters).
5. Flag for reviewer: "Payroll figures derived from bank statement amounts only. Tax year, residency, contribution-base position (floor/ceiling), and any new-hire relief have not been independently verified. Reviewer must confirm before relying on these figures."

Test suite

All figures recomputed end-to-end. Unless stated, 2026 parameters (non-taxable RSD 34,221; floor RSD 51,297; ceiling RSD 732,820).

Test 1 (mid-range, 2026): Gross RSD 150,000. Salary tax = 10% x (150,000 − 34,221) = 11,577.90. Employee contr = 19.90% x 150,000 = 29,850.00. Net pay = 108,572.10. Employer contr = 15.15% x 150,000 = 22,725.00. Employer cost = 172,725.00.

Test 2 (below floor, 2026): Gross RSD 40,000. Salary tax = 10% x (40,000 − 34,221) = 577.90. Contribution base = 51,297 (floor). Employee contr = 19.90% x 51,297 = 10,208.10. Net pay = 29,214.00. Employer contr = 15.15% x 51,297 = 7,771.50.

Test 3 (above ceiling, 2026): Gross RSD 900,000. Salary tax = 10% x (900,000 − 34,221) = 86,577.90. Contribution base = 732,820 (ceiling). Employee contr = 19.90% x 732,820 = 145,831.18. Net pay = 667,590.92. Employer contr = 15.15% x 732,820 = 111,022.23.

Test 4 (consolidated PPP-PD, Test 1): Remittance = 11,577.90 + 29,850.00 + 22,725.00 = 64,152.90.

Test 5 (2025 parameters, mid-range): Gross RSD 150,000. Salary tax = 10% x (150,000 − 28,423) = 12,157.70. Employee contr = 19.90% x 150,000 = 29,850.00. Net pay = 150,000 − 12,157.70 − 29,850.00 = 107,992.30. Employer contr = 15.15% x 150,000 = 22,725.00.

Test 6 (gross below non-taxable amount, 2026): Gross RSD 30,000. Salary tax base = 30,000 − 34,221 = negative -> salary tax = 0 (never negative). Contribution base = 51,297 (floor). Employee contr = 19.90% x 51,297 = 10,208.10. Net pay = 30,000 − 0 − 10,208.10 = 19,791.90. (Reviewer must also check this against the applicable minimum wage.)

Test 7 (annual PIT, 2025 income, RSD 20,000,000, no dependents, over 40): Above threshold = 14,560,904. Less standard deduction 725,213 (below the 50% cap of 7,280,452) -> base 13,835,691. 10% x 10,878,192 = 1,087,819.20; 15% x 2,957,499 = 443,624.85; total = 1,531,444.05.

Test 8 (annual PIT below threshold): Resident net 2025 income RSD 5,000,000 < RSD 5,439,096 threshold -> no PP GPDG filing obligation; annual supplementary PIT = 0.

Prohibitions

• NEVER compute Serbian payroll without confirming the tax year (2025 vs 2026) — the non-taxable amount and bases differ.
• NEVER apply the contribution floor/ceiling to the 10% salary tax base — the salary tax has no base cap.
• NEVER compute contributions below the minimum base for a salary under the floor — the floor still applies.
• NEVER accrue contributions on the portion of salary above the maximum base.
• NEVER conflate the monthly 10% salary tax with the annual supplementary PIT (PP GPDG) — they are separate.
• NEVER add an employer unemployment (NSZ) contribution — there is none (employer is PIO + RFZO only).
• NEVER roll forward a prior year's non-taxable amount or base without confirming the published value (indexed annually; next change 1 Jan 2027).
• NEVER apply new-hire / start-up employment relief without reviewer confirmation.
• NEVER estimate penalties or default interest — escalate to a licensed advisor.
• NEVER treat "PDV", "POREZ NA DOBIT", or "POREZ PO ODBITKU" remittances as payroll social contributions.
• NEVER present figures marked [RESEARCH GAP] as confirmed — these require a licensed Serbian advisor.
• NEVER present Serbian payroll figures as definitive — label as estimated pending professional review.
