Section 4 -- Worked Examples

Example 1 -- ISS Computation (Outside Simples)

Input: Consulting firm in Sao Paulo. Monthly service revenue R$ 50,000. ISS rate 5%.

Computation:

• ISS = R$ 50,000 x 5% = R$ 2,500

Example 2 -- ICMS Computation (Outside Simples, Intrastate SP)

Input: Retailer in SP selling goods worth R$ 100,000. Internal rate 18%. Purchases R$ 60,000 with 18% ICMS.

Computation:

• ICMS on sales: R$ 100,000 x 18% = R$ 18,000
• ICMS credits on purchases: R$ 60,000 x 18% = R$ 10,800
• ICMS payable: R$ 18,000 - R$ 10,800 = R$ 7,200

Example 3 -- Interstate Sale (SP to BA)

Input: SP company sells R$ 10,000 goods to BA company. Interstate rate 7%. BA internal rate 19%.

Computation:

• ICMS charged: R$ 10,000 x 7% = R$ 700 (seller pays to SP SEFAZ)
• If B2B (buyer is taxpayer): buyer pays DIFAL of 12% (19% - 7%) to BA
• If B2C: seller collects DIFAL of 12% and remits to BA

Example 4 -- ISS Retention at Source

Input: Consulting invoice R$ 20,000 to large corporate client. ISS rate 5%. Subject to retention.

Computation:

• ISS = R$ 20,000 x 5% = R$ 1,000
• Client retains R$ 1,000 and remits to municipality
• Provider receives R$ 19,000
• Provider does not pay ISS separately on this invoice

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

5.1 ISS Structure

• ISS Structure — Municipal tax on services. Rate range 2% to 5%. Base: gross price of the service. General rule: taxed where the service provider is established. Exceptions under Art. 3 for services taxed where performed. (LC 116/2003)

5.2 ICMS Structure

• ICMS Structure — State tax on sale of goods, interstate/inter-municipal transport, telecommunications. Non-cumulative (credit for ICMS paid on inputs outside Simples). Rate varies by state and product. (LC 87/1996)

5.3 IPI Structure

• IPI Structure — Federal tax on industrialized products. Applies to manufacturers and importers. Rate varies by product per TIPI table (NCM code). Non-cumulative. Most self-employed service providers do NOT pay IPI. (Decreto 7.212/2010)

5.4 Simples Nacional Interaction

• Simples Nacional ICMS/ISS sublimit — R$ 3,600,000 BRL (ICMS and ISS included in DAS below this sublimit; above it, paid outside Simples at normal rates) (LC 123/2006, Art. 13, 18)

5.5 Nota Fiscal Types

• Nota Fiscal Types — NF-e (goods/ICMS), NFS-e (services/ISS), NFC-e (retail consumer), CT-e (transport). NFS-e issued via municipal portal with provider CNPJ, client CNPJ/CPF, service code, value, ISS rate, ISS amount.

Section 6 -- Tier 2 Catalogue (Reviewer Judgement Required)

6.1 ISS Location of Taxation

• ISS Location of Taxation — Flag for reviewer when services are performed in a municipality different from the provider's registration. Certain services are taxed where performed under LC 116/2003, Art. 3. (LC 116/2003, Art. 3)

6.2 DIFAL Computation

• DIFAL Computation — DIFAL applies when selling to a non-taxpayer consumer in another state. DIFAL = internal rate of destination state minus interstate rate. Flag for reviewer on all DIFAL calculations.

6.3 ICMS-ST (Substituicao Tributaria)

• ICMS-ST — ICMS collected upfront by manufacturer/importer for the entire chain. Applies to specific product categories. Computation requires MVA (Margem de Valor Agregado). Always flag for reviewer.

6.4 Software Classification

• Software Classification — SaaS/cloud services are generally ISS. Packaged software was historically ICMS but increasingly ISS. Flag for reviewer -- must check state and municipal legislation.

Tax Reform (IBS/CBS) -- Status

Brazil is replacing ICMS, ISS, IPI, PIS, and COFINS with IBS (state/municipal) and CBS (federal). Transition period 2026-2032; full implementation by 2033. Combined rate expected ~26.5%. Implementation laws being debated/enacted through 2025-2026. ESCALATE all tax reform transition questions.

PROHIBITIONS

• NEVER apply ICMS to pure services -- services are subject to ISS (except telecom and interstate transport)
• NEVER apply ISS to sale of physical goods -- goods are subject to ICMS
• NEVER ignore the R$ 3,600,000 sublimit for Simples Nacional ICMS/ISS
• NEVER assume ICMS rates are uniform across states -- they vary from 7% to 25%+
• NEVER assume ISS rates are the same in all municipalities -- they range from 2% to 5%
• NEVER compute IPI for pure service providers -- IPI applies only to industrialized products
• NEVER ignore ICMS-ST obligations -- they apply even to Simples Nacional companies
• NEVER advise on the IBS/CBS tax reform as if it is fully enacted
• NEVER present calculations as definitive -- always label as estimated and direct client to a CRC-registered contador
