Tax compliance is the unglamorous half of running an SME. Get it right and you stay invisible to your tax authority; get it wrong and you spend three months re-doing books and paying penalties.
This is a quick reference for the 6 SADC countries Letts Commerce serves. Not legal or accounting advice — work with a local accountant for filing — but the operational essentials in one place.
At-a-glance
| Country | VAT rate | Tax authority | E-invoicing | Filing cadence | |---|---|---|---|---| | 🇲🇼 Malawi | 16.5% | MRA | Required (MRA-eFiling) | Monthly | | 🇿🇲 Zambia | 16% | ZRA | Required (Smart Invoicing) | Monthly | | 🇹🇿 Tanzania | 18% | TRA | Required (EFD) | Monthly | | 🇲🇿 Mozambique | 16% | AT | Required (e-FIS) | Monthly | | 🇿🇼 Zimbabwe | 15% | ZIMRA | Required (FDMS) | Monthly | | 🇿🇦 South Africa | 15% | SARS | Required (eFiling) | Bi-monthly (most SMEs) |
E-invoicing is now universal across SADC. If your platform doesn’t generate compliant electronic tax invoices natively, you’re manually doing work the system should do for you.
Country-specific gotchas
🇲🇼 Malawi — Letts home
- VAT 16.5% on most taxable supplies. Some items zero-rated (basic foodstuffs); some exempt (financial services).
- Withholding tax — 3% on services, 10% on rentals, varies on imports. Often the more time-consuming of the two for SMEs.
- Tourism levy — 1% additional on hospitality + tour operators
- Fringe Benefits Tax — applies to non-cash benefits to employees
- Filing — monthly via MRA eFiling. Strict 20th-of-month deadline for VAT.
- Letts platform handling — VAT invoicing native; FBT and tourism levy configurable per business type.
🇿🇲 Zambia
- VAT 16% standard. Smart Invoicing system required for all VAT-registered businesses since 2024.
- Mineral Royalty Tax — relevant for mining + minerals merchants (graduated rate 5-10%)
- Withholding tax — 15% on services, 5% on rentals
- Filing — monthly. Smart Invoicing must transmit each invoice to ZRA in real-time.
- Letts platform handling — Smart Invoicing integration on roadmap for GA. Manual export to ZRA available today.
🇹🇿 Tanzania
- VAT 18% standard. Tanzania’s Electronic Fiscal Device (EFD) requirement is one of SADC’s strictest — every transaction must hit the EFD device + transmit to TRA.
- Skills and Development Levy (SDL) — 4.5% on payroll
- City Service Levy — varies by municipality
- Withholding tax — 5% on services to residents, 15% to non-residents
- Filing — monthly. Annual reconciliation due 90 days after year-end.
- Letts platform handling — EFD integration on roadmap. Until GA, hybrid mode (Letts books + dedicated EFD device).
🇲🇿 Mozambique
- VAT (IVA) 16% standard. Required AT-compliant electronic invoices via the e-FIS system.
- Imposto sobre o Rendimento de Pessoas Colectivas (IRPC) — 32% standard corporate income tax
- Withholding tax — 10-20% varies by service category
- Customs duties — apply to imports outside SADC; SADC FTA mostly clears for SADC-origin goods
- Filing — monthly VAT, quarterly IRPC pre-payments, annual IRPC return
- Letts platform handling — e-FIS integration on roadmap; Portuguese-language interface support coming with Mozambique GA.
🇿🇼 Zimbabwe
- VAT 15% standard. Multi-currency invoicing required (ZWG / USD / ZAR all valid for tax purposes).
- AIDS levy — 3% on top of corporate income tax
- Intermediated Money Transfer Tax (IMTT) — applies to most digital transactions, 4% (subject to change)
- Withholding tax — 10% on local services, 15% on imported services

🇿🇦 South Africa
- VAT 15% standard. SARS-compliant tax invoices required for any supply ≥R5,000 (or ≥R50 for retail).
- Provisional Tax — quarterly pre-payments toward annual income tax. SMEs commonly forget this; SARS reminds them with penalties.
- Skills Development Levy — 1% on payroll over R500k annual
- Filing — bi-monthly VAT for most SMEs (monthly if turnover >R30m). Provisional tax twice yearly.
- Letts platform handling — SARS-compliant tax invoicing native. CIPC integration for company data on roadmap.
The three universal pitfalls
Across every SADC country we work in:
1. Filing late
Most SADC tax authorities apply automatic penalties for late filing — typically 1-2% of tax due per month, capped. Set a calendar reminder for the 15th of every month and treat it like rent.
2. Mixing personal and business expenses
The single biggest source of additional tax assessments in SME audits. Use a dedicated business bank account + business mobile-money wallet. The platform tracks taxable vs non-taxable; the human still has to keep the money streams separate.
3. Misclassifying contractors as employees (or vice versa)
Most SADC tax authorities now apply economic-substance tests rather than contractual labels. If a contractor works exclusively for you, sets hours you dictate, and uses your equipment, they’re probably an employee for tax purposes — and you owe PAYE / SDL / etc.
