Angola's E-Invoicing Mandate: The Simplified-Regime and Group C Guide

If you sell goods or services in Angola and your business sits in the simplified VAT regime, your current invoicing routine expires in days. Starting September 21, 2026, every sale you make — to another business, to a walk-in customer, even to the government — must be issued through software certified by the Angolan tax authority (AGT), with the data transmitted to the tax administration in real time. Paper invoices, uncertified point-of-sale printouts, and pro-forma documents dressed up as invoices will no longer count, and each non-compliant sale carries its own penalty.

This is phase two of Angola's mandatory e-invoicing rollout under Presidential Decree 71/25. Large taxpayers and state suppliers have lived with it since January 1. Now it is every simplified-regime business's turn — regardless of size. Here is what the new rule demands, how it interacts with the simplified tax rates small businesses actually pay, and a practical checklist to get compliant before the deadline.

What Changes on September 21​

Presidential Decree 71/25, published March 20, 2025, approved Angola's Legal Framework for Invoices and replaced the previous invoicing regulation. The decree gave taxpayers a six-month grace period, then rolled out electronic invoicing in two phases:

• Phase one (January 1, 2026): mandatory e-invoicing for Large Taxpayers registered with the Large Taxpayers Tax Office (RFGC) and for suppliers to the State.
• Phase two (September 21, 2026): the obligation extends to all taxpayers under the General or Simplified VAT regimes, regardless of size.

From that date, virtually every company operating in Angola must issue electronic invoices for every sale of goods or provision of services — B2B, B2C, and B2G alike. The Ministry of Finance has since published Executive Decree 2683/25 with the technical specifications: the software data structure, the official electronic invoice model, and the procedural specs your invoicing system must follow.

An electronic invoice, as the regulation defines it, is a document issued and received through digital means, via AGT-authorized software, that meets the technical and legal standards — including real-time transmission of the invoice data to the AGT. Your software provider must be registered with and validated by the AGT; using a generic accounting app that nobody certified is the same as issuing no invoice at all.

Are You in the Simplified Regime?​

This is where Angolan small businesses most often get confused, because two different "simplified" concepts apply to you at once — one for VAT (which determines whether September 21 applies to you) and one for income tax (which determines the rate you pay). They have different thresholds, so work through them separately.

The VAT simplified regime: 25 million to 350 million kwanzas​

You fall under the Simplified VAT Regime if your annual turnover or import operations sit between 25 million KZ and 350 million KZ (roughly €25,000 to €349,000). If that is you, September 21 is your deadline, full stop: all operations must be invoiced electronically through AGT-certified software.

Businesses below the 25-million-kwanza line generally sit in the VAT Exemption regime. That regime gets lighter treatment — printed invoices approved by the AGT are still acceptable, and exemption-regime taxpayers and individuals may issue invoices directly through the AGT Portal, subject to a cap of 300 invoices per year. If you are growing toward the threshold, plan the jump to certified software now rather than mid-year.

The Group C income tax rate: 6.5% up to 10 million kwanzas​

Separately, Angola taxes the business income of small individual traders under Group C of the IRT (Imposto sobre os Rendimentos do Trabalho, the individual income tax). Under the 2026 Budget framework, Group C taxpayers whose annual turnover does not exceed 10 million KZ pay a flat 6.5% rate on their volume of sales of goods and services, with income up to 150,000 KZ exempt from the tax.

Note how the thresholds stack: a micro-trader under 10 million KZ pays the 6.5% Group C rate and typically sits in the VAT Exemption regime (portal invoicing up to 300 invoices a year). Cross 25 million KZ and you enter the VAT simplified regime — certified software and real-time reporting become mandatory on September 21. The 2026 Budget also requires electronic tax declarations for taxpayers under the general or simplified regimes, so the direction of travel is unmistakable: everything fiscal is going digital.

What a Compliant Invoice Looks Like​

Certified software does most of the heavy lifting, but you remain responsible for what goes into it. Under PD 71/25, every invoice must:

• Be written in Portuguese.
• Show the name, taxpayer number, and address of both seller and buyer.
• Carry a sequential number and year (invoice numbering is now tied to the AGT system, and each processed invoice is stamped with a unique digital code from the AGT).
• Describe the goods or services, including quantities, plus the time of supply.
• State unit prices and totals in kwanzas.
• Show applicable taxes — or, where no tax is due, cite the legal provision that exempts it.
• State the date and place of supply and the date of issue.
• Identify the certified software (or approved printing facility) used.

Timing matters too: the invoice must be issued no later than five business days after the underlying transaction. For ongoing sales or services, you may issue one "global" invoice covering up to one month.

Just as important is what does not count as an invoice: pro-forma invoices, bills of lading, credit and debit notes standing alone, purchase orders, payment notes, shipping notes, cash withdrawal notes, quotes, and budgets. If your current habit is handing a customer a quote and calling it a day, that habit becomes a violation on September 21. Corrections and cancellations go through credit notes that state the reason.

A few practical combinations exist to keep paperwork light. A receipt must be issued whenever an invoice is paid in full or in part — unless you issued an invoice-receipt, a payment note-receipt, a generic invoice, or a global invoice-receipt, in which case no separate receipt is needed. And if you re-bill expenses you originally incurred yourself and pass on economically, you must issue an invoice (with VAT); if you merely incurred the cost on a client's behalf and the invoice is addressed to them, a debit note suffices with no VAT.

Narrow exemptions​

Invoice issuance is excused only in a few cases where the buyer is an individual: sales through vending machines or electronic systems, ticketed sales (transport, events, tolls), and street or market vendors. In those cases a sales slip may substitute for the invoice. Everyone else issues a full invoice for every sale — including advance payments and including non-profit organizations.

The Reporting Behind the Invoice​

E-invoicing is the visible part; the decree also wires your back office directly to the AGT. Taxpayers must electronically communicate:

• The location of every office or facility where invoices are issued.
• The invoicing software used at each facility.
• The invoice series used — and not used.
• Annual inventory files closed December 31, submitted by February 15 of the following year.
• Annual SAF-T accounting files, submitted by April 10 of the following year.

Taxpayers under the General and Simplified VAT regimes must additionally transmit issued invoices, receipts, and other fiscal documents to the AGT through the SAF-T file. Invoices travel in JSON format via the AGT portal or a REST API, and the AGT-issued validation code is what makes the invoice — and the VAT on it — deductible.

One timing relief worth knowing: the AGT waived SAF-T accounting-file penalties for the 2025 financial year, acknowledging that many taxpayers could not update their systems in time, and made 2025 submission voluntary. That waiver ends with the year. SAF-T compliance for the 2026 financial year is mandatory, with penalties attached — so the system you stand up for September's invoicing deadline should be the same system that produces a clean SAF-T file next April.

Self-Billing: Useful, but Capped​

If you buy from individuals who cannot issue invoices, or from the primary sector (agriculture, forestry, fishing, livestock, apiculture, handicrafts), the decree lets you issue the invoice yourself — but only if you maintain organized accounting. These self-billed ("Auto-Facturação") invoices must carry that explicit mention plus the supplier's identification data, and must be reported electronically to the AGT.

Two hard limits apply: self-billing must not exceed 20% of your total costs (extendable to 40% only where the acquired goods are essential to your main activity), and you must withhold tax at source on these transactions. If farm-gate or informal-sector purchases are a big share of your cost base, model the 20% cap now — breaching it turns deductible costs into a compliance problem.

Penalties: Per Invoice, and They Stack​

Non-compliance is priced per invoice, which is what makes it dangerous for high-volume small businesses:

• Selling without an invoice: 7% of the invoice value — 15% for repeat behavior.
• Invoice missing required details: 5% or 1% of the invoice value, depending on which detail is missing.
• Invoice issued late (past the five-business-day window): 0.2% of the invoice value.
• No receipt issued: 1% of the invoice value.
• Failure to safeguard documents: 1% of the invoice value.
• SAF-T not submitted, or submitted with errors: same penalty as selling without an invoice (7%, or 15% repeated) — and submitting a SAF-T file that omits invoices counts as non-issuance.

One mercy rule: for a first breach, the penalty is reduced by 50%. Do not plan around it — plan to never need it.

The AGT pairs the stick with a carrot: the "Lottery Invoice" (Factura da Sorte) program will run regular lotteries awarding prizes to randomly drawn invoices, giving your customers a reason to demand a proper invoice for every purchase. Expect buyers to start asking for invoices they never bothered with before — which is precisely the point.

Your Pre-September 21 Checklist​

Six days is tight but workable for a small business. Work through these in order:

1. Confirm your regime. Pull your last twelve months of turnover (plus import volumes). Between 25 million and 350 million KZ means the full mandate applies to you on September 21. Below 25 million, confirm your exemption-regime status and whether the 300-invoice portal cap covers your volume.
2. Get AGT-certified software — or register for the portal. If you already use invoicing software, ask your vendor for written proof of AGT certification and real-time transmission capability under Executive Decree 2683/25. If they cannot produce it, switch now. Micro-businesses staying in the exemption regime should register on the AGT Portal and test-issue an invoice before the deadline.
3. Register your invoicing footprint. Report to the AGT every location where you issue invoices, the software used at each, and your invoice series. New series must be traceable in the system.
4. Rebuild your invoice template. Portuguese language, sequential numbering, kwanza totals, tax-or-exemption citation, time of supply, software identification. Purge pro-forma and quote-as-invoice habits from every till and sales desk.
5. Set the five-day rule in stone. Whoever closes a sale owns the invoice within five business days. For retainer and subscription-style services, switch to monthly global invoices.
6. Fix self-billing now. If you buy from individuals or primary-sector suppliers, start issuing Auto-Facturação documents, apply withholding at source, and check your ratio against the 20% cost cap.
7. Reconcile invoice series monthly. Because an incomplete SAF-T file draws the same penalty as issuing no invoices at all, reconcile every series — issued, cancelled, credit-noted — to your sales ledger each month, not next April.
8. Train customer-facing staff. With the invoice lottery coming, customers will demand invoices. Make sure every cashier and field seller can issue one on the spot.
9. Check your Group C position. If your turnover is at or under 10 million KZ, confirm you are correctly classified for the 6.5% rate and the 150,000 KZ exemption — and remember that crossing the VAT simplified threshold changes your invoicing obligations even though your income tax lane stays the same.
10. Watch the new IRT code. The government has approved a draft bill for a brand-new individual income tax code — replacing the current schedular system with an integrated one, cutting twelve brackets to six, and exempting micro and small businesses in defined cases. It is not law yet, but it could reshape the Group C landscape you just mapped.

Keep Your Books Audit-Ready, Not Just Invoice-Ready​

September 21 forces the invoice; April 10 judges the books behind it. The businesses that will sail through Angola's new regime are the ones treating e-invoicing as the front end of clean, reconcilable records — every invoice series tied to the sales ledger, every cost backed by a valid document, every SAF-T export reproducible from the same data. If your records live across a till roll, a spreadsheet, and somebody's memory, the mandate will find the gaps before your accountant does.
