Tunisian services companies—consulting, IT, agencies, and professional firms—must keep VAT lines aligned with TTN clearance and monthly accountant declarations. From 2026, many joined the El Fatoora obligation goods exporters already knew. The operational question is how rates, exemptions, TEIF fields, and cabinet handoffs stay consistent as volume grows.
This FAQ-style guide covers what operators ask about VAT invoicing for services in Tunisia: common rates, exemption context, TTN fields that break clearance, and accountant coordination. It is not tax or legal advice—confirm binding treatment with your expert-comptable or DGI advisor before changing declarations.
VAT rates services PMEs see most often
Most billable services are taxed at the standard 19% VAT rate (taux normal): consulting days, software retainers, marketing fees, and maintenance contracts when no reduced regime applies. Lines must show HT, VAT, and TTC with the rate code your TEIF export expects.
- 19% — default for professional and technical services not under a reduced or exempt regime
- 13% — defined categories such as tourism and listed activities—not generic B2B IT
- 7% — primarily goods and specific product classes; verify before using on services
- 0% or hors champ — exports and exempt supplies only when your advisor confirms eligibility
Mixed invoices fail when one project line is 19% and a pass-through disbursement needs different treatment. Split lines before TTN submission; fixes after clearance mean credit notes. Export-of-services to foreign clients depends on place-of-supply rules—do not assume zero VAT because payment is in euros.
Exemptions: context, not interpretation
Some entities use VAT suspension, partial exemption, or sector reliefs. Registration and invoicing discipline differ from staying below a threshold indefinitely. Agriculture, education, health, and finance have specialized rules—your accountant maps NAF codes and contracts. Finance can flag customers with exemption certificates, store expiry dates, and block automatic 19% until the cabinet approves. Document the advisor sign-off in your client file.
TTN and TEIF fields that block clearance
Under El Fatoora, the cleared e-invoice is the issued document. See our TTN El Fatoora SME guide for enrollment; here are fields that cause rejection or audit friction for services firms.
- Seller matricule fiscal and legal name as enrolled on adhesion.elfatoora.tn
- Buyer identifier: matricule fiscal, CIN, or passport rules per buyer type
- Invoice number, issue date, line HT amounts, VAT rate codes, and arithmetic matching TEIF
- Digital signature from an accredited provider before submission
- Post-clearance: TTN reference, QR payload, and timestamp on customer PDFs
Repeated master-data errors: wrong matricule, trade name instead of raison sociale, stale addresses. Validate new clients once in a structured form. When clearance fails, fix customer records—see our TTN submission errors guide—not only resubmit the same XML.
Service invoicing workflow
- Contract link
Tie each tranche to SOW or PO; note refacturé disbursements.
- Draft with correct VAT
Apply cabinet-approved rates; attach delivery proof your sector expects.
- Finance approval
Confirm VAT and retenue à la source flags before clearance.
- TTN clearance
Generate TEIF, sign, submit; proforma only until cleared.
- Accountant export
Send cleared register, payments, and TEJ-relevant extracts on schedule.
Retainers need credit-note discipline when scope shrinks. Corporate AP teams want line detail even on monthly summaries. For subscriptions, define whether each period is a new invoice or renewal numbering your TTN integration supports.
Withholding tax (retenue à la source) on certain service payments is separate from VAT display but must appear consistently on invoices and accountant exports your cabinet uses for annual liasse. Train project leads to never edit cleared invoice PDFs manually—issue avoirs through the same system that submitted TEIF.
Accountant coordination
The accountant Hesabi workflow guide covers RACI and exports. Add for VAT-heavy services: agree CSV or FEC-oriented delivery by T+5 after close; share uncleared TTN queues weekly; document who holds the TUNTRUST certificate; reconcile cash and bank before locking VAT totals. Quarterly sync on DGI and TTN specification changes. TEJ alignment for eligible payments is in our TEJ reporting Tunisia guide.
Common mistakes
- 19% on every line without exemption review
- Final PDFs emailed before TTN clearance
- Project managers picking VAT rates without finance
- Spreadsheet side books disagreeing with cleared e-invoices

What VAT rate applies to standard consulting?
Usually 19% unless your advisor confirms reduced or exempt treatment for a specific activity or client.
Are IT services always at 19%?
Most domestic B2B IT is standard rate, but bundled licenses, training, or export contracts may differ—map each line with your accountant.
Which TTN field causes most rejections?
Incorrect buyer matricule fiscal or name mismatch, then VAT arithmetic not matching TEIF line totals.
What goes to the accountant monthly?
Cleared invoice register, payments, uncleared queue, credit notes, and TEJ extracts if applicable—on an agreed schedule.
Is this tax advice?
No—operational guidance only. Binding tax positions require your expert-comptable or qualified fiscal counsel.
