What your invoice must carry

What GİB requires of an electronic document

  • UBL-TR, signed and exchanged

    Documents are UBL-TR XML, signed, and exchanged through the GİB portal, direct integration or a private integrator. The route you choose is an operational decision, not a formality.

  • The right document for the buyer

    e-Fatura only works when both parties are registered in the GİB system; everyone else needs e-Arşiv. Getting that choice wrong is an invalid document, not a preference.

  • e-Defter and its monthly berat

    Ledgers in GİB-format XBRL-GL with a signed berat uploaded monthly — mandatory for balance-sheet taxpayers, and a place generic systems have nothing to offer.

  • KDV tevkifat on the line

    Partial VAT withholding carries GİB tevkifat codes at line level, with the buyer declaring part of the VAT. A single tax-rate field cannot express it.

The thresholds keep coming down

Türkiye has run mandatory e-invoicing longer than almost anyone, and the practical story is that the turnover bar keeps falling — the general threshold dropped to TRY 3 million, with far lower sector thresholds for e-commerce, motor vehicles, real estate and accommodation, and no threshold at all for fuel distributors and certain intermediaries.

Cross the bar in one year and you go live the following July. Businesses are therefore pulled in on a schedule set by their own growth, which is why "we are too small for this" tends to expire without warning.

Four documents, not one

e-Fatura for registered counterparties, e-Arşiv for everyone else, e-İrsaliye for goods movement above its own turnover bar, and e-SMM for self-employed professionals with no threshold at all. Most businesses end up owing more than one.

They share a signing and transmission path, so the sane way to run them is one system that knows which document a given transaction needs, rather than a separate tool per document type.

Reporting that is not invoicing

Form BA and BS list purchases and sales by counterparty above the monthly threshold, and they have to reconcile with what was actually invoiced. When those listings are assembled by hand from exports, they disagree with the ledger — and the disagreement is what draws attention.

Common questions

Is e-invoicing mandatory in Türkiye?

Yes. Türkiye has run mandatory electronic documents (e-Belge) since 2014, applied by turnover and by sector. The general turnover threshold has dropped to TRY 3 million, with far lower sector thresholds for e-commerce, motor vehicles, real estate and accommodation, and no threshold at all for fuel distributors and certain intermediaries.

What is the difference between e-Fatura and e-Arşiv?

e-Fatura works only when both parties are registered in the GİB system. Everyone else must be invoiced with e-Arşiv. Getting that choice wrong produces an invalid document rather than a stylistic difference, so the system has to decide per counterparty.

When does a Turkish business have to go live?

Cross the turnover bar in one year and you go live the following July. Businesses are therefore pulled in on a schedule set by their own growth, which is why "we are too small for this" tends to expire without warning.

What is e-Defter and its monthly berat?

e-Defter holds the statutory ledgers in GİB-format XBRL-GL, with a signed berat uploaded monthly. It is mandatory for balance-sheet taxpayers, and it is a place where generic systems have nothing to offer.

What is KDV tevkifat and why does it need line-level support?

Partial VAT withholding carries GİB tevkifat codes at line level, with the buyer declaring part of the VAT rather than the seller charging all of it. A single tax-rate field on a document cannot express that split.

Rates, regimes and deadlines in this summary change, and many countries are actively legislating on e-invoicing. This is general information, not tax or legal advice — confirm the current position with the authority named above or with your tax adviser before you rely on it.
