Communiqué No. 589 on the Tax Procedure Law, published in the Official Gazette on 31 December 2025 (issue 33124, 5th repeated), rewrote the e-Archive invoice section of the earlier Communiqué No. 509. The change can be summed up in one line: paper invoicing now runs on a timeline that differs by taxpayer group but ends at the same point. For businesses that keep accounts on a balance-sheet basis, that transition was already completed on 1 January 2026. For simplified-procedure and business-account taxpayers, a narrower window remains open until the start of 2027.
Most manufacturing and wholesale SMEs are already inside the e-Invoice/e-Archive system because of turnover thresholds. But businesses with retail sales, a dealer network, or direct invoicing to end consumers need to treat this communiqué as a management issue, not just an accounting one.
What the communiqué actually changed
The section of Communiqué No. 509 titled “Other Invoices Required to Be Issued as e-Archive Invoices” was amended by Communiqué No. 589. At the center of the change are two separate transition timelines:
- Taxpayers keeping accounts on a balance-sheet basis must issue all invoices through e-Archive, regardless of amount, from 1 January 2026 onward.
- Taxpayers under the simplified procedure or the business-account basis may still issue paper invoices for amounts not exceeding 3,000 TL (VAT included) until 31 December 2026; invoices above that threshold must already go through e-Archive.
Both timelines converge on 1 January 2027: from that date, regardless of taxpayer group or invoice amount, all invoices are expected to be issued through e-Archive. In practice, this means paper invoicing is being phased out of Turkish commercial life almost entirely.
Transition timeline by taxpayer group
| Taxpayer group | Paper invoice limit | Full e-Archive requirement |
|---|---|---|
| Balance-sheet basis | None — amount-independent e-Archive since 1 January 2026 | 1 January 2026 |
| Simplified procedure / business-account basis | Paper allowed up to 3,000 TL | 1 January 2027 |
| Invoices to end consumers (B2C) | Same 3,000 TL threshold applies within the relevant group | Follows the group’s timeline |
These figures come directly from Communiqué No. 589. GİB has revised this area of regulation more than once in the past, so confirm the date and threshold that apply to your specific taxpayer category with your accountant or through GİB’s current announcements before you plan around them.
What the 3,000 TL threshold means in practice
This limit matters most for two groups: small businesses that take cash or card payments on the spot and issue an invoice immediately, and contractors working on seasonal or project-based jobs. 3,000 TL is a threshold that a handful of transactions a day can easily cross — particularly for materials, equipment, or service invoices. As a result, many businesses that are technically still classified as “simplified procedure” or “business-account” have effectively already moved to e-Archive during 2026.
One point often gets missed: moving to e-Archive is not a one-time software install, it is a process change. The invoicing flow (who issues an invoice, from which screen, with what approval), the accounting integration, and the archiving obligation all need to be rebuilt together.
Consider a concrete case: a manufacturer-wholesaler issuing 60-70 invoices a day across three sales points. Until now, this business may have issued e-Invoices to larger customers and paper invoices to smaller dealers. As the second group digitalizes in 2026-2027, several sales points need to connect to a single e-Archive account or integrator link at once — raising operational questions around access rights, internet connectivity, and a fallback plan for when the connection drops. Adjusting to the new flow on the shop floor takes as much time as meeting the technical requirement itself.
Is your ERP ready for this shift
For businesses already registered as e-Invoice taxpayers, e-Archive is usually an extension of the same infrastructure — an additional module activated through an integrator or a custom integration. The real risk sits with smaller businesses that have never connected to the e-document system before: moving from a paper invoice book to a digital system can mean entering product/service records, customer data, and tax codes into the system from scratch.
Points worth checking:
- Does your current ERP or accounting software already have an e-Archive module, or do you need an integrator.
- Are your product/service catalog and customer records up to date in a digital system.
- Is the invoice approval flow (who issues, who approves) defined for the new system.
- Can archived invoices be retrieved retroactively if you’re audited.
Treating this transition as part of a broader digital transition investment, rather than a one-off compliance task, tends to produce a more durable outcome — the same infrastructure later becomes the base for an ERP integration that unifies inventory, sales, and finance data.
Integrator selection is where a similar mistake often shows up: businesses frequently pick the cheapest package and run into volume or module limitations months later. Beyond price, three things are worth checking — whether the integrator has a ready-made connection to your ERP, how fast its technical support responds, and how quickly it rolls out GİB’s schema updates (such as UBL-TR code list changes) into its own system. Skip these three, and the small saving up front tends to be repaid later in downtime.
Early migration pays off beyond compliance
Businesses that move to e-Archive early and consistently get an additional benefit: invoice data becomes systematic and queryable. That data can feed directly into sales analysis and cash-flow forecasting. Information that stayed scattered across paper records turns into a single, traceable data set in a digital system — a concrete example of the twin transition approach that links measurement, software, and compliance in one chain.
Frequently Asked Questions
What’s the difference between the balance-sheet basis and the business-account basis?
Balance-sheet taxpayers are generally larger businesses that keep double-entry accounting records. The business-account basis and simplified procedure apply to smaller businesses and self-employed professionals, using a more streamlined record-keeping method. Your accountant or tax registration certificate will confirm which group you fall under.
How do you actually switch to e-Archive?
There are two routes: manual invoicing through GİB’s free e-Archive Portal, or an automated flow connected to your ERP/accounting software via a private integrator or your own custom integration. If invoice volume is low, the portal may be enough; businesses issuing invoices regularly and at volume save time with an integrated setup.
What happens if a business misses the deadline?
Under the Tax Procedure Law, failing to follow the required documentation format carries a risk of a tax irregularity penalty; the exact amount and conditions can change over time, so confirm current rules with your accountant or GİB’s latest announcements. This article is not a substitute for legal or financial advice.
I’m already an e-Invoice taxpayer — do I need to do anything extra for e-Archive?
Usually not — for e-Invoice taxpayers, e-Archive typically runs as an additional module through the same integrator or the GİB portal. It’s still worth testing that invoices issued to end consumers land correctly in e-Archive format.
Could the 3,000 TL threshold change again?
Thresholds like this are revised fairly often through Tax Procedure Law communiqués in Türkiye; the 3,000 TL figure in this article comes from Communiqué No. 589. Confirm the current amount through GİB’s official announcements before applying or planning around it.
