Changing Your Accountant in Turkey (2026): Handover, e-Ledger and Digital Authority Guide

Regulatory review — 8 September 2026: This guide was checked against the official TÜRMOB and Revenue Administration materials linked below. An engagement’s terms, the parties’ correspondence and the facts may change the result. Seek Turkish legal advice for disputed termination, retention of records, damages or a possible criminal complaint.

Changing your accountant in Turkey is not merely the delivery of a folder. A sound transition ends the existing engagement validly, returns physical and electronic records under a signed protocol, establishes the new e-filing relationship and reviews every digital permission separately.

The accurate answer in 60 seconds

• Article 26 of the Regulation on Working Procedures allows the professional engagement to be terminated for just cause or by mutual consent. Review the contract’s term, notice and termination clauses first.
• After termination, books and records received by the professional must be returned to their owner within one month under a handover protocol. If the handover cannot take place, the Regulation provides for the professional to notify the chamber.
• Do not give the new accountant your personal credentials. Revenue Administration, e-Government and banking passwords, OTPs, financial-seal PINs and electronic-signature private keys must not be shared. Use the formal contract, sub-user, power-of-attorney or electronic-consent mechanisms.
• The transition date is not enough. Record who owns each return, e-ledger and berat obligation by month.
• A fee dispute, the duty to return records, a civil lien argument and criminal liability are distinct legal questions. None should be presented as an automatic result.

When can the professional engagement be changed?

The broad statement “the taxpayer can switch at any time without conditions” is incomplete. Article 26 frames termination around just cause or mutual consent. Professional rules also prevent a practitioner from starting work for a business while another professional engagement remains in force.

A safer sequence is:

1. Review the term, notice and termination provisions in the current service agreement.
2. If relying on just cause, document the facts and dates. Obtain legal advice if the ground may be contested.
3. If a mutual termination is possible, agree the final service period, fee reconciliation and delivery date in the same written record.
4. Align the old engagement’s end and the new engagement’s start without overlap and without leaving a filing or berat gap.

Non-payment of the professional fee may constitute just cause for the accountant to terminate under the Regulation. That makes a separate written reconciliation of the fee balance particularly important.

What does the one-month handover rule require?

Article 26 provides that books and records obtained by the professional are returned to their owners within one month under a handover protocol when the agreement ends. Article 27 separately requires the professional to safeguard entrusted books and records in good faith and return them when the work ends.

Article 5/a of the Disciplinary Regulation treats failure to deliver the business owner’s books and records under a protocol within 30 days of termination as conduct subject to a warning, while separately addressing a professional’s notification to the chamber where delivery could not occur.

Do not use a one-line protocol saying only “the records have been delivered.” Include at least:

• The parties, contractual end date and actual delivery date
• Each physical book or record, with period and quantity
• E-ledger and berat file names, periods, hashes or storage locations
• Returns filed, tax assessments generated and payment status
• Carried-forward VAT, prior-year losses, advance tax and depreciation balances
• Open tax/social-security letters, audits, invitations to explain, incentives or refund files
• Missing items, the responsible person and the completion deadline
• The parties’ reservations and signatures

Delivery can be made to the taxpayer. If the records go directly to the incoming accountant, the authority and capacity of the recipient should be shown in the protocol.

Build a data inventory—not only a paper checklist

The incoming accountant needs records in a usable and verifiable form, not just printed PDFs. Inventory the following by period:

• VAT, withholding and premium service, advance tax and income/corporate tax returns and assessments
• Journal, general ledger and inventory records; closing trial balance and subsidiary ledgers
• E-ledger XML files, berats and Revenue Administration-approved berat files
• E-invoice, e-archive invoice, e-waybill and other e-document archives
• Bank, cash, accounts receivable/payable, inventory, fixed asset and depreciation reconciliations
• Payroll, recruitment/termination, social-security filing and incentive files
• Carried-forward VAT, offset/refund, prior-year loss and non-deductible expense workpapers
• Pending tax audit, inspection, e-notification, litigation or payment-plan records
• Accounting-software backup and export format; reusable data rather than screenshots alone

Personal data and employee files should move only to the necessary recipients through a secure channel.

Digital authority: transfer permission, not passwords

Advice to “collect all passwords” is unsafe. The Revenue Administration’s Interactive Tax Office rules expressly prohibit disclosure, third-party use and transfer of a user’s code and password.

For a transition:

• Establish the appropriate service agreement and Electronic Return Intermediation and Responsibility Agreement with the incoming SMMM; report the required contract details through the Revenue Administration’s system.
• A taxpayer that has its own e-filing user authorization may also have to approve the pending contract in the current Revenue Administration workflow.
• General Communiqué No. 567 allows a professional holding a valid intermediation-responsibility or full-certification agreement to be authorized as a sub-user for specified functions in the Digital Tax Office. It does not authorize delivery of the taxpayer’s master password.
• Review the outgoing professional’s sub-user and other permissions; remove those no longer needed through the current official process.
• Do not share Revenue Administration, e-Government, bank, registered e-mail, e-mail or integrator passwords. Do not send OTPs, recovery codes or private keys.

Interface labels can change. Use the live Revenue Administration screen and current official guidance on the transaction date.

Assign e-ledger and berat responsibility month by month

TÜRMOB’s e-ledger guidance says e-ledger and berat files are, as a rule, signed with the taxpayer’s own qualified electronic signature or financial seal. A permitted professional or service provider may sign for specified periods through a notarised special power of attorney or the electronic consent mechanism determined by the Revenue Administration. The month/year/accounting period covered by the authority must be explicit.

Add a period matrix to the protocol:

A mid-year transition is not automatically defective. The risk comes from leaving period ownership ambiguous. Month-end or year-end may be operationally convenient, but waiting near a statutory filing or upload deadline may create a larger exposure. Decide against the actual calendar.

E-notification responsibility does not simply move

The Revenue Administration states that an electronic notice is deemed served at the end of the fifth day following the date it reaches the electronic address. E-mail and SMS alerts are supporting notifications; they should not be treated as changing the legal deadline.

During the change:

• The taxpayer or legal representative should check unread notices through their own account.
• Confirm that the registered telephone number and e-mail address are current.
• State in the new service agreement which notices the incoming accountant will monitor.
• Do not abandon the taxpayer’s own control on the assumption that “the accountant watches it”; set a responsibility matrix and a backup review day.

What if there is an unpaid professional fee?

The Regulation addresses two matters separately: non-payment may give the professional just cause to terminate, while Articles 26 and 27 require the return of the books and records at the end of the work and a one-month protocol-based handover after termination.

A prudent escalation path is:

1. Request the books and records in writing with a period-and-quantity list.
2. Separate the undisputed fee, disputed fee and delivery inventory in the correspondence.
3. If delivery does not occur, retain the correspondence and apply to the relevant SMMM Chamber.
4. If asserting a civil lien, damages or a criminal offence, have Turkish counsel review the contract, possession and facts.

It is not accurate to say categorically that Turkish Civil Code Article 950 can never apply to any accounting relationship, or that a delayed delivery automatically constitutes breach of trust under Turkish Penal Code Article 155/2. Legal characterization depends on the facts and the competent authorities.

How far does the outgoing accountant’s liability extend?

The transition does not erase prior periods, but the statement “the outgoing accountant is liable for everything they signed for five years” is also too broad.

Under repeated Article 227 of the Tax Procedure Law, financial liability is linked to tax loss arising because information in a signed return is inconsistent with the books and the supporting records. The professional’s actual assignment, documents supplied or required to be supplied, and causation must be assessed on the facts.

The five-year period in Article 114 is generally the tax assessment limitation period. It does not by itself create a separate five-year guarantee making the outgoing accountant responsible for every error. For a prior-period issue, review the relevant period, agreement, signature, document flow and causal link together.

Timing and fees

There is no universal statutory promise that the entire transition will close in three days. The books-and-records rule provides a one-month return period, but the operational transition depends on the volume of files, open reconciliations, e-ledger periods and digital permissions.

The 2026 Minimum Fee Tariff specifies minimum professional fees; it does not prescribe one fixed transition fee. The written fee should reflect the applicable tariff floor, entity type, employees, transaction volume, e-transformation scope and additional services.

A workable transition plan

Before the handover

• Review the agreement and termination basis.
• Map filing, payment and berat deadlines.
• Prepare the fee and service reconciliation.
• Agree the incoming professional’s scope and start date in writing.

On the handover date

• Sign the detailed protocol.
• Count physical records and digital files against the inventory.
• Close the month-by-month e-ledger/berat matrix.
• Complete the new intermediation agreement and required Revenue Administration approvals.
• Share no personal credentials; remove obsolete permissions.

During the first week

• Compare the latest returns with the trial balance.
• Reconcile carried-forward VAT, bank, accounts and payroll.
• Review unread e-notifications and open official correspondence.
• Assign two-person checks for the first three critical deadlines.
