The short answer Systems CPA acts as Turkish local tax counsel for international law firms, foreign accounting firms and in-house tax teams. We provide independent, CPA-signed Turkish tax opinions, co-sourced reviews run alongside your team, and Turkish tax sections you incorporate into your own advice — with the Turkish professional who is responsible for the answer always clearly identified.

In one minute

  • Built for professionals: we answer the Turkish question you scope, in English, in a format your client file can absorb.
  • Independent: we do not compete for your client’s general mandate in their home country.
  • Three models: independent opinion, co-sourced review, or Turkish input for your own deliverable.
  • Conflicts checked and confidentiality agreed before any documents are shared.

Who we support

  • International law firms advising on cross-border transactions, employment moves, distribution and licensing agreements, and disputes with a Turkish tax element.
  • Foreign CPA and accounting firms whose clients hire in Turkey, sell to Turkish customers or receive Turkish payments, and who need a local position for their own advice or audit.
  • In-house tax teams of multinationals that want an independent Turkish view before a decision, a filing or an audit discussion.
  • Corporate service providers and M&A advisers who need Turkish tax diligence input. For partnership and network discussions, see international partnerships.

Three ways to work with us

ModelWhat you getBest when
1. Independent Turkish tax opinionA full, CPA-signed opinion addressed to you or your client (see the opinion service)The client, a court, an auditor or a counterparty needs a separately signed Turkish view
2. Co-sourced reviewWe review documents and model the Turkish position with your team; shared working papers; joint callsTransactions, restructurings and diligence with tight timelines
3. Turkish input for your deliverableA Turkish tax memo you incorporate into your own advice, with our name and licence identified as the source of the Turkish analysisYour firm owns the client relationship and the overall advice

Who signs, who is responsible

Turkish tax advice is a regulated professional activity. Under Law No. 3568, accounting and tax advisory work in Turkey is reserved to licensed professionals, and the professional who signs carries the responsibility. So in every model:

  • The Turkish analysis is prepared and signed by a licensed Turkish CPA, and the underlying signed memo stays on file.
  • Where the Turkish section appears inside your deliverable, it identifies Systems CPA as the source of the Turkish analysis — we do not supply anonymous “ghost” opinions.
  • Where a document must be certified by a sworn CPA (YMM) — for example for certain VAT refund files — we coordinate that certification and say so.
  • Reliance, liability and confidentiality are set out in a short engagement letter before work starts.
Evren Özmen’s note from practice: foreign firms sometimes ask for Turkish advice “without your name on it”. We understand the client-relationship concern, but an unsigned Turkish view is worth very little when the tax office, an auditor or the other side’s adviser tests it. The model that works is your brand on the advice and our licence on the Turkish part.

Typical matters

MatterTurkish tax question
Employee relocation to TurkeyPE and dependent-agent risk, payroll withholding and social security, treaty residence
Distribution / licence agreementWithholding on royalties vs business profits, VAT reverse charge, stamp duty on the contract
Share sale involving a Turkish companyTax on the gain for a non-resident seller, treaty allocation, filing mechanics
Intercompany service chargesDeductibility, withholding, VAT and transfer pricing documentation
Dispute or tax auditTechnical position paper, settlement (uzlaşma) strategy support, co-working with Turkish litigation counsel
Market entry without an entityServing Turkish customers: VAT, PE and contractor status

How a referral runs

  1. Conflict check and NDA. Names of parties first; we confirm no conflict before seeing documents.
  2. Scope note. You send the question as you want it answered; we return the scope, document list, delivery date and fixed fee.
  3. Work in your format. Memo, opinion, comment layer on your draft, or a section for your report — and calls with you or the client as agreed.
  4. Delivery and stand-by. Signed Turkish analysis delivered; follow-up questions within scope included until the matter closes.

What drives the cost

  • Model chosen (input memo, co-sourced review or full opinion)
  • Number of Turkish taxes and treaty layers involved
  • Document volume and language (Turkish source documents need review in the original)
  • Reliance requested by third parties
  • Timeline — transaction deadlines are scoped up front

Repeat referrers can agree framework terms so each new matter starts with a one-page scope note. We do not publish fees.

Case analyses

Case 1 · London law firm · anonymised
Facts
A law firm advising a European buyer needed the Turkish tax position on a non-resident seller’s gain and on historical intercompany charges of the Turkish target, within a two-week signing window.
The obvious answer
“The treaty gives taxing rights to the seller’s state, so Turkish tax is not our problem.”
Why that was not enough
The treaty question was only half of it: the target’s own historical exposures (undocumented management fees, missing reverse-charge VAT) sat inside the company the buyer was acquiring.
Structure adopted
A co-sourced review: a short Turkish memo on the seller-side gain for the law firm’s SPA drafting, and a list of quantified target exposures that went into the tax indemnity and price discussion.
Case 2 · Foreign accounting firm · anonymised
Facts
A European accounting firm’s client hired two engineers in Turkey through a contractor model and the firm wanted to cover the Turkish angle in its own year-end advice.
The obvious answer
“Contractors, so no employment and no PE.”
Why that failed
Exclusivity, fixed hours and integration into the client’s team pointed towards disguised employment and potential PE exposure.
Structure adopted
A Turkish input memo identified as Systems CPA analysis, incorporated in the firm’s advice, recommending an employer-of-record bridge and a decision point for a Turkish entity (see EOR vs own entity).

What happens if…

What happens if our client wants to contact you directly?

Only if you agree. The engagement letter sets who the client is and who communicates with whom; we do not solicit your client for other work.

What happens if the Turkish answer conflicts with the advice we already gave?

We tell you first, privately, with the reasoning and the sources, so you can decide how to address it with your client.

What happens if a Turkish legal opinion is also needed?

We coordinate with your Turkish law firm, or introduce one, and keep tax and legal sections consistent.

Frequently asked questions

Can a foreign law firm engage a Turkish CPA for its client's tax question?

Yes. The law firm can engage Systems CPA directly for its client’s matter, or the client can engage us; who the client is, reliance and confidentiality are set out in a short engagement letter.

Do you provide white-label Turkish tax opinions?

We provide Turkish tax input that you can incorporate into your own advice, but the Turkish analysis is always identified as prepared and signed by a licensed Turkish CPA. We do not supply anonymous opinions.

Who is responsible for the Turkish tax analysis?

The licensed Turkish CPA who signs it — Evren Özmen, TÜRMOB Reg. No. 35675 — under Law No. 3568.

Do you give Turkish legal opinions?

No. Turkish legal opinions on corporate, contract or litigation matters must come from a Turkish lawyer. We work alongside your Turkish counsel on the tax side.

Do you compete with the referring firm for the client?

No. We do not solicit the referred client for work outside the Turkish matter and communicate with the client only as agreed with you.

Can repeat referrers agree standard terms?

Yes. Framework terms let each new matter start with a one-page scope note; fees are confirmed privately.

Need Turkish tax input for a client matter?

Send the parties’ names for a conflict check and a one-paragraph description of the question. We reply with scope, timing and a fixed fee — confirmed privately.
