Corporate income tax return translation: correct terminology in financial documents

For which procedures is this translation required?

A corporate income tax return is an official declaration showing a company's earnings and tax burden for an accounting period. Companies conducting cross-border business are mainly asked for a translation of this document in the following processes:

• Opening a bank account abroad and applying for credit
• Discussions with foreign investors and prospective partners, and due diligence for company mergers and acquisitions
• Establishing a company, branch or liaison office abroad
• International tender and qualification files
• Applications to foreign tax authorities and official institutions
• Evidence of income in visa and immigration files for company partners and executives

File scope: is the tax return alone sufficient?

The return is rarely sent on its own. Depending on the receiving institution's list, the tax assessment slip, balance sheet, income statement and return annexes are also included in the translation scope. A file delivered with missing annexes prolongs the process through requests for additional documents from the receiving institution.

For this reason, two questions are clarified before translation begins: which documents has the receiving institution listed, and which accounting periods does it require? The scope is defined by these two answers; translating unnecessary annexes is as costly as leaving required ones out.

Established equivalents in financial terminology

Concepts in the return must be rendered in the target language using established international financial reporting equivalents, rather than arbitrary choices. Some of the most common pairings in English are:

• Turkish "Tahakkuk fişi" → Tax Assessment (Accrual) Slip
• Turkish "Kurumlar vergisi beyannamesi" → Corporate Income Tax Return
• Turkish "Geçici vergi" → Advance / Provisional Corporate Tax
• Turkish "Vergi matrahı" → Tax Base
• Turkish "İstisna ve indirimler" → Exemptions and Deductions
• Turkish "Gerçek faydalanıcı" → Ultimate Beneficial Owner
• Turkish "Kanunen kabul edilmeyen giderler" → Non-deductible Expenses

When choosing an equivalent, both the financial function of the line and the terminology used in the destination country are considered; the same Turkish term may have different established equivalents in British and US usage.

Number formats and reproducing tables

In Turkish financial documents, a full stop is the thousands separator and a comma is the decimal separator; this arrangement is reversed in English. For example, the amount 1.250.000,00 TL becomes TRY 1,250,000.00 in the English text. The format is adapted to the target language; the amount itself never changes under any circumstances.

Table headings, line numbers, negative values, footnotes and annex references are preserved in the source layout. When the receiving institution's financial analyst places the translation beside the original, they must be able to match the lines one by one; financial document translation requires traceability as well as readability.

Certification level and confidentiality

Banks and commercial counterparties are usually satisfied with a sworn translation; official institutions, consulates and some tender authorities require notarisation. Whether an apostille is required for use abroad is determined for each file according to the destination country and institution.

The return contains some of the company's most confidential information. Sharing documents only with the team handling the work, destroying drafts at the end of the process and signing a confidentiality undertaking upon request are among the standards of corporate translation services.
