What does this module do?
VAT and withholding are not a separate program in Parsek; they work inside e-Invoice, purchase order, incoming e-SMM, progress-payment contract and expense records. The VAT rate and withholding code you pick on a document determine the amounts, and the Finans & Vergi › KDV & Vergi › KDV Özeti screen builds the monthly VAT1 and VAT2 summary from those documents.
Withholding codes and ratios are kept identical to the UBL-TR Code Lists published by the Turkish Revenue Administration (GİB) for e-Invoices (version 1.43, July 2026): 601–627 partial withholding and 801–825 full withholding codes. Parsek does not file the return; you or your accountant file it through GİB's system. Parsek provides a preparation report in which you can check the amounts that go into the return document by document.
Key Features
VAT Inclusive/Exclusive and Valid Rates
In expense, supplier quotation and contract records you can enter amounts VAT-inclusive or VAT-exclusive; for inclusive amounts the net base and VAT are separated. The rate list is 0%, 1%, 10% and 20%; 8% and 18% can only be selected on documents dated before 10.07.2023. The company's default VAT rate and VAT mode are set under Ayarlar › Finans Ayarları; newly created companies default to "VAT exclusive".
Withholding Codes Identical to GİB's Code List
The withholding code selector shows all 52 codes of the GİB code list with their ratios. Some frequently used ones:
- 601 Construction works and engineering, architecture and survey-design services performed with them — 4/10
- 602 Survey, planning-design, consultancy, inspection and similar services — 9/10
- 603 Modification, maintenance and repair of machinery, equipment, fixtures and vehicles — 7/10
- 604 Catering services — 5/10
- 606 Labour supply services — 9/10
- 612 Cleaning services — 9/10
- 614 Shuttle transport services — 5/10
- 624 Freight transport services — 2/10
- 627 Supply of iron and steel products — 5/10
- 801–825 Full-withholding counterparts of the partial-list transactions (except the "other" codes 616 and 626) — 10/10
The code list is maintained platform-wide and updated when GİB's list changes; a document cannot be saved with an expired or inactive code.
Where Withholding Is Entered
- e-Invoice: When the invoice type is "Tevkifat" a code is required; the screen previews VAT, withheld VAT and the VAT actually paid in cash.
- Purchase order: An optional withholding code can be chosen when creating an order from a supplier quotation on an approved request.
- Incoming e-SMM: An optional withholding code is entered next to income-tax withholding on the self-employment receipt.
- Progress-payment contract: The withholding ratio is entered as numerator/denominator (e.g. 4/10); a suggestion based on the buyer's class is shown and you confirm the value to apply.
- Expense: Expenses have no withholding code; you flag a VAT document, deductible VAT and services bought from abroad (which go into VAT2 under reverse charge).
Amounts Calculated on the Server
Withheld VAT (VAT × ratio) and the payable amount (VAT-inclusive total − withheld VAT) are calculated in the database when the record is saved; the figure on screen is only a preview and amounts sent by the browser are ignored. The withholding block is added to the UBL file of an e-Invoice at both document and line level.
VAT Summary: VAT1 and VAT2 Separately
The VAT summary shows output and input VAT (VAT1) separately from VAT owed under withholding and reverse charge on foreign services (VAT2). VAT carried forward moves from month to month (an opening carried-forward amount is entered in Finans Ayarları), and clicking a month opens the documents included in that month. Documents excluded from the return (draft, cancelled, rejected, test), foreign-currency documents without an exchange rate and approved progress payments not yet invoiced appear as warnings in separate lists. The monthly summary and document lists can be downloaded as CSV (Turkish Excel format).
Foreign-Currency Documents
An exchange rate is mandatory on foreign-currency documents; the CBRT (TCMB) buying rate of the bulletin before the document date is suggested. Withholding is calculated in the document currency and the TRY equivalent is kept at the document rate. A document without a rate goes to the "missing rate" list in the VAT summary and is not added to the totals.
Journal Vouchers
If you use the Accounting Bridge, period-based "Fiş üret" turns invoices into vouchers: on sales, VAT net of withholding goes to account 391; on purchases, the full VAT goes to 191 and the withheld part to 360.

Good to know
- Parsek does not produce a VAT return file (XML or BDP) and does not submit returns to GİB; the VAT summary gives a CSV for checking.
- Companies cannot change the withholding code list or the VAT rates; the list is updated platform-wide according to GİB.
- You or your accountant decide which transactions are subject to withholding; on e-Invoices and purchase orders the user selects the code.
- Returns of invoices with withholding are not supported yet; such a return must be issued from your e-document provider's portal.
FAQ
Try this free for 14 days. No credit card required.
Try for Free →- Which withholding codes does Parsek have?
- All codes of GİB's UBL-TR Code Lists version 1.43: 601–627 partial withholding (e.g. 601 construction works 4/10, 612 cleaning 9/10, 624 freight transport 2/10) and 801–825 full withholding (10/10).
- Can we define our own VAT rate or withholding ratio?
- No. The rate and code lists are maintained platform-wide so that no document is issued with a rate that is not on GİB's list. A company only chooses its default rate and VAT mode; on progress-payment contracts the withholding ratio is entered as numerator/denominator.
- How is withholding calculated on a foreign-currency invoice?
- Withholding is calculated in the document currency and the TRY equivalent is kept at the rate entered on the document. The rate is mandatory and the TCMB buying rate of the bulletin before the document date is suggested. A document missing a rate is listed separately in the VAT summary and is not added to the totals.
- Can a document from a past month change later?
- Once you set a period lock, documents dated on or before that date cannot be added, changed or deleted. Because the VAT summary is calculated from the documents, a correction in an unlocked period is reflected in the report automatically.
- Can I upload the CSV from the VAT summary to GİB?
- No. The CSV is prepared in Turkish format so you can check the amounts in Excel; it is not a return file for GİB. The return is filled in on GİB's system.
