## **Introduction** 

In Slovenia, the Tax Identification Number (TIN), known locally as “Davčna številka,” is a unique identifier assigned to individuals and legal entities for tax purposes. Possessing the correct TIN is essential for ensuring compliance with Slovenian tax regulations, facilitating accurate tax reporting, and enabling seamless financial transactions. All information provided in this guide is verified from official sources, including the Financial Administration of the Republic of Slovenia (FURS) and other trusted government publications. 

## **Tax Identification Number Types** 

In Slovenia, the primary form of tax identification is the “Davčna številka.” This TIN is utilized universally across various taxpayer categories: 

- **Individuals:** Both residents and non-residents who have tax obligations in Slovenia are assigned a TIN.
- **Legal Entities:** All businesses, including foreign companies operating in Slovenia, must obtain a TIN.

There are no distinct types of TINs; the “Davčna številka” serves as the standard identifier for all taxpayers. 

## **TIN Format and Structure** 

The Slovenian TIN comprises eight digits with the following structure: 

- **First Digit:** Ranges from 1 to 9 and cannot be 0\.
- **Next Six Digits:** Serve as a unique identifier.
- **Final Digit:** Functions as a check digit for validation purposes.

This format ensures a standardized and unique identification for each taxpayer. 

For Value Added Tax (VAT) purposes, the TIN is prefixed with “SI,” resulting in a VAT identification number formatted as “SI12345678.” 

## **Issuing Authority and Registration Process** 

The Financial Administration of the Republic of Slovenia (FURS) is the official body responsible for issuing TINs. Detailed information and resources are available on their official website: FURS Official Website. 

## **Registration Process for Individuals** 

Individuals, including foreign nationals requiring a TIN due to taxable income or property ownership in Slovenia, must complete the following steps: 

1. **Complete the DR-02 Form:** Available in multiple languages on the [eDavki portal](https://edavki.durs.si/).
1. **Submit the Form:** The completed form can be submitted in person, by post, or through an authorized representative to any finance office, excluding the General Financial Office or the Special Financial Office.
1. **Receive the TIN Certificate:** Upon processing, the certificate of the assigned TIN will be provided immediately or sent by post to the address indicated on the form.

Required documents include a valid passport and a copy thereof. 

## **Registration Process for Legal Entities** 

Foreign companies intending to operate in Slovenia must: 

1. **Complete the DR-04 Form:** This form is used for registering the entity in the Slovenian tax system.
1. **Submit the Form:** Deliver the completed form along with necessary documentation either in person or by post to any finance office, excluding the General Financial Office and the Special Financial Office.
1. **Receive the TIN Certificate:** The certificate of assignment will be sent by post to the address provided on the form.

If the application is complete, the TIN is typically issued promptly.
