The effect of tax incentives on tax collection in the comprehensive tax plan using Grounded theory and structural equation model

The purpose of this study is the effect of tax incentives on tax collection in the comprehensive tax plan using Grounded theory and the structural equation model. The method used in this study was a hybrid method including a qualitative method based on the Grounded theory approach and a quantitative method based on the structural equation approach. The research was conducted in three stages. In the first step, which was done qualitatively, the data are collected through structured interviews with a statistical sample (experts). In the second stage, key themes were extracted and converted into the corresponding model. In the last step, the extracted model was tested, which was done quantitatively.

In this research, 98 codes extracted from 12 detailed interviews with experts and specialists in the field of research have become 33 more abstract concepts and finally, 5 categories have been identified. The coefficient of achievement of structural equations shows that the variables of Ease of understanding and usefulness of the rules, Security and speed rules, Rules Support Services, Effectiveness of laws, and Conditions for facilitating the rules have a positive and significant effect on tax payments by taxpayers.
