Real estate tax base assessment and evaluation systems are crucial for financing public services and digital economy transformation. To automate and unify complex tax procedures, an intelligent taxation model is needed. Deep learning neural network (DLNN) models have been limited for small-scale, high-dimensional data, but this paper creates an automated model using DLNN, offering superiority, interpretability, and dependability. The model offers lower error levels and high accuracy. The intelligent automated taxation model will improve real estate tax inspection offices efficiency by enabling precise tax base assessments and valuations. Deep learning techniques may enhance real estate price projections, resulting in more precise assessments of taxes. The findings reveal that, compared to other benchmark price predictors, the proposed model achieves greater accuracy (95%-99%) in different datasets and it has the potential to be generalized for real estate taxation authorities and tax inspection offices. The approach is helpful in automated real estate price prediction and taxation applications. This ground-breaking research study proposes a revolutionary strategy that employs deep learning neural network DLNN and challenges the conventional approaches to real estate tax base assessment.
