Tax compliance refers to the behavior and actions of taxpayers in fulfilling their tax obligations in accordance with applicable laws and regulations. High tax compliance is crucial to ensuring the smooth flow of state funding, particularly in the motor vehicle sector. This study aims to provide empirical evidence regarding the influence of tax sanctions, tax socialization, and service quality on motor vehicle taxpayer compliance in Denpasar City. The research method used was accidental sampling, with a sample size of 100 respondents determined using the Slovin formula. Data were collected through questionnaires administered to motor vehicle taxpayers, and the data obtained were analyzed using multiple linear regression analysis. The results indicate that tax sanctions, tax socialization, and service quality have a positive influence on motor vehicle taxpayer compliance in Denpasar City. Specifically, the higher the public's understanding of tax sanctions and socialization conducted by the authorities, as well as the better the quality of service provided, the higher the level of taxpayer compliance in fulfilling their tax obligations. This study also shows a strong relationship between these variables in improving tax compliance. The theoretical implications of this study indicate that attribution theory and compliance theory can empirically support the idea that external factors such as sanctions and service quality, as well as educational processes through socialization, play a significant role in improving tax compliance. The practical implications of this study provide broader insights for researchers, the government, and related parties, and serve as a useful reference for stakeholders or future researchers interested in similar topics.

Profit growth is the rate of increase in profit obtained by a company. Profit growth is an important factor in assessing a company's financial performance. This study aims to examine the effect of financial ratios on profit growth in infrastructure sector companies listed on the Indonesia Stock Exchange (IDX) for the period 2019-2022. The research sample used was 20 companies with 80 observation samples. The financial ratios used are liquidity, solvency, profitability, and activity ratios. These financial ratios are proxied by the Current Ratio (CR), Debt to Equity Ratio (DER), Return on Assets (ROA), and Total Asset Turnover (TAT), respectively. Testing was carried out using multiple linear regression analysis. Based on the results of the hypothesis test, it is known that the profitability ratio proxied by Return on Assets (ROA) has a positive effect on profit growth and the activity ratio proxied by Total Asset Turnover (TAT) has a negative effect on profit growth. Other results, namely the liquidity ratio proxied by the Current Ratio (CR) and the solvency ratio proxied by the Debt to Equity Ratio (DER) have no effect on profit growth. These results mean that the profitability ratio and activity ratio can be determinants of profit growth predictors and can be a reference for investors to make investment decisions.
