Abstract. Tax is a mandatory payment collected by the government of a country to spend after the betterment of the country. There are two types of taxes, direct and indirect. In this paper we aim to understand the contribution of indirect tax in the economic growth of Bangladesh. What are its positive and negative effects in the economy. The objective of this paper is to analyse and describe the contribution of indirect tax such as vat, Customs Duty to this countries economic growth. Finding and Analysis. The analysis of this study is conducted by comparing the data collected from various trusted websites and articles which specializes in reporting about economic state of Bangladesh. Indirect tax is a type of tax, its burden lies with the end user of a product it is collected by the seller from the consumer. The seller collects it and then forwards the amount to the government with a tax return. In the fiscal year of 2023 – 2024 all the businesses operating in Bangladesh will have to submit vat return each month. In a developing country like Bangladesh the income tax avoidance rate is very high. In the last fiscal year only 1.4 % of people filed tax returns, and in India this percentage was 5.8%. Here is a chart showing the tax revenue generated in the south Asian countries from 1980 to 2018. Here we can see even in the south-east Asian countries Bangladesh generated the least amount of tax. There are two major reasons behind it, one is corruption and the other is willingness to pay tax. Revenue generated from collecting tax also indicates how much the people of the country trusts its government. And tax evasion is mostly done with corruption as a tool. In this circumstance tax revenue cannot bee collected by the government as they want to because the people are unwilling to pay. So, to solve this problem indirect taxes are charged heavily. Because there is no way to evade the indirect tax. The NBR collected 301633 crore taka as VAT and other indirect taxes in the year 2022, which is approximately 67% of the whole amount of tax collected that year. It is because indirect taxes are collected from the end consumer and the tax is added to the final price of a product that is why this is unavoidable. For a sustainable economic growth, the government needs to collect its targeted tax amount or else they will fail to finance the necessary activities to keep a country running. Bangladesh is now under pressure by the international Monetary Fund to collect more tax. The IMF has given a loan of a sum of 4.7 Billion US Dollars. And they are pressurising to reform the tax structure of Bangladesh as a condition of the loans provided. As the government still can not get majority of the individual tax payers to submit tax returns so the government will be depending on the indirect tax to generate greater revenue.
