Increase Exports

• One of the biggest benefits of GST is that businesses pay less when purchasing goods to resell; in other words, the supplier avoids paying a manufacturer's sales tax, so it is cheaper for businesses who buy the goods to resell. This lowers the cost of exports and, as such, can stimulate exports for the country adopting GST, bringing more money into the country.
  
  

Simplification

• GST is extremely easy to calculate, unlike tax structures that use different tax rates for different products or services and have different rates depending on the price of the product or service. This makes it easier to calculate and plan accordingly, but it also makes it easier for businesses to remain in compliance and for the government to adopt procedures to ensure compliance.
  
  

Reduced Costs

• With regard to businesses, having a single broad tax makes compliance easier, and it reduces the cost of compliance and, in the case of a business with multiple divisions, it can prevent inefficiency stemming from the duplication of efforts to remain in compliance. A company can pass those savings on to its customers or retain the profits and use them to fund expansion, new hires, or employee raises, for instance.
  
  

Lower Income Taxes

• When taxes are levied equally across the board, the government can reduce its operating costs in the same way; duplication goes out the window and ensuring compliance becomes easier. The costs associated with determining tax classifications and managing disputes with regard to tax classification are similarly saved. In turn, the government can lower income taxes at its discretion, a mechanism that can be employed to increase domestic spending or fuel productivity.
