In most countries with a parliamentary system of government, a finance bill can be introduced in the legislative body, such as the parliament, congress, or national assembly, by the government or by individual members of the legislative body.
In countries with a presidential system of government, such as the United States, the president usually proposes the budget and the finance bill, which is then debated and voted on by the legislative body, such as the Congress.
The specific procedures for introducing and passing a finance bill can vary depending on the country’s laws and regulations, as well as the political climate and power dynamics within the legislative body. Generally, the finance bill must be debated, amended, and passed by both houses of the legislature before it can be signed into law by the head of government or head of state.
