Taxable amount of enterprise income tax = total profit-non-taxable income-tax-exempt income-various deductions-compensation for losses in previous years. The amount calculated by this formula is the taxable amount of enterprise income tax.
In fact, it is because the government has preferential or encouraging properties for some projects, that is, additional deductions, such as 50% deduction for high-tech development expenses. For example, I spent 6,543,800+000 on high-tech research and development, and I can deduct 6,543,800+05,000 from the technology development expenses.
In the above formula, the technology development fee belongs to various deductions. With the increase of each deduction, the tax payable will decrease accordingly, which is the additional deduction in tax incentives.
The significance of income tax refund is related to the way of income tax declaration.
Income tax is declared in advance in June, April, July and June every year, 65438+ 10. At this time, you need to calculate how much corporate income tax the enterprise needs to pay this quarter, and then pay it in advance, and then settle it at the end of the year, and refund more and make up less. That is, tax refund.
