Tax adjustment usually refers to the inconsistency between accounting and tax law and should be adjusted according to the provisions of tax law. There are two differences between accounting and tax law. One is policy differences, such as various expenditures, and accounting standards are higher than those stipulated in the tax law; The other is timing difference, where fixed assets are depreciated in advance, which is shorter than the depreciation period stipulated in the tax law. In the above two cases, tax adjustment will be made when the income tax is settled.

The meaning of tax adjustment is as follows:

1. Tax adjustment is a concept in enterprise income tax. Enterprise income tax is a tax levied on enterprise income. In calculation, the tax law has strict provisions, which are inconsistent with the calculation of total profit in accounting. Therefore, when calculating the taxable income of an enterprise, it should be adjusted according to the provisions of the tax law based on the total accounting profits, so as to calculate the taxable income and pay the enterprise income tax according to the regulations. This process is tax adjustment;

2. Tax adjustment is caused by the difference between accounting system and tax laws and regulations, that is, profit income is adjusted according to relevant laws, including wages, expenses and extracted business entertainment expenses, welfare expenses, trade union expenses, education expenses, depreciation, and various expenses that cannot be deducted before tax. There are still expenses that have not been withdrawn or paid in full, which can be adjusted and paid in full;

3. Tax adjustment generally occurs during the settlement of income tax, which means that the previously declared taxes are not appropriate. During the settlement period, the tax amount shall be adjusted according to the national tax laws and regulations, and all the taxes that should be paid shall be paid, and the taxes that should not be paid shall also be deducted.
