The tax base for personal income tax is 5,000, and personal income exceeding 5,000 is subject to individual tax according to the corresponding tax rate. Personal income tax cannot be offset against mortgage loans, but special additional deductions for mortgage loans can be offset against taxable income. 1. What is the tax base for personal income tax? Legal analysis: The current personal income tax payment base is 5,000 yuan/month. Legal basis: "Law of the People's Republic of China on Tax Collection Administration" Article 1 In order to strengthen tax collection management, standardize tax collection and payment behavior, ensure national tax revenue, protect the legitimate rights and interests of taxpayers, and promote economic and social development, Enact this law. Article 2 This Law shall apply to the collection and management of various taxes collected by tax authorities in accordance with the law. Article 3 The introduction and suspension of tax collection, as well as tax reductions, exemptions, refunds, and tax repayments shall be implemented in accordance with the provisions of the law; where the law authorizes the State Council to stipulate it, it shall be implemented in accordance with the provisions of the administrative regulations formulated by the State Council. No agency, unit or individual may violate the provisions of laws and administrative regulations and make without authorization any decision to introduce or suspend tax collection, tax reduction, tax exemption, tax refund, tax repayment or other decisions that conflict with tax laws and administrative regulations. Article 4 Laws and administrative regulations stipulate that entities and individuals with tax obligations are taxpayers. Laws and administrative regulations stipulate that entities and individuals with the obligation to withhold and pay, collect and remit taxes are withholding agents. Taxpayers and withholding agents must pay taxes, withhold and remit taxes, and collect and remit taxes in accordance with the provisions of laws and administrative regulations. 2. Can personal income tax be deducted from mortgage loan? Can personal income tax be deducted from mortgage loan? However, personal mortgage interest can be used as a special additional deduction to offset the taxable income of personal income tax. Mortgage interest deducted from personal income tax means that the personal income tax is paid after the mortgage interest is deducted from the monthly salary. In this way, the base of the tax amount becomes smaller, and the individual tax paid is correspondingly smaller. Assume that home buyer A purchases an ordinary residence with a total price of 2.5 million yuan in a first-tier city, with a down payment of 500,000 yuan, and a commercial loan of the remaining 2 million yuan for 20 years. The average monthly repayment amount will be yuan, of which yuan is the interest expense. The pre-tax monthly income of house buyer A is 20,000 yuan. According to the current personal tax policy, taxable yuan such as the four funds and the tax base are deducted. However, if the interest expense of the mortgage loan can be deducted before tax, then other conditions Under the same circumstances, the tax payable by home buyer A is (ten) yuan, which is reduced by yuan, which is equivalent to saving 24% of interest expenses. Compared with buyers who buy ordinary houses, this policy has a more obvious effect of reducing the burden on people who buy high-end houses and have higher wages. 3. Calculation of Personal Income Tax Law The new version of personal tax calculation formula: tax payable = taxable income * applicable tax rate - quick calculation deduction. Among them, taxable income = pre-tax income - three insurances and one fund (Guangzhou is five insurances and one fund) - exemption amount (5,000 yuan) - other deductions determined in accordance with the law - special additional deductions. The specific scope, standards and implementation steps of special additional deductions are still being determined. Suppose A's pre-tax salary income is 10,000 yuan, five social insurances and one fund (calculated in Guangzhou) is 1,000 yuan, and the personal income tax starting point is 5,000 yuan, then his after-tax salary is calculated as follows: Taxable income = 10000-1000-5000=4000 yuan. Referring to the new royalty rate table, that is, in the 3,000-12,000 section, the applicable tax rate is 10, and the quick calculation deduction is 210. Tax payable = 4000*10-210=190 yuan. Actual salary=10000-1000-190=8810 yuan. Let me remind you that individual partnerships need to pay taxes in accordance with the law, but partnerships do not need to pay corporate income tax, but only need to pay personal income tax based on personal income.
