The draft of vehicle purchase tax law is released, you need to understand the following points


Yesterday, the Ministry of Finance and the State Administration of Taxation issued the "People's Republic of China Vehicle Purchase Tax Law (Draft for Soliciting Opinions)" to publicly solicit opinions from the public.

车辆购置税

The “Draft for Soliciting Opinions” adopts a tax shift method to increase the “Provisional Regulations on Vehicle Purchase Tax of the People's Republic of China” to the law; the “Draft for Commenting” stipulates that the tax rate for vehicle purchase tax is still 10%.

The "Provisional Regulations of the People's Republic of China on Vehicle Purchase Taxes" promulgated by the State Council in October 2000 stipulates that the vehicle purchase tax shall be taxed on five categories: automobiles, motorcycles, trams, trailers, and agricultural vehicles. According to the state-redeployed vehicle technical standards, trolley buses in agricultural vehicles and trams have been integrated into automobile management. In order to be consistent with the current technical standards for motor vehicles, the “Draft for Comment” changed the object of taxation for vehicle purchase tax to four categories: automobiles, motorcycles, trailers, and trams.

Compared with the "Regulations," the "Draft for Comment" has removed the provisions of the State Administration of Taxation on the minimum taxable prices for taxable vehicles. The official main reason is: At present, the vehicle sales market is highly centralized, price is open and transparent, and invoice management is strict. Taxpayers are less likely to falsely declare taxable prices, and vehicle purchase tax collection management risks are controllable. In order to avoid the difference between the minimum taxable price stipulated by the tax authority and the actual purchase price of the taxpayer, the burden on the taxpayer will be increased and the contradiction between the taxpayers will be reduced, and the minimum taxable price will no longer be set.

At the same time, in order to prevent taxpayers from falsely reporting taxation prices and evading tax evasion, the “Draft for Soliciting Opinions” added that “the taxable vehicle’s taxable price declared by the taxpayer is inconsistent with reality, and the tax authorities shall collect tax "Management Law" and related regulations verify the amount of tax payable ".

In addition, the “Exposure Draft” continues the current provisions of the “Regulations” and specifies four tax exemptions:

1. In accordance with international practice and reciprocity principles, tax exemption shall be imposed on vehicles used by foreign embassies and consulates, consulates, international organization organizations in China and related personnel who are required to be exempted from taxation in accordance with the law;

2. In order to support national defense construction, tax-free vehicles are included in the equipment ordered by the military and the armed police forces;

3. Considering that non-transporting vehicles equipped with fixed devices are mainly used for special operations such as construction and construction, they do not have the main function of carrying people or carrying cargo. Therefore, non-transporting vehicles equipped with fixed devices are exempt from taxation;

4. Other situations where the State Council approves tax exemptions or tax reductions. Provisions such as eligible new-energy vehicles, public steam vehicles, and other temporary purchase tax policies for vehicle purchases may continue to be authorized by the State Council.

The “Draft for Soliciting Opinions” also added “the taxpayer will return the vehicle that has acquired the vehicle purchase tax to the vehicle production and sales enterprise, and may apply to the competent tax authority to refund the tax paid for vehicle purchase tax”, which is conducive to the management according to law. Tax refund.

For the “Draft for Soliciting Opinions,” Cui Dongshu, secretary-general of the National Passenger Vehicle Information Association, believes that it is also a reasonable choice to adopt the tax system shift method to increase the “Regulation on the Purchase of Vehicles” to the law. The implementation of the vehicle purchase tax has been relatively stable for more than a decade. The basic elements of the tax system are reasonable, and the efficiency of collection and management is relatively high. However, the use of links is severely separated from the development of new environments based on cities and passenger cars. It should be improved both in taxation and in the use of links, and it should give the local governments certain tax adjustment rights."

About "The People's Republic of China Vehicle Purchase Tax Law

(Exposure Draft)"

In order to implement the statutory principle of taxation and in accordance with the requirements of the "Implementation Opinions on Implementing the Principle of Statutory Taxation" approved by the Party Central Committee, the Ministry of Finance and the State Administration of Taxation jointly drafted the "People's Republic of China Vehicle Purchase Tax Law (Consultation Draft)" (hereinafter referred to as " Consultation Draft). The explanation is as follows:

I. The Necessity and Feasibility of Formulating the Law

In October 2000, the State Council promulgated the "Provisional Regulations on Vehicle Purchase Tax of the People's Republic of China" (hereinafter referred to as the "Regulations"), which stipulates that from January 1, 2001, vehicle purchase tax shall be levied on units and individuals purchasing taxable vehicles. The purchase tax is imposed on ad valorem and the tax rate is 10%. From 2001 to 2016, the country’s total vehicle purchase tax was 2293.3 billion yuan, an average annual increase of 17%, of which vehicle purchase tax was collected in 2016 of 267.4 billion yuan. The vehicle purchase tax system has played an important role in organizing fiscal revenue, promoting the construction of transportation infrastructure and guiding the development of the automobile industry. Since the promulgation and implementation of the "Regulations", the operation has been relatively stable and standardized, and the conditions for enacting laws based on them have matured.

Formulating a vehicle purchase tax law is an urgent requirement and an important embodiment of implementing the statutory principle of taxation. It is conducive to perfecting the legal system of vehicle purchase tax, enhancing its scientificity, stability and authority, and helping to build a modern financial system that meets the needs of the socialist market economy. The system is conducive to deepening reform and opening up and advancing the modernization of the national governance system and governance capacity.

Second, the overall consideration for the formulation of this law

(1) The "regulations" have been brought into law by adopting a tax shift. The implementation of vehicle purchase tax has been relatively stable for more than a decade. The basic elements of the tax system are basically reasonable and the efficiency of tax collection and management is relatively high. Judging from the actual implementation, there is no need to carry out major reforms, and the current tax system framework and tax burden levels can be kept basically unchanged, and the legislation for vehicle purchase tax transfer can be achieved.

(2) Make reasonable adjustments to a few taxation matters. According to the development of the situation and the actual tax collection and management, the adjustment of the tax vehicle classification and taxation price approval method, etc. are adjusted to make the tax system more scientific and reasonable.

(C) Further improve the collection and management mechanism. The vehicle purchase tax is levied by the tax authorities, but cannot be separated from the cooperation of the public security, customs, industry, and informatization departments. The “Draft for Soliciting Opinions” stipulates the establishment of a mechanism for the coordination of labor collection and management to improve the efficiency of tax collection and management.

Third, the "consultation draft" the main content

(a) About taxpayers. The “Draft for Soliciting Comments” continues the current rules and specifies that taxpayers for purchase tax on vehicles are units and individuals that purchase taxable vehicles in China. Among them, purchase refers to the act of purchasing, importing, self-producing, receiving, awarding, or otherwise obtaining and owning a taxable vehicle. (Article 1, Article 2)

(b) on the object of taxation. The "Regulations" stipulates that taxation targets for vehicle purchase tax are five categories: automobiles, motorcycles, trams, trailers, and agricultural vehicles. According to the state-redeployed vehicle technical standards, trolley buses in agricultural vehicles and trams have been integrated into automobile management. In order to be consistent with the current technical standards for motor vehicles, the “Draft for Comment” changed the object of taxation for vehicle purchase tax to four categories: automobiles, motorcycles, trailers, and trams. (Article 3)

In addition, the "Scope of Levy of Vehicle Purchase Taxes" attached to the "Regulations" has clearly defined the specific scope and standards of taxable vehicles. Considering that the state-issued motor vehicle technical standards already have relevant provisions, and adjustments will be made as the situation evolves, in order to avoid frequent changes to the law due to technical standards adjustments, the “Draft for Comment” no longer attaches to this table.

(c) Regarding taxation prices. According to the different circumstances of the purchase of taxable vehicles, the “Draft for Comments” stipulates four methods for determining the taxation rate for vehicle purchase tax: First, the taxpayer purchases the taxable price of the taxable vehicle for own use and pays the taxpayer for the purchase of the taxable vehicle. The total price and out-of-the-money expenses to the seller do not include the value-added tax; the second is the taxable price of taxable vehicles imported by the taxpayer, which is the sum of the duty-paid price of the taxable vehicle plus the tariff and consumption tax; Third, the taxable price of the self-produced taxable vehicle used by the taxpayer is determined according to the sales price of the taxable vehicle of the same type produced by the taxpayer, excluding the value-added tax. Fourth, the taxpayer is given, awarded or obtained in other ways. The taxable price of the taxable vehicle for own use shall be the price stated in the relevant certificate at the time of purchase of the taxable vehicle, excluding VAT. (Article 6)

Compared with the "Regulations," the "Draft for Comment" has removed the provisions of the State Administration of Taxation on the minimum taxable prices for taxable vehicles. The main reasons are: At present, the vehicle sales market is highly concentrated, the price is open and transparent, and the invoice management is strict. Taxpayers are less likely to falsely report taxable prices. The risk of vehicle purchase tax collection and control is controllable. In order to avoid the difference between the minimum taxable price stipulated by the tax authority and the actual purchase price of the taxpayer, the burden on the taxpayer will be increased and the contradiction between the taxpayers will be reduced, and the minimum taxable price will no longer be set. At the same time, in order to prevent taxpayers from falsely reporting taxation prices and evading tax evasion, the “Draft for Soliciting Opinions” added that “the taxable vehicle’s taxable price declared by the taxpayer is inconsistent with reality, and the tax authorities shall collect tax The "Management Law" and related regulations verify the amount of tax payable". (Article 7)

(d) About the tax rate. The "Draft for Comment" stipulates that the tax rate for vehicle purchase tax is 10%, that is, it maintains the current provisions of the "Regulations" and ensures the smooth implementation of the tax law. (The fifth)

(e) Regarding the amount of tax payable. The "Draft for Comment" stipulates that the amount of tax payable = the taxable price x tax rate. (Article 4)

(6) Tax relief. The “Consultation Draft” continues the current provisions of the “Regulations” and specifies four tax exemptions: First, based on international practice and reciprocity, foreign embassies, consulates, and international organizations should be exempted from taxation in accordance with the law. China’s self-employed vehicles are exempted from taxation by Chinese agencies and related personnel; secondly, they are tax-exempted for supporting the national defense construction, and the vehicles included in the equipment ordering plan for the armed forces and the armed police force; and thirdly, the non-transporting vehicles with fixed devices are mainly used for building construction, etc. Special operations do not have the main function of carrying people or carrying cargo. Therefore, non-transport vehicles with fixed installations are exempted from taxation. Fourth, the State Council approves tax exemptions or tax reductions. Provisions such as eligible new-energy vehicles, public steam vehicles, and other temporary purchase tax policies for vehicle purchases may continue to be authorized by the State Council. (Article 10)

(7) Regarding tax collection and management. The "Draft for Soliciting Comments" clearly states that "the traffic management department of the public security organ shall, when registering for a vehicle, verify the tax payment or tax exemption electronic information provided by the taxation authority; there is no electronic information on tax payment or exemption, and electronic information on tax payment and exemption and taxpayers. If the application for registration information of the vehicle is inconsistent, the traffic management department of the public security organ shall not handle the registration of the vehicle." The "regulation" "The taxpayer shall hold the tax payment certificate or tax exemption certificate issued by the competent tax authority and apply to the vehicle management agency of the public security organ for registration of the vehicle. Where there is no tax payment certificate or tax exemption certificate, the vehicle management agency of the public security organ shall not handle the registration formalities for vehicles. The main reason is that the tax authorities and the traffic management department of the public security organ have realized the real-time exchange of electronic information on taxation of vehicle purchase tax, and the effective management of tax collection can be achieved through information technology means, and the management method of verifying the paper tax payment certification is no longer necessary. (Article 14)

The “Draft for Soliciting Opinions” added “Taxation, Public Security, Commerce, Customs, Industry and Informatization and other departments to establish taxable vehicle information sharing platforms and work coordination mechanisms, timely exchange of taxable vehicles and tax information information, and strengthening vehicle purchase tax collection. The provisions for the management and protection of tax payments in full and on time shall be stipulated. Vehicle production and sales companies shall, in accordance with the requirements of the tax authorities, provide relevant information on the production and sales of taxable vehicles," which will help strengthen the coordination of tax administration and relevant departments and units in their collection and management, and improve cooperation. Collection efficiency. (Article 15)

(8) On the tax refund provisions. The "Draft for Soliciting Opinions" added a new provision that "taxpayers returning vehicles that have acquired vehicle purchase tax to vehicle production and sales enterprises, and may apply to the competent tax authorities for refund of taxes paid on vehicle purchase tax", and is conducive to the management of tax refunds according to law. behavior. (Article 17)

(9) About legal liability. The "Draft for Soliciting Comments" clearly states that taxpayers, vehicle production and sales enterprises and tax authorities, public security organs and traffic management departments and their staff violate the provisions of this Law, and are in accordance with the "Law of the People's Republic of China on Tax Collection and Administration" and "Road Traffic Safety of the People's Republic of China." "Law" and related laws and regulations stipulate legal liability. (Article 19)



CNC Milling

In general, computer numerical control milling machine (CNC) machining is a deductive manufacturing technique that programs 3-axis linkage, complex to 5-axis linkage, drives milling cutters to remove layers from solid blocks called blanks to produce finished parts. CNC milling is one of the main types of CNC Machining, which uses cutting tools that rotate at a speed of several thousand to tens of thousands of revolutions per minute (RPM) to precisely remove materials to obtain parts with complex surfaces. In addition to milling, CNC machining is also equipped with drills, boring tools, thread cutters and other tools to complete different part features at once. CNC machining produces parts based on a computer-aided design (CAD) model that is sent to a CNC machine through computer-aided manufacturing (CAM) software.

CNC Machining centers developed from CNC milling machines. The biggest difference compare to CNC milling machines is that the machining center has the ability to automatically exchange machining tools, by installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in a single clamping device to achieve a variety of machining functions.

High-precision machining center, resolution of 0.1μm, maximum feed speed of 15 ~ 100m / min, positioning accuracy of about 2μm. Between 2 and 10 μm, with a ± 5 μm more, can be called precision grade. FCE equipped with different grade and different size CNC milling center. Take in to account into both economic and quality in parallel.

CNC Finishing surface treatment

Post-processing is the final step in the CNC machining process. In a quick guide, we offer a lot of surface treatments to complete your final parts and get them to meet strict specific requirements. It should be noted that in CNC machining, post-processing is in optional, as the quality of the machined parts is already very high.

Anodized

The anodizing process allows the part to obtain excellent corrosion resistance, increasing the hardness and wear resistance of the surface. Anodizing is also the most common pre-painting treatment, which can help the painted surface to obtain good adhesion. We typically apply two types of anodizing in our production: Type II, corrosion resistant; Type III is thicker, adding a layer of wear resistance. Both anodizing processes can achieve a variety of color effects.

Polishing

Grinding polish, it offers the fastest turnaround parts and does not require post-processing. The surface finish of the grinding part is equivalent to 125 um in Ra, and the requirements can be increased to 63, 32 or 16 um Ra. Minor tool marks may still be visible on the last part.

Powder coatings

Powder Coating is thermoplastic powder spraying directly on the processed part. The sprayed parts are then baked in an oven to form a durable, abrasion- and corrosion-resistant plastic coating. In the powder coating process, its color, brightness, surface roughness can be customized.

Shot blasting

Shot peening is the high-speed spraying of beads of different hardnesses and sizes onto the surface of the part. To get different textures and brightness of the surface. Since the surface has been hit by similar forging beads, the hardness and wear resistance of the surface have also been enhanced.

Design of CNC machining

CNC machining is a universal machining process, especially parts that can be cut and machined can be achieved through CNC, from simple shape shapes to complex curved structures. However, as with every manufacturing technique, CNC machining has some design limitations. We break them down as follows to ensure that your products are optimally designed to better fit the CNC machining process.

General Tolerance

When designing parts, the size of each part is different according to the application environment, working conditions, etc., and the requirements for the machining accuracy of the workpiece are also different. Although CNC machining can achieve very high machining accuracy, we should also be aware that demanding machining accuracy and accuracy (strict product tolerances) usually mean Longer production times and higher costs. If a specific tolerance is not specified in the product design, we recommend choosing at the following levels.

The highest precision of our equipment is 0.001, and the recommended most precise machining requirements do not exceed +/-0.005mm

Interior angle

All internal vertical edges of our products need to have rounded corners instead of right angles. This is because the tools used in CNC milling are cylindrical, which means they cannot produce inner right-angled edges. The fillet required by this process is called the inner corner fillet. When designing parts, the larger the inner corner fillet, the more efficient the production process. Because of the larger fillets, larger diameter milling cutters can be used to increase milling speed, and fewer swaps can be made to improve accuracy.

Undercut

Undercut cannot be machined with standard milling cutters, so the use of retract slots for parts should be avoided when designing CNC machined parts. In particular, for non-standard inner contour shapes, customized machining tools are required, which will greatly increase processing time and costs. Secondly, if undercut can not be avoided, due to the limited length of cnc tools, the undercut can not be too deep. If they are too deep or the location is difficult to reach, they will not be able to be produced because the CNC tool cannot reach the machining location.

Chamber wall thickness

CNC machining requires your part design to meet minimum wall thickness requirements. In general, it is recommended to choose the thickest possible and avoid very thin or characteristic walls. This is because CNC tools processing thin-walled parts will cause vibration deformation, which may cause interruptions or damage, and the size is out of specification. The standard minimum wall thickness for CNC machined metals is 0.030" (0.76 mm) and for plastics is 0.060" (1.5 mm).

Thread

When designing parts, it is useful to choose the largest possible thread size because smaller taps have a higher risk of breaking during production. If possible, avoid using deep hole threads as they lead to higher production costs, especially when custom tools are required.

Metal

In principle, materials with high hardness are easier to process because better processing accuracy can be obtained, but they are limited by the hardness of processing tools, so the hardness of the generally recommended parts is 8 ~ 60HRC, and for metal materials, the hardness is greater than stainless steel Followed by cast iron, followed by copper, and finally aluminum, while the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. Fast production time.

Polymer

Although CNC can process thermoplastics, the material properties of polymers still have many difficulties for CNC processing. First, due to poor thermal conductivity, many thermoplastics melt or bend when in contact with CNC milling machines or drill bits. Secondly, the processing of plastics, because the hardness is low, the size accuracy caused by the knife during product clamping and processing is not high. For those parts that do not have special requirements for the strength and hardness of the metal, thermoplastics can provide a cheaper alternative.

Cost optimization of machined products

Simplify product design

Simplifying product design while taking into account functionality usually saves production time and reduces production costs. Because the manufacture of complex structures and surfaces often requires complex longer passes, more layering to obtain the same fine contour quality. This means higher production costs.

Reduce cutter changes

Using the same milling machine machining features, larger and same internal fillets, can reduce the number of tools used to reduce machining time. For example, if a workpiece needs a 10mm end face milling cutter to process some features, it also needs a spherical milling cutter to process a curved surface, and a 2mm milling cutter to process a fine groove, which will require repeated tool changes and reduce the machining efficiency

Proper material selection

The choice of raw material for machining can have a significant impact on production time and costs for CNC machining. If possible, choose a material with good processability, such as brass or aluminum. For those applications that do not require metal hardness and strength, CNC machining of engineering plastics like PMMA and ABS also helps to reduce costs because the material blank is cheaper, and the processing efficiency is higher.

Tolerance and wall thickness

Higher tolerances and thinner wall thicknesses also increase THE CORRESPONDING CNC machining costs, as it takes time to achieve higher precision cutting. If your product or component can accept a larger size range, choose a lower tolerance to reduce production time and costs. The same is true for wall thickness: a larger wall thickness margin should be chosen.

Choice of surface treatment

Surface treatment is often the final stage of the CNC machining process, which can also affect the cost of your entire project. Choosing less surface treatment for your part or product can lead to better time and cost efficiency. FCE can recommend to you how to optimize the surface treatment to balance the conflict between cost and quality according to your final needs.
