Income Tax Department
The Income Tax Department (also referred to as IT Department; abbreviated as ITD) is a government agency undertaking direct tax collection of the government of India. It functions under the Department of Revenue of the Ministry of Finance. The Income Tax Department is headed by the apex body Central Board of Direct Taxes (CBDT). The main responsibility of the Income Tax Department is to enforce various direct tax laws, most important among these being the Income-tax Act, 1961, to collect revenue for the government of India. It also enforces other economic laws such as the Benami Transactions (Prohibition) Act, 1988, and the Black Money Act, 2015. The Income Tax Act, 1961, has a wide scope and empowers ITD to levy tax on the income of individuals, firms, companies, local authorities, societies, or other artificial juridical persons. Thus, the Income Tax Department influences businesses, professionals, NGOs, income earning citizens, and local authorities, among others. The act empowers the Income Tax Department to tax international businesses and professionals and therefore ITD deals in all matters of double taxation avoidance agreements and various other aspects of international taxation such as transfer pricing. Combating tax evasion and tax avoidance practices is a key duty of ITD to ensure constitutionally guided political economy. One measure to combat aggressive tax avoidance is the general anti avoidance rule (GAAR). History

Ancient times
Taxation has been one of the key function of the sovereign state since ancient times. In Manusmriti, the Manu stated that the king has the sovereign power to levy and collect tax according to sastras. In Bodhayana Dharmasutras, it is mentioned that the king received 1/6th of income from his subjects, which was legally termed as tax. In lieu of this tax, the king had a duty to protect his subjects. According to Kautilya's Arthashastra – an ancient treatise on the study of economics, the art of governance and foreign policy – artha had a much wider significance than wealth. According to him, the power of the government depended upon the strength of its treasury. He stated: "From the treasury comes the power of the government, and the earth, whose ornament is the treasury, is acquired by means of the treasury and army." In Raghuvamsh, Kalidas, eulogising King Dalip, said, "it was only for the good of his subjects that he collected taxes from them just as the sun draws moisture from the earth to give it back a thousand time." Modern times
The 19th century saw the establishment of British rule in India. Following the mutiny of 1857, the British government faced an acute financial crisis. To fill up the treasury, the first Income-tax Act was introduced in February 1860 by James Wilson, who became British-India's first finance minister. The act received the assent of the governor general on 24 July 1860, and came into effect immediately. It was divided into 21 parts consisting of no less than 259 sections. Income was classified under four schedules: i) income from landed property; ii) income from professions and trade; iii) income from securities, annuities and dividends; and iv) income from salaries and pensions. Agricultural income was subject to tax. Subsequently, many laws were brought to streamline income tax laws. For example, the Super-Rich Tax was introduced in 1918, and the new Income-tax Act was passed in 1918. But most important among all these were the Income-tax Act of 1922. This act of 1922 marked an important change from the act of 1918 by shifting the administration of the income tax from the hands of the provincial government to the central government. Another remarkable feature of this act was that the rates were to be enunciated by the annual finance acts instead of in the basic enactment. Again, the new Income-tax Act came in 1939. Contemporary times

The 1922 act was amended not less than twenty nine times between 1939 and 1956. A tax on capital gains was imposed for the first time in 1946, although the concept of ‘capital gains’ has been amended many times by later amendments. In 1956, Mr. Nicholas Kaldor was given the responsibility of investigating the Indian tax system in light of the revenue requirement of the second five-year plan (1956–1961). He submitted an exhaustive report for a coordinated tax system and therefore, the result was the enactment of several taxation acts, viz., the wealth-tax Act 1957, the Expenditure-tax Act, 1957 and the Gift-tax Act, 1958. The Direct Taxes Administration Enquiry Committee, under the chairmanship of Shri Mahavir Tyagi, submitted its report on 30 November 1959, and the recommendations made therein took shape of the Income Tax Act, 1961. The 1961 act came in to force with effect from 1 April 1962 by replacing the Indian Income Tax Act, 1922, which had remained in operation for 40 years. The present law of income tax is governed by the Income Tax Act, 1961, which has 298 sections and four schedules and is applicable to whole of India, including the state of Jammu and Kashmir..

Administration 
Administration in the Income Tax Department (ITD) is run through a statutory body, the Central Board of Direct Taxes (CBDT), at the apex level and 18 territory-based regional headquarters at the field offices level. Besides these are 10 specialised directorates within the Income Tax Department, most extensive and famous among these being the Directorate of Investigation. CBDT
The Central Board of Direct Taxes (CBDT) is a part of the Department of Revenue, Ministry of Finance.

The chairman and members of the CBDT are selected from the Indian Revenue Service (IRS), whose members constitute the top management of the IT Department. The chairman and every member of CBDT are responsible for exercising supervisory control over specialised functional categories at field offices of the IT Department. Various functions and responsibilities of the CBDT are distributed amongst the chairman and six members, with only fundamental issues reserved for collective decision by the CBDT. The areas for collective decision by the CBDT include policy regarding discharge of statutory functions of the CBDT and of the union government under the various direct tax laws. Regional headquarters

As required for efficient and effective administration, these regions have some administrative autonomy to carry out duties assigned by CBDT. Directorates
Directorates are meant to take responsibility of specialised functions. There are 10 specialised directorates within the Income Tax Department, most extensive and famous among these being Directorate of Investigation. Good governance by ITD
The Income Tax Department of the government of India is a leader in good governance. Since large portion of population interacts with department on a yearly basis hence good governance by ITD has improved citizen satisfaction with government functioning. A very well known model of good governance, Sevottam, is being implemented by the Income Tax Department. Sevottam

The Income Tax Department is a leader in implementing Sevottam, which is certification of quality of public service delivery in India. The term Sevottam comes from the Hindi words Seva and Uttam and supposedly means excellence in service delivery. It involves the identification of the services delivered to the citizens, quality of service, its objective, improvement of quality, by using innovative methods for developing business process and more informative with the help of information technology. The citizen-centric approach includes the following three components:
Citizen Charter and Service Standards: Citizen's Charter is being published by ITD from time to time to lay down standards of service delivery to taxpayers. Public Grievances: Income Tax Department has used technology for easy registration and faster disposal of grievances. Various initiatives taken by ITD are: eNivaran lets taxpayers to directly lodge grievance with their concerned ITD officer; Aaykar Seva Kendra (ASK) acts at integrated grievance redressal center; eSahyog allows replies through email to ITD officers on detection of errors in tax filings by taxpayers; and other portals like CPGRAMS. Service Delivery Enablers: This includes customer feedback, employee motivation and infrastructure. Income Tax Department (ITD) functions largely through computer systems and networks; and feedback of taxpayers is taken regularly through Pre-Budget Consultation and regular industry-ministry/department interactions, Outreach Programmes etc. Employee motivation is subjective but good public perception of ITD ensure high employee motivation. Ayakar Seva Kendra (ASK)
Ayakar Seva Kendra (ASK; translated as Income Tax Help Centre) is an integrated model that provides single window system for registration of all applications including those or redressal of grievances as well as receipt of paper return. The assesses can approach ASK and pose all kinds of queries. ASK is available at almost all Income Tax Department offices across the country. Tax Return Preparer Scheme
Launched in 2006 by the Income Tax Department, the Tax Return Preparer Scheme assists small and marginal taxpayers in preparing and filing their tax returns by creating a company of ‘Tax Return Preparers’. Tax Return Preparers are experts in income tax law and in filing of income tax returns. They can charge a maximum fee of Rs. 250, or sometimes nothing. Simplified Income Tax Return Filing
Over the years income tax return filing has been made more simple, convenient, and smart through use of technology. This includes following:
eFiling: eFiling of returns ensured that all returns can be submitted in submitted in digital form at dedicated e-filing website (https://incometaxindiaefiling.gov.in ) without any need of submitting paper returns to Income Tax Department offices. This not only reduced grievances of taxpayers on account of errors in data entry but also made filing of return of income any-time, any-where, convenient exercise. SAHAJ and SUGAM: ITR-1 (SAHAJ) is simplified version of earlier lengthy and complex ITR-1, which is applicable to salaried employees, similarly ITR-4 (SUGAM) is simplified version of ITR-4, which is applicable to small businesses and professionals. eVerification: Use of Aadhar Card or Bank Account is made to ensure verification of ITR by taxpayers. It is user-friendly and removed of the hassle of sending the hard copy of the ITR-V form to CPC Centre at Bengaluru, Karnataka. Taxpayers have also reported that the process of e-verification shortens the time taken for processing of the return and issue of refund. Pre-filled ITR: As part of efforts to popularise the electronic mode of filing Income Tax Returns (ITRs), the CBDT is planning to provide “pre-filled” return forms to filers which will have an automatic upload of data on income and other vitals of a taxpayer. Law enforcement powers of ITD

Taxation law is not only very complex as it requires specialised knowledge and expertise to implement, but also it necessitates various kinds of deterrent actions to ensure compliance by taxpayers. Assessment 
Assessment is done to ensure correct estimation of total taxable income of an assessee (i.e. taxpayer) and it determines amount of tax to be payable by (or to be refunded to) assessee. Most income tax returns filed are processed by the Centralised Processing Center in Bengaluru on the basis of the information provided by the taxpayer. Such automatic processing of returns is called as "summary assessment" and is carried out in accordance with sub-section (1) of section 143 of the Income Tax Act, 1961. When the Income Tax Department requires clarifications or supporting documents on a return filed by the taxpayer, the taxpayer is served a notice under sub-section (2) of section 143 of the Income Tax Act, 1961 to provide evidence in support of the return filed by the taxpayer. When the Income Tax Department requires clarifications from the taxpayer on certain issues for a better assessment of the income of the taxpayer or requiring the taxpayer to file a return of income if he has not filed one already, a notice under sub-section (1) of section 142 is issued to the taxpayer. After the notices mentioned in points (1) and (2) above are complied with, assessment is made under sub-section (3) of section 143. When no compliance is received after the lapse of the time period provided by the assessing officer, assessment is made under section 144. Such assessments are called "scrutiny assessments." Penalties and Prosecutions 

 Penalties: These are financial punishments for non-compliance with any specific provision of the Income-tax Act,and include penalties for not complying with the notices of the assessing officer. Prosecution: Certain actions of taxpayers, for example wilful evasion of tax, are considered as criminal offence by the Income-tax Act and hence these offences result in prosecution. Such offences are considered criminal because they are deemed to be offences perpetrated against the state, as against offences against a person, which results in a civil prosecution. A prosecution is a stricter action than a penalty, and while a penalty only is monetary in nature, a prosecution involves serving jail time for the offences. Surveys 
The department can survey any business premises during the time such place is open for business for physical verification of records and other valuables. Section 133A of the Income Tax Act 1961 provides the department to conduct surveys. Search and Seizure 
The department can search residential and business premises of any taxpayer to check records and valuables to ensure that no evasion of tax is taking place. Section 132 of the Income Tax Act, 1961 provides the department the power to conduct search and seizure. Both the survey action and the search and seizure action are known in the general parlance as "raids." Recent law enforcement actions by ITD
