Hie Preetham, 1) Firstly , it is important to understand that Income Tax return is a document which is filed by you stating your Total Income in a Financial Year through various sources of income i.e Salary , business, house property, etc . (Financial Year is the year of your income , and Assessment Year is the year next to it in which the tax is due . Eg - Financial Year 2014-15, Assessment Year 2015-16) It also states the Taxable income on that salary and the Total tax payable with surcharges and Education Cess . The Taxable income has an exemption of upto 2.5 lakh rupees(For an individual, and not a senior citizen) for this assessment year . You also get tax exemptions on various other investments/allowances such as HRA , Fixed Deposits , Insurance Policies , Provident Funds , Children's Education , etc under various clauses of Section 80. People should know that return is filed to intimate the Government of your tax statements and it should not be confused with the Tax-refund one gets if there is a surplus tax paid by you to the Government . Return is not Refund . 2) Government of India collects Income Tax through three modes : **a) TDS - Tax Deduction at Source .** TDS is the system in which any corporation/business as an Employer is supposed to deduct the Income tax of an Employee from his/her salary at source and submit it to the GOI before the end of Financial Year . The tax is deducted regularly from the employee's salary in certain percentage so as to overcome the liability of Total Tax to be paid by the employer for the Financial Year . The Employer issues a TDS Certificate in the form of Form 16 or Form 16A to the Employee which would be used to claim the TDS by the employee while filing his/her return . Form 16 is the certificate issued for the tax deducted under the head Salaries . Form 16A is issued for tax deducted for income through other sources such as interests on securities,dividends,winnings,etc. If the employee has some extra income through other sources , he/she should intimate the Employer about it before so as to include it for TDS . The total tax paid by you through TDS is also available online on the TRACES portal which is linked to your Bank Account and PAN No. for your convenience . You can also generate and validate your Form 16 / 16A from the website to file your return online . **b) Advance Tax and Self Assessment Tax .** Advance Tax may also be called 'Pay as you earn' Tax . In India one has to estimate his income during the financial year. If your projected tax liability of the current Financial year is more than Rs 10000, you are supposed to pay Advance tax ! This has to be paid in three instalments. 30 % by 15th Sept, 60% minus first instalment by 15th Dec and 100% minus 2nd instalment by 15th March. For individuals who are earning only through salaries , the Advance Tax is taken care of through TDS by the employers and there is hardly any Advance Tax to be paid . But for individuals who have other sources of income , they have to pay Advance Tax . If one forgets to pay he is liable to pay interest @ 1% p.m. Self-Assessment Tax - While filing your Return of Income, one does a computation of income and taxes to be filled in the Return. On computation, sometimes it is noted that the Taxes paid either as Advance Tax or by way of TDS fall short of the Actual Tax Payable . The shortfall so determined is called the Self Assessment Tax which is payable before filing the Return of Income. **c) TCS - Tax Collection at Source .** Tax Collected at Source (TCS) is income tax collected by a Seller from a Payer on sale of certain items. The seller has to collect tax at specified rates from the payer who has purchased these items : Alcoholic liquor for human consumption Tendu leaves Timber obtained under a forest lease Timber obtained by any mode other than under a forest lease Any other forest produce not being timber or tendu leaves Scrap Minerals being coal or lignite or iron ore Scrap Batteries Salaried Individuals are not concerned with TCS . 3) Online Procedure for Filing your Return , Payment of Tax , and viewing/generating your TDS certificate . a) Filing Income Tax Return : The procedure is as simple as it gets .
