interesting thread.
I am a CA student. May give some advice.
If you are earning over 50L annually, then first congrats for that.
regarding tax if assuming your income is 50L and you declare that as your net income after all deductions then you will have to pay tax of rupees 11,40,000 as per current I.T slabs in india. That's about 23% of your income.
According to income tax, any payment you receive in your bank account for which no traceable source (for I.T. dept.) is declared then it shall be included as income from other sources, so acc. to that all money you withdraw via PP to your bank acc is taxable.
Also somebody was referring to service tax. regarding that you are in field of IM, so whatever you are doing whether freelancing work, or website services or any other that will be covered under Service tax. Acc. to service tax, the service provider is reqd to charge and pay the service tax to the govt. but there is a general exemption limit of rupees 10,00,000. After that service tax will be charged at 12.36% on amount of service provided.
thats all. Now for the savings tax part, here is what you can do (sorry dont have many ideas im still learning):
For service tax, all money you get via paypal or other online payments you withdraw to your bank account can be easily saved from service tax as you can claim that you are providing services online to outside countries people as that will amount to export of services which is completely exempted from the net of service tax. So you dont have to worry about that.
Regarding income tax, there can be several wayouts like claiming deductions for the expenses you pay (can produce fake invoices also), setting it off against other losses (establish some fake prop. business and show loss in that), make multiple paypal accounts on your family members name and spread your income to them that will greatly reduce your tax burden.
Ask your relatives to let you use their PAN card and bank account (your uncle, aunt, grand father, grand mother, parents, spouse, spouse's parents, for detailed relatives list contact any CA).
after that just get the money from your relatives as gift as all gifts that you receive from your relatives is exempted from i.tax (but you can do it not for big sums as your relatives will then be taxed so stay within the lower tax slabs upto 8 lacs only for them).
utilising some of these you can easily cut your tax to like 2-3 lakhs per annum which i feel you should pay. Dont be a complete stealer lol.
