Availibility of Basic Exemption limit...

1. Non-residents sportsman are specifically covered u/s 115BBA. Any income in the nature of participation in the game, advertisement, contribution to any article in India will be covered under this section. 
2. Tax will need to be deducted by the payer at the time of payment @ 20% u/s 194E and surcharge and education cess should also be included and arrive at the final rate of tax based on the income of the Non-resident sportsman. 
3. Basic exemption limit will not be available for such non-residents sportsman and tax will need to be paid at flat rates and there is no need for filing the ROI if his income consists only of the above income. 
4. Before concluding, make sure he falls within the Non-resident category and also qualifies as a sportsman and his income falls within the ambit of sec 115BBA. 
Please correct me if the above solution has an alternative view.
