Hi, I am a salary earner and also involved in ecological research and conservation activities during my free time. Some times I receive fees or remuneration for such activities. The remuneration is paid after deducting 10% service tax. Now my annual income from my salary is about 5 lakh. Do I need to add my honorarium to this. Then it crosses 5 lakh and do I need to pay 20% tax for this excess money I earned? If 10 % service tax is already deducted, need i pay 10% more?Please advise.
