Is Service Tax Applicable on Freelance Income From Outsourced Service?
After reading our service tax guide, you must be confused whether service tax is applicable on freelance income generated from outsource service. Well, again there’s a slight relief for the freelancers. Given the fact that most of the freelancers in the internet industry outsource their services from India to several different countries, they are exempted from Service Tax. As per the Service Tax laws, the Government of India has exempted any Service Tax from all services that are exported out of India.
However, there are certain laws and eligibility criteria to determine whether the service provided falls under “Export of Service” category or not. It is advisable to consult a Chartered Account and he/she may help you further understanding the whole scenario.
