Am i liable for service tax on fees paid

Hello

I am a full time director of a pvt limited along with my wife, also a director. We have been providing software services to a foreign company and the money for services provided are remitted to the company account from the US based 3rd party foreign company.

I pay myself salary/fees by deducting against 94J code via eTDS (10% deduction). Since we are receiving all our revenue from foreign firm, we don't have a service tax for company. My wife and I being full time employees of our firm, are wondering if we have any service tax liability since we are filing under 94J. We are the sole 2 employees and we are the ones who provide the software code for the foreign company.

Any help with this is greatly appreciated.

Thanks
