I am working as a finance executive in a pvt company & have around 6+years of experience in Finance field. But, it is all in Back end operations. I don't have any knowledge on Tax part. I would like to have a thorough knowledge in the areas like, VAT, Service Tax, Professional Tax & sales Tax. From where can I get this training? I don't want only theory training. I want a professional practical training, which can help me in future.
