Since professional tax is levied by the state government, it tends to differ for various states. Each state declares a slab and the professional tax is deducted on the basis of these slabs. However, there are few states and union territories in India that do not charge professional tax too. It is paid by dividing the annual professional tax due into 12 equal instalments, which are to be paid every month. February, as a month, is an exception where the tax is higher than the other months.
There might be situations where sources of income falling under different sectors are also liable for a separate tax. To cite an instance, in some states, an individual running a business in the transport industry might be liable to pay a professional tax of about Rs. 50 per annum for every vehicles he owns. This may be subject to a cap of Rs. 1,000 per annum.
