Difference between Input tax and output tax in VATprocessing.

What given in oracle:

Output TAX:  For AP

Suppliers of goods and services must add VAT to their net prices. They must record output VAT for goods on the date that they issue invoices and for services on the date that they receive payment. The amount of VAT is determined by applying specific rates to the net selling prices of certain goods and services.

Input Tax: For AR

Input VAT is the VAT paid by the purchaser of goods and services.

If the purchaser is subject to output VAT, the purchaser can recover input VAT by offsetting it against output VAT. When input VAT exceeds output VAT, the purchaser can forward the VAT balance as a credit toward the tax authority for the next reporting period; or receive a cash refund, depending on the policies of the tax authority.
