Income tax refund status check is required when you have paid more tax than actual applicable tax. Government collects tax from business in many ways. Advance tax and TDS deductions are some of the common modes of this deduction where companies are asked to pay advance taxes or your customer deducts tax if the annual payout is more than government set limit (till previous financial year the limit was INR: 25000). If the transaction amount is more than this limit, companies deduct TDS from your payment and give it to government.
