TDS challans are documents rendered by the person deducting tax for making online payments. The introduction of online TDS challans in 2004 makes compliance more accessible and reduces human error. For TDS payments, the challan number ITNS 281 is used. TDS challans can only be downloaded when making online payments. OLTAS or the income tax portal allow the taxpayer to download the challan and check its status. Through this blog, we have discussed different steps to add your challan details using Gen TDS/TCS Software.
