For businesses, a Digital Signature Certificate (DSC) works much like an individual\u2019s signature, representing the company\u2019s approval on electronic documents.&nbsp;<\/p>\n\n\n\n<p>But how is a DSC registered? Does the process vary between the <a href=\"https:\/\/www.equentis.com\/blog\/new-tax-regime-vs-old-which-is-better\/\">new vs old tax regime<\/a>s? Let\u2019s understand\u2026&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\">What is a Digital Signature Certificate (DSC)?<\/h2>\n\n\n\n<p>A DSC is an electronic form of a physical signature that is used to sign documents digitally. In India, it helps authenticate the identity of the person filing income tax returns or other filings on government portals.<\/p>\n\n\n\n<p>DSC contains details such as the owner\u2019s name, public key, certifying authority, and signature. It is issued as a USB token with a validity of 1 to 2 years (renewable on expiry). Plus, only licensed certifying authorities approved by the Controller of Certifying Authorities (CCA) are allowed to issue these certificates.<\/p>\n\n\n\n<p>There are three classes of DSC:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Class 1 \u2013 For individuals and private subscribers<\/li>\n\n\n\n<li>Class 2 \u2013 For individuals and business professionals<\/li>\n\n\n\n<li>Class 3 \u2013 For individuals and organisations for high-value transactions<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Importance of DSC in Income Tax Filing<\/h3>\n\n\n\n<p>A DSC brings both security and efficiency to the process of filing your tax returns online. It eliminates the risks of forgery, speeds up verification, and is legally valid under the Information Technology Act.<\/p>\n\n\n\n<p>Using a DSC makes filing safer and faster. Many professionals, business owners, and even <a href=\"https:\/\/www.equentis.com\/researchandranking\">stock investment advisor<\/a> firms prefer using DSCs for secure compliance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\">When is DSC Mandatory for Income Tax Filing?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Cases Where DSC is Compulsory<\/h3>\n\n\n\n<p>Under Section 44AB of the Income Tax Act, using a DSC is mandatory for certain categories of taxpayers. If you are a professional or an individual with an annual income of \u20b925 lakh or more, or if you run a business with a turnover of \u20b91 crore or more, you are required to e-file your income tax return using a DSC.<\/p>\n\n\n\n<p>Additionally, if you belong to any of these categories, signing the return with a DSC is mandatory:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An individual, a Hindu Undivided Family (HUF), a Partnership firm, or a Limited Liability Partnership (LLP) whose accounts are audited under Section 44AB<\/li>\n\n\n\n<li>Companies<\/li>\n\n\n\n<li>Political parties<\/li>\n<\/ul>\n\n\n\n<p>When you file and sign your ITR using a DSC, there is no need for further e-verification or for sending a physical copy of ITR-V to the Centralised Processing Centre.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\">Who Can Use DSC for E-Filing?<\/h2>\n\n\n\n<p>Apart from individuals and businesses where DSC is mandatory, many others choose to use a DSC for convenience and better security. Whether you are an investor following advice from a stock investment advisor, a professional claiming <a href=\"https:\/\/www.equentis.com\/blog\/indirect-tax-in-india-everything-you-need-to-know\/\">indirect tax<\/a> credits, or an entity filing for windfall tax adjustments, having a registered DSC simplifies the process.<\/p>\n\n\n\n<p>Before you can use it, you need to register your DSC under your e-filing account. Also note that the tax department now provides an e-filing DSC management utility to help with browser compatibility issues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\">Pre-Requisites Before Registering DSC<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">System Requirements<\/h3>\n\n\n\n<p>Before you start the process of how to register new DSC on income tax portal, check these basics:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You must be registered on the e-filing portal with a valid PAN and password.<\/li>\n\n\n\n<li>DSC should be active, not expired or revoked.<\/li>\n\n\n\n<li>Only Class 2 or Class 3 DSC tokens are accepted.<\/li>\n\n\n\n<li>Plug in the DSC USB token before starting.<\/li>\n\n\n\n<li>Compatible browsers: Chrome, Firefox, Internet Explorer.<\/li>\n\n\n\n<li>Make sure that the PAN on your DSC matches the PAN registered on your income tax portal profile.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Downloading and Installing the DSC Management Utility<\/h3>\n\n\n\n<p>DSC Management Utility (also called emsigner) is a software provided by the Income Tax portal that helps you digitally sign documents and register your DSC securely.
