Do you need gtag.js to use Tag Manager?

If you currently use Tag Manager, you should continue to do so. Google Ads and Google Marketing Platform tags are fully supported by Tag Manager, and there is no need to deploy additional gtag.js-based code on your site if Tag Manager is already in use. If you’re already using gtag.js, you can always upgrade to Tag Manager at a later date.
