Remitian

Remitian — The Standard for Tax Payments Remitian is the AI-powered tax payment platform that connects the entire tax payment ecosystem — firms, taxpayers, and institutions — through one intelligent portal. Most tax software ends at filing. Remitian automates the journey from "ready to file" to "ready to pay." Platform Access Accounting firms, bookkeepers, and wealth managers access Remitian directly to manage every client tax payment from a single dashboard. The platform connects to tax authorities — including the IRS and state agencies — through secure rails and jurisdiction-aware routing. Every payment is initiated, validated, tracked, and confirmed in one place, eliminating fragmented government portals, manual bank entries, and missed deadlines. Firms turn tax payments into a managed, billable service. Bookkeepers scale without added risk. Wealth managers gain full visibility and control over every client obligation. API Access Tax software providers and financial institutions embed Remitian's infrastructure directly into their platforms through a publicly available API. Partners connect payment initiation, validation, and confirmation into their existing workflows — finishing the final mile of tax without owning regulatory complexity. The API acts as a unified gateway to multiple tax authorities, automating routing and compliance across jurisdictions. Unified Taxpayer Experience Whether a firm uses the platform directly or a partner embeds the API, taxpayers receive the same experience: a clear, secure portal to review, authorize, and track every tax payment. No more navigating government websites, juggling portals, or guessing whether a payment was received. Every obligation is visible, every confirmation is instant, and every deadline is managed. All taxes. One portal. No penalties.
