Securely import tax documents from brokerage, crypto, and financial accounts

Simplifies and automates the collection of tax documents (1099s, W-2s, etc.) from multiple financial institutions for tax preparation

User installs extension -> Logs into Fifteenth/Haven Tax web app -> Extension detects supported brokerage sites (Robinhood, Fidelity, etc.) -> User initiates import -> Extension facilitates secure document retrieval from third-party financial platforms -> Documents are aggregated in Fifteenth/Haven Tax dashboard for tax filing.

Target users: Individual taxpayers / Tax professionals / Users with investments across multiple brokerage and crypto platforms

Source files (background.js, content.js) are heavily minified and appear to primarily contain the Datadog Browser SDK for analytics/monitoring rather than Fifteenth-specific business logic. The actual application logic likely resides in the web apps (app.fifteenth.com, app.haventax.com). This limits our ability to deeply analyze login flows and paid feature gating within the extension code itself.
Cannot confirm whether the web service has paid tiers without accessing the destination website.
The extension's role appears to be a lightweight bridge/content-script helper rather than a full application, so many features are implemented server-side.

Monetization

No paid features detected

The extension source code contains no evidence of paid features, billing integration, subscription checks, or upgrade prompts. It appears to be a free utility extension that assists with document importing. While the underlying Fifteenth/Haven Tax service may have paid tiers, the extension itself does not gate features or handle payments.

Confidence: 85
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension is a helper for Fifteenth/Haven Tax, a web-based service. The manifest includes content scripts for app.fifteenth.com and app.haventax.com, which are the web applications where users manage their tax imports. To use the core functionality (importing tax documents from brokerages), a user must have an account on the Fifteenth/Haven Tax platform. The extension itself does not implement its own login but relies on the destination service's authentication.
