**TaxHacker is released under the permissive MIT License, which allows unrestricted commercial and private use provided that the original copyright notice is preserved.**

The `vas3k/TaxHacker` repository is an open-source project governed by clear licensing terms defined in multiple locations throughout the codebase. Whether you are deploying the application for personal finance tracking or integrating it into a commercial workflow, understanding the TaxHacker license ensures compliance with its minimal attribution requirements.

## Where the TaxHacker License Is Declared

The MIT License status is formally declared across three canonical locations in the repository root.

### The LICENSE File

The full legal text resides in the repository’s `LICENSE` file. According to the source code, this file begins with the explicit header "MIT License" and contains the complete legal text governing distribution and use. When cloning `vas3k/TaxHacker`, this file sits at the repository root and serves as the primary legal document.

### README.md Documentation

The project's [`README.md`](https://github.com/vas3k/TaxHacker/blob/main/README.md) includes a dedicated "📄 License" section that references the MIT License. This section provides human-readable context and typically includes a badge linking to the full license text, making the TaxHacker license status immediately visible to repository visitors.

### package.json Metadata

For automated tooling and package managers, the [`package.json`](https://github.com/vas3k/TaxHacker/blob/main/package.json) file explicitly declares `"license": "MIT"` within its metadata fields. This machine-readable declaration allows dependency scanners and build tools to programmatically verify compliance without parsing full license text.

## MIT License Permissions and Obligations

The MIT License is a permissive open-source license that imposes minimal restrictions. Key characteristics include:

- **Unrestricted use**: You may use TaxHacker for private, academic, or commercial purposes without seeking additional permission.
- **Modification rights**: You are free to fork, modify, and distribute derivative works of the codebase.
- **Distribution freedom**: The software can be bundled or redistributed in source or binary form.
- **Attribution requirement**: All copies must include the original copyright notice and permission notice found in the `LICENSE` file.

Notably, the MIT License does not require you to release modified source code, making it compatible with proprietary applications.

## Programmatically Verifying the TaxHacker License

You can confirm the license status programmatically by reading the repository's license file. The following Node.js script demonstrates how to extract the license header from a local clone of `vas3k/TaxHacker`:

```javascript
import fs from 'node:fs/promises';
import path from 'node:path';

async function getLicense() {
  const licensePath = path.resolve('LICENSE');
  const content = await fs.readFile(licensePath, 'utf8');
  console.log('License header:', content.split('\n')[0]); // → MIT License
}

getLicense().catch(console.error);

```

When executed in the project root, this script outputs the first line of the `LICENSE` file, confirming the MIT License designation as implemented in the repository.

## Summary

- **TaxHacker uses the MIT License**, a permissive open-source license maintained in the `LICENSE` file at the repository root.
- **Three locations confirm the license**: the `LICENSE` file, the [`README.md`](https://github.com/vas3k/TaxHacker/blob/main/README.md) section "📄 License", and the [`package.json`](https://github.com/vas3k/TaxHacker/blob/main/package.json) metadata field.
- **Commercial use is permitted** without requiring source code disclosure or modification sharing.
- **Attribution is required** in the form of preserving the original copyright and permission notices in all copies.

## Frequently Asked Questions

### Is TaxHacker free for commercial use?

Yes. The MIT License explicitly permits commercial use, modification, and distribution without requiring payment or additional licensing fees. You may integrate TaxHacker into proprietary systems or sell services built upon it, provided you retain the original copyright notice found in the `LICENSE` file.

### Where is the TaxHacker license documented?

The license is documented in three primary locations within the repository. The `LICENSE` file contains the full MIT legal text, while the [`README.md`](https://github.com/vas3k/TaxHacker/blob/main/README.md) references it under the "📄 License" section and the [`package.json`](https://github.com/vas3k/TaxHacker/blob/main/package.json) declares it for automated tooling.

### Do I need to contribute modifications back to the TaxHacker project?

No. The MIT License does not impose copyleft requirements, meaning you can modify the code and keep changes private. While contributing improvements back to `vas3k/TaxHacker` is encouraged by the community, it is not a legal obligation of the license.

### What are the attribution requirements for TaxHacker?
