## Description

Deposit short and the IRS adds 2% to 15% of the shortfall under IRC § 6656.

#### How to use it

 1. Install and activate the plugin.
 2. Edit the page or post where you want the tool and add the shortcode `[readystack_payroll_tax_spreadsheet]`.
    In the block editor, use a Shortcode block.
 3. Open the page and fill in the fields. The results table updates as you type.

#### What you can do with the results

Copy the results table into a client report, a ticket or an email. Change one input
at a time to show what a fix changes before anyone touches the live site, and keep
the table as a dated record of the check.

#### Privacy

The tool runs in the browser of whoever opens the page. The plugin makes no external
requests, sets no cookies, adds no tracking and stores nothing in your database.
It has no settings screen.

#### Source code

The JavaScript and CSS files in the plugin’s assets folder are the complete, human-
readable source. There is no build step: nothing is compiled, bundled or minified,
so what you read is what runs.

## Installation

    screen.
 2. Activate it through the Plugins screen in WordPress.
 3. Add the shortcode `[readystack_payroll_tax_spreadsheet]` to the page where you 
    want the tool.

## FAQ
