Tax calculators for Spanish self-employed workers (invoice, RETA fee, 303, 130, VERI*FACTU) via shortcode. Made for accounting firms.

== Description ==

Add free, always up-to-date calculators for Spanish self-employed workers ("autónomos") and small businesses to your site with a single shortcode. Content and results are in Spanish, because the tools cover Spanish tax and social security rules.

Included tools:

* **Invoice with VAT and income tax withholding** (also in reverse: how much to invoice to receive a given amount).
* **Self-employed social security fee 2026** by real income, using the official brackets (Orden PJC/297/2026).
* **Modelo 303** (quarterly VAT) and **Modelo 130** (quarterly income tax prepayment), with the form boxes.
* **Late payment interest** on unpaid invoices (Ley 3/2004), with the official BOE rate.
* **Hourly rate** for freelancers.
* **"Does VERI*FACTU apply to me?"** test with the 2027 dates.
* **Social security fee regularization** (refund or extra payment?).
* **Digital time-tracking test** (current legal status of the mandatory digital clock-in).
* **Weekly grants and subsidies** (Pro plan).

Usage: `[techscope_calculadora tipo="cuota"]`. Types: `factura`, `cuota`, `303`, `130`, `demora`, `hora`, `verifactu`, `regularizacion`, `fichaje`, `ayudas`.

Each calculator adapts to the available width and to mobile screens. When contribution tables, interest rates or deadlines change, the calculators are updated on the service side: you do not need to update anything.

**Free version:** all calculators, with a small Techscope credit line.
**Pro plan (optional, paid):** your firm's name, colour and contact link on the calculator, no ads or third-party links, plus the weekly grants page. It is purchased at [calculadoras.techscope.es/para-gestorias](https://calculadoras.techscope.es/para-gestorias) and activated by pasting the key under Settings → Calculadoras del Autónomo.

= External service =

This plugin displays the calculators inside an iframe loaded from **calculadoras.techscope.es**, a service run by Techscope (Eric Hernando Aguilar, Barcelona, Spain). The service is required so that the calculators always reflect current regulations without plugin updates.

* Data sent: when a page containing a calculator is displayed, the visitor's browser requests the iframe from the Techscope server, which receives the visitor's IP address and the page URL (referrer) in order to validate the Pro key. Figures typed into a calculator are computed in the visitor's browser and are not sent to any server.
* Cookies: the service does not set cookies or use trackers.
* [Legal notice](https://calculadoras.techscope.es/aviso-legal) · [Privacy policy](https://calculadoras.techscope.es/privacidad)

The plugin does not load any external JavaScript: the iframe is created by a script bundled with the plugin.

== Installation ==

1. Upload the `techscope-calculadoras-del-autonomo` folder to `/wp-content/plugins/`, or install it from Plugins → Add New.
2. Activate the plugin.
3. Paste `[techscope_calculadora tipo="cuota"]` (or any other type) into a page or post. In the block editor, use the "Shortcode" block.

== Frequently Asked Questions ==

= Is it free? =

Yes. All calculators work for free with the "demo" key, which shows a small Techscope credit line. The Pro plan (own branding and weekly grants) is optional and paid.

= Who keeps the data up to date? =

Techscope. Contribution tables and interest rates are updated every January, and relevant regulatory changes as soon as they are published in the Official Gazette (BOE).

= Are the results tax advice? =

No. They are indicative calculations based on the regulations in force. Each calculator says so in its footer and recommends checking each case with an accountant.

= Does it work with Elementor, Divi or other page builders? =

Yes, anywhere you can paste a shortcode.

= Can I place several calculators on the same page? =

Yes, as many as you want, each with its own shortcode.
