Free tax software for linux

OpenTaxSolver (OTS) project is a free program for calculating Tax Form entries and tax-owed or refund-due, such as Federal or State personal income taxes.
An optional graphical front-end, OTS_GUI, has been added. Currently, TaxSolver has been updated for the 2005 tax-year for the following forms: US 1040 and Schedules A, B, C, & D.
As well as for California, Massachusetts, New Jersey, and Pennsylvania State Taxes for 2005 tax-year, thanks to contributors. Updates for the following additional states are expected to be posted soon: North Carolina, New York, Ohio, and Virginia. Preliminary versions for Canada and the United Kingdom were posted in previous years and may be updated with help from volunteers.
Motivations:
- To make tax preparation software available for all platforms.
- To provide insight into how our taxes are calculated in clear unambiguous equations/code.
- To avoid invasive, bloated commercial software packages.
- To avoid rewriting our own individual programs each year by combining efforts.
- To provide a simple reliable tax-package requiring only rudimentary knowledge to maintain.
Enhancements:
- Automatic phone credit was added to US1040.
- It will automatically calculate standard one-time phone credit, if not otherwise specified on US1040 line 71.
- The NJ State form F line 5 was fixed.

It grew out of two earlier projects, MiniVend and Tallyman.

- There are other various bugfixes and minor enhancements.

Zen Cart truly is the art of e-commerce; a free, user-friendly, open source shopping cart system. Zen Cart software is being developed by group of like-minded shop owners, programmers, designers, and consultants that think e-commerce could be and should be done differently.
Some "solutions" seem to be complicated programming exercises instead of responding to users needs, Zen Cart puts the merchants and shoppers requirements first. Similarly, other programs are nearly impossible to install and use without an IT degree, Zen Cart can be installed and set-up by anyone with the most basic computer skills. Others are so expensive ... not Zen Cart, its FREE!
Zen Cart will deliver the ultimate online shopping experience to your customers. Navigating through your merchandise offerings is a breeze with Zen Cart, the program provides several "Spotlight" lists in addition to the traditional category to product links. Once a product is added to the shopping cart, secure checkout is a simple 3-step process.
After providing the billing information, your customer chooses the shipping method. (multiple shipping methods including real-time internet shipping quotes are built-in) Next, a payment type is chosen from one of the popular payment modules. (PayPal and AuthorizeNet are just 2 of the included modules) Last, the customer reviews the order, shipping and payment choices, and confirms the order.
You are immediately notified of the order and your customer automatically receives an e-mail confirmation.
Zen Cart addresses many of the goals we set:
- make the program easy to set up
- make it easy to customize
- automate tasks, such as order confirmation
- make navigation simple
- built in promotions; discount coupons, gift certificates, newsletters and product notification
- offer single item specials and storewide discounts (group discounts and quantity discounts - Coming in future editions)
- built in Search Engine Optimization tools
- password protect the Administration Tool (administration "levels" - Coming in future editions)
- support multiple languages, currencies and tax structures
- In short, Zen Cart is shopping cart software the way it should have been all along.
Zen Cart gives web designers a robust and customizable electronic storefront thats easy to keep up-to-date with new features.
It provides usable, intuitive and unobtrusive purchase flows right out of the box based on proven industry best-practices - there are no major revisions required to get things right for your clients!
One of the secrets behind its power lies in our robust template system that "abstracts" the look-and-feel from the code and logic behind Zen Cart. This enables you to give clients a truly custom solution that integrates quickly and perfectly with their existing marketing websites.
Developers are able to deploy cutting edge solutions based on Zen Carts modern standards and technologies. Combining PHP server-side technology with the ability to choose from multiple databases on the back end (coming in future editions, thanks to ADOdb), results in flexible software that you can customize and modify to suit your needs. Minimum/suggested server requirements: PHP 4.1.x or higher (PHP 4.3.3+ for optimal performance), Apache 1.3.x and MySQL 3.2x.x or higher.
Enhancements:
- Two vulnerabilities related to cross site scripting (XSS) have been fixed.
- Officially certified for Paypal Express Checkout (only for North American Paypal accounts as of 20070101).
