OpenTaxSolver

• Homepage

OpenTaxSolver (OTS) is a set of programs and templates for helping you fill out your income tax forms. It performs the tedious arithmatic.

OTS is intented to assist those who normally prepare their tax forms themselves, and who generally know on which lines to enter their numbers. It is meant to be used in combination with the instruction booklet corresponding to a given form.

Usage

Example tax-data files and blank starting templates are included under the tax_form_files/ directory. For each filer, save a filled-out template to a new name, such as fed1040_2020.txt. After filling in the lines, run the tax solver on it. From the GUI, this is done by pressing "Compute Tax" button.

Or solvers can be run from the command line, for example, as:

./bin/taxsolve_usfed1040_2020 fed1040_2020.txt

Where fed1040_2020.txt is the name of uour tax-data file, which you edit with any text editor to fill it in or print it out. Output results are saved to ..._out.txt files (e.g., fed1040_2020_out.txt), and can be printed out directly too.

Automatic PDF form fill-out

OTS also contains an automatic PDF form fill-out function.

• Supports all federal forms and state forms
• Saves time by filling out many of the numbers
• You may still need to enter some information or check boxes that are not handled by OTS
• Tested to work properly with many viewers

For automatic fill-out of PDF forms, click the "Print" button and select "Automatically Fill-out PDF Tax-Form", then click "Print".

You can set your preferred PDF viewer by the "Set PDF Viewer" button, or by setting the environment variable PDF_VIEWER.

The automatic fill-out feature is tested to work properly with the following PDF viewers:

• "Atril"
• "Firefox"
• "Google-Chrome"
• "IE"
• "LibreOffice"
• "Safari"
• "Xpdf"
