As an end user, it allows you to do anything you want without restriction.
For people who redistribute, including end users who modify the kernel: It allows you to give it away or sell it to whoever you like so long as the source code is made available, including for your modifications. The GPL also places a few more restrictions on distributors to make sure they don't keep users from their freedoms.
Linux is not illegal. Linux is a free, public license software modeled on Unix.
Version 2 of the General Public License.
There is no guaranteed warranty under the GNU General Public License, however it does guarantee the ability to modify, publish, and distribute any changes you make under the same license. And AFAIK it does not bar you from charging for said software as long as you also distribute the source code for it.
Completely free. If someone sells you Linux, it is legitimate, however, it will not be for a license to use the software. The GPL is not that kind of license. However, it is still free as in freedom, not free as in beer, meaning it is entirely valid under the GPL to sell Linux.
Unlike Microsoft Windows, you don't need a license to download, use, copy or give away Linux or the many distributions associated with it. Linux is actually the kernel (the heart) from which many distributions of open source operating systems radiate outwards. Ubuntu, Linux Mint, are just two of many popular operating systems that are entirely free.
Examples of public domain software include the GNU/Linux software, which forms a part of many PC operating systems.
Virtually all software is protected by copyright--even Linux (Linux just has a really broad license). There is also a program called Official Copyright Software that helps creators through the process of registering their works.
As far as I can tell, all the tax software I've seen online has been Windows or Mac based. It is possible that some of the online based programs can work on Linux, but this seems to be a general issue with the Linux community.
The Linux kernel is protected by copyright law as a "literary work." However, it was issued under the extraordinarily broad GNU General Public License, which allows free distribution of the code, and grants users permission to modify the code in any way, providing that the resulting code is also distributed under the same license. A discussion of the GPL is linked below.
There are several different tax software compatible with Linux. You can use Tax Act. Is another software that people use when the Linux is not available.

Linux is not a company.
