Free downloadable tax forms for individuals and businesses can be found on the Forms and Publications page of the IRS website. Both the current and the previous year's forms are available. All forms are in the Adobe Acrobat PDF format.
PDF format instruction booklets for a majority of the IRS forms are also downloadable from the Forms and Publications page. Clicking on the Accessible tab brings up an assortment of forms and instructions that are available in large print and braille-ready (.brf) formats.
The E-books tab provides several useful texts on subjects such as selling a house, calculating moving expenses and miscellaneous deductions. The e-books are in Adobe Digital Editions (.epub) format, and the IRS claims they have tested them for compatibility with the Apple iPad and Barnes & Noble Nook devices.
