About Tax Kit 2026

Tax Kit 2026 is published by Shortell Designs, a small independent publisher that compiles public resources into plain-language checklists and guides.

Shortell Designs has no named staff and makes no claim of tax, legal or accounting credentials. These pages are not tax advice. Each figure and rule is linked to its official source, mostly IRS.gov and SSA.gov. Check the source before you file, or ask a qualified tax professional.

Not affiliated with or endorsed by the IRS, the Social Security Administration or any government agency.

Some page layouts and data tables are built with automated tools. Shortell Designs reviews them by hand against the linked official sources.
