About What Is Deductible

What this site is

Tax rules around deductibility are often scattered, vague, or buried in technical language. What Is Deductible organizes common expense questions into simple outcomes: yes, no, or depends.

Each page explains the reasoning in plain English and highlights the conditions that actually matter — business use, personal use thresholds, required forms, and documentation.

What this site isn't

This site is not a substitute for professional tax advice and does not account for every edge case. Tax outcomes can vary based on jurisdiction, income type, and individual circumstances.

The goal is clarity — helping you understand the rules well enough to ask better questions or verify information with an accountant or tax authority.

How to use What Is Deductible

Start with the expense you're curious about. Each lookup page gives you a direct answer first, then explains the conditions, exceptions, and common misunderstandings.

Tip: if a page says "depends," read the conditions carefully — those are usually where people go wrong.

Coverage and jurisdiction

This site primarily covers US federal tax rules as they apply to self-employed individuals, freelancers, and small businesses filing Schedule C. References to specific forms, rates, and rules reflect IRS guidance for the current tax year unless otherwise noted.

A small number of pages include notes on Canadian rules for comparison (for example, the home office Canada vs US page). The site does not cover UK, Australian, or other international tax systems.

If you are outside the US, use this site as a general reference only and confirm deductibility rules with your local tax authority or a qualified tax professional.

Privacy-first by default
