IRS guides for common tax questions
Start with the official guidance for your topic and tax year. Publication summaries are educational; the details and exceptions matter.
Business owners
Use Publication 334 for small-business tax basics, Publication 463 for travel and vehicle records, Publication 505 for estimates, and Publication 587 for home-office rules.
Retirement and individual returns
Publication 17 covers individual filing. Publications 590-A and 590-B address IRA contributions and distributions. Publication 915 explains Social Security taxability.
