Small business taxes made easy

What this book actually teaches

Small Business Taxes Made Easy by Eva Rosenberg — known as "TaxMama" — is built around a single premise: most small business owners are not accountants, and they're going to make the same predictable mistakes unless someone explains not just the rules but the underlying logic. Rosenberg, an enrolled agent who has spent decades advising small business clients and answering tax questions publicly, writes the book as a practitioner-to-owner translation. The goal is to give a self-employed person or small business owner enough fluency to avoid the costly errors, communicate effectively with their CPA, and recognize when they're in over their head.

The book is structured around the lifecycle of a small business tax situation rather than the structure of the tax code. Rosenberg opens with entity selection — the tax implications of operating as a sole proprietor versus an S corporation versus an LLC — and explains the self-employment tax hit that surprises many first-time self-employed workers. The 15.3% self-employment tax (the employee and employer halves of Social Security and Medicare combined) is the first major revelation for many readers, and Rosenberg walks through why S corporation election can reduce it for profitable businesses while explaining the IRS's reasonable compensation requirement that makes the S-corp payroll strategy auditable if abused.

Deductions receive the most sustained treatment. Rosenberg covers vehicle expenses (actual cost versus the standard mileage rate, and why the choice made in year one locks the method for the life of the vehicle), home office deductions with the regular-and-exclusive-use requirement, equipment expensing under Section 179, travel and meals at their applicable deduction percentages, and the deductions most commonly missed — health insurance premiums, retirement contributions through SEP-IRA and Solo 401(k) structures, and startup costs for new businesses. Her treatment of recordkeeping runs throughout: she consistently explains what an IRS audit examiner actually looks for, grounding the documentation guidance in the reality of how audits work rather than abstract compliance principles.

Edition year matters for this title. The Tax Cuts and Jobs Act of 2017 changed the qualified business income (QBI) deduction, meal deduction percentages, bonus depreciation rules, and the standard deduction threshold — all of which affect the analysis in earlier editions. Readers should confirm they have a post-2017 edition.

For first-time self-employed workers, sole proprietors, and small LLC or S-corp owners who want practical guidance rather than a tax law reference, this is a more readable alternative to NOLO's drier treatment. Rosenberg's practitioner voice carries the book — she writes from the taxpayer's perspective, not the preparer's.
