Sound familiar?

Where the confusion usually starts

Most people with a home business don't skip write-offs because they don't care. They skip them because nobody told them what counts, and guessing feels riskier than leaving it out.

The book goes through what counts, what doesn't, and what to write down, in the order a home business actually runs into it. Plain English, no accounting background needed.

It's short enough to read in a weekend, and it's the kind of book you keep on the desk rather than on the shelf.

"Is this a business or a hobby?"

The book explains the test the IRS applies, and why it matters before anything gets claimed.

"Half of it's personal."

Phone, internet, the car, a corner of the house. It covers how mixed-use costs are split and what shows the split is fair.

"Claiming it will get me audited."

Chapter 18 is about surviving an audit, and chapter 27 goes through the myths. A claim with records behind it is a different thing from a risky one.

"My preparer handles that."

Chapter 10 is called Your Tax Preparer is Giving You Bad Advice. Preparers work fast in season and only see what you bring them.
This guides on what to bring them and what to ask.

Is this book for you?

If any of these sound like you, yes.

Not every book is for every reader. Here's who this one is genuinely for.

A job, and something on the side

Tutoring, freelancing, a craft shop. Chapter 13 covers running a business on part-time effort, and what counts when the income is small.

Creating or selling from home

Course creators, affiliate marketers, direct sellers. The book names each of these and covers the costs they usually carry.

Driving or delivering through an app

Rideshare and delivery work get their own section: the car, the phone, and the records that go with them.

Nod at even one? You're exactly who we curated this for.

Before you buy

We'd rather you bought the right book

Even if it isn't this one. Here's the honest version of both sides.

Buy it if

  • You run any kind of business from home in the U.S. and want to understand the write-offs before tax season, not during it.
  • You'd rather walk into your preparer's office with a list of questions prepared.
  • You're in your first year or two of working for yourself.

Skip it if

  • You want line-by-line help filling in a return. The author says plainly that it isn't that kind of book.
  • You already have an accountant who plans with you through the year.

If the left-hand side is you, the rest of this page shows exactly what you get.

What's inside

Content Page

All thirty chapters, as they appear in the book. It opens with Preface and Introduction, and closes with a list of expense categories, footnotes and a note about the author.

HOW THE BOOK IS LAID OUT

Thirty chapters, in five runs

  • 1 to 9: why the rules work the way they do
  • 10 to 13: who this applies to, from gig work to rentals to part-time
  • 14 to 18: proving it's a business, and surviving an audit
  • 19 to 25: the write-offs themselves, one at a time
  • 26 to 30: further strategies, the myths, and what to do next

WHAT YOU GET PER CHAPTER

Short chapters, one topic each

  • A topic per chapter, so you can read the one you need
  • Plain English, with examples from ordinary home businesses
  • Written for U.S. and Canadian readers
  • 195 pages, and it ends with a list of expense categories to work from

WHAT IT DOESN'T DO

It won't fill in your return

  • No line-by-line filing instructions
  • No software walkthrough
  • It explains what counts and what to keep, so the return is easier to hand over
Our curation process

How this book earned its place

Before a title reaches our shelf, we ask four simple questions. Here's how this one answered.

01 ·Is it genuinely useful?

Yes. It takes the expenses home-business owners ask about most and ties each one to the record that supports it.

02 ·Is it clear?

Short chapters, everyday words, and examples from ordinary home businesses rather than corporations.

03 ·Does it respect your time?

Yes. Each chapter covers a specific point and can be turned to when in doubt.

04 ·Would we recommend it to a friend?

Yes. It's the book we'd hand anyone who has just started earning from home, before their first tax season.

GOOD TO KNOW

Common Questions

I've never done my own books. Will I follow it? +

Yes. It's written for beginners, in everyday words, with examples from ordinary home businesses. The Records Kit gives you the logs to start with the same day.

Will claiming more write-offs get me audited? +

There's a chapter on surviving an audit and another on the myths around them. Between them they cover what tends to draw attention, which is usually inconsistencies and claims with nothing behind them, and the records that support what you claim. For your own return, your preparer is the right person to ask.

I started partway through the year. Does it still apply? +

Yes. There's a section on costs from getting started, including some spent before the business officially opened.

Does it have this year's numbers? +

Every order includes our 2026 Quick Sheet with the current mileage rate, 1099 limits and estimated-tax dates, each linked to its IRS page.

Is this tax advice? +

No. It explains how write-offs work so you can have a better conversation with whoever prepares your return. For decisions about your own taxes, talk to a tax professional.

My side income is small. Is it worth reading? +

The book was written with part-time and first-year businesses in mind. There's a section on running one alongside a regular job.

Does it cover my state? +

It focuses on federal rules in the U.S. and on Canada's CRA. State rules vary, so check those with a preparer.

Is this a physical book or an ebook? +

A physical print. The companions are digital downloads you keep forever.

What if I don't like it? +
