TL;DR
Bernard Kamoroff's Write It Off! Deduct It! narrows the focus from his bigger 475 Tax Deductions reference to the specific deductions that matter for home-based businesses. If you run a business from a spare bedroom, kitchen table, or garage workshop, this is the more practical of his two books because every deduction it covers is one you can plausibly claim.
Why It Matters
Home-office and home-business deductions are some of the most under-claimed categories on Schedule C, partly because filers fear an audit and partly because the rules changed after 2017 for W-2 employees. Kamoroff cuts through that fog with clear examples and documentation tips so you can claim what you are entitled to without raising flags.
Key Specs
- Author: Bernard B. Kamoroff, CPA
- Format: paperback and Kindle
- Length: ~200 pages
- Focus: home-based businesses and the home-office deduction
- Audience: U.S. solopreneurs, freelancers, gig workers
Pros
- Tight focus on home-business reality, not generic small-business advice
- Plain-English breakdown of the home-office deduction
- Includes both the simplified and actual-expense methods with examples
- Documentation checklists you can implement same-day
- Affordable — typically cheaper than its bigger sibling
Cons
- Some overlap with 475 Tax Deductions if you own both
- Less helpful for non-home businesses (retail, on-site service)
- Tax thresholds and percentages update yearly
- Lighter on entity-structure choices
Who It's For
Freelancers, consultants, online sellers, content creators, and anyone whose business operates primarily from home. Especially useful if you have never claimed the home-office deduction or you are considering switching from the simplified method to actual expenses.
How to Use It
Read the home-office chapter twice — once for understanding, once with a tape measure to figure out exactly what percentage of your home qualifies. Then build a folder of utility bills, internet bills, and repair receipts you can pull at year-end. Re-scan in December to make sure you have not missed anything.
How It Compares
Narrower in scope than 475 Tax Deductions but more practical for home-based readers. Less strategic than Lower Your Taxes Big Time, but more focused on the deductions you will actually use. Pairs naturally with TurboTax Self-Employed or H&R Block Self-Employed software.
Bottom Line
If your business runs from home, this is one of the highest-ROI books in your tax library. It will likely pay for itself the first year you correctly claim a home-office deduction you previously skipped.
