(Update: Free promo is expired, it’s back at $9.99.) Just a quick note that there is a Kindle eBook about tax deductions for small businesses, including self-employed people, that is currently free called Small Business Tax Deduction Secrets by Stephen Nelson, CPA. The author participates in the Bogleheads investment forum under the username SeattleCPA.
I downloaded and skimmed the book briefly, and it does have helpful information for those looking to maximize qualified business expenses and deductions (as you should!). Free for a limited time, so as usual my advice is download now and read later! You can download software to read Kindle books on PC, Mac, smartphones, and tablets.
