One of the principal reasons small business owners pay more taxes than necessary is that they don’t take advantage of all of the deductions they’re legally allowed. Often that happens because they can’t prove they are qualified. The most common deductions for small business owners include entertainment, travel, meals, capital assets, home office and health insurance. Travel miles, meals and entertainment deductions require that you maintain a diary with daily entries that tie into receipts and other records. It is important to have a good accountant that understands your business and can get you all the deductions you deserve.
