Tax Topics of Special Interest to Small Businesses

Some of these tax issues are of "special interest" because they are tax rules that can seriously affect your tax standing and prevent your small business from claiming particular deductions (such as being declared an employee or a personal services corporation). Others relate to details about tax topics that only affect small businesses, such as the possibility of changing your business's year end date.

It's not just a matter of certain tax deductions, such as the Small Business Deduction, that are only available to incorporated small businesses, but the fact that being incorporated makes tax management easier.

Canadian GST/HST

Even if your small business is really, really small, you don't want to ignore GST/HST because if you don't collect and remit GST/HST, you can't get back any of the GST/HST your small business pays out – and, of course, because most small businesses don't have a choice.

PST (Provincial Sales Tax)

If your small business is domiciled in one of the provinces that still has retail sales taxes instead of HST (Harmonized Sales Tax), this section is for you. You'll also need to know about provincial sales taxes if your small business sells online in Canada because some provinces expect you to charge and remit their provincial sales tax if you do. (See Charging Provincial Sales Taxes on Online Sales.)
