For party-of-one businesses, an accountant can assist with most things money-related so that the business owner can focus on the business. For businesses with more than one employee, an accountant with small business expertise can help with everything from determining the right business structure to filing taxes. For individuals, hiring an accountant may be a harder sell. But financial management can be more difficult than you think, especially with the advent of person-to-person payment and investment apps. Perhaps the biggest reason someone hires an accountant is to help them with taxes, especially if they’re facing complicated tax situations like receiving a large inheritance, giving a large financial gift, correctly filing rental property or navigating capital gains taxes.
