Do I need a CPA, or can I do my own taxes?
It really depends on your situation. If your taxes are fairly straightforward, you may be able to file them yourself. However, if you have a business, multiple income sources, rental properties, investments, or want to make sure you are taking advantage of all eligible deductions and tax-saving opportunities, working with a CPA can be beneficial.
