Some things are best left to a professional
Ironically, sometimes we fall into the habit of thinking that doing things on our own will save us money. But in reality, when you consider the time invested and the potential drawbacks it may actually end up costing you more money in the long run.
Now, for the sake of an example, let's consider the technologically savvy business owner who thinks that Googling how to do taxes now makes them qualified to handle their complex tax situation. Often times, they are then slapped with audits and sometimes even penalties because they miscalculated or failed to do something right. But what's to be expected? 5 minutes in Google isn't going to make up for the years of experience and education that an accountant has.
