Making a profit on your business is always a good thing. But finding out you have to pay extra taxes is not. Luckily, we weren't too surprised about having to pay. I always have our accountant do a review mid-year, and we knew were on track to having to pay.
Luckily, we do have some money put away in savings and business is picking up even more, so we should be able to get it paid off quickly.
The down-side is we will probably have to start paying quarterly payments. Although, having a "forced" tax savings plan may not be a bad thing.
