Integrity can be defined in so many ways, but most of the time I use a question to determine if integrity is in someone's character or in the character of a business. That question is, "Do you do what's right even if no one is looking or even if you know you could get away with something?" If you can consistently answer yes to these questions, then you have integrity. Likewise, if a business can answer yes to these questions, it has integrity.
There are so many opportunities for individuals and businesses alike to be tested in the area of integrity. One of the ways for individuals to be tested is in the area of taxes. Sometimes paying taxes, reporting the proper amounts, and indicating when mistakes are made cause problems for people and eventually lead to even bigger problems. My philosophy is simple. In the bible, the scripture says it is better to be righteous with little than to be unrighteous with much (paraphrased). If you can't be trusted in the area of taxes, there will almost always be other areas that you will do wrong in. Whether it's keeping something that's not yours like a pen, a movie, or a dress, or failing to give the whole truth in a situation, many times these are indicators.
In recent years, we have seen so many CEOs and high-profile people sentenced to prison time due to a lack of integrity. In the end, it's never worth it to mislead or misinform people and it never makes sense to do what's wrong. Trust me, it's a great feeling to be able to sleep at night with a clear conscience.
