Suspicions about hidden money should be taken seriously--but also given plenty of thought. Spying on your spouse or going through his personal belongings might only lead to marital trouble where there was once a harmless omission about a small amount of money. If possible, determine the amount of money your spouse should be making based on previous years of income records. This will only work if your spouse has had the same job and has not received a raise. Although, keep in mind, the hidden money could be the raise itself.
Notice any deficit in bank account statements, minus expenses. Note how much money is missing from the main or shared account. This should enable you to conclude whether your spouse is hiding money or overspending. According to MSN Money, large purchases and missing chunks of income are easily noticeable on bank account statements. If a spouse is actually hiding money, it usually goes on for a long time. The money is hidden in small amounts.
According to MSN Money, most people do not hide money in bank accounts because they are so easy to track with statements, receipts and other forms of official documentation. Cash is usually the preferred form if money is to be hidden.
Take advantage of tax time. If you and your spouse have a personal accountant, the spouse that is hiding income might report it to the accountant under your nose, according to MSN Money. However, if you file taxes at home, it would also be possible to leave the forms laying around for a few days after they have been "finished." See if any income numbers change.
Accumulate sufficient evidence so as not to seem controlling and suspicious for no reason. Confront your spouse respectfully. Remember, the hidden money might not even indicate a marital problem, but a communication deficit.
It is possible that your spouse is saving money for a surprise. One spouse might want to surprise another by creating a savings account, for example, for a special vacation the couple determined would be too extravagant at some point. Often, "hiding" money can be completely innocent. One spouse may be the sole earner, for instance, and work plenty of overtime. The "hidden" money may have just been money that was set aside for a personal reward, according to MSN Money. Spouses will usually "hide" this kind of money in amounts of a thousand or maybe a few thousand.
Approach the issue with care. Money is one of the most common causes of marital discord, according to Dr. Phil.
