There are 4-5 people living together. Two of them are married to each other. Their incomes fluctuate meaning there are times when only 1-2 people are able to earn for a year. Most of them seem to be doing contract work. Now, when only one person earns, the person pay tax on the entire money, while in reality the money is split among 4-5 people and thus results in much lower tax bracket or maybe even 0% tax. What to do about this situation?
