Can a son who lives with his parents give them his tithe money

Dear Rabbi!<br>Earlier I asked about giving my tithes to my parents because of their financial distress following the birth of an ill baby. The problem is that I work and save all the money except for the tithe. My parents greatly encourage me to save all the money for my future wedding, when I will merit to get married, and for downpayment on an apartment. They want me to live with them so that they’ll cover my expenses. They don’t want me to give them my salary to help cover their living costs. However, if I shop at the supermarket and pay with my credit card, they do not mind, and they do not notice how much money I actually bring home. Is this permissible, and can I eat the food I buy? What products can I buy to reduce the burden on my parents?

Hello,<br>Your parents are very wise and responsible and definitely encourage you to act properly and not to touch the money that you earn and waste it irresponsibly, like most young people do. You keep the money for the time of need, which will come soon, with the help of G-d. <br>As for the matter at hand, purchasing groceries for household needs is the most dignified way to transfer your tithes, and this is also a great way to fulfill this commandment. It is advisable to spend your tithes for the most basic foods and products. The law is that you can use the tithe money to buy anything that your parents normally use. However, since you only cover part of the expenses, it is better to reduce your parents’ burden by purchasing the more basic things. That way, there is no problem with your eating and enjoying the things you buy, it is permitted without any concern. <br>The evil inclination always tries to make a person fool himself, so it is advisable to focus on basic things. That way you won’t be tempted to buy different superfluous products for yourself, while convincing yourself that your parents would have bought this for you, if you had asked them to, or to buy things for the household only to take them for yourself later.
