Your grandmother slides an envelope across the kitchen table on your birthday. Inside is a card with a puppy on it, her looping handwriting, and a check for one hundred dollars. Or maybe it is wedding season and you and your new spouse come home to a stack of cards, some with twenties folded inside, one with a check big enough to make you both go quiet. Or a friend sends you fifty dollars on Venmo just because you had a rough week. However it arrives, at some point a quiet question shows up right behind the gratitude. Should I give a portion of this? Is this the kind of money I am supposed to tithe on, or is that overthinking a kind gesture?
It is a good and honest question, and it deserves a real answer rather than a reflex. Let us start where a Christian ought to start, with what God actually says about the heart behind giving.
"Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver."
2 Corinthians 9:7 (KJV)
Hold onto that phrase, not of necessity. The Apostle Paul is describing giving that flows from a settled decision in the heart, not from a rule pressing on you from outside. That single verse reframes the whole question. The issue is not first whether a gift technically qualifies for a tithe. The issue is what you can purpose in your heart to give cheerfully. We will get to the practical math, and we will take it seriously. But we begin with the heart, because that is where God begins.
Part of what makes this question feel slippery is that a personal cash gift is genuinely a different kind of money than a paycheck, and that is true both in the Bible and in the tax code. Let us take the plain, practical side first, because it clears away a lot of confusion.
Under United States tax law, a gift you receive is not taxable income to you. When your grandmother gives you that hundred dollars, you do not report it on your tax return, and you owe no income tax on it. The Internal Revenue Service is explicit that the person who receives a gift generally does not owe gift tax and does not treat the gift as income. Any tax responsibility for a gift belongs to the giver, not the receiver, and it only comes into play for very large gifts.
This matters for our question in a simple way. When you sit down to think about giving, the full amount of the gift is already yours, free and clear. You are not deciding what to do with pre-tax money or with someone else's obligation. You are deciding what to do with a clean gift that God, through another person, has placed in your hands.
The Bible draws a similar, though not identical, line. The tithe in the Law of Moses was tied to your increase. Read the language carefully.
"Honour the LORD with thy substance, and with the firstfruits of all thine increase:"
Proverbs 3:9 (KJV)
Firstfruits of your increase. In an agricultural world, that meant the harvest that came up from your fields and the young that were born to your flocks. It was the yield of your labor and your land, the new gain that came in over a season. A one time present from a relative is not obviously the same category as a harvest. It is closer to what we would today simply call a gift, a transfer of kindness rather than a wage or a profit. So when someone asks whether the tithe strictly commands a portion of birthday money, the honest answer is that the Law never addresses birthday money at all. There is no chapter and verse that reads, tithe on the cash in the card.
Here is a piece that often gets tangled, so it is worth a clear paragraph. People sometimes worry that grandma has to pay a tax for giving them money, or that they themselves might owe something. For ordinary gifts, both worries are unfounded. The gift tax rules apply to the giver, and only kick in above an annual threshold. In 2026 the annual gift tax exclusion is eighteen thousand dollars per recipient, which means a person can give up to that amount to any one individual in a year without any gift tax filing at all. A married couple can combine their exclusions and give roughly double to the same person. The vast majority of birthday checks, graduation gifts, and cards with cash are nowhere near this line.
Even above the exclusion, the giver usually does not write a check to the government. They simply file a form that counts the excess against a very large lifetime exemption. Practically speaking, for the everyday gifts this article is about, neither the giver nor the receiver owes a dime in tax. The whole amount is a clean blessing, which brings us right back to the spiritual question, now unclouded by tax fears.
To answer the giving question well, it helps to see two threads in Scripture and let them speak together rather than forcing them into a single formula.
The first thread is the tithe. Under the Law, God's people set apart a tenth of their increase for the Lord and for the work He commanded. It was concrete, countable, and tied to what the land and the herd produced. The tithe taught Israel that the first and best belonged to God, and that all their increase came from His hand in the first place. That principle, honor the Lord from the top of what you gain, still forms hearts today. Many faithful Christians keep a tithe as a steady discipline precisely because it takes the guesswork out and keeps generosity from drifting.
The second thread is grace giving, which comes into fuller flower in the New Testament. When Paul writes to the Corinthians about a collection for suffering believers, he does not hand them a percentage. He appeals to their willingness, their love, and the example of Christ who became poor for their sake. He tells them to give as they have purposed, cheerfully. This is giving driven by a transformed heart rather than an audited ledger. It can land above ten percent or, in a season of hardship, honestly below it, because the measure is the heart and the ability, not a flat rule.
"Every man shall give as he is able, according to the blessing of the LORD thy God which he hath given thee."
Deuteronomy 16:17 (KJV)
Notice how even in the Old Testament, alongside the fixed tithe, there is this generous elasticity. Give as you are able, according to the blessing you have received. A gift is a blessing you have received. So while there is no command that says tithe on it, there is a strong current running through the whole Bible that says, when God blesses you through the kindness of another, let some of that blessing flow onward. Both threads agree on the direction of your heart, even if they differ on the arithmetic.
There is one more truth that changes how a cash gift feels in your hands. The person who gave it is real and worthy of your thanks, but they are not ultimately the source. Scripture lifts your eyes higher.
"Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning."
James 1:17 (KJV)
Grandma's hundred dollars came down, in the end, from the Father of lights. She was the glad hand that passed it to you, and He was the Giver behind the giver. When you see the gift that way, giving a portion of it stops feeling like a tax someone is collecting and starts feeling like what it actually is, a small act of worship. You are acknowledging that the blessing came from God, and you are letting a piece of it keep moving toward His purposes. That is not a burden laid on a happy moment. It is the happy moment continuing on to someone else.
Principles are only helpful if they land on the ground. So here is a plain, four step way to think it through the next time cash shows up in a card. It is not a law. It is a tool to help you give cheerfully instead of anxiously.
Walk through those steps and most gifts sort themselves out quickly. A reimbursement is not new gain, so there is nothing to give on. A genuine gift is new blessing, and then the only remaining question is what your heart purposes. If you land on giving, the next practical decision is how much, and that is where a little math helps.
Say you decide, as a settled matter of the heart, that when someone blesses you with a cash gift you will pass along a tenth of it, the same tenth you already give on your income. What does that actually look like across a normal year of gifts? The numbers are small per gift, which is exactly why people wonder if it is worth the bother. Seeing them side by side is clarifying.
The per gift amounts are modest. Ten dollars here, twenty five there. But that is not the point, and it is important not to pretend otherwise. You do not give on a gift because ten percent of a birthday check will change the world by itself. You give because the habit shapes you. It keeps your hands open. It trains your first instinct, when good things come to you, to be gratitude that overflows rather than a grip that tightens. Over years, a person who gives a little on every gift becomes a certain kind of person, and a person who keeps every windfall entirely becomes another kind. The dollars are small. The formation is not.
You can also see the cumulative side if you want to. If your household receives, say, six hundred dollars in assorted cash gifts across a year, a tenth is sixty dollars given onward. Adjust the slider below to your own reality and watch how a simple percentage on gifts you would otherwise barely notice adds up into real generosity over time. Set the growth rate to zero, since this is about giving rather than investing.
A word of caution here, because this is where bad teaching creeps in. None of this is a scheme to get God to give you more. Giving a tenth of your birthday money is not a deposit that returns a larger check. Scripture never promises that generosity makes you richer in dollars, and plenty of deeply faithful, deeply generous believers have lived and died with very little. Giving on a gift is worship and formation, full stop. If anyone tells you that giving on your gifts will make God multiply your money back to you, close the browser tab. That is not the Gospel. It is a sales pitch wearing the Gospel's clothes.
Here is where sincere Christians genuinely differ, and where a little humility keeps the whole thing healthy. Some believers, out of a robust sense that everything they touch belongs to God, will give a portion of every gift, every rebate, and every dollar found in an old coat pocket. Others reserve their giving discipline for their actual income and treat personal gifts as simply the kindness they were meant to be, received with thanks and enjoyed. Both of these people can be sincere, thoughtful, and generous. Neither is disobeying a clear command, because there is no clear command on this exact point to disobey.
So decide what you can do in faith and with a clear conscience, and then extend the same freedom to the person next to you in the pew who decided differently. Do not let a question this small become a wedge. The person who gives on gifts is not more spiritual than the one who does not, and the one who does not is not stingier than the one who does. What matters is that neither of them gives grudgingly, and that both keep soft, open, grateful hearts.
Jesus does hold out a real promise about generosity, though it is not the prosperity promise. It is bigger and stranger than money.
"Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again."
Luke 6:38 (KJV)
Read in context, this is not a guarantee of cash returns. It is a description of the whole open handed life. When you live generously, generosity tends to come back around to you through the community God places you in, and more than that, you become the kind of person who has room to receive it. The measure you use becomes the measure used with you. A person who gives a little off their birthday check is practicing a posture that will show up in far bigger moments, when real sacrifice is asked and real need is in front of them.
So, should you tithe on a cash gift you receive? The most honest answer is this. You are not commanded to, because the tithe was tied to your increase and a personal gift is a category of its own, both in Scripture and in the tax code, where it is not even counted as income to you. But you are warmly invited to, because the whole weight of the Bible leans toward open hands, cheerful giving, and honoring the God who is the real Giver behind every good thing that comes to you.
If you decide to give a portion, pick a percentage you can give gladly, keep it simple, and do it as worship rather than as accounting. If you decide instead to simply receive the gift with thanks and enjoy it, do that without guilt, and let your generosity live in your income and in the moments God brings across your path. Either way, guard the one thing that actually matters, which is a heart that stays soft, grateful, and glad to give. That heart, and not the size of the check in the card, is what God is after.
For the person receiving it, no. Under IRS rules a gift is generally not taxable income to the recipient, and you do not report it on your return. Any gift tax responsibility falls on the giver, and only if they exceed the annual exclusion amount. So the money is fully yours before you decide anything about giving.
The tithe in the Law was tied to your increase, mainly the harvest and the herd, which is closer to income than to a one time present. There is no verse that says tithe on birthday money. What Scripture does teach clearly is generous, cheerful, purposed giving. So giving on a gift is a good and worshipful choice, but it is a freewill choice, not a debt you owe.
Then it may not be new increase at all. If a friend Venmos you back for concert tickets you fronted, that is a reimbursement, not a gift, and there is nothing new to give on. The heart of the question is whether you actually gained something, or whether money you already had is simply returning to you.
You are free to, and you are also free not to. Deuteronomy 16:17 ties giving to the blessing the Lord has given you, according to your ability. A student with almost nothing gives differently than a household with a steady income. Give what you can purpose in your heart to give cheerfully, even if that is a small amount or a gift of time instead.
There is no fixed rule for gifts, so pick a percentage you can give gladly and consistently. Many people who tithe on income simply apply the same ten percent to a gift for the sake of a clear conscience. Others give a smaller flat portion, or round the gift up to a giving number. The exact figure matters less than the willing heart behind it.
