Ask a Christian who draws a steady paycheck how much to tithe, and the math is almost boring. Ten percent of the number on the pay stub, done. But ask the woman who runs a landscaping company, or the freelance designer, or the couple who own a small bakery, and the same question suddenly grows teeth. Do they tithe on every dollar that lands in the business account, even though most of it flies right back out to pay for mulch, flour, subcontractors, and rent? Or do they tithe on what is left after all of that, the profit? And is the profit even the right number, when half of it got reinvested and the tax form says they owe on money they never took home? These are not dodges. They are honest questions from people who genuinely want to honor God with their first and best. They deserve an honest answer that takes both the Scripture and the math seriously.
“Honour the LORD with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.”
Proverbs 3:9-10 (KJV)
Notice the word the verse leans on. Increase. Not gross receipts. Not everything that touches your hands. Your increase, the first-fruits of it, honored back to God who gave the harvest. That single word does most of the work in answering the revenue versus profit question, and this guide will unfold why. First we will look at the first-fruits principle and why a business is closer to a farm than to a paycheck. Then we will get specific with real numbers, walking a sole proprietor and an LLC owner through what their increase actually is, how pass-through taxes and reinvestment complicate it, and whether to give from the business or personally. Throughout, we will hold the ten percent question with a gentle hand, because sincere believers land in different places, and the heart matters more than the arithmetic.
The tithe did not begin as a tax on total sales. It began in the fields. When God gave Israel the law, He tied the tenth to the yield of the land and the flock.
And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is the LORD's: it is holy unto the LORD. (Leviticus 27:30, KJV)
A farmer did not tithe on every seed he planted. He tithed on the harvest that came up, the increase over what he had sowed. The same logic runs through the command in Deuteronomy, where the people are told to bring the tenth of what the field produced year by year. The picture is always of yield, of gain, of the surplus that the ground gave back beyond what went into it. That is what the Hebrew word behind increase carries. It is not the raw volume that passed through the farm. It is what the farm produced on top of its costs.
Hold that picture next to a modern business and the answer starts to come into focus. Gross revenue is not your harvest. It is closer to the total weight of everything that moved through the barn, including the seed you bought, the fuel you burned, and the wages you paid the hired hands. The harvest, the increase, is what remains after the field has been worked and the costs of working it have been covered. For a business, that is profit. The money that is genuinely yours, the gain God gave you through the venture, is what is left after the true costs of producing the income are paid.
This is why tithing on gross revenue can quietly go wrong for an owner. Suppose a contractor collects one hundred thousand dollars on a job but pays eighty thousand of it to suppliers and subcontractors. Only twenty thousand is his increase. If he tithes on the full hundred thousand, he is giving ten thousand dollars out of a twenty thousand dollar gain, an effective fifty percent of his real harvest, and he is tithing on the eighty thousand that was never his, money that belonged to the lumber yard and the crew all along. That is not more generous. It is a misreading of what increase means. The first-fruits principle asks for the first and best of your gain, offered with a whole heart. It does not ask you to tithe on other people's money as it passes through your account.
The reason the paycheck example feels so clean is that an employer has already done the subtracting for you. By the time wages hit an employee's account, the company has paid for the building, the materials, the equipment, and the overhead. The paycheck is pure increase to the worker. There are no hidden costs still bundled inside it. So tithing on gross wages and tithing on the worker's increase come to nearly the same number, and the question never arises.
A business owner sits on the other side of that line. When money lands in your business account, the subtracting has not happened yet. Buried inside that deposit are the costs you still owe to produce the very thing you sold. You are, in effect, holding both the harvest and the seed and the fuel all at once, undifferentiated, in one bank balance. To find your increase, you have to do the work the employer would have done, separating the gain from the cost of producing it. This is not a loophole. It is simply the honest accounting that a farmer or a merchant always had to do to know what his harvest really was.
Scripture actually honors this kind of counting. Jesus praised the man who sits down before he builds.
For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? (Luke 14:28, KJV)
Counting the cost is not unspiritual. It is wisdom. And knowing the true cost of producing your income is exactly what lets you know your true increase, which is exactly what the first-fruits principle asks you to honor God with. The employee's cost was counted for her by the company. The owner has to count it herself. That is the whole difference, and it is why revenue is almost never the right base for an owner's tithe.
Let us make this concrete with a freelancer, because the sole proprietor is the simplest case and the most common. Meet a self-employed graphic designer. Over the year she invoices clients for ninety thousand dollars. That is her gross revenue, the number that would show up if you added every payment she received. But that number is not her increase. To find her increase, she subtracts the real costs of doing the work.
Say she spends six thousand dollars on design software, contract help, and a portion of her home office and internet, and another four thousand on a new computer and a conference. Her business expenses come to ten thousand dollars. Her net profit is eighty thousand dollars. For a sole proprietor, this net profit is her increase, because she and the business are the same taxpayer and there is no separate paycheck to muddy the picture. A tithe of ten percent on her eighty thousand dollar increase is eight thousand dollars. Had she tithed on the ninety thousand dollar gross instead, she would give nine thousand, an extra thousand dollars levied on money she had already spent to earn the income. Not wrong to give, but not what the first-fruits principle requires, and a real strain in a lean year.
There is one more wrinkle worth naming honestly, and it cuts the other way. The self-employed owe self-employment tax, roughly fifteen point three percent for Social Security and Medicare, on top of income tax, because they pay both the employee and employer halves. That is a real cost of being your own boss, and it comes out of the same increase you are tithing on. Some owners choose to tithe on profit before taxes, giving God the first-fruits ahead of the government, in the spirit of honoring the Lord first. Others tithe on profit after setting aside taxes, reasoning that the tax money was never truly their increase to keep. Scripture does not hand down a rule on this. Both can be offered with a clean conscience. What matters is that you decide on a principle and give cheerfully, not grudgingly.
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)
Now raise the difficulty. Consider a couple who own a small manufacturing LLC that has elected to be taxed as an S corporation. Here the money splits into pieces that a sole proprietor never has to think about, and the pass-through structure creates the hardest tithe question of all.
Their business brings in four hundred thousand dollars in revenue. After all the costs of production, materials, labor, rent, and overhead, the business has a net profit of one hundred thousand dollars. But that hundred thousand does not all land in their pockets. They pay themselves a reasonable salary of sixty thousand dollars during the year. They take another twenty thousand as a distribution. And they deliberately leave twenty thousand inside the business to buy a new machine next year and to build a cash cushion. Here is the sting: because the LLC is a pass-through, they are taxed personally on the full one hundred thousand dollars of profit, including the twenty thousand they never took home. The IRS treats the whole profit as their income whether they drew it out or not.
So what is their increase for the tithe? There are two honest answers, and gracious believers choose between them. The first says increase is increase the moment it is earned, so they tithe on the full one hundred thousand dollars of profit this year, ten thousand dollars, and count the reinvested twenty thousand as already tithed when it later comes out. The second treats the reinvested twenty thousand like seed held back for next year's planting. They tithe this year on the eighty thousand they actually received as salary and distribution, eight thousand dollars, and they tithe on the retained twenty thousand in the year they eventually draw it as income. Both give on every dollar of increase exactly once. Neither double counts, and neither pretends real gain was never gain. The danger to avoid is the third path, where reinvested money is quietly never tithed at all because it was convenient to forget it.
The reinvestment question deserves its own careful look, because it is where sincere owners most often get tangled. Money left in the business to fund growth is genuinely different from money taken home to spend. It is closer to the seed a farmer keeps back from the harvest to plant the next crop. And Scripture does picture the sower setting aside seed, giving to the sower as well as bread to the eater.
Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness. (2 Corinthians 9:10, KJV)
That verse is not a tithing formula, so we will not bend it into one. But the principle it reflects, that some of the harvest is rightly held back as seed for the future, is real and wise. The U.S. Small Business Administration notes that reinvesting profits is one of the most common and healthiest ways small businesses fund their own growth. A machine bought with retained earnings, an inventory build, a cash reserve for a slow season, these are not extravagances. They are the seed that lets next year's harvest exist at all.
The clean way to handle it is to tithe on increase once, on a consistent principle, and to treat retained earnings as either tithed now or tithed when withdrawn, but never as invisible. Write your rule down. If you decide that increase is tithed the year it is earned, then reinvested profit is tithed now, and when you eventually take it out you owe nothing more on those particular dollars. If you decide to tithe on money as you actually receive it, then retained earnings wait and are tithed when they come to you. Either is honest. What corrodes a giving life is not the choice between them. It is quietly changing the rule every year to land on the smallest possible number.
A related question trips up many owners: should the gift come out of the business, or out of your personal account after you have paid yourself? Spiritually, either honors God, because in both cases your increase is being met with generosity. Practically, the answer depends on your entity and is worth a short conversation with a tax professional, because the IRS treats the two differently.
For a sole proprietor, it hardly matters, because you and the business are the same taxpayer on the same return. A gift is a gift, and it lands on your personal Schedule A as a charitable deduction if you itemize, whether the check came from the business account or your household account. For an LLC taxed as a partnership or an S corporation, the profit and often the charitable giving still flow through to your personal return, so the practical effect is similar, though the paperwork differs. A regular C corporation is its own taxpayer and can deduct charitable gifts within limits on its own return. The point is not to master the tax code here. The point is that the choice is a stewardship question, not a spiritual loophole, and the IRS Self-Employed Individuals Tax Center and your accountant can tell you the cleanest path for your structure.
Whatever you choose, keep it clear in the books. Record each gift once, in the right place, so you are neither double counting your generosity nor losing track of it. Clean records are not the opposite of a generous heart. They are what lets a generous heart give steadily, year after year, without confusion or guilt. The bookkeeping serves the giving. It never replaces it.
We have used ten percent all through this guide as a working number, and it is time to be honest that faithful Christians disagree about whether a strict tenth still binds the believer. Some point to Abraham giving a tenth to Melchizedek before the law was ever given, and to the enduring wisdom of a fixed, disciplined baseline, and they hold the tithe as a floor for generosity. Others point out that the tithe belonged to the Mosaic system, and that the New Testament calls for something both freer and often larger, proportional, cheerful, sacrificial giving from a willing heart.
Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gathering when I come. (1 Corinthians 16:2, KJV)
As God hath prospered him. There is the New Testament measure, and notice how naturally it fits the business owner. Giving is proportioned to prosperity, to increase, laid aside regularly and deliberately. Whether you call your ten percent a tithe or simply a proportional starting point, the spirit is the same: give first, give in proportion to how you have been blessed, and give with joy. We will not tell you the tithe is a strict command, and we will not tell you it is abolished. We will tell you that God loves a cheerful giver, that first-fruits means the first and best rather than the leftovers, and that your increase, honestly reckoned, is the harvest you have to work with.
So gather it all up. The tithe was always tied to increase, to the harvest a field gave back beyond its costs, never to the raw volume that passed through the barn. A business owner is a modern farmer in this respect, holding the harvest and the seed and the fuel all in one bank balance, and his first job is to separate the gain from the cost of producing it. For nearly every owner, that makes profit, or the money actually drawn from the business, the honest base for the tithe, not gross revenue, which quietly taxes the same dollars twice. The pass-through owner must reckon with profit he is taxed on but may not have taken home, and the wise path is to tithe on real increase once, consistently, whether earned or drawn, and never to let reinvested gain vanish untithed.
And under all of the arithmetic sits the one thing that matters most. This is not a formula for making your business grow. Giving is not a lever that forces God's hand or guarantees a return. Faithful, generous business owners still endure failed launches, brutal years, and real loss, and the prosperity teaching that says otherwise is a false gospel. What the first-fruits principle offers is something better than a payout. It offers a heart that holds the business with open hands, that honors God with the first and best of the harvest rather than the scraps, and that gives cheerfully whether the year was fat or lean. Reckon your increase honestly. Give of it gladly. Then leave the barns and the presses, the profit and the growth, in the hands of the Lord who gave you the field in the first place.
For almost every owner, profit is the honest answer, because the tithe in Scripture is tied to increase, and your increase is what remains after the costs of producing the income. Gross revenue includes money that was never really yours, such as the cash you paid a supplier for materials or a subcontractor for labor. Tithing on that gross figure can mean giving on the same dollars twice, once as they flow through your business and again when they show up as your personal draw. Tithing on net profit, or on what you actually pay yourself, captures your true increase without double counting.
Sincere believers disagree here, and both sides love God. Many hold that the tithe, a tenth, remains a helpful and Biblical baseline for giving. Others note that the New Testament emphasizes cheerful, proportional, willing giving rather than a fixed percentage, and that the tithe belonged to the law of Moses. A gracious position honors the ten percent as a strong starting point while remembering that the heart, not the arithmetic, is what God weighs. This guide uses ten percent as a working example, not as a rule we impose on your conscience.
This is the classic pass-through squeeze. Your business profit passes through to your personal tax return, so you are taxed on it even if you left much of it in the business to buy equipment or build a cushion. A reasonable approach is to tithe on your real increase for the year, which most owners define as their salary plus any distributions they actually received, and then to tithe on retained profit in the year they eventually draw it out. The goal is to give on your increase once, honestly, without giving twice or pretending money you reinvested was never increase at all.
Either can honor God, and the better choice often depends on your entity type and your accountant's guidance. A sole proprietor and the business are the same taxpayer, so it makes little practical difference. An LLC or corporation is a separate entity, and a gift from the business versus a gift from your personal draw can be treated differently on your return. What matters spiritually is that your increase is met with generosity. What matters practically is that you keep the books clear so a gift is recorded once and in the right place.
Reinvested money is a genuine gray area, and faithful owners land in different places. One view says increase is increase the moment it is earned, so you tithe on profit even if you plow it back into the company. Another view treats reinvested profit like seed kept for next year's planting, and tithes on it when it finally comes to you as income. Neither is dishonest. Pick a consistent principle, write it down, and follow it year to year rather than reinventing the rule whenever the number is inconvenient.
Scripture makes no such promise, and you should be wary of anyone who says it does. Giving is worship and an act of trust, not a deposit that guarantees a business return. The Bible is honest that godly, generous people still face failed ventures, downturns, and loss. What giving offers is a heart loosened from the grip of money and the joy of honoring God with your first and best. That is worth far more than a payout Scripture never offers, and it remains true whether your business booms or struggles.
