You have looked at your paycheque and wondered whether to tithe on gross or net income. The gross number is one thing. The figure that actually lands in your bank account is often significantly smaller after CRA, CPP, and EI have pulled their share. Somewhere in the back of your mind you have wondered: which of these is the ten percent actually supposed to come from?
It is a fair question. It is also, I think, a question that reveals more than a math problem. The way you sit with this question says something about where you are actually standing when you come to God with your wallet open.
Stay with me here.
I have sat with this question myself, and I have heard it raised in small groups by men who were clearly embarrassed to ask it. There is a specific kind of shame that comes with what feels like a stingy question about something sacred. The man who asks it is not a bad man. He is often the man who is actually trying to get this right, who wants to do it faithfully, who has simply never had anyone explain the theology clearly enough that he could act on it with confidence.
Most of what gets written on this topic is either triumphalist ("tithe on gross and God will bless you even more") or lawyerly ("your CPP contributions go to your future self, so technically..."). Neither approach takes this man seriously. The triumphalist version is usually pushing something. The lawyerly version is usually avoiding something.
The honest answer sits in neither camp. And getting there requires asking a slightly different question first.
Quick Answer: The Bible does not address gross versus net income — those are modern payroll concepts that did not exist in ancient Israel. The first fruits principle in Scripture leans toward giving from the top before expenses, which in practice points toward gross income. But the more important biblical question is not which number you use. It is whether you are giving from a posture of trust and gratitude, or calculating the minimum you can theologically justify.

Should You Tithe on Gross or Net Income? What the Bible Actually Says
The Bible never uses the terms "gross income" or "net income." That distinction is a product of modern payroll structure, a system that did not exist in ancient Israel. So anyone who tells you Scripture gives a definitive answer in either direction is importing a contemporary question into an ancient text.
What the Bible does say is worth examining carefully. Proverbs 3:9 says: "Honor the Lord with your wealth, with the firstfruits of all your crops." The firstfruits principle runs consistently through the Old Testament. You give off the top. Before you calculate your own portion. Before you know whether the rest of the harvest will come in. This is not a rule about percentages. It is a statement about sequencing and trust.
In an agricultural economy, giving firstfruits was not an accounting exercise. It was an act of faith, giving before you knew whether prices would hold, whether the season would finish well, whether the yield would cover expenses. The act of giving first expressed trust in the One who would provide what came after. Apply that to a modern paycheque: the gross is what God provided through your labour. The taxes, CPP, and EI deductions are claims on that provision that settle afterward. The firstfruits principle points toward honouring God with what He gave before those claims are calculated.
That is the biblical case for tithing on gross income. It is the stronger case.

The Honest Argument for Tithing on Net Income
But here's where it gets real. The argument for tithing on net is not simply an attempt to be cheap. It carries genuine theological weight, and it deserves a fair hearing before we dismiss it.
The argument runs like this: you never actually received the gross amount. It went directly to the government before you ever touched it. You cannot give what you did not receive. Your actual material provision, the money God placed in your hands to steward, is the net. CPP contributions, in particular, are not gone. They are your own deferred income, accruing toward your retirement. Tithing on CPP contributions might mean you tithe on that money twice: once now, and again when you draw CPP benefits in retirement.
These are not dishonest observations. They are real. Especially in Canada, where the gap between gross and net income is substantial. A salaried man earning $80,000 CAD gross might take home somewhere around $58,000 to $62,000 after federal and provincial income tax, CPP contributions, and EI premiums, depending on province. That is a meaningful difference. Asking him to give $8,000 versus $5,800 per year is not a trivial question.
I am not going to tell you the net-income argument is dishonest. It is not. But I am going to tell you what I think is actually happening in most of us when we make it.
What Your Heart Is Actually Doing With This Question
Behind every financial question is a deeper question about what we actually trust and what we are actually afraid of. This is where the math stops and the real work begins.
Most men who wrestle with gross versus net are not engaged in careful biblical exegesis over their morning coffee. They are afraid. They are looking at their mortgage, the grocery bill, the daycare costs, the car payment, and the mental math is not working out the way they hoped. Somewhere underneath the theological question is a quiet hope that the right framework will solve the anxiety. If we can find the correct answer, maybe the fear goes away.
Here's what I've learned the hard way: you cannot tithe your way out of fear. You can give on gross and still be terrified about money. You can give on net with a joyful and generous heart. The calculation matters less than what is happening in your chest when you make it.
2 Corinthians 9:7 is quietly devastating here: "Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver." Paul does not answer the gross versus net question. He does not name a percentage. He speaks entirely about the posture from which giving comes.
The word translated "cheerful" in the Greek is hilaros, which is where we get the English word "hilarious." God loves a hilarious giver. Someone who finds genuine delight in the act because the act expresses something true about who they believe God to be. That is not the emotional state of a man calculating the minimum he can justify. It is the state of a man who has been so undone by what he has received that giving feels like a response, not a transaction.
The Gross vs. Net Difference in Canada: What the Numbers Actually Look Like
Because this is a genuinely Canadian question, it is worth making the numbers concrete rather than leaving them abstract.
Consider two approximate scenarios using 2026 figures for an Ontario resident:
Scenario A: $65,000 gross income
After federal and Ontario provincial tax, CPP employee contributions (approximately $3,867 maximum for 2026), and EI premiums (approximately $1,049 for 2026), take-home pay lands roughly in the $47,000 to $49,000 range. Ten percent of gross is $6,500. Ten percent of net is approximately $4,700 to $4,900. The difference is roughly $1,600 to $1,800 per year, or $130 to $150 per month.
Scenario B: $100,000 gross income
Net take-home in Ontario after all deductions lands roughly in the $68,000 to $72,000 range. Ten percent of gross is $10,000. Ten percent of net is approximately $6,800 to $7,200. The difference grows to $2,800 to $3,200 per year.
These are not hypothetical. They represent a real decision for real families. The point is not to tell you which number to use. The point is that this question deserves a straight answer, not a vague appeal to generosity that never grapples with what generosity actually costs.

The Prosperity Gospel Lie Hiding in This Conversation
Now here's what most pastors won't tell you about money: a significant portion of North American tithing theology is not actually theology. It is fundraising dressed in biblical language.
Malachi 3:10 is the most weaponized verse in this entire conversation: "Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this, says the Lord Almighty, and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it." For decades, churches have used this verse to promise that if you tithe on gross, God will return more money to you.
This is the prosperity gospel. It is a specific, identifiable lie, and it has been used to manipulate people into giving beyond their means while platforms and endowments were built.
Read Malachi in its actual context. God is confronting a covenant people who had become faithless in the most basic acts of worship, bringing blind and lame animals to the altar, treating the temple with contempt. The "test" God extends is not a financial investment formula for personal enrichment. It is a call back to covenant fidelity. The blessings described are covenant blessings for the people of Israel as a nation: land that produces, nations that take notice, reproach lifted from a people who had dishonoured God in public. When someone promises you that tithing on gross will grow your bank account, they have turned generosity into a transaction and God into a vending machine. He is not.
A Practical Framework for Canadian Christians
Here is what I actually recommend. Not as law. As wisdom with some Canadian specificity built into it.
If you are a salaried employee with predictable income, tithe on your gross. The firstfruits principle is clear enough, the calculation is straightforward, and the act of giving before you calculate your own needs is precisely the posture of trust the principle is meant to form in you over time.
If you are self-employed, freelance, or on commission, tithe on net profit after genuine business expenses, before personal income tax. This reflects the agricultural model more accurately, where the tithe was on the yield of the harvest after the costs of producing it. A tradesperson who invoices $120,000 CAD but spends $50,000 on materials, tools, and subcontractors has earned $70,000. Tithing on gross revenue in a capital-intensive business would produce a tithe that exceeds actual income in any year with significant costs.

A specific note on CPP: If you tithe on gross now, including your CPP contributions, you are not obligated to tithe again on CPP income when you receive it in retirement. You have already honoured that portion. Consistency in your system matters more than theoretical perfection in the accounting.
What about giving beyond ten percent? Generosity in Scripture is never capped at a tithe. The ten percent figure is a floor, not a ceiling. As your income grows and your margin expands, sit with the question of whether God is calling you to give beyond it. What does your rich life look like, honestly? Generosity can be part of that answer, not competing with it.
The most important thing about your tithing practice is not the precise calculation you land on. It is that you give consistently, give first, give with intention, and grow in generosity over time rather than calcifying at the minimum you decided on in your twenties.

Frequently Asked Questions About Tithing on Gross or Net Income
Does Canada Revenue Agency treat charitable donations differently based on how I calculate my tithe?
The CRA has no opinion on your tithing calculation. What is relevant is that donations to registered Canadian charities qualify for the federal charitable donation tax credit. Donations up to $200 CAD earn a 15% federal credit. Amounts above $200 earn a 29% federal credit, or 33% if your income puts you in the top federal bracket. Provinces add their own credits on top of the federal amount, which makes larger charitable donations meaningfully tax-efficient in Canada. Keep your official donation receipts from your church or charity.
What if I genuinely cannot afford to tithe right now?
This deserves a straight answer rather than guilt wrapped in a proof text. If your household is in financial crisis, carrying high-interest debt, or unable to meet basic needs, give something, even if it is well below ten percent. God is not auditing your percentage during a season of difficulty. 2 Corinthians 8:12 is clear: "For if the willingness is there, the gift is acceptable according to what one has, not according to what one does not have." Build the habit. Increase as your situation stabilizes. The habit of first-fruits generosity matters more than hitting a specific percentage immediately.
Should a self-employed Canadian tithe on revenue or profit?
Profit after genuine business expenses. Revenue is not income. A contractor who bills $150,000 CAD but spends $70,000 on materials, subcontractors, and equipment has earned $80,000. Tithing on gross revenue would produce a tithe that exceeds actual income in years with significant costs. The agricultural model supports profit-after-expenses as the right baseline. Track your business expenses carefully. Tithe on what you actually received.
Final Thoughts
The gross versus net question is worth answering, and I hope this article has done that honestly. Gross income, where practically possible, is the more faithful posture. Net income, given with genuine cheerfulness and intention, is not a sin.
What is harder than the calculation is writing the cheque. Consistently. Year after year. Even when every line item is pushing back.
Most of us have not held back from generosity because we lacked the right theological framework. We have held back because we were afraid. Afraid there would not be enough. Afraid we were already behind. That fear is real and it is human. But it is also, if we look at it honestly, a statement about who we believe is actually in charge of our provision.
Here is one specific thing you can do tonight: pull up your last three months of income. Calculate ten percent of gross. Then calculate ten percent of net. Look at the actual dollar difference. Then ask yourself honestly: is the reason I lean toward net the theological argument, or is it the number?
That question is worth sitting with before you land on an answer. And sitting with it honestly, without self-condemnation, is the kind of heart-level work that moves you toward generosity rather than further from it.
Discussion question: Where in your financial life does the gross versus net question actually feel like a question about trust rather than math? What would it mean for you, practically, to give before you calculate your own needs?
