Should I Tithe on My Gross or Net Income?

Today we’re tackling a question that many Christians have debated for years: should you tithe on your gross or your net income?

On the surface, it sounds like a technical financial question. But underneath it reveals something deeper about the heart.

Are we trying to faithfully honor God with our giving, or are we trying to determine the minimum amount we can give and still feel comfortable?

Jesus often warned about reducing obedience to careful calculations while missing the weightier matters of the heart. So in this episode, we’ll walk through both sides of the argument…but more importantly, we’ll re-center the conversation on gratitude, worship, and responding to the God who first gave to us.

 

What Do We Mean by Gross vs Net?

Before diving in, it helps to define the terms clearly:

  • Gross income is your total earnings before taxes, deductions, or expenses.
  • Net income is what remains after those deductions, the amount that actually hits your bank account.

A simple way to remember it:

  • Gross = it’s gross how much gets taken before you see it!
  • Net = what’s left in the net after dragging it through the ocean.

 

Why Are We Really Asking This Question?

At its core, this question often reveals a deeper tension:

Are we trying to figure out the minimum God would “accept”?

When giving becomes primarily about precision and technical boundaries, we risk drifting into the same mindset Jesus confronted in the Pharisees. They were meticulous…tithing even their spices like mint, dill, and cumin. Yet they missed justice, mercy, and faithfulness.

The issue isn’t that details don’t matter. It’s that obsession with the details can distract from the heart of obedience.

Gross vs net is not a meaningless question, but it becomes dangerous when it replaces the bigger question: Am I honoring God with what He has given me?

 

Arguments for Tithing on Gross Income

Those who advocate for tithing on gross income typically emphasize the following:

1. “Bring the Full Tithe”

Scripture repeatedly frames the tithe as the “full” portion offered to God. From this perspective, anything less begins to feel like a reduced offering rather than a faithful one.

2. Giving From Your Increase

Supporters argue that “increase” in a modern economy is best understood as total earnings before deductions. Taxes, retirement contributions, and insurance are not seen as separate from income, they are simply obligations within that income.

3. Avoiding Selective Accounting

One concern raised is that if we begin subtracting categories (taxes, benefits, retirement), it becomes easy to continually shrink the base of what we consider “income,” potentially reducing generosity over time.

A Common Counter-Argument

Some argue you don’t need to tithe on retirement contributions now because you’ll tithe on them later when withdrawn. However, critics note that this reasoning can become circular, especially as investment growth and compound interest complicate what is considered “increase.”

 

Arguments for Tithing on Net Income

Others believe net income is the more faithful baseline:

1. You Don’t Actually Control Gross Income

Net income reflects what you actually receive and can steward. Taxes and deductions never reach your hands, so they are not practically available for giving decisions.

2. Retirement Contributions Are Future Income

From this perspective, retirement savings represent deferred income. You would give on it when it is eventually received, rather than when it is initially set aside.

3. Avoiding Overcomplication

Some simply conclude that trying to parse every category of income leads to unnecessary complexity. In practice, it can become a “math game” that distracts from generosity.

 

The Real Issue: Are We Playing Accounting Games?

It’s easy to get caught up in technicalities that help us feel justified in whatever amount we were already planning to give.

But when giving becomes primarily about financial precision rather than worship, something important gets lost.

This is why the question can feel so frustrating. It risks turning generosity into arithmetic instead of gratitude.

Personally, one way to avoid getting stuck in that mindset is to give beyond the tithe altogether. When generosity moves beyond calculation, the gross vs net debate loses much of its power.

That said, for those who want a more defined answer, there is reasonable biblical support for using gross income as the baseline. But even then, the focus should never be the percentage alone.

 

Closing Reflection: Why Do We Give?

At the center of this conversation is not a tax formula, but a theological reality:

God is a giver.

“For God so loved the world, that he gave…” – John 3:16

Our generosity is ultimately a response to His generosity. We give because we have first been given grace.

And as Jesus said:

“Give, and it will be given to you…” – Luke 6:38

We cannot outgive God.

So whether someone lands on gross or net, the deeper invitation remains the same: give with gratitude, give with joy, and give in response to the God who has already given everything.
