Should you tithe on gross or net income?

Giving used to be the last line in my budget, whatever was left once everything else had taken its share. Then I learned the tithe is a specific thing, a tenth of your income, and a new question showed up. A tenth of what? Gross pay, or the amount that actually hits the bank?

So let me save you that confusion. The Bible doesn't spell it out. There's no verse that settles gross versus net, which is why sincere, faithful Christians disagree about it. Instead of pretending there's one right answer, I'll walk you through the case for each.

First, what the tithe actually is

A tithe just means a tenth. Scripture pairs it with another gift, firstfruits, which is about giving first and giving your best. Most of us bring the two together, a tenth set aside before anything else. Giving first is the part I used to skip.

Notice it says firstfruits, not leftover fruits. Giving was never meant to be a tax formula. Firstfruits means giving God the first and the best, a way of saying He comes first, before the mortgage and the groceries. Hold onto that idea. It ends up mattering more than the gross-versus-net question itself.

The case for gross (before taxes)

If you tithe on your gross pay, you're giving from everything God provided, before a single deduction touches it. Israel tithed its harvest as it came in. There was no paycheck and no withholding, so the Bible never had to answer this question. For many people, gross feels closest to that picture.

The case for net (after taxes)

Now the other side, and it's a good argument. You never actually received the tax money. It went straight from your employer to the government. You can't give away money that never reached your hands, so you tithe on what you take home. Plenty of faithful, generous Christians give on net for exactly this reason. They give first from the pay that actually reaches them.

So which one should you pick?

This is a matter of conscience, and I mean that as more than a soft dodge. Paul leaves the decision with you.

Paul leaves the decision to your own heart, which makes gross or net a question for prayer. The gift is meant to be cheerful, not cornered out of you by a rule. It would be a shame for the gross-versus-net debate to become the reason you never start. Either base is a fine place to begin, and you can adjust later if your conscience nudges you.

One caution, since we're being honest with each other. Tithing is not a lever you pull to make God pay out. He isn't a vending machine, and anyone who tells you giving guarantees you'll get rich is selling something scripture never promised. We give because He gave first.

A quick way to see the difference

It's the same ten percent either way. What changes is where in your pay it comes out. Watch the gold step move:

That gold step is the whole question. On gross, you count the tenth from your full pay. On net, you count it from what reaches your account. Either way you can set it aside first, and that order is what makes it firstfruits. A tithe on take-home is the smaller amount, and how much smaller is down to your own tax situation. The base your conscience is at peace with is a fine place to begin.
