Tithing on Investment Gains and Dividends
"'For the love of money is a root of all kinds of evil.'" — 1 Timothy 6:10, NIV
One of the most complex questions believers face regarding tithing: Do I tithe on investment income? If I receive $50,000 in dividend income or capital gains in a given year, is $5,000 (10%) of that due to God and my church?
The question matters increasingly in 2026. More people have stock portfolios, retirement accounts, real estate investments, and side hustles generating passive income. The line between earned income (wages) and unearned income (investment returns) has blurred. Clear guidance is essential.
What Counts as Increase in Scripture?
The Old Testament tithe was defined as a tenth of "increase"—the profit remaining after expenses. For an ancient farmer:
Increase = Harvest - Seed, Labor, Tools, and Losses
A farmer harvesting 100 bushels of wheat doesn't owe a tithe on all 100. She owes it only on the genuine increase. If 30 bushels were seed, 20 went to replanting, and 10 were lost to spoilage, she owes tithe on only 40 bushels of actual increase.
Applied to modern investing, this principle suggests you tithe on genuine increase—profit after the invested capital is accounted for.
The Debate: Three Approaches
Approach 1: Tithe on Total Investment Income (Gross Method)
Some believers argue you should tithe on all investment income: the full dividend, the entire capital gain, interest from bonds, rental income from properties.
Reasoning:
- It's increase. You earned it. It belongs to God first.
- Simplicity. You don't have to calculate cost basis or adjust for the principal invested.
- Consistency with gross income tithing. If you tithe on gross salary, why not gross investment income?
Example: You invest $50,000 in dividend-paying stocks. The stock appreciates to $55,000 and generates $2,000 in dividend income. Under this method, you tithe on the $2,000 gain plus any appreciated value sold, which is $7,000 total increase. Tithe would be $700.
Weakness: It ignores the fact that a portion of the $2,000 is return of invested capital, not genuine increase.
Approach 2: Tithe on Net Investment Income (Net Method)
Other believers distinguish between principal and profit. You tithe only on genuine profit—what you've actually gained beyond what you invested.
Reasoning:
- It mirrors biblical firstfruits. The farmer tithes on harvest minus the seed spent.
- It prevents double-taxing. You already paid taxes on the investment, and taxes take a portion. Tithing on the full amount overtaxes your increase.
- It's more precise. You're giving away a percentage of actual profit, not nominal gain.
Example: You invest $50,000. It grows to $52,000 (a $2,000 gain) and generates $500 in dividend income. Net increase is $2,500. Tithe would be $250.
Strength: It aligns with biblical principle more precisely.
Weakness: It requires more calculation and tracking.
Approach 3: Tithe on After-Tax Investment Income (Tax-Adjusted Method)
The most conservative approach: Tithe only on investment income after taxes are paid.
Reasoning:
- Taxes are a real expense. You didn't actually gain that money; the government claimed it.
- In 2026, federal capital gains tax on long-term gains can be 15-20% (plus state taxes). A $10,000 gain becomes $7,000-8,000 after taxes.
- You shouldn't tithe on money the government is taking.
Example: You realize a $10,000 capital gain. After federal and state taxes, you net $7,500. Tithe on that: $750.
Strength: It's realistic about your actual available funds.
Weakness: It might be overly conservative. The tithe obligation existed before the gain was taxed.
A Comparison Table
| Scenario | Gross Method | Net Method | After-Tax Method |
|---|---|---|---|
| $10,000 dividend income | Tithe $1,000 | Tithe $500 (after expense) | Tithe $700 (after 30% tax) |
| $25,000 capital gain | Tithe $2,500 | Tithe $2,500 (all gain) | Tithe $1,700 (after 30% tax) |
| $50,000 rental income, $15,000 expenses | Tithe $5,000 | Tithe $3,500 (net) | Tithe $2,450 (net after tax) |
| $100,000 inherited stock (no gain yet) | Tithe $0 | Tithe $0 | Tithe $0 |
What the Bible Actually Supports
Scripture offers guidance, though not explicit rules for modern investing:
Proverbs 3:9-10 calls for firstfruits of "crops"—increase that represents genuine profit after inputs. This supports the net or after-tax method more than gross.
Malachi 3:10 describes tithing "the whole tithe into the storehouse." The word "whole" suggests the complete increase, not a portion eaten by taxes.
1 Corinthians 16:2 instructs believers to set aside funds "in keeping with income." This implies the funds you actually have available, not theoretical gross figures.
The most biblically consistent approach seems to be: Tithe on net investment income (actual profit after the principal invested is accounted for), or adjust downward for taxes if paying significant tax burden on that income.
Practical Recommendations by Situation
Situation 1: Dividend income from stocks you hold long-term
You invest $100,000 and receive $3,000 annual dividends. You should tithe on the $3,000 (or $2,400 if accounting for the 20% federal tax rate on dividends). The original $100,000 was likely tithed on when it was earned as wages. The dividend is genuine new increase.
Situation 2: Capital gain from selling appreciated investment
You sell stock purchased for $40,000, now worth $60,000. Gain is $20,000. Tithe $2,000 (or $1,400 after capital gains tax). You're not tithing on the original $40,000 (already tithed as wages). You're tithing on the actual gain.
Situation 3: Rental property with net income
Your rental property generates $30,000 in revenue and costs $15,000 in expenses (mortgage interest, property tax, insurance, maintenance, vacancy). Net increase is $15,000. Tithe $1,500 (or $1,050 after taxes). The net reflects actual increase, not gross revenue.
Situation 4: Small inheritance or gift (non-income)
You inherit $50,000 from an aunt. This is not investment increase; it's a transfer of principal. Most believers would not tithe on this. See the separate article on tithing inheritances.
Situation 5: Cryptocurrency or volatile investment gains
You invest $10,000 in Bitcoin. It's worth $35,000. Do you tithe on $25,000 gain? Not yet, arguably. Tithe when you sell (realize) the gain. Until then, it's unrealized appreciation, not actual increase available to tithe.
The Consistency Question: How to Treat Different Income Types
If you tithe on earned wages (salary), you should probably tithe on investment income consistently:
| Income Type | Approach | Tithe Calculation |
|---|---|---|
| W-2 Salary | Gross or net, consistently chosen | ~10% of your decided base |
| Self-employment income | Gross revenue less business expenses = net profit | 10% of net profit |
| Dividend income | Net of original investment | 10% of dividend received |
| Capital gains | Net of original purchase price | 10% of realized gain |
| Interest income | Gross (it's pure income) | 10% of interest received |
| Rental income | Net of expenses | 10% of net after operating expenses |
| Inheritance | Generally not tithed | $0 |
| Gifts | Depends on intent; usually not tithed | $0-10% based on conscience |
A Practical Case Study: Jennifer's Investment Income
Jennifer earns $90,000/year (salary) and tithed $9,000 annually. In 2026, she experiences:
- $4,000 dividend income from $100,000 in dividend-paying stocks
- $12,000 capital gain from selling appreciated mutual funds
- $600 in interest from savings
Should she tithe on all $16,600 in investment income?
Honest analysis:
- The dividends ($4,000) are genuine increase. Her stock was purchased from after-tax wages (already tithed on). The dividends are new money. Tithe: $400.
- The capital gain ($12,000) exceeds the dividend, but she'll pay capital gains tax. After 15% federal + 3% state tax (~18%), she nets $9,840. Tithe on net: $984.
- The interest ($600) is pure income. Tithe: $60.
Jennifer's total additional tithe on investment income: $1,444.
This feels more aligned with biblical principle than tithing $1,660 (10% of all investment income) while paying significant taxes.
The Heart Question
Ultimately, tithing on investment income reveals your deeper convictions about wealth. Do you see investment returns as genuinely "yours," or as part of God's provision you manage? Are you trying to maximize giving, or minimize giving while appearing generous?
Proverbs 11:24-25 states: "One person gives freely, yet gains even more; another withholds unduly, but comes to poverty. A generous person will prosper; whoever refreshes others will be refreshed."
The principle isn't about hitting a percentage. It's about a generous heart that acknowledges all increase comes from God. Some believers tithe on gross investment income out of abundance and conviction. Others tithe on net income with equal sincerity. Both can be righteous approaches.
