Tithing and Giving: The Two Questions Nobody Settles, and the Arithmetic Anybody Can

Does the tithe bind Christians today?

The disagreement everything else sits on, argued in good faith on both sides.

The case that it does not bind. The tithe is legislated in the Mosaic law (Leviticus 27:30–33, NIV: "A tithe of everything from the land… belongs to the LORD") and funded a priestly tribe holding no land (Numbers 18:21). When the covenant structure it served was fulfilled, the argument runs, the ordinance went with it. Paul, writing to Gentile churches never under that law, names no percentage: he asks for giving "not reluctantly or under compulsion" (2 Corinthians 9:7, NIV) and for weekly setting-aside "in keeping with your income" (1 Corinthians 16:2, NIV) — proportion without a figure.

The case that it does. Abraham gives a tenth to Melchizedek in Genesis 14:20 and Jacob vows one in Genesis 28:22, both before Sinai — evidence, on this reading, that the tenth is a pattern the law codified rather than invented. Jesus names tithing in Matthew 23:23, and although the verse is a woe rather than an endorsement — "Woe to you… you hypocrites!" (NIV) — it closes with "without neglecting the former," taken here as leaving the practice standing.

The traditional ten percent is a baseline many traditions treat as binding and others as a pre-Christian pattern kept voluntarily. Where you land is a question of conviction, and this page has no vote in it.

What Malachi 3:10 says, and what it is asked to say

"Bring the whole tithe into the storehouse, that there may be food in my house" (Malachi 3:10, NIV; the NRSV has "full tithe"). The verse continues with an invitation to "test me in this" and a promise of blessing beyond room to store it.

The context is usually dropped. Malachi addresses a post-exilic community in Judah accused of withholding tithes and offerings (3:8). The storehouse is the temple treasury, the "food in my house" is agricultural produce, and the promise concerns harvest in a covenant nation's land. How far that transfers to a household's bank balance is genuinely disputed, and reading it as a promise that giving returns money is a claim this site does not make.

The verse is also asked to settle something it never touches. One reading holds "full" proves the tithe comes from income before tax; another holds "whole" proves it comes from income after tax. Same word, opposite conclusions — which is the tell. The adjective attaches to the tithe, not to the income it is drawn from: in a dispute about people bringing part of what they owed, it means the whole tithe rather than a partial one. Pressed into the gross-versus-net question it is not exegesis but a modern category read backwards into a text with no pre-tax and post-tax to distinguish.

Before tax or after tax? What each side actually argues

For pay before tax. All income is God's first claim, and taxes are an obligation to a separate authority — "Give to Caesar what is Caesar's, and to God what is God's" (Matthew 22:21, NIV). Israelites owed both a tithe and imperial taxation from the same harvest, so the two were never alternatives. And a percentage of take-home is a smaller real proportion: ten percent of net on $90,000 is about 8.5% of gross.

For take-home pay. Withheld tax is money you never controlled and cannot allocate; households with high effective rates, dependents or medical costs are being asked to give from a number that never reached them. A smaller figure given consistently for thirty years is not obviously worse stewardship than a larger one abandoned in month four.

The middle position. Many households use a modified base — income less the deductions that are genuinely involuntary.

No verdict here, only a price. On $90,000 filing jointly with no state income tax, ten percent of the larger number is $9,000 and of the smaller $7,668 — a gap of $1,333 a year. Set the basis either way in Giving Plan and every downstream figure moves with it.

How to work out the figure, on either basis

Take-home is the number most people cannot state, so derive it. On $90,000 filing jointly with no state income tax, taxable income is $90,000 less the 2026 joint standard deduction of $32,200, or $57,800, on which federal income tax is $6,440. Payroll tax is 6.2% for Social Security plus 1.45% for Medicare, or $6,885. Take-home lands at $76,675 — about $6,390 a month.

Ten percent of $90,000 is $9,000 a year, $750 a month; ten percent of $76,675 is $7,668, or $639. The practical test is what the monthly figure leaves: after $750 of giving and $400 of debt payments, $5,240 — 18% of take-home committed.

Ten percent is a starting point some traditions treat as a floor, some as a ceiling, some as neither. It is one widely used number among several, not the foundation of Christian giving, and this page has no view on yours.

Firstfruits is about order, not about which number you multiply

"Honor the LORD with your wealth, with the firstfruits of all your crops" (Proverbs 3:9, NIV). In Deuteronomy 26:1–11 the farmer brings the first-ripened produce to the priest. The point of the ceremony is sequence: the claim is acknowledged before the harvest is consumed.

That maps onto a paycheck — a standing transfer on payday, before the money is available to spend. What it does not do is decide the gross-versus-net question, though it is constantly recruited to. Firstfruits is about when the gift comes; the basis question is about which number the percentage multiplies. Treating the first as an answer to the second is where much of the confusion here starts.

Self-employed and 1099: three defensible bases

A consultant billing $150,000 with $40,000 of business costs and $25,000 of income and self-employment tax has three plausible bases, $65,000 apart end to end.

• Gross revenue — $150,000, giving $15,000, which for many low-margin practices exceeds the owner's profit.
• Gross profit, before personal tax — $110,000, giving $11,000. Common and defensible; not the scriptural one, because there is no scriptural one.
• Available income, after personal and self-employment tax — $85,000, giving $8,500.

Nothing adjudicates between these, because none existed as a category in the source economy. Self-employment tax runs about 15.3% on net earnings, which is why the third base is not stinginess. Check your figures with the self-employment tax calculator first.

Business owners: revenue, profit, or your own draw?

The case against gross revenue is arithmetic, not theological: a business grossing $500,000 with $450,000 of legitimate costs has $50,000 of profit, so ten percent of revenue is the whole of it.

Between net profit and the amount actually drawn the question is genuinely contested, turning on whether reinvested profit counts as increase you received. An owner netting $80,000 who reinvests $20,000 might reasonably give on $80,000 or on $60,000. The profit base is a widely held reading of "increase"; scripture does not legislate between profit and draw, and honest accounting matters more than which you pick.

Rental and side-hustle income: where the base choice costs most

Landlords show the problem at its sharpest. A property collects $24,000 of rent against $8,000 of mortgage principal, $6,000 of interest, $3,000 of property tax, $2,000 of insurance, $1,500 of maintenance, $1,500 of vacancy and $1,200 of management: net cash flow $800.

Ten percent of $24,000 is $2,400 — three times the cash the property produces. Ten percent of $800 is $80. So far, obvious. But a third figure is rarely named: mortgage principal is not an expense, it is equity you now own. Add it back and economic profit is $8,800, so ten percent is $880. Eleven times the cash-flow answer, same property, same year, no theology involved. Both bases are defensible, and the gap dwarfs anything gross-versus-net produces.

Gig work has the same problem in vehicle cost. The IRS business standard mileage rate changed mid-year in 2026: $0.725 a mile for 1 January to 30 June, $0.76 from 1 July — so "the 2026 rate" is not one number, and a mileage log needs dates. The separate charitable rate is fixed by statute at 14 cents.

Dividends, capital gains, and money you have not received yet

Three distinctions do most of the work, and none is contested.

Realised versus unrealised. A holding that has doubled has produced nothing you can give until you sell; a paper gain is not income in any accounting sense.

Return of capital versus increase. Stock bought for $40,000 and now worth $60,000 produces $20,000 of increase, not $60,000.

Before or after the tax on the gain. Long-term gains and qualified dividends are taxed federally at 0%, 15% or 20% depending on income, plus state tax. Giving on the pre-tax or post-tax gain is the gross-versus-net argument in a different suit, unsettled here too.

One clean mechanic for anyone who itemizes: giving shares held more than a year, rather than selling and giving cash, means the tax on the gain is never triggered. The gift is not made cheaper — the tax simply never arises. Appreciated property has its own ceiling, 30% of income rather than 60%.

A refund and a bonus are not the same kind of money

A tax refund is over-withholding coming back: money already part of the year's income, already counted in whatever base you use, so treating it as fresh income counts the same dollars twice. A bonus is different — compensation that did not exist before and appeared in no prior calculation.

This is the one windfall question with a clean answer, because it is an accounting question rather than a theological one. Whether you also give from a refund is a separate, free decision.

Gifts and inheritances

Three positions, each with a real argument. No: the tithe attaches to increase — harvest, herds, yield — and an inheritance is a transfer of principal, most likely already given on by whoever accumulated it. Yes: it increases your net worth, and a line drawn at how the money arrived can look like a distinction of convenience. Give, but not as a tithe: no percentage is owed, and a freely chosen gift is gratitude rather than the discharge of an obligation.

Saying the tithe is commanded on earnings but not on transfers asserts two contested things at once: that it binds, and exactly where its edge falls. Neither is settled. Inherited retirement accounts sit awkwardly across all three, because withdrawals are taxable income to you even though the account is inherited principal.

Social Security and pensions

A pension is deferred wages, and most people treat it like the salary it replaced. Social Security is harder, being partly a return of what you paid in through payroll tax over a career and partly a transfer funded by current workers. Three approaches are in use. Give on all of it, since it is income arriving monthly that you control. Give on none of it, since you already gave on the wages that funded it. Or give on the portion exceeding what you contributed — precise in principle, close to uncomputable in practice, since it depends on how long you live.

Giving on a fixed income, without pretending the maths has not changed

Retirement removes the variable that made rising giving painless: raises. A household that gave $1,100 a month on peak earnings and gives $600 in retirement has not backslid; its income fell. Three moves change the arithmetic rather than the resolve:

• From age 70½, give straight from an IRA. A qualified charitable distribution goes from account to charity without entering your income — worth more than a deduction near an income cliff, because Medicare surcharges, the investment-income surtax and the taxation of Social Security are all measured against income a deduction cannot undo. It counts toward a required withdrawal, and must go directly: withdraw first and the exclusion is lost. There is an annual limit; confirm it against IRS Publication 590-B.
• Give appreciated shares rather than cash, for the reason above.
• Name charities in the will — it costs nothing during a retirement of uncertain length.

The retirement calculator and RMD calculator will tell you what the income actually is before you set a figure.

Giving while carrying debt — and the number both sides ignore

Two positions, both held seriously, usually stated as conclusions. Give through it: giving is a practice, not a residual, and "until the debt is gone" is a promise easily deferred for a decade. Clear the debt first: compounding interest grows while you deliberate, and a household paying 29% on a card loses ground faster than any budget line can recover.

Here is what almost nobody prices. Take the $9,000-a-year gift from the running example. One year of interest on money that size:

Nearly ten times, across the range, for advice that does not change. Set against that, the federal tax the same gift saves this household is $240. Guidance that does not distinguish a 3% mortgage from a 29% card is not neutral between the two positions — it is silent on the thing that decides how much the question costs.

Giving Plan prices it directly: its debt-tension result puts one year of interest at your rate beside the tax the gift saves, and stops. It does not say which should win. Pair it with the debt payoff planner for the timeline under each choice.

Tithing and the charitable deduction are different things — and 2026 changed the second

A tithe is a religious practice; a deduction is a line on a tax return. Confusing them produces the commonest error here: treating the tax saving as though it offsets the gift. It never does. A deduction lowers the income you are taxed on and returns your tax rate on the deductible part — always strictly less than the gift.

2026 changed the answer in both directions at once, and almost nothing published has caught up:

• If you itemize, you lost the first slice. Only contributions above 0.5% of adjusted gross income are deductible at all. On $200,000 of income the first $1,000 of giving does nothing.
• If you take the standard deduction — roughly nine in ten filers — you gained a deduction for the first time since 2021. Up to $1,000 filing single, $2,000 jointly, for cash gifts. It is permanent, and larger than the lapsed 2020–2021 provision people confuse it with.

Run the household from earlier. Itemizing gives $9,000 less the $450 floor, or $8,550. The standard path gives $32,200 plus the $2,000 non-itemizer amount, or $34,200 — winning by more than $25,000. The deduction the gift buys is $2,000, taxed at 12%, so federal tax falls by $240 and the $9,000 gift costs $8,760: about 97 cents on the dollar. Anyone still computing "gift × marginal rate" gets $1,080, four and a half times too high. Giving Plan runs both paths and reports which one your numbers land on.

Two more figures: cash gifts to public charities are deductible up to 60% of income in a year, excess carried forward five years; and the 100%-of-income figure still circulating lapsed after 2021. Every number here comes from functions/_lib/tax-constants.ts, sourced to Pub. 526 and Topic no. 506, verified 31 July 2026.

Putting it in the budget, before it becomes a remainder

What decides how much most households give is not conviction; it is ordering. Money allocated at the end of the month competes with everything that already happened. Money allocated on payday does not.

Work out take-home (the take-home pay calculator will do it), subtract genuine fixed costs, and set the giving figure from what remains rather than from a percentage you read somewhere. Keep it in its own account so it is visibly not spendable. One caution: planning does raise giving, but the multiples this literature quotes are invented — treat the mechanism as real and the statistics as decoration.

Automating it, and the one thing automation does not fix

A standing transfer on payday removes three failure modes: forgetting, deciding again every month, and the spiral where three missed months turn a gift into a felt debt. Bank transfer, the charity's recurring form and ACH all work; a card adds fees the charity pays.

What automation does not fix is whether the amount was right to begin with: a figure that was uncomfortable in January is still uncomfortable in December, only now it is invisible. Review it annually, and automate the mechanism rather than the decision.

"Cheerful" is a diagnosis, not a demand

"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" (2 Corinthians 9:7, NIV). Paul is writing about a collection for the Jerusalem church, and the two negatives carry as much weight as the adjective.

Read as a demand the verse becomes another obligation — now you must give, and feel a particular way about it. Read as a diagnosis it is more useful: persistent resentment about a giving level usually means the figure exceeds what the budget holds, or the recipient is not trusted, or the giving is settling a score that giving cannot settle. Each has a different fix, and only the first is arithmetic.

Comfortable giving, sacrificial giving, and dangerous giving

$500 a month is 3.3% of a $180,000 income and 12.5% of a $48,000 one: one requires nothing, the other requires rearranging a life.

Three bands are worth naming. Comfortable giving comes from genuine surplus and changes nothing. Sacrificial giving requires real trade-offs, chosen deliberately and sustained for years. Dangerous giving undermines necessities: rent, food, insurance, medication, minimum debt payments. That third band is not an advanced version of the second; it is a different thing, and it is where the widow's-mite passage gets misused.

Which of the first two you choose is yours. Where the line to the third sits is arithmetic: above roughly a quarter of take-home committed to gift plus debt payments, a plan is tight.

The widow's mite is not an instruction to give your rent money

"This poor widow has put in more than all the others… she out of her poverty put in all she had to live on" (Mark 12:43–44, NIV). The passage is regularly used to press people past their necessities, and that reading does not survive its own context.

Immediately before it, Jesus condemns teachers of the law who "devour widows' houses" (Mark 12:40, NIV); immediately after, he foretells the destruction of the temple the disciples are admiring (13:1–2). The two coins are framed by an indictment of the institution receiving them. What the passage says plainly is that proportion and cost are what register, not the absolute figure — which cuts in favour of small givers, not against them.

Offerings and alms: the categories the percentage conversation misses

In Israel's practice the tithe and the offerings were different instruments: the tithe fixed and ongoing, the burnt, grain and fellowship offerings brought as people chose. The New Testament does something similar with different vocabulary — almsgiving to the poor (Luke 12:33), a collection for a famine-struck church (Romans 15:25–27), support for teachers (Galatians 6:6) and travelling workers (3 John 5–8). None of it framed as a percentage.

The distinction separates the regular commitment from the responsive one. A household with a standing transfer and nothing set aside for the unexpected — a disaster appeal, a friend in trouble — ends up raiding the regular gift or giving nothing. A small sinking fund fixes that.

Time and talent count — and they do not pay the electricity bill

Money, hours and skill are all real generosity, and someone who gives fifteen hours a week and little cash is not less generous than a donor who writes a cheque and never appears. Much of the guilt here falls on people whose constraint is cash rather than commitment.

Two cautions on the arithmetic. Converting volunteer hours to dollars at your professional rate and adding them to your giving percentage produces a number meaningful to nobody but you; a charity cannot pay a salary with donated hours. And the substitution does not run both ways: an organisation short of volunteers can sometimes hire, but one short of cash cannot convert time into rent.

Anonymous giving, recognition, and the tax receipt

"When you give to the needy, do not let your left hand know what your right hand is doing" (Matthew 6:3, NIV). The passage sits in a series — giving, prayer, fasting — contrasting practices done "to be seen by others" with the same done in secret. The target is a divided motive, not publicity as such.

That resolves the two questions people actually have. Does claiming a deduction violate it? The deduction is a mechanism the tax code supplies, not the reason for the gift; if it becomes the reason, that is the thing to examine. Does giving where your church knows violate it? Not by itself — the passage names the motive, not the ledger. The test is the counterfactual: if nobody would ever know, would you still give, and at that size? Most charities accept anonymous gifts, and donor-advised funds can grant anonymously while still generating the donor's receipt.

Where should it go?

"Storehouse" in Malachi is a specific building: the temple treasury of a nation with one temple and one priesthood. There is no modern equivalent, which is why the question is contested rather than obvious.

The local-congregation reading. Your congregation is the one feeding you, the one whose accounts you can inspect, and the one that cannot run on special appeals.

The broader-kingdom reading. The apostolic letters never direct a tithe into a local congregation; they show giving to the poor, to famine relief, to teachers and to travelling workers. On this reading any body gathering and distributing resources for the same ends qualifies, and a household might split its giving across several.

Both are held in good faith. Two notes belonging to neither side: ask for the budget, and read a US charity's Form 990, which is public, before committing.

Planned giving: the instruments, and who each is actually for

Most only make sense above a certain asset level, and the literature rarely says so.

• Donor-advised fund. Contribute now, deduct now, grant over years. The real use is timing: two years of gifts in one calendar year takes the 0.5% floor once instead of twice and can push a single year over the standard deduction, without the charity living through feast and famine. Minimums to open are usually modest.
• Named endowment. Only the investment return is spent, so the gift funds something indefinitely. Typically a five- or six-figure minimum.
• Charitable remainder trust. Income to you, remainder to charity; the point is diversifying a concentrated, highly appreciated holding without triggering the gain. Real legal cost — this needs professionals.
• Charitable lead trust. The mirror image: income to charity first, remainder to heirs. An estate-planning instrument, not a giving one.
• A bequest in the will. Costs nothing now, adjustable any time, available to everyone — for most households the only one here that will ever apply.

Teaching children to give

What works is participation rather than instruction: letting a child give something themselves, pick the recipient within reason, and see what happened afterwards. Splitting pocket money three ways — spend, save, give — teaches proportion before the amounts are big enough to argue about.

Two tensions the parenting advice elides. A mandated percentage of an allowance and a lesson about freely chosen generosity pull against each other; prescribing 20% while calling it voluntary teaches least of all. And children read behaviour, not policy: a household that talks about generosity and never visibly does anything has taught the more memorable lesson.

FAQ

Is the tithe on gross or net income?

Genuinely disputed, and this page does not pick. The before-tax case is that taxes are a separate obligation and a percentage of gross is the honest proportion; the after-tax case is that withheld tax is money you never controlled. The Malachi "full/whole tithe" argument settles nothing, because that adjective describes the tithe rather than the income behind it. The price can be settled: on $90,000 filing jointly the answers are $9,000 and $7,668, $1,333 apart.

Should I give while I am paying off debt?

Both positions are held seriously, and the variable that decides how much the question costs — the interest rate — is usually left out. One year of interest on $9,000 of debt is $270 at a 3% mortgage rate and $2,610 at 29% on a card: nearly ten times, for guidance that does not change. Get your own two numbers — the interest and the tax saved — and decide with them in front of you.

Does giving lower my 2026 federal tax bill?

Sometimes, by less than people expect. If you itemize, only the portion above 0.5% of your income counts — new for 2026. If you take the standard deduction, you can now deduct up to $1,000 single or $2,000 jointly of cash gifts, impossible in 2022–2025. Either way it is a deduction, not a refund, and always smaller than the gift: the worked example saves $240 on a $9,000 gift, not the $1,080 the "gift × marginal rate" shortcut produces. Figures from IRS Pub. 526 and Topic no. 506.

Does giving make you better off financially?

No, and nothing here will suggest otherwise. Giving reduces the money available to you; the tax treatment lowers the cost without reversing it. Malachi 3:10's promise of overflowing blessing is addressed to a covenant nation about its harvest, and reading it as a personal financial return is a claim much of the Christian tradition rejects and this site does not make. Faithful givers do sometimes end up with less.
