Your big tax refund is a loan you made to the government for free

Let me describe a banking arrangement and you tell me whether you would sign up. You give the bank a little money every two weeks. The bank does not pay you interest. It does not tell you how much it is holding. At the end of the year it gives you back whatever it feels like giving back, and it expects you to throw a party. Oh, and you are not allowed to ask for any of it early.

You would run from that bank. Yet tens of millions of American households sign up for exactly that deal every year, and then they call it good news. "I got a big refund!" they say, and the neighbors nod, and somebody on television points at a chart of average refunds as if it measured how much the government loves us.

I want to take the party hats off. A large refund is not a windfall. It is the sound of a year-long, interest-free loan being repaid, and you were the lender. The Treasury borrowed your money at zero percent. Folks, if a private lender did that to you, we would call it something unkind.

This is not a complaint about the IRS, whose employees mostly just follow the law as written. It is a complaint about a habit, and about a system that makes the habit feel like a gift. Let me explain how we got here, how the paperwork controls it, the best argument for keeping things the way they are, and what you can do about it before the next paycheck.

How withholding began

For most of American history, the income tax, when there was one, was paid after the fact. The modern income tax dates from the Sixteenth Amendment in 1913. For roughly three decades after that, an American figured his tax on the previous year's income and paid it in a lump sum or in installments after the year ended. Rates were low and few families paid at all. Then came the Second World War.

The war changed who paid. Income tax stopped being a levy on the well-off and became a levy on the working population, because the government needed enormous sums and the only place to find them was in ordinary paychecks. Through the early 1940s, Congress widened the base and raised the rates. That created a practical problem. A worker who owed a big bill the following March might not have the cash on hand, and the Treasury, with a war to finance, did not want to wait.

Enter Beardsley Ruml, who was then the chairman of the Federal Reserve Bank of New York. In 1942 he promoted a plan that became known as the Ruml plan. The idea was pay-as-you-go: collect the tax from each paycheck as it was earned, so that the money flowed to the Treasury all year. The politics were tricky, because moving to current payment meant that in the changeover year a taxpayer might owe two years' worth of tax at once, the old year and the new. The Ruml plan answered that by forgiving a large share of one year's liability. Critics screamed that this was a giveaway. Supporters said the war could not wait.

Congress passed the Current Tax Payment Act of 1943, and the President signed it in June of that year. Withholding on wages became the law of the land. I want to be careful about the part I am certain of: withholding at the source was introduced in 1943 and has been with us ever since. Whatever the details of the transition, the principle was set. The Treasury would collect as the money was earned.

Here is the conservative observation about that history. It was a wartime measure, adopted for a wartime reason, and it was not repealed when the war ended. That is how a great many federal conveniences, if you want to call them that, have gotten into the system. The tool is so useful to the government that nobody in government has any reason to give it up. And it has a side effect nobody planned for: the taxpayer stopped seeing the tax. The money vanishes before you hold it, and the bill arrives as a number on a pay stub rather than as a check you write. People who never write the check never feel the weight of it.

How the W-4 controls the whole thing

Every new employee fills out the Form W-4, Employee's Withholding Certificate. It is the document that tells your employer how much federal income tax to hold back from each paycheck. The IRS redesigned the form for 2020. The old version had you claim "allowances," which many people did not understand; the new version asks about your filing status, whether you have multiple jobs or a working spouse, credits for dependents, and other adjustments.

The point is that you control the amount. Your employer withholds based on what you tell it, using IRS tables. If you ask for more to be withheld, more is withheld. If you ask for less, less is. Nothing about this is fixed. The government's tax is determined when you file your return, and the withholding is just your advance payment toward it. Everything above the tax you actually owe comes back to you as a refund. Everything below it you owe as a balance due.

So a large refund tells you one thing: the withholding was set higher than the tax. Some people do this on purpose. A lot more do it by accident, because they filled out a form years ago, had a child, changed jobs, or got married, and never touched the form again. The IRS offers a Tax Withholding Estimator on its website for exactly this purpose, and IRS Publication 505, Tax Withholding and Estimated Tax, explains the mechanics. Neither is hard.

The arithmetic of a $3,000 refund

Now the part that I think should make you sit up. Take a hypothetical household that gets a $3,000 refund.

Spread $3,000 across twelve months: $3,000 divided by 12 is $250 a month. That is how much extra this family sent to Washington each month beyond what it owed. It is real cash flow, roughly the cost of a car payment or a grocery run for a family with kids.

Now suppose the family had kept that $250 a month in its own pocket. What could it have done with the money?

• It could have put $250 a month in a savings account. At a hypothetical 4 percent annual interest rate, depositing $250 at the end of each month, the account would earn about $55 in interest over the year. (Here is the arithmetic: the balances at the start of each month run $0, $250, $500, and so on up to $2,750, which adds to $250 times 66, or $16,500 dollar-months. Multiply by 4 percent divided by 12, and you get $55.) That is $55 that the Treasury's zero percent loan denied the family.
• If the household carries a credit card balance, the picture is starker. At a hypothetical 20 percent annual rate, a $3,000 balance costs $50 a month in interest ($3,000 times 20 percent, divided by 12). The family handed Washington $3,000 interest-free while paying a card company about $600 a year to hold a debt of the same size.
• It could have fixed the transmission in February instead of putting the repair on a card, or paid the dental bill in October instead of waiting for spring.

The IRS does pay interest on overpayments in certain situations, mainly when it fails to issue a refund within a set time after the filing deadline. That is a rule about government delay. It is not a payment for lending the Treasury your money during the year. Check the Form 1040 instructions for the current rule.

The best argument for the big refund

I promised to give the other side its due, so here is the strongest version. It is not a stupid argument, and plenty of thoughtful people make it.

Many households will not save on their own. If you ask a family to set aside $250 a month, the money drifts into the grocery budget, the car, the phone bill. A forced payroll deduction that comes back as a lump sum in the spring acts as a savings account that you cannot raid. The refund is the only large sum some families see all year, and they use it to pay off debts, build an emergency fund or make a big purchase that their monthly budget could never absorb. Take away the refund habit and you take away the savings.

That is the argument. It deserves respect because it is true of some people. Behavioral economists have documented what they call mental accounting: money that arrives in a lump gets treated differently from money that arrives a little at a time.

Now the answer, in three parts.

One, the commitment device exists without the loan. If you want the discipline of forced saving, set up an automatic transfer from your paycheck to a savings account on payday. It is the same discipline, you can earn interest, and you can reach the money in an emergency. If the transmission fails in February, a savings account helps you. A refund in April does not.

Two, forced saving has a price, and the family is paying it. In the hypothetical above, the price is about $55 in lost interest at a modest rate, or many hundreds of dollars a year if the family also carries high-rate debt. A person who needs a commitment device can find a cheaper one.

Three, the argument is an admission. It says the refund is a savings account, and nobody who sells a savings account should be allowed to pay zero. If the Treasury wants to be your bank, let it pay interest like one.

None of this says you must change your withholding. It says you should know what you are doing and decide on purpose. If you value the forced savings more than the interest and flexibility you give up, that is a legitimate choice, and it is yours. The problem is the household that does it by default and then tells itself it is winning.

What a refund also does to the political argument

There is a broader point, and this is where the conservative case gets interesting. A system in which most workers expect a refund trains them to think of taxes as something that happens to them and then partly un-happens in the spring. The refund is the government's best public-relations tool. It converts a year-long drain into a single day of good feeling.

I am not accusing anybody of a conspiracy. Nobody sat down and designed it as propaganda. But it works as propaganda anyway. A taxpayer who writes a large check on April 15 knows exactly what government costs. A taxpayer who gets a big deposit remembers the deposit. The same federal government, taking the same amount, is received very differently depending on the direction of the final transfer.

That matters when the country debates tax policy. It is much easier to cut rates, reform brackets or simplify the code when voters can feel what they pay. It is much harder when the money is hidden in payroll withholding and then returned with a ribbon on it. If you want a clear-eyed look at where each dollar of your pay goes, a paycheck worksheet that shows where every dollar of your pay goes walks through it line by line, and Walking through Form 1040 from the first line to the refund follows the same dollars through the return itself.

What to do about it

Here is the plain, practical sequence, and it takes less than an hour.

1. Look at last year's return. Find the refund line on Form 1040. That number is your annual overpayment.
2. Decide what you want. If you want a refund close to zero, set the goal. If you want a cushion, pick a smaller number than last time. Keep in mind that the opposite error is real: if you underwithhold, you owe tax at filing time and may face an underpayment penalty, so aim near zero rather than far below it.
3. Use the IRS Tax Withholding Estimator. Have your latest pay stub and last year's return handy.
4. File a new W-4 with your employer. It takes effect from the next pay period. You can change it any time during the year, not just in January.
5. Redirect the difference. Whatever your paycheck increases by, move a fixed amount on payday into savings or toward your highest-rate debt, so that it does not get absorbed into everyday spending.
6. Recheck after any big change. Marriage, a baby, a second job, a spouse who starts or stops working, or a raise are all good reasons to revisit the form.

A word for those who owe money rather than receive it: the reverse problem is just as real. A person who owes a large balance every April has been borrowing from the government, in effect, and may owe a penalty. Too little withholding is not a clever strategy. The goal is accuracy, not any particular result.

The verdict

If you want to see how common this belief is, and how many other tax beliefs are just as shaky, read seven tax myths that scare working families and cost them money and decide how many you have been carrying around.

Let me put the verdict as bluntly as I can. A big refund is not a prize. It is a refund of an overpayment. The Treasury is a very large institution that can borrow at rates you will never see, and it still found a way to borrow from you for free. The whole arrangement rests on the fact that most people never do the math.

The conservative position on taxes begins with a simple claim: the money belongs to the person who earned it. A government that withholds more than it needs and returns the rest, without a penny of interest, is treating your wages as its working capital. You do not have to accept that. You have a form, a calculator and a payday, and those three things are all you need.

And for those who are skeptical: try it for a year. Adjust the withholding, put the difference where you can see it, and see what happens to your own sense of the numbers. I suspect you will find that the money feels more like yours when it passes through your hands first. That is the whole point.

The bottom line

• A refund is your own money coming back. A $3,000 refund means you sent about $250 a month more than you owed and got no interest.
• Your Form W-4 controls the amount. Use the IRS Tax Withholding Estimator and Publication 505, then file a new W-4 with your employer.
• If you need forced saving, set up an automatic transfer to a savings account on payday. It does the same job and pays you interest.
• Aim for a refund near zero rather than a large balance due, since underwithholding can bring a penalty.
• Remember Washington's habit when you vote on taxes: money that disappears before you hold it is easy to spend and hard to defend.
