Sales tax basics

In short

A friend of mine ran a little candle shop for two years before she learned that the sales tax she collected was never really hers. If you sell goods to customers, you have probably wondered who keeps the tax you add at the register. The state does. You are just holding it for them. Find out whether your state charges sales tax and whether you need a seller's permit before your first sale. Keep the tax you collect in its own account so you never spend it by mistake. File on time, even in a month when you sold nothing. That habit will save you more grief than any trick.

The whole of it

What it is

I once watched a man at a farm stand hand back a customer's change, then pause and say, "That includes the state's share." I liked that. He understood what many new owners miss. Sales tax is a tax on the buyer, and the seller is the one who collects it and sends it in.

If you are holding a cash box and wondering how it works in your state, here is the plain picture. Most states charge sales tax, and many cities and counties add a little more on top. A few states charge none at all. The tax is set by the state and local governments, not by the federal government. That is why your neighbor across the state line may follow different rules than you do.

You do not pay this tax out of your own profit. Your customer pays it on top of the price. You collect it, you report it, and you send it to the state. Think of yourself as a careful courier carrying someone else's letter.

How it works

A woman I know sold hand knit scarves at craft fairs and figured the tax was a problem for bigger businesses. She was wrong, and a kind letter from the state told her so. Many states ask you to register first. The registration gives you a permit or license that lets you collect the tax legally. Check your own state's department of revenue website to see what it asks of you.

Once you are registered, the steps are simple. You add the tax rate to the price of each taxable sale. You record the tax separately from the sale. Then, on a schedule your state sets, you report your sales and send in what you collected. Some states want a return every month. Others allow every quarter or once a year for smaller sellers.

Not everything is taxable. Rules differ by state, and they can surprise you. Some states tax most goods but not groceries. Some tax certain services and skip others. Clothing may be taxed in one place and free of tax in the next. Your state's revenue department publishes lists, and it is worth reading yours.

Then there is the matter of who buys from you. If a buyer plans to resell your goods, they can often give you a resale certificate. That form says they will collect the tax later, so you do not charge it now. Keep every certificate you receive. If the state ever asks, that paper is your proof.

Selling across state lines adds another wrinkle. In 2018, the Supreme Court decided South Dakota v. Wayfair. After that ruling, states may require out of state sellers to collect tax once they pass a set level of sales into that state. This is called economic nexus. It just means enough business in a place that the state can ask you to collect. Each state sets its own threshold, so look up the states where your customers live.

The numbers, and where to find yours

You have probably wondered where to look for your rate, and I will not guess at it for you. Your state's rate is set by law and it can change. The combined rate for your city or county is also set locally. Your state department of revenue website is the official place to find both.

Here are the figures the site will fill in for you. The state sales tax rate where you sell is the current figure, which the official source publishes each year. The sales level at which an out of state seller must start collecting is the current figure, which the official source publishes each year. Your local add on rate is the current figure, which the official source publishes each year. Check the date beside each figure, because these numbers move.

Your filing schedule is also set by your state. It may depend on how much tax you collect. A small seller might file once a quarter, while a busy one files every month. Your registration paperwork or your online account with the state will tell you which one you are on. Put those due dates on your calendar the day you learn them.

A worked example

A friend of mine, Maria Delgado, sells handmade soap from a booth and a small website. Her state charges 6 percent, and her county adds 1 percent. Her combined rate is therefore 6 plus 1, which is 7 percent. These are her own plain figures for the story, not any real rate.

One Saturday she sells a gift box for 40 dollars. She multiplies 40 by 0.07. That gives her 2.80 dollars in tax. The customer pays 40 plus 2.80, which is 42.80 dollars. Maria puts the 40 dollars in her sales record and the 2.80 in her tax record.

By the end of the month, she has sold 3,000 dollars of taxable soap. She multiplies 3,000 by 0.07. That is 210 dollars of tax collected. She has kept that 210 dollars in a separate savings account, so it is sitting there when the return is due.

Suppose she also sold 500 dollars of soap to a shop that gave her a resale certificate. That 500 dollars is not taxed at her register. She lists it on her return as a sale for resale. Her taxable total stays at 3,000 dollars, and her tax due is still 210 dollars.

She files the return, sends the 210 dollars, and keeps a copy. It takes her twenty minutes. Maria told me the worst part was the dread before she learned how it worked. After that, it was just a chore.

Where it goes wrong

I have seen good people get into a hole here, and it is almost never on purpose. The first trouble is spending the tax money. It sits in your account looking like income, and a slow month can pull at you. Then the return comes due and the cash is gone. Many sellers find it easier when the tax money sits in its own account from the first sale.

The second trouble is skipping registration. Some new sellers think a small operation is too little to matter. States do not always agree. Selling without a permit where one is required can bring back taxes, penalties, and interest. That can cost far more than the tax itself.

The third is filing late or not at all when you had no sales. Some states still want a return showing zero. A missed one can bring a fee. Check your state's rule to see whether yours does.

Another common slip is charging the wrong rate. In many states the rate depends on where the sale is delivered, not where you sit. Selling online makes this harder. Your state's revenue site can help you find the right rate for an address.

Last, people forget to keep records. Save your sales records, your resale certificates, and your filed returns. The state's own guidance will tell you how long to keep them. Good records turn a scary letter into a small matter.

Questions to answer before you leave this page

Do you know whether your state charges sales tax and what your combined local rate is? Have you registered for a seller's permit, or checked that you do not need one? Do you keep the tax you collect in a separate account so you cannot spend it by mistake? Do you know your filing schedule, and are the due dates on your calendar? Have you looked at your state's list of taxable and exempt items to see where your products fall? If you sell to other states, have you checked whether you passed the threshold in any of them? Where will you keep your resale certificates and filed returns so you can find them in a hurry?
