NY use tax: 5 steps to check the six-month rule

Key takeaways

• Identify when out-of-state business activity began.
• Record when each item entered New York.
• Save the purchase paperwork alongside your timeline.
• Take unclear dates and complicated equipment histories to a tax adviser.

What use tax is and why it catches shop owners

If you run an independent shop, you already know sales tax. You charge it at the register, collect it from customers, and send it to the state. Use tax is the related tax that deals with property you bring into New York and use here. The practical problem for owners is that a vendor in another state may not charge New York tax when you buy, and nobody at your counter will remind you about it later. The question can come up when you are working through your own records, which is why it helps to understand it before it arrives.

The state's examples frame the question around bringing property into New York for use here. That wording matters. The place where you bought the item is only part of the picture. The other part is when the item came into the state and what your business was doing outside New York before that date.

The state's guidance on use tax for businesses is the primary source for how this applies to business purchases. This post walks through the six-month timing rule that the state's examples use, and it points you to the places where the details matter. It is not a substitute for that guidance, and it is not advice about your own facts.

This post is written for owners and managers of independent shops buying equipment from vendors outside New York. If you handle the buying, the invoices, or the books, the timing question below is one you will eventually need to answer, so it is worth learning now, while there is time to keep good records.

The six-month rule in plain words

Most of the confusion comes from one timing question. New York's Tax Law has an exclusion from use tax that applies to certain purchases made by nonresident businesses, and the state's examples cite Tax Law § 1118(2) for it. The state's guidance also says that the Tax Law was amended effective April 10, 2017, to narrow the exclusion from use tax for purchases made by nonresident businesses. A narrower exclusion covers fewer situations than a broader one did. An owner who learned the rule under an older understanding should check the current guidance rather than rely on memory.

Under the rule as the state applies it in its examples, the central question is how long your business had been doing business outside New York before you brought the property into New York. If that period was less than six months, the state's examples treat use tax as owed on the property. If the period was at least six months, the exclusion under Tax Law § 1118(2) applies, and use tax is not owed on that property. The examples are on the use tax for businesses page.

Two details in the examples deserve attention. First, the clock does not start at formation. The state's example describes a corporation formed in Delaware on January 15, 2017. That corporation stayed dormant until March 17, 2017, when it hired employees and bought equipment, and the examples count from March 17. The source for these facts is the same use tax for businesses page. Second, the period ends when the property comes into New York.

The first example: servers that were taxed

The state's first example is the clearest starting point. X Corporation was formed in Delaware on January 15, 2017. It remained dormant until March 17, 2017, when it hired employees and purchased a number of computer servers for use in its business. On June 24, 2017, X Corporation opened an office in New York State and brought some of the servers to New York for use here.

The state's conclusion is direct. Because X Corporation had been doing business outside New York for less than six months before it brought the servers in, covering March 17 to June 24, it owes use tax on the servers. The source is the same use tax for businesses page linked above.

The example uses servers, but the timing question is worth asking about any equipment a shop moves into New York from another state. Replace the servers with display cases, a commercial oven, or a set of point-of-sale terminals, and the first thing to find out is the same: when did your out-of-state activity begin, and how long had it run when the equipment came in?

The example is also about a corporation. An owner running a different structure should check how the exclusion applies to their business.

The second example: same facts, later move

The state's second example changes one fact. It is the same as the first, except X Corporation does not open its New York office and bring some of the servers to New York until October 4, 2017. The period is now March 17 through October 3, which the state describes as at least six months before the servers came in. The state concludes that the exclusion provided in Tax Law § 1118(2) applies, and X Corporation does not owe use tax on the servers. This second example sits on the same page as the first.

Put the two examples side by side and the lesson is plain. The servers, the formation date, and the start of business outside New York were the same in both. The only fact that changed was the date the property came into New York, and that date decided the outcome.

It helps to read the examples slowly. Each one has a start date, a move date, and a result. The arithmetic is simple. The hard part is the facts behind the dates. Did the business really begin operating outside New York on the date you think it did? Did it pause, stop, or move between states? The state's example uses a dormant period explicitly, and your history may not look as clean. Timing is a fact about your business, not a plan to follow. The examples show how the rule works on their facts. They do not tell you what to do with yours.

A simple way to test your own facts is to write the two dates in plain sentences and read them aloud. "My business began operating outside New York on this date. This item came into New York on that date. Between them, the period was this long." If you cannot fill in the first sentence with confidence, the rest of the analysis rests on a guess, and that is the moment to get help.

Turning the rule into a timeline

Shop owners who handle this well usually keep a simple record rather than trying to remember dates. A spreadsheet or a dated folder is enough. The reason to build the timeline is not paperwork for its own sake. When a question comes up months later, a dated record lets you answer it without reconstructing events from memory. It also lets you see, before you buy, which items are likely to fall close to the six-month line.

Here is a practical routine, offered as general guidance and not as legal advice:

1. Write down when your business began operating outside New York. Follow the state's example and use the date activity began, such as when you hired people or started buying for the out-of-state operation. Do not use the date the entity was formed on paper unless it is also the date activity began.
2. Log each item you bring into New York. Record the item, the date it came in, and the vendor it came from.
3. Count the months between the two dates. Note whether the period before the item came in was less than six months or at least six months.
4. Keep the purchase paperwork. Save invoices that show the vendor, the date, the items, and whether New York sales tax was charged.
5. Flag anything close or unclear. Items near the six-month line, or with mixed histories, go to your tax adviser before you file any return.

Keep the log in one place and update it as you go. A timeline that is rebuilt once a year from scattered emails is much harder to trust than one you update each time equipment moves. For related filing habits, see the guide to shop record retention.

Illustrative example: recording separate moves

Imagine an illustrative move of 20 equipment items: 10 arrive together, and 10 arrive later. Log the arrival date for each group and keep the invoices with the entries. Compare each arrival date with the same documented start of out-of-state operations. This gives you separate periods to review instead of treating the whole move as one event.

Situations shop owners run into

A few patterns come up often enough to be worth thinking through. Each one raises the same timing question, but the facts differ, and the state's examples do not cover every variation.

Equipment bought while you already operated elsewhere. Suppose your business ran out of another state for a while, bought equipment there, and later moved that equipment into a New York shop. The question is when the out-of-state operation began, and how long it ran before the equipment entered New York. The state's examples count from when the business started doing business outside New York, so the start date is the fact to pin down first.

Equipment that sat in storage before it moved. Equipment that waited in an out-of-state storage space before it came to New York raises a harder question. The examples measure the period before the property is brought into New York, but they do not address storage. Whether time in storage counts toward the six months is a question to put to your adviser, not one to assume either way.

More than one out-of-state location. If your business operates in more than one state, keep a separate timeline for each location. The examples involve one corporation's out-of-state activity, and they do not explain how multiple locations combine. Ask your adviser before assuming they add together or stand apart.

Equipment with a mixed history. Some items were bought, used, and then moved. Others were ordered in one month and delivered in another. For these, the date that matters is the date the property came into New York, so the dated log described above does most of the work. When the record is incomplete, the safest step is to ask for help before you file, rather than filling the gaps with a guess.

Invoices with no New York tax. A vendor invoice that shows no New York sales tax does not, by itself, settle whether use tax is owed. The rule the examples apply is about timing, so the invoice is evidence to keep, not the answer. Pair it with the dates in your log.

Stock for resale is a separate question

The state's examples concern servers used in a business. They do not address inventory you plan to resell. Whether an exemption applies to goods bought for resale, and how it works, is a different topic, and this post does not cover it.

If you buy inventory from vendors outside New York, check the state's guidance on that subject directly. Confirm with an adviser before you assume either way. An owner who applies the six-month reasoning to stock without checking the separate rules could end up with the wrong answer for the wrong reason. For that separate task, see tax-free stock orders.

When to bring in a professional

Whether use tax applies depends on dates and facts that a blog post cannot see. Bring in a professional if your business has operated outside New York for a period near six months, if you have more than one out-of-state location, or if the equipment you are moving has a complicated history.

A good adviser who knows New York tax will ask when your out-of-state activity started, which entity bought the property, and when each item entered the state. Those are the same facts the state's examples turn on, so having them ready will save time and make the conversation more useful. Ask the adviser to explain the answer in writing, with the reasoning spelled out, so that you can file with confidence and show the reasoning later if a question arises.

Before the meeting, bring the log, the invoices, and a short written summary of when your out-of-state operations began and when each item arrived. A one-page summary is often enough to start a useful conversation, and it keeps the time you pay for focused on your facts rather than on reconstructing them.

Today, choose one equipment purchase and put its invoice, arrival date, and evidence of your out-of-state business start date together in one folder.

The short version

Can I use the formation date?

Use the date business activity began if the business was dormant after formation. In the state's example, employees were hired and servers purchased when that activity began.

What should I do with uncertain dates?

Take uncertain dates to your tax adviser before filing. Bring your log and purchase paperwork so the discussion can focus on the gaps in your record.
