Back to school season in the United States runs roughly from late June through early September, with shopping activity peaking in July and most K-12 schools opening their doors between early August and early September. The exact timing depends on where you live, whether you’re shopping for a kindergartner or a college freshman, and how early you want to catch the best deals.
When Schools Actually Start
K-12 start dates vary widely across the country. Schools in southern states tend to open earliest, with many districts beginning classes in the first or second week of August. Districts in the Northeast and Midwest more commonly start after Labor Day, though plenty now begin in mid to late August. The national window stretches from roughly August 1 through the Tuesday after Labor Day in early September.
College and university schedules run a bit later. Most freshmen move into dorms during the last week of August, with classes starting in late August or early September. Upper-class students typically move in a day or two after freshmen. A few schools on quarter systems don’t begin until late September, but they’re the exception.
When Back to School Shopping Peaks
Retailers now launch back to school promotions as early as June, and the National Retail Federation’s 2025 survey found that shopping peaks in July. Most parents aim to finish their purchases by mid-August, which makes July the single most important month for back to school spending. By the time August rolls around, the biggest selection and deepest discounts on supplies, clothing, and electronics are often already winding down.
If you want the widest selection of backpacks, notebooks, and dorm essentials, shop in early to mid-July. If you’re willing to gamble on what’s left in stock, late August clearance sales can offer steep markdowns on whatever didn’t sell during the peak.
Sales Tax Holidays by Month
More than a dozen states offer sales tax holidays timed to back to school shopping, temporarily exempting clothing, school supplies, footwear, and sometimes computers or electronics from state sales tax. These holidays cluster in late July and early August, though the exact dates and eligible items vary by state.
- Mid to late July: A handful of states hold their tax-free weekends in July. For 2026, scheduled dates include mid-July in some southern states and late July in others.
- First two weeks of August: The biggest concentration of tax holidays falls in early August, with numerous states scheduling two or three day windows during the first and second weekends of the month.
- Mid to late August: A few states push their holidays later, with tax-free periods running into the third week of August or, in one case, the entire month.
The savings are real but modest. On a $200 shopping trip in a state with a 6% sales tax, you’d save $12. That adds up more when you’re buying a laptop or outfitting multiple kids. Check your state’s department of revenue website in June or July for the exact dates, item categories, and any per-item price caps that apply.
A Practical Timeline
Here’s how the season typically unfolds, week by week:
- Late June: Retailers begin stocking back to school displays. Early sales on basics like notebooks, pens, and folders start appearing. This is a good time to buy non-perishable supplies if you already have a list from school.
- July: Peak shopping month. The broadest selection of clothing, backpacks, electronics, and dorm supplies is available now. Many stores run their biggest promotional events. Sales tax holidays begin in a few states toward month’s end.
- Early August: The largest cluster of state sales tax holidays falls here. Schools in southern states start opening. Last call for full selection on popular items. Dorm supply shopping ramps up for college students.
- Mid to late August: Most remaining K-12 districts open. College move-in weekends begin. Clearance sales start as retailers make room for fall inventory. Selection thins, but prices drop on what’s left.
- Early September: The last districts (typically those that start after Labor Day) open. College classes are underway nearly everywhere. Retailers pivot fully to fall and Halloween merchandise.
College vs. K-12 Timing
If you’re shopping for a college student, the timeline shifts later and the list looks different. Dorm essentials like bedding, mini-fridges, storage bins, and shower caddies go on sale starting in late June, but the selection is strongest in July and early August. Electronics deals for laptops and tablets tend to peak in late July.
College students also face a compressed move-in window. Most universities assign specific move-in days during the last few days of August, which means any forgotten items need to be bought locally or shipped quickly. Ordering online a week or two before move-in gives you a buffer for shipping delays.
K-12 families, on the other hand, usually receive supply lists from teachers in July or early August. Waiting for that list before buying ensures you get exactly what’s required, though you risk items selling out if you wait too long. A practical middle ground: buy the universal basics (pencils, folders, glue sticks, a backpack) in early July, then fill in teacher-specific requests once the list arrives.
How to Time Your Shopping
The sweet spot for most families is the first two weeks of July. Stock is fresh, promotions are running, and you avoid the mid-August scramble when popular sizes and styles sell out. If your state has a sales tax holiday in late July or early August, hold off on big-ticket items like laptops or a season’s worth of clothing until that weekend.
For everyday supplies like paper, binders, and pens, watch for loss-leader deals at big-box stores. Retailers routinely price common items below cost to get you in the door during July and early August. Stocking up on 25-cent notebooks and dollar folders during these promotions can cut your supply costs significantly, even without a tax holiday.
