Sales tax makes everything you buy a little more expensive, and it’s not just state sales taxes you have to worry about: Some counties and cities tack on their own taxes in addition to the state's, making the bill for certain merchandise even higher. 

If you don't want to shell out a lot of extra money every time you approach a cash register, you'll have to shop in states that either don't have a sale tax or have a very low tax rate.

These locations are the best – and worst – for sales taxes.

States With the Lowest Sales Taxes

The obvious front-runners are the states with no sales taxes at all, but there were only four of them in 2016: Delaware, Montana, New Hampshire and Oregon. Alaska has no state sales tax, but its localities do charge sales tax and the average rate statewide is 1.78 percent. This still puts the state in the top tier with no or very low sales taxes.

Rounding out the top 15 states with the lowest sales tax rates are Colorado at 2.9 percent and Alabama, Georgia, Hawaii, Louisiana, New York, South Dakota and Wyoming, all at 4 percent. Missouri (4.225 percent) and Oklahoma (4.5 percent) just make their way onto the list. 

What's Taxed? 

Most of these states with low sales tax rates exempt food items and many other necessary purchases are spared as well, such as prescription drugs and clothing. But many states have separate, higher taxes for certain purchases like tobacco, alcoholic beverages and gasoline.

New Hampshire will get you if you purchase tobacco products there – a pack of cigarettes will cost you an extra $1.78 as of 2017. You can take heart if you live in Wyoming, however. The state has the lowest beer tax in the country. 

Local Taxes 

Thirty-eight states allow local-level sales taxes. Among those that do, Hawaii, Wisconsin, Wyoming and Maine trail behind Alaska as having the lowest combined rates.

Hawaii logs in at 4.35 percent, Wisconsin at 5.41 percent, Wyoming at 5.42 percent, and Maine at 5.55 percent. 

Residents of Colorado Springs, Colorado voted to increase their city sales tax to 3.12 percent effective 2016 to help pay for highway and road maintenance, but Colorado remains on the short list of low-taxed states overall. 

States With the Highest Sales Taxes

At the other end of the spectrum are states with very high sales tax rates. In some cases, these rates are high enough that shoppers drive across state lines to visit lower-tax or tax-free states when they want to make major purchases. This phenomenon occurs in the Boston area, which isn't too far from tax-free New Hampshire.

California has the dubious honor of having the highest statewide sales tax rate at 7.5 percent. Indiana, Mississippi, New Jersey, Rhode Island and Tennessee all have a 7 percent sales tax. They tie for second place. But Tennessee also allows local sales taxes so the combined state and local rates reach a whopping 9.46 percent in areas – the highest combined rate in the country. Also, food sales are subject to local sales taxes, although not state sales taxes, in Tennessee.

Rounding out the list of the five highest combined state and local taxes are Arkansas at 9.30 percent, Louisiana at 9.0 percent, Alabama at 8.97 percent and Washington at 8.9 percent.

Minnesota and Nevada also have notably high tax rates at 6.875 percent and 6.85 percent respectively, and residents of Clark County, Nevada also saw a hike in their local tax in 2016 when it went from 8.10 to 8.15 percent. Rounding out the 11 states with the highest sales tax rates are Arkansas, Kansas, and Washington, all at 6.5 percent rate. 

It's a Balancing Act

Of course, sales taxes are only one of several ways that state governments can reach into your pocket for the cash that keeps them up and running. Some states take but then they give right back again. They pull much of their revenues from a single tax source and spare residents in other areas. Tennessee's significant combined state and local sales tax rate is offset by the fact that the state only imposes income tax on dividends and investment income – if you live here, your earned income is tax free.

Conversely, although New Hampshire might be sales-tax-free, you'll pay dearly in property taxes if you live there.
