Sales Tax

Sales Tax is a consumption tax imposed by state and local governments on the retail sale of goods and, in some jurisdictions, services. This tax is calculated as a percentage of the purchase price and is collected by sellers at the point of sale, then remitted to the appropriate tax authority. Unlike income taxes that target earnings, sales taxes are transaction-based, affecting consumers when they purchase taxable items.

Sales tax rates and rules vary significantly across states and localities. Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon, though Alaska allows local jurisdictions to impose sales taxes. Among states with sales tax, rates range from less than 3% to over 7% at the state level, with many counties, cities, and special districts adding their own local sales taxes. This creates combined rates that can exceed 10% in some locations. What items are taxable also varies widely, with most states exempting groceries, prescription medications, and certain services, while taxing clothing, electronics, furniture, and other retail goods.

Businesses that sell taxable goods or services must register for sales tax permits, collect the appropriate tax from customers, maintain detailed records, and file periodic sales tax returns (typically monthly, quarterly, or annually) remitting collected taxes to state and local authorities. Failure to properly collect and remit sales tax can result in significant penalties, interest charges, and personal liability for business owners.

For federal income tax purposes, you can deduct state and local sales taxes as an itemized deduction on Schedule A instead of deducting state income taxes, though not both. The total state and local tax (SALT) deduction, whether income or sales taxes, is capped at $10,000 ($5,000 for married filing separately). Taxpayers in states without income tax typically benefit from deducting sales taxes, using either actual receipts or IRS-provided tables based on income and family size.

Sales tax differs from use tax, which applies to items purchased outside your state for use within your state when sales tax wasn’t collected at purchase, commonly relevant for online purchases and cross-border shopping.
