The Niagara County sales tax rate is 8% on most taxable purchases. That total is split evenly: 4% goes to New York State and 4% stays local. You pay it whether you’re buying a sofa in Niagara Falls, eating lunch in Lockport, or booking a hotel room in the county.
Why the Local Share Is 4% Instead of 3%
New York Tax Law Section 1105 imposes the statewide 4%.1New York State Senate. New York Tax Law 1105 – Imposition of Sales Tax Section 1210 then lets counties add their own local tax, generally capped at 3%.2New York State Senate. New York Tax Law 1210 – Sales and Compensating Use Taxes Niagara County has special legislative authorization to go one point higher, charging a full 4%, with the extra penny on every dollar dedicated to the county’s share of Medicaid costs.3Niagara County. Niagara County Legislature Resolution AD-019-25
That extra authorization isn’t permanent. It runs through November 30, 2027, and the state legislature has to renew it before then. If renewal doesn’t happen, the county rate drops to 3% and the combined rate falls to 7%. Until then, every taxable dollar in the county carries the full 8%.
What You Pay 8% On
Most physical goods sold at retail are taxable: furniture, appliances, electronics, motor vehicles, and similar items.4New York State Department of Taxation and Finance. Quick Reference Guide for Taxable and Exempt Property and Services Services are generally exempt unless New York singles them out as taxable. The common taxable services include restaurant meals and drinks, hotel room occupancy, utilities, and repair or maintenance work on physical property.1New York State Senate. New York Tax Law 1105 – Imposition of Sales Tax Certain information services and storage of physical goods are also taxable.
Software and SaaS
New York treats prewritten computer software as a physical product no matter how it’s delivered. A boxed copy, a download, and a cloud subscription are all taxed at 8%.5New York State Department of Taxation and Finance. Computer Software This picks up most SaaS products used by local businesses and residents. Truly custom software built for a single client is the exception, though it becomes taxable if later resold.
Shipping and Delivery
Delivery charges follow the product. If what you bought is taxable and the seller adds a shipping fee to your invoice, the fee is taxed at 8% too. If the product is exempt, so is the shipping. On a mixed invoice, the seller has to allocate the delivery charge between the taxable and nontaxable items, or the whole charge gets treated as taxable. One useful carve-out: if you hire a delivery service separately, on its own invoice, that transportation charge isn’t taxable.6New York State Department of Taxation and Finance.

What’s Exempt
Most unprepared food and groceries are exempt from sales tax entirely, though candy, soft drinks, and alcoholic beverages are not. Prescription and over-the-counter drugs, medical equipment, prosthetic devices, and hearing aids are also fully exempt.7New York State Senate.

Clothing Is Not Fully Exempt in Niagara County
This is where Niagara County differs from New York City and some other localities. Under state law, clothing and footwear under $110 per item are exempt from the state’s 4% portion. Niagara County has not opted into that exemption for its local share.8New York State Department of Taxation and Finance. Clothing and Footwear Exemption A $90 pair of shoes bought in the county still carries 4% in local tax. Clothing priced at $110 or above is taxed at the full 8%.9New York State Department of Taxation and Finance. Publication 718-C – Sales and Use Tax Rates on Clothing and Footwear
Resale Purchases
Businesses buying inventory for resale can skip the tax at purchase by giving the seller a completed Form ST-120. The buyer has to hold a valid Certificate of Authority from New York, or be registered to collect sales tax elsewhere. The certificate only covers items genuinely intended for resale in their current form or as a component of another product. Contractors can’t use it to buy materials and supplies.10New York State Department of Taxation and Finance. Resale Certificate – Form ST-120
Online and Out-of-State Purchases
Buying from an out-of-state seller doesn’t let you escape the 8%. When the seller doesn’t collect New York tax, you owe compensating use tax at the same rate. This covers online orders, items you buy while traveling, and goods shipped from other states. Individuals report use tax on their New York income tax return; businesses report it on their sales tax return.
In practice, most large online retailers already collect the tax. An out-of-state business has to register and collect once it has made more than $500,000 in sales of physical goods delivered to New York and completed more than 100 such transactions during the prior four sales tax quarters. Both thresholds have to be met.11New York State Department of Taxation and Finance. Registration Requirement for Businesses With No Physical Presence in New York State

Any business making taxable sales in Niagara County has to register with the New York State Tax Department before its first transaction, even if sales are seasonal or one-off at a flea market or craft fair.12New York State Department of Taxation and Finance.

Filing Frequency and Deadlines
New York sets filing frequency based on how much tax you collect. New registrants usually start as quarterly filers. Collect $3,000 or less across four quarters and the Tax Department may move you to annual filing. Hit $300,000 or more in taxable sales in a single quarter and you move to monthly.14New York State Department of Taxation and Finance. Filing Requirements for Sales and Use Tax Returns
Returns are due within 20 days after the end of the reporting period. New York’s sales tax quarters end May 31, August 31, November 30, and February 28/29, so a March-through-May return is due June 20. Annual returns are due March 20. Filing goes through the Tax Department’s Web File system.15New York State Department of Taxation and Finance. File Online With Sales Tax Web File
Timely filers who pay in full by the deadline can claim a vendor collection credit equal to 5% of the taxes reported, capped at $200 per period.16New York State Department of Taxation and Finance. Vendor Collection Credit
Late Filing Penalties
Missing a deadline costs 10% of the tax due for the first month, plus 1% for each additional month, up to 30% of the tax owed. The minimum penalty for failing to file is $50 even if you owe nothing. File more than 60 days late and the minimum jumps to $100 or 100% of the tax due, whichever is less.17New York State Department of Taxation and Finance.

Keep Your Records
Businesses have to keep sales tax records for at least three years after filing the related return. That means register tapes, invoices, purchase records, exemption certificates, and bank statements, all detailed enough that an auditor can independently verify the taxable status of each sale and the tax collected.19New York State Department of Taxation and Finance.
