McKinney, Texas Sales Tax Rate

Technology, healthcare, manufacturing, and corporate HQs. Fast-growing Collin County suburb with major employers like Raytheon, Torchmark, and Encore Wire.

The combined sales tax rate in McKinney is 8.250%, composed of the Texas state rate of 6.250% plus a local portion of 2.000%. On a receipt, that stacks up as: State 6.25% + City 2.0% = 8.25% (Collin County has no county sales tax).

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in McKinney: tax is $12.38 ($150.00 × 0.08250), total is $162.38.

McKinney's industrial base runs on technology, healthcare and manufacturing. Under Texas law, qualifying manufacturing equipment, machinery, and industrial materials may qualify for sales tax exemptions or reduced rates, which at a 8.250% combined rate is real money on every capital purchase.

• Production Machinery & Equipment: Machinery used directly in manufacturing tangible personal property for sale
• Industrial Materials & Consumables: Raw materials that become component parts of finished products
• Pollution Control Equipment: Equipment mandated for environmental compliance
• R&D Equipment: Machinery used predominantly for research & development

Documentation required: A valid exemption certificate (Form 01-339 in Texas) on file at time of purchase. Keep records at least four years to cover any state's audit window.

When a McKinney operation buys equipment or tooling from an out-of-state vendor that does not charge tax, the buyer owes use tax at the full 8.250% combined rate — on a $250,000 machine, that is a $20,625 self-assessed liability, remitted for the Collin location.

It reaches further than the machine itself. Tooling and dies bought abroad, the CAD/CAM, ERP and MES licences that run the floor, and the spare-parts and maintenance contracts behind them all land in the same accrual, and a McKinney plant working in technology and healthcare typically buys all four from vendors with no reason to charge Texas tax. Which of them qualifies for a production exemption instead is a Texas question — the manufacturing exemptions guide works through it. The control is unglamorous: flag every invoice that arrives without tax for review before it is paid, rather than finding them at audit.

McKinney producers buying raw materials and components for technology and healthcare should shield those purchases with valid resale certificates rather than paying tax and chasing refunds.

• Collect a valid resale certificate (Form 01-339 in Texas) before the first tax-exempt purchase
• Verify certificate includes: purchaser name, address, permit number, signature, date
• Renew certificates annually or per state requirements
• Retain certificates at least four years to cover any state's audit window

Freight moving through McKinney crosses jurisdiction lines, and each hop has tax consequences. The rules that bite most often:

• Freight Charges: Separately stated freight charges are taxable
• Warehousing Services: Storage fees may be taxable depending on Texas law
• Cross-Docking/Transloading: May create nexus in multiple jurisdictions
• Inventory in Transit: Verify sourcing rules for drop-shipments and third-party fulfillment

McKinney shoppers and businesses routinely cross into Plano, Frisco, Allen and beyond — and in Texas, the combined rate can change at those lines. The tracked neighbors — Plano — currently share McKinney's 8.250% combined rate, so the delivery address matters less for rate than for sourcing documentation here.

• Plano (8.25%): combined rate 8.250% — see the Plano page
• Frisco (8.25%): outside our tracked Texas city set — verify its current combined rate before invoicing deliveries there
• Allen (8.25%): outside our tracked Texas city set — verify its current combined rate before invoicing deliveries there
• Melissa (8.25%): outside our tracked Texas city set — verify its current combined rate before invoicing deliveries there
• Denton (8.25%): outside our tracked Texas city set — verify its current combined rate before invoicing deliveries there

Deliveries are taxed by the destination rules Texas applies, not by where the store sits — when an order ships across one of these city lines, re-check the rate for the exact address.

Since South Dakota v. Wayfair, a seller with no premises, staff or stock anywhere near McKinney can still be required to register in Texas and charge 8.250% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why McKinney and its neighbours have to be priced separately. The registration mechanics and the trailing-twelve-month counting rules are in the economic nexus guide.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.

Three obligations follow the 8.250% rate around McKinney: untaxed out-of-state purchases delivered here owe matching use tax — $82.50 on a $1,000 order — self-assessed to Collin County / City of McKinney; sellers with physical presence or economic nexus must register before collecting; and wholesale sales need a valid resale certificate on file at transaction time. Filing mechanics, exemption certificates, and audit preparation are covered in the Texas sales tax guide.

McKinney's technology employers sell into every state's rules. SaaS and digital services taxability in Texas: Taxable as a data processing service (subject to a 20% state tax exemption, meaning only 80% of the price is taxable).
