Tacoma, Washington Sales Tax Rate

Port and maritime industry, manufacturing, healthcare, and military (Joint Base Lewis-McChord) drive Tacoma's economy. The Port of Tacoma is one of the largest container ports in North America. Manufacturing includes aerospace components and heavy machinery.

The combined sales tax rate in Tacoma is 10.500%, composed of the Washington state rate of 6.500% plus a local portion of 4.000%. On a receipt, that stacks up as: State 6.5% + Pierce County 0.6% + Sound Transit RTA 0.8% + City of Tacoma 2.5% = 10.4%.

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in Tacoma: tax is $15.75 ($150.00 × 0.10500), total is $165.75.

Tacoma's industrial base runs on port & maritime, manufacturing and healthcare. Under Washington law, qualifying manufacturing equipment, machinery, and industrial materials may qualify for sales tax exemptions or reduced rates, which at a 10.500% 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 (on Washington's prescribed form) on file at time of purchase. Keep records at least four years to cover any state's audit window.

When a Tacoma operation buys equipment or tooling from an out-of-state vendor that does not charge tax, the buyer owes use tax at the full 10.500% combined rate — on a $250,000 machine, that is a $26,250 self-assessed liability, remitted for the Pierce County 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 Tacoma plant working in port & maritime and manufacturing typically buys all four from vendors with no reason to charge Washington tax. Which of them qualifies for a production exemption instead is a Washington 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.

Tacoma producers buying raw materials and components for port & maritime and manufacturing should shield those purchases with valid resale certificates rather than paying tax and chasing refunds.

• Collect a valid resale certificate (on Washington's prescribed form) 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

Distribution is part of Tacoma's economic identity — port & maritime and logistics operations here move goods across jurisdiction lines daily. The rules that bite most often:

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

Tacoma shoppers and businesses routinely cross into Seattle, Olympia, Federal Way and beyond — and in Washington, the combined rate can change at those lines. Of the tracked neighbors, Seattle charges 10.550%, Olympia charges 10.000% and Federal Way charges 10.400% versus Tacoma's 10.500%.

• Seattle (35 mi): combined rate 10.550% — see the Seattle page
• Olympia (30 mi): combined rate 10.000% — see the Olympia page
• Federal Way (15 mi): combined rate 10.400% — see the Federal Way page
• Lakewood (8 mi): outside our tracked Washington city set — verify its current combined rate before invoicing deliveries there

Deliveries are taxed by the destination rules Washington 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 Tacoma can still be required to register in Washington and charge 10.500% 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 Tacoma 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 10.500% rate around Tacoma: untaxed out-of-state purchases delivered here owe matching use tax — $105.00 on a $1,000 order — self-assessed to WA Dept of Revenue / Pierce County / Sound Transit RTA; 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 Washington sales tax guide.

Prescription drugs are exempt from sales tax in Washington. Medical equipment purchased by licensed providers in Tacoma may qualify for exemptions — verify with WA Dept of Revenue / Pierce County / Sound Transit RTA.
