Does Missouri charge a demand charge on EV charging?

In the Kansas City metro, barely: Evergy's EV-exclusive schedules bill no demand charge beyond a facility charge of about $2.55 to $4.23 per kW bundled, on the trailing twelve-month maximum — which resolves to the current month for a site with a steady peak. In St. Louis, Ameren's standard rate bills about $4.73 per kW bundled on the current month's peak with no ratchet.

Is there a per-kWh charging tax in Missouri?

No — none is in force. Missouri funds roads from EVs through a driver-side registration decal. A statutory task force has studied usage-based options; if a per-kWh tax is ever enacted, the model carries it as a configuration change from the effective year.

What taxes does the model include for a Missouri site?

Sales tax on the utility bill and hardware at the site's combined rate (9.68% St. Louis City, 9.98% Kansas City), Kansas City's 10% utility license taxes folded into the Metro row, and business personal property at about 2.7% to 2.8% of depreciated cost per year — among the heaviest covered. St. Louis City's utility gross-receipts tax on the Ameren bill is disclosed rather than folded pending the ordinance text, and both cities' 1% earnings tax on in-city profits is disclosed rather than modeled.

Tesla Supercharger ROI in Missouri

Missouri's two metros run on opposite designs. The Kansas City metro has filed EV-exclusive schedules on both sides of the state line — Evergy's Business EV Charging Service prices three time-of-use periods with no demand charge beyond a small facility charge. St. Louis has no EV-specific rate at all, so a site takes Ameren's large general service schedule — a demand charge with unusually little fine print: the current month's peak, a 100 kW floor, and no ratchet. What separates the metros most is the municipal tax layer: Kansas City's 10% utility license taxes ride the Evergy bill, and both cities levy a 1% earnings tax inside city limits.

What makes Missouri economics distinct

Kansas City filed the EV rate; St. Louis did not

Evergy Missouri Metro's BEVCS is the same EV-exclusive design Evergy files in Kansas: time-of-use energy mapping directly onto peak, off-peak, and overnight windows, with a facility charge of about $4 per kW bundled as the only demand-side line. Ameren Missouri's book has no EV schedule — its standard large general service rate is the St. Louis row, at a bundled $4.73 per kW and a flat energy price.

A demand charge with no ratchet in St. Louis

Ameren's 3(M) bills demand on the current month's 30-minute peak with a 100 kW floor and no trailing-month clause — one of the few covered demand charges with no ratchet at all. Energy prices in usage blocks so wide that a charging site never leaves the first block, so the flat modeled rate is exact over the whole expressible range.

The suburbs are their own utility — and cheaper

St. Joseph and the Kansas City east and south suburbs (Lee's Summit, Liberty, Platte City) sit in Evergy Missouri West territory, a separate rate book that completed its rebase in January 2025. Its BEVCS runs the same design at lower prices and sits outside Kansas City's license taxes — at default volumes the West site models cheapest of the three Missouri rows.

Both rate books move in 2027

Ameren filed a rate case in June 2026 (about 10%, order expected around May 2027) and Evergy Missouri Metro filed in February 2026 (new rates expected January 2027 — the first BEVCS change since 2023). The model carries the currently effective figures and re-derives at each order; the direction and size land with the commission.

Missouri tax profile

Sales tax on hardware: 9.68%
Business personal property tax: 2.7% of equipment value (example rate)
Clean-fuels credit: no program
Per-kWh charging excise: none

Missouri tax defaults applied: no clean-fuels credit program exists in Missouri (the LCFS revenue line is $0), and LLC costs are $0 — Missouri LLCs file no annual report and the franchise tax was repealed in 2016. Sales tax defaults to St. Louis City's 9.679% combined rate; Kansas City runs 9.975% and the field is editable. Business personal property assesses at one-third of value against the city levy — about 2.7% of depreciated cost per year in St. Louis City and 2.8% in Kansas City, among the heaviest in the covered set. No per-kWh charging tax exists in Missouri. Kansas City and St. Louis City each levy a 1% earnings tax on business profits earned inside city limits — an entity-level tax the engine does not model, disclosed for in-city sites.

Missouri programs and incentives

Evergy Commercial EV Charger Rebate (Schedule CEVCR)

A filed tariff rebate of 40% of charger and customer-side wiring costs for public, workplace, fleet, and multifamily charging through March 2028, conditioned on taking service under BEVCS with pre-approval. Site-specific awards enter the model through the grant inputs.

MoDNR DCFC grants (VW settlement lineage)

Historically up to 80% of purchase, install, and maintenance costs for public DC fast charging; round status varies.

NEVI (federal, MoDOT-administered)

About $99 million of federal corridor charging funding across FY22–26, administered by MoDOT in award rounds.

Missouri charging market

Missouri carries roughly 36 Supercharger stations along I-70, I-44, and I-35. Ameren serves St. Louis and most of eastern Missouri; Evergy Missouri Metro serves Kansas City proper and Evergy Missouri West the outer metro and St. Joseph. Springfield and Columbia run municipal utilities the model does not cover, as does Independence inside the Kansas City metro — addresses there see a named-utility notice rather than a wrong auto-selection. Within the metro counties the Metro/West boundary is approximated: eastern Jackson County suburbs auto-select the Metro book and the selector stays editable.
