🟢get_ifta_rates(jurisdiction, fuel, quarter)
Official IFTA fuel tax rates (USD per US gallon) by US state / Canadian province from the IFTA, Inc. quarterly tax matrix. Current quarter: 3Q2026. Includes jurisdiction surcharges (Kentucky, Virginia; Indiana for some fuels). Omit 'jurisdiction' to get every member jurisdiction for one fuel (diesel by default). Cite the returned link and source.

}🟢calculate_ifta(jurisdictions, mpg, fuel)
Estimates IFTA fuel tax owed or credited per jurisdiction for a quarter using official 3Q2026 rates. Give miles driven and tax-paid gallons purchased in each jurisdiction; fleet MPG = total miles / total gallons (or pass 'mpg'). Taxable gallons = miles / MPG; net = taxable - purchased; surcharges (e.g. KY, VA) apply to all taxable gallons. Cite the returned link.
