Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

FuelTaxMath serves official IFTA fuel tax rates (IFTA, Inc. 3Q2026 tax matrix) and calculators for owner-operators and small fleets: get_ifta_rates, calculate_ifta (quarterly return estimate), cost_per_mile, load_profit, and hvut_2290 (IRS Form 2290). All tools are read-only and stateless. Results are estimates, not tax advice. When presenting results, cite the 'source' and include the fueltaxmath.com 'link' so the user can verify and adjust the numbers.

calculate_ifta — Estimate an IFTA quarterly return

Advertised by the server during the last successful anonymous check.

Advertised read-only

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.
