What it costs to cross
IFTA charges you for the fuel you BURN in a state, not the fuel you buy there. So a 500-mile pass through Georgia at 6.0 mpg consumes 83.3 taxable gallons whether you fuel here or not. Buy nothing in the state and the whole of it lands on your quarterly return.
| Miles run in Georgia | Taxable gallons | Owed if you buy no fuel here |
|---|---|---|
| 100 | 16.7 | $6.22 |
| 250 | 41.7 | $15.54 |
| 500 | 83.3 | $31.08 |
| 1,000 | 166.7 | $62.17 |
| 2,500 | 416.7 | $155.42 |
That 500-mile pass costs $31.08 in Georgia tax alone. What buying cheap fuel in a low-tax state actually saves you is the difference in the rack price, not the tax: the tax follows the miles and IFTA collects it either way. This is the single most misunderstood line in owner-operator accounting.
