Description
Add goodsValue and whichever of freightCost and insuranceCost their flags include.
A tax or rebate calculation depends on a valuation base, fractional rate, sequencing, and explicit inclusions or exclusions. Those inputs must come from the applicable jurisdiction and transaction rules.
Add goodsValue and whichever of freightCost and insuranceCost their flags include.
When to use this tool
Use Freight Cost Tax Base Gap when you need a supplied-rule tax-base or payment component.
How to use the tool and how it works
- Enter goodsValue, freightCost, insuranceCost, freightIncluded, insuranceIncluded, suppliedTaxBase. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read computedTaxBase, gap. Use the output convention below.
Add goodsValue and whichever of freightCost and insuranceCost their flags include. Return computedTaxBase and suppliedTaxBase minus it.1

| freightIncluded | Freight Included | Required. Boolean. |
| insuranceIncluded | Insurance Included | Required. Boolean. |
| suppliedTaxBase | Supplied Tax Base | Required. Finite number; minimum 0. |

}Limitations and assumptions
- This follows an explicit inclusion model without determining jurisdictional valuation or tax law.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
