| Entered amount | Choose whether the entered taxable amount already includes tax. The extraction formula differs from adding tax. |
Understanding your result
Tax, net amount and gross amount describe the explicitly stated jurisdiction, period and taxable base. An inclusive total extracts the tax component; an exclusive amount adds it.
Common mistakes
- Using a city or country name without checking the exact address, effective period and taxable classification.
- Adding tax to an amount that already includes it, or treating special classifications as covered by a general rate.
Check your calculation
- Compare net + tax with gross using the stated rounding policy, and confirm the locality/rate in the official source.
