Total value including sales taxValue excluding tax + output tax
At 18%, tax within an inclusive value is inclusive amount × 18 ÷ 118.
Donations and charities
A charitable payment does not normally reduce output sales tax, and it is not input tax merely because the recipient is charitable.
The calculator therefore reports donations separately in the cash-flow reconciliation and does not use them to reduce sales-tax payable.
Transfers of goods without consideration, deemed supplies, exemptions, and qualifying charitable entities require transaction-specific review.
