Method: Standard 27% company rate. Target taxable income is derived from the provisional tax paid, plus a buffer of R0. The journal amount balances actual taxable income to that target.
If taxable income is too high (above target): Dr Closing Stock / Cr Inventory — reduces closing stock, raises COGS, lowers taxable income.
If taxable income is too low (below target): Dr Inventory / Cr Closing Stock — increases closing stock, lowers COGS, raises taxable income.
