Consider an unemployed citizen, like a full-time student, that has
an investment generating interest, like in a bank savings account.
If the student earns R22,800 interest in a tax year, then there should
definitely NOT be tax to be paid, because R22,800 interest is exempt.
However, if the student earns R59,749 interest in a tax year, and no other
income at all, then should he pay tax?
Consider that only at R59,750 income does the liability for tax commence, and
then he should pay 18% on R59,750-R22,800=R36,950 which is R6651 tax.
Is this correct?
Let's say that the unemployed student has a JSE stock investment as his
only source of income, which generates an effective 4% dividends pa and 3% interest pa
in the tax year.
Then given that he never sells any stocks (so no CGT), what would be the
maximum stock value he could have without having to pay any taxes?
If it is true that national dividends are tax-free in the investor hands, then
only the 3% interest pa could be taxed. And then only if it produces
income of R59,750 or more in the tax year.
Then the maximum stock value would be R59,749.99/0.03=R1,991,666.33
where he would not have to pay any taxes.
If his stock value increases to R59,750/0.03=R1,991,666.67, then
he would have to pay taxes on R1,991,666.67-R22,800=R1,968,866.67
which would amount to R168,250+40% of (R1,968,866.67-R580,000)
which equals R723,796.67.
So an increase of only 34 cents in the stock value would suddenly
make the student liable for R723,796.67 in taxes.
Have I made an error or incorrect statement in this analysis? Thank you
for the help.
