Kryptonite, let me admit, your calculations confused the hell out of me so I used the same values but did it my way. Me may well find it ends up giving the same answer, in fact it should if we both worked it right.
What I have done is adjusted the taxable income on a monthly basis so you are taxed correctly. You are allowed to do this, as per SARS, and you merely need to inform your payroll department of your contributions to the RA and get them to reflect this on your pay slip.
PERSON A vs PERSON B SCENARIO
Person A : Earns R50,000 - R7,500 RA contribution = R42,500 taxable earnings
Based on the SARS tax tables they are liable for tax of R10,574 on this R42,500 leaving them with a take home income (ignoring all else) of R31,926.
Person B : Earns R50,000 - R0 RA contribution = R50,000 taxable earnings
Based on the SARS tax tables they are liable for tax of R13,423 on this R50,000 leaving them with a take home income (ignoring all else) of R36,577.
So person B has R4,651 extra disposable income per month
BUT the important thing to not forget is that person A has a R7500 investment in place! So effectively
person A is R2,849 better off.
Peeking at yours quick I see our numbers agree thus far but you seem to sneeze at an additional 61% put towards investment. Yes, you spun the numbers so that
person A was only 5.7% better off but if we calculate the amount going to investment
he is 61% better off (R7,500 vs R4,651) from an investment perspective.
EFFECT OF COMPOUND INTEREST ON ADDITIONAL SAVINGS
Imagine that additional R2,849 going towards investment (at no extra expense to you) compounded annually over a period of, let's say, 20 years. Let's assume a 10% return on average over those 20 years, that is equal to
an additional R2,062,638 in future value or R306,598 in present value.
CGT AND TAX AT TIME OF RETIREMENT
You mention CGT on your 1/3rd lump sum which is inaccurate. There is currently
no CGT or dividend tax liability on retirement savings. This is shown to result in a
boost of 8% to your savings after 40 years of saving (
source)
Your
1/3rd lump sum is also taxed favourably. The first cumulative R300,000 is tax free, the next R300,000 at 18%, the next R300,000 at 27%, and anything thereafter at 36%. So once again you benefit.
You have now taken a 1/3rd of your investment value and, you are right, the remainder will pay out to you as a monthly pension from an annuity and be taxed.
BUT you are likely to already take a knock in your earnings (as I know of very few, if any, people who have saved sufficiently for retirement), you have reduced the amount you are drawing an income from by 1/3rd and once you reach age 65% you enjoy more favourable tax rates. So yes,
although the tax liability is merely delayed you enjoy immense benefits by doing so!
FAVOURABLE TAX ON RETURNS WITHIN THE FUND
Ad if that were not enough benefits, we have also ignored the
favourable tax on your returns within a retirement fund. This is perhaps best illustrated with a random fund fact sheet. This is a moderate fund with exposure to all four asset classes. Taking a look at the 1 year returns you can see that as a result of the favourable tax within an RA fund you earned 11.49% versus someone in a taxed fund (an endowment for example) who only earned 9.69%. Exactly the same fund, only difference being the benefits afforded to retirement funding.
Bottom line is that retirement annuities are not some major scam that was created to pull the wool over the eyes of the public in general. They have distinct benefits which are put in place to attempt to encourage people to save for retirement. The fact that people are so sceptical speaks volumes for the lack of a savings culture in SA.
