In terms of legislation, you must draw a pension income from your living annuity at a minimum of 2.5% per year and a maximum of 17.5% per year of the value of the residual capital. As the annuitant, you can choose whether to draw down on a monthly, quarterly, bi-annual or annual basis, with this largely being dependent on your personal circumstances and income needs, bearing in mind that your income does not fluctuate even if the value of your investment changes.
On the anniversary of your policy each year, you have the option to change the level at which you draw down from your investment, although this should be done in partnership with your financial advisor to ensure that your withdrawal rate is sustainable. In general, to protect your capital you will need to draw down at less than 4% of the value each year. If you draw too much from your living annuity, you may reach the 17.5% cap too soon, and this can severely impact your cash flow later in retirement.
However, as a response to the financial hardship suffered by many as a result of Covid-19, National Treasury has decided to relax the living annuity drawdown rules temporarily. As such, annuitants are permitted to adjust their drawdown rates to between 0.5% and 20% for a period of four months, from June 1 to September 30, 2020.
However, before adjusting the draw levels from your living annuity, it is always advisable to seek independent financial planning advice. From your question, it is unclear whether you have any discretionary investments in place that you are able to access. Further, it is unclear how the underlying assets in your living annuity are invested and whether you are taking appropriate investment risk for your investment timeline, bearing in mind that you are only four years into early retirement. The fact that increasing your drawdown will result in you eating into your capital is of concern, especially as you may have many years of retirement ahead of you.
My suggestion is to get advice from an independent advisor who can take a holistic view of your financial position, including: your budget and living expenses, any other investments you have in place, whether you have other assets that can be liquidated, how your underlying assets are invested, and what your goals are for the rest of your retirement.
Being a relatively young retiree, you could have a number of decades ahead of you that you need to plan for, and we strongly recommend that you seek expert advice.
