Five Financial Mistakes Doctors Commonly Make

Ruvan Grobler • January 22, 2026

Medicine is built on precision, protocols, and evidence-based decisions. Financial life, unfortunately, is not. For many doctors, success arrives early in one area of life and much later in others—time, structure, and strategic planning often lag behind income.

 

Over the years, a few patterns come up repeatedly when working with medical professionals. These are not mistakes born from ignorance or carelessness, but rather from being busy, successful, and focused on patients first.

 

Here are five of the most common financial missteps doctors make—and why addressing them early can materially change long-term outcomes.

 

1. Being “Cash Heavy” Feels Safe… Until It Isn’t

 

Holding large cash balances is often seen as prudent. Cash is liquid, familiar, and low-stress. For doctors with volatile workloads or private practices, this feels especially comforting. The problem? Cash is one of the most tax-inefficient assets for high earners.

 

While interest income enjoys a modest annual exemption, anything above that threshold is taxed at your marginal rate. For many doctors, this means a significant portion of “safe” interest returns never actually reach them. Add inflation into the mix, and the real (after-tax, after-inflation) return on excess cash can quietly turn negative.

 

Cash has a role—but without intention and limits, it often becomes a silent drag on long-term wealth.

 

2. Paying More Tax Than Necessary (Without Realising It)

 

Doctors are among the most heavily taxed professionals in South Africa, yet tax planning is often treated as a once-a-year exercise rather than an integrated strategy. The issue isn’t usually under-reporting—it’s under-structuring.

 

Different investment vehicles are taxed in very different ways. Income tax, capital gains tax, and dividend tax don’t just affect returns; they compound over time. Two portfolios with the same gross return can end up worlds apart after tax if they’re structured differently.

 

When investment decisions are made in isolation—without considering tax, time horizon, and estate implications—the cost isn’t obvious in year one. It shows up quietly over decades.

 

3. Offshore Exposure: Opportunity or Overreaction?

 

Global diversification is important. Offshore exposure can reduce concentration risk and unlock opportunities unavailable locally. However, many investors move money offshore without a clear strategy—often driven by headlines, fear, or currency anxiety rather than long-term planning.

 

Key questions are frequently overlooked:

 

  • How much offshore exposure is appropriate for your situation?
  • Which structures are most efficient?
  • How does this affect tax, liquidity, and future repatriation?

 

Offshore investing isn’t a binary decision. The value lies in how, where, and through what structure exposure is obtained—not simply in moving money abroad.

 

4. Paying Everyone Else First

 

Doctors are natural caregivers. Practices, staff, patients, families—everyone’s needs come first. Personal savings often come last. The data is clear: South Africa’s domestic savings rate remains worryingly low. Even among high earners, inconsistent or delayed personal investing is common.

 

The risk isn’t lifestyle inflation—it’s time. Missed early contributions can’t be recovered later, no matter how high income becomes. Compounding rewards consistency, not intention. Paying yourself first isn’t about sacrifice; it’s about ensuring today’s success translates into future independence.

 

5. Using the Wrong Investment Structures

 

This is arguably the most expensive mistake—and the least visible.

 

Many doctors accumulate investments across multiple platforms, policies, and accounts over time. Each decision may have made sense in isolation, but together they can create inefficiencies around:

 

  • Tax
  • Access
  • Estate planning
  • Intergenerational transfer

 

The structure holding the investment often matters as much as the investment itself. Over a 20- or 30-year horizon, the difference between “adequate” and “optimal” structuring can be substantial—even if the underlying returns are identical.

 

The Common Thread

 

None of these mistakes stem from poor decision-making. They stem from complexity, time pressure, and the reality that financial planning is a discipline of integration—not isolated choices. Income, tax, investments, offshore exposure, and estate planning don’t operate independently. When aligned, they reinforce one another. When they’re not, value leaks out quietly year after year.

 

For professionals who spend their lives mastering complexity in one field, the challenge is recognising that financial clarity often requires the same level of specialised thinking. Because in finance—just like in medicine—the biggest risks are rarely the obvious ones.

Die Oorlog in die Midde-Ooste en jou Beleggingsportefeulje

By Dr. Riaan Botha • March 4, 2026
Beleggers is onseker oor wat die invloed van die oorlog in die Midde-Ooste op hul beleggingsportefeuljes gaan wees. Gaan die vernietiging van infra-struktuur, die wisseling in die prys van olie en die sterkte van die Suid-Afrikaanse geld eenheid teenoor die Amerikaanse dollar die prestasie van hul beleggingsportefeuljes nadelig raak? Niemand weet ook nie hoe lank die oorlog gaan duur en of vyandighede gaan uitbrei na ander lande nie. Dit is egter belangrik om die volgende rakende Bovest se beleggingsportefeuljes te onthou: Diversifikasie . Portefeuljes is saamgestel uit die verskillende bateklasse naamlik aandele, efekte, kontant en gelyste eiendom. Indien die olie pryse styg weens ’n tydelike tekort aan olie gaan sekere aandele se pryse daal. Die ander bate-klasse sal egter nie so negatief geraak word nie. Verskillende beleggingsfondse . Die Fonds van Fondse (FoF) metodiek word gebruik om beleggingsportefeuljes saam te stel. Dit verseker dat beleggingsportefeuljes vinnig herstel na onvoorsiene gebeure soos oorloë of natuurrampe. Die verskil in die beleggingstyle van die verskillende fondsbestuurders verseker ook bo-gemiddelde beleggingsprestasie. Aktiewe bestuur. Die beleggingskomitee bestuur die beleggingsportefeuljes aktief deur die verskillende ekonomiese siklusse. Beleggers het anders as spekulante ’n lang termyn benadering oor beleggingsprestasie. Die onlangse geskiedenis met die Covid-pandemie asook die finansiële krisus van 2008 het bewys dat geduld bo-gemiddelde beleggings prestasie verseker. Alhoewel die huidige oorlog in die Midde-Ooste finansiële markte nadelig raak, weet ons dat ons as beleggers geduldig moet wees om hierdie onseker tye te deurstaan en nie emosionele veranderings aan portefeuljes maak nie. Indien lesers enige navrae oor hul portefeuljes het, kan hulle hul Bovest adviseur skakel.

Die Verandering van Lewensfase van Seniors

March 3, 2026
Dit is tyd om ankers op die plaas op te trek. Van Wyk Louw het gesê as die getye verander moet jy die bakens verskuif. Ons moet los items verkoop, moet minder maak, die volgende lewe vereis ‘n eenvoudiger bestaan met minder lewensgoedere binne kleiner spasies. Ons durf die proses moedig aan en dit neem tyd. Daar is ‘n menigde afvalmetaal items op die plaas en dit moet verwyder word – ironies, ook dit moet ‘n nuwe lewensfase in ‘n nuwe omgewing binnegaan. Ons laai die eerste vrag van vele. Daar is metaalpype, heiningmateriaal, stukke van ou landbouimplemente, en haas enige iets wat een of ander metaal bevat. My eindbestemming is Modimolle se skrootwerf. By die ingang is daar ‘n ketting wat toegang reguleer. Ek word beveel om bo-op ‘n metaalstrook te ry, net om later agter te kom dat dit eintlik ‘n weegbrug behels – ‘n noodsaaklike kritiese item in die proses van metaalverhandeling. Ek moet uitklim want saam word ek nie geweeg nie. Ek dink…in my huidige kondisie sou ek nogal ‘n goeie opbrengs in skrootmetaalpryse kon behaal. ‘n Werker in ‘n kantoortjie teken die gekombineerde gewig van die voertuig en vrag aan. Van hier word die vrag stuk-stuk volgens die soort metaal afgelaai. ‘n Man wys my die pad aan tussen hope metaalitems. ‘n Besige landskap van bedrywighede ontvou voor my – vurkhysers, trekkers, blouvlamme wat metaal opsny, waentjies wat afval na hulle bestemmings op die perseel vervoer en arbeiders wat lorries en sleepwaens aflaai. Eenkant lê ‘n wrak van ‘n motor, ‘n laaste staanplek voordat dit in stukke opgesny en inmekaar gepers sal word. Terwyl ek staar kan ek nie help om ‘n vermenslikte beeld in die motor te sien nie. Dit lyk vir my soos iemand wie se wiele afgekom het, voor is dit in die bek geskop en van agter het dit ‘n gatskop gekry. Dit het ook nie meer visie nie, want die voorruit is aan vlarde. Wat ‘n droewige gesig. Ons begin aflaai. Elke soort metaal kry sy eie tuiste, koper hier, alimunium daar, brons in ‘n drom wat geel gemerk is. Elke keer na ‘n spesifieke metaal afgelaai is, moet die voertuig terug skaal toe om die gewig van ‘n metaal te bepaal. Uit die aard van die saak verskil metale se pryse, Binne my aanvanklike beeld van skrootchaos, ontluik daar ‘n onderliggende nougesette en presiese ordeningsproses. Die aflaai self vorm ‘n ritmiese proses, ‘n stille doelgerigtheid in kontras met die ruwwe aard van die omgewing. ‘n Indruk tref my. Hierdie versameling van skroot, in teenstelling met wat meeste mense as afval sal beskou, word met metodologiese sorg hanteer. Dit is nie net ‘n stortingsarea nie, dit is ‘n sorteringsterrein waar die oorblyfsels van industrieële komponente nuwe waarde vind – elke item word sorgvuldig uitgesoek, geweeg, geprys, en uiteindelik herwin tot nuwe bruikbaarheid. Die laaste item word afgelaai. Ek word verwys na die betaalkantoor en stap die trappe op. ‘n Vriendelike dame groet my. Haar naam is Elsabe. Sy is druk besig om al die berekeninge te doen. Ek vra: “Elsabe, kry ek darem genoeg geld om ‘n draai by die Spur te maak?” “Ja oom, en genoeg vir ‘n voorgereg ook”  Ek ry weg met kontant in die hand en met ‘n dieper begrip van ‘n nuwe wêreld wat ek nie voorheen geken het nie. Dit wat aanvanklik as ‘n eenvoudige taak begin het, het voortgevloei in ‘n begripvolle blik op ‘n nywerheid wat ons moderne bestaan op ‘n positiewe wyse rugsteun. Agter elke hoop rommel is daar in werklikheid ‘n storie.
