The benefits of replenishing your ISA earlier in the year can have a significant impact on the level of wealth you accumulate over time.
More time to grow
The main benefit of an ISA is that you can shelter £20,000 a year from tax, or £40,000 for a couple. Yet when we invest, we also do so with the intention that our capital will grow. More time in the market means more potential for growth in a rising market.
In the following illustration we highlight the benefits of accumulating tax savings over time by using an ISA as opposed to a taxable general investment account (‘GIA’), as well as the additional growth potential from investing earlier rather than later.
We consider the potential projected outcomes at the end of five years when £20,000 is invested each year in the Netwealth Risk Level 6 portfolio, achieving our assumed average return. When investing with a GIA at a higher rate of tax – by investing at the start of each year instead of the end of each year – the portfolio benefits from compounded growth for a longer period of time and results in a higher ending value.
By using an ISA and sheltering the portfolio from taxation, the portfolio achieves even higher ending values with the best outcome from using an ISA and investing at the start of each year. Of course, there is no guarantee that stock markets will grow over any given period, but over the long term, they have proven to be the best way to outperform inflation.
Gain peace of mind quicker and avoid the last-minute agitation of organising your finances at the end of the tax year – including niggling paperwork. Also, by replenishing your ISA sooner you are less likely to forget to check it off your to-do list.
Use it or lose it
When you do forget, there is no second chance. Your ISA allowance is not cumulative, so every year you must use it or forgo its benefit.
When we are flustered, or in a hurry, we are more likely to allow behavioural biases to affect our investments. These biases occur because we prefer to take shortcuts when making decisions, so for example, we may be prone to herd behaviour, overconfidence or simply suffer from inertia.
You may prefer to invest a lump sum at the start of the year but investing monthly is effective, too, if you don’t have the full amount to hand. This method captures the benefits of time for capital to grow and minimising hassle, but it also lets you use what is known as pound cost averaging. This averages the price you pay for an investment over time and helps to smooth out the effects of market volatility.
Deploy the wonders of compounding sooner
More time invested allows your returns to earn better returns – the key factor of compounding, which Albert Einstein reputedly labelled as the eighth wonder of the world. The sooner you allow your ISA wealth to compound the better.
Extra Netwealth benefits
Netwealth clients have two more meaningful ways to benefit from replenishing their ISA earlier in the year:
Naturally, the earlier in the year you top up your ISA the more time you have for the benefits to accrue. Yet even if a few months have passed you can still make a considerable difference to the value of your tax-free savings.
Please remember that when investing your capital is at risk.
