For a start, automatic enrolment is intended to make it easier for you to invest for your retirement. Rather than you having to take steps to join a pension, most employees will be signed up as a matter of course.
But perhaps the biggest benefit is that if you’re automatically enrolled, your employer will contribute to your pension as well as you.
Whether you are automatically enrolled, or you choose to opt in or join, you will benefit from tax relief from the government on any contribution you make. For every 80p you pay into your pension, the government adds 20p in tax relief, increasing it to a total contribution of £1. So, if you paid £80 into your pension each month, the government would boost it to £100. Your employer may have opted for salary sacrifice, or exchange. This is an arrangement between you and your employer. Please contact your employer for more information.
Please note that tax rules may change and your tax treatment will depend on your personal circumstances. The value of your investments can go down as well as up, and you may get back less than has been invested.
Staying in or opting out - you're in control
If you're auto-enrolled you can opt out if you want to. If you do so within a month, any contributions already paid will be refunded. If you opt out later, this money will stay in your pension.
If you opt out, you will miss out on employer contributions and any tax relief from the government. However, you may be able to change your mind and opt back in.
If you stay opted out, your employer will normally put you back into the pension in around three years. But you can again choose whether to opt out. Remember that the sooner you join, the better your chance of a more comfortable retirement.
