When you reach your State Pension age, you don’t have to claim your State Pension straight away. Your State Pension age is the earliest age you can start receiving your State Pension. Check your State Pension age on the GOV.UK website
You can delay (defer) claiming it. In return, when you do decide to take your State Pension – if you've put off claiming it for at least nine weeks – you could increase the payments you get when you decide to claim it.
Be aware that different terms apply, depending on when you reach your State Pension age .
Your State Pension will increase by 1% for every nine weeks you put off claiming. This works out at just under 5.8% for every full year you put off claiming.
The new State Pension, and any extra State Pension, are both taxable income.
If you deferred your State Pension before 6 April 2016, you will continue to be treated under the old rules. This means you’ll still be entitled to take a lump sum or increased pension.
