How much of my pension can I get at 55?
Technically 100% of it. Doing so would incur a severe tax charge as only 25% of those funds are tax free. Therefore it is not advisable for everyone.
The first 25% is tax free but the remainder will be taxed at your highest tax boundary. What makes sense is to take the tax free amount if you need it. If not take what you need when you need it, which is part of the beauty of the new rules brought in. Your pension can supplement your income while you are still working.
The answer to this also depends on where your pension is held. In the flexi-access drawdown you could access all of your pension, there’s parameters and regulation around it about how much you can take tax free. But ultimately you have the opportunity to access all of your funds.
