Can I contribute more in SIPP (I have not use the pension allowance in previous 3 years)?

I have not use the pension allowance in previous 3 years. Is it true that I can use the pension allowance in this year and contribute more ? i.e. the maximum for contribute in SIPP is £2880 a year for annual salary < £3600, is it true that the contribution to SIPP this year can be £2880 x 4 = £11520, using the previous 3 years allowance plus this year's allowance?

Hi YY WONG,
The tax relief would still only be limited to your earnings.
The three years you are referring to is for unused allowance, so that you do not have a pension tax charge as you have exceeded the annual allowance of 40k
Check if you have unused annual allowances on your pension savings
Thank you.
