Workplace pension contribs vs personal savings allowance

Let's say you earn gross £60,000. This makes you a higher rate tax payer. As a result your personal savings allowance will be £500 -- any savings interest above that level will be taxed, at 40%. However, what if you contribute £1,000 a month to a workplace pension through auto-enrollment? Employee contributions, I mean. Well then is your 'effective taxable' income reduced by £12,000 to £48,000 and are you now no longer a higher rate tax payer, and does your savings allowance increase to £1000? TLDR: Will increasing my workplace pension contributions to increase my personal savings allowance?

Hi
You are correct.

Hi, Am I right to understand from this that if I am to make additional pensions contributions to my workplace pension scheme which in total over a tax year are greater than my income in the higher rate tax band (over £50,271), then the interest from my savings would be subject to the basic rate personal savings allowance of £1,000 not the higher rate personal savings allowance of £500?

Hi,
If your adjusted net income means you are not a higher rate taxpayer then you will receive the full £1000 savings allowance.
Personal Allowances: adjusted net income
Thank you.
