I was entitled to State Pension from end September 2023 and in the tax year to 5/4/24 received payments for a 2 week period and six 4 week periods. The last receipt falling in the tax year was received on 21 March 2024. My tax charge for 23/24 has been based on an additional 2 weeks to 5 April, even though these were not actually received until 18 April. DWP have advised me that for taxable income purposs HMRC take the weekly amount and multiply by number of weeks from entitlement to 5 April and not on actual receipts. This means I have been taxed on 2 weeks of Pension which were not received. Can HMRC sort out this anomaly
