On 19 March, the Bank of England cut the base rate for the second time in a week, reducing it to 0.1%.
In response, HMRC had decreased the interest charge on underpaid quarterly corporation tax instalment payments to 1.25% from 1.75%.
Interest paid on overpaid quarterly instalments and on early corporation tax payments is 0.5% – unchanged since September 2009.
All other interest rates for over and underpaid tax are the same.
