State Pension & Private Pension

I have a Private Pension which began to pay out two years ago, and the provider deducts the tax each month before payment.
My State Pension began in January 2024
Your website states that: "Your private pension provider will usually take off any tax you owe before they pay you. This includes any tax you owe on your State Pension" Tax when you get a pension: How your tax is paid 
I have now received my P60 from the private pension provider which gives the total amount of tax paid for year ending 05 April 2025, but it provides no breakdown of the tax paid on the private and state pensions.
How do I know that the private pension provider has deducted the correct amount of tax for the state pension?

Hi Anth
Your state pension is included as a deduction in your tax code and that tax code is applied against your private pension. The cumulative amount of tax is then deducted. There is no split on tax deducted as a result.
You are quite correct in referring to the guidance at:

• Tax when you get a pension: How your tax is paid

You should also review:

• Paid too much or too little tax? Here’s what to do 

​​​​​​​You can also use the HMRC tax checker to review the tax deducted on your private pension when including both sources of income. 
Changes that you wish to make to your tax code or details of your income can be found through:
• your personal tax account or
• the official HMRC app 
Thank you
