Obtaining BBSI from HMRC

bucksman

With a few accounts in banks and building societies, I was hoping to check that my reconciliation is accurate, and the same total that is sent to HMRC by banks and building societies.  Is the information used by HMRC available?  I reviewed my tax records and cannot see it; I only see the numbers I submitted on the SA form. Thank you in advance for your guidance.

Presumably you are after the details reported for 2024/25?

If so then there isn't any way that I'm aware of that you can see those on your online account. 

The best you could get is the estimate being used for the current tax year.  Which may be based on what was reported for 2024/25 but is just a single total, not a breakdown by individual bank account.

You will have to ask HMRC to send you the details you want in the post.

Thank you for your quick response. Yes, I am looking at 2024/25.  It is surprising this is not available in the user app/account, a letter in the post ...how 20th century

I got a P800 notice last week, and it included my total bank interest for the year (shown as one combined figure rather than broken down by each bank).

Just so you know, HMRC doesn’t issue a P800 every year,  you only get one if they think you’ve overpaid or underpaid tax through PAYE, and only if you didn’t file a Self Assessment for that year.

Mine showed that I’d overpaid by £50, which I already expected because I was taxed on my July 2024 wages but was then made redundant, so I ended up paying too much.

It might be worth asking HMRC whether they’ve produced a P800 for you, or simply what bank interest figure they have recorded. One thing to note: HMRC rounds figures down to the nearest pound. So if your actual interest was £847.87, the P800 will show £847. The only figure they use to the exact penny is your “real-time” wage information from your employer.

Best to just give them a ring (first thing in the morning if you want to get through quickly). 

They should be able to give you a total figure and hopefully it will be the same as yours. If not, and it is a helpful advisor like the ones I have experienced in the past, they may go through the figures account by account until you find the reason for the discrepancy.

Good luck.

It's not available because you are not the intended recipient of the information. It is for internal use by HMRC. But they will share it with you if you request it. A bit like a DSAR.

Note that the figures you submit in SA can validly differ from the BBSI return information, and it is your figures that will be used to calculate your tax liability.

I am glad I requested a print out of the untaxed interest by account from HMRC, in their calculations there are many incorrect high value Estimated figures for my 2024/25 based on the previous tax year, but these accounts were no longer paying market rates and I had either emptied them, or closed them (or they were a 1 year duration) before the 24/25 tax year. They over estimated the amount of untaxed interest by over 10K.

When did you request the figures? I would have thought by this time of year HMRC should have accurate figures for 24/25 (apart from potential discrepancies from non-accessible interest in multi year fixed accounts).

I agree with the OP that it would be nice to have all this info available through your online tax account. I really don't fancy having all my account interest information sent to me by post.

And had they done anything with them? 

Did you ask for the breakdown as you had received a P800 or PA302 which was wrong?

The request was sent in a letter dated 3rd of October 2025. I had asked HMRC back in May of this year and they said they were unable to provide it before September as institutions do not supply the information before then (this could have been someone just wanting to close this enquiry without supplying the information of course).
The problem seems to be they don't anticipate someone moving money between accounts as often as I do to chase good rates, and so they assume previous years bank accounts are still active and have just been not reported to them.

Still waiting here on them to finalise my BBSI for 24/25 - usually it's done by October but seems to be getting later and later each year.

I've noticed this too - more often than not, they've carried over actual amounts of interest earned in fixed term accounts as estimates for subsequent years (sometimes multiple years, even after already telling them that account had closed).

What's worked best for me is calling them once a year to set my expected interest for the current year to be zero, then I wait for them to get the reporting info from the banks and then settle up after. Then I know that I'm paying the right amount, rather than it being based off their (often wrong) estimates. Had it confirmed on two occasions that they're fine doing this.
