HMRC over estimate of untaxed interest

Eldi_Dos

If you have had issues with over estimated interest it may pay you to check Tax year 2025/2026 figures as it looks like over estimates are rolled over into that year.

Update - again thank you for your help - I managed to navigate and update the relevant incorrect estimates. 

However, I noticed I apparently owe tax from 23/24 due to untaxed interest (never received any notification of this). The interest figure they have is nowhere near mine. There is nowhere to amend this, so I had to call them - 80minutes to get through! They are going to send me their breakdown and have advised I will have so submit my evidence if I want to dispute it - I’m guessing this will not be a quick process!

This included details of my untaxed interest and how much I owed them.

Do you mean that you could see the breakdown of interest paid by each bank/building society/other? Because I had no such breakdown in my online data, I had to ring them up and they went through the list on the phone while I checked off each one against my own records (the alternative was to send me the list by post, but that would have taken at least 10 days). 

As it turns out the total was less than it should have been as for some reason Chase had not submitted any figures to HMRC, although I don't know if that was just for me or for everyone. I'm waiting for them to respond to my complaint now.

In case anyone has been waiting with bated breath for an update on this, here's the latest.

Chase responded to my complaint after a few weeks (well within the 8 weeks) to confirm that they did submit the figures to HMRC, providing me with the annual interest statements and crediting me with a £50 goodwill payment. Unfortunately what they gave me didn't shed any light on whether the fault lay with Chase or HMRC, so I submitted a SAR (or a Right to Access Request as they refer to it) for the actual data that they submitted to HMRC.

That took a couple of weeks but today they gave me access to a Secure Content Delivery website which allowed me to download a spreadsheet with two rows, one for each of the accounts that interest had been paid on. That revealed that my National Insurance Number was missing from both records, which is presumably why HMRC were unable to allocate it to my tax record.

It's a while since I opened my first Chase account so I can't remember whether it required my NINO (anyone who has opened one recently may know) but I would have thought it would be needed, so I've asked Chase to extablish whether they ever had it or if they never asked for it, so that they can resubmit my data to HMRC for 2023/4 and also ensure it's there for the 2024/5 submission, and future years.

I've no idea whether it's an isolated incident that only affects me or if it's more widespread affecting some or all Chase customers. If anyone else has asked HMRC for a breakdown of 2023/4 interest that should include Chase it might be helpful to know if it was present or not.

I don't believe there is a requirement for a bank or building society to obtain your National Insurance number unless you are opening an ISA.

You might well be right, but given that since the change so that any account paying interest has to be reported to HMRC you might have thought that NINO would be part of what HMRC require the bank to submit as that's really the only thing that individually identifies a taxpayer. And clearly it is one of the items that Chase expect to submit as it's one of the fields in the subnmission record, so it would surely make sense for them to ask for it. Anyway, we'll see what they say when they respond to my email, and I'm also planning to call HMRC to ask them how they can allocate a submission without a NINO (on a day when I'm able to phone before 8am).

They enter your name and address into their computer and look for a hit. 

So if there are two people with the same name at an address which one do they allocate the interest to? That's why NINO is the obvious means of identification, as I've already pointed out.

It's obvious but no legal requirement to provide it (except for ISA's). I would imagine GDPR would prevent banks routinely asking for this information as they do not need it to fulfill the purpose of providing a bank account.

In the scenario you describe I imagine the date of birth might be provided as part of the data and increase the chances of a match.

Interest reports to HMRC will not include your NINO and the accuracy of what is included in your tax calculation is dependant on HMRC matching the data provided to your tax record, which will not always be 100% accurate. So your berating of Chase is probably unjustified on this occasion.

I haven't berated anybody, I've asked Chase to establish whether they do have my NINO already but didn't include it, or if they need me to provide it now. If neither is the case then they can say that, but given that there is a space for NINO on the submission record either they supply it in at least some cases or HMRC expect it where it's available (and let's face it, they managed to match up my interest from every other banks, so something has gone wrong).

So you have provided your NINO to every bank you are with? Fairly unique if you have.

I've no idea whether I have or haven't, but I do know that whatever every bank submitted to HMRC it was sufficient for them to allocate the interest to my tax account, except for Chase.

I've just got off the phone with HMRC, their position aligns with the majority fo posters on here that NINO is not mandatory in submission, but the agent I spoke to felt that most banks did provide it. They have now added the amount I received and reissued my Simple Assessment.

What I may do now is submit a FOI request to HMRC to request the data submitted by all the banks just to establish which ones do include NINO, and for any that don't whether there is something in their data that makes reconciliation successful that is missing in the Chase submission.

Edit: It's actually a SAR that I've had to submit to HMRC using their web form.

Wouldn’t Data Protection preclude them from using it, or from it being revealed?

Who is ‘them’?

HMRC would be searching their own records so who would they be revealing it to?

No different to tracing record from NINO

No different to tracing record from NINO

There is no reason for a bank or building society to collect your National Insurance number in the first place, unless you are opening an ISA. So the DPA awould prevent them doing so. If you close an ISA they can retain your NINO for a reasonable timescale, related to answering queries about your ISA, but no longer.

If regulations change then providers would be able to collect your NINO but it’s not the data that HMRC currently use for matching reported non-ISA savings to the individual.

In case anyone has been waiting with bated breath for an update on this, here's the latest.

Chase responded to my complaint after a few weeks (well within the 8 weeks) to confirm that they did submit the figures to HMRC, providing me with the annual interest statements and crediting me with a £50 goodwill payment. Unfortunately what they gave me didn't shed any light on whether the fault lay with Chase or HMRC, so I submitted a SAR (or a Right to Access Request as they refer to it) for the actual data that they submitted to HMRC.

That took a couple of weeks but today they gave me access to a Secure Content Delivery website which allowed me to download a spreadsheet with two rows, one for each of the accounts that interest had been paid on. That revealed that my National Insurance Number was missing from both records, which is presumably why HMRC were unable to allocate it to my tax record.

It's a while since I opened my first Chase account so I can't remember whether it required my NINO (anyone who has opened one recently may know) but I would have thought it would be needed, so I've asked Chase to extablish whether they ever had it or if they never asked for it, so that they can resubmit my data to HMRC for 2023/4 and also ensure it's there for the 2024/5 submission, and future years.

I've no idea whether it's an isolated incident that only affects me or if it's more widespread affecting some or all Chase customers. If anyone else has asked HMRC for a breakdown of 2023/4 interest that should include Chase it might be helpful to know if it was present or not.

I don't believe there is a requirement for a bank or building society to obtain your National Insurance number unless you are opening an ISA.

You might well be right, but given that since the change so that any account paying interest has to be reported to HMRC you might have thought that NINO would be part of what HMRC require the bank to submit as that's really the only thing that individually identifies a taxpayer. And clearly it is one of the items that Chase expect to submit as it's one of the fields in the subnmission record, so it would surely make sense for them to ask for it. Anyway, we'll see what they say when they respond to my email, and I'm also planning to call HMRC to ask them how they can allocate a submission without a NINO (on a day when I'm able to phone before 8am).

They enter your name and address into their computer and look for a hit. 

Wouldn’t Data Protection preclude them from using it, or from it being revealed?

Who is ‘them’?

HMRC would be searching their own records so who would they be revealing it to?

No different to tracing record from NINO

By "them" I meant banks or building societies.

I thought that was what you meant, but I possibly misunderstood your post.

I’m in a similar boat, it is hard to speak to anyone and my personal allowance before I pay tax has been reduced by around £500 and my tax code has changed

is that how they claw back the tax?

my ISA is full and I can’t pay anymore into works pension.
