Lloyds Bank is asking you to confirm your tax residency because UK law requires every bank to identify where its account holders pay tax and pass that information to HMRC. The request usually arrives as a letter with a self-certification form, and you have 60 days from the date on the letter to send it back. Returning the form promptly is the entire task; ignoring it causes real problems.
The Law Behind the Request
Two international frameworks sit behind the letter. The Common Reporting Standard (CRS), developed by the OECD and signed by more than 120 jurisdictions, requires financial institutions to identify customers who are tax resident in another participating country and share their account details with the local tax authority, which passes the information on. The Foreign Account Tax Compliance Act (FATCA) is a US law that requires foreign banks to identify and report accounts held by US persons; the IRS can impose a 30 percent withholding tax on US-source payments to any institution that fails to comply.1Internal Revenue Service. Summary of Key FATCA Provisions
Under both rules, Lloyds reports account information to HMRC. If you are tax resident in another country, HMRC passes the data to the tax authority there.2Lloyds Bank. Common Reporting Standard FAQs The bank is not auditing you or questioning your tax affairs. It is collecting the information it is legally required to collect.
One point of confusion worth clearing up: tax residency is not the same as nationality or immigration status. Each country sets its own rules, and it is possible to be tax resident in more than one place at once. The form asks you to declare every country where you are tax resident under that country’s own domestic rules.
What the Form Asks For
The self-certification form is short, but each field needs to be right. You will be asked for:
- Your full legal name, exactly as it appears on your government-issued ID
- Your date of birth
- Your current residential address (your permanent address, not a correspondence address)
- Every country where you are tax resident
- A Tax Identification Number (TIN) for each of those countries3Lloyds Bank. Common Reporting Standard
The TIN is where people get stuck, because different countries call it different things. If you are UK tax resident, your TIN is your National Insurance number.4GOV.UK. IEIM902330 – Tax Identification Number (TIN) You can find it on your payslip, your P60, or through your personal tax account on GOV.UK.5GOV.UK. Find Your National Insurance Number If you are a US citizen or US tax resident, your TIN is your Social Security Number or Employer Identification Number.3Lloyds Bank. Common Reporting Standard
If your country of tax residence does not issue TINs, or you have been unable to obtain one, the form asks you to pick a reason code. The standard options are that the country does not issue TINs, that you have been unable to obtain one, or that the jurisdiction does not require financial institutions to collect it. Choose the one that fits and give a brief explanation if asked.
How to Send It Back
Lloyds posts the form with a prepaid return envelope. You fill it in, sign it, and mail it back. The bank does not currently accept this form through online banking or the mobile app, because an original signature on paper is required.2Lloyds Bank. Common Reporting Standard FAQs Keep a photocopy for your records before you post it.
The 60-day deadline is printed on the letter. If that window has already passed, send the form back anyway. Lloyds still accepts late returns, and a late form is far better than no form.2Lloyds Bank. Common Reporting Standard FAQs After the bank receives the form, it checks the information against your existing account details. If anything doesn’t match, expect a follow-up letter asking you to clarify.
What Happens If You Don’t Respond
Ignoring the request does not make it go away. If Lloyds has no certification from you, it is required to treat you as a reportable person based on whatever address or nationality indicators it already holds. HMRC then receives your account information and may forward it to a foreign tax authority, even if you are in fact only UK tax resident and have no foreign tax obligations at all.6GOV.UK. Automatic Exchange of Information if You Have an Account
The bank can also restrict your account. Under CRS and FATCA rules, financial institutions may decline transactions, freeze services, or close accounts belonging to customers who refuse to certify their status. For many accounts, the compliance risk of keeping an uncertified account open outweighs the value of the relationship. A one-page form is far less disruptive than a frozen account or a letter from a tax office in a country you briefly lived in years ago.
If Your Circumstances Change
The self-certification is not a one-off. If you move abroad, change your tax residency, or change your address in a way that affects your tax status, Lloyds requires you to tell them within 30 days.7Lloyds Bank. Common Reporting Standard (CRS) The bank may send you a new form, or you may need to contact them to request one. Updating promptly means the next report Lloyds sends reflects your actual situation rather than stale information that could prompt an inquiry from a foreign tax authority.
Extra Step If You Are a US Citizen or Green Card Holder
US persons face an additional layer. If you are a US citizen or green card holder with a Lloyds account, the bank reports your account to HMRC under both CRS and FATCA, and HMRC passes that information to the IRS. This applies no matter where you live. A US citizen who has been in London for twenty years still has US tax obligations on worldwide income.
Lloyds may ask you to complete a Form W-9 if you are a US person, or a Form W-8BEN if you are not a US person but receive US-source income. The W-9 certifies your status as a US taxpayer and provides your Social Security Number. The W-8BEN certifies that you are a foreign person for US tax purposes and may entitle you to a reduced withholding rate under a tax treaty.8Internal Revenue Service. Instructions for Form W-8BEN A common mistake is picking the wrong form. If you are a US citizen or permanent resident, the W-8BEN does not apply to you; you need the W-9.
