Do banks inform HMRC of income

RIFT Roundup: The Essentials

• UK banks and building societies report information about interest paid or credited to HMRC each year.

• Your bank does not routinely send HMRC a copy of every transaction in your current account.

• Salary information normally reaches HMRC through your employer’s PAYE payroll reporting, rather than because your bank sees your salary arrive.

• HMRC has legal powers to require specific bank information where the statutory conditions are met.

• Overseas financial accounts and digital selling platforms (like eBay, Etsy, or Vinted) can be subject to separate automatic reporting rules.

UK banks do provide HMRC with some financial information. That does not mean HMRC receives a live feed of everything you buy, every transfer you make or your complete transaction history.

The information HMRC receives depends on the type of account, the type of income and the legal reporting route involved.

Here’s what UK taxpayers need to know.

What do UK banks automatically report to HMRC?

HMRC requires UK banks and building societies to submit annual information about interest paid or credited to reportable customers.

This requirement sits under Schedule 23 of the Finance Act 2011.

The information submitted can include details used to identify the customer and account, together with the gross interest paid or credited during the reporting period.

HMRC uses this information for purposes including:

·       pre-populating tax records

·       PAYE coding

·       tax calculations

·       checking whether Self Assessment returns are complete and accurate

This reporting happens whether or not you ultimately owe tax on the interest.

Does HMRC know how much savings interest you earn?

In many cases, yes.

Banks report relevant savings interest to HMRC annually.

For the 2026/27 tax year, the Personal Savings Allowance remains:

·       £1,000 for basic-rate taxpayers

·       £500 for higher-rate taxpayers

·       £0 for additional-rate taxpayers

There is also a separate starting rate for savings for some people with lower levels of other income.

If tax is due on your savings income, HMRC may be able to collect it through your tax code or it may need to be included in Self Assessment, depending on your circumstances.

Do banks send HMRC every transaction?

Banks do not routinely submit your complete transaction history to HMRC as part of the standard annual bank-interest return.

That means the ordinary domestic interest reporting process is different from HMRC receiving a live list of:

• your supermarket spending

• cash withdrawals

• transfers between your own accounts

• money sent by friends or relatives

• every Direct Debit

• your day-to-day card purchases

"There is a huge misconception that HMRC is secretly watching your bank account 24/7. In reality, banks only send over aggregate reports on things like savings interest unless HMRC launches a formal compliance check. As long as your Self Assessment accurately reflects your income and allowable expenses, increased digital reporting isn't something to fear - it's just HMRC ensuring a fair playing field." -  Jan Post, RIFT Founder

HMRC can obtain more detailed information where it has a lawful basis to do so, but that uses different information powers.

Does my bank tell HMRC about my salary?

Your employer normally reports salary, Income Tax and other payroll information directly to HMRC through PAYE Real Time Information.

The fact that your salary also appears as a deposit in your bank account does not mean your bank is separately reporting that deposit as employment income under the routine bank-interest return.

HMRC can therefore already have detailed salary information without needing your current-account transaction history.

What about money transferred by friends or family?

A bank transfer does not become taxable income simply because money reaches your account.

What matters is why you received the money.

For example, a transfer could represent:

• repayment of money you lent someone

• someone’s share of a household bill

• a genuine gift

• payment for freelance work

• business sales

• rental income

Those payments can have very different tax treatments.

Using a sensible payment reference can help you understand your own records later, but a bank-transfer label by itself does not prove the tax treatment.

If a payment could be relevant to your tax affairs, keep the underlying evidence as well.

Can HMRC ask a bank for your statements?

Yes, HMRC has statutory information powers.

One of those powers is a Financial Institution Notice, or FIN.

A FIN can require a financial institution to provide information that is reasonably required to check a known taxpayer’s tax position or for certain tax-debt purposes.

HMRC’s current guidance says a FIN does not require the taxpayer’s prior agreement or approval from the tax tribunal before it is sent to the financial institution.

There are still safeguards.

An authorised HMRC officer must approve the FIN, and HMRC’s own guidance says reasonable steps should normally be taken to obtain information directly from the taxpayer where appropriate.

Where HMRC is seeking bank statements from an account on which the taxpayer is a signatory, its manual says the taxpayer should normally be asked to obtain them first unless there is a reason to take another route.

The taxpayer normally receives a copy of a FIN. In certain circumstances, HMRC can apply to the tribunal so that this requirement does not apply where giving notice could prejudice the assessment or collection of tax.

Can HMRC see your bank account whenever it wants?

HMRC does not have general live login access to customers’ bank accounts.

Its routine information feeds and its formal information powers are separate things.

Routine annual bank reporting gives HMRC specified information such as interest.

A request for more detailed bank records has to operate through the relevant legal powers and conditions.

What happens with overseas bank accounts?

Separate international information-sharing rules apply.

Under the Common Reporting Standard and other Automatic Exchange of Information arrangements, financial institutions can report details about accounts held by people who are tax resident in another participating jurisdiction.

If you’re UK tax resident and hold a reportable account abroad, the overseas tax authority can pass information to HMRC.

Depending on the account, this information can include:

• your identifying details

• account number

• account balance or value

• interest

• dividends

• certain other income or proceeds

The Common Reporting Standard rules were expanded from 1 January 2026.

Holding an overseas account is not automatically a tax problem. The important point is that any income or gains that need to be declared under UK tax rules are reported correctly.

Do eBay, Vinted and other online platforms report to HMRC?

Digital-platform reporting is separate from bank reporting.

UK platform operators can be required to collect and report information about sellers to HMRC.

For someone selling goods, the current reporting rules provide an exclusion where they meet both of these conditions in the calendar year:

• fewer than 30 sales

• total proceeds of less than €2,000, roughly £1,700 depending on the exchange rate

If either limit is exceeded, the platform may need to report the seller.

This is a platform-reporting threshold. It does not determine whether the seller owes tax.

Tax depends on what the activity actually is.

For example, selling unwanted personal possessions is different from buying or making products with the intention of selling them for profit.

For genuine trading activity, the separate trading allowance is generally £1,000 of gross trading income per tax year, subject to the rules and exceptions.

Platforms also report certain services and property-related activities, where different seller-reporting rules can apply.

Does platform reporting mean HMRC thinks you owe tax?

No.

HMRC’s own guidance makes clear that a platform reporting your details does not automatically mean tax is due.

The information gives HMRC another source against which tax records can be checked.

If you have taxable trading, rental or other income, you remain responsible for meeting the normal reporting requirements whether or not a bank or platform has separately sent information to HMRC.

How should you keep your records?

Keep records that explain the substance of money you receive.

Depending on your circumstances, that might include:

• invoices

• receipts

• sales records

• contracts

• platform statements

• rental records

• evidence of reimbursed expenses

• records supporting genuine personal transfers

• bank statements where they form part of your business records

Good records make it easier to complete an accurate return and respond if HMRC asks how a figure was calculated.

How HMRC receives your financial data

What does this mean if you’re self-employed? 

If you’re self-employed, HMRC expects you to declare all taxable income accurately. 

Business bank accounts are more likely to be reviewed during compliance checks. Large unexplained deposits may prompt questions if they don’t align with what has been reported. 

Good habits make all the difference: 

• Use a separate business account

• Keep clear records

• Log expenses accurately

• File returns on time

Do banks inform HMRC of income FAQs

Does my bank tell HMRC how much money I have?

The standard UK bank-interest return is mainly concerned with reportable interest and customer or account details rather than automatically providing HMRC with your full day-to-day account history.

Other regimes can be different. International Automatic Exchange of Information reporting can include the balance or value of reportable financial accounts.

Does HMRC know about my savings account?

UK banks and building societies generally report interest paid to reportable UK customers. That can allow HMRC to match savings income to your tax record.

Can HMRC get my bank statements?

Yes, where its statutory information powers and the relevant conditions are met. A Financial Institution Notice is one mechanism HMRC can use.

Are transfers between family members taxable?

A transfer is not taxable simply because it appears in a bank account. Its tax treatment depends on what the payment represents.

Does selling on Vinted or eBay mean I need a tax return?

Not automatically. Selling personal possessions is different from trading. Platform reporting thresholds are also separate from tax thresholds.

Will HMRC know if I have a foreign account?

HMRC receives information about many reportable overseas accounts through international Automatic Exchange of Information arrangements. UK residents remain responsible for correctly declaring taxable foreign income and gains.

The key point

HMRC receives far more financial information than it did in the past, but different information arrives through different legal and reporting systems.

Banks report savings interest. Employers report payroll. Digital platforms can report sellers. Overseas tax authorities exchange certain financial-account information.

Your responsibility remains the same: understand which income or gains are taxable, keep appropriate records and report what the tax rules require.

If you’re unsure whether income should have been included on a tax return, check the relevant HMRC guidance or get qualified tax advice before making assumptions about what HMRC can already see.
