Last updated: 28 July 2026
There is no maximum amount of money that a person can legally hold in a UK bank account without being taxed. A bank balance is not normally taxed simply because it is large.
What matters for Income Tax is usually:
- The interest generated by the money
- The person’s total taxable income
- Which savings allowances are available
- Where the money originally came from
- Whether the person receives means-tested benefits
For the 2026–27 tax year, a basic-rate taxpayer can normally receive up to £1,000 of savings interest tax-free through the Personal Savings Allowance. The allowance is £500 for a higher-rate taxpayer and £0 for an additional-rate taxpayer. People with low non-savings income may also benefit from the Personal Allowance and the starting rate for savings.
Direct answer: There is no tax-free bank balance limit in the UK. A person could have £5,000, £50,000 or £500,000 in an account without the balance itself attracting Income Tax. Tax may become due on the interest, income or gains connected with that money.
This information is general guidance rather than personal tax advice. Tax treatment depends on individual circumstances, residence status and the source of the funds.
What Is the Tax-Free Bank Balance Limit in the UK?
The UK does not impose Income Tax according to the amount shown on a bank statement.
Depositing money that has already been taxed does not normally cause it to be taxed again. For example, moving £30,000 from one savings account to another does not create £30,000 of taxable income.
However, the source of a deposit may have separate tax consequences:
| Source of money | Possible tax treatment |
| Employment income | Usually taxed through PAYE |
| Self-employed profit | Normally reported through Self Assessment |
| Savings interest | May be taxable above available allowances |
| Sale of shares or property | Capital Gains Tax may apply to a gain |
| Inheritance | Usually no tax is payable by the recipient when it is received |
| Cash gift | Normally not treated as the recipient’s income, although Inheritance Tax rules may affect the donor’s estate |
| ISA withdrawal | Normally tax-free |
| Business takings | Must be included in the business’s taxable records |
The fact that money has reached a bank account does not, by itself, determine whether tax is due.
What Are the Savings Tax Allowances for 2026–27?
Three main allowances can protect savings interest from Income Tax:
| Allowance | 2026–27 amount | Who may use it? |
| Personal Allowance | Up to £12,570 | Most people, subject to income limits |
| Starting rate for savings | Up to £5,000 | People with relatively low non-savings income |
| Personal Savings Allowance | £1,000, £500 or £0 | Depends on the person’s Income Tax band |
| ISA allowance | £20,000 of new subscriptions | Eligible ISA savers |
The standard Personal Allowance remains £12,570 for 2026–27. It is reduced by £1 for every £2 of adjusted net income above £100,000 and is normally removed completely once adjusted net income reaches £125,140.
These allowances apply to interest rather than the underlying balance.
What Is the Personal Savings Allowance?
The Personal Savings Allowance, commonly called the PSA, allows many taxpayers to receive a limited amount of savings interest at a 0% tax rate.
For 2026–27, the limits are:
| Taxpayer’s band | Personal Savings Allowance |
| Basic-rate taxpayer | £1,000 |
| Higher-rate taxpayer | £500 |
| Additional-rate taxpayer | £0 |
A person’s tax band is determined after adding savings interest to their other taxable income. Interest can therefore push someone into a higher band and reduce the PSA available to them.
Scottish taxpayers pay Scottish rates on earnings, pensions and most other non-savings income, but savings interest is subject to UK-wide savings tax rules. Because Scottish income bands differ, taxpayers in Scotland should use HMRC’s calculation service or obtain professional advice where income falls close to a band boundary.
How Much Can Be Kept in Savings Before Interest Becomes Taxable?
The answer depends on the account’s interest rate.
The following figures show approximately how much could be held before the account generates interest equal to the PSA. They assume the interest rate remains unchanged for a full year and that no other allowance is available.
| Annual interest rate | Balance producing £1,000 interest | Balance producing £500 interest |
| 3% | £33,333 | £16,667 |
| 4% | £25,000 | £12,500 |
| 5% | £20,000 | £10,000 |
Therefore:
- A basic-rate taxpayer earning 5% could generate approximately £1,000 of interest from £20,000.
- A higher-rate taxpayer earning 5% could generate approximately £500 of interest from £10,000.
- An additional-rate taxpayer does not receive a PSA for interest held outside tax-free accounts.
These are illustrative calculations, not fixed tax-free balance limits. Variable rates, bonuses, monthly interest, compounding and other income can change the final position.
The basic calculation is:
Tax-free balance estimate = available interest allowance ÷ annual interest rate
For example:
£1,000 ÷ 0.04 = £25,000

What Is the Starting Rate for Savings?
People with low income may receive up to £5,000 of savings interest at the 0% starting rate.
The full £5,000 starting-rate band is generally available where non-savings income does not exceed the £12,570 Personal Allowance. It is reduced by £1 for every £1 of non-savings income above the Personal Allowance.
Once relevant non-savings income reaches £17,570, the starting-rate band is normally reduced to zero. The separate Personal Savings Allowance may still be available.
Starting-Rate Example
Suppose a person receives:
- £14,000 of employment income
- £2,000 of savings interest
The first £12,570 of employment income is covered by the Personal Allowance.
The remaining £1,430 of employment income reduces the £5,000 starting-rate band to £3,570.
Because the £2,000 of interest is below the remaining £3,570 starting-rate band, no Income Tax would normally be due on the interest. The Personal Savings Allowance would not need to be used in this example.

Can Someone Receive £18,570 of Interest Tax-Free?
In limited circumstances, yes.
A person with no wages, pension, trading profit, rental income or other taxable income could potentially receive:
- £12,570 covered by the Personal Allowance
- £5,000 covered by the starting rate for savings
- £1,000 covered by the basic-rate Personal Savings Allowance
That produces a potential total of £18,570 of tax-free savings interest in 2026–27.
This does not mean everyone can receive £18,570 tax-free. Other taxable income uses the Personal Allowance and reduces or removes the starting-rate band. The amount of interest can also affect the taxpayer’s tax band and entitlement to other allowances.
How Is Savings Interest Taxed in the UK?
Interest is added to the person’s other taxable income for the relevant tax year.
The normal order is broadly:
- Any available Personal Allowance is applied.
- The starting rate for savings is considered.
- The Personal Savings Allowance is applied.
- Remaining taxable interest is charged at the applicable savings Income Tax rate.
For the 2026–27 tax year, the principal UK savings rates remain:
| Savings tax band | 2026–27 rate |
| Basic rate | 20% |
| Higher rate | 40% |
| Additional rate | 45% |
The government has announced that the savings rates are scheduled to increase to 22%, 42% and 47% respectively from 6 April 2027. The starting rate for savings and the PSA are expected to remain unchanged, but the rules should be checked again for the relevant tax year.
Basic-Rate Taxpayer Example
A basic-rate taxpayer receives £1,350 of taxable-account interest.
- Personal Savings Allowance: £1,000
- Interest remaining: £350
- Tax at 20%: £70
The person would therefore pay approximately £70 of Income Tax on the interest, assuming no other allowance applies.
Higher-Rate Taxpayer Example
A higher-rate taxpayer receives £1,125 of interest.
- Personal Savings Allowance: £500
- Interest remaining: £625
- Tax at 40%: £250
The estimated Income Tax would be £250, subject to the person’s wider circumstances.
Which Types of Savings Interest Count?
Taxable savings income can include interest or returns from:
- Bank savings accounts
- Building society accounts
- Interest-paying current accounts
- Credit union accounts
- Fixed-term savings bonds
- Government and corporate bonds
- Peer-to-peer lending
- Certain National Savings and Investments products
- Accounts held outside the UK
HMRC confirms that bank interest, bond interest and several other savings returns can count towards the available savings allowances.
Interest should generally be considered in the tax year in which it becomes available to the account holder. This can be particularly important for multi-year fixed-rate bonds that credit all interest at maturity rather than annually.
Does ISA Interest Count Towards the Personal Savings Allowance?
No. Interest, income and gains generated inside an ISA are already tax-free and do not use the Personal Savings Allowance.
The total ISA subscription allowance for 2026–27 is £20,000. This is the maximum that an eligible adult can normally place into their ISAs during the tax year, rather than a maximum total ISA balance. Existing money can remain within the ISA wrapper and continue to benefit from tax-free treatment.
A saver could therefore have more than £20,000 in ISAs where money has accumulated over several tax years.
ISA holders do not normally need to declare ISA interest, income or capital gains on a Self Assessment return.
Are Premium Bond Prizes Tax-Free?
Premium Bonds do not pay conventional interest. Each eligible £1 bond is entered into a monthly prize draw.
NS&I confirms that Premium Bond prizes are free from UK Income Tax and Capital Gains Tax. An individual can currently hold up to £50,000 in Premium Bonds. However, returns are not guaranteed because an individual may win less than the published prize-fund rate or receive no prizes at all.
Premium Bonds should therefore not be treated as equivalent to a guaranteed interest-paying savings account.
Does HMRC Know How Much Savings Interest Someone Earns?
UK banks and building societies normally tell HMRC how much interest an account holder received after the end of the tax year.
HMRC uses this information alongside its records of employment, pension and other income to determine whether tax is due. Where a person is employed or receives a pension, HMRC may collect the estimated liability by adjusting their PAYE tax code.
Account holders should still check their annual interest certificates and Personal Tax Account. They remain responsible for ensuring the information used by HMRC is complete and accurate.
HMRC advises a person who has exceeded their savings allowance to make contact if they have not received a letter by 31 March following the end of the relevant tax year.
When Must Savings Interest Be Reported Through Self Assessment?
Someone who already completes a Self Assessment tax return should include taxable savings interest on the return.
A person generally needs to register for Self Assessment where their total income from savings and investments is more than £10,000. Where the amount is lower, HMRC may be able to collect the tax through PAYE or arrange another payment method.
The £10,000 figure is a Self Assessment reporting threshold for savings and investment income. It is not:
- A tax-free interest allowance
- A maximum permitted bank deposit
- A universal anti-money laundering threshold
- An amount that can always be received tax-free
That distinction is important because the previous version of this information could be interpreted as suggesting that deposits above £10,000 are automatically reported or taxed.
Do Banks Notify HMRC About Large Deposits?
There is no general UK rule stating that every deposit above £10,000 is automatically taxed or reported to HMRC solely because of its value.
Banks and other regulated businesses are required to monitor activity and report transactions or behaviour they suspect may involve money laundering, terrorist financing or criminal property. Suspicious Activity Reports are based on knowledge, suspicion or reasonable grounds for suspicion rather than one universal customer-deposit threshold.
A bank may request evidence explaining a significant or unusual payment. Appropriate evidence could include:
- A property completion statement
- Probate or inheritance documents
- A gift letter
- A business invoice
- A share-sale contract
- A payslip or bonus statement
- Evidence of a transfer from another account owned by the customer
A legitimate large deposit is not automatically taxable. Its underlying source determines whether tax has already been paid or whether a separate tax obligation exists.
Is Inherited Money Taxed When It Enters a Bank Account?
A beneficiary does not usually pay tax simply because inherited money is received in their bank account.
Inheritance Tax, where applicable, is normally dealt with by the estate before assets are distributed. There are exceptions, including certain gifts made within seven years of death, trusts and situations where the estate has not paid the liability.
After the inheritance has been received, any interest generated by the money belongs to the recipient and is considered under the normal savings tax rules.
For example, receiving a £100,000 inheritance may not create an immediate Income Tax charge. If the £100,000 later earns £4,500 of interest, that interest must be considered against the recipient’s savings allowances.
Are Cash Gifts Taxed When Deposited?
A genuine cash gift is not normally treated as employment or trading income for the recipient.
However:
- The recipient may pay tax on future interest generated by the gift.
- The donor’s estate may face Inheritance Tax consequences if the donor dies within seven years.
- Different rules can apply to trusts, gifts with conditions and international arrangements.
- Records should be retained to show that the payment was a genuine gift.
Transfers between spouses and civil partners are generally exempt from Inheritance Tax, although specialist rules can apply in unusual or cross-border cases.
Can Savings Be Transferred to a Spouse to Reduce Tax?
An outright transfer to a spouse or civil partner may allow future interest to be assessed using that person’s allowances and tax band.
The transfer must be genuine. Once the money is given away, the receiving spouse or civil partner must become its beneficial owner rather than merely holding the account as a nominee for the original owner.
This can be useful where one spouse is an additional-rate taxpayer and the other has unused allowances, but large transfers, estate-planning arrangements and international situations may require regulated financial or tax advice.
How Is Interest From a Joint Account Taxed?
HMRC normally treats interest from a joint account as being divided equally between the account holders.
For example, if a two-person joint account pays £1,200 of interest, HMRC will generally allocate £600 to each person. Each account holder then applies their own allowances and tax rate to their share.
Actual beneficial ownership can sometimes produce a different tax treatment, but simply adding another person’s name to an account does not necessarily transfer beneficial ownership of the money.
Can a Large Bank Balance Affect Benefits?
Although the balance itself is not normally subject to Income Tax, it can affect means-tested benefits.
Universal Credit
For Universal Credit:
- Capital of £6,000 or less normally does not reduce the award.
- Capital between £6,000 and £16,000 normally reduces the award.
- Capital above £16,000 usually prevents entitlement.
Between £6,000 and £16,000, Universal Credit is reduced by £4.35 a month for every £250, or part of £250, above £6,000.
Capital can include money held in current accounts, savings accounts, ISAs, Premium Bonds, cash and certain investments. Deliberately giving away or moving money to obtain more benefit can be treated as deprivation of capital.

Pension Credit
Pension Credit has different rules. There is no straightforward £16,000 upper limit, but savings above £10,000 are normally treated as producing £1 of weekly income for every £500, or part of £500, above the threshold.
Housing Benefit, Council Tax Reduction and social-care charging may apply different capital rules. Claimants should check the rules for the particular benefit or local authority scheme rather than assuming that the tax rules apply.
Can Savings Interest Affect Child Benefit?
Savings interest forms part of adjusted net income and can therefore affect the High Income Child Benefit Charge.
For 2026–27, the charge starts where either partner has individual adjusted net income above £60,000. It gradually withdraws Child Benefit and reaches 100% when the higher earner’s adjusted net income reaches £80,000.
For example, someone with employment income just below £60,000 could enter the charge if taxable savings interest takes their adjusted net income above the threshold.
The rules consider the income of the higher-earning partner rather than combining both partners’ incomes.
How Much Money Is Protected if a Bank Fails?
Tax allowances and deposit protection are separate issues.
From 1 December 2025, the Financial Services Compensation Scheme protects eligible deposits up to £120,000 per person, per authorised firm. The limit is not necessarily applied separately to every banking brand because multiple brands may operate under the same banking authorisation.
Qualifying temporary high balances may be protected up to £1.4 million for six months following certain life events, such as:
- Selling a main home
- Receiving an inheritance
- Receiving certain insurance payments
- Receiving a large pension payment
- Divorce or dissolution settlements
The protection applies only where the deposit and event satisfy the FSCS conditions. Someone holding more than £120,000 in cash savings may consider spreading eligible deposits across separately authorised firms after checking which brands share a banking licence.

How Much Cash Can Be Kept at Home?
There is no general Income Tax charge simply for keeping cash at home.
However, cash stored outside a bank account presents practical and legal considerations:
- It may not be covered fully by home insurance.
- It can be stolen, lost or damaged.
- It does not generate interest.
- Inflation may reduce its purchasing power.
- It still counts as capital for many means-tested benefits.
- Evidence of its legitimate source may be needed when it is eventually deposited.
Cash held at home is not outside the tax system. Undeclared business takings, rental income or other taxable income remain taxable regardless of whether they are kept in cash or placed in a bank.
How Can Savings Interest Be Reduced Legally?
Tax-efficient saving means arranging finances within the law rather than concealing income.
Common options include:
Use the ISA Allowance
Up to £20,000 can be subscribed to ISAs during 2026–27. Interest and gains generated within the ISA do not use the Personal Savings Allowance.
Use Both Partners’ Allowances
Spouses and civil partners may make genuine outright transfers so that savings are held by the person with available allowances or a lower tax rate.
Review Accounts Before the Tax-Year End
A saver approaching the PSA limit may consider transferring eligible money into an ISA before 5 April, subject to ISA rules and provider deadlines.
Consider Premium Bonds
Premium Bond prizes are tax-free, although they are not guaranteed and may not match the return from an interest-paying account.
Keep Records of Interest
Banks may issue annual interest certificates. Savers should retain these records and include interest from every taxable account when calculating the annual total.
Consider Pension Contributions
Certain pension contributions can reduce adjusted net income, potentially affecting tax bands and income-related charges. Pension decisions should be based on wider retirement objectives, fees, access restrictions and individual circumstances rather than tax alone.
What Happens if Taxable Interest Is Not Declared?
A taxpayer remains responsible for paying the correct amount even where a bank has reported interest directly to HMRC.
Failing to disclose taxable interest can lead to:
- Payment of the unpaid tax
- Late-payment interest
- Penalties
- A correction to the person’s tax code
- Investigation in more serious cases
HMRC may treat someone more favourably where they make an unprompted disclosure and correct an honest mistake promptly. Deliberately concealing UK or foreign interest can result in substantially more serious consequences.
Anyone who discovers undeclared interest should contact HMRC or correct the relevant Self Assessment return rather than waiting for HMRC to identify the discrepancy.
Can Overpaid Tax on Savings Be Reclaimed?
Someone who has paid too much Income Tax on savings may be able to request a refund.
People who do not complete Self Assessment can normally use form R40. HMRC allows claims for the current tax year and the previous four tax years, subject to the applicable conditions and deadlines.
A person who already files Self Assessment should normally make the claim through the tax return.
How Do Foreign Bank Accounts Affect UK Tax?
UK residents may need to pay UK tax on interest from overseas bank accounts, even where the money is not transferred to a UK account.
Foreign interest may need to be included in the foreign-income section of a Self Assessment return. Credit may sometimes be available where tax has already been paid overseas. Residence status, double-taxation agreements and the foreign income and gains regime can materially change the result.
International savers should not assume that an account is outside HMRC’s scope simply because the bank is based abroad.
Conclusion
There is no fixed amount of money that can be held in a UK bank account without tax. The bank balance itself is generally not subject to Income Tax. Instead, tax is normally based on the interest generated and the account holder’s wider taxable income.
For 2026–27, the main savings protections are the £12,570 Personal Allowance, the starting rate for savings of up to £5,000 and a Personal Savings Allowance of £1,000 for basic-rate taxpayers or £500 for higher-rate taxpayers.
Large balances may also affect means-tested benefits and should be considered against the £120,000 FSCS protection limit. Savers should keep annual interest records, use tax-free accounts where appropriate and check HMRC guidance whenever their income, interest or circumstances change.
Frequently Asked Questions
Is £10,000 in a Bank Account Tax-free?
The £10,000 balance itself is not taxed. Tax depends on the interest it earns and the account holder’s available allowances.
The separate £10,000 Self Assessment figure relates to income from savings and investments, not the amount deposited.
Is £50,000 in Savings Taxable?
The £50,000 balance is not automatically taxable. At an annual rate of 4%, it would generate approximately £2,000 of interest.
A basic-rate taxpayer with a £1,000 PSA might therefore have £1,000 of taxable interest, assuming no other allowance applies.
Is £100,000 in a Current Account Taxable?
Not merely because the account contains £100,000. Any interest paid on the balance may be taxable, and the original source of the money may have its own tax treatment.
The balance should also be considered against the £120,000 FSCS protection limit per eligible person, per authorised firm.
Does Hmrc Tax Every Bank Transfer?
No. Moving money between accounts does not normally create taxable income. HMRC considers the underlying transaction and source of the money.
Does Splitting Savings Across Several Accounts Increase the PSA?
No. The PSA applies to the total interest received by the individual across all taxable accounts, not separately to every bank.
Splitting money across separately authorised banks may improve FSCS protection, but it does not multiply the tax allowance.
Does Interest From an ISA Need to Be Declared?
No. Interest, income and gains generated within an ISA do not normally need to be declared on a tax return.
Are Joint Accounts Given a Separate PSA?
No. A joint account does not have its own PSA. Interest is normally divided between the account holders, who each apply their personal allowance to their allocated share.
Can a Person Receive Both the Starting Rate and the PSA?
Yes. A person with sufficiently low non-savings income may use the Personal Allowance, the starting rate for savings and the PSA in the same tax year.
Is Interest on a Foreign Savings Account Taxable?
It may be. UK residents generally need to consider overseas interest under UK tax rules, although residence-based exemptions, foreign tax credits and specialist regimes can apply.
Is Interest Earned by a Child Always Tax-free?
Not always. Where money given by a parent generates more than £100 of annual interest for a child, special parental settlement rules can apply. Junior ISA interest is tax-free and outside this rule.
Can HMRC Check Old Bank Interest?
Banks and building societies provide interest information to HMRC, and HMRC can investigate previous tax years where it believes income has been omitted. The period it can review depends on whether the error was reasonable, careless or deliberate.
