Introduction
UK withholding tax (WHT) creates compliance friction on both sides of cross-border interest and royalty payments. The payer must deduct tax at source — typically 20% — before transferring funds, while the recipient must decide whether to treat that withheld amount as a recoverable asset or an irrecoverable expense.
Many businesses struggle with recording gross income correctly, filing quarterly CT61 returns on time, and confirming whether a double taxation treaty reduces the 20% rate. Those mistakes trigger HMRC penalties, overstated expenses, and misstated balance sheets.
This guide covers each of those challenges directly: when UK WHT applies, how to record it from both sides of the transaction, how to present it on the balance sheet, and the most common accounting errors to avoid.
TL;DR
- UK WHT of 20% applies to "yearly" interest and royalty payments with a UK source — ordinary company dividends are exempt
- Payers deduct WHT and remit it to HMRC via quarterly CT61 returns filed within 14 days of quarter-end
- Recipients record gross income and classify WHT as a current asset (reclaimable) or expense (not reclaimable)
- Treaty relief can reduce or eliminate the 20% rate, but requires HMRC pre-authorisation or an active reclaim
What Is UK Withholding Tax and When Does It Apply?
Under the Income Tax Act 2007, Section 874, UK withholding tax (WHT) requires the payer — not the recipient — to deduct tax at source before making certain cross-border payments. This obligation applies whether or not the payer is based in the UK.
The standard rate is 20%, known as the savings basic rate. The UK government has proposed an increase to 22% from 6 April 2027.
Three payment types trigger UK WHT:
- "Yearly" interest with a UK source — short-term interest expected to run one year or less is generally exempt
- Patent, copyright, design, trademark, and know-how royalties — governed by ITA 2007 s.903 and Part 15 Chapters 6-7
- Property Income Distributions (PIDs) from UK Real Estate Investment Trusts (REITs) and Property Authorised Investment Funds (PAIFs)
Dividends paid by ordinary UK companies are exempt from WHT under domestic law.
Not every payment falls within scope, though. Several domestic exemptions eliminate the WHT obligation entirely.
Key Domestic Exemptions
No WHT needs to be deducted in these circumstances:
- UK-to-UK corporate payments — recipient is UK-resident and chargeable to UK corporation tax
- Quoted Eurobonds — interest on publicly listed bonds
- UK banks — payments to or from UK banks or UK permanent establishments of foreign banks
- Short interest — loans not intended to run beyond one year
- Qualifying private placement debt — interest on qualifying private placements by UK companies (not available for connected-party loans)

How to Account for Withholding Tax in the UK — Step by Step
Step 1: Identify the WHT Obligation and Set Up the Right Ledger Accounts
Payer's first action:
Determine whether the payment is subject to WHT under UK domestic law or reduced under an applicable double taxation treaty (DTT). Set up a "WHT Payable" liability account to hold the tax collected before remitting it to HMRC via CT61.
Recipient's first action:
Decide whether the withheld tax is reclaimable. Set up either:
- "WHT Recoverable" — a current asset account if you can offset the tax against your UK corporation tax liability or reclaim it under a DTT
- "WHT Expense" — a cost account if you cannot recover the tax
This decision must be made before posting entries, as it determines profit and loss and balance sheet impact. VJM Global's cross-border tax team helps foreign companies assess treaty entitlements and manage HMRC clearance filings to get this classification right from the outset.
Step 2: Record the Gross Transaction and WHT Journal Entries
For the Payer:
Debit the interest or royalty expense account with the gross amount, credit cash/bank with the net amount paid, and credit the WHT Payable liability with the tax withheld.
Example:
- Gross interest payment: £10,000
- WHT at 20%: £2,000
- Net payment: £8,000
Journal entries:
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Interest Expense | 10,000 | |
| Bank/Cash | 8,000 | |
| WHT Payable (Liability) | 2,000 |
For the Recipient:
Record the invoice/receivable at the gross amount (never at the net received). When the cash arrives, match the net amount received against the invoice and code the WHT shortfall to either the WHT Recoverable asset or WHT Expense account.
Example:
- Gross interest receivable: £10,000
- Net cash received: £8,000
- WHT withheld: £2,000
On raising the invoice (accrual basis):
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Interest Receivable (Asset) | 10,000 | |
| Interest Income | 10,000 |
On receiving payment:
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Bank/Cash | 8,000 | |
| WHT Recoverable (Asset) or WHT Expense | 2,000 | |
| Interest Receivable (Asset) | 10,000 |
Invoices must always be raised at full gross value.
Step 3: Report and Remit WHT to HMRC (Payer's Obligations)
Payers account for WHT using HMRC Form CT61, filed quarterly.
Filing deadlines:
- Return periods: Jan–Mar, Apr–Jun, Jul–Sep, Oct–Dec
- Submit and pay within 14 days after the end of each quarter
Before making a gross payment or applying a reduced treaty rate, payers must either:
- Confirm a domestic exemption applies
- Obtain prior authorisation from HMRC — particularly for interest payments
Critical risk: Failing to deduct WHT when required exposes the payer to the full liability plus interest and penalties — even if the recipient was entitled to treaty relief.
HMRC has paused its historical concession that previously allowed voluntarily disclosed late deductions to attract only late-payment interest. The current position is unambiguous: pay gross without an HMRC Direction and you owe the full 20%, regardless of treaty entitlement.
Step 4: Account for Withheld Tax as a Recipient
Once the payer has fulfilled its reporting obligations, the focus shifts to the recipient's books. The recipient receives net cash but must recognise gross income in the accounts. The withheld amount sits on the balance sheet as a recoverable asset until a double tax relief claim is processed through Self Assessment or the Corporation Tax return.
According to HMRC Company Taxation Manual CTM35220, income tax deducted at source is "set off against the CT liability" for the accounting period. If the income tax exceeds the CT liability, "the balance is repayable."
How the balance is ultimately cleared depends on whether relief is available:
- Relief not available: Transfer the balance to the profit and loss account as an irrecoverable expense
- Repayment received: Credit the WHT Recoverable asset account to clear it to zero
Is Withholding Tax an Expense or a Liability?
The answer depends on perspective:
For the Payer: WHT is a Liability
The payer acts as a collection agent for HMRC — responsible for collecting the tax and paying it to HMRC. WHT withheld and remitted is not the payer's expense. The payer's expense is the gross interest or royalty amount (the full contractual payment).
WHT payable appears as a current liability on the balance sheet — classified under taxes and social security creditors or other creditors — until remitted to HMRC via CT61.
For the Recipient: WHT is Either an Asset or an Expense
The correct treatment depends on whether double tax relief is available:
- DTT relief available: Hold the WHT as a current asset ("tax recoverable") on the balance sheet and offset it against the company's tax liability for the year.
- No DTT relief or relief denied: Treat the WHT as an expense in the income statement once it becomes clear recovery is not possible.
WHT recoverable is disclosed under current assets (or debtors) in the financial statements, separately identifiable from trade debtors. This classification aligns with FRS 102 Section 29 and IAS 12 principles for recognising current tax assets.
Common confusion:
The payer's gross payment remains their expense for both tax and accounting purposes. Misunderstanding this distinction leads to double-counting errors — where the payer incorrectly records both the gross payment and the WHT remittance as separate expenses.
Reducing or Reclaiming UK Withholding Tax
The UK has a double taxation treaty network covering over 130 countries. Many treaties reduce the 20% rate significantly — often to 0–10% for interest and 0–15% for royalties.
Representative Treaty Rates
| Treaty Partner | Interest WHT Rate | Royalties WHT Rate |
|---|---|---|
| UK-US | 0% or 15% | 0% |
| UK-Germany | 0% | 0% |
| UK-India | 10% or 15% | 10% or 15% |
Source: PWC UK Withholding Taxes
The UK-India treaty in particular involves tiered rates depending on the nature of the payment and the recipient's status — making it one of the more nuanced treaties to apply in practice. Once you know your applicable treaty rate, the next step is claiming that relief through the correct HMRC process.
Two Routes for Claiming Treaty Relief
1. HMRC Double Taxation Treaty Passport Scheme (DTTP)
This allows pre-approved lenders to receive interest gross without needing per-payment authorisation.
- Lender applies for a passport (valid 5 years) using Form DTTP1
- Borrower notifies HMRC within 30 days using Form DTTP2
- HMRC issues a Direction to Pay at the treaty rate
Guidance: DTTP Scheme Terms and Conditions
2. Filing a DTT Relief Application
Use Form DT-Individual or Form DT-Company before payment.
For royalties specifically, a payer can apply a reduced rate without prior HMRC clearance if they "reasonably believe" relief is due — but carry the risk if that belief proves incorrect. For interest, a formal HMRC Direction is required before paying at a reduced rate.

Domestic Exemptions That Eliminate WHT Entirely
UK domestic law provides several exemptions:
- Quoted Eurobond exemption — publicly listed bonds
- UK corporate exemption — recipient within UK corporation tax charge
- Private placement exemption — qualifying private placements (not available for connected parties)
Before making a gross payment under any exemption, confirm that all statutory conditions are met — incorrectly applying an exemption exposes the payer to the full 20% WHT liability, plus potential HMRC penalties.
Common Mistakes When Accounting for UK Withholding Tax
Payer Error: Making Gross Payments Without Clearance
The most common payer error is making gross payments without verifying whether a WHT obligation applies — or assuming a treaty exemption exists without checking the relevant treaty provisions or obtaining HMRC clearance.
The payer remains liable for the full WHT amount — plus penalties and interest — even if the recipient was treaty-exempt, unless pre-authorisation was secured. HMRC's paused concession means payers now face full 20% liability without mitigation.
Recipient Error: Recording Income at Net Amount
Recording income at the net (received) amount rather than the gross amount understates revenue and distorts the tax computation. Immediately expensing WHT that should be held as a recoverable asset also inflates costs and undervalues the balance sheet.
Correct approach: Always record gross income, then classify the WHT correctly based on recoverability.
Reporting Error: Missing CT61 Deadlines
Failing to file CT61 returns on time — or at all — for WHT deducted triggers automatic penalties. HMRC requires quarterly CT61 submissions even if the net amounts are small.
Penalty ranges under Schedule 24 Finance Act 2007:
- Careless: 0% to 30% of potential lost revenue
- Deliberate but not concealed: 20% to 70%
- Deliberate and concealed: 30% to 100%

Classification Error: Conflating WHT with PAYE or VAT
WHT is a distinct regime — don't confuse it with PAYE or VAT. Here's how the three differ:
| Regime | Applies To | Legislation | Filing |
|---|---|---|---|
| WHT | Payments to non-residents (interest, royalties, dividends) | ITA 2007 Part 15 | Quarterly CT61 |
| PAYE | Employment income | ITEPA 2003 | Real-time (RTI) |
| VAT | Consumption / supply of goods and services | VATA 1994 | Quarterly/monthly MTD |
Misclassifying WHT as a VAT or PAYE obligation leads to reconciliation errors and missed CT61 deadlines — both of which HMRC treats as separate compliance failures.
Conclusion
Accounting for UK withholding tax correctly means understanding both sides of the transaction. The payer must deduct, remit, and report via CT61; the recipient must recognise gross income and treat the withheld amount as either a recoverable asset or an irrecoverable expense, depending on treaty entitlement.
Errors in WHT accounting — under-deducting, misclassifying the withheld amount, or missing a treaty relief claim — can lead to unexpected tax liabilities, HMRC penalties, and misstated accounts. Businesses managing regular cross-border interest or royalty flows should work with a specialist who understands both UK mechanics and applicable treaty positions.

Frequently Asked Questions
How does UK withholding tax work?
UK WHT requires the payer to deduct income tax (typically 20%) at source from certain qualifying payments — primarily "yearly" interest and royalties with a UK source — and remit the deducted amount to HMRC, usually via a quarterly CT61 return.
How do you account for withholding tax?
For the payer, WHT is recorded as a liability (WHT Payable), not an expense. For the recipient, income is recorded at the gross amount — the withheld portion is held as a current asset if reclaimable, or expensed if irrecoverable.
Is withholding tax an expense or a liability?
It depends on the party: for the payer, WHT is a liability owed to HMRC (not their own expense); for the recipient, it is a current asset if covered by a double tax treaty (reclaimable) or an expense if irrecoverable.
What is the withholding tax rate in the UK?
The standard UK WHT rate is 20% on qualifying interest and royalty payments, with a proposed increase to 22% from 6 April 2027. Double taxation treaties can reduce this rate, often to 0–10% depending on the country.
Do I need to file a CT61 return for withholding tax?
Yes. Companies that have deducted WHT must submit a CT61 return to HMRC quarterly (within 14 days of each quarter-end) and remit the tax at the same time.
Can UK withholding tax be reclaimed under a double tax treaty?
Yes. Recipients resident in a treaty country may qualify for a reduced or zero WHT rate. Relief can be claimed upfront via prior HMRC authorisation or retrospectively through the relevant tax return or DTT Treaty Passport Scheme.
