A Guide to Understand the UK’s NT Tax Code

Home / NT Tax Code

Taxes in the UK sometimes feel confusing. There are different tax codes, rules, and deductions; this makes it difficult to know how much income tax one needs to pay tax on. One such code that often raises questions is the NT tax code.

People mainly use the NT tax code in situations where the PAYE system does not deduct their UK income tax. It commonly applies to people who are non-UK residents and who receive UK pension income or are covered by a double taxation agreement with another country.

For such non-UK residents seeking tax guidance, this guide explains what the NT code means for them, when it applies, and how it affects your tax status.

What is the NT Tax Code?

The NT tax code stands for No Tax. This means that when this tax code NT is applied, then the employer, pension provider, or payroll system does not deduct income tax from the payment.

In other words, the payer will not deduct tax at source because the income is not taxable in the UK for tax purposes.

Normally, the PAYE system automatically deducts income tax before salary or pension income is paid. However, when HMRC assigns the NT code, it instructs the payer not to make any tax deduction.

This applies to wages, pension withdrawals, or income withdrawal from certain UK pension schemes.

When Does the NT Tax Code Apply?

HM Revenue usually issues the NT tax when a person is a non-resident for UK tax purposes. It often applies in situations that involve overseas residency and double taxation arrangements.

Some common scenarios include:

1. Non-UK Residents

If you are a non-UK resident and no longer come under the bar of a UK tax resident, then you may not need to pay tax on certain UK income. However, if your country of residence has an agreement with the UK, then it can tax your income in that country.

Under these double tax agreements, HMRC may issue the NT tax code so the employer or pension provider does not deduct income tax.

2. Pension Income for Overseas Residents

There are many individuals who are living abroad and receive UK pension income from a UK pension scheme.

If the relevant double taxation agreement states that pension income should only be taxed in the individual’s country of residence, HMRC may apply the NT code.

This makes sure that the pension trustee or pension provider does not make unnecessary tax deductions when they are processing pension withdrawals, or they are deciding if to make withdrawals from the pension.

3. Special HMRC Instructions

In some cases, HMRC may assign a special tax code like tax code NT after they review the taxpayer’s tax status or tax resident position.

For example, if the income should be taxed elsewhere under double tax agreements, then the tax office may apply the code to stop automatic UK tax deductions.

How the NT Tax Code Works in Practice

When the NT tax code is issued, the payroll system processes income without deducting UK income tax.

For instance, suppose a person lives permanently in another country and he is considered a non-resident for the UK tax year. They receive pension income from a UK pension scheme.

If their country of residence has a double taxation agreement with the UK, then the pension provider may apply the NT code.

This means that the pension payment is paid without any tax deduction in the UK, and the taxable income will instead be calculated and taxed by the local tax authority in the individual’s country.

Difference Between NT Code and Emergency Tax Code

Many people confuse the NT tax code with an emergency tax code or the BR tax code, but they serve very different purposes.

People use the emergency tax code when HMRC does not yet have complete information about your earnings or tax status. This temporary code makes sure that the tax is deducted until the correct tax code is issued.

The NT code, however, does the opposite. It tells the payer not to deduct tax at all.

If the wrong code is applied, it may lead to overpaid tax or unnecessary tax deductions, which can later be corrected.

Personal Allowance and NT Tax Code

Under normal circumstances, individuals benefit from the personal allowance, also called the UK personal allowance, which is the tax-free amount of income that you earn before you pay tax, and higher earners may move into the 40% income tax bracket.

However, if you are a non-resident, then you may not always be eligible for the tax free allowance depending on your tax purposes and residency rules.

Instead of applying the basic rate or adjusting the personal allowance, HMRC may issue the NT tax code if your income is exempt from being taxed under the UK system, but it is still important to understand how UK tax codes work overall.

How to Apply for an NT Tax Code

If you believe the NT tax code should apply to your situation, you may need to apply for an NT through HMRC and make sure you are aware of when the UK tax year starts and ends.

Typically, you must:

  • Confirm your residence and non-resident tax status.
  • Provide details of your country of residence.
  • Show that a double taxation agreement applies.

You may also need to complete certain forms confirming that your income will be taxed in another country, or be assessed through HMRC’s Simple Assessment Tax Scheme if your circumstances meet the criteria.

Sometimes the pension provider, pension trustee, or employer will request confirmation from HMRC before they apply for the NT code to their payroll system, especially where smaller trading or side-income needs to be checked against the trading allowance for taxpayers.

What to Do If Too Much Tax Has Been Deducted

In case your tax code was incorrect in the previous years, then you may have had tax deducted unnecessarily.

In such cases, you may need to claim a refund for overpaid tax, and many people choose to work with a tax adviser or accountant for their tax return to make sure the claim is correct.

This can be done by:

  • Filing a self assessment return
  • By asking HMRC to review your tax paid
  • Contact the tax office

You can contact HMRC directly to confirm if your tax status has been correctly recorded, or take advice from a qualified Chartered Tax Adviser in the UK if your affairs are more complex.

Once they issue the correct tax code, future payments should be made without UK income tax deductions, although ongoing support from professional tax advisory services can help you stay compliant.

Conclusion

The NT tax code plays an important role in preventing double taxation for individuals who are non UK resident but still receive UK income, particularly pension income.

By instructing employers or pension providers not to deduct income tax, the NT code makes sure that the taxable income is only taxed in the correct country under applicable double tax agreements.

However, tax rules can vary depending on your tax resident status, the country of residence, and the type of income withdrawal or pension payment involved.

If you are unsure if you should apply for an NT, it is always best to contact HMRC directly or seek professional advice to make sure that your UK tax obligations are handled correctly.

Frequently Asked Questions

What does “NT” mean on a payslip?

“NT” on a payslip refers to the NT tax code. Under this tax, no income tax is deducted from your payment through the PAYE system. Precisely, this only happens when HMRC decides that they don’t have to deduct any income as a taxed income in the UK.

The “T” in a tax code means that your taxable income requires special calculations. HMRC may apply it when your personal allowance, UK tax deductions, or earnings need a revision.

1257L is the standard UK tax code that represents the UK personal allowance of £12,570. Other tax codes, such as the 1263L tax code and its allowance, work in a similar way by showing how much tax-free income you can receive. If an extra letter like “N” appears, it usually indicates a change in tax status or adjustments to how the allowance is calculated.

The NT code means no UK income tax should be deducted from your income. It is often used when someone is non UK resident or covered under a double taxation agreement, and it operates differently from common codes like the 1247L tax code and its allowance.

NT tax status means the taxpayer’s income is not subject to UK tax at source. Instead, the taxable income may be taxed in the individual’s country of residence under different circumstances, and this is distinct from standard personal-allowance codes such as the 1265L tax code and its impacts or complex adjustment codes like the T tax code and its different aspects.
