The 1263L tax code is an HMRC PAYE tax code for UK employees who receive an increased Personal Allowance of £12,630, exceeding the standard £12,570 threshold.
This enhanced allowance reflects additional entitlements, such as verified expense claims, updated employment benefits, or adjustments from HMRC reconciliations, that raise your tax-free income.
A 1263L code provides £60 more tax-free pay than the common 1257L code, making it a favourable code for taxpayers seeking maximum annual relief.
Employees with a 1263L tax code benefit from a higher-value Personal Allowance with no restrictions, placing it among the positive L-suffix codes HMRC issues after reviewing an individual’s circumstances.
The 1263L tax code serves as a precise indicator that HMRC has recognised legitimate allowances directly tied to your employment and financial profile.
What is the 1263L Tax Code in the UK?
To fully appreciate the benefits of the 1263l tax code, we must first understand the two core components that make up any UK tax code: the numbers and the letter.
What Does Tax Code 1263 Mean? The Numerical Component
The number 1263 is the crucial part of the code, and answering the query, “What does tax code 1263 mean?” is straightforward: it represents your total tax-free Personal Allowance for the current tax year, expressed in tens of pounds.
-
Calculation: You take the number (1263) and multiply it by 10.
-
Result: 1263 x 10 = £12,630.
This means that for the entire tax year (running from 6 April to 5 April), you are legally entitled to earn £12,630 before any Income Tax is deducted from your wages under the Pay As You Earn (PAYE) system.
For context, the standard Personal Allowance, which is the amount most people receive, has been frozen at £12,570 since the 2021-22 tax year (and up to 2027-28), which corresponds to the 1257L code.
What Code is 1263? Unpacking the Letter ‘L’
The letter suffix in the 1263l tax code confirms the status of the allowance, directly addressing the question, “What code is 1263?” (or rather, what the full code signifies).
The ‘L’ is the most common suffix and indicates two primary facts:
-
Standard Entitlement: You are entitled to the full standard Personal Allowance.
-
Tax Rate Status: You are not claiming Marriage Allowance (M or N), nor do you have complex tax affairs that require HMRC to review your code annually (T).
In short, the L confirms that your tax-free allowance is calculated against the basic, higher, and additional tax rates (depending on where you fall in the income brackets) and that you are not under an emergency code like W1 or M1.
Why is the 1263L Tax Code Considered a Hidden Gem?
The key to the 1263l tax code being dubbed a “hidden gem” lies in the £60 uplift (£12,630 vs the standard £12,570).
This seemingly small adjustment is almost universally triggered by claiming Flat Rate Expenses (FREs) for job-related costs.
The Mechanics of the £60 Uplift
HMRC allows employees to claim tax relief on certain employment expenses they incur but are not reimbursed for by their employer.
If these expenses are small and predictable, HMRC often grants a Flat Rate Expense allowance, simplifying the claim process.
The most common Flat Rate Expense is the Uniform Laundry Allowance. Many professions require staff to wear a uniform (e.g., nurses, teachers, police, industrial workers), and if the employer does not provide laundry facilities, the employee must wash the uniform at home.
Rather than requiring receipts for soap powder and utility bills, HMRC provides a fixed annual amount for different job roles.
For many employees, this standard FRE amount is £60.
Calculation of 1263L:
| Component | Value | Tax Code Impact |
| Standard Personal Allowance (PA) | £12,570 | 1257 |
| Plus: Flat Rate Expense (e.g., Laundry) | + £60 | + 6 |
| Total Personal Allowance | £12,630 | 1263L |
By adding this £60 to your Personal Allowance, HMRC increases the amount of income you receive tax-free, effectively reducing your taxable pay and granting tax relief on the expense.
At the basic rate of 20%, that £60 allowance translates to a tax saving of £12 per year. While this might sound minor, it confirms you are utilising your tax entitlements fully, and crucially, this uplift remains in your 1263l tax code until your circumstances change or HMRC reviews the flat rates.
Common Professions Eligible for the Flat Rate Uplift
While the £60 allowance is common, many professions have higher approved flat rates. For instance, some construction workers, police, or certain NHS staff may have higher FREs (e.g., £100, £140, or more) due to the nature of their work or the cost of maintaining specific tools/clothing.
Crucially, a tax code like 1263L confirms that a claim has been made, processed, and coded.
For a detailed, authoritative breakdown of what employment expenses you can claim, and the various flat rate amounts, always consult the official guidance provided by HM Revenue and Customs (HMRC) on job expenses and relief. (Source 3.4 & 3.5 indicate claiming expenses is done via P87).

Who Qualifies for the 1263L Tax Code?
HMRC doesn’t assign tax codes randomly. The 1263L tax code is usually given to individuals who have claimed tax relief on job-related expenses, such as:
- Uniform maintenance
- Tools or specialist equipment
- Professional subscriptions (e.g., membership to a trade body)
- Mileage for work-related travel (excluding your normal commute)
When you successfully claim these deductions, your Personal Allowance increases to reflect the amount you’re allowed to earn tax-free, which is how you may end up with the 1263L code instead of the standard 1257L.
Key Comparisons: 1263L vs. Other Common Tax Codes
Understanding the significance of the 1263l tax code requires comparing it directly to the codes most frequently encountered by UK taxpayers.
Is Tax Code 1263L Better than 1257L?
In simple financial terms, yes, the 1263L tax code is better than the 1257L tax code—if and only if you are eligible for the extra allowance.
| Feature | 1257L Tax Code | 1263L Tax Code | Outcome for Taxpayer |
| Personal Allowance (PA) | £12,570 | £12,630 | £60 higher PA |
| Meaning | Standard, full PA entitlement. | Standard PA + £60 in allowances/relief. | More tax-free income. |
| Taxable Income | Income over £12,570 is taxed. | Income over £12,630 is taxed. | Lower taxable income. |
| Mechanism | No job expenses claimed/coded. | An allowable expense claim (usually FREs) has been approved. | Financial advantage. |
The 1263l tax code provides an extra £60 of tax-free earnings compared to the 1257L code. For a basic rate taxpayer, this translates to an extra £12 in your take-home pay over the year, paid out incrementally in each pay cycle.
While the cash difference is minimal, it serves as proof that you have successfully reduced your tax liability by claiming an entitlement for necessary work costs.
If you have a 1257L code but believe you should be cleaning your own uniform or paying for essential professional subscriptions, it means you have not yet claimed the relief that could grant you the 1263l tax code.
Addressing Other Common Codes
When discussing the standard L code, other similar codes often come up, particularly in search queries. One that frequently appears is “Is 1256L a normal tax code?”
Is 1256L a normal tax code?
The short answer is: it is not the standard code, but it is a normal, calculated code.
If the standard Personal Allowance is £12,570 (1257L), then a 1256L tax code means your Personal Allowance is £12,560. This indicates that HMRC has reduced your allowance by £10.
-
1257L (Standard PA) = £12,570
-
1256L (Your PA) = £12,560
This slight reduction often happens due to a very small amount of untaxed income or an undeclared benefit-in-kind.
For example, a minor taxable benefit that adds £10 to your taxable income for the year might result in HMRC reducing your tax code by 1 (which represents £10 of allowance).
It’s essential to check your Personal Tax Account if you see a code like this, as it signals a deduction, unlike the beneficial uplift associated with the 1263l tax code.
Other common codes you might encounter include:
-
K Codes: These mean your deductions are greater than your Personal Allowance, resulting in a negative allowance.
-
0T: You have used up all your Personal Allowance, and all your income is now taxable.
-
BR: Basic Rate tax only, often used for a second job where your PA is used against your main employment.

How is the 1263L Tax Code Calculated?
According to HMRC, the tax code is calculated based on your total income, minus any tax-free allowances and eligible deductions. The standard Personal Allowance for the 2025/26 tax year is £12,570, but this can increase if:
- You successfully apply for tax relief on job expenses.
- You receive marriage allowance from a partner.
- You are not claiming any benefits in kind, like a company car or private medical insurance.
These extra reliefs are subtracted from your taxable income, hence adjusting your code from 1257L to 1263L.
The Mechanism of Coding Out Expenses
The reason why HMRC uses the tax code to administer the relief for job expenses is known as ‘coding out’ the expense.
This is generally preferred over issuing a cash refund because it is simpler and more efficient for both the taxpayer and the Exchequer.
Instead of waiting until the end of the tax year to reclaim the tax on your £60 allowance, HMRC proactively adjusts your allowance before tax is calculated.
-
Standard Method (1257L): Taxable Pay = Income – £12,570
-
1263L Method: Taxable Pay = Income – (£12,570 + £60 relief) = Income – £12,630
By reducing your taxable income on a monthly or weekly basis, the tax relief is smoothed out across the year, resulting in the correct tax being deducted from the outset.
This system requires you to only claim the expense once, and it will remain coded in your allowance (for example, generating the 1263l tax code) until HMRC is informed of a change in your circumstances.
Addressing the Confusion: What Code is 1263?
In the context of UK PAYE, a code number of 1263 must be followed by a letter to be valid. The number 1263 itself is simply a numerical value representing the tax-free personal allowance of £12,630.
Since this amount is greater than the standard Personal Allowance, the associated letter will almost always be ‘L’ (standard allowance) or sometimes ‘T’ (if the adjustment is part of a more complex calculation that needs review).
Therefore, when reviewing your documents or dealing with payroll, you are looking for the full, complete tax code: 1263L. This clarity is essential for avoiding payroll errors and for accurate record-keeping.
Benefits of Having the 1263L Tax Code
- Increased Take-home Pay: £60 extra per year may not break the bank, but every little helps, especially over multiple years.
- Possible Indicator of Missed Reliefs: If you don’t have the 1263L code and think you qualify, it might mean you’re missing out on reliefs you’re entitled to.
- Reduces Risk of Overpayment: With the correct tax code, your PAYE deductions will be more accurate.
Managing Your 1263L Tax Code
As experts in UK taxation, our primary role is to ensure clients understand their financial standing and take proactive steps to maintain accuracy.
The stability of your 1263l tax code depends on your circumstances remaining unchanged.
1. How the 1263L Tax Code is Issued
You do not automatically receive the 1263l tax code. It is almost always a result of a claim you or a previous accountant submitted to HMRC.
-
Initial Claim: If your total job expenses are under £2,500 for the tax year, the claim is typically made using a Form P87 (or via your Personal Tax Account).
-
HMRC Processing: Upon approval, HMRC updates your tax code and sends a Notice of Coding (P2) to you, and a new code notification (P9) to your employer, instructing them to use the 1263l tax code going forward.
-
Self Assessment: If your annual job expenses exceed £2,500, or if you already file a tax return for other income (e.g., property, self-employment), the claim must be made through your Self Assessment tax return.
2. When the 1263L Tax Code Might Change
The 1263l tax code is a representation of your specific circumstances. Any change to your income, benefits, or entitlements will prompt HMRC to issue a new tax code.
Reasons your code might move away from 1263L:
| Change in Circumstance | Potential New Code | Explanation |
| Ending the Expense | 1257L | You switch to a non-uniform job, or your employer starts reimbursing your laundry costs. The £60 relief is removed. |
| New Company Benefit | Lower than 1257L (e.g., 1200L) | You receive a taxable benefit-in-kind (like private medical insurance or a company car). The value of this benefit is deducted from your allowance. |
| New Second Job | BR (on the second job) | Your main job maintains the 1263l tax code and uses the allowance, leaving the second job taxed at the Basic Rate. |
| Income Exceeds £100,000 | Tapered/Lowered L Code | Your Personal Allowance is reduced by £1 for every £2 of income over £100,000, eventually leading to a 0T code above £125,140. |
3. Verification: Why You Must Check Your Coding Notice
Never ignore a Notice of Coding (P2) from HMRC. This document details exactly how your 1263l tax code (or any other code) was calculated, listing the additions and deductions applied to your standard Personal Allowance.
This is your opportunity to review and verify that the £60 allowance is still correctly included and that HMRC hasn’t mistakenly included a deduction that no longer applies (e.g., a company car you returned months ago).
You can check your current tax code, review the underlying calculation, and update your details quickly using your HMRC Personal Tax Account.

The Role of the Personal Allowance Freeze
Since the standard Personal Allowance (PA) has been frozen at £12,570, the relative benefit of the £60 uplift found in the 1263l tax code has become subtly more important.
As wages rise due to inflation and salary reviews, more of an individual’s income is pushed into the taxable bracket, making every single pound of tax-free allowance more valuable.
The Personal Allowance freeze means that the standard £12,570 allowance remains fixed, but your statutory entitlements, such as the £60 Flat Rate Expense, ensure that individuals with the 1263l tax code are shielded from tax on this specific expense amount.
It represents the government’s commitment to ensuring that necessary work costs do not become an uncompensated burden on the employee.
Why Claiming the Flat Rate Expense is Crucial
Some people may feel that the £12 annual saving derived from the £60 allowance (which leads to the 1263l tax code) is not worth the effort of submitting a P87 form.
However, a responsible accountant will always advise claiming what you are legally entitled to.
-
Compliance and Accuracy: Using the correct tax code (1263l tax code) ensures you are fully compliant with UK tax law and paying the exact amount of tax due.
-
Cumulative Value: The relief can be backdated up to four tax years. A simple claim can result in a one-off tax refund of potentially £48 (4 x £12) plus the ongoing benefit of the adjusted code.
-
Future-Proofing: Once the expense is ‘coded out’ via the 1263l tax code, it automatically carries forward into future tax years unless HMRC or you are informed otherwise. This means you do not need to re-claim every year.
The Nuance of 1256L vs 1263L
Let’s return to the comparison, as it highlights the binary nature of tax codes:
-
If you hold the 1263l tax code, you are receiving a net annual addition of £60 to your allowance.
-
If you hold a 1256L tax code, you are receiving a net annual deduction of £10 from your allowance.
An individual who has failed to claim their £60 laundry allowance might have a 1257L code, while a colleague who has claimed it correctly benefits from the 1263l tax code.
Both are technically “normal” in that they are calculated by HMRC, but the 1263l tax code is objectively more advantageous due to the inclusion of the entitlement.
What to Do If You’re Not on the 1263L Code But Think You Should Be
If you wear a uniform, use your own tools, or pay for work-related travel, you could be eligible for tax relief. To make a claim:
- Visit HMRC’s official expense claim page:
- Submit your claim online via your Personal Tax Account.
- Wait for HMRC to review and potentially adjust your tax code to something like 1263L.
What if My Tax Code Changes Mid-Year?
Tax codes are dynamic, they change if your income, benefits, or employment status changes. If you move jobs, get a pay rise, or stop claiming expenses, HMRC might update your code.
It’s essential to review any changes immediately and ensure they reflect your current situation.

Frequently Asked Questions about UK Tax Codes
Q: What does tax code 1263 mean?
The 1263l tax code signifies a Personal Allowance of £12,630 for the tax year. This is calculated as the standard Personal Allowance of £12,570 plus an additional allowance of £60, usually for approved job expenses such as the Flat Rate Expense for laundering a work uniform.
Q: What code is 1263?
The full code is typically 1263L. The numerical part (1263) denotes the tax-free amount (£12,630), and the letter ‘L’ confirms that the taxpayer is entitled to the standard Personal Allowance rate. Any code number, including 1263, must be followed by a letter (or letters) to be fully functional within the PAYE system.
Q: Is tax code 1263L better than 1257L?
Yes, the 1263l tax code is financially better than the 1257L tax code. The 1263l tax code provides an additional £60 in tax-free income over the year, resulting in a slightly higher take-home pay, because it incorporates a valid tax-deductible expense.
Q: Is 1256L a normal tax code?
A 1256L tax code is a calculated tax code, and therefore normal, but it is not the standard code. It means your tax-free allowance is £12,560, which is £10 less than the standard £12,570 Personal Allowance. This minor reduction is typically due to a small amount of untaxed income or a minor benefit-in-kind that HMRC is collecting tax on. It is important to check the calculation details behind a 1256L tax code to ensure it is accurate.
Q: How do I claim the allowance that leads to the 1263L tax code?
If your job expenses are below £2,500 annually and you do not file a Self Assessment, you can claim the Flat Rate Expense (FRE) using the HMRC online service or Form P87. Once approved, HMRC will issue the 1263l tax code to your employer.
Q: Does the 1263L tax code stay the same every year?
The underlying allowance remains coded out, but the number (1263) may change if the standard Personal Allowance or the Flat Rate Expense amount is adjusted by the Chancellor in a Budget announcement. However, the mechanism granting the uplift remains in place until you inform HMRC of a change in your employment circumstances.
The Bottom Line: Is the 1263L Tax Code Worth the Hype?
The 1263l tax code is more than just a sequence of digits; it is verifiable proof that you have successfully navigated the process of claiming tax relief for essential employment expenses.
This “hidden gem” represents accurate, compliant taxation and a subtle, but significant, boost to your annual take-home pay compared to the common 1257L tax code.
Whether you currently hold the 1263l tax code, or you are now motivated to check if you are eligible to move from a code like 1257L to the more advantageous 1263L tax code, the key message remains the same: diligence in understanding your tax affairs always pays dividends.
