Starting a new job comes with paperwork, payroll setup, and tax obligations, and one of the most important documents you may encounter is the HMRC Starter Checklist.
If you do not have a valid P45, this checklist helps your employer collect the correct information to place you on payroll and apply the right tax treatment from your first payday.
Completing the form accurately reduces delays, supports PAYE compliance, and lowers the risk of incorrect deductions.
Key highlights:
- HMRC Starter Checklist is used when you start a new job without a P45
- The checklist helps employers apply the correct tax code and process payroll
- Employee Statements A, B and C determine initial tax treatment
- The form is submitted to your employer, not directly to HMRC
- Accurate completion reduces payroll delays and incorrect tax deductions
What Is the HMRC Starter Checklist and Why Is It Important in 2026?
The HMRC Starter Checklist is a tax and payroll onboarding form used in the UK when a new employee starts work and does not have a current P45. It allows employers to collect essential details needed to process salary correctly under the Pay As You Earn (PAYE) system.
Previously known as the P46, the checklist was introduced to modernise onboarding and simplify how employers report starter information through payroll systems.
Rather than sending the physical form directly to HMRC, employers now use the information provided to submit employee details through Real Time Information (RTI) reporting.
In 2026, accurate completion remains especially important because payroll reporting operates in real time and tax coding decisions affect first pay immediately.
“Accurate employee onboarding information supports timely and correct PAYE reporting from the first payroll submission.” — HMRC payroll guidance principle
The checklist is designed to help employers:
- identify the correct employee record
- assign an initial tax code
- determine student or postgraduate loan deductions
- notify HMRC that employment has started
Without correct information, employers may need to apply temporary tax arrangements that could affect take-home pay.
Who Needs to Complete an HMRC Starter Checklist When Starting a New Job?
Not every employee needs a Starter Checklist. In many situations, a P45 from a previous employer already provides sufficient payroll information. However, there are several situations where the HMRC Starter Checklist becomes necessary.
Situations where the checklist is commonly required:
| Situation | Starter Checklist Needed |
| Starting first job | Yes |
| No P45 available | Yes |
| Returning after employment break | Usually |
| Multiple jobs | Yes |
| Self-employed moving into employment | Often |
| Valid and current P45 available | Usually No |
You may be asked to complete the checklist if:
- this is your first employment in the UK
- your previous employer has not issued your P45
- your details have changed since your previous employment
- you receive income from another employer or pension
- you have student or postgraduate loan repayments
- you are temporarily working in the UK for an overseas employer
The form helps ensure payroll reflects your actual employment situation rather than relying on assumptions.
Many employees assume this document is optional, but failing to provide accurate starter information often creates unnecessary tax adjustments later.
What Information Do You Need Before Filling Out the HMRC Starter Checklist?
Completing the HMRC Starter Checklist is straightforward if you prepare your information in advance. The online version cannot always be saved midway, so gathering documents beforehand reduces delays and errors.
Before you begin, you should have access to:
- full legal name
- current address and postcode
- date of birth
- National Insurance number (if known)
- employment start date
- student or postgraduate loan details
- information about previous earnings during the current tax year
- pension or benefit details where applicable
- passport number if temporarily assigned to work in the UK
If information is incomplete, employers may need to estimate payroll settings until HMRC provides updated instructions.
“Early collection of accurate employee data improves first-pay accuracy and reduces payroll corrections.” — UK payroll compliance guidance
How Do You Complete the HMRC Starter Checklist Correctly?
Completing the HMRC Starter Checklist correctly helps ensure accurate payroll and tax records from your first payday.
Whether you are starting a new job, changing employers, or joining without a P45, providing accurate information helps employers apply the correct tax treatment and avoid payroll errors. Preparing your details in advance can also make the process quicker and easier.
Accessing the Digital and PDF Starter Checklist
Employees can complete the HMRC Starter Checklist digitally through GOV.UK or use the downloadable PDF version where appropriate. HMRC also provides alternative forms for employees temporarily seconded into the UK.
The online process generally asks for employment status, previous income details, student loan information, and starter declaration selections.
Submitting the Completed Checklist to Your Employer
After completion, the checklist should be provided directly to your employer rather than HMRC.
Submission methods typically include:
- secure email
- printed copy
- HR onboarding platform
- in-person delivery
Employers then use the information to update payroll systems and submit starter details through RTI. A common misunderstanding is that employees must send the form themselves to HMRC.
In practice, payroll teams handle reporting after receiving the completed checklist. You should aim to complete the process before your first payroll cut-off date to avoid delays.
Which Employee Statement (A, B or C) Should You Choose on the HMRC Starter Checklist?
Choosing the correct employee statement on the HMRC Starter Checklist is important because it helps employers apply the right temporary tax code. Selecting the wrong option may lead to incorrect tax deductions until HMRC updates your payroll records.
Statement A – First Employment in the Tax Year
Choose Statement A if this is your first job since 6 April and you are not receiving taxable benefits or pension income. This usually applies to employees starting their first employment in the current tax year.
You may select Statement A if:
- this is your first job since 6 April
- you are not receiving taxable benefits
- you do not receive a state or workplace pension
Statement B – Previous Employment or Benefits
Select Statement B if this is now your only job, but you previously worked elsewhere or received taxable benefits during the current tax year.
Statement B may apply if:
- you left another job earlier this tax year
- this is now your only employment
- you received taxable Jobseeker’s Allowance or similar benefits
Statement C – Multiple Jobs or Pension Income
Choose Statement C if you currently have another job or receive pension income alongside your employment. Multiple income sources can affect your tax-free allowance.
Statement C usually applies if:
- you work for more than one employer
- you receive state, workplace, or private pension income
- you have another taxable income source
Employee Statement Comparison:
| Statement | When to Choose It |
| Statement A | First job since 6 April with no taxable benefits or pension |
| Statement B | Only current job but previous work or benefits this tax year |
| Statement C | Another job or pension income exists |
Selecting the correct statement helps reduce payroll errors and avoids unnecessary tax adjustments later.
How Does the HMRC Starter Checklist Affect Your Tax Code and First Payslip?
Your completed checklist becomes one of the first data sources used to determine how payroll calculates deductions.
Employers enter starter details into payroll software and submit a Full Payment Submission (FPS) through RTI. HMRC then reviews available records and confirms whether adjustments are required.
Tax outcomes influenced by the checklist include:
- PAYE income tax calculations
- National Insurance deductions
- student loan repayments
- postgraduate loan deductions
- emergency tax application where necessary
A completed checklist does not automatically guarantee your final tax code is correct immediately. In some cases, payroll may initially use temporary coding until HMRC updates records.
“Real Time Information allows payroll systems to align employee tax positions more efficiently across employment changes.” — UK employment tax reporting principle
Your first payslip should always be reviewed carefully. If deductions appear unusual, check your HMRC tax account and speak with payroll promptly.
What Should Employers Do After Receiving a Completed HMRC Starter Checklist?
Once an employer receives the completed checklist, their responsibility moves beyond document collection. The information must be reviewed, entered into payroll software, and used for employee onboarding and reporting.
Employer responsibilities:
- validate employee details
- assign payroll records
- determine National Insurance category
- process PAYE correctly
- submit employee data through FPS
- store checklist records securely
Employers do not send the physical checklist to HMRC.
Record retention expectations:
| Record Type | Recommended Retention |
| Starter Checklist | Current year plus previous 3 tax years |
| Payroll records | According to payroll compliance rules |
| RTI submissions | Maintain reporting history |
Maintaining accurate records protects businesses during audits and supports future employee queries. Good onboarding processes also create a better employee experience and reduce payroll administration later.
What Are the Most Common HMRC Starter Checklist Mistakes to Avoid?
Most HMRC Starter Checklist mistakes happen because details are entered too quickly or without proper checks. Even small errors can lead to incorrect tax codes, payroll delays, or inaccurate deductions.
Common HMRC Starter Checklist Mistakes:
| Mistake | Impact | Solution |
| Wrong employee statement | Incorrect tax code | Review Statements A, B, and C carefully |
| Incorrect NI number | Payroll delays | Double-check NI details |
| Wrong student loan plan | Incorrect deductions | Confirm repayment plan before submission |
| Using an outdated form | HMRC reporting issues | Use the latest HMRC version |
| Submitting both P45 and checklist | Duplicate payroll records | Only use one valid document |
| Late form submission | Payroll errors | Submit before payroll deadlines |
Checking all details before submission can help employers and employees avoid unnecessary payroll and tax complications later.
Conclusion
The HMRC Starter Checklist plays an important role in helping new employees start work smoothly and ensuring employers process payroll correctly from the outset.
Whether you are beginning your first job, changing employers, or starting without a P45, completing the checklist accurately can help prevent tax issues and payment delays.
By understanding the requirements, selecting the correct employee statement, and submitting information on time, you can make your transition into a new role much easier.
