Changing jobs is a normal part of a doctor’s career. Doctors may move between NHS trusts, change hospitals, progress into more senior positions or combine employment with additional professional work.
From a career perspective, such changes may simply represent the next stage of professional development. From an administrative perspective, however, moving between employers can create additional financial records that need to be kept organised.
For doctors completing Self Assessment, understanding what happened during the entire tax year is important. A return needs to reflect the relevant income and circumstances across the year, rather than focusing only on the doctor’s current employer.
One Tax Year Can Include Several NHS Employers
A doctor who changes NHS employment during the year may receive income from more than one organisation.
For example, a doctor could spend part of the tax year working for one NHS trust before accepting a position with another. There may be different payslips, employment records and tax information associated with each role.
This does not necessarily make the tax position complicated by itself. The difficulty often comes from keeping track of all the information.
Doctors should therefore retain documentation from previous employers even after moving to a new position. Records relating to the earlier employment remain relevant to the tax year in which that employment took place.
P45 and P60 Records Can Help Build the Picture
Employment documentation provides an important record of salary and tax deducted through PAYE.
A P45 may be issued when employment ends, while a P60 provides information about employment income and tax for the relevant tax year.
Doctors changing jobs should keep these documents safely rather than assuming that information from a previous employer is no longer needed.
Payslips can also provide useful supporting information, particularly where there have been changes in salary, additional payments or employment arrangements during the year.
Maintaining these documents in one place can make the eventual review considerably easier.
Changes in Tax Codes Should Be Reviewed
A change of employer can sometimes coincide with a change in tax code.
Doctors moving between employers should pay attention to the information appearing on their payslips and employment records. If something appears inconsistent, it can be useful to investigate it rather than allowing the issue to remain unnoticed.
This is particularly relevant when someone has multiple employments or changes jobs more than once during the same tax year.
Self Assessment does not replace the importance of checking PAYE records. Instead, the two systems can form part of the wider picture of a doctor’s tax position.
Additional Work May Continue During a Job Change
A change of NHS employer does not necessarily mean that other professional activities stop.
A doctor may continue undertaking locum shifts, private consultations, teaching, examining or other professional work while moving from one NHS position to another.
This can result in a tax year containing several distinct types of income.
The doctor’s records should therefore reflect the full range of professional activity rather than treating the new NHS salary as the only relevant figure.
A useful approach is to maintain separate records for each source of income throughout the year.
Moving Jobs Can Change Professional Expenses
Career changes can also affect expenses.
A new position may involve different professional requirements, equipment, training or travel arrangements. A doctor may also incur costs connected with professional memberships or other responsibilities during the transition.
However, an expense being associated with a job change does not automatically determine its tax treatment.
Doctors should retain receipts and other supporting documents and consider the circumstances of each expense before including it in their tax calculations.
Clear records make it easier to establish what a payment related to and which professional activity it concerned.
Avoid Reconstructing the Year From Memory
Doctors have demanding working schedules, and a job transition can involve contracts, onboarding, relocation, rota changes and new clinical responsibilities.
Financial administration can easily become secondary.
Months later, however, trying to remember which employer paid a particular amount or when a particular professional expense occurred can be difficult.
This is why keeping records at the time can be more effective than attempting to reconstruct everything before the Self Assessment deadline.
A simple folder for each tax year can contain employment documents, payment records and relevant expenses. Digital copies can also provide a practical backup.
What About a Doctor Who Has Three Employers?
Some doctors may work for more than two NHS organisations during a single tax year.
This could happen through short-term appointments, temporary positions or other employment arrangements.
The principle remains the same: the doctor should maintain records covering the entire period and each relevant source of employment income.
Where several employers are involved, it becomes particularly important to check that the documentation is complete.
A useful checklist might include:
- Employment dates for each NHS organisation
- P45s where employment ended
- P60 information
- Relevant payslips
- Details of any additional professional income
- Locum payment records
- Private practice records where applicable
- Professional expense documentation
- Records of significant changes during the tax year
Keep Previous Employer Records After Moving
One common administrative mistake is to discard old employment documents after starting a new role.
A new employer may become the focus of day-to-day administration, but the previous employer’s records can still be relevant to the tax year.
Doctors should therefore retain historical employment documentation according to appropriate record-keeping requirements.
Keeping everything organised by tax year rather than simply by current employer can be particularly useful.
For example, a folder labelled with the tax year can contain information from every NHS employer and additional professional activity undertaken during that period.
Specialist Advice Can Simplify Complex Changes
Most doctors changing jobs will not need to treat a career move as a tax crisis. The more useful approach is simply to recognise that a change in employment can alter the information that needs to be reviewed.
Where a doctor has several employers alongside locum, private or other professional income, specialist advice can help bring the different records together.
A self assessment accountant for doctors can work from the doctor’s complete financial information rather than looking only at the most recent NHS employment.
This can be particularly useful when a career transition occurs close to the end of the tax year.
Starting Early Makes Career Changes Easier to Document
The earlier doctors organise their records, the easier it becomes to identify anything missing.
After leaving an NHS position, it can be sensible to ensure that relevant employment documentation has been retained. When starting a new role, the same process can be repeated.
The result is a continuous record covering the whole tax year.
This approach also reduces the pressure associated with preparing Self Assessment shortly before the filing deadline.
Looking at the Whole Tax Year
A doctor’s current job represents only part of the financial story when employment has changed during the year.
The relevant period may include an old NHS position, a new NHS position and several additional professional activities.
Viewing the year as one complete financial period makes it easier to understand why keeping records from every stage of a career transition matters.
It also provides a clearer foundation for preparing the eventual Self Assessment return.
Conclusion
Changing NHS employers is an ordinary feature of medical careers, but it can create additional financial administration.
Doctors may need to bring together employment records from more than one organisation while also accounting for locum work, private practice, teaching or other professional activities.
Keeping P45s, P60s, payslips, income records and relevant expense documentation organised by tax year can make the process significantly more manageable.
The key is not to wait until the Self Assessment deadline to reconstruct the year. By maintaining records throughout an employment transition and reviewing the complete financial picture, doctors can approach their tax return with much greater clarity.
For medical professionals whose careers involve regular changes in employment, good tax administration can be treated as another part of maintaining an organised professional life.
