Every doctor and dentist knows the tax year ends on April 5th, but far fewer know exactly what actions to take before that date. This Tax Year-End Checklist for Doctors gives you a clear, simple guide to protecting your income, cutting unnecessary tax, and setting yourself up for a stronger financial year ahead.
Recently, Dr. Ayo, an NHS GP with a growing side income from health tech consulting and locum shifts, shared his frustration:
“Why did nobody tell me this sooner? It’s a bit late now.”
He’d been missing out on legitimate tax reliefs for years, operating as a sole trader instead of through a limited company, never checking his Adjusted Net Income, and claiming none of his professional expenses. Thousands lost, completely avoidable.
The good news: there’s still time. With just weeks left until April 5th, these seven steps can make a real difference.
Know Your Adjusted Net Income (ANI)
Your Adjusted Net Income (ANI) isn’t just your basic salary. It’s your total taxable income after deductions, and it determines nearly everything – from personal allowance reductions to high‑income child benefit charges.
Most medics miss this number because their accountants only send summary figures. Yet understanding your ANI helps you make strategic decisions like when to contribute to pensions or donate to charity.
You can learn more about ANI in our detailed guide on Adjusted Net Income for Doctors.
Consider Incorporating a Limited Company
If you earn meaningful income outside your NHS work – from private practice, consulting, or medical reports, running those activities as a limited company can save you thousands in taxes while offering liability protection.
Many doctors start as sole traders without realising that higher tax rates and limited expense flexibility quickly make this setup inefficient. Incorporating can also unlock better pension and investment planning opportunities.
Before making the switch, speak with an accountant who understands medical income streams and NHS pension rules.
Use Pension Contributions Strategically
Your NHS pension is valuable, but topping it up or contributing to a SIPP (Self‑Invested Personal Pension) — can reduce your ANI and help you dodge the notorious 60% effective tax trap when income crosses two key thresholds.
Better still, unused allowances from the last three years can still be carried forward. If you’ve not maximized them, now is your chance.
In a world where doctors often pay full tax but receive fewer benefits, your pension remains one of the most powerful financial levers available.
Open or Max Out Your SIPP
Every £100 you put into a SIPP is boosted by roughly £50 in tax relief if you’re a higher‑rate taxpayer. That’s free money before you even consider investment growth.
Over time, a well‑managed SIPP can become your primary long‑term investment vehicle, giving you freedom from NHS caps and control over growth strategies.
The key: act before April 5th. Contributions made after that date count toward the next tax year. Don’t leave it for “someday.”
Use Your ISA and LISA Limits
ISAs remain the simplest, most flexible tax‑free investment account available. Doctors should fill their £20,000 ISA allowance before midnight on April 5th — it doesn’t roll over. If you qualify for a Lifetime ISA (LISA), you also get a government 25% bonus up to £1,000 each year.
These small steps compound into major long‑term advantages when combined with careful pension planning. A few clicks now can save you thousands down the road.
Claim Every Professional Expense
You can claim GMC fees, indemnity insurance, Royal College dues, mileage, exam costs, and professional subscriptions for up to four years back.
Hundreds of doctors I’ve spoken with have never claimed a penny of this, simply because no one told them they could. The process isn’t complicated, especially once you’ve identified legitimate expenses relevant to your medical role.
Check Your Tax Code Now
This one takes five minutes but could uncover years of overpayment. Your tax code tells HMRC how much to take from your salary. The wrong code can cost you hundreds or even thousands annually.
Doctors juggling multiple income streams (NHS salary, locum work, private consulting) often end up with misapplied codes. Correcting them is straightforward but time‑sensitive: do it before the year closes to apply any refunds faster.
Avoiding Common Traps for Medical Professionals
Many well‑earning clinicians unknowingly fall into higher tax bands due to threshold creep and unclaimed deductions. Our breakdown on the 60% Tax Trap for Doctors explains why effective planning, not just accounting, is key.
These traps are stealthy. They rarely trigger alarms until after your window to act has closed. A few simple calculations can change your tax results dramatically.

Take Action Before the Clock Runs Out
None of these actions require deep financial expertise. They only require awareness and timely execution. The difference between paying “what’s due” and overpaying year after year is often just knowledge.
So, with only a few weeks left in the tax year, pick two or three things from this checklist today. Even small steps such as updating your tax code, filling your ISA, or claiming old expenses can make a significant impact.
It’s not too late to make this your most financially efficient year yet.
