As of 13 August 2026, AI can only partly claim pension contributions on your tax return.

This still needs a person who signs their name to it.

If this goes wrong, you claim the wrong pension amount or treatment and may need to correct the return or deal with HMRC consequences.

What to actually do

  1. Hand it to a person

    The route this page recommends

    A person who owns the outcome does this end to end, worth it when the failure is dear.

  2. Use a tool built for this

    Second choice
  3. Do it yourself

    The distant third

    A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

    How to actually do it

    1. Open your pension provider statements, payslips, P60 and any Self Assessment records for the relevant UK tax year.
    2. Copy the contribution totals, dates, scheme type and payment method into the prompt, keeping personal and employer contributions separate.
    3. Paste the completed prompt into a chatbot and ask it to identify missing evidence, duplicate figures and unresolved scheme details.
    4. Compare every amount in the chatbot's reconciliation table with the original pension statement and payroll documents.
    5. Open the relevant GOV.UK pension tax relief and Self Assessment guidance, then check each proposed treatment against the current wording and your tax year.
    6. Ask your pension provider to confirm how the contributions were treated for tax if the statement or payment method is unclear.
    7. Enter only figures and sections you have confirmed in HMRC's Self Assessment service, and ask a tax adviser or accountant to check a serious or disputed case before submission.

    Prompt

    Help me prepare, but not submit, the pension contribution section of my UK Self Assessment tax return.
    
    Tax year: [tax year]
    Pension provider and scheme type: [details]
    How the contributions were made: [relief at source, workplace payroll, salary sacrifice, net pay arrangement, or unknown]
    Total contributions shown on provider statements: [amount and currency]
    Contributions shown on payslips or P60: [amount and currency]
    Employer contributions, if shown: [amount and currency]
    Any contributions paid after the tax year ended but intended for an earlier tax year: [details]
    Relevant income details: [brief details]
    
    Use only the information I provide and current GOV.UK guidance that you can identify clearly. Do not invent figures, assume the scheme type, or decide that I am entitled to a relief without explaining what evidence supports it. Separate personal contributions from employer contributions and flag any figures that may be duplicated between my pension statement and payroll records. Produce:
    1. a list of missing documents or facts;
    2. a reconciliation table showing each figure, its source and whether it should be included or excluded from the Self Assessment calculation;
    3. the relevant tax-return box or section only if you can identify it confidently;
    4. a plain explanation of the uncertainty and the exact point I must confirm with HMRC, my pension provider or a tax adviser;
    5. a final checklist for me to complete before I enter anything in HMRC's service.
    Do not submit the return, do not estimate tax, and do not present uncertain treatment as a confirmed answer. This is not professional advice.

FAQ

Can AI calculate tax relief on my pension contributions?
It can organise the figures and show a calculation using the information you provide, but it may apply the wrong treatment if it misunderstands how the contributions were made. Compare the result with your pension statement, payroll records and current GOV.UK guidance before entering it.
Do I need to declare pension contributions on my tax return?
That depends on the type of pension contribution, how it was paid and what has already been dealt with through payroll or the pension scheme. AI can make a document checklist, but it should not decide your entitlement where those facts are unclear.
Can ChatGPT fill in my pension contributions on Self Assessment?
It can draft possible entries and explain which evidence supports them, but it cannot submit the return or take responsibility for the figures. Check the draft against HMRC's current service and ask a tax adviser or accountant about any serious or uncertain case.
Is it safe to use AI for pension tax relief?
It is reasonable to use AI for organising statements and preparing questions, not as the final authority on a claim. This is not professional advice, and a serious case needs a tax adviser or accountant.
