5 free questions on Self-employed, voluntary and planning NICs, part of learning outcome 1 (The UK tax system). Pick an answer to check it, or open the answer to see why each option is right or wrong.

  1. Question 1 of 5

    Edwin is self-employed with profits of £30,000 in 2026/27. What is his class 2 position?

    Show answer

    The answer is C: Class 2 is treated as paid without him paying anything

    Self-employed people with profits of £7,105 (the small profits threshold) or more are treated as having paid class 2, so they keep access to contributory benefits without paying.

    Why the other options are wrong

    A
    Above the small profits threshold, class 2 is deemed paid.
    B
    High profits give a deemed credit, not a loss of one.
    D
    Class 2 is a flat rate, and here it's deemed paid.
  2. Question 2 of 5

    Last year Ali made a trading loss of £4,000, which he set against his other income for income tax. This year his trading profit is £30,000. On what profit is class 4 charged this year?

    Show answer

    The answer is A: £26,000

    For class 4, a trading loss relieved against non-trading income for income tax can still be carried forward against later trading profits: £30,000 − £4,000 = £26,000. Class 4 is then 6% of the amount above £12,570.

    Why the other options are wrong

    B
    That deducts the £12,570 limit and ignores the loss brought forward.
    C
    A loss used against other income can still be carried forward for class 4.
    D
    A loss reduces profits; it isn't added to them.
  3. Question 3 of 5

    When is voluntary class 2 for 2026/27 due through self assessment?

    Show answer

    The answer is A: 31 January 2028, in one sum

    Voluntary class 2 is collected through self assessment, with the full amount due on the following 31 January (31 January 2028 for 2026/27). No payments on account are needed.

    Why the other options are wrong

    B
    It's due on the 31 January after the tax year.
    C
    Class 2 isn't included in payments on account.
    D
    Under self assessment it's paid as one sum.
  4. Question 4 of 5

    Which statement about class 3 contributions is correct?

    Show answer

    The answer is C: They can be paid up to six years late, at the rate for the year of payment

    Class 3 fills gaps in years with too few contributions. It can be paid up to six years later, at the rate for the year of payment, but not for the year State Pension age is reached or later.

    Why the other options are wrong

    A
    Late payments use the rate for the year they're paid.
    B
    They're only for years with insufficient contributions.
    D
    They can't be paid for that year or later.
  5. Question 5 of 5

    A business owner employs his wife at £10,000 a year. What is the NIC position?

    Show answer

    The answer is A: She pays no NICs but still builds State Pension entitlement

    Pay between the LEL (£6,708) and the primary threshold (£12,570) earns State Pension credit without employee NICs. Employer NICs are due on the part above £5,000, and the salary must be justified by the work done.

    Why the other options are wrong

    B
    Employer NICs are due on pay above £5,000.
    C
    Employees pay nothing below the primary threshold of £12,570.
    D
    Her pay is below the primary threshold, so she pays nothing.
