Trading Losses and National Insurance
Loss relief choices and NIC consequences for business owners, workers and companies.
How to study the ATT Qualification
Use Finance Act 2025 for the 2026 tax papers, complete the three foundational CBEs early, apply professional ethics throughout and concentrate option practice on the one paper you will enter.
Core concepts
Concept 1
Loss-relief claims differ by claimant, period, income source, carry direction and restriction.
Exam cue: Identify who made the loss and list legally available claims.
Concept 2
The best claim depends on tax saved, timing, capacity and preservation of other reliefs.
Exam cue: Compare tax outcomes across periods before recommending.
Concept 3
NIC follows status, earnings or profits and can affect both business and individual cash flow.
Exam cue: Separate owner, employee and employer NIC liabilities.

Memory anchors
Loss owner
The person or company making the loss determines the relief route.
Claim order
Check current, prior, carry-forward and gains-related reliefs as applicable.
Restriction
Apply caps, ownership or continuity restrictions before quantifying benefit.
Cash value
Compare tax saved and timing, not nominal loss alone.
NIC map
Identify worker status, class, payer, base and period.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
