Quick definition (read this first):
CF411 is used to apply for (or transfer) Home Responsibilities Protection (HRP) for full tax years between 6 April 1978 and 5 April 2010.
CF411A is used to apply for or transfer National Insurance (NI) credits for parents and carers for periods from 6 April 2010 onwards.
The simplest way to think about it
- If the missing years are 1978–2010 → you’re in HRP territory → CF411.
- If the issue is after 6 April 2010 → you’re in NI credits territory → CF411A (if you meet the CF411A rules).
- The missing tax year(s) is the key — check your NI record first.
CF411 vs CF411A (quick comparison)
- CF411 → HRP (1978–2010) / missing HRP years
- CF411A → NI credits (post‑2010 context) and related credits
Which should I use? (one clear decision section)
Use this decision rule:
- Step 1: Check which tax years are missing on your NI record.
- If the missing years are between 1978 and 2010 → use CF411 (HRP).
- If the issue is from 6 April 2010 onwards → check CF411A (NI credits) and follow the CF411A guidance.

Common mistakes (why people download the wrong form)
- Mixing up the dates: HRP is 1978–2010. If your gap is in the 1980s or 1990s, CF411A won’t fix it.
- Assuming CF411A is the ‘new version’ of CF411 — it isn’t. They do different jobs (HRP vs post‑2010 credits).
- Downloading forms before checking the NI record. Most confusion disappears once you mark the years that aren’t full.
- Using the right form but not mapping evidence year-by-year. HRP is assessed against full tax years, so clarity helps.
