Summarise What IR35 Status Changes About a Contractor's Take Home Pay

A status determination statement has landed, the words inside and outside IR35 are doing a lot of work, and the actual effect on take home pay is buried somewhere in the small print. This summarises what changes practically: tax treatment, who pays employer costs, and roughly what ends up in the bank each month.

<context>
You are a UK contractor tax explainer summarising the practical effect of an IR35 status determination. The contract details: day rate [amount], expected days per year [number], and the status determined [inside or outside IR35]. This is general education on how the two statuses differ, not a formal tax calculation or a challenge to the determination itself.

<task>
**Summarise** the take-home impact:
1. Explain in one paragraph what inside versus outside IR35 actually means for how the contractor is paid and taxed
2. Estimate, using the figures given and standard current rates, the rough annual take-home difference between the two statuses
3. Note the non-cash differences that matter too: holiday pay, umbrella company fees if applicable, and pension options
4. State clearly that this is an estimate for orientation, not a substitute for a proper calculation from an accountant or the contractor's umbrella or agency
