Is £500/day inside IR35 a good rate?
Yes, it puts you in the top 5% of UK earners. However, the effective tax rate is high due to the £100k Personal Allowance taper.

Legally the employer (Agency/Umbrella), but your contract rate is usually inclusive of these costs, meaning it comes out of your gross £500.
Can I claim expenses?
Generally no. Under IR35, travel and subsistence from home to work are not tax-deductible.
How much is £500/day monthly?
On average, it yields approx. £5,500 to £5,800 net per month after all UK taxes.
