£775 a day inside and outside IR35

Where £170,500 goes inside IR35

The umbrella company takes its costs out of the day rate before it pays you a salary through PAYE.

Where £170,500 goes outside IR35

Your company pays you a £12,570 salary, pays Corporation Tax on the profit and pays out what is left as dividends.

£775 a day by days worked

Take-home per year. Fewer billable days means less income but also a smaller share lost to higher-rate tax.

What permanent salary this is worth

An employee would need a salary of about £147,317 to match the inside IR35 take-home, and about £151,245 to match outside IR35. That ignores holiday pay, sick pay and employer pension, which a permanent job adds on top.

The £100,000 trap inside IR35

Your umbrella salary of £147,316 is over £100,000, so you lose £1 of Personal Allowance for every £2 above it. Paying into a pension through the umbrella's salary sacrifice scheme brings that income down and gets back the tax-free allowance.

Corporation Tax marginal relief

The company makes £155,295 profit, which sits between £50,000 and £250,000. The first £50,000 is effectively taxed at 19% and the rest at 26.5%, giving a total Corporation Tax bill of £37,403.

Dividend tax outside IR35

Your salary and dividends add up to £130,461, so £74,870 of the dividends fall in the higher-rate band and are taxed at 35.75%. Dividend tax comes to £36,002, paid through Self Assessment by 31 January after the tax year ends.

In Scotland

Inside IR35 a Scottish taxpayer takes home £84,013, £5,851 less than in the rest of the UK, because the umbrella salary is taxed at Scottish rates. Outside IR35 the difference is £40, because the tapered allowance puts part of the salary into Scottish tax bands.

What one more day is worth

Billing one more day at £775 adds about £353 to your take-home inside IR35, 46% of the day rate, because the top of your umbrella salary is in the additional-rate band. Outside IR35 it adds about £345 (45%), with your top slice of dividends in the same band. So an extra day is worth almost the same either way.

The gap per day billed

The £2,082 gap works out at £9.46 for each day you bill. That equals about 2.7 days' billing at £775: less than one working week of work a year. At £800 a day it narrows by £72 to £2,010.

The next tax threshold

Your umbrella salary inside IR35 is already over £125,140, so there is no higher band to reach. Your salary plus dividends outside IR35 is already over £125,140, so there is no higher band to reach.
