Also there are a lot of fintechs (or pure finance) that will pay more than that. I'd say after about £160k you're going to struggle without moving into some kind of management type of position, though, if you're not at a FAANG or extremely well funded startup.
Also bay area COL is substantially higher than London. I live in a 4 bed house a 30 min cycle from the City (where I work), and pay around £1500/month.
Or being a fairly experienced / niche contractor who can get £600+ a day - although that obviously forfeits the job security and benefits (but then is an actual £160k+, not £N+ with intangibles to bring it up.)
- Pay yourself minimum wage (0pct rate) ~£9K/year. - You can probably write off around £10K against tax (lunch, transport) - Pay 19% corporation tax on the rest - Pay yourself a dividend up to upper rate, end up paying around 7.5% tax on that - ...probably some other tricks
Leads to a total tax rate of around 20-25% as long as you can survive on £50K a year. So net income something like £115K after tax. Say £9.5K/month, would require a gross salary of £194K [0].
This is why the government is trying to clamp down on IR35 abuse, but still plenty of contracts outside, at the moment.
Although there is a risk here that HMRC will come after you at some future point when this has been ruled an invalid scheme. Personally I don't think it's worth it and don't tax dodge/minimise/optimise (also a moral stance.)
