From day rate to take-home pay: a contractor's guide (2026/27)
Last updated: 6 April 2026
In short
To estimate take-home from a day rate, first work out your annual billing (day rate x billable days, typically 220–230 a year after holiday, illness and gaps), then deduct tax. Through a limited company outside IR35 you pay Corporation Tax then Income Tax on a low-salary-plus-dividends mix; through an umbrella you're taxed like an employee (Income Tax plus National Insurance). Umbrella take-home is usually lower for the same rate.
A day rate looks great on paper — £500 a day sounds like £130,000 a year. But nobody bills 260 days, and tax takes a real slice. This guide shows how to get from a day rate to a realistic annual take-home figure for 2026/27, and why the limited-company vs umbrella choice matters so much.
Step 1: how many days will you actually bill?
There are around 260 working weekdays in a year, but you won’t invoice all of them. Subtract:
- Holiday — say 5–6 weeks (25–30 days)
- Bank holidays — 8 days
- Illness, admin and training — a handful of days
- Gaps between contracts — the big one; even good contractors have quiet weeks
A realistic 220–230 billable days is a sensible planning assumption for a full year. At £500/day, 225 days is £112,500 of billing — not £130,000. Always sanity-check a rate against days you’ll genuinely invoice.
Step 2: choose your structure
How you’re engaged changes the tax completely:
- Your own limited company (outside IR35): the company bills the client, pays Corporation Tax on its profit, and you extract money as a low salary plus dividends. This is usually the most tax-efficient route — dividends are taxed at just 10.75% in the basic-rate band for 2026/27, with no National Insurance.
- Umbrella company: you become an employee of the umbrella. Your rate flows through PAYE, so you pay Income Tax and National Insurance like any employee, and employer’s costs are typically deducted from the assignment rate too. Simpler and admin-free, but take-home is generally lower.
- Inside IR35 via your own company: taxed close to employment regardless of the company wrapper, so the efficiency of dividends largely disappears.
Step 3: the taxes that come out
For 2026/27, the figures that shape your take-home are:
| Item | 2026/27 |
|---|---|
| Personal allowance | £12,570 |
| Basic-rate band top | £50,270 (20% Income Tax below) |
| Higher rate | 40% to £125,140, then 45% |
| Employee NI | 8% (£12,570–£50,270), 2% above |
| Employer NI | 15% above £5,000 |
| Dividend rates | 10.75% / 35.75% / 39.35% (after £500 allowance) |
The personal allowance also tapers away once total income passes £100,000, which quietly pushes high earners into an effective 60% band on that slice — something a £600+ day rate can reach.
A rough worked sketch
Take a £450/day contractor billing 225 days = £101,250 through their own company, outside IR35:
- Deduct allowable costs and a small salary; the company pays Corporation Tax on the profit.
- The director draws a £12,570 salary plus dividends, with much of the dividend income taxed at 10.75% up to the £50,270 band and 35.75% above it.
- The result is a take-home materially higher than the same rate run through an umbrella, where the whole amount is taxed as employment income.
The exact figure depends on your costs, pension contributions and whether you’re inside or outside IR35 — which is why it’s worth modelling rather than guessing. Our take-home calculator turns a day rate into an annual take-home estimate for both limited and umbrella routes.
Things that change the answer
- IR35 status — inside vs outside can swing your take-home by thousands. See our IR35 calculator.
- Pension contributions — employer contributions from your company are a deductible cost with no NI or dividend tax, often better than drawing higher-rate dividends.
- Expenses — genuine business costs (equipment, software, some travel) reduce taxable profit.
- Other income — a partner’s salary, rental or a second contract fills your bands first.
The takeaway
Don’t judge a contract on the headline day rate alone. Multiply by realistic billable days, pick the right structure, and model the tax before you commit. A lower day rate outside IR35 can beat a higher one inside it.
