Limited company vs umbrella: structure guide 2026/27

The core trade-off

Working through your own limited company typically retains more take-home than an umbrella at most contractor day rates. The gap exists because the company can pay you as a combination of salary and dividends, with dividend income taxed at lower rates than employment income. However, the limited company route carries running costs (accountant, company filings, bank account), administration time and, critically, the obligation to correctly assess and comply with IR35 for each engagement.

The umbrella route is simpler: you are employed by the umbrella company, all employment tax and NIC is operated by them, and you receive one payslip. The trade-off is that the employer NIC (15% above GBP5,000), apprenticeship levy (0.5%) and umbrella margin all come out of your assignment rate before you see any pay.

What the model calculates

The spreadsheet model takes the same GBP day rate and applies it to both routes.

For the limited company it calculates: turnover (day rate x days), employer NIC on the director salary, profit before tax, corporation tax (including marginal relief between GBP50,000 and GBP250,000 profit), distributable dividends, personal tax on salary and dividends, employee NIC, and net take-home.

For the umbrella it calculates: the pot available after the margin, the gross salary after employer NIC circularity is resolved, PAYE income tax, employee NIC, and net take-home.

The net benefit line is the limited company net take-home minus the umbrella net take-home, then minus your estimate of limited company running costs (account fees, bank account, registered office and so on). A positive net benefit means limited suits you at your rate; negative means umbrella is ahead after costs.

Running costs matter

The raw take-home gap (before fees) at a GBP500 day rate is typically GBP1,900 to GBP2,000 for 240 days. Accountant fees for a contractor limited company typically run GBP1,000 to GBP3,000 a year depending on the level of service. At GBP2,000 fees the net benefit at GBP500 per day is roughly neutral. At GBP600 or GBP700 per day the raw gap is substantially wider and limited company wins clearly.

The model uses a GBP2,000 default for running costs. Adjust this to reflect your actual quote from an accountant, plus any bank account charges.

IR35 exposure

Limited company operation requires you to assess IR35 status for each engagement. For public sector and medium/large private sector clients (Chapter 10 rules), the fee-payer makes the determination and you have limited control. For small-client engagements you remain responsible for your own status assessment. An inside IR35 determination removes most of the take-home advantage of a limited company, because the deemed payment is subject to full PAYE. If your work pattern involves frequent inside IR35 engagements, the umbrella's simplicity may outweigh the tax difference.

April 2026 umbrella reform

The government enacted the joint-and-several liability (JSL) provisions for umbrella companies as part of the Finance Act 2026 alongside accompanying regulations. From 6 April 2026, where an umbrella company fails to account for PAYE and NIC on contractor pay, the liability can transfer to the agency or (as a last resort) the end client in the labour supply chain.

For contractors, the practical effect is that compliant FCSA or APSCo member umbrellas have become the de facto standard for agency-placed work. Non-compliant or offshore umbrella schemes carry heightened risk as the liability structure incentivises agencies to check compliance. If you are asked to accept a higher take-home via an umbrella scheme that avoids employer NIC, this is very likely a disguised remuneration arrangement carrying both income tax and penalty exposure.

When umbrella makes sense

Umbrella is often the right structure when: the engagement is inside IR35; your day rate is relatively low (the raw take-home gap may not cover accountant fees); the work is short-term or the next engagement is uncertain; you want zero administrative overhead; or the agency requires umbrella for compliance reasons.

When limited company makes sense

Limited company is often the right structure when: you have a genuine outside IR35 engagement with a well-documented business case for the status; your rate is high enough that the take-home gap comfortably exceeds running costs; you plan to work consistently for the medium term; you want control over timing of drawings and pension contributions; or you have other business activity that benefits from the limited structure.

Using the model

Enter your day rate, billable days, director salary (GBP12,570 is typical for a single-director PSC to avoid NIC while retaining state pension entitlement), allowable expenses, umbrella margin, and your estimate of annual limited company running costs. The model derives the raw gap and net benefit. Adjust any input to test the break-even point for your situation.

The model is a directional planning tool. The net benefit calculation assumes you qualify for and correctly operate outside IR35. A specialist can review your working arrangements and confirm the appropriate structure for your contracts.
