Umbrella Company Expenses & SDC: What UK Contractors Need to Know
Navigating the Expense Maze as a UK Contractor
Picture this: You’re a contractor chasing project deadlines, juggling contracts, and somewhere between the paperwork and the hustle, you hear about umbrella company expenses and SDC. For many, these acronyms trigger confusion, but understanding them is vital to ensuring every hour you work is properly rewarded—and that you stay compliant with HMRC.Let’s unravel the complexities together, blending real-world experiences with the most up-to-date guidance. This journey could mean the difference between maximising your take-home pay and facing unexpected tax bills.
What Are Umbrella Company Expenses?
Umbrella companies act as intermediaries between contractors and end clients, handling payroll, taxes, and sometimes expenses. The appeal for many UK contractors is simplicity: you work, submit your timesheet, and the umbrella company manages everything else.But when it comes to claiming expenses—travel, subsistence, equipment—things get tricky. Since 2016, HMRC rules have tightened, especially for those caught by SDC (Supervision, Direction, or Control).
SDC: The Game-Changer
SDC stands for Supervision, Direction, or Control. It’s HMRC’s lens for determining whether you’re truly independent or working more like an employee. If your client (or someone in the supply chain) supervises your work, directs how it’s done, or controls your hours and methods, you’re likely under SDC.If you’re under SDC, your ability to claim tax-free expenses through your umbrella company is severely restricted. This means many day-to-day costs are no longer deductible, cutting into your take-home pay.
How Does SDC Apply?
- Supervision: Someone oversees your work to ensure it’s done correctly.
- Direction: You’re told how to complete tasks, beyond just what needs to be done.
- Control: Your work hours, location, and methods are set by someone else.
- Take-home pay: Fewer allowable expenses means more taxable income.
- Compliance: Incorrect claims risk HMRC investigations, penalties, and back taxes.
- Planning: Knowing what you can claim helps you budget accurately and negotiate better rates.
If any of these apply, you’re likely caught by SDC.
Expenses You Can (and Can’t) Claim
Anecdotally, contractors often share stories of confusion: "I used to claim mileage, but now my umbrella says I can’t. Why?" The answer is almost always SDC. Here’s a quick breakdown:| Expense Type | Claimable Under SDC? | Notes |
|---|---|---|
| Travel to site | No | Unless site is temporary & no SDC |
| Meals/Subsistence | No | Same as above |
| Equipment | No | Employer should provide |
| Professional fees | Yes | If wholly, exclusively, necessary |
| Training | Yes | If required for your role |
Why Does This Matter for Contractors?
For UK contractors, every expense claimed or lost directly affects your bottom line. Here’s what’s at stake:“I was shocked when my umbrella told me I couldn’t claim my train tickets anymore," recalls Sarah, a project manager from Manchester. "It made me rethink which contracts to take."

3. Keep Records: If you can claim, keep receipts and logs. HMRC may request evidence years later.
4. Negotiate Rates: If you’re under SDC and can’t claim expenses, consider negotiating a higher rate to offset lost deductions.
5. Stay Informed: HMRC guidance evolves. Bookmark trusted contractor resources and review updates regularly.
