For Engineers
Accountant for Engineers
Fixed fee accounting and tax support for contract and self employed engineers across civil, mechanical, electrical and process disciplines. IR35 status, CIS, and travel between sites, handled properly.
We work with engineers contracting across construction, energy, manufacturing and infrastructure projects, whether you work through your own limited company, as a sole trader, or a mix of contract and CIS work. Beyond annual accounts, we help you understand your IR35 status, claim every travel and professional cost, and plan tax around project based income. Fixed fees, real accountants, no jargon.
How We Help
Accounting built around contract engineering work
IR35 status reviews
We help you understand whether each contract sits inside or outside IR35, and what that means for how you’re paid and taxed.
CIS deductions where relevant
If some of your work falls under the Construction Industry Scheme, we make sure deductions are correctly recorded and reclaimed.
Travel between sites
Mileage and travel costs between different project sites are recorded correctly, distinct from your normal commute.
Professional body subscriptions
ICE, IMechE, IET and similar membership fees, along with CPD course costs, are all captured as allowable expenses.
Limited company or umbrella
We explain the real difference in take home pay and admin between running your own company and using an umbrella, based on your actual contracts.
Year round advice
Real accountants who pick up the phone when an IR35 or expenses question comes up mid project, not just at year end.
Tax Planning For Engineers
What matters most for contract engineers right now
IR35 and off payroll working
Since April 2021 many medium and large end clients determine your IR35 status. We help you understand each determination and what it means for your take home pay.
CIS and the domestic reverse charge
Engineers working on construction projects may fall under CIS and VAT’s domestic reverse charge. We make sure both are handled correctly.
Salary vs dividends inside a limited company
If you’re outside IR35 and run your own company, the right mix of salary and dividends can materially change your tax bill. We review this every year.
R&D relief for innovative engineering work
Genuinely novel design or process engineering work may qualify for R&D tax relief. We flag this where it’s relevant to your projects.

Common questions from engineers
Can you tell me if my contract is inside or outside IR35?
We can review your contract and working practices and give you our view, though for engagements caught by the off payroll rules the end client usually makes the final determination.
Some of my work is CIS and some is straight contracting, can you handle both?
Yes, we regularly work with engineers who have a mix of CIS and standard contract income within the same company.
Can I claim travel between different project sites?
Yes, travel between temporary workplaces is generally allowable, and we’ll confirm what applies to your specific work pattern.
Do you understand professional body subscriptions like ICE or IET?
Yes, we regularly claim these for engineering clients along with related CPD and training costs.
