Understanding Tax & Accommodation for Contractors in Suffolk
Working on significant infrastructure projects in Suffolk brings specific considerations, particularly regarding your tax obligations and the expenses you can legitimately claim. For contractors, understanding HMRC's rules on travel, subsistence, and accommodation is crucial for maximising your take-home pay and ensuring compliance.
For the vast majority of contractors, a large local construction site is considered a "temporary workplace". This distinction is key to understanding what expenses are allowable. Generally, a workplace is considered temporary if you expect to spend, or have spent, less than 40% of your working time there over a period not exceeding 24 months.
The 24-Month Rule and its Impact
Under HMRC's "24-month rule," if you know from the outset that your contract in the Sizewell area will last more than 24 months, or if at any point it becomes clear it will, your accommodation near the project site may cease to be considered an allowable expense. The same applies if you spend (or expect to spend) more than 40% of your working time at a single worksite for a continuous period exceeding 24 months. If this rule is triggered, the workplace is no longer considered "temporary" for tax purposes, and therefore normal commuting and associated living expenses become non-deductible.
For many contractors working on local projects, contracts are often structured to align with specific project phases, which may fall within or outside this 24-month window. It's vital to keep accurate records of your contract duration and any extensions.
Allowable Expenses: Travel, Accommodation & Subsistence
When your assignment in the local area is at a temporary workplace, you can typically claim tax relief on certain essential costs incurred wholly, exclusively, and necessarily in the performance of your duties. These generally fall into three categories:
- Travel Costs: This includes mileage for using your own vehicle (HMRC's Approved Mileage Allowance Payments – AMAP rates currently 45p per mile for the first 10,000 miles, then 25p thereafter for cars and vans in 2026), public transport fares (trains, buses), and taxi fares if necessary.
- Accommodation Costs: Reasonable expenses for overnight stays away from your permanent home are usually allowable. This covers rent for a serviced apartment or house, utility bills, council tax, and even reasonable cleaning costs. This is where providers like Sizewell Stays become invaluable, offering all-inclusive packages that simplify expense tracking.
- Subsistence Costs: This includes reasonable costs for food and drink while you're working away from your usual home. HMRC doesn't provide specific daily allowances for subsistence, but rather expects claims to be "reasonable." Keeping receipts is always advisable.
Simplified Expenses vs. Actual Costs
While keeping meticulous records and claiming actual costs is always an option, some contractors may opt for simplified expenses for certain outgoings like business mileage. However, for accommodation, claiming actual costs is almost always more beneficial due to the higher values involved.
IR35 and its Interplay with Expenses
It's important to note the interaction between your IR35 status and expense claims. If you are operating inside IR35 and are deemed an "employed for tax purposes" contractor, your ability to claim expenses directly through your limited company or as a sole trader is significantly curtailed. In such cases, expenses would typically be claimed back through your payroll in the same way as a permanent employee, potentially losing some tax efficiency. If you are working outside IR35, the rules regarding allowable expenses for temporary workplaces as outlined above generally apply.
