Tax Relief for Working from Home as a Sole Trader or Director

If you run your business from home as a sole trader or company director in the UK, you may be able to claim tax relief on a portion of your household costs. The rules differ depending on whether you operate as a sole trader or through a limited company, and you must follow HMRC guidelines that change from time to time.

This guide explains the two main methods for claiming relief, what qualifies for home office equipment, how council tax fits in, and practical steps to keep records correctly so you stay compliant without overclaiming.

Who can claim working from home tax relief

As a sole trader, you can claim if you use part of your home exclusively for business for a reasonable amount of time each week. Limited company directors usually claim through the company paying them a rent or by claiming expenses personally on their self-assessment. The key is that the space must be used for genuine business activity, not just occasional admin at the kitchen table.

Check current HMRC rules on GOV.UK before claiming, as eligibility criteria and allowable amounts are updated regularly. Both sole traders and directors need to keep evidence that the claim is reasonable and not excessive.

The simplified expenses method

The simplified expenses method lets you claim a flat rate per month based on the number of hours you work from home. This avoids detailed calculations of your actual bills. You simply record the hours worked at home and apply the flat rate for the relevant months.

Keep a diary or timesheet showing dates and hours spent working from home.
Apply the flat rate only to months where you worked more than a set number of hours from home.
You cannot claim this at the same time as actual costs for the same expense categories.

This method is useful for early-stage founders who want to minimise record-keeping. Always confirm the current flat rates and qualifying hours on GOV.UK, as they can change.

The actual cost method

With the actual cost method you calculate the exact proportion of your household bills that relate to business use. This usually produces a higher claim but requires more detailed records and calculations. You work out the percentage of your home used for business, then apply that percentage to relevant bills.

Measure the floor area of the room or rooms used for business and divide by the total floor area of the house. Multiply the resulting percentage by the business-use time proportion if the space is also used personally. Apply this to allowable costs such as heating, electricity, internet and mortgage interest (for sole traders). Limited companies handle this differently and often reimburse the director.

Keep copies of all bills and a clear calculation spreadsheet. HMRC may ask for evidence, so make sure your workings are transparent and based on reasonable usage patterns.

Claiming for home office equipment

You can claim capital allowances or deduct the cost of equipment bought specifically for business use in your home office. This includes desks, chairs, computers, monitors, printers and shelving. Items used solely for business can usually be claimed in full or depreciated according to current capital allowance rules.

If an item is used for both business and personal purposes, you must apportion the cost on a reasonable basis. Keep receipts and record the date of purchase, description and business percentage. For sole traders this often goes through your self-assessment tax return. Directors may have the company purchase the equipment directly where appropriate.

Review the latest capital allowances information on GOV.UK each tax year, as thresholds and rates are subject to change. Avoid claiming on furniture or fittings that are mainly for domestic use even if occasionally used for work.

Council tax and other household costs

Council tax is generally not claimable if you work from home, because business rates may apply instead if you designate part of the house as commercial space. Most home-based sole traders and directors do not claim council tax relief to avoid triggering a business rates assessment that could increase costs significantly.

Other household costs such as water rates are rarely claimable unless your business use demonstrably increases consumption. Mortgage interest (sole traders only), rent, heating, lighting, insurance and broadband are the most common claims under the actual cost method. Always use a fair and consistent method of apportionment and be prepared to explain your reasoning if queried.

Never claim the full amount of any household bill. Overclaiming can lead to corrections, penalties or loss of credibility with HMRC. Document your reasoning clearly in your records each year.

Record keeping and common pitfalls

Maintain a dedicated folder or digital file for home-working claims. Include floor plans, utility bills, equipment receipts, timesheets and your calculation notes. Update records every quarter rather than leaving everything until self-assessment time.

Common mistakes include claiming 100 percent of a bill, using the simplified method and actual costs together for the same categories, and failing to distinguish between sole-trader and limited-company rules. Directors should consider whether it is more tax-efficient for the company to pay them rent for the office space or to claim directly. Seek professional advice if your turnover grows or your working pattern changes.

Review the latest guidance on GOV.UK and the Companies House website each year. Rules on what constitutes a home office, allowable deductions and reporting requirements can be updated without much notice.

Putting it into practice at an early stage

When you are just starting out, choose the simplified expenses method if your records are limited and your home use is straightforward. As your business grows and you invest in dedicated equipment, switch to the actual cost method if the numbers justify the extra administration. Test both approaches for one tax year using your real figures before deciding which works best for you.

Founders based at Loomworks in Liversedge benefit from a formal workspace address, which can simplify some of these considerations while still allowing legitimate claims for any additional home working. Keep your claims proportionate, document everything, and revisit your approach each year as your business and HMRC rules evolve.

Frequently asked questions

Can I claim both simplified expenses and actual costs in the same tax year?

No. You must choose one method for each category of expense. Switching mid-year or mixing the two for the same costs is not permitted. Choose the method that best suits your record-keeping ability and likely claim size, then apply it consistently for the full tax year.

Do limited company directors claim differently from sole traders?

Yes. Sole traders claim directly on their self-assessment. Directors usually have the company reimburse them for home office costs or pay a commercial rent. The company must follow different rules on what it can deduct as a business expense. Always confirm current treatment on GOV.UK.

Is council tax ever claimable when working from home?

In most cases it is not advisable. Claiming council tax relief can trigger a business rates assessment on part of your property, which often costs more than any tax relief gained. Most home-based businesses therefore exclude council tax from claims.

What records do I need for home office equipment claims?

Keep purchase receipts, a note of the date bought, a description of the item, its business use percentage and how you calculated that percentage. For items over certain values you may need to claim capital allowances rather than immediate deduction. Retain these records for at least six years.

How often should I update my home working calculations?

Review your floor area percentage and usage patterns at the start of each tax year and whenever your working arrangements change significantly. Minor weekly fluctuations do not usually require recalculation, but a permanent change in the space used or hours worked should be reflected in your records.
