Frequently Asked Questions

HMRC's flat rate (Approved Mileage Allowance Payments) for 2025/26 is 45p per mile for the first 10,000 business miles and 25p per mile after that.

To claim it:

• Keep a mileage log recording the date, destination, purpose, and miles for each business journey
• Multiply your total business miles by the appropriate rate
• Include the total in your Self Assessment return as a business expense

You can't claim mileage and actual vehicle running costs at the same time — it's one or the other. The flat rate is usually simpler and works well for most people.

Yes, if you work from home as part of running your business. There are two ways to claim.

The simplified flat rate: HMRC allows a fixed monthly amount based on the number of hours you work from home each month — £10 for 25 to 50 hours, £18 for 51 to 100 hours, and £26 for over 100 hours.

The actual cost method: you work out the business proportion of your household bills (mortgage interest or rent, utilities, broadband, council tax) based on the number of rooms and hours used for work.

The flat rate is simpler; the actual method tends to result in a higher deduction if your bills are significant.

The main things you can't claim are:

• Personal costs such as everyday clothing, even if you wear it for work (unless it's a uniform or protective gear)
• Entertaining clients — HMRC doesn't allow this as a deduction
• Fines and penalties such as parking tickets
• The cost of commuting from home to your regular workplace
• Training that helps you move into a new field rather than improving skills for your current one
• Any mixed-use costs where the personal element can't be separated

If you're unsure whether something qualifies, it's better to ask than to claim it incorrectly.

You can claim any cost that is wholly and exclusively for your business. Common examples include:

• Office supplies and equipment
• Business travel (excluding the commute to a regular workplace)
• Professional fees such as accountancy costs
• Stock and materials
• Software subscriptions used for work
• Marketing and advertising
• A proportion of your home costs if you work from home
• Training directly related to your current trade

The golden rule is that the expense must be genuinely for business use. If it has a personal element, you can only claim the business proportion.

When you inherit a property, you don't pay Capital Gains Tax at the point of inheritance — that's when Inheritance Tax may apply instead.

CGT only comes into play if you later sell the inherited property and it has increased in value since you inherited it.

The gain is calculated from the probate value — the market value of the property at the date of death — not from what the original owner paid for it. So if the property was valued at £300,000 on probate and you sell it for £340,000, your gain is £40,000, not the full increase from the original purchase price.

A few things worth knowing:

If the property was the deceased's main home and you sell it within a certain period, some Private Residence Relief may be available.

If you rent the property out before selling, CGT applies in the normal way from the date of inheritance.

If there are multiple beneficiaries, each person is taxed on their own share of the gain. Our Joint (£449) or Trio (£598) filing options cover all owners in one service.

You must report and pay any CGT within 60 days of completion.

Yes. Selling a rental property that was never your main home will trigger Capital Gains Tax on any gain you make.

The gain is calculated as: sale price, minus estate agent and solicitor fees, minus the original purchase price and buying costs, minus any capital improvements made during your ownership.

The first £3,000 of your gain is tax-free (the 2025/26 annual exempt amount). The rest is taxed at 18% if you're a basic-rate taxpayer, or 24% if you're a higher-rate taxpayer.

If the property was at some point your main home before you rented it out, part of the gain may be covered by Private Residence Relief, which could reduce your bill. This is one of the most commonly missed reliefs on rental property sales.

You must report the sale and pay the tax within 60 days of completion. This is a legal requirement and missing the deadline results in automatic HMRC penalties.

We handle rental property CGT returns regularly. Fill in our CGT form to get started, or message us on live chat.

Yes, but only genuine capital improvements — not general maintenance or repairs.

Capital improvements are works that added value to the property or adapted it for a new use. These include: extensions and loft conversions; a new kitchen or bathroom (if it's an upgrade, not a like-for-like replacement); structural alterations; and building a garage or outbuilding.

What doesn't count: repainting, replacing a broken boiler with the same type, routine repairs, or general upkeep. These are maintenance costs and HMRC doesn't allow them as deductions.

To claim improvements, you need receipts or invoices for the work. If you no longer have all the paperwork, we can work with what's available — but the more evidence you have, the better.

The cost of improvements is deducted from your gain, which can reduce your CGT bill significantly on a property you've invested in over the years.

Include any improvement costs when you fill in our CGT form and we'll apply them in the calculation.

If you own a property jointly, each owner is taxed on their share of the gain individually.

Each owner gets their own annual CGT exempt amount (£3,000 for 2025/26), so between two owners you effectively have £6,000 of gains that are tax-free before any CGT is due.

Each owner's gain is also taxed at a rate based on their own income — so if one owner is a basic-rate taxpayer and the other is a higher-rate taxpayer, they'll each pay a different rate on their share. This can work in your favour if the owners are in different income bands.

Ownership is usually split equally (50/50 for married couples), but if you own the property in unequal shares these should be formally documented to ensure HMRC taxes each person on the correct proportion.

For jointly owned property sales, we offer our Joint filing at £449 (two owners) or Trio at £598 (three owners), which covers the full gain calculation and filing for all owners in one service.

If you're unsure how your ownership is split or how the gain should be divided, message us on live chat or book a call with us.
