Does completing your Self-assessment feel like a rerun of a childhood favourite TV series?!

Paula Veysey-Smith • 24 January 2025

Self-assessment tax, between navigating tax codes, understanding what to include, allowable expenses, and the deadlines, it’s easy to feel like you’re spinning in circles with no clear direction, a bit like being on a Magic Roundabout!  Well with that in mind I’ll hand over to some much loved characters to explain more...


On a sunny day in Tax Meadows, Dougal the dog, Florence, Zebedee, and the gang gathered around to talk about a magical thing called Self-Assessment. 


Boing went Zebedee and said, "Self-Assessment is telling the Tax Gardeners at HMRC about how many seeds you’ve made from the lovely flowers in our magic meadow.  If you’ve made more seeds that you planted you have to pay some of them back to them to  keep the meadow looking lovely!”


Young Florence, who didn’t know much about the Tax Gardeners also asked, "and who has to tell them, don’t they know already?"


Zebedee nodded wisely. “If you have a job, your employer will tell them but if you’re like Ermintrude the cow, selling flowers at the market, or Brian the snail, renting out your shell as a holiday home, you need to do tell them about all the income you earn!”


Dougal wagged his tail, “When do we have to send it to the Tax Gardeners?”  Boing went Zebedee, as he couldn’t contain his excitement at being the Tax Gardeners expert.


“You must file by 31st January and pay the seeds you owe them or they might start blowing dandelion fluff everywhere and we don’t want that!


“Yes, don’t be late," warned Ermintrude, "or they'll send Soldier Sam with a nasty letter!"  Zebedee looked put out that she had butted in and his spring, for once, didn’t boing! Ermintrude continued, pleased to have something better to do than chew the flower in her mouth!


“First, there’s the arrival of a £100 fine—a little like an unexpected boing from Zebedee, but far less delightful. This fine appears whether or not you owe any tax. If you dawdle for three months, you’ll meet another twisty challenge. Now it’s £10 per day, up to a maximum of £900, like being chased, if rather slowly, around the roundabout endlessly by Brian. After six months, an extra 5% of tax owed (or £300, whichever is greater) is added to the dandelion mix.”


The sun had started to set, Florence smiled and said, "So, Self-Assessment isn’t scary—it’s just about telling the Tax Gardeners the truth and helping the meadow thrive!"



"Exactly!" Zebedee laughed. “Be a Brian, start off early, take it slow but steady and you’ll get there in plenty of time. 


Boing when Zebedee one last time, “Time for bed and tomorrow we’ll work on keeping our meadow blooming!”


I hope you enjoyed our visit to the Magic Roundabout, a fun look at Self-assessment tax.  If you haven’t been a Brian please do contact us now and we can wave our magic wand to make your self assessment return go away!

Working from Home Expenses You Can Claim in 2025–26

by Paula Veysey-Smith • 22 May 2025
Do you work from home? If you do, either full-time or part-time, you may be eligible to claim certain expenses either against your own taxes or your Limited Company ones. Many factors will determine what you can claim such as working location, employment status (employee, self-employed, company director), and how much of your home is used for work. What can I claim as an employee of a company? You can claim: A flat-rate allowance of £6 per week (or £26 per month) without needing to provide evidence of expenses. This is the simplest method and can be claimed via your tax code or tax return. The actual costs (if you don't use the flat rate) which can include a proportion of the following: Heating and electricity Internet and phone bills Water (if it’s metered and usage is clearly work-related) You cannot claim rent or mortgage interest unless you're self-employed. These expenses can be claimed via HMRC’s online portal if they have not already been reimbursed by your employer! What can I claim if self-employed (sole trader or via a Partnership)? Here you have two options: 1. Simplified Expenses (Flat Rate) Based on hours you work from home each month: 25–50 hours/month → £10/month 51–100 hours/month → £18/month 101+ hours/month → £26/month 2. Actual Expenses Method You can claim a proportion of: Rent or mortgage interest (not capital repayments) Utilities (gas, electricity, water) Council tax Internet and phone Cleaning and maintenance Home insurance (if work-related) You’ll need to work out the percentage of your home used for business, usually by the number of rooms (not including bathrooms, corridors, storage space) or square footage. One word of warning is never claim the whole use of a room for business as every room will have duality in use. This is also important if you own your home as a room declared purely an office could attract Capital Gains Tax when the property is sold. We suggest that any room should only be claimed at 90% for business. And only one room can be used, not a multiple! These costs should be included on your Self-Assessment tax return. Can I make a claim for these expenses in my Limited Company? Yes, you most certainly can. At MPower Accounting we not only recommend using the actual expenses method as set out above, we provide our clients with a bespoke spreadsheet to calculate these expenses, and others such as mileage, on a month-by-month basis. These amounts can then be claimed as expenses to the Company and paid out to you. It is one of the tax efficient methods of taking money from your business. Capturing and calculating monthly your regular working from home expenses is the best way of ensuring they are recorded correctly. To help you do this we are offering a free download of the spreadsheet usually only available to our clients; please use the link below to get this. Paying taxes is a necessary evil but I am a firm believer in minimising this liability for both individuals and companies. Correctly claiming working at home expenses is one way to reduce your tax bill. Please do contact us if we can help you further identifying all the expenses you can claim and also for further assistance in how to correctly use and populate the downloaded template.

How will I be affected by Making Tax Digital for Income Tax (MTD for ITSA)?

by Paula Veysey-Smith • 23 March 2025
HMRC are starting to send out letters to sole traders and landlords in the initial steps towards Making Tax Digital for Income Tax. If you receive one of these letters do not panic, help is at hand. So let’s answer your most asked questions about Making Tax Digital. What is Making Tax Digital for Income Tax? Making Tax Digital for Income Tax (MTD for ITSA) is a UK government initiative aimed at modernising the tax system. It will require individuals and businesses to keep digital records and submit tax information to HMRC using compatible software. It is part of a broader initiative to digitalise tax returns and follows on from the changes already implemented for VAT reporting. Will Making Tax Digital affect me? MTD for ITSA will affect individuals who: Are self-employed (e.g. sole traders) and/or landlords (earning income from property). Have a total income over £50,000 per year (combined from self-employment and property). Are currently required to complete a Self-Assessment tax return. From April 2026 , MTD for ITSA will be mandatory for those earning over £50,000. From April 2027 , this threshold will reduce to £30,000. What will I have to do if my earnings are over the threshold? You will need to keep digital records for income and expenses which will mean using MTD compatible software. This will be a major change for those of you still keeping paper records. Instead of submitting an annual self-assessment return you will need to submit quarterly updates 4 times a year to HMRC. At the end of the tax year an End of Period Statement (EPOS) and a Final Declaration will need to be submitted which essentially replaces the current Self-assessment return. All of these will be required digitally, paper records and manual calculations will no longer be accepted. This means that instead of 1 annual return you will need to make 6 submissions! So what software do I need to use to keep digital records? Acceptable software include: QuickBooks Xero FreeAgent Sage or, HMRC-recognised spreadsheet tools with bridging software ( not highly recommended ) No more shoeboxes of receipts or manual books — everything must be digitally recorded. When will I need to register for MTD? You’ll need to sign up for MTD for ITSA before April 2026 . This is a deadline and not a target, signing up early is always advisable. HMRC will provide a service for you to do this but having the guiding hand of an accountant will make this a much easier task.

Understanding UK Tax Codes: A Complete Guide

by Paula Veysey-Smith • 13 February 2025
What are these jumbles of letters and numbers? When you start a new job, receive a pension, or change employment, you’ll likely notice a tax code on your payslip. Although, to many, this code looks like a random combination of letters and numbers it is actually the crucial piece of information that determines how much tax is deducted from your income. Understanding your tax code will empower you to check that you’re paying the correct amount of tax and, if necessary, correct the code with HMRC. What is a Tax Code? A tax code is used by your employer or pension provider to calculate how much income tax to deduct from your pay or pension. It’s based on your Personal Allowance (the amount you can earn tax-free each year) and any other factors that affect your tax situation, such as additional income or benefits. For the 2024/25 tax year, the standard Personal Allowance is £12,570 and will remain at this level for the 2025/6 tax year. This means most people can earn up to this amount without paying income tax. Common UK Tax Codes and Their Meanings Common codes can be broken down into three main categories: Standard Tax Codes 1257L: This is the most common tax code for people with one job or pension. It reflects the standard Personal Allowance of £12,570. BR: Stands for Basic Rate (20%). This code is used when all your income from this employment or pension is taxed at the basic rate, usually because you have more than one job or pension and the Personal Allowance has already been used up. D0: This means all your income is taxed at the higher rate (40%). D1: This code applies when all your income is taxed at the additional rate (45%). 0T: Used when your Personal Allowance has been used up, and all your income is taxable. Although similar to BR this code applies to all tax rates (20%, 40% & 45%). Emergency Tax Codes The term ‘Emergency Tax Code’ is often misunderstood. This code is most often used when HMRC does not have the information to calculate the correct tax code for an individual and should be corrected when the information does become available. Usually the code 1257L W1/ M1 is used which means that the Personal Allowance is being applied. The main difference is that tax is calculated on a weekly (W1) or monthly (M1) basis rather than cumulatively. You would most usually see this if you’ve started a new job and your previous tax details are not yet available 0T W1/M1 is another emergency tax code but this means that no Personal Allowance is being applied, leading to higher tax deductions. Worldwide and Non-Resident Tax Codes NT: No tax is deducted from your income. This is usually for non-UK residents or people with special tax arrangements. K: This code is used when untaxed income (e.g., state benefits or company benefits) exceeds your Personal Allowance, meaning additional tax is due. If your tax code begins with an S then it is a Scottish code and similarly if it is a Welsh code it will begin with a C . Other Special Tax Codes There are a number of letters that may also be applied to a tax code: T: Used when HMRC needs to review your tax code (e.g., for complex tax situations or multiple income sources). Y: For people born before 6 April 1938 who qualify for a higher Personal Allowance. L: Indicates entitlement to the basic Personal Allowance. M: Given to someone receiving the Marriage Allowance from their spouse. N: Given to someone transferring part of their Personal Allowance to their spouse. How to Check and Change Your Tax Code Your tax code will appear on your payslip, P60, or P45. If you think your tax code is incorrect, you can: Check Online: Log into your personal tax account on the HMRC website . Contact HMRC: Call HMRC to request a review or correction. Seek Professional Advice: If you’re unsure, a tax advisor can help you navigate your tax situation. Why Understanding Your Tax Code Matters Getting your tax code right is essential to ensure you’re not overpaying or underpaying tax. An incorrect tax code could lead to an unexpected tax bill or a delay in receiving a refund. By understanding your tax code, you can take control of your finances and avoid unnecessary stress.
