How Our Self Assessment Accountants Can Help
We support you through every stage of Self Assessment, from registration and tax calculations to filing and HMRC correspondence.
Self Assessment Registration and UTR Support
If this is your first return, we can help you confirm whether you need to register for Self Assessment. We can also support you with obtaining or locating your Unique Taxpayer Reference (UTR).
Income and Expense Review
We review the income and expenses that need to appear on your tax return, including self-employment income, employment records, rental income, dividends, bank interest, pensions and asset disposals. We also check the supporting records, such as receipts, transaction documents, P60s and details of taxable benefits.
Allowable Expenses and Tax Reliefs
If you are a sole trader, allowable business expenses can reduce your taxable profit. We review costs such as office expenses, business travel, staff costs, finance costs, premises, marketing and qualifying training. We also check how the £1,000 trading allowance affects your return and consider relevant tax reliefs, including qualifying pension contribution relief.
Tax Liability and Payments on Account
Your Self Assessment tax accountant calculates your tax liability and explains how HMRC calculates it. If payments on account apply, we confirm how much you need to pay and when each payment is due, normally 31 January and 31 July.
Tax Return Preparation and HMRC Filing
Once we have reviewed your records and completed the tax calculation, we prepare your tax return and any required supplementary information. We check the figures and show you the income, claims, tax due and upcoming payment obligations. You can then review and approve the return before we submit it to HMRC.
Late Returns, Amendments and HMRC Correspondence
Missed a filing deadline or found an error in a submitted return? We'll help you deal with it promptly and explain any penalties, interest or further action required. Most returns can be amended within 12 months of the usual filing deadline. If that period has passed, we can help you contact HMRC and respond to correspondence relating to your return.

I've been working with Rita since the beginning of 2024 and she has really changed the way I operate as a former freelancer, and now small business owner. Rita and her team were able to scale their efforts in step with me as I've moved from freelancer, to sole trader, to Ltd company owner, always providing great advice, guidance and the right amount of pestering. As she has expanded her team, the level of quality has not decreased in any way, and they are a pleasure to work with. The one time an error was made in my accounting software, Rita both fixed the issue incredibly quickly, and refunded me that months' payment - what more can you ask for! I don't write many reviews, but Rita and her team do truly deserve this glowing endorsement of their services.
