Our Self Assessment Service
We begin by gathering all of your income sources for the tax year — employment income, self-employment profits, rental income, dividends, capital gains, and any other taxable receipts. We review each source carefully, ensuring that allowable expenses and reliefs are correctly applied. For self-employed clients, we go through business expenditure in detail, identifying every legitimate deduction so that the taxable profit is no higher than it needs to be. For landlords, we review property costs including mortgage interest, letting agent fees, maintenance, and allowable furnishings.
Once the return is prepared, we calculate your tax liability — including any payments on account due in July — and present the figures to you clearly before filing. We highlight where you might reduce your bill in future years, whether through pension contributions, timing of income, or changes to how you structure your affairs. After filing, we set up payment reminders so you are never caught out by the 31st January or 31st July deadlines.
All HMRC correspondence is routed through us as your registered agent, so you are not left dealing with letters or online notices that can be confusing to interpret. If HMRC opens an enquiry into your return, we handle the response and represent your position throughout the process.

Frequently Asked Questions
What is the deadline for Self Assessment?
The deadline for filing your online Self Assessment tax return is 31st January following the end of the tax year (5th April). For example, for the 2024/25 tax year, the online filing deadline is 31st January 2026. Paper returns must be submitted by 31st October. Any tax owed is also due by 31st January.
Can I claim expenses on my tax return?
Yes. Self-employed individuals can claim expenses that are wholly and exclusively for business purposes — including office costs, travel, equipment, professional subscriptions, and marketing. Directors can also claim certain expenses. We review your circumstances thoroughly to ensure every eligible deduction is claimed.
What happens if I miss the filing deadline?
Missing the 31st January deadline results in an automatic £100 penalty, even if no tax is owed. Further penalties of £10 per day apply from 3 months, and additional penalties from 6 months and 12 months. We begin your return well in advance of the deadline to ensure this never happens.
Do I need to register for Self Assessment?
If you are self-employed, a company director, or have income that isn't taxed at source, you must register for Self Assessment with HMRC. The registration deadline is 5th October following the end of the relevant tax year. We can handle this registration on your behalf.
