Tax

Your tax, in safe hands

Tax can feel stressful, especially when a letter from HMRC arrives or a deadline is getting close. Our job is to take that weight off you. We prepare and file your returns, from Self Assessment and Corporation Tax to VAT, Capital Gains Tax, crypto and ATED, and make sure you pay what the rules require and not a penny more.

Your return is prepared by an experienced accountant who looks at your whole situation, not just the figures on the form.

We work with individuals, landlords, company directors, sole traders and charities. We keep track of your deadlines for you and explain, in plain English, what you owe and why.

If your situation is more complex, such as R&D tax relief, cryptoassets, an HMRC enquiry or property held through a company, we give you clear written advice, so you know exactly where you stand before you decide.

Common tax questions

Do I need to file a Self Assessment tax return?

You usually need to file if you were self-employed and earned more than £1,000, were a partner in a business partnership, had Capital Gains Tax to pay, or had to pay the High Income Child Benefit Charge. You may also need to file if you have untaxed income, such as rent, dividends, savings interest or foreign income. If you are not sure, ask us and we will check for you.

When are the tax deadlines?

For Self Assessment, you must tell HMRC by 5 October if you need to file for the first time. Paper returns are due by 31 October. Online returns, and payment of the tax you owe, are due by 31 January after the end of the tax year. If you make payments on account, the second payment is due by 31 July. Companies have different deadlines: Corporation Tax is normally payable 9 months and 1 day after the end of the accounting period.

What happens if I file or pay late?

HMRC charges an initial £100 penalty if your Self Assessment return is late. After 3 months there are daily penalties of £10 a day, up to a maximum of £900, with further penalties after 6 and 12 months. If you pay late, HMRC charges interest and penalties of 5% of the unpaid tax at 30 days, 6 months and 12 months. If you have already missed a deadline, contact us as soon as you can so we can get your return filed.

What do you need from me to prepare my return?

It depends on your situation, but usually we need your Unique Taxpayer Reference (UTR), details of your income for the year (such as a P60 or P45, invoices or sales records, rental income, dividends and interest), records of your business expenses and any letters you have had from HMRC. We will tell you exactly what we need for your case.

How much does a tax return cost?

The fee depends on how complex your affairs are. You can see our starting prices in the price list. We agree the fee with you before any work starts.
