Self Assessment Tax Returns
A Self Assessment tax return reports income that has not been fully taxed at source, such as self employment profits, partnership profits, untaxed dividends or capital gains. Sterling Crest Accountants prepares returns from your records, calculates the tax and National Insurance due, explains any payments on account, and files with HMRC once you approve the draft.
Sterling Crest Accountants provides this service to clients throughout the United Kingdom. Consultations are arranged in advance by telephone or online meeting. Our registered office is in Leeds, West Yorkshire.
About Self Assessment tax returns
We gather information for self employment, partnership profit shares, employment, dividends, interest, pensions and other income you disclose. Capital gains sections are completed when you provide disposal details within scope.
Not everyone needs to file. You may need a return if, for example, you were self employed with income over £1,000, were a partner in a business partnership, had untaxed income or capital gains to report, or received a notice to file from HMRC. Being a company director does not by itself always mean a return is required; it depends on your income and whether HMRC has asked you to file.
Calculations include Income Tax, Class 4 National Insurance and any voluntary Class 2 contributions where relevant, student loan repayments and payments on account for the following year. We explain the balancing payment and due dates in plain English.
Returns are submitted electronically through HMRC compatible software once you sign off the draft. Routine HMRC acknowledgement letters and simple queries can be handled when within agreed scope.
Residence, remittance basis, domicile issues and formal enquiry representation are not automatically included. We flag when facts look complex and need wider advice.

Frequently asked questions
Only if you disclose full details. Foreign tax credit relief and residence questions may need wider scope.
Online returns must be filed by 31 January after the end of the tax year, which is also the date to pay any tax owed. Paper returns are due by 31 October.
Depending on your income: P60 and P11D forms, self employment or partnership figures, dividend and interest statements, pension income, details of any capital gains, Gift Aid and pension contributions, and your UTR. We send a checklist based on your sources of income.
It depends on your income. Common reasons include self employment income over £1,000, a share of partnership profits, untaxed income or gains, or a notice to file from HMRC. Employees taxed fully through PAYE often do not need to file. We can confirm from your circumstances.
Not automatically. Being a company director is not, by itself, one of the reasons GOV.UK lists for having to send a return. Directors usually need one where they have untaxed income, such as dividends above the dividend allowance, or where HMRC has sent a notice to file.
Yes, through our HMRC registrations service. If you need to file for the first time, HMRC should be told by 5 October after the end of the tax year.
Advance payments towards your next tax bill, usually required when your last Self Assessment bill was more than £1,000 and less than 80% of your tax was collected at source. They are due by 31 January and 31 July.
Enquiry support is a separate service. We can discuss scope if a notice arrives.
We e file approved returns. Paper filing is exceptional and usually discouraged by HMRC.
You pay HMRC directly. We tell you amounts and dates after filing.
