Worth knowing
Rules that come up in this work
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
Corporation Tax rates and marginal relief
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
The VAT registration threshold
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
Salary versus dividends
Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
Questions
Self Assessment Tax Returns questions from Llaneurwg
I am employed and have a small side income. Do I need a return?
If the side income is under £1,000 a year the trading allowance covers it and no return is needed. Above that you must register and file. If the side income is the only reason for the return, the £129 package applies and we make sure your PAYE figures from the P60 are reconciled correctly.
Will Making Tax Digital change my return?
From April 2026 sole traders and landlords with qualifying income over £50,000 send quarterly updates to HMRC through software, with the £30,000 threshold following in April 2027. The year-end return becomes a final declaration. We set this up through our bookkeeping service when it applies to you.
What happens after you file?
You receive HMRC's submission receipt, a PDF of the return, the tax computation and a payment schedule with HMRC's bank details and your payment reference. We diarise next year's deadlines for you and send reminders before each one.
What if my return is late?
We file late returns at the £179 rescue fee, which includes drafting a reasonable-excuse appeal where the facts support one. The £100 automatic penalty is HMRC's, not ours, and we tell you honestly whether an appeal has a realistic chance before you pay for it.
I have never filed before. Do I need a UTR first?
Yes. If you have not registered we handle the registration as part of the job and HMRC posts your Unique Taxpayer Reference within about ten working days. Start early if your first deadline is close, because HMRC will not accept a return without it.
How quickly can you file once I send my records?
Most straightforward returns are drafted within five working days of receiving complete records and filed the day you approve. In January we prioritise by deadline risk and tell you your slot when you book, so late bookers are not left guessing.
