Local facts
About Lavister
Lavister is in Wales, Wales. Welsh taxpayers pay Welsh rates of income tax, set by the Senedd and currently matching the English bands, collected under a C-prefixed tax code. National Insurance, VAT and Corporation Tax are UK-wide. Property purchases in Wales pay Land Transaction Tax to the Welsh Revenue Authority rather than Stamp Duty, with its own bands and rates.

Worth knowing
Rules that come up in this work
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
Closing a company
A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.
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.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Questions
Self Assessment Tax Returns questions from Lavister
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.
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.
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.
Can you deal with HMRC on my behalf?
Once you authorise us as your agent we can speak to HMRC about your return, see your account and respond to letters about the return we filed. The authorisation is free, done through your Government Gateway or a code HMRC posts to you, and takes a few days to activate.
Do I pay before or after filing?
The fee is invoiced when you approve the draft, before we file. Nothing is submitted to HMRC until it is paid and you have confirmed every figure, and you receive HMRC's submission receipt within minutes of filing.
How do payments on account work?
If your bill is over £1,000 and less than 80% of your tax is collected at source, HMRC asks for two advance payments towards next year, due 31 January and 31 July, each half of this year's bill. We calculate both and show you how to reduce them if your income is falling.
Which deadlines matter most for self assessment tax returns?
The next four dates that apply to self assessment tax returns are shown at the top of this page, calculated from today. For Lavister clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
