Worth knowing
Rules that come up in this work
Director's loan accounts
The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.
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.
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
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
Questions
Self Assessment Tax Returns questions from Pentwyn Berthlwyd
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.
What does the £129 return cover?
A full SA100 with the supplementary pages for one income source, prepared, checked and filed online. Rental income, capital gains or several income sources move you to the £169 or £199 package, and we tell you which applies before we start, never on the invoice.
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.
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.
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.
Is self assessment tax returns in Pentwyn Berthlwyd really the same price as elsewhere?
Yes. The fee published on this page is what a client in Pentwyn Berthlwyd pays and what a client in any other part of Wales pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
