Worth knowing
Rules that come up in this work
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.
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.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
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.
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.
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.
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Questions
Capital Gains Tax questions from Sipson
I am not UK resident but sold a UK property. Do I need to report?
Yes. Non-residents must report all UK land and property disposals within 60 days, whether or not tax is due, and residential property gains are generally rebased to April 2015 values. The rules differ from those for residents and the penalties for not reporting are the same. We handle non-resident returns regularly.
I am an executor. Do I report gains for the estate?
Yes. During the administration period the estate is a separate taxpayer with its own annual exemption and pays CGT at 24% on gains above probate value. Residential property sales by the estate are subject to the 60-day rule. We prepare the estate computations and the trust and estate return pages.
Do transfers between spouses trigger tax?
No. Transfers between spouses or civil partners living together are at no gain and no loss; the recipient takes over the original cost. This allows both annual exemptions and both basic rate bands to be used on a later sale, which is a common and legitimate way to reduce the tax on a jointly planned disposal.
What if I sell shares from an employee share scheme?
It depends on the scheme. Shares from a SAYE or SIP scheme have specific cost rules and sometimes income tax has already been paid on part of the value. Options exercised and sold on the same day may have no gain at all. We need the scheme documents and the exercise and sale figures, and we apply the correct treatment for each.
What is business asset disposal relief?
Formerly entrepreneurs' relief: a reduced rate on gains from selling all or part of a trading business, or shares in a trading company where you held at least 5% and were an officer or employee for two years. The lifetime limit is £1 million. The rate rose to 14% in April 2025 and to 18% from April 2026. Our £299 service prepares and supports the claim.
I gave a property to my child. Is there tax?
Yes. Gifts to anyone other than your spouse or civil partner are disposals at market value, and the gain is taxable even though no money changed hands. The 60-day return applies to residential property. Gift relief can defer gains on business assets, but not on investment property. We value, compute and report the gift.
Do you have an office in Sipson?
No. IGI Accounting is an online-only firm. We serve Sipson and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for capital gains tax is the same in Sipson as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is capital gains tax in Sipson really the same price as elsewhere?
Yes. The fee published on this page is what a client in Sipson pays and what a client in any other part of England 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.
