UK Tax Guides 2026/27 — current rules, deadlines and what to do next.
Practical UK tax guidance for companies, sole traders, landlords and individuals — covering Making Tax Digital for Income Tax, Self Assessment, Corporation Tax, VAT, Capital Gains Tax and landlord tax, with direct routes into Britvex support.
Start with the taxpayer, then the event.
Company profit, self-employment income, rent, a disposal and VAT turnover create different reporting routes. The fastest way to the right answer is to identify what happened and who it happened to.
Search the question you actually have — then move directly to the relevant service.
These guide pathways are structured around the UK tax searches that most often signal an immediate compliance or advice need in 2026: MTD, Self Assessment, Corporation Tax, VAT, property and gains.
Making Tax Digital for Income Tax 2026
Understand who entered MTD from 6 April 2026, qualifying income, digital records, quarterly updates and the next rollout thresholds.
Self Assessment 2026/27
Understand who may need a return, the 31 January online filing and payment cycle, records to keep and where property or self-employment income fits.
Corporation Tax 2026
Understand the 19% small-profits rate, 25% main rate, marginal relief, payment timing and how the Company Tax Return connects to annual accounts.
Making Tax Digital is now a live compliance issue, not a future planning topic.
For the first mandatory cohort, digital record keeping and quarterly Income Tax updates are already part of the 2026/27 operating year. That makes bookkeeping quality, software readiness and deadline control more commercially important for sole traders and landlords.
For companies, the Corporation Tax rate structure remains split between the 19% small-profits rate and 25% main rate, while VAT registration remains driven by the £90,000 taxable-turnover threshold subject to detailed rules.
Question → records → calculation → return.
Useful tax content should shorten the route from a search query to the documents, calculation and filing work the taxpayer actually needs.
Who is the taxpayer?
Company, individual, landlord, sole trader or overseas owner determines the first branch of the tax route.
What created the tax issue?
Profit, income, rent, a sale, VAT turnover, payroll or another event determines which regime applies.
What records support the position?
Accounts, invoices, expenses, purchase and sale records, digital books and prior returns support the calculation.
Move from guidance to filing

Choose the guide that matches the immediate tax question.
Each route connects directly to the existing Britvex service page so visitors can move from general guidance into practical support without searching the site again.

What are the first MTD quarterly update deadlines?
For businesses using standard update periods in the first mandatory year, HMRC lists quarterly update deadlines of 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027.

The usual online filing and payment deadline is 31 January following the end of the relevant tax year, although individual circumstances and specific obligations can create other dates.
Can Britvex prepare the return as well as explain the rule?
Yes. The guide hub is designed to explain the route, while the connected Britvex service pages cover the accounting, calculation, filing and compliance work required for the actual case.
Know the rule. Then get the records, calculation and filing connected.
If your tax question already involves an approaching deadline, an HMRC notice, MTD, a VAT threshold, a company year end or rental income, move from the guide into the relevant Britvex service.
