Your 2026 Tax & Finance Checklist
What Needs Your Attention in 2026

Key changes, deadlines and actions every UK business owner, sole trader and landlord should be aware of this year. Click any item to find out more.

If you are a sole trader or landlord with qualifying income over £50,000 from self-employment and/or property, you are required to keep digital records and send quarterly updates using MTD-compatible software from April 2026. You still submit an annual tax return through compatible software. No penalty points apply for late quarterly updates in 2026/27, but the updates are still required. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028.
Check If You’re Affected →
The online Self Assessment deadline for the 2025/26 tax year is 31 January 2027. Late filing can trigger an automatic £100 penalty, with further charges for longer delays. Britvex can help organize the relevant records, prepare the return and agree the engagement fee before work starts.
Self Assessment Services →
Allowable expenses and reliefs depend on the facts and the relevant tax rules. Potential areas may include home-working costs, mileage, equipment, software, training, insurance, professional fees, R&D tax relief, EIS/SEIS, pensions and owner-remuneration planning. Britvex can review what applies and document the position before claims are made.
Explore Tax Planning →
Every UK limited company must file a Confirmation Statement (CS01) at least annually. Private-company annual accounts are normally due within 9 months of the accounting reference date, subject to the rules for first accounts and any applicable changes. Director and PSC changes can carry short statutory notification deadlines, including 14-day requirements for key changes. Britvex can track the agreed Companies House filing calendar and prepare the relevant submissions.
Company Compliance →
Landlords whose qualifying income from property and self-employment is over £50,000 are within the first mandatory MTD for Income Tax phase from April 2026, subject to the detailed rules and exemptions. Section 24 finance-cost restrictions may affect individual landlords, and taxable gains on UK residential property can require reporting and payment within 60 days of completion. Incorporation and ownership changes should be reviewed before action is taken.
Landlord Tax Services →
From 6 April 2025, Employer National Insurance increased from 13.8% to 15% and the secondary threshold fell to £5,000. The change can increase employer payroll costs, although Employment Allowance and other circumstances may affect the outcome. Britvex can review payroll setup, employer obligations and relevant reliefs as part of an agreed engagement.
Payroll & PAYE Services →
UK company owners and directors, including overseas founders, need to consider current Companies House identity-verification requirements. Cross-border businesses may also need to consider permanent establishment, treaty, transfer-pricing and UK tax-residence issues. Britvex supports international clients with UK company, accounting, tax and compliance requirements.
International Tax →
