UK company, individual and partnership tax returns

First distinguish between companies, sole traders, partnerships and overseas establishments, then assess tax residence, UK business and registration for each tax. Companies House registration, corporation tax, VAT, PAYE and personal returns are not a single automatically combined approval process. Neither non-resident nor non-profit status automatically confers tax exemption.[20] [21] [22] [28]

• Corporation tax: ordinary UK tax-resident companies pay tax on UK and overseas profits, while the UK branch of a non-resident parent company is treated by reference to its UK profits. Corporation tax is generally due 9 months and 1 day after the accounting period ends, and CT600 is due within 12 months; large companies have a separate instalment regime. A corporation tax accounting period cannot exceed 12 months. A longer first set of statutory accounts may therefore require two corporation tax returns. Making a loss does not mean that an issued notice to file can be ignored.[20] [22] [23]

• Corporation tax generally applies at the 19% small profits rate or the 25% main rate, with basic profit thresholds of GBP50,000 and GBP250,000. Short accounting periods and associated companies reduce the thresholds. Non-UK tax-resident companies and close investment holding companies are not automatically entitled to the small profits rate and marginal relief arrangements; not all holding companies can be assessed at 19%.[20] [21]

Sole traders and partnerships: use Self Assessment rather than each filing CT600. For partnerships, the nominated partner first reports the allocations, and members then pay tax according to their respective status. New filers for the 2025/26 tax year generally notify HMRC by 2026-10-05; paper returns are due 2026-10-31, and online returns and usually tax payments are due 2027-01-31. Qualifying payments on account have a separate deadline of month 7, day 31. Special cases, including those involving corporate partners, must follow the specific deadlines.[19] [48]

• The compulsory registration test for VAT generally concerns taxable turnover exceeding GBP90,000 over a rolling 12-month period, or expected to exceed that amount in the next 30 days alone. Businesses established overseas making taxable supplies in the UK may not benefit from this threshold. Zero-rated supplies also count towards taxable turnover; selling only exempt or out-of-scope items differs from making zero-rated supplies, and estimated annual sales cannot simply replace the statutory tests.[28] [29]

• When employing staff or paying directors, first assess PAYE registration and National Insurance obligations based on the actual payment conditions. For 2026/27, the standard employer Class 1 rate is 15%, the annual Secondary Threshold is GBP5,000 and the Lower Earnings Limit is GBP6,708. Employment Allowance is up to GBP10,500, but cannot be claimed where the sole director is the only employee liable for employer Class 1 NI.[31] [32]

• VAT and payroll: VAT returns are generally quarterly, with filing and payment usually due one month and seven days after the end of the accounting period; returns are required even where nothing is payable. Businesses registered for VAT must keep records under the applicable digital rules and file through compatible software, except where an approved exemption or similar exception applies. Payroll RTI is generally submitted on or before payday. The 2026/27 budget must use 15% standard employer NI and the conditional Employment Allowance of GBP10,500, rather than the old values of 13.8% and GBP5,000.[30] [31] [32] [53] [56]

MTD Income Tax: eligible sole traders or landlords are tested on total gross self-employment and property income, not merely net profit. Those whose 2024/25 income exceeds GBP50,000 must start from 2026-04-06. 2025/26 income exceeding GBP30,000 corresponds to 2027-04-06, and 2026/27 income exceeding GBP20,000 corresponds to 2028-04-06. The implementation date for general partnerships remains to be announced separately; limited companies or all partnerships must not automatically be included in the 2026 cohort.[27]

• After receiving the 10-digit UTR from HMRC, configure the Corporation Tax business account according to the company's actual trading status. If UTR has not arrived after 15 working days, an enquiry may be made through the official service. Once the company starts trading, promptly confirm HMRC registration and the accounting period, and deal with VAT and PAYE according to their respective conditions. Receipt of UTR and activation of tax services should not be misrepresented as all being completed automatically within 14 days of every company's incorporation.[22] [47]

• Establish accounting records, invoices, bank reconciliations and payroll records from the first transaction, and schedule deadlines separately for Companies House, corporation tax, VAT and individual or partnership tax returns. Include registered office renewals, role-related identity verification submissions, registers of members and change reminders in the same maintenance checklist. However, appointing an agent does not relieve directors or designated members of their statutory responsibilities.[7] [11] [23] [26]

• Software and accounts reforms: the old HMRC joint online service for company accounts and Company Tax Returns closed on 2026-03-31. From 2026-04-01, commercial software is generally used to submit CT600, tax computations and accounts to HMRC, with limited exceptions for paper submissions. Companies House has not simultaneously closed all web and paper accounts filing channels; its unified software and iXBRL requirements are planned to take effect from 2028-04-01. On 2026-10-23, Companies House announced a pause in the new requirement for small and micro companies to file profit and loss accounts from 2028-04, retaining abridged and filleted accounts options. Commercial software and iXBRL filing reforms continue on the 2028-04 timetable, while web channels for filings other than accounts remain available.[33] [34] [99]

• Suitable for two or more participants arranging profits, decision-making and exit through a partnership agreement, commonly used in professional services and joint operations. LLP is a separate legal entity, but tax on a trading partnership is generally borne by members according to their profit shares; this does not justify promoting LLP or its overseas members as wholly tax-exempt.[11]

• SLP is a limited partnership registered in Scotland with separate legal personality, suitable for partnership or fund structures that genuinely require this legal characteristic. It is not a “Scotland IBFC” offshore financial licence, nor is there a uniform 3% transaction tax as claimed in the original guide on this topic. Tax treatment must still be analysed under the applicable partnership, member and UK business rules.[12] [20] [22] [54]

• Those required by home law to prepare, audit and disclose accounts generally submit them to Companies House within three months after the home-law disclosure deadline. Those outside this category generally file under the corresponding UK rules within 13 months after year-end, with special rules for the first period. The current overseas accounts processing fee is GBP50 for digital filing and GBP110 for paper filing. Changes to the UK establishment and parent company follow their 21-day rules. Separately check UK branch corporation tax and the OS DS01 notification for closing an establishment; do not apply uniform Ltd deadlines of CS01 and 9 months.[3] [16] [22]

• Dividends and loans: dividends must be supported by legally distributable profits. For UK-resident individuals, the 2026/27 dividend allowance is GBP500, with excess amounts subject to the applicable 10.75%, 35.75% or 39.35% tax band. Loans by a close company to shareholders or associated persons require a separate check under s455; the corresponding tax rate for new loans from 2026-04-06 is 35.75%. Not all director withdrawals can be categorically described as subject to a heavy 33.75% tax. For qualifying asset disposals from 2026-04-06, the BADR rate is 18%, no longer 10%.[38] [39] [40]

• Research and development and data compliance: for accounting periods beginning on or after 2024-04-01, the merged RDEC pre-tax credit rate is 20%, and the credit itself is taxable income. Loss-making research-intensive SME have a separate ERIS; 14.5% is the credit rate for surrenderable losses, not a turnover refund, and must not simply be added to Patent Box to promise an overall company tax rate of 10%. When processing personal data, assess ICO registration and exemptions separately. Current annual fees for most organisations are GBP52 or GBP78, reaching GBP3,763 for large organisations. Accounting evidence, books and decision records should be retained for their respective statutory periods; dormant accounts must not conceal actual expenditure.[24] [43] [44]

• Company registration does not constitute financial authorisation, tax-exempt status or a guarantee of opening a bank account. Ordinary companies are not subject to uniform requirements for a FCA compliance officer, MLRO or financial capital; any authorisation required for the actual business must be checked separately.[2] [36] [46]
