Ten in-depth guides for small business.
Long-form guides on the topics that move the tax bill. Grounded in 2026 reality: MTD ITSA April 2026, the new corporation tax bands, the £500 dividend allowance, the £2.5m IHT BPR cap, and Harrow-local grants. Written by tax specialists, not content marketers.
MTD for Owner-Managed SMEs
Owner-managed SMEs straddle three MTD regimes: ITSA for any pre-incorporation or side-income period, MTD VAT for registered businesses, and the in-development MTD for Corporation Tax. The compliance design has to cover whichever wrappers the founder uses (sole trader, partnership, Ltd) and the transition between them. Most owner-managers face MTD VAT first, then ITSA on residual personal income, then CT MTD when it lands.
Xero Setup for New Ltd
A new owner-managed Ltd company has a 90-day window to set up its accounting properly before the first quarter close. Get the chart of accounts right, structure the director loan account, configure dividend handling, link payroll, and onboard the right add-ons. Skip this and the cleanup at year 1 takes 20+ hours and obscures the corporation-tax position.
Tax Efficiency & Expenses
For UK small businesses, allowable expenses and capital allowance planning is the largest single lever on tax position. The wholly-and-exclusively rule, the £1m AIA, the £150 staff party allowance, electric car treatment, R&D credits, and full expensing for limited companies are the core mechanics.
Payroll & Director Pay
For UK SMEs, the payroll and director remuneration calculation has tightened in 2026. The dividend allowance fell to £500, the National Living Wage rose to £12.21/hour, and auto-enrolment compliance is firm. Director salary/dividend split, P11D compliance, and Relevant Life Policies are the planning levers.
Corporation Tax 2026
For UK limited companies, corporation tax in 2026 is two-rate: 19% on profits up to £50k, 25% above £250k, with marginal relief in between. Director Loan Account Section 455 charges, FRS 105 micro-entity reporting, and loss carry-forward/back are the planning levers.
Business Structure
For UK SMEs, business structure choice drives tax position, liability exposure, and growth optionality. Sole trader, partnership, LLP, limited company each suit different stages. Incorporation Relief defers CGT on transfer; statutory directorship duties are non-trivial; funding routes vary by structure.
Voluntary VAT for B2B SMEs
For a B2B UK SME below the £90k threshold, voluntary VAT registration is often the right call. The input-VAT recovery on setup costs and SaaS subscriptions is material, B2B customers reclaim the VAT you charge them, and the early registration date signals scale to enterprise procurement teams. This guide is about that specific decision, not the mechanics of registration itself.
Harrow Business Support
For Harrow SMEs, local financial support is a layer beyond national grants. The Harrow Business Growth Programme, rates relief on retail/hospitality, Start Up Loans, high-street regeneration funding and workplace charging grants combine into £5,000-£25,000 of available support per business.
SME Working-Capital Facilities
A UK SME with growing receivables faces a specific working-capital decision: overdraft, invoice finance (discounting or factoring), term loan, or asset finance. Each fits a different cash gap and prices differently. The personal-guarantee question matters as much as the headline rate. This guide is about that decision, not generic cash-flow forecasting.
Exit Planning & CGT
For UK SME owners, exit planning works on a 5-10 year horizon. BADR delivers 10% on lifetime gains up to £1m. The 2024 IHT BPR reform capped business relief at £2.5m. EOTs offer succession with capital tax efficiency. EMI options retain key staff pre-exit. The 2026 CGT changes touched the framework but did not break it.
