Understand Your Corporation Tax Rates for 2026
The way you are taxed on your company profits depends on how much you earn. For the 2026 financial year, the tiered system remains the primary way HMRC calculates your liability. Understanding where you fall within these bands will help you forecast your cash flow more accurately.
- The Small Profits Rate (19%): If your company’s augmented profits are £50,000 or less, you will typically pay the 19% rate. This is designed to support smaller businesses and start-ups as they find their footing.
- The Main Rate (25%): If your profits exceed £250,000, your company will be subject to the 25% main rate.
- Marginal Relief: If your profits fall between £50,000 and £250,000, you don’t jump straight to 25% on everything. Instead, you pay a gradually increasing effective rate. This ensures there isn’t a “tax cliff” as your business scales.
Keep in mind: If you have associated companies (other companies under the same control), these thresholds are divided between them. We recommend keeping a close eye on your group structure to avoid unexpected tax hikes.
Monitor the £90,000 VAT Registration Threshold
VAT compliance is often the most complex area for digital businesses and ecommerce sellers. As of 2026, the VAT registration threshold remains at £90,000 of taxable turnover in any rolling 12-month period.
Register early to avoid retrospective fines. If you expect your turnover to cross this limit within the next 30 days, or if you have already crossed it in the last 12 months, you must register. Once registered, you are required to charge VAT on your sales and, crucially, you can reclaim VAT on your business-related purchases.
Doing this properly will save you significant amounts of money on stock and digital services, but it does require strict record-keeping. Under the current Making Tax Digital (MTD) rules, all VAT-registered businesses must use compatible software to file their returns. This is where a structured tax accounting service becomes essential to ensure every transaction is captured accurately.
Simplify Your Payroll and Director’s Salary
As a director of a UK Limited Company, you are also an employee. This means you need to set up a Pay As You Earn (PAYE) scheme with HMRC. Even if you are the only person in the company, maintaining a payroll system is essential for taking a salary and making National Insurance contributions.
Most directors choose a “low salary, high dividend” strategy to remain tax-efficient. However, even a small salary requires regular Real-Time Information (RTI) submissions to HMRC. Submit these on time to avoid automatic late-filing penalties. By managing this correctly, you ensure you are building up your qualifying years for the State Pension while keeping your company’s tax bill as low as possible.
Prepare for Making Tax Digital (MTD) Updates
2026 marks a major turning point for HMRC’s digital roadmap. While Limited Companies already use digital systems for VAT and Corporation Tax filings, a new phase of Making Tax Digital for Income Tax begins on April 6, 2026.
If you are a business owner who also receives significant income from sole trader activities or other sources outside your Limited Company (totalling over £50,000), you will need to comply with new quarterly reporting requirements for your personal tax return. Don’t worry, this doesn’t change how your Limited Company files its accounts, but it does mean your personal tax affairs will require more frequent attention.
Maintain Accurate Records with a Structured System
The secret to stress-free tax compliance is ongoing bookkeeping. Gone are the days of handing a box of receipts to an accountant once a year. To succeed in 2026, you need a tech-driven approach that captures data daily.
It is essential to use cloud-based software to track your income and expenses. This allows you to:
- See your real-time tax liability so you aren’t surprised by a bill at year-end.
- Reconcile bank statements instantly to ensure no expenses are missed.
- Store digital copies of receipts, fulfilling HMRC’s requirements for digital record-keeping.

Frequently Asked Questions
What is the Corporation Tax deadline for UK Limited Companies?
Your Corporation Tax payment is usually due 9 months and 1 day after the end of your accounting period. Your Company Tax Return (CT600) is due 12 months after the end of your accounting period.
Do I need to register for VAT if I sell to customers outside the UK?
This depends on where your customers are located and where your goods are held. For many international sellers, VAT registration is required even before the £90,000 threshold is met. We specialise in cross-border VAT and can help you determine your exact requirements.
Can I file my own accounts to HMRC?
Yes, you can, but it is highly risky for growing businesses. HMRC’s rules for iXBRL tagging and digital submissions are strict. Errors can lead to audits and heavy fines. Using a structured compliance service ensures your accounts are filed correctly every time.
What happens if I miss a tax deadline?
HMRC issues automatic penalties for late filings and late payments. These start small but can escalate quickly to hundreds or thousands of pounds. Staying ahead of deadlines is the easiest way to protect your company’s profits.
