Section 455 Tax Calculator

If your director's loan account is overdrawn at your company's year-end—and it isn't repaid within nine months—your company faces a 33.75% tax charge under Section 455 CTA 2010. That's not a penalty. It's a real tax bill that HMRC will collect. And most directors don't realise it's coming until their accountant tells them—often too late to do anything about it. The Section 455 Tax Calculator shows you exactly where you stand. In real time. It displays your current DLA balance, the nine-month repayment deadline, the projected Section 455 charge if the loan isn't cleared, and what-if scenarios for partial repayments. No surprises. No unexpected tax bills. Just clear, actionable visibility.

Challenges We Solve

Transforming complex problems into seamless automated workflows.

Directors don't know they owe Section 455 tax until it's too late

Section 455 is one of the most misunderstood tax charges in UK company law. Many directors only discover the 33.75% charge when their accountant prepares the Corporation Tax return—months after the repayment deadline has passed.

  • Real-time DLA balance tracking against the Section 455 threshold
  • Clear countdown to the nine-month repayment deadline
  • Projected tax charge displayed in pounds—not percentages
  • Push notification alerts when thresholds are approaching

Calculating the charge manually is confusing

The Section 455 charge applies at 33.75% on the outstanding balance at the nine-month mark. But what if you make partial repayments? What if you declare a dividend to offset it? Modelling scenarios manually in a spreadsheet is complex and error-prone.

  • Automatic calculation at the current 33.75% rate
  • What-if modelling for partial repayments and dividends
  • Scenario comparison showing tax saved per option
  • Multi-year tracking if the loan spans accounting periods

No proactive warnings from your accounting software

QuickBooks and Xero don't understand Section 455. They track the DLA balance but don't warn you about the tax implications. You need a system that connects the dots between your loan balance, your year-end date, and the nine-month deadline.

  • Purpose-built for UK director's loan tax compliance
  • Integrates with your DLA data and company year-end date
  • Proactive alerts—not just passive balance reporting
  • Recommendations for repayment strategies with tax impact

Key Features

Powerful tools built specifically to accelerate your growth.

Real-time Section 455 exposure dashboard

What this means for you: You always know exactly how much Section 455 tax you'd owe if you did nothing.

A dedicated dashboard shows your current DLA balance, your company's year-end date, the nine-month repayment deadline, and the projected Section 455 charge in real pounds. The display updates as transactions are recorded against your DLA.

  • Live DLA balance with Section 455 impact
  • Countdown timer to the nine-month repayment deadline
  • Tax charge shown in pounds, not just percentages
  • Traffic-light status: green, amber, red

What-if scenario modelling

What this means for you: Make informed decisions about how to clear your DLA—backed by real numbers, not guesswork.

Model different repayment strategies and see the tax impact instantly. 'What if I repay £10,000 this month?' 'What if I declare a £5,000 dividend instead?' Each scenario shows the resulting DLA balance, the revised Section 455 charge, and the tax saved.

  • Side-by-side scenario comparison
  • Dividend vs. repayment vs. salary trade-off analysis
  • Tax saved displayed per scenario in pounds
  • Shareable scenario reports for accountant review

Automatic repayment tracking and reclaim

What this means for you: You never overpay Section 455 tax—and you reclaim it as soon as you're entitled.

When you repay the loan (in part or in full), the calculator automatically recalculates the Section 455 exposure. Once the loan is fully repaid, the system flags that you can reclaim the Section 455 tax paid—and generates the reclaim paperwork.

  • Automatic recalculation on every repayment
  • Section 455 reclaim eligibility flagged automatically
  • Reclaim paperwork generated for submission to HMRC
  • Historical tracking of all Section 455 charges and reclaims

Prevent thousands in avoidable tax charges

The Section 455 Tax Calculator turns a complex, hidden tax risk into a visible, manageable number on your dashboard.

  • Real-time exposure prevents surprise year-end tax bills
  • Scenario modelling finds the most tax-efficient repayment path
  • Automatic reclaim generation recovers overpaid tax
  • Proactive alerts ensure you act before the deadline passes

Real-World Scenarios

Avoiding a £6,750 tax charge

"Your company year-end is 31 March and your DLA shows a £20,000 overdrawn balance. The Section 455 calculator displays: 'Repayment deadline: 31 December. Projected charge: £6,750.' You decide to repay £12,000 now and declare an £8,000 dividend. The scenario modeller confirms: Section 455 charge reduced to £0."

Outcome: You save £6,750 in tax by acting three months before the deadline—armed with clear data.

Reclaiming Section 455 tax after loan repayment

"Last year you couldn't repay in time and paid £3,375 in Section 455 tax. This year you've repaid the full loan balance. The calculator flags: 'Eligible for Section 455 reclaim — £3,375.' It generates the reclaim form and you submit it via the HMRC filing module."

Outcome: £3,375 reclaimed from HMRC. The system tracked the eligibility automatically.

"Last year we got hit with an unexpected £8,400 Section 455 charge. This year, the calculator showed us the exposure three months before the deadline. We repaid the balance and saved the entire charge. It paid for our ByVeya subscription ten times over."

Got Questions?

Everything you need to know about the product and billing.

What is the current Section 455 tax rate?

The Section 455 tax charge is 33.75% of the outstanding director's loan balance at the nine-month mark after the company's year-end. The calculator always uses the current rate and will update automatically if HMRC changes it.

Can I avoid Section 455 by declaring a dividend?

Yes—if the dividend is declared and paid before the nine-month deadline, it reduces the DLA balance and therefore the Section 455 exposure. The scenario modeller lets you see the exact tax impact of this approach.

Does the calculator work for multiple directors?

Yes. Each director's loan account is tracked separately. If your company has multiple directors with overdrawn DLAs, the calculator shows the Section 455 exposure per director and for the company as a whole.
