We're a specialist team obsessed with one thing — getting UK workers every pound HMRC owes them.
Maximum Rebate was founded on a simple frustration: too many UK workers — particularly in construction, trades and transport — are quietly overpaying HMRC every single year, often by thousands of pounds. The system is built for accountants and professionals who already understand it. For everyone else, it's a maze.
We exist to fix that. Our team includes former HMRC-trained specialists, tax accountants and CIS experts who spend every working day inside the rebate system. We know exactly which expenses are reclaimable, which claims HMRC will accept first time, and how to navigate around the most common bottlenecks.
We don't do company accounts, payroll, or VAT. Our entire focus is tax recovery — which means our process, our checks, and our HMRC relationships are all tuned for one outcome: getting your refund quickly.
If we can't recover any tax for you, you owe us nothing. No setup fees, no admin charges, no hidden costs. We only get paid when you do.
Many of our clients see refunds in under 7 days from HMRC processing. We get claims right first time, so they don't sit in HMRC review queues for months.
You'll always speak to a named specialist — never a faceless call centre. We'll keep you updated at every stage, and we're equally happy chatting by phone, email or WhatsApp.
It takes about 60 seconds to check eligibility. No commitment, no obligation.
Check My RefundHonesty. If you're not owed anything, we'll tell you. If we think a claim is borderline, we'll explain the risk before submitting.
Clarity. Tax doesn't have to be complicated. We explain things in plain English, document everything, and never hide behind jargon.
Persistence. HMRC delays happen. When they do, we keep chasing — politely but firmly — until your refund is in your account.
Tell us about your work and we'll instantly assess whether you're owed a refund.
We guide you through exactly what's needed and handle the rest.
