Identify Missed Deductions & Fix Past Mistakes

One of the biggest advantages of moving to a new accountant is finally getting a clear look at where you stand. Many clients come to us after years of feeling unsure whether their accounts were done properly or whether they were missing out on tax reliefs they were entitled to. When you switch to Lanop, we start with a full review of your past returns, bookkeeping and VAT records to make sure nothing important has been overlooked.

This review is especially helpful for anyone changing tax accountants because it gives you clarity on how accurate your previous filings were. We look for missed expenses, duplicated entries, incorrect allowances, or areas where you may have overpaid. If we find issues, we explain them in simple language and advise whether corrections are needed. It’s all about giving you confidence that your finances are finally being handled the right way.

How It Works

Post-Switch Compliance Review & Systems Health Check

Switching accountants isn’t just about moving your records from one firm to another. Once the process of changing accountants is complete, the real value begins. At Lanop, we carry out a deep compliance review to make sure everything in your financial system is correct, up to date, and fully aligned with HMRC requirements. This is especially important if you’ve had concerns about missed deadlines, inaccurate filings, or gaps in communication with your previous accountant.

Our compliance review covers the essentials: VAT returns, PAYE submissions, CT600 filings, SA100 tax returns, Companies House deadlines, UTR authorisation checks, and any outstanding HMRC correspondence. We look for missing submissions, incorrect codes, duplicated entries, and historic mistakes that could affect future filings. If anything is overdue or inaccurate, we correct it and explain exactly what was found so you can move forward with confidence.

 Trustindex verifies that the original source of the review is Google. We're a small company in business for 23 years. We've been with Lanop for over a year now. From the outset they listened carefully to our somewhat complex bookkeeping needs (we sell products and services with different tax codes); they've provided a tailored solution that they execute with precision and in a timely manner. We hired them to provide combined bookkeeping, payroll and accountancy service, and they're a dream to work with on all aspects. They are careful and conscientious, and never last minute. Excellent measured responses when I ring up with questions - always so friendly, too. The price is very reasonable, not least given the high standard of service and the peace of mind we have. Top drawer.

 Trustindex verifies that the original source of the review is Google. I'm in the early stages of a startup and got in touch with Lanop, who looked to be very knowledgeable in my niche. I booked a 30-minute consultation with Muhammad, who was great and understood all the challenges i'd be facing and what direction i need to go. I was very impressed with his advice, and i came away with confidence and reassurance that this is someone i need to be working with as i scale up.

 Trustindex verifies that the original source of the review is Google. I was so lost in the woods with taxes and accounts, and on top of that, I had a limited company I was eager to get off my hands. Lanop was fabulous from start to finish and got everything taken care of. I went from being a bundle of nerves about anything financial to feeling totally at ease. I never thought I'd see the day! Everything occurred in a timely manner and I was always updated on everything that was going on, which was lovely. I was also quoted really fairly for everything as well! Above all else, Lanop gave me incredible peace of mind. If you work with them, you'll certainly be in good hands.
