Everything your books and tax need
Tap through what we offer. Choose the services you want and leave the rest to us — clear scope, clear pricing.
HMRC on your side of the table
Had a letter, check or enquiry from HMRC?
Don't face it alone. We handle your tax affairs directly with HMRC — compliance checks, enquiries, investigations and disclosures — and deal with the correspondence so you don't have to.
How it works
Switching to us is straightforward
Four simple steps and we take it from there. Most of it happens online, in your own time.
Free consultation
A quick chat about your business and what you need. No obligation, no jargon.
Onboarding & ID
A short form, identity checks, and we request handover from any previous accountant.
We take over
We set up your software, agree a fixed fee, and pick up your books and filings.
Year-round support
We keep everything current and on time, and you can reach us whenever you need.

Why ZSL
A practice that stays close to your business
Here all year
We keep your records current month to month — no scramble, and no surprises, when a deadline lands.

Simple plans and fixed fees agreed up front. You always know what you pay and what you get.
Cloud-first
We work in Xero and QuickBooks, so your numbers are live, accurate and with you wherever you are.
A real person
You deal with someone who knows your business by name — not a call centre or a new face each time.
About us
London accountants who keep it human
ZSL Accountants and Tax Advisors is a London-based practice founded by Shehryar Khan and Laiba Qazi. Between us we bring an MSc in Accounting & Finance, an ACCA and AAT background, and up to eight years' hands-on experience in UK practice — from bookkeeping, VAT and payroll to management accounts, forecasting and dealing with HMRC.
We set the firm up to do things a little differently: modern cloud tools, fees you can understand, and a genuine relationship with every client. Whether you're going self-employed, running a growing company, or facing a question from HMRC, we make the numbers the easy part.
The team
Questions
Good to know
Yes. We'll talk through your situation with no obligation and no charge. You only pay once you've agreed a fixed quote and decided to go ahead.
Not at all. With your permission we contact your current accountant, request the handover, and take it from there. You mostly just need to say the word.
Yes. We can act for you with HMRC and handle compliance checks, enquiries, investigations and disclosures — dealing with the correspondence and the negotiation so you don't have to.
Mainly Xero and QuickBooks. If you're already on one we'll work in it; if not, we'll get you set up on the right one as part of onboarding.
It depends on your size and what you need. Use the estimator above for a guide, then we'll give you a clear fixed fee before any work starts — no hidden extras.
Yes. We work mostly online, so we look after clients across the UK just as easily as those nearby.
