Hi, I'm Polina, your head accountant
I'm happy to help with whatever your business needs, whether that's handing the whole lot over to me, or just a free, no-pressure chat to make sense of something that's been confusing you. I'll always explain things in plain English, never jargon.
With over a decade in bookkeeping, payroll and accounting, I look after sole traders, contractors and growing limited companies, based in Aylesbury and working remotely with clients across the UK. You'll deal with me directly: a real person who actually knows your business, not a different voice every time you call.
Stuck on something? Grab a free consultation and I'll happily talk you through it.

Tired of an accountant who goes quiet?
I built my practice around the things people tell me they can't stand about accountants. Here's my promise to you.
You can always reach me
A real person on the end of the phone or email, not a ticket queue or a three-week wait for a meeting. I reply within one working day.
One fixed price, no surprises
You’ll know exactly what you pay each month. No hourly clock, and never a bill just for asking me a quick question.
Done right, explained simply
I get your numbers right and tell you in plain English what you owe and why, so there are no nasty surprises from HMRC.
I watch your deadlines
I keep track of every filing date and chase you in good time. You’ll never find out about a penalty when it’s already too late.
Advice all year, not just a bill
I look for ways to save you money and keep you organised throughout the year, not a once-a-year set of accounts and silence in between.
Never locked in
No tie-ins and no exit fees. If you ever want to leave, I’ll hand everything over cleanly. I’d rather earn your business every month.
Making Tax Digital for Income Tax · New from 2026
Not sure what it means for you, or how to prepare?
From 2026, many sole traders and landlords will need to keep digital records and send HMRC an update every few months, instead of one tax return a year. It sounds like a lot, but you don’t have to work it out on your own. I’ll tell you whether it applies to you, get you set up the easy way, and take care of the updates for you.

Always know exactly where your business stands
Running a small company, you’ve got enough to think about. My clients rely on me to keep the numbers clear and current, so at any point you can answer the questions that actually matter, and trust that everything is filed and paid on time.
No guesswork, no year-end shocks, just a clear picture of your business whenever you need it.

What Polina's clients say
Feedback from small business owners and sole traders Polina has helped
I’d been procrastinating for the longest time about getting my first tax return in. Polina swooped in and we got it done in one day. I’m a small business owner and she taught me how to do it myself, with fab advice for next year’s returns too. Highly recommended!
Polina is friendly, approachable and very knowledgeable. She provided me with accurate advice, and supported me (a complete novice) through the self assessment process. Highly recommend her.
When I “fell out with” my previous accountant, Best-Assistant Accounting was there to help with minimal notice. Simple, easy to work with and provides great advice, especially when working with HMRC. Highly recommended.
