CIS rebates, self-assessment, bookkeeping and full accounting services — tailored specifically for construction companies, subcontractors and sole traders across Sheffield and South Yorkshire.
Running a construction business comes with unique financial challenges — CIS compliance, subcontractor payments, VAT on materials, and fluctuating cash flow. We understand the industry inside out and provide accounting services that keep you compliant and profitable.

If you work as a subcontractor in the construction industry, your contractor deducts CIS tax from your payments at 20% (or 30% if you're not registered). At the end of the tax year, you may be entitled to a refund — and many subcontractors are owed more than they realise.

Free, no-obligation assessment. We'll tell you exactly what you're owed.
Tell us about your business and we'll recommend the right package for you.

Managing Director
With over two decades of professional practice behind her, Anna Buggey brings a level of expertise and authority that few in the industry can match. She has been practising since 2004 and running her own businesses ever since, giving her an intimate understanding of what it takes to build, sustain and grow a successful enterprise — from navigating HMRC compliance to making the strategic decisions that shape a company's future.
Her command of the construction industry is unrivalled — CIS compliance, contractor accounting, subcontractor rebates and complex project structures are her daily discipline. Yet her reach extends far beyond the building site. Anna has steered charities through governance challenges, advised tourism and hospitality ventures at board level, championed renewable energy projects, and guided ambitious entrepreneurs through high-stakes investments. She negotiates directly with tax authorities on an international level, securing the most favourable conditions for her clients with the precision and tenacity of a seasoned professional.
As Managing Director, Anna leads a small but mighty team with the same conviction that has defined her career: that rigorous expertise and genuine care are not mutually exclusive. Under her leadership, every client — from a sole trader filing their first return to a multi-site contractor managing complex CIS obligations — receives the same meticulous attention, strategic insight and unwavering commitment to achieving the best possible outcome.
Tax by Sterling was founded in August 2019 by Andrew Buggey, whose engineering background and sharp commercial instinct saw an opportunity to do things differently. With deep roots in sales and business development, Andrew built the firm on a principle he had carried through every venture: deliver exceptional results and the reputation will follow. Together with Anna as Managing Director, they have created something rare — a small, family-run accountancy practice that combines the rigour and professionalism of a top-tier firm with the warmth and accessibility of a trusted neighbour.
Based at Sterling Enterprise Centre in Sheffield, our small but mighty team looks after the local construction companies, sole traders and startups that are the backbone of our community. We know that behind every balance sheet is a family, a livelihood and a dream worth protecting. That responsibility drives everything we do — from the precision of our tax calculations to the care we take in understanding each client's unique circumstances. We celebrate your wins, we stand beside you through the tough times, and we never lose sight of the people behind the numbers.
We hold ourselves to the highest professional standards — CPAA Certified, Xero Certified Advisors and recognised FreeAgent Tax Practitioners. But what we are most proud of is the trust our clients place in us, the community we serve, and the lasting relationships we have built along the way. That is the Tax by Sterling difference — and it always will be.
