Frequently asked
It depends on your business — a sole trader's return is very different to a limited company with VAT and payroll, so we don't do one-size-fits-all pricing. A quick call is all it takes: tell us a couple of details and we'll give you a fair fixed monthly fee upfront, with no surprises.
Yes — and it's easier than you'd think. We contact your existing accountant, request your records and manage the whole handover for you. In most cases you barely have to do a thing.
Not at all. Many clients we handle entirely by phone, email and post. You're very welcome to visit us in Stanmore if you'd prefer to meet face to face.
Limited companies, sole traders and partnerships, landlords, contractors and freelancers, and start-ups — across many different industries. Not sure if we're a fit? Just call and ask.
Once we have your figures, most returns are prepared quickly — several clients have had theirs filed within the same week. The earlier you get in touch before the deadline, the smoother it is.
Yes. We're Chartered Certified Accountants, and Harrow Accountants and Tax Advisors Ltd is registered with Companies House (no. 09623931). You're welcome to look us up on the public register any time.
