Why Old Windsor businesses choose PJFL

Two incomes, one tax return

Old Windsor is full of people with a job and something else running alongside it — a trade at weekends, consultancy in the evenings, a shop on a marketplace site. The questions are always the same: whether the thousand pound trading allowance covers it, at what point a side line becomes a business HMRC expects to hear about, and how the tax on it interacts with what is already being deducted under PAYE. We will tell you where the line falls and register you if you have crossed it.

Lodgers, holiday lets and the rooms in between

A village this close to Windsor and the Great Park sees a lot of letting that is not a straightforward tenancy. Rent-a-room relief covers up to seven and a half thousand pounds from a lodger and is often missed entirely; short lets through booking platforms are reported to HMRC whether or not they appear on a return; and since the furnished holiday letting rules ended in April 2025 the old advantages of that treatment have gone. We will work out which of those you are actually in.

Trades and businesses run from home

Most Old Windsor businesses operate from a house, a van or a yard rather than premises. That shapes the practical questions: what proportion of the home is fair to claim, whether a van or a car is better held personally or through a company, how to keep records without losing an evening a week, and when turnover is close enough to the VAT threshold to need watching rather than ignoring.

Contracting in the Windsor and Heathrow corridor

Between Windsor, Slough and the airport there is no shortage of contract work, and the structure you use for it matters more than the day rate suggests. Umbrella company or your own limited, whether an engagement sits inside IR35 and who decides, what you can genuinely claim while working away — we will go through it on your figures before you sign rather than after the first payslip disappoints.

How we work with you

We are in Egham, roughly three miles from Old Windsor and just over the Surrey border. Close enough to know the area, and near enough to the same commuter and trade economy that the questions are familiar ones.

Everything runs remotely — records sent across digitally, questions answered by phone, email or video call, deadlines tracked by us. Working across a county boundary changes nothing about how you are taxed or how we handle it.

Questions about accountants in Old Windsor

Are you based in Old Windsor?

We are in Egham, around three miles away on the Surrey side of the river, and we work with clients throughout Old Windsor and the Royal Borough. It is all handled remotely, so there is nothing you need to travel for.

Does it matter that you are in Surrey and I am in Berkshire?

Not at all. Income tax, corporation tax, VAT and payroll are national, so nothing about your position changes at the county line. What local means here is that we know the area and the kinds of business in it, not that a boundary has any effect on the work.

I have a job and a small business on the side. Do I need to tell HMRC?

If the income is above the thousand pound trading allowance, yes. Below it you generally do not, though there are exceptions worth checking. We will tell you which side of it you are on, register you if needed, and make sure the tax on the side income is worked out properly against the PAYE already deducted.

I let a room to a lodger. Is that taxable?

Often not, thanks to rent-a-room relief, which covers up to seven and a half thousand pounds a year and is one of the most commonly missed allowances there is. Above that, or where the letting is really a holiday let rather than a lodger, different rules apply. We will work out which applies to you and whether anything needs reporting.

Which areas around Old Windsor do you cover?

Old Windsor, Windsor, Datchet, Egham, Englefield Green, Wraysbury, Eton, Sunningdale, Virginia Water, Staines-upon-Thames and Horton, along with the rest of the Royal Borough and Runnymede.

What do you charge, and how do I move to you?

A fixed price agreed in writing before we start, based on what you need rather than an hourly rate. Moving is simple: you tell your current accountant you are leaving, we request your records and the professional clearance letter, and we handle the rest between us.
