Introduction
If the thought of tackling your tax return or limited company accounts makes you break into a cold sweat, you’re not alone. I’m The Tax Girl – your friendly online accountant and founder of Simple Taxes. My mission is simple: to make tax for small business owners less scary, less stressful, more affordable, and (dare I say it)… maybe even a little bit fun.
Whether you’re a sole trader, a limited company director, or just trying to survive the annual Self Assessment deadline without losing your mind, I’ve got you covered.
Why choose an online accountant?
The days of dragging your paperwork across town to meet a grey-suited accountant are over. With Simple Taxes, everything is handled online – quick, secure, and stress-free. You get:
💬 Year-round tax support (not just in January panic mode)
🗣 Clear, plain-English advice (no jargon, I promise)
💷 Fixed fees so you know exactly what you’re paying
💻 Flexible communication – email, video calls, WhatsApp – whatever works for you
Whether you’re submitting a Self Assessment tax return or managing limited company accounts, online accounting saves you time and keeps your finances in order without the faff.
Self assessment tax returns - made simple
If you’re self-employed, earning rental income, or have side hustle earnings, you’ll know that Self Assessment season can feel overwhelming.
At Simple Taxes, I handle:
🆔 HMRC registration for Self Assessment
🧮 Calculating exactly what you owe (and making sure you claim every allowance you’re entitled to)
📤 Submitting your tax return on time, so you avoid late penalties
📅 Ongoing reminders and tips to help you stay ahead of the game
No last-minute panic, no confusing HMRC forms – just peace of mind that it’s done right.
Online accountant for sole traders
Running your own business as a sole trader is exciting – but the bookkeeping and tax admin? Not so much.
I help sole traders with:
📂 Keeping business and personal finances organised
💰 Claiming expenses correctly to reduce tax bills
🖥 Staying on top of Making Tax Digital requirements
📈 Year-round advice to keep you compliant and profitable
From your first invoice to your final tax return of the year, I’m here to make sure your numbers are neat and your tax bill is fair.
Online accountant for limited companies
If you’re a limited company director, you’ll know that the accounting rules can be a little… intense.
That’s where I come in. I can help you with:
📑 Annual accounts and Corporation Tax returns
🧾 Director’s Self Assessment
💸 Payroll and dividend planning to keep your income tax-efficient
💼 VAT returns and registration
📊 Clear strategies to take home more money, legally and sensibly
With Simple Taxes, you get a partner who understands both the numbers and the business realities of running a company.
Online accountant for landlords
If you own property and earn rental income, keeping on top of your tax obligations can be a real headache – especially with Making Tax Digital on the horizon.
I help landlords with:
🏘 Calculating rental profits (including allowable expenses and mortgage interest relief)
📝 Preparing and submitting your Self Assessment tax return
💡 Claiming all eligible property-related deductions
📂 Guidance on record-keeping and compliance with HMRC requirements
🔮 Planning for future tax changes that could impact landlords
Whether you have a single rental or a growing portfolio, I’ll make sure your property income tax is accurate, compliant, and as tax-efficient as possible.
Common small business expenses you can claim
One of the easiest ways to reduce your tax bill is by claiming all the allowable business expenses you’re entitled to. Here are some common ones for small businesses and self-employed individuals:
💼 Office costs (rent, utilities, stationery, software subscriptions)
🚗 Travel expenses (mileage, parking, train or bus fares for business journeys)
📢 Marketing costs (website hosting, advertising, design work)
📑 Professional fees (accountant, solicitor, business advice)
💻 Equipment (laptops, tools, machinery)
📱 Phone and internet bills (business portion)
📚 Training and professional development
🏠 Work from home allowance (if applicable)
Claiming correctly means you keep more of your hard-earned income – and I’ll make sure nothing gets missed.
As my client, you'll get these services as standard
For a small monthly fee, you’ll get full, year-round accounting support – perfect for sole traders, landlords, and limited companies who want peace of mind and a friendly accountant on hand whenever questions pop up.
