Salon Owner Tax Prep: The 8 Numbers You Need Before April
Most salon owners hand their accountant a shoebox. Here's how to hand them a spreadsheet — and why it saves you money.
Tax preparation for a salon is not complicated — but it is consequential. Salon owners who track the right numbers year-round spend around two hours preparing for their accountant. Those who don't spend two weeks trying to reconstruct a year of expenses from memory and bank statements. The difference in accountancy fees alone often exceeds £500. More importantly, the owners who track well consistently claim more legitimate deductions — not through creative accounting, but because they have the records to support claims that others lose by default.
The 8 Numbers Your Accountant Needs
Before you sit down with your accountant — or file yourself — you need these eight figures prepared and documented. If you're tracking these month by month, year-end takes an afternoon. If you're not, it takes a week.
| # | Number | Where to Find It |
|---|---|---|
| 1 | Total gross revenue (services + retail) | Your booking software year-end report |
| 2 | Total payroll paid (wages + employer NI) | Payroll software or HMRC submissions |
| 3 | Total product/retail cost of goods | Supplier invoices + opening/closing stock |
| 4 | Rent and rates paid | Lease agreements + council tax bills |
| 5 | Utilities (electricity, water, broadband) | Direct debit statements or supplier accounts |
| 6 | Equipment purchases and repairs | Receipts — any item over £50 needs a receipt |
| 7 | Marketing and software spend | Bank statements, subscription summaries |
| 8 | Mileage and travel (if applicable) | Mileage log — required for any vehicle deduction |
These eight numbers cover the core of a salon's profit and loss. Your accountant will add depreciation, any loan interest, and business-specific items — but they need these foundations clean and documented before they can do anything useful.
Categorising Expenses: What Counts and What Doesn't
The most consistent mistake salon owners make is either overclaiming (personal expenses run through the business) or underclaiming (legitimate business expenses not recorded because the owner assumed they weren't deductible). Both are costly. Here is a clear breakdown of the main categories:
Clearly deductible: rent, rates, utilities for the business premises; all staff wages and employer NI contributions; product costs and professional supplies; insurance (public liability, employer's liability, contents); booking software and business subscriptions; professional development and training courses; accountancy and legal fees; business bank charges; marketing and advertising spend; uniform and PPE; equipment used exclusively for the business.
Partially deductible (requires allocation): phone bills (the business-use percentage); vehicle costs (business mileage only — requires a log); home office costs if you do administrative work from home (the calculated proportion of household costs).
Not deductible: personal clothing (even if you only wear it at the salon — clothing must be a uniform or PPE); client gifts over £50 per person per year; entertainment expenses (client lunches, team nights out); fines and penalties; depreciation on personal assets used occasionally for the business.
The receipt rule: any single expense over £50 needs a receipt. For expenses under £50, a bank statement entry is usually sufficient. Keep receipts in a dated folder — physical or digital. Photograph paper receipts immediately; thermal paper fades within 18 months and is unreadable by the time HMRC asks for it.
Staff vs Contractor: The Distinction That Matters
This is the area where salon owners most frequently get into trouble. HMRC has specific tests for whether someone working in your salon is an employee or a self-employed contractor, and the consequences of misclassification are significant: backdated employer NI, income tax liability, and potential penalties.
The key indicators of employment (not contractor status) are: the person works set hours you determine; they use your equipment and products; you direct how and when the work is done; they cannot send a substitute; and they are economically dependent on your salon as their primary income source. If most of these describe your "chair renters" or "self-employed" stylists, HMRC may classify them as employees.
Genuine contractor relationships in salons typically look like this: the stylist sets their own hours, uses their own products, bills you (or clients directly) by invoice, works for multiple salons or clients, and bears their own financial risk. If that describes your arrangement, you're likely on solid ground. If it doesn't, take legal advice before your next filing — the cost of the advice is far less than a misclassification dispute.
The practical implication: for any worker you pay more than £1,000 per year, document the arrangement. A written agreement specifying the nature of the relationship — employment contract or contractor agreement — is your first line of defence.
Quarterly Payments: Why You Should Pay Before You're Made To
If you're self-employed or a director drawing income from a limited company, tax is not deducted at source — you owe it at the end of the year and need to make payments on account. Many salon owners discover this only after their first year of trading, when a bill arrives that they hadn't budgeted for. The answer is to make voluntary quarterly payments throughout the year.
A simple approach: at the end of each quarter, transfer 25–28% of your net profit (revenue minus expenses) into a separate tax savings account. Do not touch it. When the bill arrives, you have most or all of it already set aside. The alternative — paying in one lump sum in January — requires either that level of cash available at once, or that you borrow. Neither is better than the quarterly set-aside.
If your business is VAT-registered (required once turnover exceeds £90,000 in the UK), you're already making quarterly submissions to HMRC. Use those same quarterly windows to also review your income tax position and top up your set-aside if needed.
What to Hand Your Accountant: The Folder Structure
The difference between a two-hour accountant meeting and a three-day one is how organised your records are. Prepare one folder — physical or digital — for each tax year, containing the following sections: income (booking software report plus any cash received), payroll records (payroll software export or HMRC PAYE submissions), supplier invoices (sorted by category), bank statements (all business accounts, full year), and a one-page summary of the eight numbers above.
If you use accounting software such as Xero, QuickBooks, or FreeAgent, the year-end export from those systems largely replaces the manual folder — but only if you've been categorising transactions correctly throughout the year. An accountant working with clean, categorised software data charges significantly less than one untangling a year of uncategorised transactions. The monthly hour you spend keeping records current is worth several hundred pounds at year-end.
The Year-Round Habit That Makes This Easy
The salon owners who find tax season least stressful share one habit: they spend 30 minutes at the end of each month on their finances. Not deep analysis — just three tasks. First, reconcile the business bank account (check every transaction is accounted for). Second, file any physical receipts received that month. Third, note any unusual expenses or income that the accountant should know about.
That's 6 hours across the year. It produces clean, complete records. It means no reconstruction in January, no "I think I spent about this much on products," and no overlooked deductions. If you're not doing this yet, start now — it's never too late in the year to catch up on the previous months, and any improvement from this point forward reduces your year-end workload.
