Allowable expenses, ad spend and pass-through costs, gifted products, sole trader vs limited company, VAT and MTD explained for UK social media managers.
A social media manager's tax position is unusual among service freelancers because so much of the money moving through the business is not actually theirs. You might receive a GBP 5,000 monthly retainer that includes GBP 3,500 of Meta and TikTok ad budget you spend on the client's behalf, leaving GBP 1,500 of real fee. If you record the GBP 5,000 as income and forget to log the GBP 3,500 of ad spend, your turnover looks inflated, you risk crossing thresholds you have not really reached, and your tax bill is wrong. Get the pass-through treatment right and almost everything else falls into place.
Alongside that, SMMs deal with gifted products in exchange for content, a mix of agency subcontracting and direct clients, and a kit of phones, cameras and software that blurs the line between business and personal. This guide works through each of those, plus the structure question that gets sharper once ad budgets make your numbers look bigger than they are.
As a sole trader you pay Income Tax on profit, which is your total income minus allowable expenses. For 2025/26 the first GBP 12,570 is covered by the personal allowance, then 20% to GBP 50,270, 40% to GBP 125,140 and 45% above, with the personal allowance tapering away between GBP 100,000 and GBP 125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, with Class 2 NIC settled through Self Assessment.
Scottish SMMs pay Scottish Income Tax through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance is UK-wide. Welsh SMMs have a C-coded tax code at rates currently matching the rest of the UK. If a part-time job or a client is distorting your code, run it through the tax code checker.
This is the single most important concept on the page. When a client funds advertising that you run, that money is a pass-through cost, not your earnings. There are two clean ways to handle it:
Why it matters so much: a few clients with healthy ad budgets can make your gross turnover look like it is approaching the GBP 90,000 VAT threshold or an MTD band when your real fee income is a fraction of that. Recording pass-through spend properly keeps your numbers honest and your structure decisions sound.
Most SMMs blend several sources of income, and they stack on top of each other. The multiple-income tax calculator shows the combined picture.
| Income type | How it is taxed | Watch out for |
|---|---|---|
| Direct client retainers | Self-employment trading income | Record the fee, log any pass-through ad spend separately |
| Agency subcontracting | Trading income; you invoice the agency | Confirm you are a contractor, not a disguised employee |
| One-off campaigns and launches | Trading income | A single big launch month can tip you into a higher band |
| Gifted products and trips | Trading income at cash value | Easy to forget; record the market value when received |
| Affiliate and commission income | Trading income | Often paid through platforms, simple to overlook |
| Part-time PAYE or other job | Employment income, taxed at source | May already use your personal allowance |
If you subcontract heavily to one agency, sitting in their team, on their tools, taking their direction, be aware that employment-status questions can arise. A genuine freelancer with several clients and control over how the work is done is clearly self-employed; an embedded, single-client arrangement is worth a sense-check.
SMMs and the creators they work with are often sent products, services or trips in exchange for posting about them. HMRC generally treats these as taxable trading income at their cash value, because they are received in return for your professional services. You can then deduct the genuine business element, but the receipt itself is income. A no-strings gift from a friend is different, but anything provided because of your work counts. Keep a running note of the market value of significant gifts; a wardrobe of sent products or a funded trip can add up to a meaningful number by April.
An expense is allowable when incurred wholly and exclusively for the business. The SMM's list mixes software, content kit and home-office costs.
| Expense | What qualifies | Notes |
|---|---|---|
| Computer and devices | Laptop, monitor, phone used for content and management | Apportion any private use; business share via AIA |
| Content kit | Camera, ring light, tripod, microphone, lighting | Allowable where used for client content |
| Software and tools | Scheduling, analytics, design, editing, link-in-bio, CRM | Subscriptions are fully deductible |
| Stock and licences | Stock images, music and font licences for posts | Deductible cost of producing content |
| Your own advertising | Ads promoting your own SMM services | Deductible; distinct from client ad spend |
| Home-office costs | HMRC flat-rate working-from-home allowance, or a fair proportion of heat, light, broadband, rent or mortgage interest | Choose the larger fair deduction |
| Subcontractors | Editors, designers or junior creators you pay | Direct cost of delivering the work |
| Professional indemnity insurance | Cover for contract and content claims | Fully deductible |
| Training and CPD | Courses that develop your existing skills | Training into a new trade is not allowable |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
A phone is the classic SMM grey area: it is genuinely a work tool for shooting and posting content, but it is also your personal phone. Claim a fair business proportion, not the whole cost. The same applies to a camera or laptop the household also uses. For home working, choose between HMRC's simplified flat rate based on hours worked at home and an actual proportion of household running costs; a full-time home-based SMM usually gains more from the actual-cost method.
The private share of dual-use phones, devices and broadband must be excluded. Everyday clothing is never allowable even when bought to look the part on camera. And client ad spend is a pass-through, not your cost, so it is recorded against the matching income, not claimed as a standalone expense reducing your fee.
For most SMMs the decision turns on profit and on how distorted the numbers look. Below roughly GBP 30,000 to GBP 40,000 of genuine profit, sole trader is usually simpler and cheaper. As profit rises into higher-rate territory a limited company can be more tax-efficient through a small salary plus dividends, and it ring-fences liability, which some SMMs value when they are spending large client ad budgets. The trade-off is corporation tax, payroll, statutory accounts and a Confirmation Statement. Where big pass-through budgets inflate turnover, a company can also keep your personal and business finances cleanly separated. Run your real figures through the Ltd-versus-sole-trader comparison before deciding, and the sole trader tax calculator to see your current position.
Take a home-based social media manager with three retainer clients. The retainers total GBP 78,000 received, but GBP 36,000 of that is client ad spend that passes through their account, leaving GBP 42,000 of genuine fee income.
Income (fees only, after recording pass-through both sides): GBP 42,000
Allowable expenses:
Taxable profit: GBP 42,000 minus GBP 9,000 = GBP 33,000
Income Tax: GBP 33,000 minus GBP 12,570 = GBP 20,430 at 20% = GBP 4,086
Class 4 NIC: GBP 20,430 at 6% = GBP 1,226
Total tax and NIC: GBP 5,312 for the year. Note that the GBP 36,000 of pass-through ad spend, recorded as both income and an offsetting expense, has no effect on profit, but it does push gross turnover toward GBP 78,000, which matters for the VAT and MTD threshold tests below.
For a social media manager, the first job is separating the money you spend for clients from the money you actually earn. Mix the two and every later decision, VAT, structure, MTD, is built on a false number.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period. Here pass-through spend bites again: if client ad budgets flow through your accounts, your gross turnover can approach GBP 90,000 even when your fee income is far lower. Whether that pass-through counts toward your VAT turnover depends on whether it is a true disbursement met on the client's behalf or part of your own supply, which is exactly why funding ad accounts directly from the client is the cleaner model. If you do register, and your clients are VAT-registered businesses, they reclaim the VAT you charge and you reclaim VAT on software and kit, so registration is relatively painless. SMMs serving small non-VAT clients should weigh the price impact before registering voluntarily.
Making Tax Digital for Income Tax Self Assessment replaces the annual return with quarterly digital submissions and a year-end finalisation. The thresholds are on gross income, not profit:
Because the test is on gross income, an SMM with large pass-through ad budgets may cross a threshold sooner than their real earnings suggest, so keeping client spend clearly separated in your records is not just tidy, it affects when MTD applies to you. The upside is that recording income and ad spend digitally as they occur is far easier than reconstructing tangled retainer-plus-budget figures at year end.
Netting off client ad spend invisibly. Record both the budget received and the spend made so they cancel out. Leaving both off understates turnover and breaks your VAT and MTD figures.
Forgetting gifted products and trips. Items received in exchange for promotion are taxable at their cash value. Log the market value of significant gifts when they arrive.
Claiming the whole phone or laptop. Devices used personally as well as for work must be apportioned to the business share.
Confusing your own ad spend with the client's. Advertising your own services is deductible; client ad budget is a pass-through, not a cost that reduces your fee.
Misreading turnover because of pass-through. Large budgets flowing through your accounts can make you think you have hit VAT or MTD thresholds on earnings you never actually made. Track fees and pass-through separately.
