If your TikTok Shop or creator turnover topped £50,000 in the 2024/25 tax year, the way you report your income to HMRC changes on 6 April 2026. You will be one of roughly 860,000 sole traders and landlords in the first wave of Making Tax Digital for Income Tax (MTD for ITSA). That means digital record-keeping, MTD-compatible software, and four quarterly updates a year on top of your year-end finalisation, instead of a single Self Assessment return. This guide explains exactly who is caught, the number that triggers it, and what to do before April.
What is MTD for Income Tax?
Making Tax Digital for Income Tax is HMRC's new way of running Self Assessment for the self-employed and landlords. Instead of filing one annual return after the tax year ends, you will:
- Keep your business records digitally (no more shoebox of receipts or a once-a-year spreadsheet bash);
- Send HMRC a quarterly update of your income and expenses through compatible software;
- Finalise the year with a final declaration that replaces the old SA100, where you confirm the figures and claim any reliefs.
The headline change is rhythm. You go from one filing event a year to five touchpoints — four quarterly updates plus the final declaration. For a TikTok seller juggling settlement reports, returns and platform fees, that means your bookkeeping has to be current all year, not reconstructed in January.
The £50,000 trigger — and it's GROSS turnover, not profit
This is the single most misunderstood point, so read it twice. The MTD threshold is based on your qualifying income, which is your gross trading turnover before you deduct a single expense. It is not your profit, and it is not what landed in your bank.
For 6 April 2026, HMRC assesses your qualifying income from your 2024/25 Self Assessment return — the one due by 31 January 2026. If your combined gross self-employed and property income on that return is over £50,000, you are mandated into MTD from the start of the 2026/27 tax year.
The threshold then steps down:
- Over £50,000 — mandated from 6 April 2026;
- Over £30,000 — mandated from 6 April 2027;
- Over £20,000 — mandated from 6 April 2028.
Because the figure is gross turnover, a creator with thin margins can easily be caught. If TikTok Shop shows £55,000 of sales but your real profit after stock, fees and refunds is £18,000, you are still in MTD — the £55,000 is what counts. The same logic that trips people up on the TikTok Shop VAT threshold applies here: thresholds bite on turnover, not on what you keep.
What counts as your TikTok turnover for MTD?
Add up the gross income from your trade before deductions. For most TikTok businesses that includes:
- Product sales through TikTok Shop — the gross order value, not the net settlement after fees and commission;
- Affiliate and creator commission from promoting products;
- Brand and PR deals, sponsored content and gifted-then-paid arrangements;
- LIVE gifts converted to diamonds and cashed out, where this is part of a trade.
Two important nuances. First, your gross turnover for MTD is the order value before TikTok takes its cut — don't make the mistake of only counting the money that hit your bank after fees. Get the basis right by working from your TikTok Shop settlement report. Second, money that isn't yours doesn't count: a customer's payment held as a deposit isn't turnover until the sale completes.
One area to watch is affiliate commission. The MTD turnover test uses gross income regardless of VAT scope, but be aware that for VAT purposes commission billed to an overseas business is outside the scope of UK VAT — it still counts as income for income tax and MTD, but not toward your £90,000 VAT registration threshold. Keep the two thresholds clearly separate in your head.
Worked example: a creator at £62,000 turnover
Meet Priya, a sole-trader TikTok creator, for the 2024/25 tax year:
- TikTok Shop product sales (gross order value): £41,000
- Affiliate commission from UK brands: £14,000
- Sponsored brand deals: £7,000
- Gross qualifying turnover: £62,000
Her allowable expenses — stock, shipping, TikTok fees, equipment, a share of phone and home costs — come to £29,000, leaving a profit of £33,000.
MTD position: Her qualifying income is the £62,000 gross figure, comfortably over £50,000. She is mandated into MTD for Income Tax from 6 April 2026, even though her profit is only £33,000. From that date she must keep digital records and submit quarterly updates.
Her 2026/27 tax bill (on £33,000 profit), for context:
- Personal allowance £12,570, so taxable profit = £20,430;
- Income tax at 20% on £20,430 = £4,086;
- Class 4 NIC at 6% on profits between £12,570 and £33,000 (£20,430) = £1,225.80;
- Class 2 is not compulsory — her profit is above the £7,105 Small Profits Threshold, so she gets a qualifying year for State Pension with nothing to pay.
So her total income tax and NIC is around £5,311.80. The amount of tax hasn't changed because of MTD — what changes is that she now reports it digitally across four quarters plus a final declaration, rather than in one annual return. If Priya gets her allowable expenses recorded properly in software as she goes, the quarterly updates become a near-automatic by-product of good bookkeeping.
The quarterly updates and digital records
Under MTD you send a cumulative update for each standard quarter. The quarters and their standard deadlines are:
- Quarter 1: 6 April – 5 July, filed by 7 August;
- Quarter 2: 6 April – 5 October, filed by 7 November;
- Quarter 3: 6 April – 5 January, filed by 7 February;
- Quarter 4: 6 April – 5 April, filed by 7 May.
These updates are summary totals of income and expenses — they are not mini tax bills, and you are not paying tax four times a year. Your payment dates stay as they are: 31 January, plus the 31 July payment on account if you make them. After your four quarters you submit a final declaration by 31 January following the tax year, where you make any adjustments, claim reliefs, and confirm the year is correct.
"Digital records" means each transaction is captured electronically in functional compatible software. For a TikTok business that is straightforward in principle but messy in practice, because your data sits across TikTok Shop settlements, payment processors and your bank. Most sellers will connect their bank feed and import settlement data so the software builds the records automatically.
MTD-compatible software — what you actually need
You cannot file MTD updates from a plain spreadsheet on its own. You need MTD-compatible software that can keep digital records and submit to HMRC's systems. In practice you have two routes:
- Full cloud bookkeeping software (the mainstream accounting packages) that records transactions and files updates directly; or
- A spreadsheet plus bridging software that pulls the totals and submits them — workable, but you still need digital links, not manual retyping.
HMRC publishes a list of compatible products. Whichever you choose, the key is getting your TikTok data flowing in cleanly — fees, commission and refunds correctly categorised — so the numbers you file are right. This is also the moment many sellers reassess whether a sole trader set-up still suits them, or whether the limited company route makes more sense, since MTD for ITSA applies to sole traders and landlords, not companies.
Don't forget: TikTok already reports you to HMRC
MTD lands at the same time as tighter platform reporting. Since 1 January 2024, under the OECD digital platform reporting rules (what people call DAC7), platforms such as TikTok Shop must collect and report each seller's income and identity details to HMRC every year. The first reports, covering 2024, were due by 31 January 2025, so your 2025 figures are reported by 31 January 2026. HMRC cross-checks that data against your tax return.
The practical upshot: HMRC can see your TikTok turnover independently. If you were ever tempted to under-report, MTD plus platform reporting closes the gap. Get your numbers clean now.
How to prepare before 6 April 2026
- Check your 2024/25 turnover. Total your gross self-employed and property income on the return due 31 January 2026. Over £50,000 means you're in from April 2026.
- Choose and set up MTD-compatible software now. Don't wait until your first quarter is already running. Connect bank feeds and TikTok settlement imports early.
- Get your record-keeping digital today. Even if you're under £50,000 this year, the £30,000 threshold from 2027 and £20,000 from 2028 will catch most growing creators soon.
- Separate VAT and MTD thinking. The £90,000 VAT threshold and the £50,000 MTD threshold are different tests on different figures. Don't conflate them.
- Reconcile returns and refunds properly so your turnover isn't overstated by sales that were later refunded.
- Talk to an accountant if you're near the line. Whether you sign up voluntarily, how to handle agent access, and getting software configured for TikTok data are all worth getting right first time.

Frequently asked questions
Is the MTD £50,000 threshold based on my profit or my turnover?
It is based on your gross qualifying income — your total trading and property turnover before you deduct any expenses. A TikTok creator with £55,000 of gross sales but only £18,000 profit is still over the £50,000 threshold and is mandated into MTD for Income Tax from 6 April 2026.
When exactly do I have to start using MTD for Income Tax?
If your qualifying income on your 2024/25 Self Assessment return (due 31 January 2026) was over £50,000, you must use MTD from 6 April 2026. The threshold then drops to over £30,000 from 6 April 2027 and over £20,000 from 6 April 2028, pulling in many more creators.
Does MTD mean I pay tax four times a year?
No. The quarterly updates are summaries of your income and expenses, not tax payments. Your payment dates stay the same — 31 January and any 31 July payment on account. You still settle your bill once a year after submitting a final declaration.
Can I keep using a spreadsheet for my TikTok bookkeeping under MTD?
Only if you combine it with MTD-compatible bridging software that can submit to HMRC, and you maintain digital links rather than retyping figures. Most TikTok sellers find full cloud bookkeeping software easier because it can import bank feeds and settlement data automatically.
