Which workbook fits your situation? An honest chooser — including "none"
Last verified: 24 August 2026, against the cited gov.uk sources.
Brit Design makes five workbooks, each for a different UK tax or compliance regime — and some situations genuinely need none of them. The quick version: casual online sellers get Seller's Ledger UK (£9) or possibly nothing; a normal 2025-26 Self Assessment is SA Sorted (£14); the first post-FHL holiday-let return is Host Sorted (£14); quarterly Making Tax Digital reporting is MTD Ready (£14); and Renters' Rights Act compliance tracking for England landlords is Let Sorted (£9). Each answer page on this site gives you the underlying rules free, whether or not you buy.
First: the cases where you may not need any of them
- You only sell your own old stuff. HMRC's guidance says selling personal possessions probably creates no Income Tax bill, no matter the amount (gov.uk). A ledger's only value to you is evidence and peace of mind — HMRC's free online checker may be all you need.
- Your gross trading income is £1,000 or less per tax year. The trading allowance covers it; you normally don't need to tell HMRC at all (gov.uk). You must still keep records — but a free sheet of paper technically qualifies.
- You already have an accountant or accounting software. These workbooks are for people doing their own records. If your records are already kept properly elsewhere, a workbook duplicates them.
- Your rental is in Wales, Scotland or Northern Ireland. Let Sorted is England-only — the devolved rules differ, and the product says so on its first page.
- Your situation is complicated. Capital allowances on big equipment, losses, CGT on a property sale, contested possession — the products themselves flag these as accountant or solicitor territory. A £9–£14 spreadsheet should not pretend otherwise.
The decision table
| Your situation | What applies to you | Fit |
|---|---|---|
| You sell on Vinted/eBay/Depop; mostly your own things, or a small side trade; not sure where you stand with HMRC letters | The £1,000 trading allowance and the 30-sales/€2,000 platform-reporting rule — two thresholds on two calendars (our answer page) | Seller's Ledger UK (£9) — or nothing, if it's all personal possessions |
| Sole trader or employed side-hustler, gross trading income over £1,000 in 2025-26, filing Self Assessment | Register by 5 Oct 2026; SA103 boxes; Payments on Account (our answer page) | SA Sorted (£14) |
| UK holiday-let owner (Airbnb, Vrbo, Sykes, Booking.com or direct) filing the 2025-26 return | First return after the FHL abolition: 20% interest credit, RDIR, the transition rules (our answer page) | Host Sorted (£14) |
| Sole trader or landlord with qualifying income over £50,000 in 2024-25 (or over £30,000 in 2025-26, from April 2027) | Making Tax Digital: digital records + cumulative quarterly updates through software (our answer page) | MTD Ready (£14) + bridging software (~£30/yr; free options exist) |
| Self-managing landlord with 1–10 properties in England | The Renters' Rights Act regime: Section 13 records, certificates, the PRS database (our answer page) | Let Sorted (£9) |
Common combinations and edge cases
"I'm a seller whose trading passed £1,000." You've outgrown tracking-only: you need to register for Self Assessment by 5 October after the tax year and file. SA Sorted is the filing workbook; Seller's Ledger remains useful in-year for the platform-reporting side, but if you're buying one, buy SA Sorted.
"I'm a landlord with a normal buy-to-let, not a holiday let." Host Sorted is specifically built around the FHL abolition transition (the 20% credit calculator applies to any residential landlord, but the box mapping and guide are holiday-let-shaped). For compliance duties on an English let, Let Sorted is the fit; for the tax return itself with straightforward property income, HMRC's free online return plus the SA105 notes may be all you need.
"I have a trade AND a rental." Under Self Assessment they're separate pages of one return (SA103 + SA105). Under MTD they're separate quarterly income sources — MTD Ready handles both self-employment and UK property tabs in one workbook. And remember the MTD threshold tests your combined gross income (gov.uk): £25,000 of rent plus £27,000 of turnover is over £50,000 even though neither is alone.
"Which comes first, SA Sorted or MTD Ready?" Check your qualifying income. Over £50,000 in 2024-25: you're already in MTD (since April 2026) — MTD Ready. Over £30,000 in 2025-26: the 2025-26 return is your last normal Self Assessment cycle — SA Sorted now, MTD Ready from April 2027. Under £20,000: MTD isn't mandated on the currently published timetable at all (gov.uk).
"Holiday-let owner AND England landlord duties?" They're different regimes: Host Sorted covers the tax return, Let Sorted covers the compliance duties (gas, EICR, deposits, the PRS database). Some duties differ for holiday accommodation — Let Sorted is built around ordinary residential tenancies.
What all five have in common
- Every fact cited. Each product's guide cites every factual claim inline to gov.uk, legislation.gov.uk or HSE, checked on a stated date, with a claim-by-claim source table (SOURCES.md) in the download.
- No macros. Standard spreadsheet functions only — Excel, Google Sheets and LibreOffice, with import instructions included.
- A "what it does NOT do" section on every listing. None of them file with HMRC. None calculate advice. All say so.
- AI-assisted, human-directed, disclosed. And a fix-it-or-refund policy: if a file doesn't open or work as described, email mybritdesign@gmail.com.
