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

The decision table

Your situationWhat applies to youFit
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.
