SA800 supplementary pages (SA801-SA804)

Land & Property, Foreign, Chargeable Assets and Savings on one screen - each page files only when it carries figures, and the totals calculate themselves.

Beta feature — Partnership (SA800) returns are in beta and open to everyone — accountant firms and partnerships filing their own return — for the 2025-26 tax year. If anything looks wrong, email support@taxoptimiser.co.uk and the team will help.

Partnerships with income beyond the trade report it on the SA800’s supplementary pages. The Supplementary step gathers all four on one screen; a page is only included in the submission when it actually carries figures, and the Review step lists which pages will go (“Supplementary pages with data”).

The Supplementary step: Land & Property (SA801), Foreign (SA802), Chargeable Assets (SA803) and Savings (SA804) groups

Every figure on these pages is carried to the Partnership Statement and shared between the partners by their profit share % on the Partners step — each box’s hint says which statement box it feeds.

Land & Property (SA801)

  • Income: rents and other income (1.21), any tax deducted from it (1.22), chargeable premiums (1.23) and reverse premiums (1.23A).
  • Expenses (1.25–1.30): rent, rates and insurance; repairs and maintenance; non-residential finance costs; legal and professional costs; cost of services provided; and other allowable expenses. Net profit/(loss) (1.32) is calculated.
  • Tax adjustments: private use (1.33) and balancing charges (1.34) add back; the Annual Investment Allowance (1.35A), the other allowances (1.35B–1.36) and the cost of replacing domestic items (1.37) deduct. Profit/(loss) for the return period (1.39) is calculated from them and feeds statement box 19.
  • Residential finance costs (1.40) — mortgage interest and similar costs on residential lets are not an expense. Enter them here and each partner receives their share in statement box 26 to claim the basic-rate tax reduction on their own return.

Under the grid, tick traditional (accruals) accounting (box 1.22A) if the property income is not on the cash basis — the Annual Investment Allowance on property can only be claimed with it.

Foreign (SA802)

Foreign savings income (rows 2.2) and foreign dividends (rows 2.2A) are entered one row per country — up to 20 of each — with the amount before foreign tax and the foreign tax paid. Tick Unremittable for income that can’t be brought to the UK: it is reported, but left out of the totals (2.6, 2.6A, 2.8) and the Partnership Statement. Foreign tax cannot be entered without the income it was paid on.

Foreign savings income by country: France, Germany and an unremittable row for Brazil, each with the gross amount and foreign tax Foreign dividends by country: one row for the United States with the gross dividend and foreign tax

Land and property abroad: add a letting for each overseas let property (up to six), with its country, address, rents, expenses and tax adjustments — one SA802 page PF3 each. Several properties in the same country with no foreign tax can share one letting with “more than one property” ticked. The adjusted profit or loss of each letting is calculated; the remittable lettings are pooled into a taxable profit (copied to box 2.7 and statement box 17) or an allowable loss (box 2.10 and statement box 21). With more than one letting and a loss among them, enter each profitable letting’s amount chargeable after setting the loss against it — normally against the country with the lowest rate of foreign tax first. Residential finance costs go to box 2.10A and statement box 27. Chargeable premiums, offshore fund disposals (box 2.9 → statement box 18) and the traditional accounting tick (2.8A, needed once rents and balancing charges pass £150,000) sit under the lettings.

A foreign letting: country, the more-than-one-property and unremittable ticks, the property address and the income and expenses boxes 2.11 to 2.18 The letting result: net profit 2.19 and adjusted profit 2.26/2.27 calculated, with the foreign tax, residential finance costs and amount chargeable boxes The foreign property result: the pooled taxable profit or loss, chargeable premiums, box 2.7, offshore fund disposals and residential finance costs

Chargeable Assets (SA803)

The supplementary page details: the SA801 traditional accounting tick, the SA802 countries and the SA803 list of disposals

The partnership reports only the disposal proceeds from chargeable assets sold in the period. That is deliberate — a partnership isn’t itself chargeable to capital gains tax, so each partner computes their own gain or loss on their share via their personal return.

You can type a single total in box 4.1, or click Add disposal to list each asset with a description, a tick for unquoted shares, its proceeds and any further information (up to 50 rows, 80 characters each). Once disposals are listed, box 4.1 becomes their calculated total.

Savings (SA804)

  • UK bank and building society interest (gross) — filed as untaxed interest unless you also enter tax deducted, in which case it is filed as taxed interest. HMRC requires the tax to be 20% of the gross, to within £1.
  • National Savings & Investments interest (7.4).
  • Dividends from UK companies and unit trusts, stock dividends and bonus issues (7.19–7.22).
  • Other income: without tax deducted, as a profit (7.26) or a loss (7.27) but not both; or with tax deducted (7.30 gross and 7.29 tax, again 20%).

Like the main pages, anything the form derives is calculated read-only, and leaving a page untouched simply leaves it out of the filing — there is nothing to switch on or off.

Next: review, print and submit to HMRC.

The short version

SA800 supplementary pages (SA801-SA804) — in brief

The four SA800 supplementary pages are entered on one Supplementary step.

A page is included in the HMRC submission only when it carries figures; the Review step lists which will go.

SA801 (property) has its expense and tax-adjustment boxes, with residential finance costs carried to each partner in statement box 26.

SA802 covers foreign savings and dividends; SA803 lists disposals, proceeds only; SA804 covers interest, dividends and other income.
