This relaxed rundown (around 1980 words) chats straight for everyday property punters like you landlords with a couple of flats, flippers, or families with a buy-to-let not tax wizards. We’ll unpack legit strategies, costs, risks, and tables to spot easy wins. No dodgy schemes; just smart, above-board moves to make your bricks work harder. Fancy saving £5K-£20K next year? Grab a brew; let’s dive into the numbers.
Why Tax Planning’s a Must for UK Property Owners in 2026
Property taxes hit hard 40-45% on rental profits for higher earners, 18-28% CGT on sales, plus 3-12% stamp duty upfront. But reliefs like full corporation tax deduction for ltd co mortgages (vs none personally) flip the script. 2026 changes: EPC C mandates add £5K costs (deductible), ATED thresholds rise to £600K, and IHT nil-rate bands freeze at £325K. Net result? Plan now or pay later. Average landlord saves £3K-£7K/yr via structures. Pitfall? Overlooking admin (£1-2K/yr). Start with an accountant chat £500 consult pays itself.
Limited Companies: The Game-Changer for Rental Income Tax
Personal BTL? No mortgage interest relief since 2020 tax on full rent, deduct 20% credit. Ltd co? Corporation tax 19-25% on profits, full interest deductible. Example: £20K rent, £12K mortgage personal tax £2.8K (40%), ltd co £1.6K (25%). Transfer prop? CGT + SDLT hit (£10K+), but pooling future buys stamp-free.
