Planning 2027: UK Bank Holidays, Tax and ISA Year-End Dates
Why 2027 Planning Matters Now
It's never too early to get your 2027 planning sorted. Whether you're self-employed, run a small business, or simply want to manage your finances more effectively, knowing the key dates ahead of time means fewer last-minute panics. Bank holidays affect when services close. Tax deadlines don't move. ISA allowances reset. Getting these on your radar now lets you plan your year with confidence.
Essential 2027 Dates You Need to Track
UK Bank Holidays in 2027
Bank holidays affect more than just having a day off. If you're self-employed or run a business, they can disrupt deadlines, client meetings, and service closures. Here's what to expect in 2027:
- 1 January – New Year's Day
- 15 April – Good Friday
- 18 April – Easter Monday
- 3 May – Early May Bank Holiday
- 31 May – Spring Bank Holiday
- 29 August – Summer Bank Holiday
- 25 December – Christmas Day
- 26 December – Boxing Day
In Scotland, Northern Ireland and Wales, there are additional local holidays. If you work across different regions or serve customers nationwide, mark these carefully.
Tax Deadlines You Can't Miss
Tax deadlines are inflexible. Missing one can mean penalties, interest, or complications. For 2027, key dates include:
- 31 January 2027: Self Assessment tax return deadline for 2025–26 tax year. This is the main filing deadline for freelancers, contractors, and anyone with additional income.
- 19 July 2026 and 19 January 2027: Quarterly tax estimates due (if you pay your tax in instalments)
- PAYE quarterly deadlines: If you run a payroll, these are typically 14th of the month following the quarter end
- VAT returns: Monthly or quarterly, depending on your VAT scheme
Different tax situations have different deadlines. If you employ staff, outsource to contractors, or trade internationally, your deadlines may vary. The key is to identify yours now and not on 30 January.
ISA Year-End: 5 April 2027
The ISA (Individual Savings Account) tax year runs from 6 April to 5 April. This means 5 April 2027 is your final deadline to use your full 2026–27 ISA allowance. You can contribute up to £20,000 across your ISA accounts in that tax year, split as you choose between Cash ISAs, Stocks and Shares ISAs, Lifetime ISAs and Innovative Finance ISAs.
If you don't use your allowance, it doesn't roll forward. So if you've been thinking about ISA investing, the April deadline is your cue to act.
How to Stay Organized
Knowing the dates is one thing; staying on top of them throughout the year is another. Here's a practical approach:
- Add all key dates to your calendar – not just the deadline, but a reminder 2–4 weeks before so you have time to prepare
- Group similar tasks: Batch tax work together. Set aside time in March for Self Assessment prep, April for ISA decisions, and May for reviewing business finances
- Keep a central reference document – One place where all your deadlines live, whether that's a spreadsheet, planner or printed sheet. Refer to it monthly
- Use a business planner – If you're juggling multiple dates, a dedicated planner takes the guesswork out and keeps everything visible
