Why Does Council Tax Go Up Every Year?
Councils in England set their budgets every winter, and by February or March they announce how much council tax will rise from the following April. The increase covers rising costs of local services — social care, waste collection, roads, libraries, and policing in some areas — while central government funding to councils has generally shrunk in real terms over the past decade. Adult social care in particular has become a huge and growing cost for many councils, which is why a specific part of the annual increase is often ring-fenced for it.
Because council tax is one of the few taxes local authorities can raise themselves (rather than relying entirely on central government grants), it tends to rise close to the maximum allowed most years, especially for councils facing budget pressure.
The 4.99% Referendum Cap Explained
In England, councils with social care responsibilities can normally increase Band D council tax by up to 4.99% in a single year without having to hold a local referendum to get residents’ approval. This is made up of two parts:
- Up to 2% — the general core increase any council can apply.
- Up to 2.99% — the “adult social care precept,” an additional amount specifically for councils that provide adult social care services.
Any rise beyond 4.99% would normally require a local referendum, which is expensive and rarely called. However, some councils facing severe financial distress have been given special one-off permission by central government to increase council tax beyond the normal cap without a referendum — this has happened in various years for individual councils dealing with budget shortfalls. These exceptions are announced council-by-council, not nationally, so if your bill has gone up by more than 4.99%, check your council’s official budget announcement or your annual bill letter to see the exact reason and figure.
Scotland does not operate under the same fixed referendum cap as England, and Welsh councils set their own increases too, so rules and typical percentages can differ if you live outside England. Always confirm the figure that applies specifically to your council and nation.
How to Find Your Council’s Exact Increase
Don’t guess — get the exact percentage from an official source before you rely on this calculator’s output for budgeting:
- Check your council’s website for its budget announcement, usually published in February or March.
- Look at your annual council tax bill letter, which arrives in March and states the new amount for the coming tax year.
- Search “[your council name] council tax increase [year]” — local news outlets usually cover the announcement too.
Once you have the percentage, plug it into the calculator above along with your current bill to see your new annual and monthly figures instantly.
What Happens If You Can’t Afford the Increase
If the new bill is a stretch, you have options before falling behind on payments:
- Council Tax Support / Reduction Scheme — most councils run a means-tested scheme that can reduce your bill significantly if you’re on a low income, receiving certain benefits, or you live alone (single person discount is separate and worth checking too).
- Spread payments over 12 months instead of 10 — by law you can ask your council to change from the default 10-month billing cycle to 12 months, which lowers each individual instalment even though the annual total is the same.
- Contact your council early — councils have a legal duty to work with residents struggling to pay, and reaching out before you miss a payment gives you far more options than waiting for a reminder notice or enforcement action.
Worked Examples
Example 1: A Band D household currently paying £2,150 a year is told their council is raising bills by the maximum 4.99%. That’s an increase of £107.29, taking the new annual bill to £2,257.29 — about £188.11 a month over 12 months, or £225.73 a month over 10.
Example 2: A household paying £1,800 a year faces a smaller 2.99% rise (their council skipped the social care precept this year). That adds £53.82, bringing the new bill to £1,853.82 — roughly £154.49 a month over 12 months.
Example 3: A household in a council under financial distress is told their bill is rising 10% with special government permission. On a £2,600 bill, that’s a £260 increase to £2,860 a year — a jump worth checking the council tax support scheme for if it’s a strain.
FAQs
What is the maximum council tax increase allowed in England without a referendum?
Normally 4.99% for councils with adult social care responsibilities (2% core plus up to 2.99% social care precept). Some councils have been given exceptional government permission to exceed this in specific years — check your council’s official announcement to confirm your figure.
Does the council tax cap apply in Scotland and Wales?
No, Scotland and Wales operate under different rules than England and don’t follow the same fixed 4.99% referendum cap, so increases can vary. Check your own council’s announcement for the exact percentage.
Can I pay my council tax over 12 months instead of 10?
Yes. Councils default to 10 monthly instalments (April to January) but must offer 12 monthly instalments if you ask, which lowers each individual payment without changing the total annual amount.
What can I do if I can’t afford my new council tax bill?
Check whether you qualify for your council’s Council Tax Support or Reduction Scheme, ask to spread payments over 12 months, and contact your council directly as early as possible to discuss a payment plan.
Why did my council tax go up by more than 4.99% this year?
A small number of councils facing severe financial pressure have been granted special one-off permission by central government to raise council tax beyond the normal cap without a referendum. This is decided council-by-council, so check your council’s official budget notice for the specific reason.
