Council Tax Scotland Change of Circumstances: What to Report and When

Changes You Must Report

Scottish council tax liability can change when your household composition or living arrangements change. If you have been awarded a discount or exemption, the law requires you to notify your council within 21 days of a change that affects your entitlement. Failing to report can lead to backdated bills, penalties, or loss of a discount you're still entitled to.

These are the changes that affect your council tax account:

• Someone moves in or out — a partner, flatmate, or adult child joining or leaving the household can change how many countable adults live at the property. If a counted adult moves into a home receiving the 25% single person discount, the discount ends. If they move out, you may qualify for it.
• A student graduates or drops out — a full-time student who was disregarded becomes a counted adult the day their course officially ends. The gap between finishing a degree in June and graduation in November doesn't matter — the course end date is what counts.
• A care leaver turns 26 — the statutory disregard under SSI 2018/39 runs until the day before their 26th birthday. From that date, they count as a regular adult resident.
• You move house — your liability at each address depends on your status there. Report your move-out and move-in dates to both councils so they can update the accounts.
• A death in the household — the number of counted adults may drop, potentially triggering a single person discount or a dwelling exemption.
• Marriage or separation — a spouse, civil partner, or couple living together as if married moving in can create joint and several liability; a partner moving out may trigger single person discount eligibility from the day they establish a main residence elsewhere.

How to Report

Most Scottish councils accept changes through their online self-service portal (accessed via mygov.scot MyAccount or the council's own website). Look for "Report a change in circumstances" or "Update my council tax" in the council tax section.

If there's no online form, phone or write to the revenues department. Include your council tax reference number, the date the change happened, and what changed. Keep a copy of your letter or a note of your call (date, time, name of the person you spoke to).

Timing Matters

Report changes within 21 days if they affect a discount or exemption you have been awarded. Councils can backdate bills if they discover you should have been paying more — and they regularly run data-matching exercises against electoral rolls, credit reference agencies, and DVLA records to catch unreported changes.

The good news: if a change means you're entitled to a discount you haven't been claiming, councils can also backdate the discount. There's no rigid statutory time limit on backdating in Scotland, though you'll need evidence showing when the change occurred. Utility bills, tenancy agreements, and university certificates all serve as proof.

Moving House: A Common Trip-Up

When you move within Scotland, tell both councils so they can update your accounts. Whether your liability ends at the old address depends on your status there; for example, an owner may remain liable for an empty property. The new council will need your details to bill you and apply any discount.

If you're moving between local authority areas, each council handles its own billing independently. Edinburgh won't notify Glasgow that you've left, and vice versa.
