Council Tax Six Month Rule Scotland: Deadline for Band Challenges

The Six-Month Window

Under Regulation 5(5) of the Council Tax (Alteration of Lists and Appeals) (Scotland) Regulations 1993, anyone who becomes a new taxpayer for a property has exactly six months to submit a formal proposal to challenge the council tax band.

The clock starts on the date you become liable — typically the settlement date when buying, or the tenancy start date when renting. Not the date you moved in physically, not the date you received your first bill, not the date you noticed the band looked wrong. The statutory trigger is when liability transfers to you.

This is the most important deadline in Scottish council tax band challenges. Miss it, and you lose the right to challenge your band on general grounds.

Who Gets the Six-Month Window

The window applies to anyone newly assuming council tax liability:

• Buyers — six months from the date they become liable (often the settlement date)
• New tenants — six months from the date their liability starts (often the tenancy start date, where the tenant is liable)
• Surviving partners or family members who become liable after a death
• Anyone inheriting liability through a change in household circumstances

Former taxpayers can submit a proposal covering their own period of liability, subject to the applicable statutory grounds and time limits. Moving out does not restart the six-month clock.

What Happens If You Miss It

If you submit a proposal outside the six-month window without a qualifying statutory trigger, the Assessor will issue an Invalidity Notice under Regulations 8 or 9. This is a formal rejection saying your proposal doesn't meet the requirements.

You can appeal an Invalidity Notice to the Local Taxation Chamber using Form C-4a within 28 days of receiving it — but these appeals are decided on written representations only, and the tribunal will uphold the Assessor's notice if you genuinely lack standing.

Exceptions: When Long-Term Residents Can Challenge

The six-month rule doesn't mean long-term homeowners can never challenge their band. Specific statutory triggers can create a new proposal window, with the deadline depending on the trigger:

• Material reduction in value — partial demolition, qualifying physical changes in the locality (e.g., a major industrial development or severe structural nuisance), or an adaptation for a disabled resident.
• Assessor-initiated alteration — if the Assessor changes the list entry on their own, you get six months from the date of their alteration notice.
• Relevant court or tribunal decision — if a decision alters another property's band and establishes a relevant precedent, a six-month proposal window may apply from the decision.

General market conditions don't count. A fall in house prices across Scotland, or a feeling that your band is "unfair" compared to a neighbour's, doesn't create standing outside the six-month window.

Practical Tips

Track the exact date. Your liability start date is on your first council tax demand notice. Keep a copy — if the Assessor challenges your standing, you need to prove you filed within six months.

Don't confuse enquiries with proposals. Phoning the Assessor's office to ask about your band doesn't pause or preserve the deadline. Only a formal written proposal (through the SAA portal, email, or post) counts.

Submit early, not late. If you're close to the deadline and still gathering evidence, submit a complete proposal on time; you can provide additional evidence during the Assessor's review. Omitting required information can lead to an Invalidity Notice.

Tenants have standing too. A persistent myth says only property owners can challenge. If you're the liable taxpayer, you have the same right to submit a proposal as any homeowner.
