Council tax bills will rise sharply next year after the government announced plans to increase the annual price cap.

At present, local authorities can hike the tax by up to 2% a year without having to hold a referendum. However, Communities Secretary Sajid Javid revealed this will be rising to 3% for the 2018/19 tax year.

Once you factor in the additional 3% "precept" that many councils are allowed to apply to cover soaring social care costs, it means households are facing hikes of up to 5.99%.

Javid said the increase to the cap would help councils achieve "the independence they need to help relieve pressure on local services".

However, at almost twice the rate of inflation that will be a painful hike for many to absorb, with many household budgets already stretched to the limit.

If there is one crumb of good news for you in all this, it's that you might be living in one of the estimated 400,000 properties that are in the wrong tax band and could be overpaying.

Why your council tax band may be wrong

The amount of council tax you pay in England, Wales and Scotland, is based on the value of your property and the band this puts you in.

Band A properties have the cheapest bills while Band H properties (or Band I in Wales) pay the most to their local council.

The problem is these valuation bands are completely out of date.

In England and Scotland, the bands are based on property valuations made in April 1991 while in Wales they’re based on valuations from April 2003.

Northern Ireland still uses the old system of rates based on rental values, which was replaced across the rest of the UK in 1993. But this is just as bad as they are based on January 2005 prices.

Obviously many things might have happened since 1993, 2003 or 2005 that will have impacted the value of your property like renovations or changes to the surrounding area that means you should be in a different band. 

If you think your council tax band is wrong it’s worth getting it reviewed.

You’ll normally receive a decision from the VOA within two months. It might change your council tax band which will mean your bill will be revised or tell you why your band hasn’t changed.
