Just for info as this is all sorted now - as a girl who worked in Council Tax I will tell you exactly what happens. It is a government tax and there is legislation surrounding this so it is the same across the country.
If you miss a payment you get a reminder.
If you bring it up to date then all is fine.
If you miss another payment you get a second reminder and this will be the last reminder you would get (only allowed to send 2)
If you do not bring your account up to date after the first reminder OR second reminder or you miss a 3rd payment you are sent a Final notice.
This final notice asks you for the entire balance for the year. At this stage if you cannot pay in full (and let's face it most people couldn't) it then goes to court. Usually no payment arrangement is made at this stage as the only action they can take to recover the money is to write you a letter which obviously isn't working!!
This is a Magistrates Court (not a county court so no CCJ) this is to get them a "liability order" which just says that X is the liable person for that particular bill. Once they have the liability order then you can make a payment arrangement as they then have the power (should you fail to keep your payments up) to deduct the money you owe straight from source (they write to your employer) so your employer takes the money from your salary and pays it to the council on your behalf. They are legally entitled to now ask for your employment details and ask you to fill in a financial questionnaire.
If you are on benefit it will be taken directly from your benefit. If you are self employed/don't work but don't claim benefit then it is passed to the bailiffs. Also if you are a pensioner then they can deduct money from the pension credits.
I really hope this helps everyone out there. It is one of the bills to prioritise if you have financial difficulties as the percentage that they take from your salary is set by central government and is eyewatering!!!!
I am now a sahm, so no shouting please
