Who should pay the council tax?

It doesn't matter that it's a new bill, all the household bills go into the same mix. I think it would be reasonable for person A to be paying more into a joint bills account but I can't advise what that split should be without knowing what person B's total income is (regardless of whether it's from benefits or not).

Person A and person B are not financially compatible.

The council tax should be included in the bills that are going to be split 50/50.

The person moving in without children would still be subsidising the child, even though the parent refuses to see that.

How much will person B be receiving in all benefits after the £800 reduction - including the child maintenance payments too?

Even though person B will have their income reduced if they are receiving more/the same/similar to what person A is earning I would just split the cost between the two.

I think @Cavapoo123 needs to be more transparent on what her income is for this to be accurately assessed as such.

The reason the council tax is different is because they previously weren’t paying it.

So agreeing to split existing bills I suppose is easy enough to agree on - but the council tax is a ‘new’ bill.

Each person should gain or lose the same amount of money compared to their prior situation. It sounds like B will be losing a total of 1000 (800 in benefits that B will no longer receive, and 200 in council tax that B now has to pay) whereas A will be gaining 800. That's not fair to B. Actually B will lose more than A will gain so to me it sounds like this move is unaffordable.

If person B is moving in as a lodger separate food bills et cetera would be okay if person B is moving in to be part of a family all household bills need to be shared
if person B is moving in to be part of a couple that won’t work as a child is not an independent personI would suggest all income from whatever source into one joint account ends monthly direct debits to each of you for personal expenses say £300 each.

How much do you get in total @Cavapoo123 why did you leave that information out?

Should be shared as should all bills.

The only 100% disability exemption for CT is severe mental impairment. And the OP says this is not the case.
Can get a reduction if have extra rooms or bathrooms due to disability which puts the CT into a higher band

Sounds like this isn't going to work. In any case if person A is responsibke for the council tax they need to pay it all. Why should either person be out of pocket.

If I were person B, I'd not move person A in unless the other person contributed more to the cost of the house. £750 is quite low, esp around SE England.

And if person A does not wfh and person b is at home running up the electricity bill etc?

Why does it all come down to council tax? There are a whole host of household bills and responsibilities that need to be discussed surely?

I'm assuming A&B are in a romantic relationship and this is them moving in together as partners.

Why don't A&B have a joint account from which all the household bills are paid. Both pay into it but the percentages of who pays what is dependent on income. This is what my husband and I did when I went on maternity leave then worked part time while the children were younger. It's changed as I've worked more days and earned more.

Your question is "who is responsible for the council tax payment". The whole household is responsible so it comes out of that joint account.

What you've not mentioned is how much income you have from the disability benefits other than it decreasing by £800 post move. That's all I'd need to make a sensible suggestion for who pays what into that joint account, even without knowing how much the household bills come to.

I'd also add that the child maintenance B receives doesn't sound like much compared to what my husband used to pay for his daughter.

A is gaining 800 quid a month , B is losing 100 quid a month.

A should pay. The financial impact is already too great on B and actually I think A should be contributing a bit more so they're both balanced.

It might just be me but it would have been easier to say my partner or me instead of the person a and person b stuff, unless that is your names in which case 😳

I was literally just going to ask this?!

The person moving in will also be a person responsible for paying the council tax according to the local authority. So if the original resident doesn't pay then the other party can be persued for the debt. Regarding the bills, those should be paid proportionately according to the income of each person. If you aren't happy with that, don't move in.

Person B should NOT put someone on the tenancy agreement as that could effectively make them homeless in future.
Persons A and B should both be equally better off as a result of moving in.

So work out everyone’s costs beforehand.
Work out the costs together.
Split the difference.

The DC won’t be using significant amounts of electricity and water, given that person B plans to cover her DCs food and day to day expenses separately.
Person A may use more than person B, depending on their wfh and eating habits. People tend to be less careful when someone is splitting the bill with them.

Your primary responsibility is your child, assuming you’re person B op. Why on earth are you moving someone in when it will have such a huge hit on your finances and risk your security? It’s madness.

Until it's all discussed and decided then no one should be moving in with anyone else.

Agree with this, just split it. Also I’d imagine your benefits would be higher than person A’s wage?

Would advise not to put them on the tenancy until you know it will work out. You can still declare them without them being a tenant.
I would suggest that A quibbling about paying council tax while B is losing so much income shows this isn't going to last the long haul.

Unless finances are going to be completely joint, I don’t think you should move in together. The main point is that person A will be better off and person B worse off and that isn’t fair.

Does person B’s ex contribute toward their child at all? Either way, you need to keep living apart and just spend weekends together.
