Hi, I am looking for some advice on how the taxation in Geneva works.

My husband was only employed for 80% of the time in 2007 and i paid tax at source with tax rate A for the whole year. My husband did not pay any tax as his employer pays him a different amount each month and told him it would be easier to add it up at year end.

So we sent in a letter to have my tax modified (knowing i paid tax rate A for the whole year but he wasn't working) and to tell us how much tax my husband owed. Now they have sent us a bill for 7000 francs saying he needs to pay almost 24% of his salary of only 38K! (they gave me a small refund of 1500 francs).

So how does this work? it seems as though they have added both of our salaries together and charged us a tax rate as though we earn over 200K! it doesn't make sense as i paid an extra 500 francs a month just because he was working and now they also tax him at one of the highest rates?
