Sorry for the stupid question, but just to make sure : do you know that iCompta must be opened on the "Synchronization" screen on both devices ? If not they can't see each other.

Ok then it should work, can you tell me what happens now when you try to synchronize ? Does it find the other device ? Or does it show you an error message ?

Which version do you have ? Old versions can not synchronize with local network anymore because Apple enforced new authorization requests to use local network in recent releases of iOS. Only version 6 which is updated can use it.

So this is normal you can't assign a budget inside a scheduler. It will be assigned automatically when occurrences are created in the accounts, or you can assign a budget to a given occurrence in its account.

Are you editing a transaction in the scheduler or a normal transaction in one account ?

Yes you do have to change the status manually. This is because the transfer is frozen after its status has changed and so you have to change the status after all transactions of the month have been entered.

Then you can make a transaction of 4250 with 2 splits :
- first split with amount 5000
- second split with amount -750 and ET amount 0

How much do you really receive on your bank account ? 5000 or 4250 ? When do you have to pay those 750 taxes ?

Amount : 5000
ET Amount: 4250

You should really use the tax field for that purpose. By doing so you will be able to put "Category" then "Taxes" in the "Group by" field of the report and it will give you exactly what you want.
