Grant applications with overlapping deadlines: listing other grants one has applied for?
This is how I do it and perhaps this could work for you too. Usually I list the applications that I have already submitted and that are under evaluation and I specify the budget size and what the funding will be used for (PhDs, postoc, own salary) and in particular I specify for for each of them if it is related or not to the current application. I also mention somewhere what is the priority, e.g. that if both the current application and one of those that I have applied for already -and that is on the same topic - will be funded, then one of the two (usually the smaller in terms of budget or prestige) will be not be maintained or will be withdrawn. It's a bit difficult to list applications that you plan to do but haven't written yet, because in principle you might not manage to submit them. So usually I avoid doing that unless I am 100% sure I will submit it. I also think it's pretty normal to submit similar project ideas to different councils and in different formats, and this simply shows that you are active in the hard job of fund raising so for me is a positive sign. In general it's always good to be transparent when it comes to applications.
