I have an external collaborator on the project who will incur a lot of travel costs (which will be recorded in detail). The subcontract we will conclude dictates that travel costs will be charged. This reduces my project funds, which are already very scarce in relation to the work expected. The travel expenses can be claimed a year later on income tax. However, this seems to me to be pointless - extra work for the contractor and the FURS, when everything will be clearly documented from day one. Why is that? Is it really not possible to reimburse them as employees are reimbursed - a simple reimbursement on the basis of evidence?
