Via UKKO.fi, only receipt-based travel costs (for example, travel tickets and accommodation expenses) can be granted tax-free. A breakdown of all reported expenses is also added to the invoice.
Eligible expenses are deducted from the invoiced amount before salary calculation and the corresponding portion is paid without deducting, for example, withholding tax. Expenses against receipts are not salaries, so they will not appear on your invoice. You can check the payments from your account transactions.
Other acquisitions, such as supplies related to the performance of work, can be declared by the light entrepreneur as income acquisition deductions in their personal tax return. The share of expenses should be taken into account when agreeing on the final amount of the invoice. Through UKKO.fi you will receive compensation as a salary, but you can claim a deduction for expenses in your own taxes.
