Theory — what are deductible costs in a contract for specific work?
A contract for specific work is a civil-law agreement where standard tax-deductible costs equal 20% of income. A higher 50% rate applies only to qualified copyright income and up to an annual statutory limit. The calculator computes net pay under both cost options and shows how the PIT advance payment affects the result. Labeling an agreement a specific-work contract alone does not qualify it for the higher rate — the nature of the work performed decides.
