For the pantograph integro-differential equation (PIDE) with nonhomogeneous term: y'(t) = ay(t)+ ∫01 y(σ(q)t)dµ(q)+ ∫01 y'(ρ(q)t)dv(q)+ f(t), t 0, y(0)= y0, with proportional delays σ(q)t and ρ(q)t, 0 (q), ρ(q) ≤ 1, 0 q m-stage implicit (collocation-based) Runge-Kutta methods at the first mesh point t = h, and give conditions on the collocation polynomials Mm(t) of degree m to u(th), t ∈ [0, 1] such that |u(h)- y(h)| = O(h2m+1), where y(t) is the solution and u(t) is the collocation solution of PIDE. If m = 2 or f(t) is a polynomial of t whose degree is less than or equal to m, then such conditions of Mm(t) are simplified. A numerical example is also included.
