Wilson turned 20 the month before signing for Gary Naysmith and QoS on loan from Kilmarnock on 29 January 2019. The Scottish FA website list him with 5 caps for Scotland at u17, 4 at u19, 5 at u20 and 6 at u21 level at time of joining. His Scotland u21 debut was the 2-0 victory in Paisley against Netherlands on 5 September 2018 when Oliver Burke and Stevie Mallan Jr scored. He then played in the 2018 Toulon tournament as Scotland drew 1-1 with Togo with Everton's Fraser Hornby scoring for Scotland, Burke scored when defeating host nation France 1-0, and then defeating South Korea 2-1 with Burke and Chelsea's Billy Gilmour hitting Scottish goals. Scotland ended top of their group. In the semi-final they led 1-0 at half time against England through a Mikey Johnston goal. Wilson was subbed at half-time before Arsenal's Eddie Nketiah inspired England with 2 goals and an assist to come from behind to win 3-1. Scotland lost the third place play-off to Turkey on penalties after drawing 0-0. Wilson played in all 5 Scottish games at Toulon 2018.

He is described on the Scottish FA website as, "The type of player coaches and team-mates love. A quiet, unassuming character, he changes completely when he steps over that white line and his midfield firefighting alongside Motherwell’s Allan Campbell has been a key factor in the success of Scotland’s Under-21s this summer at the prestigious Toulon tournament."

At time of joining Wilson had 48 first team appearance for Kilmarnock including 39 in the top division. Another versatile player as per what Naysmith seems to favour. In Wilson's case he plays at either centre-midfield or centre-back. He has also covered at right back for Killie. His solitary senior goal so far in his Killie career up 'til signing for QoS was an 87th minute winner defeating Dundee 3-2 at home on Tuesday 13 February 2018. He is highly regarded by Steve Clarke and Scot Gemmill (Killie and Scotland u21 managers respectfully at time of Wilson joining QoS).

His QoS debut was on 2 February 2019. This was in the 3-0 defeat at Falkirk. While at QoS he played for Scotland under 21s in Marbella on Monday 25 March 2019 in a friendly v Sweden. Wilson's QoS team mate, Barry Maguire on loan from Motherwell, scored in under a minute for the Scots in a 2-1 defeat.

His first QoS goal was the 44th minute opener in the 2-1 home league win v Dunfermline on Saturday 20 April 2019. As well as that right foot strike low into the corner of the net, his energetic, forceful, midfield box to box contribution earned him man of the match in that game.

Iain Wilson played 18 competitive first team QoS games comprising 14 in the league and 4 in the end of season play-offs that successfully preserved QoS' status in the Scottish professional football second tier. His last QoS game of his loan at the club was the 0-0 home draw v Raith Rovers on 18 May 2019 for an aggregate 3-1 play-off win. He departed with one goal in the scoring chart; the strike mentioned above v Dunfermline.

Aged 21, Wilson was announced on 31 January 2020 as re-signed for QoS this time by Allan Johnston . This was again on loan from Kilmarnock until the end of the season. In his time back at Kilmarnock he had added 4 1st team competitive appearances to his name (3 starts and 1 as a late sub all in the league top tier).

His 1st game on his QoS return was on Saturday 1 February 2020 in the 3-2 home league defeat by Dunfermline. Wilson played at centre-back in that game in which QoS had 4 1st team players out injured.
