Kristoffer Ajer Net Worth

Kristoffer Vassbakk Köpp Ajer is a Norwegian professional footballer who plays as a centre-back or right-back for Premier League club Brentford and the Norway national team. He was born in Rælingen on 17 April 1998 and moved to Kristiansand as a teenager when his parents relocated there.

Norway's official tax list for the 2024 income year records his net wealth at NOK 7.0 million, about $0.75 million at the November 6, 2026 exchange rate. TV 2 printed the figure on December 3, 2025 in its tables of Norway's biggest sports names, alongside taxable income of NOK 192,396.

What the tax list shows

TV 2's table for income year 2024 lists Ajer with income NOK 192,396 and net wealth NOK 7,031,351, registered in Kristiansand S. The list figures come straight from the Norwegian Tax Administration, which publishes every taxpayer's income, wealth and tax each year. His Norwegian taxable income was only NOK 192,396, because, as TV 2 noted, players paid abroad usually pay most of their tax in the country where they play.

Net wealth on the list is assets minus debts at tax values. Homes are counted well below market price and shares at a discount, and money held through a holding company appears only through the value of its shares.

About this figure

Norway publishes every taxpayer's income, net wealth and tax paid each year, and newspapers comb the lists for famous names. TV 2 printed Ajer's figures for the 2024 income year. Net wealth on the list is the figure the Tax Administration assessed from his tax return, assets minus debts.

Tax values are lower than market values, especially for homes and shares, so the figure understates what Ajer would be worth if everything were sold. We show it in Norwegian kroner, as published, with a rough US dollar conversion at the November 6, 2026 exchange rate. Income figures mentioned on this page are earnings for one year, not wealth.
