Folkert Lútsen Idsinga (Dutch pronunciation:[ˈfɔlkərtˈɪtsɪŋɣaː]; born 22 December 1971) is a Dutch tax lawyer and politician.
He was a partner at law firmBaker McKenzie, and he was elected to theHouse of Representatives in the2021 general election on behalf of the conservative liberalPeople's Party for Freedom and Democracy (VVD). Idsinga left the House in September 2023 to switch toNew Social Contract (NSC), and he wasre-elected in November 2023.

Idsinga was born in 1971 in theFriesland villageBakkeveen and studied fiscal economics at theUniversity of Groningen, graduating in 1996.[2][3] He worked for the accounting firmArthur Andersen until he took a job at the law firmBaker & McKenzie in 2002. Idsinga was specialized invalue-added tax and became apartner in 2004.[4][5] He was promoted to joint managing partner and co-chair of theboard of directors of the company'sAmsterdam office in July 2015.[6] Idsinga stopped being managing partner in 2018 but kept working at Baker McKenzie as a partner.[7][8]
Idsinga ran for member of parliament in the2021 general election as theVVD's 33rd candidate. He was elected, receiving 483preference votes, and was sworn into theHouse of Representatives on 31 March.[9] His portfolio included tax affairs, financial relations between the national government and decentralized governments,export credit insurance and facilities,Holland Casino, the Dutch Lottery, currency, and Domains Movable Property.[10] Idsinga left the House on 5 September 2023. Following hisNovember 2023 re-election on theparty list of NSC, he served as the party's spokesperson for taxation andbenefits.[11]
After thePVV, VVD, NSC, andBBB formed theSchoof cabinet, Idsinga was sworn in as State Secretary for Tax Affairs and the Tax Administration on 2 July 2024.[12][13] His portfolio included taxation, financial relations with lower governments,state ownership ofHolland Casino andNederlandse Loterij [nl], and Domains Movable Property.[14] Idsinga was tasked with steering the 2025 Tax Plan, part of theoverall budget, through the parliament, including theSenate where thegoverning coalition lacked a majority. The plan included asales tax increase on hotel stays, sports, culture, books, and newspapers from 9% to 21%. Opposition parties in the Senate demanded in early October 2024 that this measure would be separated from the Tax Plan, allowing parties to vote differently on the two issues, but Idsinga refused to comply.[15][16]
In October 2024, PVV leaderGeert Wilders joined opposition parties in demanding transparency about Idsinga's retirement savings, which included business interests and could createconflicts of interest. His savings, valued at over €6 million in 2023, were managed by a foundation for the duration of his term, and Idsinga refused to provide more visibility, citing his privacy.[17] TheNOS reported that he was eligible for major tax incentives for a 2019 investment in analgaculture company, which he had disclosed, by categorizing himself as an entrepreneur rather than an investor. Idsinga responded that theTax Administration had ruled that his arrangement was compliant.[18] On 1 November, Idsinga resigned as state secretary, declaring that he perceived a lack of trust from the House. He continued to deny wrongdoing, and he provided an overview of his financial holdings days later as a private citizen.[19] His portfolio included a vacation home, bonds, minority stakes, and shares in mostly foreign companies.[20] Idsinga was succeeded byTjebbe van Oostenbruggen two weeks later, and finance ministerEelco Heinen took over the defense of the 2025 Tax Plan.[16][21]
