Many people do last-minute tax planning at the end of the year.
I consulted a specialist about tax reduction strategies for saving on taxes.
節税 specifically means 'tax saving' and often refers to the result or act of reducing taxes, while 税金対策 is broader, encompassing planning and strategies.
脱税 means 'tax evasion', which is illegal, whereas 税金対策 generally implies legal tax avoidance or planning.
Compound of 税金 (tax) and 対策 (countermeasure, strategy).
