Review the new tax laws. The Tax Cuts and Jobs Act, which passed in late 2017, introduced some major changes that could affect your year-end tax strategies. The standard deduction has doubled, making itemized deductions less attractive. Depending on your situation, you might take itemized deductions every other year and decide to bunch two years of charitable donations together to make best use of itemizing. Consult with your accountant or tax preparer on how to take advantage of opportunities created by the new tax rules.
