A tax professional who was perfectly adequate before a major life change may not be the right fit afterward. Complexity often enters through events, not through the number of tax forms.
Marriage or divorce
Filing status, withholding, dependents, property ownership, and retirement accounts can change quickly.
Retirement
Social Security, pensions, IRA distributions, Roth conversions, Medicare premiums, and investment income begin interacting.
Inheritance
Inherited IRAs, property basis, trusts, and estate distributions can create new reporting and planning needs.
Relocation
Moving states can create residency and source-income questions.
Business or property transaction
A sale, purchase, or restructuring can justify specialized advice before documents are signed.
