Filing as married filing jointly on $100K (single earner) saves you $5,585/year ($465/month) compared to filing single. This marriage bonus comes from the doubled standard deduction ($32,200 vs $16,100) and wider lower brackets.
Project managers with PMP or other professional certifications can often have these costs reimbursed tax-free through employer professional development programs. If you do independent consulting between roles, that 1099 income is subject to self-employment tax at 15.3%. Travel-heavy PM roles may generate per diem income that’s tax-free if within IRS limits. Consider maximizing pre-tax retirement contributions to offset the impact of any bonus or overtime income that pushes you into a higher bracket.
