Filing as married filing jointly on $120K (single earner) saves you $7,585/year ($632/month) compared to filing single. This marriage bonus comes from the doubled standard deduction ($32,200 vs $16,100) and wider lower brackets.
Software engineers frequently receive compensation in the form of restricted stock units (RSUs) and stock options. When RSUs vest, they’re taxed as ordinary income at your marginal rate, which can push you into a higher bracket during vest years. If you exercise incentive stock options (ISOs), the spread between strike and market price may trigger Alternative Minimum Tax (AMT). Consider spreading option exercises across multiple tax years to minimize bracket creep. Many engineers also benefit from the home office deduction if working remotely.
