Filing as married filing jointly on $80K (single earner) saves you $3,585/year ($299/month) compared to filing single. This marriage bonus comes from the doubled standard deduction ($32,200 vs $16,100) and wider lower brackets.
Data scientists often receive significant equity compensation, especially at tech companies. RSU vesting creates lumpy income that can push you into higher brackets in certain years. Conference speaking fees and consulting income on the side are common in this field and must be reported as self-employment income. If you publish research or create open-source tools, any related expenses may be deductible as unreimbursed business expenses. Consider tax-loss harvesting on personal investments to offset gains from equity compensation.
