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.
Web developers who freelance or do contract work alongside a full-time role need to plan for self-employment tax (15.3%) on that side income. Even small freelance projects can trigger estimated quarterly tax payments. If you work remotely, be mindful of nexus rules — some states tax income based on where the work is performed, not where the company is headquartered. Consider setting up an S-Corp if your freelance income exceeds $40K to potentially reduce self-employment taxes.
