What you need to know
At $150,000, tax planning is not an advanced hobby anymore; it is part of running the business correctly. The combination of 24% federal rates, self-employment tax, and state tax can push the all-in burden close to 30% or slightly above, so even a few bad assumptions have a big dollar impact. A freelancer who wings it at this level can easily create a $10,000 problem without doing anything dramatic.
This is the range where large retirement contributions and entity optimization can materially change take-home pay. A strong Solo 401(k) contribution, clean expense tracking, and a properly run S-Corp can shift thousands of dollars a year, but only if payroll, bookkeeping, and distributions are handled correctly. The planning cost is higher than at $50,000, but the savings are also large enough to justify adult-level systems.
Cash management has to keep up with the bigger numbers. Quarterly estimates can easily land around $10,000-$12,000 each before state tax adjustments, which means your tax reserve account needs to be genuinely funded rather than symbolically funded. When income is lumpy, many freelancers in this band review estimates after every large project instead of waiting for the next calendar quarter.
