Tax Tools Built for the Self-Employed — Without the Sales Pitch
Being your own boss means being your own payroll department, tax planner, and CFO. The hardest part is rarely the work itself — it is the 15.3% self-employment tax, the quarterly estimated payments, and the constant question of whether forming an S-corp would actually save you money. Most calculators that promise to answer these questions are run by companies selling the very service they are calculating for, so their math quietly favors "yes, hire us."
These tools are different: independent, transparent, and free. They run entirely in your browser, store nothing, and show you the full picture — including the costs the sales-funnel calculators leave out.
LLC vs S-Corp: The Honest Version
An S-corp election can lower your self-employment tax by letting you split your income into a "reasonable salary" (subject to payroll tax) and distributions (not subject to it). But it also adds real costs: payroll software, a higher tax-prep bill, and state-level S-corp fees. Many online calculators show only the tax savings and hide the costs. Our LLC vs S-Corp Calculator nets them out, so you see your actual savings — and it will tell you honestly when staying a default LLC is the smarter move.
Understanding 1099 and Quarterly Taxes
As a 1099 contractor, no employer withholds taxes for you. You owe both halves of Social Security and Medicare (the 15.3% self-employment tax) plus federal income tax — and the IRS expects you to pay it in four quarterly installments rather than once a year. Our 1099 Tax & Quarterly Estimator calculates your self-employment tax, applies the half-SE and QBI deductions, and divides your total into four estimated payments due April 15, June 15, September 15, and January 15.
When Does an S-Corp Make Sense?
A common rule of thumb is that an S-corp starts to pay off once your net business profit reliably exceeds roughly $80,000 per year — enough that the self-employment tax savings clear the added payroll and accounting costs. Below that, the costs often eat the savings. But the threshold depends on your state, your reasonable salary, and how steady your income is. Run your real numbers through the calculator and confirm with a CPA before electing S-corp status.
