Freelancer & small business finance
Self-employment moves the tax, banking, and borrowing decisions an employer used to handle onto you. This hub collects what SwitchWize has built for exactly that: quarterly tax planning, freelancer- and small-business-specific banking, SBA and other loans, business credit cards, and retirement accounts built for people without an employer plan.
How this hub is built
This is a curated map of existing SwitchWize coverage, not bookkeeping or accounting software -- if you're looking for invoicing, payroll, or P&L templates, that's a different product category and not something covered here. Every article and calculator linked below is scoped to a specific decision (which bank, which loan type, which retirement account, how much tax to set aside), verified live before publishing, and organized by the decision it helps you make rather than dumped into one undifferentiated list.

The Self-Employed Money Playbook: Taxes to Retirement (2026)
When you work for yourself, no employer withholds your taxes, funds your retirement, or subsidizes your health plan. You build all of it, and the freelancers who thrive treat it as four systems. This is the complete playbook: the 15.3% self-employment tax and quarterly payments, the retirement accounts that let you shelter far more than an employee can, irregular-income cash flow, and benefits.
Self-Employed Taxes Explained: What You Owe and How to Pay
Self-employed workers pay self-employment tax (Social Security + Medicare) plus income tax, and must send quarterly estimated payments or face penalties. Here's the full picture for freelancers, contractors, and sole proprietors.

Frequently asked questions
How much should I set aside for self-employment tax?
A common starting point is 25-30% of net profit for federal self-employment and income tax combined, though the precise self-employment tax itself is 15.3% of 92.35% of net profit (Social Security up to the annual wage base, plus Medicare with no cap). The exact share depends on your total income, filing status, and deductions -- use the Self-Employment Tax and Quarterly Estimated Tax calculators below with your real numbers rather than a flat rule of thumb.
What's the actual difference between a freelancer bank account and a small business bank account?
Freelancer-focused accounts (Found, Lili, and similar) typically bundle tax set-aside automation and light bookkeeping for a single earner with irregular, multi-platform income. Small-business accounts (Bluevine, Mercury, Relay, and traditional business checking) are built for higher transaction volume, sub-account cash management, and eventual hiring or incorporation. A solo freelancer with simple income usually gets more value from the freelancer-specific tools; a small business with payroll or multiple revenue streams usually outgrows them.
Should I get an SBA loan or a regular small business loan?
SBA loans (7(a), 504, microloans, and Express) carry a government guarantee that lets banks offer lower rates and longer terms than they would on their own, which usually makes them cheaper if you qualify and can wait through a longer approval process. A conventional or online small-business loan is faster to close but typically costs more. The right choice depends mostly on how urgently you need the funds versus how much the rate difference matters over the loan term.
SEP IRA or solo 401(k) for a self-employed retirement account?
A solo 401(k) generally allows higher contributions at the same income level because it lets you contribute as both employee and employer, and it supports a Roth option that a SEP IRA does not. A SEP IRA is simpler to set up and administer if you don't need the extra contribution room or Roth access. Compare your specific numbers with the SEP IRA vs Solo 401(k) calculator below.
Do I need a separate business bank account if I'm a sole proprietor with no LLC?
It's not legally required for a sole proprietorship the way it is for an LLC or corporation, but mixing business and personal transactions makes tax time significantly harder and weakens your records if you're ever audited. Most of the banking guides in this hub recommend a separate account regardless of entity type, purely for the bookkeeping and tax-prep time it saves.
