Master Money on an Irregular Income

The first nine steps of this course assume a paycheck that repeats. Freelancers, gig workers, contractors, and commission earners live a different reality: a $9,000 March, a $2,500 April, and advice that starts with "take your monthly income" falling flat on its face. This chapter adapts the whole system to income that swings. The principle underneath it: separate what you earn from what you pay yourself.

The baseline month

Pull the last twelve months of income and rank them. Your baseline is what the worst three months say you can count on, not the average: averages are written by your best months and they lie about February. The budget from Step 3 gets rebuilt against the baseline, with essentials fitting inside it. If essentials exceed the baseline, that gap is the first problem to solve: cut the fixed costs or raise the floor with retainer-style work.

The four-account system

• Holding account: every payment lands here first. Nobody spends from it.
• Tax account: 25-30% of every deposit moves here the day it arrives. Untouchable.
• Checking: on the 1st, the holding account pays you a fixed monthly "salary" here. Your budget runs on this number all year.
• Savings and investments: fed by standing rules, not moods (more below).

Big months fatten the holding account; lean months draw it down; your personal budget never feels either. This is pay yourself first with the volatility quarantined upstream.

The buffer: two months of salary

The system runs on the cushion in the holding account. Target two months of your self-paid salary there before loosening anything else; it is the flywheel that turns lumpy income into a smooth one. The buffer is not your emergency fund: Step 4's fund still exists, separately, and irregular earners should lean toward the six-month end of the range, because income risk is precisely the emergency it insures against.

Taxes: the part with deadlines

No employer withholds for you, and the IRS does not wait for April. Two facts organize everything: self-employment tax takes 15.3% of net earnings for Social Security and Medicare before income tax starts, and estimated taxes are due quarterly (April, June, September, January) once you'll owe more than $1,000. The 25-30% slice into the tax account exists so those deadlines are transfers, not crises. Track deductible business expenses as they happen; reconstructing a year of receipts in March is a tax on disorganization.

Retirement without an HR department

Nobody auto-enrolls you, so Step 6's accounts need self-employed replacements, and they are generous:

• SEP IRA: up to 25% of net self-employment earnings, nearly zero paperwork, contributions flex with the year. The simplest start.
• Solo 401(k): employee deferral plus employer contribution; shelters far more at moderate incomes and offers a Roth side. Slightly more setup.
• IRA (traditional or Roth): still available on top, same as anyone (which one, explained).

A workable pattern: a fixed IRA contribution from every salary payment, plus a SEP or solo 401(k) contribution sized once a quarter when the tax picture is clear.

Windfall months get standing orders

Above-baseline money needs rules written in a calm month: top up the buffer, fund the tax account, then split the rest by fixed percentages between goals and lifestyle. Deciding what to do with a fat month during the fat month is how lifestyle creep arrives on an irregular income, and it compounds worse here because the obligations stay when the income dips.

Watch one number

With four accounts and swinging income, the dashboards that matter are the buffer level and your savings rate measured on the salary you actually pay yourself. Stoia shows every account on one screen with rollover budgets and forecasting that stress-tests the slow season in advance. Business bookkeeping proper (invoices, clients, double-entry) is its own discipline; this chapter is about keeping the personal side boring no matter what the business does.
