First-Year Independence Roadmap: Six Months Before and After Going Freelance

This article is general information for those considering independence, not tax or legal advice. For specific tax, contract, or insurance decisions, consult a licensed tax accountant, attorney, or social insurance labor consultant. Numbers and rules reflect the time of writing; verify current rules with the relevant government authorities.

This article is written for those in job categories that accumulate monthly small-to-mid recurring engagements, such as web designers, writers, and graphic designers. Engineers, video producers, or consultants with different project scales and payment cycles may experience different numbers.

"I want to go independent as a web designer." "I want to switch from a full-time job to freelance writing." "My side work is picking up, so I'm ready to quit." We hear stories like this every month, but the share of people still earning stably one year later is far from high. The main cause of failure isn't poor sales skills after independence — it's inadequate preparation in the six months before.

Tax Preparation (Three to Six Months Before Independence)

The first thing to tackle is understanding taxes. Learn the difference between blue-form filing and white-form filing, the scope of deductible expenses, and look at the opening-declaration forms published by the National Tax Agency before you actually need them. Start using one of the main accounting apps (freee, Money Forward, Yayoi) during your side-work period so that you can shift straight into full-time bookkeeping on day one.

B2B invoicing has a cycle in which the previous month's sales arrive in your account one to two months later. You must experience this rhythm during side-work by actually issuing invoices and collecting payments. Going independent with the mental model of a cash-register business leaves you unable to bridge the two-to-three-month gap before money starts flowing.

Contract Templates (Two to Four Months Before Independence)

Finish your four core templates before going independent: service agreement, NDA, estimate, and invoice. You don't have to start from scratch — adapt contract templates published by the Small and Medium Enterprise Agency or industry bodies, or use the templates we distribute under /templates, customized for your type of work.

Going independent without templates leads to "let's just agree by email for this first project," which sows the seeds for later disputes over payments, scope creep, and copyright.

Pipeline Building (One to Three Months Before Independence)

Most important of all: hold at least one recurring engagement worth ¥50,000+ per month before you go full time. If you go independent with only one-off projects, the first two or three months are consumed by sales activity, and your core work never starts.

Creating recurring work is simple: to a client who was happy with a one-off project, propose "I can take on ongoing maintenance up to X hours per month for ¥X." The Cabinet Secretariat's freelance survey likewise shows that many freelancers depend on a small number of recurring clients, and the presence or absence of such work determines whether your business is sustainable.

The "one-client concentration to secure recurring work" before independence and the "avoid single-client dependence" principle after independence are not contradictory if you view them in time sequence. Spend the six months before independence making one recurring relationship concrete, then move toward a two- or three-client setup in the first one to three months after independence. A slow transition here feeds directly into Pattern 2 (single-client dependence) below.

Cash Reserves (Zero to Six Months Before Independence)

A hidden trap is the two-step burden of resident tax and national health insurance in year two. In your first year of independence, you are billed resident tax and insurance based on your employment income. In year two, you are billed based on your first-year self-employment income, and resident tax (billed from June, in installments), national health insurance (in multiple installments), income tax (March or prepayments), and individual enterprise tax (for applicable filers) arrive at different times. If your first-year profit is high, year-two fixed costs (resident tax and NHI) jump significantly, so cash flow must be planned a year ahead from the start. See also First-Year Tax Return Guide.

Mandatory Filings in the First Month

Complete these within one month of independence:

1. Switch national health insurance and national pension at your municipal office within 14 days of employment ending (tightest deadline)
2. Activate your business account and route all sales and expenses through it
3. File the opening declaration at the tax office (via e-Tax, about 30 minutes, within one month)
4. File the blue-form approval request within two months of opening — forget this and you are stuck with white-form in year one
5. Consider joining the Small Enterprise Mutual Aid scheme — contributions qualify as deductible. Review the scheme details before joining. See Insurance, Pension, and Mutual Aid for Freelancers for comparison.

Workload Pacing for the First Three Months

In the first three months, spend 90% of your time "reliably delivering existing projects." New sales can wait — they should take only 10% of your time. By executing the work you lined up before independence, you accumulate two essential assets: a delivery track record and a payment history. Without both, new-client pitches from month four onward lack credibility.

Measuring Retention

From month four, track retention as a concrete number: the share of clients from whom you received a follow-up engagement. Aim for 40% or higher by month six. If retention is low, you are missing opportunities at delivery — lacking structured wrap-up conversations, follow-up reports, or proactive next-project proposals.

Timing Price Reviews

In year one, it is realistic to price slightly below market since you lack track record. Once you have enough delivered projects and stable recurring clients by month six, review new-client prices in measured steps. Hold existing recurring clients at the same rate through year one and revise gradually from year two. See Freelance Pricing Strategies for detail on setting rates.

Pattern 1: Cash Flow Collapse

Running out of cash at month three or four due to the "incoming lag." Avoided by having six months of reserves set aside in advance.

Pattern 2: Single-Client Dependence

Winning a large project immediately after independence and pouring all resources into it. Income drops to zero the moment the relationship ends. Avoid heavy concentration on any single client and consciously spread revenue across multiple clients. Japan's Subcontracting Act and Freelance Protection Act also regulate abuse of superior bargaining positions, so concentration creates legal risk on top of commercial risk.

Pattern 3: Tax Surprise

In year one's filing, the confirmed tax bill exceeds what you expected and requires installment payments. Starting from month one, set aside a portion of each sales payment into a separate account based on estimated annual tax and social insurance obligations. The appropriate ratio varies with income, industry, and deductions — consult a tax accountant if needed.

Pattern 4: Isolation-Induced Decision Fatigue

Without colleagues to talk to, the stress of making every business decision alone damages your health. Deliberately build consultation channels through Freelance Association communities and monthly check-ins with senior freelancers in your field.

Wait until all five items are checked before handing in your notice. Missing any one forces you to spend your first six months after independence catching up, leaving no time for actual business development.
