## Introduction: Two Ways to Calculate Your Consumption Tax

Since Japan's Invoice System (インボイス制度) took effect in October 2023, many freelancers and sole proprietors became consumption tax (*shohizei*) payers for the first time. That immediately raises a practical question: do you calculate your actual input tax on every purchase (standard method), or use a simplified flat-rate approach (*kanizei*)?

The right answer depends on your industry and expense level. This guide breaks down the simplified consumption tax system in plain English so you can make an informed choice.

## What Is the Simplified Consumption Tax System (簡易課税制度)?

Under Japan's standard consumption tax rules, you deduct the consumption tax you paid on purchases (*shiire zei*) from the consumption tax you collected on sales (*uriage zei*), and remit the difference to the NTA.

The simplified system replaces the actual input calculation with a **deemed purchase rate (みなし仕入率)** — a fixed percentage applied to your sales-side consumption tax to determine how much you can deduct. The result is a simpler calculation requiring less bookkeeping.

## Eligibility Requirements

- **Taxable sales ≤ ¥50 million** in the base period (the fiscal year two years prior).
- **Advance registration required**: You must file the "Simplified Tax System Election Notice" (消費税簡易課税制度選択届出書) with your local tax office *before* the start of the tax year you want to apply it — typically by December 31 of the prior year.

## Deemed Purchase Rates by Industry

- **Type 1 — Wholesale**: 90%
- **Type 2 — Retail / Agriculture-Fishery (certain)**: 80%
- **Type 3 — Manufacturing / Construction**: 70%
- **Type 4 — Food & Beverage / Other**: 60%
- **Type 5 — Services (freelance, consulting, IT, finance, insurance)**: 50%
- **Type 6 — Real Estate**: 40%

Most freelancers (designers, engineers, writers, consultants) fall under **Type 5 at 50%**.

## Worked Example: Freelance Engineer

Annual taxable sales: ¥8,000,000 (¥8,800,000 including 10% consumption tax).

### Simplified Method (Type 5 — 50% deemed rate)

- Consumption tax collected: ¥8,800,000 ÷ 1.1 × 10% = **¥800,000**
- Deemed deductible: ¥800,000 × 50% = **¥400,000**
- **Tax payable: ¥400,000**

### Standard Method (actual expenses include ¥200,000 in consumption tax paid)

- Consumption tax collected: **¥800,000**
- Actual deductible: **¥200,000**
- **Tax payable: ¥600,000**

In this scenario, the simplified method saves ¥200,000. But if your actual deductible input tax exceeds ¥400,000 (e.g., you bought expensive equipment), the standard method becomes cheaper.

## The 2-Year Lock-In Rule

Once elected, you must use the simplified system for **at least two consecutive years**. You cannot switch mid-year. Plan around major equipment purchases before electing.

## Invoice System Interaction

Under the Invoice System, simplified-method taxpayers still must *retain* qualified invoices they receive, but they do not need to itemize input tax from each one — the deemed rate handles that globally. This makes receipt management less intensive than standard-method filing.

Tools like [Denpyo](https://denpyo.com/) can auto-extract receipt data from photos to meet Japan's Electronic Bookkeeping Law storage requirements regardless of which method you use.

## Should You Choose Simplified? A Quick Checklist

Lean toward simplified if: you are a service-industry freelancer (Type 5), your expenses are less than ~40% of revenue, and you want simpler bookkeeping. Lean toward standard if: you plan large equipment purchases, your subcontracting costs are high, or your actual input tax would exceed the deemed deduction.

## How to Register

Submit the "Simplified Tax System Election Notice" to your local tax office or via e-Tax before December 31 for the following year's application. The form is available on the [NTA website](https://www.nta.go.jp/). Our free [Tax Savings Estimator](https://denpyo.com/tools/tax-savings-estimator) can help you model the difference before deciding.

## Summary

Japan's simplified consumption tax system is a powerful tool for small service-based freelancers and SMEs. The deemed 50% deduction rate often results in lower taxes than tracking actual expenses — but the 2-year lock-in means you should model future expense levels carefully before electing. When in doubt, consult a *zeirishi* (licensed tax accountant).
