脱退一時金の請求＆所得税の還付申告　Lump-sum Withdrawal & Tax Refund Support in Japan

東京国税局に15年間勤務し、源泉所得税の専門部署で非居住者への課税・租税条約の適用・国際源泉の実務を担当してきました。

また、街角の年金相談センターで年金相談員として勤務しており、年金制度の実務にも日常的に携わっています。

脱退一時金は、年金相談の中で存在を知り、税務と年金の両方にまたがるこの手続きに興味があります。

税金側（源泉徴収・租税条約・還付申告）は税理士として対応し、年金側（請求手続き）は社会保険労務士として対応します。

あちこち相談しなくていい。

年金も税金もこちらで完結します。

I spent 15 years at the Tokyo Regional Taxation Bureau,specializing in withholding income tax

— including taxation of non-residents and the application of tax treaties.

I also work as a pension consultant at a local pension consultation center,
where I handle pension-related inquiries on a regular basis.

Through that work, I came across the lump-sum withdrawal system —
a procedure that caught my interest, sitting at the intersection of pension and tax.

The tax side (withholding, tax treaties, refund filing) is handled in my capacity as a Certified Tax Accountant.

The pension side (withdrawal application) is handled  as a Social Insurance Consultant.

No need to consult multiple professionals.

Pension and tax — both handled here.
