National tax: It is necessary to cancel the existing anti-counterfeiting and tax-controlled invoicing system in Dongcheng, sort out all invoices, hand in unused invoices, check used invoices, check lost invoices, check taxes and provide other tax information. Transferring to the district requires field visits, which is not much different from the new office. It will take about three months to invoice. I've dealt with it before.
Local tax: tax checking is relatively simple.
Please consult the supervisor for specific matters.
