I'm glad to answer your question, how much can you write a monthly invoice for drinking? The actual tax-free,? How many invoices can a self-employed person open for free each month? The following from April 1, 2021 onwards the state regulations of the individual tax-free monthly invoices can be opened 150,000, quarterly invoices can be opened 450,000. The monthly tax exemption for small-scale taxpayers is 150,000 yuan, and the quarterly tax exemption is 450,000 yuan. So small-scale taxpayers can issue 150,000 tax-free invoices per month. More than quarterly 450,000, according to the full amount of tax, VAT invoice tax according to the actual occurrence of payment, not tax-free, single will account for the amount of tax exemption. Individuals can be free to issue 100,000 yuan per month, or quarterly, if you can have 300,000 yuan of tax-free credit per quarter.
