class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Under the Value Added Tax Act, the basic VAT rate is 101 TP3 T. However, that is not the end of it. Only after subtracting the tax paid on purchases during the first half of the year (input tax) from the tax received on sales during the first half of the year (output tax) do we finally arrive at... <strong>The actual tax to be paid is determined.<\/strong>.<\/p>\n<p>For example, if you are a business owner operating a cafe, you have received VAT from customers (approximately 5,000,000 won based on sales of 55,000,000 won), while you have also paid VAT when purchasing items such as coffee beans or milk (approximately 3,000,000 won based on 33,000,000 won). If you subtract these two, the basic tax payable becomes 2,000,000 won.<\/p>\n<blockquote><p>What the VAT calculator can do: Separating the price of a single transaction \/ What the VAT calculator cannot do: The final payable amount considering deductions for the entire reporting period<\/p><\/blockquote>\n<h2><span class=\"ez-toc-section\" id=\"%ED%95%9C_%EA%B1%B0%EB%9E%98%EC%97%90%EC%84%9C_%EB%B6%80%EA%B0%80%EC%84%B8_%ED%8F%AC%ED%95%A8_%EA%B8%88%EC%95%A1%EC%9D%84_%EC%97%AD%EC%82%B0%ED%95%98%EB%8A%94_%EB%B0%A9%EB%B2%95\"><\/span>How to reverse calculate the amount including VAT in a transaction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When a customer asks, \u201cHow much is this item?\u201d and you receive a figure that already includes VAT, you face a situation where you must separate the supply price from the tax amount. The most common mistake here is <strong>Multiplying the included amount by 10%<\/strong>no see.<\/p>\n<p>Multiplying 55,000 won by 10% seems like 5,500 won, but the actual VAT is 5,000 won. Why is that? It is because the tax is already included in this amount. To calculate it backwards accurately... <strong>You need to calculate the tax amount by dividing the amount including VAT by 1.1 or 11.<\/strong>.<\/p>\n<p>There are many cases involving decimal points, but the Value Added Tax Act generally stipulates that amounts should be rounded up, down, or to the nearest 10 won. When filing, <strong>Check the rounding standards with the National Tax Service or a tax accountant.<\/strong>It is good to do it.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%EC%9D%BC%EB%B0%98%EA%B3%BC%EC%84%B8%EC%9E%90%EC%9D%98_%EC%8B%A4%EC%A0%9C_%EB%82%A9%EB%B6%80%EC%95%A1_%EA%B5%AC%ED%95%98%EA%B8%B0\"><\/span>Calculating the actual payment amount for general taxpayers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table>\n<thead>\n<tr>\n<th>Amount included<\/th>\n<th>Calculation formula (\u00f71.1)<\/th>\n<th>Supply price<\/th>\n<th>surtax<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>55,000 won<\/td>\n<td>55,000 \u00f7 1.1<\/td>\n<td>50,000 won<\/td>\n<td>5,000 won<\/td>\n<\/tr>\n<tr>\n<td>1,100,000 won<\/td>\n<td>1,100,000 \u00f7 1.1<\/td>\n<td>1,000,000 won<\/td>\n<td>100,000 won<\/td>\n<\/tr>\n<tr>\n<td>1,000,000 won<\/td>\n<td>1,000,000 \u00f7 1.1<\/td>\n<td>Approximately 909,091 won<\/td>\n<td>Approximately 90,909 won<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Let&#039;s take the first half of the year&#039;s tax return as an example.

Meanwhile, if the amount spent on purchases, such as coffee beans and store operating expenses, was 33,000,000 won, the input tax would be 3,000,000 won.<\/p>\n<p>If you subtract 3,000,000 won from 5,000,000 won, the basic tax payable is <strong>2,000,000 won<\/strong>That is it.

If you have a transaction for which a credit card or cash receipt was issued, you can receive an additional deduction of 1.31% of the issued amount.<\/p>\n<p>If this cafe issued card or cash receipts for 44,000,000 won worth of purchases, the deductible amount would be 572,000 won (44,000,000 \u00d7 1.3%). Then, the final tax payable would be 1,428,000 won (2,000,000 \u2013 572,000).

There is no concept of collecting purchase receipts to deduct tax; instead, the sales are multiplied by the industry-specific value-added tax rate, and then 10% is applied.<\/p>\n<p>For example, if the same cafe is a simplified taxpayer, the tax payable is calculated by multiplying the annual revenue by 151 TP3T (retail and restaurant VAT rate) \u00d7 101 TP3T. Since it varies within the range of 15 to 251 TP3T depending on the industry, it is important to check which industry you are registered under.<\/p>\n<p>Simplified taxpayers have simpler paperwork, but unlike general taxpayers, they cannot claim deductions for every single detailed transaction. Therefore, being a simplified taxpayer can be advantageous for small businesses with low purchase costs or high cash transactions, whereas conversely, being a general taxpayer may be better if material costs are high.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%EC%8B%A0%EC%9A%A9%EC%B9%B4%EB%93%9C%C2%B7%ED%98%84%EA%B8%88%EC%98%81%EC%88%98%EC%A6%9D_%EA%B3%B5%EC%A0%9C%EB%A5%BC_%EB%86%93%EC%B9%98%EB%8A%94_%EC%9D%B4%EC%9C%A0\"><\/span>Reasons why you miss out on credit card and cash receipt deductions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The point that many general taxpayers overlook is precisely this <strong>Card sales deduction<\/strong>You can receive an additional deduction of 1.31 for transactions where the customer pays with a credit or debit card, or even cash for which a cash receipt is issued.
