Financing
You can put a tax on a source, remove it again and see where KOSMA shows the tax.
Money from a source often carries VAT. A distributor advance is one example. When you put the tax on the source, the cash flow plan shows this VAT. To change a source, you need a licence that covers Financing, see [what your licence includes](/kb/article/what-your-licence-includes).
In the grid, click the source. **Source Details** shows its panels, **Taxes** among them.
In the **Taxes** panel, click  **Add tax**. KOSMA puts the first tax of the list on the source and opens the list. The list shows the taxes of the budget linked to the plan. Choose the tax that applies to this money.
In the **Amount** column, enter the amount of the source without the tax. KOSMA adds the tax in the cash flow plan. If you enter the amount including the tax, the cash flow plan counts the tax twice.
**A source has one tax.** If you choose a second tax, it replaces the first, the same as on a budget account. If two tax rates apply to the money of one source, split it into two sources, one for each rate.
The tax changes no figure in the financing plan: the **Amount**, the totals, the shares and **Received** stay the same. The **Refund** set for the tax makes no difference for a source. Without a tax on the source, the cash flow plan leaves out the VAT on this money.
In the cash flow plan, the row **Invoiced taxes** shows the amount of the source multiplied by the tax rate. For an **Amount** of 100,000 and a tax of 19 %, that is 19,000. KOSMA places it on the dates of the source's cash flow rule, or on the dates of each installment if the source has installments. Once per **Reporting Interval** of the tax, KOSMA offsets it against the refundable input VAT of the budget in one **Declared taxes** row. A source without installments and without a cash flow rule adds nothing to **Invoiced taxes**, and neither does an installment without a rule, see [set a cash flow rule on a source](/kb/article/set-a-cashflow-rule-on-a-source).
**Remove a tax.** In the **Taxes** panel, open the list and choose **--none--**. KOSMA removes the tax without asking you to confirm.
Hold Cmd (Mac) or Ctrl (Windows) and click each source. If the selected sources have different taxes, the **Taxes** panel shows:
Mixed contents · Click ↺ to reset
In that case, click  **Reset taxes**. KOSMA asks you to confirm, then removes the tax from every selected source. Then choose the tax as in step 2. KOSMA puts it on every selected source.
**If the tax you need is not in the list.** Choose **Edit** in the list. KOSMA opens the **Taxes** window, where you add the tax to the linked budget, see [define taxes](/kb/article/define-taxes). If the linked budget has no tax yet,  **Add tax** opens the **Taxes** window straight away. You can also click  in **Source Details** to open the **Settings** menu, and then choose **Taxes**.
