领主税

一笔巨大的收入来自你的封臣.

一个公式，每个封臣分别如下:

领主税 = 封臣收入 x 税收比率 x 惩罚修正

其中:

• 封臣收入 是封臣的全部稳定收入.它包括了封臣的直辖收入, 领主税来自他们的自己的封臣和贸易收入.
• 税收比率 领主法律设置之一. 分别应用于的封臣所拥有的不同 政府 类型。
• 惩罚修正 可能会被应用于:
  • 负面观点:-20好感-20%税收, 诸如此类
  • 超过封臣限制: 取决于超过封臣上限的数量比例.
  • 贵人（共和国）: -50% for vassal patricians (including vassal doges)
  • 超过直辖领限制:超过 -20% 每县/地产 , 最多超过5个 -100% .

封臣支付收入在领主的封臣页面中展示, 以及所有的每个封臣的政府类型也同样被展示在领主的 demesne screen.

税收法律

税收法律是领地中 地产法律 (未启用御前会议) or 领土法律 (启用御前会议).

未启用御前会议

Without Conclave, there is a tradeoff between taxes and vassal opinion.

Beware of the side effects of increasing taxes: while maximizing income is pretty simple, it can have a drastic effect on other areas of your realm. Increasing taxes on nobles (without Conclave DLC) make them like you less, and thus make them more likely to rebel and give you less levies. Too high taxes can thus make your realm considerably weaker, and massively increase internal turmoil. You can thus easily end up spending more time and money on placating your vassals and putting down rebellions than you earn in increased income. This is especially important to consider when it comes to the Catholic clergy. So while you might end up earning more money, if you're not careful you'll never actually get to use that extra money for anything useful, instead using it up in unit upkeep and bribes.

It is relatively safe to raise taxes on mayors, as they can't rebel and barely provide troops anyway.

If your realm is stable, you may consider taxing nobles as well. Your successor will not need to be popular in order to eliminate these taxes after you die.

最大化

Now that we know how tax works and what affects it, we can now work out how to maximize it. First we've got simple construction, which will directly increase the income of a holding, which will trickle down as tax. Constructing buildings in your vassals' holdings gives less of a return on your investment than building in your own demesne. As such, when seeking to maximize income, you should build as many income buildings in your demesne as possible. However, funding construction for your vassals will increase their opinion of you for some time; weigh your options and plan accordingly.

Next, you can increase the tax law to make your vassals pay more. However, if their opinion is already low enough, this will not pay off, with a full list here:

• 10% -> 20% gives more as long as opinion is originally above -80 (0.1 * 0.2 = 0.2 * 0.1)
• 15% -> 25% gives more as long as opinion is originally above -75 (0.15 * 0.25 = 0.25 * 0.15)
• 20% -> 30% gives more as long as opinion is originally above -70 (0.2 * 0.3 = 0.3 * 0.2)
• 25% -> 35% gives more as long as opinion is originally above -65 (0.25 * 0.35 = 0.35 * 0.25)
• 30% -> 40% gives more as long as opinion is originally above -60 (0.3 * 0.4 = 0.4 * 0.3)
• 35% -> 45% gives more as long as opinion is originally above -55 (0.35 * 0.45 = 0.45 * 0.35)
• 45% -> 55% gives more as long as opinion is originally above -45 (0.45 * 0.55 = 0.55 * 0.45)

As such, higher tax will almost always equal more income, but this does not take into account the hit to levies, nor the chance of rebellion. For Catholic clergy, it's best to leave clergy tax rates at 35%; any increase might anger them to the point whereby they pay taxes to the Pope and withhold levies from you.

启用 御前会议

御前会议DLC处于激活状态, 税收法律取代了义务法律, 允许统治者去 移动 强制提供的领地内的封臣义务, 更多的税收或者更多的征召兵. 这也意味着法律修改税收将不会增长或者减少附庸的好感。

大多数的统治者会市民义务移动向更多的税收而贵族义务会移动向更多的人力. 然而, 内阁中的附庸更喜欢相对平衡的观点他们会花费 人情 去强制法律投票.

拥有更多的附庸商业共和国

如果你有大量的军队, 考虑 转化 一些封臣城市变成巨大城市:

• 领地的市长会支付基于城市法律税收的赋税。
• 授予一个公爵头衔给一个沿海的市长，他会让他变成一个新的 共和国总督。在几年后,会建设贸易站，共和国关联所有城市会开始产生财富
• 市长和共和国总督可以持有额外的城市. 在他们赢了圣战以后, consider vassals rather than giving them away along with the county title. 他们会抱怨新任命的市长而不是你,因为缺乏对当地城市的控制。

任命对立教宗

主条目：对立教宗

天主教牧师如果比起教宗他们更喜欢你，他们会支付税收给你。 由于他们通常对教宗的好感通常在+40到+60，使得他们喜欢你比喜欢教宗变得非常困难。一个特别有效的方法是设立对立教宗，你会得到所有的他们支付给对立教宗的教堂税收，然后每个主教他们会从喜欢你和喜欢对立教宗之间选一个，但都会超过喜欢真实教宗，他们最终会支付给你教堂税。 除此之外, 每个主教都会支付税收给你，如果他们喜欢对立教宗超过他们喜欢真实教宗或者他们的领主。如果你统治了大量的领土.教堂税会因此最终成为你领土里的巨大收入资源。

一个好的对立教宗可以征收大量的教堂税从你的王国中，这很容易让你从你的直辖和直接附庸那里收税变得相形见拙。 一个 好的对立教宗 甚至可以征收教堂税来自其他人手中的天主教教堂，（其很难征收宗教税从其他领土上的一个原因是，官方的宗教教宗有一个+30好感增长修正）
