在购买首套房时，公积金可以用来支付首付。然而，并非所有情况都可以提取公积金来支付首付。那么，什么情况可以提取公积金首付呢？

首先，你需要购买首套房。如果你已经拥有一套房产，那么你可能无法再提取公积金来支付首付。此外，你需要支付一定的首付比例，通常是30%或以上。如果你的首付比例低于这个比例，你可能无法提取公积金。

其次，你需要有足够的公积金余额。如果你的公积金余额不足，那么你可能无法提取足够的资金来支付首付。此外，你还需要符合公积金提取的其他条件，例如缴纳时间、缴纳金额等。如果你不满足这些条件，你也无法提取公积金。

最后，你需要提交相关的申请材料。你需要提供购买房产的相关证明、公积金账户信息等材料。如果这些材料不齐全或不符合要求，你的申请可能会被拒绝。

总之，如果你想提取公积金来支付首付，你需要购买首套房、有足够的公积金余额、符合公积金提取的条件并提交相关的申请材料。
