If you exceed the contribution limits for a deduction from an IRA, and also the Roth contribution limits, you have the opportunity to do what is known as a "back door Roth". It is legal and tested in the courts, but is certainly doing a bit of a work around the existing regulations.
It involves making a non-deductible contribution to your IRA, then in the same year roll that contribution into a Roth contribution. You pay the taxes as you would any other Roth. It allows high earners to still get that Roth contribution. One hurdle however is if you have any pre-tax money in other IRAs (traditional, simple, or SEP), then you have to pay pro-rata taxes on the rollover. It can be complicated to try to extract that IRA money. In may case I had to roll it into a 401k that had questionable investment options.
