Impact of Soc. Security Taxation on TIRA conversion to ROTH
I will be eligible to apply for Soc. Sec. in 2 years & want to convert some of my TIRA to a ROTH — was going to convert small amounts over next few (3-5) yrs (enough to keep myself in lower marginal tax bracket), but in reading — it looks like the amount converted would count toward AGI which would then trigger higher taxes on Social Security when I start collecting in 2 years. Am I right that the converted amount counts in AGI when figuring taxability of Social Security Income?
Thanks,

Yes you are correct, the amount converted to a Roth does increase your AGI to see how much of your social security is taxable.
You still may be better off doing a gradual conversion though. Most people pay tax on 85% of their social security any way; the Roth conversion won’t increase that. If you do a conversion all at once, it could affect your Medicare premiums 2 years later. Medicare has a base monthly premium but high income taxpayers must pay more. The AGI limits for that are available from Social Security.
When you call to start Medicare or Social Security the personnel there can be very helpful in explaining how Social Security is taxed and how Medicare premiums may be increased. It’s best not to call on a Monday, they’re very busy that day.
